Product's Review

      I ordered this system for a family house and it's what I expect. Water purified down to a TDS reading of 2ppm from about 80ppm untreated. (Posted on 1/5/2019)

    2. Great Product Review by Jeremy

      Purchased RO System about 1 year ago. The tap water tested 75 ppm. After installing RO system water tested 2 ppm. Very pleased with this product! Highly recommend! (Posted on 12/22/2018)

    3. Healthy Life Review by EllenM

      Water tastes fresh straight from the faucet now. It is easy for me to install and now my coffee taste so much better and I feel like I’m drinking something healthy. (Posted on 11/19/2018)

    4. Good Customer Service! Review by Steven C

      This system is very good and as long as you follow the steps mentioned in the manual you have nothing to worry about. The installation was pretty easy, so read the instruction manual first before you install it. Overall the installation took me about 1 and half hours.

      We had installed the RO Water system about 5 month ago actually and my wife and I have been very happy with it. The water from this unit is so clean and the ice maker ice is almost clear. Measuring with a TDS meter, water straight from the tap measured 147 ppm down to 5 ppm. This system changed my water quality in a significant way. We do not have to buy any bottled water anymore. This system exceeds my expectation as it’s absolutely tastes same as the bottle water that get from the store. I am so happy we bought this filtering system. I highly recommend it.

    5. Amazed!! Review by Ed Braun

      I just bought and installed the RO-90 system 2 days ago. Our city water is HORRIBLE!!!!! and very hard. The system was very easy to install and I didn't have to buy any additional parts not even to hook up my ice maker. COOL... I tested my tap water with the TDS meter and it was almost 1,200. I tested the RO water 88.. WOW!!! I had my first glass of water yesterday and was very happy with the outcome. Even my ice looks clear like it should be. I am so glad I decided to buy this system and hopefully will get alot of good years out of it. I just recommended it to my father-in-law for his new house. Thanks for a good product at a fair price!!

      The quality of the water coming out of this unit is unbelievable! I love it and the installation was easy. I like that you don't have to mount the system since it easily sits on its base under the sink. (Posted on 3/29/2018)

    13. Five Stars Review by Ashley Rivera

      We love it. The water has the best taste and easy to install as well. (Posted on 3/8/2018)

    14. Clean and clear ice cubes! Review by Kent

      Two years ago we moved into the country and found out that our well water was high in nitrates. After much research and looking through a lot of comments, we decided to purchase an APEC RO-90. It has been one of the best decisions we have made. We noticed a difference almost immediately in our ice maker, clear ice cubes! Our coffee, juices and lemonades all taste better. Our coffee maker never needs to be cleaned and lasts longer. Thanks to APEC for making a great product. (Posted on 2/4/2018)

    15. Love my water now Review by Benny Tran

      No issues. I did a lot of research before buying this. It has enough capacity for our family and the water tastes way better. Customer service was able to answer all the questions for me. (Posted on 1/19/2018)

    16. Totally worth it Review by John

      Well I'm back to order new filters. I've been using the RO-90 now for four-years without any problems. Filter changes are very easy. The water hardness here in Clovis NM runs between 375 and as high as 425 at times. With new filters installed the RO-90 system test below 25 and after a year's use test below 40. With a family of five, I can't tell you how much money that I've saved not having to buy bottled water, but I'm sure this unit has paid for itself many times over. Everyone who has been to my house and has drank my water was amazed with the quality and taste of the water and normally had seconds and thirds, they/we love the water. We boil lots of water for coffee and tea, before this RO unit was installed we would have to clean our equipment on a monthly basis because of the hard water; not anymore. I have not cleaned any equipment in over four-years now. The tea kettle is just as shiny and new as the day we bought it. The price for this RO-90 System is very in-expensive, high quality, and a must own no matter where you live if you want clean water. (Posted on 12/30/2017)

    23. water tastes great Review by A A

      This was much easier to install then I imagined. Hardest part was installing the faucet since we need to drill a hole. According to the instructions you do not need to hang up the filters which worked really well for us. Makes it easier to change in the future as well. The water tastes great from the system, you don't realize the water is so great UNTIL you drink bottled water and tastes the difference. (Posted on 9/2/2017)

    24. Easy installation, Review by Dina Flores

      Easy installation. The product showed some impressive filtration results, the water hardness in my home area is around 250; after using the APEC RO-90, it went straight to 5, and it had been staying below 10. (Posted on 8/30/2017)

    48. RO-90 Review by Wes Titan

      I purchased this unit and received it fairly shortly. I was glad that it came with a water tester as well. installation as simple enough, there were a few steps missing detail like the fact that you need to put plumbers tape on the fitting on the top of cap. But overall it was great, the water was coming through at 440-460 ppm, after installation of APEC RO-90, I got a reading of 6 ppm at the lowest once. (Posted on 4/21/2016)

      The system arrived very well-packed and in new condition. The unit was relatively easy to install. No noise and no leaks. There were tiny bubbles in the water initially but they cleared out within the first day of using the system. (Posted on 1/22/2015)

    76. Five Stars Review by Jose Sanchez

      This system is very quiet. The water quality is great. I set up this system in less than 2 hour. I read the manual and it helped a lot. I also called the customer services and they seem always there to help me. I love this product. (Posted on 1/9/2015)

    77. Good Review by Wdm3d1

    81. One year user Review by One year user

      We purchased this RO system one year ago. The quality of our drinking water is just great. Almost all of my friends and relatives who come visit me comment on how pure and clear the water tastes. I would highly recommend this product to anyone. (Posted on 9/22/2014)

    83. Absolutely Excellent! Review by John Roberts

      Absolutely Excellent! Couldn't be better. Changes nasty Phoenix water from 510 TDS smelly highly chlorinated to clean 24 TDS bottled water quality. PH before & after is the same at 7.6. Made in USA components, all heavy duty. Everything fit - everything worked the 1st time. AND ... no noise or gurgle with the their non air-gap faucet. Installed drain saddle on top of the horizontal run between garbage disposal & drain sink. Also installed their 3/8" high volume dispenser kit and have plenty of flow to quickly fill coffee pot. Purchased extra filters for YEARLY change out.
      (Other brands required every 6 months) I called Customer Service twice. Both times answered quickly and professionally with good advise. Good instructions and color illustrations. Five Stars for the product, the results, and Customer Service. Highly recommended! (Posted on 8/31/2014)

    85. This water system tastes so good. Its like buying top quality water Review by York

      The water tastes so much better and smooth. Love it. It is simple to install and worth the price. (Posted on 7/11/2014)

    86. GREAT BUY! Review by DLaw

      In the middle of a home remodel and this has to be the best $300 purchase in years. I live in Duncan, OK and the water here is foul tasting. The installation was easy, and the quality is top notch. The water went from 450 ppm to under 30 ppm. I have six kids and they all love the taste of the water. So far this RO-90 provides plenty of water for all of us and we drink a lot. I estimate that based on my water pressure my system makes between 30-36 gallons a day which is more than enough for us. (Posted on 6/19/2014)

    87. Very Nice System Review by Josh B

      I purchased RO-45 two weeks ago, and so far I am very pleased with the results. The water quality is excellent, and the system was a little tricky to install, but not to difficult. I definitely recommend this product. (Posted on 6/5/2014)

    88. GREAT PRODUCT! Review by DLaw

      I forgot to mention that the customer service I received when I had a question, during ordering and delivery was some of the best. I will be ordering another for my in-laws in the near future. (Posted on 5/22/2014)

    89. No more bottled water! Review by Mary West

      We were thrilled to receive the red, white, and blue box containing your RO-90 water filtering system with "made in USA" printed in large letters on the outside. What a great quality product, very simple and quick to install. Our water taste fresh and pure now and after conducting a couple of test on the quality of the water; tap versus filtered with the RO-90. I shudder to imagine all we have ingested all these years. Now no longer hauling all those water bottles from the longer feeling guilty about filling our longer worrying about drinking from the plastic bottles. Thank you!!! (Posted on 5/10/2014)

    90. Highly recommend the APEC sytems! Review by Eric Landon

      I purchased the RO-90. I used the free TDS meter to test my water prior to installation. Out of the tap it was 440 TDS, with the old RO it was 79 TDS. With this new system it's 19 TDS! That's huge! I am so happy with the RO-90. The water tastes so good and our ice is now crystal clear. I bought the kit to increase the flow and it fills my huge water jugs in no time. I highly recommend the APEC sytems! (Posted on 4/18/2014)

    93. Excellent! Review by Robert White

      Hubby installed the system. Instructions were clear and he had no problems with installation although, admittedly, he is very much a handyman and do-it-yourself guy. We decided today to order the Ultra-Violet light to add to the disinfecting properties since we have a private well. Our RO-90 water tastes wonderful - so clean and crisp! The water pressure is good too. We could not be more pleased! (Posted on 11/1/2013)

    94. Simple install Review by James

      I was impressed right from the start. Upon opening the box I saw the best, neatest, orderly packing job that I have ever seen on anything that I have ordered by mail. Every thing was well placed and packed tightly. Excess space (which was very little) was filled in with air filled plastic packing, not Styrofoam peanuts (I hate those things). Everything was completely in tact and ready to install. The installation was very simple, mostly because I already had an existing filtration system.
      Before I removed the old system I used the TDS water tester that came with the unit to test the water from the faucet and the water from the old system. To my surprise they both read 148 on the TDS! No difference between the filtered and unfiltered water. I followed the instructions for installing the new unit (very plain and straight forward) after removing the under-the-counter filters from the old system. I used the existing fill tube, inlet water valve, outlet tube, and dispenser assembly, making the installation much quicker. After finishing and checking for leaks (there were none) I tested the the the RO-90 with for TDS again. It read a TDS of 4, a very big difference. I also found that the water tastes enormously better. The improvement is quite noticeable to the taste. Needless to say: I am very, very satisfied. Everything concerning this reverse osmosis system shows of a company that takes pride in their product, pride in their packing facility, and truly cares for their customers well being.

    95. Made in USA! Review by Allen Downs

      As part of my 2010 new years resolutions I made a promise to myself to be more healthy in life. One of my steps in this promise is to drink more water. I had a major well known water company come in and test my water. After they really showed me how much sediment/junk is in our water, I was almost disgusted. They offered their solutions to fix my water problems and honestly I was shocked. They wanted to charge me $899 for a reverse osmosis system. I have basic city water nothing special about it. I was determined there has to be a better solution out there. I ended up doing research and for some strange reason out of all the solutions out there seemed like the most bang for my buck and the most quality system. I've talked to Henry via chat several times and he was very polite and answered every question I had. I ended up ordering the RO-90 and upgrading the system to the 3/8 inch tubing to fill my containers quicker than the 1/4 line. I also wanted to increase my pressure to my ice-maker/refrigerator. I saw a few other setups and liked the idea of the pull out filter assembly.

      When I received the RO I was very impressed with how green they were with their packaging. It was very well designed and utilized packing very well. I thought the quality of their filtration system was absolutely the best. I ended up starting out with water that is 360ppm and after running the filtration unit, I now get water that is 18-20ppm. I was absolutely shocked. I decided to test a name brand bottled water that I drank all the time. It tested 30ppm. I now have even better water than what the major soda manufactures are putting out. Plus I also got some great bpa free bottles and I am set for life! My next goal is to share with my entire family and get me as many referrals as I can!

      Pros: Excellent directions, top notch quality design (and made in USA), customer support was better than any other company I've seen, I feel their website really "educates" you about the options of water health, now it makes me want a whole house water filter and softener.

      Cons: Since I upgraded the system to 3/8 they left a few items out in the directions stating I would not have a yellow 3/8 line or I wouldn't need some of the fitting they included. I wish the coke chrome faucet was also made in the USA, but it is still top quality. (Posted on 7/20/2013)

    96. Great value Review by Julian V

      I am very very pleased with my RO-90 system. Bought it and had a professional install it since I am not good with pipes and hoses. The system arrived quick and very well packed, all information and hardware needed for installation was delivered, (the plumber was impressed too). I called the support line with questions and all of them were answered clearly and very cordially. I highly recommend this water filter and the company because I believe they are simply very professional at what they do. (Posted on 6/30/2013)

    97. Fully satisfied Review by Dave B

      I chose to install the unit in the basement as I did not want to lose the space under my sink upstairs. Also, I felt that having the unit mounted to the wall would make future filter changes easier. Ken in customer service is excellent! He answered all the questions I had regarding the RO-90 and other whole house filtration products I am considering. I purchased your product largely because of Ken as he is very confident and knowledgeable about your product. When I received the RO unit I was immediately impressed by how well it is packaged and how solid it looks/feels upon unboxing. The instructions are very straight forward and easy to understand. The install was a snap. I also purchased the ice maker kit so I could hook the RO water up to my refrigerator.

      I will definitely recommend your company and product to my friends and relatives. It is definitely a great value for the quality you receive. Thanks APEC! (Posted on 2/28/2013)

    98. This is already the 4th APEC RO system I purchased Review by Alan Namazbayev

      I just wanted to express my deep appreciation of business I had and still luckily have with APEC! This is already the 4th RO system I purchased from APEC and I'm 150% satisfied by the quality of the water it produces as well as parts and assembly quality of the RO system itself. I've installed 3 RO systems for my closest relatives and one for my newly purchased home in Austin and now we all drink crystal clear and safe water!

    99. Great customer support Review by Russell Dunham Jr.

      Our experience with your under sink filtration system has been great! We have your RO-90 System.We had to purchase some parts to make a repair today. Your website is very user friendly and a delight to use.
      Later we called and spoke to one of your most helpful, knowledgeable Staff members on the phone who knew exactly what I needed and arranged for my parts to be paid for and ready at the door when we arrived to pick them up. When picking up, the Staff members we dealt with at this stage were more than helpful.

      Prior to leaving your facility, we decided to stop up front and spoke to a VERY knowledgeable, and VERY helpful man who gave us more information we needed and made us feel confident that we WILL continue as a satisfied customer of APEC Water Systems. (Posted on 10/23/2012)

    100. Easy filter change Review by John

      I just wanted to drop a line and say your system is great. I never comment on websites or products, but felt it was good to let you know how well things have worked out. I have an RO-90 and installed it myself about 3 years ago. Before we got the RO, our well water always had a taste to it. We have a whole house water softener (our water is about 25 grains of hardness), as well as a whole house sedimentation filter. The water still tasted off and still had a slight brown staining. Our TDS was almost 1000. We installed the RO and the water tasted great, the staining went away, and our TDS dropped to about 175 to 200.
      In addition to saving on buying gallon jugs of water from the store, we no longer deal with bottles of water sitting on the kitchen floor and our overloaded recycling bucket every week. We are a family of 5 and never run the unit out of water. The system is great, durable, and switching filters is super easy. Nice product! (Posted on 10/10/2012)

    101. Awesome, Awesome, Awesome Review by Evan Gary - California

      I bought the Apec system after using Arrowhead, Sparklets..... I can't believe I waited so long to buy a system like this. I will describe it in 3 words.... Awesome, Awesome, Awesome. The water tastes so much better than the water from Arrowhead or Sparklets and you will save a Ton of Money..... You will be totally amazed once you start testing the water that comes out of the tap and then testing the water that comes out of your new
      system. You kinda will feel like a mad scientist :) Anytime someone comes over I am proud to ask "You want some water" and they always say that is good tasting water.... The End (Posted on 8/3/2012)

    102. Great product, good customer service Review by Yang Wu - Flushing, New York

      Great product. Good customer service upon contacted. The system is easy to install w/ the help of the clear instructions, and pretty solid after constructed. The system works automatically and quietly. Feeding /raw water of 39 ppm produces water under TDS meter detectable range, ie. 0 ppm.) (Posted on 7/18/2012)

    103. System removes FLUORIDE! Review by Neil - Houston, Texas

      The RO system works well. I have tested lab distilled water for fluoride levels as well as popular water bottles. The APEC RO system has the LOWEST FLUORIDE levels of any of the waters I have tested! The level is slightly lower than Nestle bottled water. My APEC water tested at 18-19 us conductivity! Thank you!

    104. Never go back to drinking tap water! Review by Brian W - Iowa

      When I got my filtration system I couldn't wait to hook it up. When I finally did the whole procedure it only took an hour or two. Instructions were easy to follow. I did have one small leak but only because I didn't tighten a nut as tight as I should have. Once I tasted the water, I never want to go back to drinking tap water again! My numbers before were 400-500ppm and now are at 25ppm. I use the water for everything, even rinsing vegetables! I would recommend this system to friends and family. Whenever I move I will be sure to take this system with me. (Posted on 6/16/2012)

    105. 10 stars Review by Hassan

      I bought the RO-90 system couple years ago. This is one of the best decisions I have ever made. The water tastes great. The system is low maintenance. I am very happy with this product. On a scale of 10, I give it a 10. (Posted on 3/12/2012)

    106. Durable system Review by Vince George

      I've had my RO-90 system for 4 years now and all I can say is that it was the best $300 I've ever spent. I am still amazed at how this system can take terrible tasting municipal water and turn it into such great tasting water. In fact the water tastes better to me than any bottled water I've had. The RO-90 has worked flawlessly ever since I've had it. I even recommended this system to a friend and they are as happy with theirs as I am with mine. If your looking for a great RO filtration system look no more, this is it. Thanks APEC for a great product! (Posted on 2/16/2012)

    107. Could not be happier Review by Michael Mona

      Hey APEC! I am coming up on my 2nd year on this new RO-90 system... How's it doing? Well I just tested the water from the tap... 900 ppm of stuff in the water. YUKK! After going thru the RO-90 it is now 31 ppm. 96.55% Pure. Pretty darn good! I've changed the pre & carbon filters recommended on the yearly schedule. Thanks again for the well made product.

    108. Easy to install, great tasting water, and made in the USA! Review by Roger Whittaker - Lake City, Georgia

      This is a great system. Easy to install, great tasting water, and made in the USA! I believe this is a great value. My refrigerator has a filter that costs $60 every six months, this system's filters cost $39 a year. That is a big difference in cost, and this system is much better than the one in the refrigerator. Now, I have clean water to cook with and drink. I also ran a line to my refrigerator so I don't need the filter on it and can have nice clean ice and still use the water in the door. I would say this is a great deal. (Posted on 10/4/2011)

    110. No more chlorine smell Review by James Barton

      I do sincerely love this RO90 water filtration system. My tap water went from 190pm, to 3ppm, thats a tremendous difference. There is no chlorine taste or smell, no nothing, just pure clear clean water.... Installing it was easy with this wonderful product. I cannot see how I could go without one now...Ever! Thank you so very much. The quietness of my coffee maker was well worth the filter price alone by the way. The Tds meter was a plus and yes I tested my coffee as well, just so you know 464 ppm coffee. Knowledge is a wondrous thing indeed. Thanks again from a very happy customer here!!!!!

    111. Feel healthier Review by Elizabeth Vesely

      I am very happy with my RO-90. I have been struggling with migraines, acid reflux for a while and I also had some odd abdominal pains. Since I started drinking the RO water, the frequency of my migraines has decreased, the odd abdominal problems stopped. I'm also not generally as sick as I used to be. I'm feeling better and no more lugging bottled water from the store. I also got the twist on shower filter and I could breathe after getting out of the shower. My hair and skin are in better condition. My daughter and I have thin hair and the filtered water makes it so soft and manageable. It's worth more than I paid that's for sure. I'm so glad they made this product affordable to the average person. I couldn't be happier. (Posted on 7/15/2011)

    112. Great price Review by Richard Wise

      Thanks APEC Water Systems (& Ken) for helping me locate the hard to find RO membrane for my mom's older RO system and selling it to me. I installed the membrane this weekend and it's working like a champ. She's also got a APEC 45gpd RO system that I bought from you a couple of months ago and installed in a new addition she had added to her house. The APEC system really does a much better job (more throughput and better filtering) than her older 15gpd system from another manufacturer. I'll keep recommending your APEC RO systems to anyone that I find is looking for an excellent RO system at a great price. (Posted on 6/27/2011)

    113. Water tastes great and quality is excellent. Review by Chung Chang - Texas

      Used for about a month now. Replaced a leaky Whirlpool 3-stage RO filter purchased from Lowes a year ago. Whirlpool might have been cheaper up front, but the flimsy build quality and more expensive replacement filters make the APEC much more economical in the long run. I would break even in about 3 years and after that, save twice as much on filter replacements. Water tastes great and quality is excellent (TDS = 220ppm@faucet vs 22ppm@APEC spigot). Also plumbed to fridge icemaker and no longer need to clean hard mineral deposits on the ice/water dispenser catch pan. Highly recommended! (Posted on 6/12/2011)

    114. Clean water for my kids Review by Jarrod Pearson

      I purchased the RO-90 a little over a year ago and have had no problems with the unit at all. No leaks and all the clean water our kids could drink. I just replaced the first three stage filters and I was shocked to see what just the 1st stage pre-filter caught from our "Superior" municipal water district! YUK! I am loving this system!

    115. Smooth installation Review by Jeff Greer

      Installed the RO-90 two years ago. Good instructions and easy installation. As others have stated, we had enough of lugging 5 gallon bottles onto a cooler as well as the increasing cost of delivered water. This system produces excellent tasting water, so everything made with it tastes better. My wife loves her tea more than ever. Easy to maintain at relatively low cost. Thanks for a great product and service. (Posted on 4/4/2011)

    117. Tastes as good as bottled water Review by Charles Merkel

      I received my RO90 system last Monday and installed it on Tuesday. My primary purpose for installing this unit was to eliminate the need for hauling 5 gal bottles into the cooler several times a week. We live in a city with a highly rated water system but we just did not like the chlorine taste of the tap water nor the taste that it imparted into the coffee and tea. So for years we have tolerated the bottled water. However, as age catches up with you, it became more and more of a challenge to handle the bottles. So the RO90 and a new refrigerator with a water/ice dispenser system was in order.

      After following the instructions regarding flushing and clearing the tank and lines, I ran some tests using the meter device provided. I used three samples of water after the unit had run for two days and had sufficient time to clear all the tubing. The tap water read "191" and the water from the filter system faucet read "007". The water from the refrig faucet read about "024" but I subsequently removed the filter provided with the refrig and brought that number to be the same as the faucet at the sink. The main test however, is that the chlorine taste is gone and the coffee tastes as good as using the bottled water. The bottles and the cooler are a thing of the past. So far the unit is performing as I expected. A satisfied customer. (Posted on 2/4/2011)

    118. Amazing test results from the TDS Review by Vaughn T Hazell - Anguilla

      I am from a tiny island in the Caribbean called Anguilla, where I am currently building my house, with anywhere between 5 and 10 guys carrying out the construction of the house on a given day. Before purchasing this system I would normally spend about $20 USD a day on water and ice for the construction workers alone, and following the recommendation of a friend I decided to purchase the RO-90 system as a means of cutting costs. I must say that since installing the system, I am convinced that this has been the best investment I have ever made in my life so far. I have gone from spending over $100 a week on water for my workers and our home to $0.00 dollars. I was simply amazed by the test results from the TDS system, where the results showed that the filtered water from the RO-90 system was even better than the bottled water.

      I work for the Government of Anguilla and I have already submitted a request to my PS about purchasing a few of these devices for a number of departments, as a means of saving money. My brother who works for the only secondary school on the island has also convinced the Principal to purchase a RO system for the teachers in that school. I absolutely love this system and would recommend it to anyone who is looking for an excellent system for producing clean drinking water. (Posted on 1/2/2011)

    121. Water tastes sweet Review by C Bailey

      After much contemplation about spending the bucks to purchase a RO unit, I took the plunge. This is very definitely a quality product and it works like a charm. And it was easy to install, no plumber needed. I live in the country so the water comes from a well. My water pressure is very good so I went with the RO-90 and it is perfect. My house water is softened and I didn't want to drink softened water, plus it tasted terrible. No more buying bottled water for this gal. My pets love the water too. My coffee tastes even better and that's great news! Don't wait... get this product and you'll be as happy as I am. :))) (Posted on 8/27/2010)

    122. Water tastes great Review by Rich

      Bought the RO-90 with the SS Faucet. All came nicely packaged with very good, and easy to follow instructions. I installed it myself and it only took a few hours.

    123. Loving my RO system from APEC Review by Michele Monk - Mississippi

      Loving my reverse osmosis system from Free Drinking Water. I have breast cancer, and am treating it with Gerson Therapy. With this therapy I am not allowed to come into contact with chlorine or fluoride. The water is also used for coffee enemas. I asked my local water company to test for both of these after running the water through your filter, and the fluoride which I was very concerned about had gone completely. I am saving up for a whole house system so I can have a shower, been doing sponge baths with heated filtered water for the last 2 months. A friend of mine fitted the system for me and said it was easy to do. When the automatic shut off valve quit working, your technician explained what I had to do with the system to diagnose the problem with lots of patience, the replacement part was very easy to install. I own a natural healing center, and am going to recommend the system to over 700 of my clients. I am sending pictures of how much water I had to buy for the 5 days that your system was not functioning, made more more grateful for your system. Blessings for a healthy day. Michele Monk.

    124. Good customer service Review by James Bullock

      I am very pleased with your company sales and service personnel. Also I am pleased with the quality and price of your RO90 product. The instructions were good and I have successfully installed the RO90 unit. I have a suggestion for your instruction manual. My suggestion is to include the need of the insert on page 14 and 15 in the items 4, 5 and 6. I had to go back to page 11 & 12 in #2 to be sure that I was to use the inserts because it was not mentioned on page 14 and 15. I only mention this to be constructive and helpful.

    125. Great tasting water Review by Dave C

      We installed our RO-90 about 3 weeks ago when we had a new water softener installed. We installed the RO-90 unit in the basement next to the water softener and have the tank there too. We ran the fresh water line up to a T and have the great tasting water going upstairs to our new faucet and fresh water in the refrigerator and for making ice. One thing I noticed is that the ice cubes are clear now. I love the idea of filtering the crud from our drinking water. Thanks! (Posted on 1/7/2010)
