Air Cleaning - Sure its allergy season, but there's more to it!

Monday, April 2, 2012 by Tom Ruse

Ok, the straight scoop. Whole-home high efficiency air cleaners - the kind installed in your heating and cooling system - have the ability to trap airborn allergens like no portable air purifier can. Its just a fact. A portable air purifier can only work in one room and only in a small area of that room!

Sure, if the allergens and other crap in your home are not airborne, the installed air cleaner can't trap it. You have to vacuum and dust.

But here's the key. The whole-home air cleaner only works when your HVAC system blower operates. When the blower operates it delivers conditioned air throughout your home and the air that's already there has to go somewhere. That's where your return air ducts come in. The old air,  and the crap in it, are returned to the HVAC system thru the return ducts and the air cleaner traps the crap before it goes thru the system again to be heated or cooled.

BUT, you can clean the air more often than when you are heating or cooling. Just run your blower fan more often (put it in the "on" position) and it'll recirculate that air even when you're not heating or cooling - so your CLEANING the air more often.

Installed, whole house air cleaners also help protect your expensive HVAC system and can reduce the amount of dusting and vaccuming you have to do. So, while some portables may take a few contaminants out of a small room, they don't do ANYTHING to protect you HVAC system. Nor will you see an appreciably difference in having to clean the place!
