The Best Whole House Air Cleaner
We just had this air purifier installed today with a new furnace and AC. The filter on this IQAir filter is supposed to last 3 years and it produces absolutely no Ozone which was not the case for the other whole house air filters we evaluated. I’ll let you know if my allergies get better after installing this filter after the first month, second month, and so on. The filter is actually supposed to get better as time goes on. Don’t ask me how that works. 
My allergies are already getting better. I just hope the filter lasts as long as they claim ( 3 years). I’m a little skeptical it will really last that long and still keep the air super clean, but we’ll see.
