what is the life expectancy of the filter?

I have had it for more than a couple of years-so long that I can't pin it down. It is on its second coffee pot. Looks kinda cruddy, but works great.

I've had this one for over 2 years and it's still working fine.A bit stained but that's it.

Small failure after almost 3 years. I have had one almost 3 years, and it's been through one move about 2 years ago. The little handle just broke - small piece of plastic broke off, but I can still pull it out if I'm careful. A bit stained like others have indicated.

The first one we bought wsd thicker and lasted quite a few years.... over 7 years if I recall. This one is thinner but it holding up well. We do not put it in the dishwasher but only rinse under hot water; this may give it longer life.

From amazon I think I've read 1 year, from another website that sells the same filter I've read 1-2 I guess it depends how much you use it. Hope this helps!

I bought a spare filter with it in December 2012 but have yet to use it. Note that I use the device daily n live in a especially polluted place.

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

The life of the Hepa filter is 12 month and the life of the pre-filter is 6 months.

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.

I don't know. Depends how much you use it but you can generally tell when it's not filtering well. Water starts tasting like its right out of faucet. We have 3 - 5 people in house with quite a bit of use and it usually lasts about 2 yrs We've used that particular filter for more than 30 yrs. like it the best. Does great job. Lasts longer than most

ROI using "permanent" filter is 4 years. If you're worried about the environment, manufacturing waste an pollution exceed that of disposable filters. Disposable filters perform better. No filter is permanent, so over the life of the product you'll keep buying metal filters.

I am not sure, but they have lasted us about the same time as the original filter supplied by the MFG, about 6 months. We are a family of two.

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.

Manufacturer says 1 yr. I doubt if we have to replace ours at 1 yr, just vacuum the pre filter monthly. That will make a big difference on how long the filter lasts.

That's about it... The one that came with the cleaner lasted about that long as well.. After average use of once a week and occasional cleaning of the filter, I replace them in 10-12 months. If you have pets, more often probably!!

I have used these filters for the past 1 1/2 years without any problems. Sorry you encountered a problem.

I used mine for 12 months before replacing. Municipal tap water in Southern California is not a hazard, so my filter life may be unusual.

"dispose of filter after 40 hours of use or 30 days, whichever is first" - http://multimedia.3m.com/mws/mediawebserver?6666660Zjcf6lVs6EVs6662M_COrrrrQ-&WT.m;c_id=www.3m.com/filterchange

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.

On the old models I changed every 30 days. This one, with filter A, says it will last 3-6 months. I haven't had this one long enough to know for sure.
