way more flow than the Ultra Low Pressure Membranes

This membrane produces a lot more water than my conventional 40/40 that requires 60psi to just push through the membrane. If I put a booster pump on my ultra low pressure membrane, it still doesn't produce as much pure water as the no pressure membrane sold by Reach It. I am bout to purchase another for my other system. I use it in an area that has 150-250 ppm and have had it for two seasons cleaning 100-200 windows a day during our 9 month season. it is still producing clean water. Great upgrade for the original reach it system!

Definitely would buy again

Great membrane

I love this ro membrane. Great flow and gets at least 90% rejection.

David Carter
Very good flow.

I'm really happy with this membrane. I built my own filter with a 4040 housing from aliexpress and it works great! I get about 1ppm tds and then polish it afterwards with a DI Filter. A pump is needed if the water pressure is low.

I’ve had the wash-it pro for about six years it has always been reliable and efficient in use and service. We have had no issues whatsoever when I heard about an improved membrane I was excised to try it since it was time to change mine. TDS out of the ro is now between 1-5 ppm also changed to the atomic resin in the di to take tds down to zero. I’m using a dual tds meter in line so we can have access to the reading of both ro and di. Well Pleased
If you’re not using pure water you’re not cleaning
