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.

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.

We use a lot of RO water! So we are changing filters every 6 months. We have well water. Comes out well over 500ppm of solids. Not good. After RO we're under 50ppm which is akin to Spring Water. We cook with it and give to our pack of dogs and cats. Thanks!

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.

Under kitchen sink reverse osmosis filter system - fit and worked fine - good value.

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.

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

The filter arrived with 2 broken nipples. The nipple has 2 O-rings and the nipples were smashed into the filter.

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.
