how often do you have to change the filter?

Every three to four months seems like a lot, they have a color diagram on how dark the filter should be before changing it. I have been changing the filter once a year according to instructions, but might not be enough with allergies.

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.

Yes, you'll need to change it every month or so. The meter indicator will tell you when to change it. Very easy to change & filters are not expensive

I replace the filter about every 9-10 months. It runs 24/7 on fan speed -2 except for those weeks when the weather is nice and we open the house. I wash the foam pre- filter every month

you have to replace filter once awhile. Depends on your air quality. I do it every 6 - 8 months. Just buy the matching homeimage filter on Amazon.

Filter needs to be changed every 6 months or so - but realistically, I haven't done that yet and it seems to still work well. I run the machine on automatic every morning.

The unit has a timer that reminds you to change the filter every 6 months. I changed the filter for the first time this month (I've only had my GermGuardian 6 months) but after I did I realized the filter wasn't all that dirty, probably could have easily been wiped off and would have lasted at least another 3 months. We have a large dog but live in Seattle where there's not a TON of dust in the air. We run it 24/7 on medium.

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.

When the filter needs to be changed, the water flow slows down. It all depends on how many contaminants are in your water. My water is pretty clean, so I only have to replace the filter every 6 months.

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

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

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.

It depends on how much waste your fish make and how much u feed them. But u can wash the filters out and use them 2 or 3 times before having to use a new one. But if you're like me and just use new ones i replace my filters about once per month. So i would say 12 times a year if you're always using new ones. Ohhh and if u do reuse them make sure u wash them with used tank water, u don't want to wash them with new water... Aka chlorinated water out of the sink... Theis will mess up you're good bacteria in your filter.

I change the black filters about every 3 months. The hepa filter about every year. But the hepa filter needs to be cleaned. I clean mine 3 times a year. use a soft brush and then by water. Do not use any soap, just water

The directions advise you to change the filter every 2-4 weeks, but I find I can go 2 months. (one cat household)

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.
