Consumer Reports Best Water Filter - A Few Choices
It is important to know what contaminants the water filter is designed to remove before you buy one. Some filters are only capable of removing a particular set of impurities like lead. Others can handle a greater range. If you aren't sure what you want removed from your water, you can consult your local water quality reports and research any potential contaminants.
Countertop: A countertop is a popular option for filtering large amounts without plumbing. Although it is less likely to block than faucet-mounted pitchers, the countertop can clog your countertops and cannot be used with pull-down or spray faucets. It also isn't recommended for people who are immunocompromised, as they could be exposed to germs if the water they drink doesn't pass through the filter.

Faucet-Mount - A faucet-mounted filter can be a great option for people who don’t want to do any plumbing work or have a hectic schedule. They attach directly to your sink, so they are easier to install than under-counter or pitcher models. These models are generally less expensive than those that come with an under-counter filter and include an indicator light to let you know when it is time for a new one.
The Pur Plus Faucet Mount Filter, which filters more than 70 contaminants (including lead and mercury), is a popular pick. The filter comes with a carbon block that improves taste and odor, too. It's a great choice for renters or those who don't have the time to do more extensive plumbing modifications.
