How long do the filters last?

The reverse osmosis filter is supposed to last 5 years. The prefilters (in the 3 vertical cylinders) need to be replaced every 6 months.

I replaced mine at about 10 months. My well water contains about 450PPM. I would estimate I use around 40-50 gallons of RO water per week.

I contacted the manufacturer in Vista, CA with the same question. The answer I received is that the life of the filters depends on the water. I live in Yuma, AZ where the water is very hard and full of minerals. I was told to change the filter elements every year. They aren't that expensive and it would be worth it to me to change them out yearly.

Living on the east coast of Florida they last about nine months of heavy use. I only use two filters at a time so take that into account. Hope this helps. Nancy

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 just purchased this item so don't know how long it will last. The instruction manual states the filter should last 6 to 9 months. I would guess that depends on usage. I use mine about 2 to 3 times a week and for a short period of time.

I can't say how many gallons before its done but these filters with moderate usage last upto a year. I use mine for my koi pond and water for my dogs. I test the water often because I need to keep the chemicals out of my koi water and this is my second filter. The first one last one year give or take a month. I expect the second to last the same.

I have been using these filters for the f]past 5 years. From information received from the company's website, I have always understood them to last 12 months.

I believe one should last about 6 months, but I don't have any pets. What I usually do is run the filter under some water and give it a good clean and its like new.

I replace mine every three of four months. Could go longer, but we have a central well in our neighborhood and often get sediment in the lines that has to be flushed out (causing my filter to clog). Generally, activated charcoal filters should last 4-5 months.

I am not sure how long I have had mine, but never replaced filters in the past. I wash them after each use. I purchased this one because I changed coffee makers.

There is no expiration date on the filters. With two people using the filtered water, mine typically lasts a year. The water flow will slowly decrease noticeably and after a couple weeks will actually stop so have another on hand when it begins to decrease.

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.

We recommend changing the filter every 6 to 8 months. However, the filter life will depend upon the environment in which it is used.

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 have never had one go bad yet. I usually replace them at five years, or when Sawyer invents a smaller filter. I think the filters are guaranteed to filter a million gallons. I will never reach that threshold.

According to the manufactures info it is 6 months. We only just installed ours this month and really wont know until the water changes taste. In my experience with filters, most of the time you can get more filtered water than the manufacturer states but that depends on the area you live in (the chemicals in the water).

It depends on how much water you run through them and how clean the water is. For filtering tap water they should last for several years and the elements can be scrubbed if they get plugged up with sediment - i hope this helps

I've only had mine for 2months..I'm not sure,but other reviewers have said they have vacuumed or lightly brushed the filter to clean.
