The filter is equipped with 1-inch inlet and outlet openings, with a head made of polyethylene material, equipped with an air release valve and a pointed head for sun protection. It withstands temperatures from 5 to 55 degrees Celsius and pressure up to 10 bar. In case of low pressure, a pump can be installed after the tank and before the filter. The filters are changed collectively (set) every three months. Note that the filter contains a pressure gauge. This gauge has two main functions: the first is to measure the water pressure inside the filter, and the second is to indicate when to change the filter cartridges in case of clogging when the gauge pressure is zero. This filter works to purify water.
