I cannot smell myself and depend on my house keeper to help me with that. Not more than a month is what we figured out.

About 3 to 4 weeks. Depends on how much you clean the litter box. I have 2 cats that use the litter box when it is cold outside.

The filters are typically replaced annually. The membrane should be replaced every 3-5 years. These figures are for typical municipal water conditions. Part# B000F5M6V6

We have used it daily since January. About 60 days. We have not had to replace any parts. Two extra filters were included with original box. We do clean the filter with the included brush after each use

I haven't change my carbon filters as of yet and the other filter the manufacture say's its good for a year. Which that to me remain to be seen.I say that only because I have only had my 2 unit up and run for 2 months on auto any have only shut them off to check the filters and they all look just fine.My units came package with 3 extra carbon filters.

The problem is that carbon filters provide a warm moist environment to grow bacteria so you pobably want to change them every 3 to 4 months. S.Chiples

I haven't yet had to replace the filter. I don't use it that much. My filter is a permanent filter and I just empty it in the trash when I use it.

Thanks for reminding me. Just checked out my carbon filter and it was filthy. No wonder I've been coughing and sneezing. Just ordered another combo pack through Amazon.

I generally change mine every 3-5 years, but it all depends on the level of pre-filtration, the level of chlorine passing through the membrane, the temperature of the water. I use a .5 or 1 Micron Carbon Block pre-filter and change it every 6 months. TFC Membranes have a very low tolerance for chlorine, so if you are not using a quality Carbon Block pre-filter, the membrane will not last as long.

ive had mine for around 6 mo n the hepa filter i may have replaced once but i have replaced the prefilter 2-3 times

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.

6 months for the carbon filters. One year for RO and DI. Based on my use rates.

Eventually the filter will need to be replaced. As long as you take care of it it last a long time.

The filter should be changed every 6 months if used continuously. HEPA filter traps very fine particles, down to 0.3 micro; and the carbon filter absorbs the small and other particles from the air. People are always surprised when they see the old one vs new one (and that's only the big particles trapped). The replacement filters are $20.

The prefilter is there to catch sediment before the water passes through the carbon filters. This prevents the carbon from getting clogged up prematurely, extending the life of the unit. We recommend replacing the prefilter cartridge at least every 3 months. Actual interval will depend on your incoming water quality.

The Fellowes filter comes with a HEPA + one carbon charcoal filter. The recommendation is to replace the HEPA filter every 12 months and a carbon filter every three months. So I bought 1 extra HEPA filter and 1 set of carbon filters (four in the box) to cover the next year or so. The Fellowes filter has indicators to let you know when to replace each filter.

I haven't noticed either way, I do use s charcoal filter at all times, replace it ever three months, but think I'm gonna switch to every 3 months

Carbon I would at once every couple months, my method with all filters and water parameters is if it's not broken, don't try to fix it. This filter is horrible though, both replacements leaked about 3 gallons of water on my carpet, spend an extra hundre and get a fluval 206
