Self-cleaning water filter FHPR12-3V with particle discharge faucet. Central supply filters FHPR12-3V are intended for filtering the water of the entire house. They are usually equipped with a 10” solid particle filter made of multipurpose polypropylene mesh from Aqua Filter (USA). The large cross section of the filters (1/2″ to 3/4″) favors a large water supply while their increased resistance to high pressure allows them to be installed in almost every home. Before buying them, make sure you have access to the central pipe for their installation, it would be a good idea to contact a professional plumber.
