Have brought this filter for four to five years.

Easy to install, convenient to have it come as a two pack.  Ours last 6 - 8 months span of life would vary with water and ice useage.

I have been using this filter on my 75 gallon tank with one turtle, and it has kept the water incredibly clean for over a year now.  I don't use the recommended filter loading in the manual, I used 2.5 liters of bio media in the bottom two baskets and the bottom half of the top basket, some carbon and purigen in media bags on top of the bio media in the top basket and the blue filter pad on top of that.  (don't use the white pads for turtle filtration, they clog way too fast)  With this media set up, it have literally run it non-stop (no cleaning) for the past year and 2 months.  Water is still crystal clear, and 0 ammonia 0 nitrites.  Flow is still good, although not as strong as when I first set it up.  It took just about a month to fully cycle the tank and has been stable since then.

I've purchased this filter 3-4 times over the past few years. It does a great job of keeping the cabin air clean. easy to install and a great price.

I have to review this little guy. I bought this coffee maker 4 years ago. It doesnt get as hot as I would like, but I just pour the half & half in the cup first.  It has been pretty flawless for 4 years. Recently the filter tore and I consider that to be my fault, since we put it in the dishwasher. Little issues to have $12 and 4 years later. I am considering buying one for my office as well as replacing the one at home. (since I don't know that I will find the filter online)

We've had this r/o filtering system for 5 years and it still works like a charm! I recommend buying the calcite filter from the Air, Water,& Ice company to add some minerals back into the water for better health and taste.

We got this filter to supplement one of the old round style ones. It works better than that one because of the three speeds as opposed to two and the better airflow pattern, but while the old round filter is still working fine, this one seems to have burned a wire in the motor after about 5 years. It still works, but the burned wiring smell defeats the purpose. Yes, we replaced the filters on schedule. We do have lots of dust, but that hasn't killed the old one. Certainly not bad, but not Five Star performance. It is easier to remove and replace the filter on this one.

Had it for 3+ years now with no problems, and it was a lot cheaper than the alternative canister filters.

Great filter.  I had one that died on me after many years, so this is a replacement.

This is a relatively simple filter. The install doesn't take long. I like the filtered water when it comes out, better than the city crap that comes in.

The disadvantage is they break about every two years. This is mainly because the sun comes through the window and degrades the plastic. It also doesn't help viewing the filter indicator. Past purchases have had a thicker plastic or some other issue with reading the indicator. My latest looks clearer.

It's good for what it does.

I expect this filter to last a decade or more, longer than the coffee maker in which it will be used.  I had one many years ago, but tore the screen while vigorously scrubbing residue from the surface.  Be cautious and the somewhat delicate screen will be sustained for many years.

I've been using these for years in my Bissell Powerclean Rewind. They help keep away bad odors that can develop with time. A dirty filter also cuts down on the ability of air to pass through, which results in more of a strain on the machine. So a few dollars on replacing filters can extend the life of the machine and these have been working great on my six-year-old machine.

I use these filters as fuel filters on a 37 year old sailboat.  I've used them since 1990 without problems.  They used to be readily available, though getting harder and harder to find.

I replaced the filter after over a year.  The old one was still getting out the chlorine fine and looked pretty good inside.  It is nice that you have a clear housing and can see the filter material.  This is a really first class filter.  I am opting to go for the 10k hours instead of every 6 months since it works so good and so long with my water.  I found it easy to open up the housing.  Used a toothbursh and soap to clean any gunk out of the housing and voila...ready to go.

This has been a really nice unit for the last several months. My water stays nice and clear and does not smell. I never have any problems with it losing its prime. I am using it on 100G cichlid tank.  I would recommend this filter. In fact, I bought a second, smaller unit of the same brand for my other aquarium shortly after this purchase.

Five years later and it's still going strong.

These filter a do a nice job of catching foreign matter in the air. They also last for a nice period of time. I have a moderate anoout of contamination at my home. (Pet hair, dust from living on a dirt road etc. )
