What makes the Dri-Eaz DefendAir HEPA 500 unique is its Clean Air Delivery Rate (CADR) capability. For air filters that have air flowing through them, it is the fraction of particles (of a particular size distribution) that have been removed from the air, multiplied by the air flow rate (in CFM) through the device. Almost counter intuitively, the slower the velocity of the air passing through the filter, the more efficient the HEPA filter becomes at removing even the smallest particles in the air. The M67 system, optimized for ambient capture only, is the best value in this class with up to 1900 cfm. The large difference is due to the numerous design conservatisms inherent in air movement. What sets HEPA filters apart from the rest is their claims are more than just claims. Comes in white color family.
