Clean, safe water is crucial for maintaining good health and well-being in your family. Although this may be taken for granted in many parts of the world, tap water is usually treated. However, it may still contain chlorine, lead, or even bacteria depending on your region. A great solution that improves water quality right at the source is installing an under-sink water filter. Choosing the best undersink water filter for your house is discussed step by step in this article, along with the different types of filters and considerations one must look into, along with top recommendations.
Types of Under-Sink Water Filters
Choosing any under-sink water filter requires one to understand the various types of filters available. Each system operates differently in its unique filtration method and may target specific contaminants.
1. Activated Carbon Filters
The most prevalent variety of undersink water filtration systems is the activated carbon filter. These filters purify by passing the water via a bed of activated carbon, to which contaminants become absorbed. Activated carbon filters are very effective at removing chlorine, sediment, and VOCs, which improve taste and odor. They have generally low effectiveness against dissolved minerals and other heavy metals, such as lead.
Best for: The removal of common pollutants and the improvement of taste.
2. Reverse Osmosis Systems
Reverse osmosis systems are more sophisticated and provide complete filtration. Water is forced through a semipermeable membrane, which can remove virtually everything from heavy metals such as lead and arsenic to fluoride, nitrates, and bacteria. High-purity water is produced in this technique; however, it can be slower and may waste some water in the process.
Best for: High level of contaminant removal, including heavy metals and bacteria.
3. Ceramic Filters
These filters work in such a way that they can stop bacteria, sediment, and some parasites by using a porous ceramic material. Commonly, most of these filters work by mechanical filtration. Moreover, they work well with the elimination of microorganisms from the water. However, they are not effective in removing the chemical contaminants in water.
Best for: Eliminating bacteria and parasites.
4. UV Filters
UV filters purify water with the help of ultraviolet light by killing bacteria, viruses, and other pathogens. While they are extremely effective in the disinfection of water, they neither remove any kind of chemical contamination nor sediments. UV filters can also be installed as part of another filtration system for broader coverage.
Best for: Killing bacteria and viruses.
Key Factors to Consider
Here are some key things to consider before buying an under-sink water filter to make sure you select the appropriate system for your home's needs.
1. Contaminants in Your Water
Understanding what impurities are in your water is the first step in choosing a suitable filter. You can test your water using home testing kits or check in with your local water supplier for a water quality report. Once you know what the contaminants are, you'll be able to match those contaminants with the right kind of filter.
- Chlorine, VOCs: Activated Carbon
- Heavy Metals, Bacteria: Reverse Osmosis
- Bacteria, Parasites: Ceramic
- Microorganisms: UV Filters
2. Flow Rate
The flow rate denotes the quantity of water it can filter within a minute. Some filters, like reverse osmosis systems, even have lower flow rates, which may affect everyday usage of water. Pick out a filter whose flow rate corresponds to the demand for water by your household.
3. Filter Life and Replacement Cost
Different filters boast different lifespans, anywhere from a few months up to several years. Consider how often the filters will have to be replaced and how much this will cost over time to ensure you are not over-investing in upkeep.
4. Installation Requirements
Some under-sink filters require professional installation, while others are designed to be easily set up at home. You may wish to find a system you can set up yourself if you know your way around basic plumbing to save on costs.
5. Size and Space
Ensure that the filter system will fit comfortably under your sink. In cases where the space is small, seek out compact models that can deliver appropriate filtration.
6. Certifications and Standards
Seek filters certified by organizations such as NSF/ANSI. A certification by such organizations means that the filter has been tested for its quality and effectiveness in removing specific contaminants.
