How long do these filters last or how can I tell?

I usually switch them when the filter gets dirty (usually on the inside) and/or loss in suction. Hope this helps

Well, the bad smell was during the first use. I don't think these are made by Bissell, but made for Bissell by a third party. So I don't think the filtering quality is up to snuff. I saw official Bissell filters at Home Depot. I'll probably just buy those next.

I haven't replaced the filter in either one (I have two). I have had them more than a year.

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.

Ditto Donna BUT I saw on their web site that you can vacuum the filter (usually 12 months from the time you started using it) and that the filter should last a total of about 2 years. Now we know why it was a Gold Box Deal when we bought them!

You would have to ask the manufacturer of the filters for that info.....I'm just a consumer :)

I can't tell you how long it lasts since I am still using it. Be sure and get the pre-filter which will keep most of the dirt off of this filter.

I got them here on amazon. You'd be surprised how long the filters last. I see 10 clue st a day on average and a filter will last me a out a month.

I work in the lab thats why i can check the quality of my water from this filter. In my community this filter can last for 4 years. By the way I have a pre filter connected to this unit. The life of the filter is subjective to the water quality and your usage. Take an optional water quality testing.

Honeywell tells me it will last from one to three years depending on how much you run machine. You should be able to tell because eventually the outside of the filter will turn sort of pale beige/yellow compared to the inside, which will still be white. You can also vacuum it to prolong life. Just use a soft brush and don't damage the paper folds.

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.

To the best of my knowledge, they cannot be washed. We've had ours for about 6 mos., and are about to consider changing. If your don't have a real serious dust problem, I'd say 6-7 months would be about the life of this filter.

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

Go to Monolithic website and read up on these filters. I believe they are good for 6-8 months with the cleaning and shaking then should be replaced.

The specs on Amazon really don't say, do they? However, pleated filters are generally expected to last 3 mo. vs. the other variety that looks like open fiberglass. Anyway, that's the time interval I change them out and they work fine. Of course, the dustiness of your environment will impact a lot. Suggest you inspect periodically. When they begin to look dirty, it's time to change.

Depends on your usage, how hard your water is and how often you clean it. If you maintain properly, it should last 3 to 6 months. Google how to clean a humidifier filter. Cleaning it is the key to its longevity.

About 3 weeks. I smell them everytime I change the water. It is obvious when the smell changes, change the filter.

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.
