I'm a big fan of these Aprilair media air cleaners. They capture 97% of pollen sized airborne particles, have 30x the filtering capacity of a standard 1" furnace filter, and they only need changes once per year! Join Bert and I for a quick tour of a retrofit install with this product.
So upon installation i was wanting to know if you had to modify the fan and if so how much more of a percentage did you increase?
