Air Purifier Reviews: Mold Filtration Options

Air purifier reviews and air purifier ratings as they pertain to improving indoor air quality via mold filtration are primarily focused on HEPA (high efficiency particulate arresting - accumulating - absorption - air) filters or ultraviolet germicidal irradiation (UVGI) filters. A HEPA filter draws air in through the purifier's fan and traps a minimum of 99.97% of particles that are 0.3 microns in size. A UV purifier actually kills mold spores as they enter the filter and are exposed to the ultraviolet light.

The IQAire Health Pro Series of HEPA filters are an example of a mold-spore filtration device that has received high ratings. IQAire Health Pro purifiers are actually classified as "hyper HEPA" filters due to their efficiency and speed of filtering the air; they are capable of filtering at least 99.95% of all particles that measure less than 0.3 microns in size and they trap 100 times more particles in the filter than a standard HEPA system.

While HEPA purifiers tend to be somewhat noisy and bulky and require periodic potentially expensive filter replacements, the IQAire systems are quieter than most HEPA systems. HEPA filters are also generally considered environmentally safe to operate.

The Professional Series Ionic Breeze GP is an example of an air purifier utilizing an ultraviolet light to control the mold spore levels in the air. Ratings for the Ionic Breeze system are usually very high due its quiet operation, low energy requirements allowing for continuous usage, and lack of filters to replace.

The Ionic Breeze relies on its unique electronic propulsion system to generate the airflow necessary to draw the mold spores into the system. The levels of ozone, which are emitted into the air due to the negative ion feature of the Ionic Breeze, comply with U.S. safety requirements.
