Measuring Efficiency of Air Purifiers

Are the season’s extremely high pollen levels causing you severe discomfort?

While you can’t control the environment outside, there are some things you can do to find relief from your symptoms indoors. A few weeks ago we did a story on our indoor air quality services, including the implementation of a whole home air purifier.

Simply installed by your air conditioning company, these systems are ideal for removing airborne allergens and other irritants from the air, to provide your family with only clean air. If you aren’t familiar with the equipment, it can be overwhelming when shopping around for a system. Fortunately, testing standards and rating systems have been developed to help evaluate the efficiency for easy comparison shopping.

Evaluating the Efficiency of Air Purifiers & Their Filters

There are two common methods of evaluating the efficiency of air purifiers and their filters. One such method, the Minimum Efficiency Rating Value (MERV), measures the efficiency with which a purifier’s filter removes air particles on a scale of 1-16. The greater the MERV the more efficient the filter is. Other systems, including Trane air cleaners, use the Clean Air Delivery Rate (CADR) which was developed by the Association of Home Appliance Manufacturers (AHAM) to not only determine a purifier’s efficiency in capturing airborne particles, but also the rate at which is delivers clean air back into the room2.

The system is given three ratings, one for the purifier’s removal of pollen, dust, and tobacco smoke which are combined for a grand total with a maximum CADR of 1,3002. Contacting indoor air quality specialist is a good idea for evaluating your options.

Quality Indoor Air Purifying Services

The Trane CleanEffectsTM air purification system delivers a CADR of 1,200 which is significantly greater than that of the typical portable device (CADR 10)3. If you suffer from asthma or severe allergies, this system is ideal for removing air particles ranging from pollen and dust to viruses and bacteria which can irritate systems.
