If you want to improve the taste and the purity of your tap water without cluttering your countertop or attaching a bulky appendage to your faucet, an under-sink water filter may be the answer.
In addition to being out of sight and generally improving the taste of your water, many under-sink water filters can remove worrisome contaminants. All of the under-sink filters currently in our ratings are certified to reduce chlorine, which can affect taste and smell, as well as lead. Most of the under-sink filters in our ratings also remove PFAS, so-called forever chemicals that have been linked to numerous health concerns, including cancer, thyroid disease, liver damage, and immune system disorders.
You can buy under-sink water filters at major retailers and independent dealers. They require installation and space under the sink, meaning they have a higher initial cost compared with faucet-mounted filters or water filter pitchers.
