The Best Filters for Your Drinking and Household Water Supply
The best water filters for homes to purify water depend on the filtration needs, convenience, and budget.
Quality water that is safe and clean is essential for healthy living. This is especially true now, after the train derailment in East Palestine, Ohio that left residents exposed to toxic chemicals in their water supplies. The exposure was deemed unsafe and led officials to evacuate everyone from their homes.
Although the United States has one of the best water supplies in the world, in-home water treatment provides the final barrier of protection at the tap or for the whole house, to prevent contaminants from being ingested. Contaminants can include heavy metals, viruses, and pathogenic bacteria like salmonella, e.Coli, lead, mercury, BPA, glyphosate, benzene, styrene, chloroform, arsenic, petroleum products, and more. Water that needs filtration may taste unappealing, look discolored, smell bad, or appear with concerns like rust on kitchen or bath fixtures or buildup on pipes. Water filters also provide an alternative to buying wasteful single-use plastic water bottles.
With so many different types of water filtration options available, it can be confusing to know which one is best for a specific home’s situation. There are water filter pitchers, units that connect to an individual fixture on the counter or under a sink, and others that serve an entire home’s water supply. Also, keep in mind that filters have different technologies that are effective against certain contaminants, so getting water tested to know its needs is helpful before purchasing a water filter. Read on to learn more about some of the best water filter products that you will want to consider adding to your home to enjoy fresh, clean water.
1. PUR PLUS Faucet Mount Water Filtration System FM3700
This faucet-mounted carbon filter uses Mineral Core technology to filter out contaminants and improve the taste of drinking water. Reviewers say that it is easy to install and use, as it leads to noticeably cleaner-tasting and strong-flowing water. Certified to reduce 70 contaminants including lead, mercury, and some pesticides, this product filters up to 100 gallons and lasts up to three months. Without any tools required, it mounts easily to most kitchen faucets to enjoy fresh water right from the tap.

2. Aquasana 3-Stage Max Flow Claryum Under Sink Water Filter System
Aquasana’s Claryum 3-Stage Max Flow filter transforms tap water for up to 6 months (or 800 gallons) into clean, great-tasting water. Although on the expensive side, this product is very effective and long-lasting. The filtration technology is tested and NSF/ANSI certified to reduce over 97 percent of chlorine and chloramines, 99 percent of lead, and 96 percent of PFOA/PFOS. It is also certified to reduce mercury, chlorine-resistant cysts, herbicides, pesticides, VOCs, pharmaceuticals, and more. In fact, it tackles 15 times more contaminants than the leading pitcher filter. A bonus is that these filters are sustainably designed with minimal disposable plastic parts for reduced plastic waste. And the filters are easy to replace–no need to disconnect the hose or water line. Keep in mind that this filter requires a ½-inch diameter hole in the countertop or sink to install.
3. APEC Water Systems ROES-50 Essence Series Top Tier 5-Stage Certified Ultra Safe Reverse Osmosis Drinking Water Filter System
This Amazon best seller is a highly efficient and quiet reverse osmosis filtration system designed to be placed under the sink. It comes with a separate tap for filtered water to separate drinking from tasks like washing hands and doing the dishes. This product uses five different stages of filtration to remove 99 percent of contaminants. It has a sediment filter, two stages of carbon filters, a reverse osmosis filter, and a coconut fiber filter. Installation is quick and easy, but specialized tools are required if there isn’t an existing hole drilled into the sink or counter. Filters should be changed at different intervals; the first three last six to 12 months and the others last two to four years.
4. Express Water Heavy Metal Whole House Water Filter

Express Water’s water filtration system is simple to install, and filter cartridges get replaced every six to 12 months.

5. iSpring CKC1 Countertop Water Filtration System
This countertop water filter is a good choice for those looking for a budget-friendly solution that does not require installing a whole filtration system. The stylish, compact design blends into any kitchen and works well in small spaces. It connects to the faucet without any drilling required. However, an adapter is needed for some faucets, which might make it look clunkier. The carbon block cartridge that needs to be placed every six months filters out 95 percent of chlorine, odors, sand, silt, sediment, and rust from drinking water. It has been tested by the Water Quality Association to meet NSF/ANSI standards.
6. Frizzlife Under Sink Water Filter System
As an Amazon’s Choice product, the Frizzlife Under Sink Water Filter System includes a two-stage high precise compound filter that reduces contaminants like lead, chlorine, and particulates while leaving in all essential minerals. Reviewers rave about the fresh taste and super easy installation. However, replacing cartridges can be tricky and is recommended after six to eight months. The good news is that only the core part of the filter cartridge gets replaced, so you won’t have to throw away the entire plastic part. And since it filters quickly and efficiently, it does not affect water flow speed.
