How long on average will these filters last assuming normal residential use?

We calculated we would replace our (2) 7" filters every 12 months for 2 people/ 2 pet household.

I change the filters yearly or the 2400 gal interval per pair of filters. This the recommended filter change by thy manufacture.

When I initally bought my "big" setup, I read that you should replace them once a year or max 1000 gallons. I replaced mine at the one year mark. If I were you though, I would order directly from propur. The customer service beats the other retailers. And by the way, im skeptical that these filters actually filter out flouride. Do your research

Filtering large particals, until water doesn't flow though anymore. But as long as you occasionally scrub the filter that's about, forever. Fluoride ions on the other hand are only filtered for 6-8 months because those are removed by the fluoride bonding with a chemical inside the filter, so once the chemical is saturated fluoride will begin to flow though again.

They say a year. I found that to be true although around maybe 10 months or so they started looking pretty dirty. I cleaned them (scrubbed them w/green pad - they looked almost like new again) but I replaced them around 12 months. They kept the water tasting good the whole time.

I can't answer that question. I have the filter in and on a daily use it lasts approx 3 months for me. I drink alot of water so it is active all day.

Depends on how often you run the machine...I run mine about 12 hours per day and I change the filters about every 18 months.

I'd say the two-month time on each filter applies if you're using it a lot, say 5 liters a day. Otherwise, you can keep it for 3-4 months.

It mainly depends on how dirty is the air in your place. I replaced mine (the main expensive filter) after 3 years. But I think I could easily have stretch out to 4+ yrs. As far as the outer dust filter, I replace it annually or just wash and use. There was no instructions on that.

I have read on a reliable site, that the black filters will last indefinitely. However, they said if the filters are going to be stored for long periods of time, put them in a re-sealable plastic bag, so that the filters do not absorb any air born contaminates. Jim Imel

The pre-filters seem to last about 4-6 months. We have dogs and that may affect filter life, although they may be on an automatic countdown timer.

The filter lasts about 4 months. This is much longer than previous filters I have used. Also, it depends on how much water you use. I make coffee with mine and use it for drinking water.

The unit figures that out for you depending upon how you use it and at what speed. My filters seem to last about 9 months or so.

I've used these faucet filters before, and the manufacturers tend to be pretty optimistic about the life of the filter. Also, the two months quoted is really an estimate because it depends on the condition of your water and how much you use the filter. I haven't had mine long enough here in Florida to get an idea of how long it will last, but I'm pretty careful about only using it for drinking water. From my experience, I'd say a month on a filter is within the 'normal' range. Btw (and I'm not sure if it mentions this in the little manual), I've read that running hot or even warm water through them kills the filter prematurely. The good news is this one has made a huge improvement in the taste of my water, so I have to assume it's doing its job!

That depends on how dirty the air is in the home. Some people change the filter every 6-8 months, other people can go 8-12 months. At our house it depends on things like how dusty the outside air happens to be. When conditions are dry and windy there is more dust in the air. When we have construction going on inside there is more dust. I have changed ours anywhere from 6-9 months depending on the conditions.

The filter lasted approx. 6 months. It would all depend on the quality of your water. This one was used in an apt. setting with city water, so I thought is was well worth the money.

I think is based on time. The filters continue to work for some time after. I generally replace them whan the water flow slows down. depending on use, that can be 1 to 3 years.

Approx. every six to eight months, running it 8 hours a day in my bedroom. I live in the southwest, in a dry dusty environment, so it would probably last longer under less severe conditions. Also, I must clean the pre-filter at least once a week.

Also depends on how often you are running your system. In the mild Pacific Northwest, I probably use it 20% of the time I did in NC. Annually or more frequent if the filters look dirty.

I've had mine for two years & haven't replaced the filter yet. So, I don't know. It depends on how much you use it I guess.

I use this device a lot in my cleaning business so they only last about 2 to 3 weeks. I would guess several months with normal household use.
