Stainless Steel Water Filter System 0.01 Micron with Washable Filter Element, Ultrafiltration Water Purifier 1000L/H 4GPM

Todo esta bien, no me agradó que no hay repuestos del filtro o no dan respuesta sobre el tema...

Didn't produce near the quoted flows.

This is a pretty good value for this type of 2nd generation ultrafiltration filter with the PVDF washable filaments. The ones that look like this are all pretty much the same. Your flow rate will depend on the input pressure and how fouled the membrane is. At 30 PSI, my flow rate is about 1.8 GPM. This is a good option if you have well water with very fine clay silt. Be aware that the reported thread size is misleading (probably unintentionally). While technically accurate that the DN20 20mm thread size is about 3/4", it's certainly not compatible with 3/4" NPT fittings. It's closer to 1/2" NPT, but those won't work either. DN20 is a metric size that is the same as G1/2 or BSP 1/2 inch. An adapter will be needed to connect to NPT fittings although I was able to successfully use a 1/2" NPS braided hose with rubber washer. A PEX swivel fitting with rubber base would not seal.
