Today, there is a growing awareness of the importance for improving indoor air quality and energy efficiency. Of course, this is a significant and welcome development.
But how do the claims being made for air filtration and ventilation systems really relate to performance?
Since 1987, homeowners and businesses have relied on the Minimum Efficiency Reporting Value (MERV Rating) to know the effectiveness of air filtration systems. The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), a widely respected international body responsible for building codes across the world, created the MERV Rating. ASHRAE’s MERV rating is 1-16, where the higher number is a greater percentage of hazardous particles captured.
Air filtration ratings are important, and cleaning systems undergo industry-standardized tests to earn their MERV ratings. Systems are tested when particles that fall into one of twelve categories, based on the size of the test particle captured. The air is passed through the filtration system, and the effectiveness of the filtration media analyzed to see how well it removes pollutants in each size category. The smallest category of particles range from .3 to .4 micrometers and the larger particles range in size from 7 to 10 micrometers.
ASHRAE requires a minimum MERV Rating of 6 for residences. General commercial buildings and industrial workspaces typically use systems that score 5-8.
The RecoupAerator® filter media rated a MERV 12. According to the Environmental Protection Agency, this score usually applies to “Superior Residential” units and “Hospital Laboratories” and means that UltimateAir®’s RecoupAerator® 200DX removes dangerous contaminants from the air, including trapping virtually all pollen and mold spores.
Alongside air quality, energy efficiency is also of critical importance to homeowners. This is particularly true today due to rising energy prices and the current state of the economy. In general, the better the air filtration in an air moving appliance, to more energy it takes.
However, according to an independent study commissioned by the Maryland Aviation Administration, the RecoupAerator® 200DX is significantly more energy efficient than other systems on the market. The average annual net cost of operating the RecoupAerator® 200DX is only $59 dollars. The average cost of competing products is more than twice this amount.
And the RecoupAerator® accomplishes this filtration while exhausting stale and polluted indoor air and providing for the continuous introduction of fresh outside air.
“Green” is the latest buzzword and businesses are clamoring to brand their products the cleanest and the most efficient. By doing a bit or research, homeowners can educate themselves and make smart purchases that will substantially improve the health of their families with minimal damage to their wallets and pocketbooks.
