150 GPD RO Membrane with Reverse Osmosis Membrane Housing Set, Reverse Osmosis Filter Replacement Kit, RO Membrane Housing Set for DIY RO Water System & Maple Syrup Reverse Osmosis System

Works great

This membrane is perfect for my setup. It runs fast enough that the storage tank never empties. The membrane is well made and economically priced.

Works well, fits my RO unit and with the other filters and DI tds is 0 coming out of the last stage

Eccelent 400 gpd membrane. Used to make a diy water purifier to fill the tank on my rv. Many rv sites have nasty well water just like at my house and this makes 10ppm beautiful water from 500ppm well water. Using booster pump I achieved 12 gph at 75 psi and 10 gph at 65 psi, punky diaphragm pump leaks at anything over 70 unfortunately. Not exactly 400 gpd but at 100 psi it probably would do it. Plan to make another unit with 4 membranes soon for a whole house system with a reservoir tank. This is spot free water that can be used to rinse windows or vehicles and leaves no residue when it dries, those with well water will understand.

smaller than previous one but is working

Exactly what I was expecting

Used it to replace the ro membrane in Ispring system. Fit in perfectly and works great!

Exactly what I needed. Installed fine and our water is flowing well after the old one got clogged.

Follow directions and these work great. My ppm went from 650 to 20 after install. Great price and performing as advertised.

Funciona muy bien! Hay que tener paciencia ya que el agua de desecho será según por la calidad de agua de tu localidad.

I bought these for concentrating my sap for making maple syrup. While assembling one of the fittings broke so I contacted the company thru Amazon. They were great and gave me a few suggestions of how to make do in the short term and sent me a replacement fitting along with spares for all three membrane housings I bought. Although I haven’t had a chance to run sap thru them I was able to flush the membranes and purify water. My well generally has a hardness in the high 600ppm and on a single pass it was able to bring it down to 2ppm which is amazing. Te brand name wasn’t one I knew of or saw much about but so far I am very happy with the company and the product. I will definitely consider them for future projects.

bon débit. 75 GPD comme indiqué

The RO membranes themselves are working as intended, very happy with them. My relatively minor complaint is that the push to connect fittings that come with the kit are very finicky, and tend to leak. I would recommend giving yourself plenty of slack when attaching the tubing, especially if you are hooking up multiple membranes in a series, and make sure there is no tensions or torque on the fittings. Also the fittings are compatible with John Guest or Sharkbite push to connect fittings, which I founder were far more reliable and easier to use.
