| Category: | Water Filtration Technology | |
| Description: | Household water filters generally fall into one of two categories: point-of-entry units, which treat water before it gets distributed throughout the house; and point-of-use units, which include countertop filters (e.g. filter pitchers), faucet filters, and under-the-sink units. Some filters use more than one kind of filtration technology. | |
