I actually don't use the filter. I used the one it gave me, but it only lasted a month or so, then I tossed it. The waterer works fine without it.

Printed on the edge of the filter: "Change every 6 to 12 months - more often if the filter appears dirty." My HVAC person recommended every 6 months.

Replacement filters may be purchased direct from the manufacturer. Honestly we only need to replace them once a year as I clean the machine once a month with a vacuum/ brush and microfiber cloth. We've all had our filters (2-3 in each housed) for 4-5 years. I just bought a new one for another bedroom. Excellent air purifiers.

You can order them on Amazon. I normally keep my filters a bit longer than recommended, particularly in colder, dryer weather. My personal recommendation is to change the filters every 6-8 weeks in the colder months and once a month in any month without an 'r' in it. Always clean the bowl and motor and motor housing once a week with a small brush. It will keep the water from getting slimy.

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.

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.

It depends on how often you run the unit and how much dust/allergens it's filtering out of the air. If it is always running then generally the filter should be replaced every 6-8 months.

There is a permanent filter that can just be rinsed and an additional optional replaceable filter that can be used in front of the perma-filter. Not sure of the cost but replaceable filters need to be changed every 3-4 months....additional notes, this unit has a pretty loud fan if used on medium or high speed.

The hepa filter shouldn't have to be replaced for years. They can be washed out and reused, You might want to get one more to use when you rinse one (wet). I don't know where you can buy them . I will look on Amazon with make and model numbers.

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

You replace the whole unit. No filter here! After using this for 6 months, I switched to the Aquasana AQ-4105 which filters more stuff out and does have replaceable filters (but they cost about $20 more than the unit listed here every six months)

I have only had to change the filter once so far, and it is easy. You just remove the front cover, pull the old one out (have a trash bag handy because ours was gross and covered in dust). Then pop in the new one.

I find that changing that filter every 12 to 18 mos. is plenty to keep the water clean and fresh. As others have said, the company says annually, but they are making money more often that way. The filter I bought here is exactly the same except it has a lower price. What is not to love about that? (put masking tape on your filter and put the date your new one should be installed right on the filter casing.)

It comes with the filter when you buy it, but guess you could. I have yet to change it yet.

It comes with 2 filters that last about 6 months. You have to replace them with new ones ...bought on Amazon. We still love ours almost a year later.

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.

You have to buy a new one, but they last 18 months at least and are pretty inexpensive. You can take the filter out to clean it whenever the red indicator light on the air cleaner goes on. I just wipe it clean with a slightly damp rag. But after 18 months or so, the dirt gets inside the folds of the filter and the machine doesn't work as well as it could, so that's when you need the replacement filter. I've had this air cleaner since 2012 and have only bought one air filter replacement so far.
