4021 RO membranes for FLOW RED/GOLD

Great filters, but take care of them!

These filters remove about 90% of the solids and have a good flow rate. But after replacing them twice, I have learned that you need to do these 2 things to make them last longer: 1). Flush them after each use 2). Change the carbon and sediment filter regularly. I have let these 2 things go and believe me, these filters will need replacement sooner than expectd But keep them maintained and you’ll be very happy with them!

Easy to replace. Good waterflow and efficiency.
