Good price and got them fast.

We have cats and kids that go in and out all the time, and we are always coming and going ourselves. lots of dust and dander. So, we have 3 air purifiers running constantly. I ONLY use these filters in my purifiers. They are the BEST! and keep the dust and odors to a minimum :)

Correct fit and lasts a good amount of time

Good filter if you have prime even better free shipping .

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.

Pricey but will purchase again.

So super easy to change filter. Love it. Will buy again

I tried to use an aftermarket part from a different supplier and they did not work. The case has a tiny limit switch at the bottom that must be depressed for the power to turn on. The aftermarket part had a cardboard case with a foam seal and not enough regidity to depress the switch. I returned those and ordered these original supplier parts. They worked perfectly when installed. These are the only parts I will order in the future. More expensive but they work.

I purchased these for my home because my father was coming to visit and I also suffer from bad allergies and sinus infections. These definitely helped keep dirt and animal hair at bay. Last about 6 months before needing to be replaced.

Air is fresh in bedroom
