Work great! As an allergy sufferer I was worried whether or not they would perform as well as the “brand name” filter. Couldn’t be happier with the purchase!

Perfect fit. Why pay more?

Good product.

A customer wrote "Add said they are compatible with my machine, but filter light remains on, so not sure if it’ll damage it"The filter light is reset by holding the button down until it clears. Do the same for other filter lights.Perhaps it can be done from the app for 'i' models but I have never installed it since the basic operations work from the control panel.

When I started using them they smelled strong like motor oil and made the living room smell like it, which makes me worry that it isn’t safe to use. The BlueAir didn’t have that smell to them either, which is concerning. It makes me wonder if they didn’t use the right kind of charcoal or something.

Nice quality. It's cheaper than getting them delivered from the manufacturer. Will buy again

Very easy to install and they do the same job as the ones sold by Blueair.

great
