BW-4040 Osmosis Membrane High Performance Commercial Industrial,BW-4040 Ro Filters for Desalination,4"x40" High Salt Rejection,Energy Efficient, Reverse Osmosis Membrane Industry (2400GPD)

Great ! Exactly what I needed .it Works

Excellent product

Purchased in December, installed January 1st. Fully Clogged by 23 March (3 months later (9,000 gallons)). I have multiple pre-filters, and the membranes I had before this one lasted much longer (1 year, 36,000 gallons). Now I am buying new membranes again, but a different brand than this. As they say, you get what you pay for.

There were no items in the package that were missing or damaged. Works really well, but my whole house water filtration system is lackluster. You'll want something like this if you're off grid, or living on an island in the middle of the ocean, lol.

This is a good 4040 sized commercial reverse osmosis membrane. These are good for removing the majority of dissolved solids, sediment, and bacteria/viruses from water at up to 2600 gallons per day. This particular membrane is also meant for desalinization, making it appropriate for making ocean water potable. The membrane appears to be well made and I have confirmed that it fits in a standard 40 inch membrane housing. For the quality and the price I find it to be a fantastic value.

I am delightfully surprised how well this membrane separates the detritus and salt from the water. The membrane allows a food flow of water without restricting the filtering process

I got this as a replacement membrane for my 2400 GPD whole-house RO system. It looks just like the membrane I have in it now, so...pretty sure it's going to work! And the price...what a deal. You'll need a 4-40 housing for this, btw. Definitely a step up in RO performance from the smaller less commercially oriented systems. 5 stars.
