It takes a bit of a system to make it work
I run this in a whole house RO system and it brings the ppm from 1000 to 20-30 ppm. No water spots on the shower glass and no water spots on washed cars with no drying. Great filter

Good initial rejection and good flow
Just replaced Hydronix BW-4040 membrane that went bad after about 2 years and 5 months. https://www.amazon.com/gp/customer-reviews/R16FWRWQBFE8GZ/ref=cm_cr_dp_d_rvw_ttl?ie=UTF8&ASIN=B01CFOGPXY Initial rejection rate is on par with the Hydronix, but the flow rate is much better. Both are rated at 2400 gal per day, but I could never get more than 1 gpm with Hydronix. This one is flowing at 1.6 gpm so far. Let see how long this one will last. Using in on my whole house well water RO filtration system. Fast delivery, good flow and good rejection rate.

Not worth the lower price
TDS levels on output were less than stellar. This was saturated and sat for 24 hours before installing on my existing system. I was adding an RO in parallel with my current to increase overall production. Smoked a brand new DI resin. I cut the DI out of the loop and flushed the RO membrane. Installed new DI resin and was getting a TDS of 15 - 19 from 450-500 pre filters water. Cut this RO membrane out of the loop and flushed and re tested with a TDS of 0 - 1 If you’re shooting for 15-30 TDS for your application this membrane is fine. Sadly it will not cut it for my window cleaning business. I’ll stick to Xero or Tucker for my membranes.

Installed in minutes
The product arrived at an acceptable time, was the correct product and was installed in a matter of minutes. This corrected the gallons per minute regeneration.

very bad, don't buy
I bought this filter on October 2020, and it was supposed to last at least one year, but after only 3 months it made the water taste horrible. I don't recommend it at all. Buyers beware!!!

Our RO filtration system has 5 micron and 1 micron pre-filters. Tried this product to save a few hundred $$ over locally available competitive cartridges ... this was definitely not worth it. This filter clogged (no idea how with the pre-filter protection) in less than 2 months when it should have lasted a year vs. higher quality / higher priced alternates. Communication with vendor was a significant challenge. You get what you pay for - sadly.
