The 4 Best Under-Sink Water Filters of 2022 for Safe, Clean Tap Water
Amazon Installing an under-sink water filter is a quick, practical, and cost-effective solution to ensure that the water coming out of your faucet is safe and delicious. And it’s possible that the upgrade is even more crucial than you realize: However, while the United States has some of the cleanest drinking water in the world, the situation is far from ideal. Tap water contaminated with lead is a persistent problem, and it is not limited to communities such as Flint, Michigan. In the United States, as many as 10 million houses are connected to water through lead pipes and service lines, which is why the Environmental Protection Agency (EPA) is working to improve its lead and copper restrictions.
These so-called forever chemicals — which are used in the manufacturing of some consumer products as well as firefighting foam — are contaminating ground water supplies at an alarming rate, to the point that the Environmental Protection Agency issued a health advisory as a result of the contamination.
What are the benefits of an under-sink water filter?
In spite of this, even if your home’s tap water is free of contaminants, it may still have an off-putting taste due to the chlorine used by public water systems to destroy disease-causing organisms such as Salmonella and Campylobacter. In order to ensure that all forms of water filtration equipment, from simplewater filter pitchers to complicated whole-house systems, are thoroughly tested by the Good Housekeeping Institute. While those alternatives have a place in the market, our experts believe that under-sink water filters are the best solution for the majority of families.
Our engineers have discovered that the top under-sink water filters perform well in terms of eliminating impurities while remaining unclogged.
According to Rachel Rothman, chief engineer at the Good Housekeeping Institute, where she oversees our water filter reviews, “Under-sink water filters take up a little cabinet space, but they don’t clutter the sink deck the way countertop water filters do, and they’re not clunky like faucet-mounted filters.”
How we test under-sink water filters
In order to reduce the field of candidates, our specialists analyzed only water filters that were certified by NSF International, an organization that creates public health standards and certification processes for the water filter manufacturing business. For example, we have analyzed a large number of data points throughout the years, such as determining which NSF standard the filters are certified for (some standards cover only lead, likeNSF 372, while others also include agricultural and industrial toxins, likeNSF 401).
According to Rothman, “We also considered a brand’s track record and dependability, based on decades of water filter testing in our homes and laboratories.” Based on all of the testing and research, the following are the best under-sink water filters that you can purchase:
- The Aquasana 3-Stage Max Flow Claryum is the best overall under-sink water filter
- The Culligan EZ-Change is the best value under-sink water filter. The Multipure Aquaversa MP750 is the best compact under-sink water filter, while the Waterdrop Water Filtration System is the best reverse osmosis under-sink water filter.
Under-sink water filter with the best overall performance. Claryum 3-Stage Maximum Flow The Aquasana Corporation has established itself during the last quarter century as a world leader in water filtration. We give it top points for its revolutionary multi-filtration technology, which is NSF-certified to collect 77 pollutants including heavy metals, pesticides, medicines, and water treatment disinfectants. Its three-stage under-sink filter also gets high ratings from our engineers. GH Health, Beauty, Environment and Sustainability Lab director, Birnur Aral, Ph.D., has installed this Aquasana in her own house since it is one of the few filters available that has been certified to remove PFAS, which is a major factor for her decision.
Pre-filters, activated carbon, and catalytic carbon with ion exchange are some of the filter types available.

- Resistant to clogging
EZ-Change Under-Sink Water Filter is the best value available. While we haven’t tested this system, Culligan is a well-known company in water filtration with a solid track record based on prior Good Housekeeping recommendations. We recommend this system. Aside from having a low starting cost, replacement filters are also reasonably priced. A wide variety of pollutants, including lead, mercury, and cysts, have been verified by the Environmental Protection Agency, and it promises to eliminate chlorine taste and odor.
The EZ-Change can filter up to 500 gallons of water before it has to be replaced.
Granular activated carbon is the type of filter used.

Under-sink Reverse Osmosis Water Filter: Which Is the Best? The Reverse Osmosis Water Filtration System is a type of water filtration system. Despite the fact that it is not inexpensive, the Waterdrop under-sink water filter is hundreds of dollars less expensive than comparable reverse osmosis (RO) systems. This model’s tankless design, according to the manufacturer, reduces space while also being more water-efficient. In spite of the fact that we haven’t tested the unit, previous reviews on RO technology have shown its effectiveness in extracting pollutants.
This device’s clever design has impressed our engineers, who particularly enjoy its filter light indication on the faucet and smart monitoring panel, which provides information about the amount of TDS, or total dissolved solids, that is being filtered out of your water.
Reverse osmosis is the type of filter used.
- Exceptional filtration
- A compact, tankless design
- Intuitive controls
What are the many types of water filters available? The majority of household water filters are point-of-use, which means they’re intended to filter water from a single faucet or faucets. This article concentrates on under-sink filters, which are equipped with a dispenser that looks similar to a faucet. Our experts choose them because of their combination of functionality and a clean, space-saving design. Other kinds are as follows: Water filters in the shape of a carafe: These pitchers include an on-board filter that the water goes through, making them a low-cost, straightforward solution.
- Refrigerator water filters are used to purify the water in the refrigerator.
- These are often found at the top of the machine, though some manufacturers conceal them behind a trim plate at the base.
- Make certain that any replacement filter you purchase is at the very least certified to NSF Standard 42, which confirms that the filter’s physical components will not leach toxins into your water, and that it is a permitted filter according to the manufacturer’s specifications.
- By choosing this option, you may have the filter installed on your countertop and connected directly to your faucet.
- These filters, on the other hand, clog the sink deck and are incompatible with pull-down faucets.
- The majority of them allow you to choose between filtered and unfiltered water.
- Whole-house water filtration systems: Generally speaking, they are put at the home’s main water line, where they are intended to trap silt and other big particles that are typical in well water.
What are reverse osmosis water filters and how do they work?
On the other hand, the process of reverse osmosis (RO) removes pollutants from water by forcing it through a semi-permeable membrane under pressure.
Unfortunately, RO systems are typically costly and can waste a significant amount of water.
However, technological advancements continue to be made, including the development of smaller, tankless designs, such as the Waterdrop variant featured in this article.
What is the best way to find out what is in your drinking water?
That is helpful information, but dangerous substances can still enter your water after it leaves the utility, including through lead pipes in your house if your property was built before 1986.
That is why it is recommended that you test your water on a frequent basis.
The kit designed for municipal water costs $30, while the one built for private wells costs $35.
While every system is different, the majority of them have a filter housing that is installed on the inner wall of your sink cabinet.
There is a second connection that runs from the other end of the filter to the dispenser, which is located on the sink deck.
Capable do-it-yourselfers should be able to complete the process, but if you’re not confident in your abilities, it may be worthwhile to hire a plumber, especially if your water line needs to be adjusted.
