Not sure of the correct answer to your question but I wash the one that I can and the other one i clean it by high-pressure air I replaced it because the one that I keep blowing out with air was to the point where it could not be cleaned any further so I replaced all four filters and hopes to keep my vacuum in better shape I have had the vacuum cleaner for over three years and this is the first time I replace the filters

I had mine for several years before I bought a new one. I just cleaned the old one regularly

I changed mine after two years..it kinda depends how it looks after two years. The sponge filter that surrounds the filter is delicate. It holds up to gentle washing for a while.

I think these filters should be changed out every 6 months. Just because of how much filth they pick up from vacuuming.

I change when it gets too old, worn and tear. But I would rather change fliters every 6 months to a year. It depends. I have 4 cats and it gets to use a lot. So you know it depends on what your situation is.

Of course depending on how often you go by it, I've had to change them about every 8 weeks so far.

according to use, we use ours often so we change bout every 2 months, but it no hassle. Listen when we are on vacation or a business trip, we look at each other and say "I will be so glad to get home to my bathroom". The best part of my $15,000 bathroom remodel. Dont hesitate BUY IT!

It depends on the weather The hotter it gets the more often it needs to be changed When it is in the 70 and 80 30 days is just fine but when it gets above 90 for a extended time change every 15 to 20 days.

I change mine every 6 months. I have pets. You may be able to go longer if you don't have pets.

It depends on how often you clean your razor, but there is a light that blinks when it is time to change the cleaner. I usually have to change mine about every 4-6 weeks.

I heard from a professional that they should be changed annually, sonthey probably last a bit longer...

I think they recommend once a month. It depends on how frequently you use it.

There is no definitive way to decide when your oil needs changing. Generally...every 7-10 uses. I refrigerate my oil (peanut), and depending on the visible "cloudiness" of the oil usually change it out every 8-10 uses.

We recommend changing the filter every 6 to 8 months. However, the filter life will depend upon the environment in which it is used.

from my research, it is recommended to change monthly. To be safe, you may want to visit the manufacturer website.

This filter is intended to be changed every 12 to 24 months. It is recommended that the average household change it every 12 months for optimal performance and 18 months for optimal value.

I have changed mine about once every 3 months however I'm using the same fragrance on each pad per fan but I don't run mine every day, probably about 3-4 days a week for about 8hrs each time. If the pad starts getting dirty then change more often because the fan is pulling up air through the bottom and if pad is dirty the fan doesn't work as well. If you are refilling the same fragrance oil onto pad every 15-30 days then you probably will have to change pads during a 90 - 120 day period because after awhile the pad gets sticky. I use pure essential oils since they last longer and have a more pure scent. Love my fans!

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.

I've been changing mine every two months. Honestly not sure how often they are supposed to be changed.

It depends on how hard your water is & how often you shower. I would recommend every 6 months, & not less than annually under normal water conditions.

I change mine every 90 days or so. I can usually tell when it is time by the taste of the coffee. We drink a lot of coffee.
