Water filters can and will fit most any faucet. With a few household tools and some minimal knowledge of plumbing and adapters, you can install one on your faucets and purify the water coming from your tap. There are a couple of popular water filter types in most grocery or retail stores. Choose one that has affordable and readily-available replacement cartridges.
Determine what the faucet has for internal or external hardware at the outlet. Unscrew the drop-down outlet, if present, using the channel locks or pliers. If there is no drop-down present, determine whether there are internal threads in the inside of the outlet of the faucet.
Screw the base onto the faucet head or adapter tightly.
