I check the filter after the winter heating season and at the end of summer. Depending on use, I change filters once or twice a year.

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.

I've been told once per year but I change mine twice a year since we are proned to allergies and asthma.

With this particular filter, we change it every three months, I hope this helps :)

The company that installed my new system said that this filter would last one year. But when they came out to do an inspection after one year, the guy said that I should have changed the filter earlier. I now change the filter every six months. So far, that seems to be about the right amount of time.

Generally, you should change your 1/2", 1" and 2" air filters every 30, 60, or 90 days; the 4", 5" and 6" air filters should be changed every 3 to 6 months, depending on your environment. Thanks, Jessica

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.

It depends on how much of the filter is covered. I change the filter before each time I use it.

Our shower is used about 2-3 times daily. Our area has extremely hard water so our filters only last about 3-4 months. I change them when my skin starts to dry out (severe eczema,) or it smells heavily of chlorine.

It depends on your use but I try to change once a year. I have gone much longer though and have not noticed any degradation in the taste of the water. The filters really make a difference.

I have gotten away with not changing it for about two months. BUT that required me to keep the unit dust - free and clean on the inside as well s the outside. It also depends on how often you' re using it. If you use it constantly. then you will have to plan on changing the filter every month for sure.

The only other reason to change more frequently is if microbial contamination is a concern, I put a UV light treatment unit following my RO system to help fix any problems encountered here. Now I have a UV light to change once per year and another filter to change once every 6 months in addition to RO filters and membrane service intervals.

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

When the filter needs changing....yes!!! It's gross. And, the filters don't last long!

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 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 change them a little longer that the recommended times. We use the filtered water only for cooking and related things. There are two time frames: One filter will last one year plus and the other two should be changed every 6 months. As I said we try to wait a little longer. Maybe 8 months for the two and 14- to 16 months on the one. It really depends on use and the quality of your water.

I change the filter for our pooch about once per month. Depends on how hard the water is where you live. If you use filtered water it should last much longer.

As I use only distilled water, I usually change my filter approx. every 3 - 4 months. Hope this is helpful to you.

There are three filters One permanent, two replaceable. You should "clean" and re-use the initial filter monthly depending on the work load. I haven't had this unit very long so I just take the front cover off and visually check the filter. The cover is very easy to remove & replace. The other two filters are expected to last around 18 months. They have to be replaced, not cleaned. When the cover is off there are a series of led lights telling you the condition of the filters. By the way, removal and replacement of the filters is really easy.
