I ordered an Air Beast because it was the highest Merv rated filter that my HVAC system is compatible with. The delivery took about 10 days. The filter was easy to install. It looks exactly as described and appears to be of good quality. I bought it to improve the air quality in my home that was affected by the California wildfires. The merv 11 review doesn't capture the smoke but should help with the specific question. I've had it for about 5 days and it seems to be helping a little. I have it with an HVAC fan setup combined with a Hepa air purifier in the bedroom.
