APEC 90 GPD Complete Replacement Filter Set for ULTIMATE Series Alkaline Reverse Osmosis Water Systems (FILTER-MAX-PH) Water Filter

Very well made and good quailty filter set. Very easy to install using the wrenches that came with my ULTIMATE 90 6 Stage System. We have had the unit for over 3 years with no problems.

We have had our 6 stage RO system for 3 or 4 years now. We always have clean and healthy water that tastes great. The alkalizing step makes it taste better than bottled water! And I LOVE that I am not buying plastic bottles! We recently replaced all of the filters. We had a small flood, because I thought that I turned off the water, when in fact I did not. But all is well, and my husband and I can laugh at our handy skills. Other than that, the filters are fairly easy to replace. Prior to purchasing our APEC system, we rented a RO system. I am much happier with this system, and feel that it is more economical and better tasting. Customer service is great and even sent out a reminder to change filters when needed. Thank you!

I live in a tiny town of 100 in rural America, and without many resources available our water is very questionable. A few years ago I decided to install an APEC RO system to feel a little more comfortable with what I am drinking. I change the first 3 filters every 6 months, and every time I see the filth on the old filters I am thankful at how much garbage it filtered out for me (see pictures for what my nice white filter looks like after only 6 months!). After seeing how bad my water is I have started using the RO tap for cooking and everything, so my only regret is that I didn't get the quick dispense upgrade which would fill up my pots for cooking a lot quicker. Overall I am happy to feel safer and healthier with my drinking water now.

I recently purchased the Apec Water filters to replace with the yearly filter change. This year I changed all 6 since I have owned the filtration system for a few years now. Great product, easy to operate and service, plus the end product which is water, tastes great and is crystal clear.

During a remodel several years ago, I had the plumber add the additional 1/4 water line and valve. Drill the granite counter top and drill the drain line for the RO waste water. Once it was in it works great. With filters parts do where out and if you're DIY'er it should no trouble to update the filters. I did overlook these rings the second time i changed the RO filter and took some time to find the right stuff. Eventually found everything I needed and finished it up leak free.

We love our reverse osmosis filter. The new filters are easy to install. I was able to change them out while my wife was away and have her believe I had really worked hard to get it done, brownie points for an easy job!!

The water tasts better and it takes out the mineral deposit. After we started to use the filter the build up in our coffee maker and hot watter has gone away. It also gives us safe drinking and cooking water

Have been using the APEC system for a few years now. replacement filters fit flawlessly and instructions make it easy for anyone to replace themselves.

I purchased these filters to replace my old ones. Super easy to replace and they last a long time. I love this system. The water tastes great and it filters plenty of water for our daily use including cooking. I would highly recommend.

I bought this several months ago and finally installed it maybe two months ago. We have very acidic water (like PH 5.5), so our water tastes sour normally. With this kit our water tastes much more mild. Also great water flow. I didn't realize how ineffective the old kit was until I replaced it. It used to take several minutes to fill a nalgene bottle, but now it's like 20 seconds. The only negative I have to say is since I installed this kit (and this is the first time I replaced the RO bladder in over 10 years of owning the system) the unit sounds like a helicopter under our sink. Not sure if it did that before and I've forgotten, but it's a little distracting how loud it is.
