PUR water filters are designed to fit on most standard kitchen and bathroom faucets. There are a few exceptions, so it's always best to check the compatibility list on the PUR website before purchasing a filter.
PUR faucet filters use a universal adapter that fits on most faucets, but there are a few exceptions. The adapter may not fit on faucets with recessed aerators or those with non-standard threading. If you're not sure whether your faucet is compatible, you can check the compatibility list on the PUR website.
If your faucet is compatible with a PUR faucet filter, you'll need to install the adapter that comes with the filter. The adapter screws onto the end of the faucet and the filter snaps onto the adapter. Once the filter is in place, you can start using filtered water by turning on the water and selecting the filtered water option on the faucet.
