How often do you need to replace the filter?

It mainly depends on how dirty is the air in your place. I replaced mine (the main expensive filter) after 3 years. But I think I could easily have stretch out to 4+ yrs. As far as the outer dust filter, I replace it annually or just wash and use. There was no instructions on that.

Usually every 6 months or so depending on usage. The machine will tell you when the filter needs changing

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.)

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.

You should clean the filter once /Month in covered pool. Probably every two years it will need replacement

Membrane every 2 years. Filters need to be changed more often--according to the amount of use.

I've found that vacuuming the filter and cleaning extends the life of the filter, buy you'll eventually have to replace the filter

Printed on the edge of the filter: "Change every 6 to 12 months - more often if the filter appears dirty." My HVAC person recommended every 6 months.

The filter should be replaced at least one a month or sooner depending on where the water bowl is placed. Mine is outside and the sunlight will cause algie growth and you have to clean the entire setup every two weeks. If it stays in the house once a month should be fine.

Clean the filter and then clean it at least every 30 days after that. Filter is located at the top and slides in and out (pul;l up to remove).

I have a 2000 sq ft home and don't use the forced air much, maybe 1 hour or so a day. I change mine every 3-4 months. Please see the answer from the filter salesman in reviews.

Bag and filter replacement will depend on the user's lifestyle. If you have children and/or pets and you vacuum daily, you will probably need to replace your bag every couple weeks. No kids or pets means replacement at two months.

I just estimate how many times I fill a day, which means for me, about every 6 months. This is based on the manufacturers recommendation for length of filter use.

There is a pre-filter that you have to change. There is an indicator to tell you when to change filters. How often depends on what setting you run. I run mine at medium 24/7, high for 1 hour after vacuuming. I change filters about every1 1/2 - 2 months. They're not expensive.

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.
