How often do you need to replace the filters?

I have had this canister for six months. Each time I empty the dirt, I use a soft brush to clean the filter. I have not cleaned the filter yet, but plan to this month.

I rinse dirt bin filter every time when emptying the dirt cup. You should be able hand wash motor filter as well.

It depends on how much stuff you have in the air (I have a lot!) but the recommendation is to replace the black filter every 3 months and the big white one annually.

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.

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.

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.

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.

I do not know what the manufacturer recommends but I do stained glass and use it about the same amount of time as you. I replace the filter about once a month.

The system manual recommends changing the pre and post filters every 6 months and the membrane every 1-2 years. I don't use a lot of water and my city water is very clear so I am planning to change all the elements every 5 years. Good luck

Really clean the filter or replace it. We need to clean the filter at least every two weeks of use.

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.

We replace ours about every 2-3 years. Our son works for a water improvement company and he told us every 2 years. Hope this helps

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.

Most of the filters say replace annually, bit it really depends upon your usage. I usually replace every other year and I haven't had issues with water quality...

I change the membrane once a year and the filters every six months. Works well for me.

I have city water so I replace mine every 60 days as recommended. If you have whole house water filtering, then every 90 to 120 days. It does make a difference .
