MiracleAir HEPA air cleaner for the home

Enhance indoor air quality with the PM400 MiracleAir® and provide TRUE hospital grade HEPA filtration. The PM400 maximizes the amount air flowing through the large HEPA filter while maintaining an optimal air-to-cloth ratio for best filter life.

Durable and rugged, the PM400 air purifier is ideal for commercial and institutional environments and is even suitable for some industrial uses. The PM400 is so versatile it is often used in residential settings on lower speed settings when real commercial grade true HEPA filtration is desired. Multiple units can be used for larger areas.

Among other measures for enhanced air filtration, the CDC suggests use of portable HEPA air cleaners in the COVID-19 engineering controls for ventilation section of the pertinent guidelines for office buildings. An ASHRAE position document is also linked by the CDC, suggesting the same exposure control use of portable HEPA air cleaners as well. In addition, the scientific literature states “Portable HEPA filter systems have been shown to be another effective tool in reducing viral load.” Air Quality Engineering produces the hospital grade HEPA portable air purification units such as referenced in the scientific literature. Our PM400 uses proven hospital grade HEPA filtration to remove potentially harmful microscopic particles. Therefore, there are no ozone emission concerns such as those found in some ionizing units. Let our true HEPA filtration units reduce contaminant concentrations and:

  • Improve the air quality in your office space
  • Improve the air quality in retail and commercial environments
  • Improve waiting area or lobby air quality
