Countertop filtration devices are the most popular categories of water filtration products because their initial connection and filter replacement can be done in less than 2 minutes.

Before purchasing the product, make sure that your faucet has a detachable nozzle system or has a thread where the divert valve of the system can be installed, allowing you to switch between filtered and direct water from the faucet. In most newer faucet devices that have a shower system, connection is not possible because they do not have a thread.
