Says $6.50 per count so this should be a total of 4 but only received 2, so this is misleading, very unhappy with this purchase

I bought this for filtering cat litter oder. The filter fits and filter particles. The paper filter is very similar to the manufacturer filter but the carbon filter is much thinner (1/3 the size roughly). The carbon filter is what filets oder which means you need 3 filters to filter the same oder as one manufacturer filter. This means the manufacturer is cheaper than this knock off if oder control is the main goal. As others said the replacement filter causes the fan light to go red quickly. I noticed it took less than a month. Overall the manufacturer version works about 4 months for oder control and this version is 6 weeks roughly

They look right and they fit right. And from the reviews, I thought they would WORK right too. They don't. They are completely inferior to the original filters; they don't absorb odors anywhere near as well as the original filters. I wouldn't be surprised if they didn't have any actual charcoal at all.

After reading the mixed reviews I decided to still give this a shot, but they do not fit. Yes you could force it closed, but that could change the efficiency. Plus with light handling the outer white filter began to separate from the black portion of the filter. 1 star for pricing but that’s it.

These things are cheap for a reason. They constantly go from red to blue and back without cooking or burning incense, never happened with the factory filters. Also, it takes so long for it to go back to blue after cooking something. Regrettable purchase.

WASTE of Money the reviews state 411 I have a 511 and as you can see they don’t fit the description is incorrect and they will not let me return them very disappointed.

Returned filters for Blue Pure Air 311 and 411 because did not fit wasted my time because Amazon did not check if product works.

nicht so effizient wie das original von blue air

The black sponge created a lot of tiny black sediments everywhere between the grooves of the white paper. The size is too large as you can see from the photos. General feeling of lower quality product. I guess this is why it's cheaper.
