Machine is holding up and the filters hold a LOT!
We have two big cats. One of them a pure bred Siamese, which is supposed to be hypoallergenic. And we have a Morkie who never sheds even one hair. But the Siamese is a shredder. So we bought this for me because we all five of us sleep in the same room and same bed. It works great! Then we realized our Siamese was sneezing all day several times In a row, and smelling of litter... even in his ears. He's a flinger. Very enthusiastic about covering his poo. Litter dust was everywhere including up his nose and I could smelled it in his ears. Yikes! Our other cat didn't even bother to cover her business, so she wasn't being bothered at all. We put two and two together and I began to worry about his respiratory system. So guess where the air purifier is now. You guessed it. The litter boxes are in our laundry room, so that pricy purifier sits in that doorway and when we changed the filters we could easily tell this purifier and it's filter are doing their job very well. Sorry I don't have photos to show you the results. Maybe next time I change it, if I remember. Oh and after several tries, we did find a litter that is about 50 less dusty than the old one that said it was 99.9 % dust free. Haha. Joke is on us. They all day that and we just kept buying it because everybody else's does with no problem. My cat has sneezed one time since the change and the purifier is on duty. We are all much happier about that!

Right filter
This was the right filter for my mom’s air filtration. I gave it 4 stars just because I find the price very expensive.

Alen scrubs the air!
We have 2 British labs. They produce an amazing amount of airborne stuff - not dandruff. I purchased the Alen air cleaner about 2 years ago and the dust disappeared. The filters grab the material from the air. I vacuum the fleecy first filter weekly. I replace the main filter every few months. Every surface is noticeably much cleaner. I picked Alen based on Consumer Reports reviews
