Judging by how filthy they are when I change them, these filters are really pulling in dust and particles in from the air. And they last a long time too.

Filter didn’t last as long as they said it would.

Have used this in my mother in laws assisted living apt. She swears by it. Before she always felt she had allergies and it was dusty. Since we bought her this we have kept her in new filters whenever it tells us.

great filter. Air is cleaner.

Good quality, received it fast. My old filter looked the same but it was full of dirt.

It works great Wish they were cheaper
