Hamilton Beach TrueAir 04234G Replacement Carbon Filter 3 Pack

I'm now on my 2nd set of 3 of these Febreze air filters and I have to say they really, really work. I have to use an unscented paper cat litter for my kitty and it doesn't mask odors at all. I didn't realize just HOW effective these are until my my very last one quit working and I didn't order any more for about a week. Boy, could I smell the litter box....yuck! I think I keep mine in about 1.5 months before changing them. The indicators that come with the filters and show you when you need to replace the filter don't work...I've only had 1 work so far.

I gauge the effectiveness of any measure by the volume of my daughter's complaints when we walk in the front door and she has been markedly silent about cat-smell recently. I have also been impressed by the decrease in the "welcome home!" odor. Pet owners, you know what I mean.

I was surprised how well this little air purifier works. It is in a bedroom we use for the two cats. It does a pretty good job of keeping the air fresh. I will continue to use this product.
