Are HVAC Systems the Answer?

When business owners hear that indoor air is two to five times more polluted than outdoor air—which is already heavily polluted—they think the solution lies in focusing on the building’s HVAC system. But that may not solve the problem of poor air quality.
Here’s why:

HVAC systems work because they recirculate air. But they don’t do a thing about cleaning the air. Filters can trap very large particles, but things like volatile organic compounds (VOCs), germs, bacteria and allergens pass right through typical HVAC filters. That doesn’t alleviate the problem of poor air quality inside buildings.

Business owners and facility managers may think installing HEPA filters in existing HVAC systems will do the trick. It won’t. That’s because HEPA filters designed specifically for HVAC systems are bulky, and while they do a better job of trapping germs in the direct area near the intake, these thick filters drag down HVAC efficiency, significantly reducing airflow. So, HVAC will work harder, break down more often and still not solve the poor air quality problem. Additionally, these modifications to existing HVAC systems do nothing for areas that aren’t near the intakes.

Perhaps most importantly, HVAC systems spread germs farther and faster through recirculation. In essence, HVAC systems are air movers, not air improvers. There just isn’t enough efficiency in HVAC systems, because they are designed first and foremost to push air throughout buildings. Also, HVAC systems focus on the entirety of buildings, pushing air at the same rate throughout. That means indoor air quality problem areas will be ignored.

Instead of recirculating poor air, building managers and business owners need to focus on removing it. In our opinion, the best way to do that is by installing AeraMax Professional air purifiers. These commercial-grade systems use hospital-type True HEPA filtration to effectively, quickly and efficiently remove 99.97 percent of airborne contaminants, like germs, bacteria, smoke, odors, allergens and VOCs, from indoor air. The four-stage filtration systems work automatically, because the units sense when poor air is present, adjusting to remove the bad air.

And, AeraMax Professional offers an array of different units to accommodate a variety of room sizes—and even have portable units so specific areas can be targeted on the fly, by moving the purifier into offending areas.
