- Hydrotech Compatible Reverse Osmosis Replacement Filter Set With Membrane 33001068-25 GPD

It was a perfect replacement for my American ro system. Easy install no issues.

fit perfectly in my filter and i get the waterflow i expected, good value for money.

Met expectations. Works well with my system.

I may use a Gallon of RO a day. the Membrane. can last me 3-5 years, and about half that time for the other filters. Your Mileage May Differ. I change the filters when I can taste the water as RO should have a clean "no taste"

I would not buy product from them again I think it's a cheap knock off. The cotton filter was not wound string and the carbon filters left a lot of carbon particles in the water. The water taste was horrible like tap water. Had to get a wound string filter from eBay and toss the one it came with, this made the water somewhat bearable to drink. I don't think the other filters are doing their job as well as they should. Have to find authentic replacement filters.

So far so good, I now have good drinking water, just wish it came with a one way adapter instead of 2-3 way adapters for the top filter.

I have previously purchased this set of filters for my reverse osmosis unit, which I’ve had for more than 25 years. Has never disappointed me and always worked perfectly. I would recommend this to anyone who owns their own RO system.

This is a cheap knock off from China. I replaced the membrane and lubricated the rings. Still reading membrane failure. Testing the water with meter is same reading as from regular tap. I had to purchase the original Hydrotech membrane to replace this. Do not buy

Good product. Good price. Good fit.

The stems of these Hydrotech filters are not the same size as the Culligan original onesc even though they look alike. The stem of the yellow tube is simply too big to insert into the slot. Even if the other filters click into the slots, water spews out once water runs through the system.

Can't use it due to the black stuffs, made the tank of water useless.
