On average, how often do these filters need to be replaced?

That is going to depend on how much crud is in your water. With multiple cats our fountain is cleaned twice a week and the filter rinsed at each cleaning BUT the filter has been in well over 2 months now and is still working like its supposed to.

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.

I have had mine for a little over a year with no wear and tear. I wouldn't be surprised if the filter lasts for another 2 years. I put it through its paces, using it every other day for a few mins and for extended periods while cleaning once a month.

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.

and usage...if you run it 24/7. I would change every three or four months. Some folks just vacuum the filters. I'm goona try it.)

Replacement filters may be purchased direct from the manufacturer. Honestly we only need to replace them once a year as I clean the machine once a month with a vacuum/ brush and microfiber cloth. We've all had our filters (2-3 in each housed) for 4-5 years. I just bought a new one for another bedroom. Excellent air purifiers.

It's three filters that are replaced every six months. All three are used together. They come in a very compact container and are very easy to install and remove. I hope this is helpful information.

I only needed to replace mine at most, once a month. I would say it really depends on if you leave the filter on when you feed your fish. By turning it off during feeding, I could sometimes go 2-3 months before changing it.

I haven't had any problems with mine since I put it in. Mine been in for at least four months now, my old filter in had to clean it every month and half.

Directions say one filter is rel\placed at 6 months and second is replaced at one year. Sorry, I do not remember which gets replaced at which time frame.

I would say it depends on the conditions at your home. We live up in the mountains where it is very dusty, so we check it at least once a month. We'll change it based on the amount of dust on the filter paper. We can generally go a couple of months before having to change it out.

I think it's normal. I know for sure that filters need to be replaced every two months.

I think they officially want you to replace them every 6 months but I usually replace them around once a year. It depends on your usage. I have it hooked up to a below counter ice maker & also a drinking water dispenser above counter. When the water starts running slow on the dispenser I replace the filter.

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 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.

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 have been using these filters for some time now and never any issues, these filters seem to do a very good job at catching fine dust and dog dander. I do change mine more often than the manufacturer recommendation, I do so every 2-3 weeks just to make sure that my system is not working harder to keep up.
