Fit perfect, actually last 3/4 - 1 year. This air cleaner top notch for me in all respects from construction to packaging to operation and app provided. Highly recommended for serious filtration.

the filter is about 2.5x more than a Levoit core 300 replacement odor filter. I've tried multiple Levoit odor removal air filters, both from amazon and off the shelf in retail stores. They all worked less than a 24 solid hours for effective odor removal. There filters last several months running non-stop with the same pet odors that killed the Levoit in under a day. They also are ACTUALLY HEPA level filters and can remove smoke and soot from candles which the Levoit core 300 cannot do (because it is not actually HEPA despite be sold as such)Ever extra penny spent on the Alen BreatheSmart 45i and it's filters is money WELL spent unlike the Levoit which felt like I was just throwing money away.

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!

Great filter for our Alen device.

Does what a filter should. Quite pricey for such a small filter

I sometime buy cheaper parts, even for other air purifiers we have. But I have found the Allen Air filters are much higher quality than their knock off counterparts. These have an activated charcoal layer and the cheap ones don’t

Ordered filter for our air purifier, excellent product, exactly what we needed. Arrived in 2 days, perfect timing.

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

It is fine and as expected, but wondering why it was thinner than same model I picked up in the States. It is an Alen filter so I trust not short changed, just seemed odd.
