It just depends on how often you use fan, I have been using mine since last October and they aren't dirty yet. love it

Depending on hours run and amount of particulates in the air, every 2-6 months. If you get one of these: G99 Air Filter Gage and install it properly (quite easy) it will tell you when to change filters. Pays for itself in the long run.

Depends on use. I replace mine every 6 months. But I also keep my hot tub very clean and wash filter every month.

I change it every 6-8 weeks and I buy them from Amazon. Since the water sits out for approximately a week (unlike our human water), it's a good idea to use the filters.

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

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 replace mine once a month. You could probably go a bit longer if you don't have hard water and if you clean the humidifier once a week as recommended. I do a thorough clean only once a month and replace the filter at that time since it gets all gunky from both the dust it sucks in and the hard water build-up.

You change it every three months. I purchased this after looking at others without filters. Totally good value .

Depends on frequency of use - I use mine daily but filter water 4-5 times a day. Monitor pH every 3-4 months to see if filter is still achieving your desired pH . If not, see if holding longer time produces more alkalinity. If not , time to change the filter. I typically change out my filter every 10-12onths. But this may vary according to the pH of your water.

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.

I change mine every 6 to 9 months. It greatly depends on how wet the conditions are, and how good the inside filter does. All depends on how bad the system enviroment is.

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

I change the filter twice a year. I could change it more because we have cats, but I don't. It's easy to change.

It depends on how soon your scale build up on the filter. I change mine once a month from November to April.

Depending on the amount of use, your filters should last 3-6 months easily. You can greatly extend the life of the filter by using a small hand vacuum or dust blower to clean the filter regularly.

Changing the filter depends on how often you use the coffee machine. We change ours about once every 18-24 months because we do not use the machine very much (about 2 - 3 times a month). You could also gauge the changing time by how the coffee tastes. If you make it the same every time and you notice it tastes a little different, you probably need to change the filter.
