When you install this, the Blueair actually turns on and off automatically. It makes the unit smarter. Good buy worth the money.

Product is quiet effective

Excellent product. after cooking , it took just 5 minutes to clean out smell in my 500sqf room. My blueair pro M 's air flow keep very strong even using this heavier filter. my all family are happy. Just I hope this cleaning quality of filter continue 100% at least 6 month. I just started to use so let's see how it would be.

The filters are amazing. Shipped in the retail box individually when I ordered replacements. The retail box does not fully protect it when shipped. No hate to the product at all. It’s amazing. Just it should ship with some protection.

These filters smelled horrible on arrival! I’ve used these filters for years and never had a problem before. I had to put my old filters back on and that fixed the problem. We just vacuumed them off to reuse. I am chemically sensitive and these are supposed to absorb VOCs, which they have done well with in the past... but this time the VOCs coming off these things were unbearable! Going to try ordering directly from BlueAir, which is what I usually do with no problems. Fingers crossed that nothing has changed with how they make this product.
