1. See how much pressure the filter can withstand and whether it can meet daily needs.

2, see if you want to use recoil or straight line.

3, look at the filter material, try to choose stainless steel material, not easy to rust and deform.

4. See whether the operation is convenient or not, and whether it is convenient for later replacement.

See if there is a good after-sales service system.

If your own pipeline well has a large free space, you can choose to install a filter behind the water meter or the valve to better protect it from damage. When connecting, use PPR union or pipe fittings with wires, which can effectively prevent water leakage.
