The PureAir Air Purification system uses Photocatalytic Oxidation process for removing today's most common household pollutants.  It is far and away the "Best" system for attacking all three classes of contaminants - particles, bioaerosols, and odors/chemicals. The PureAir system removes 75% of particles down to 0.3 micron, 60% of bioaerosols down to 0.3 micron, and it removes odors and destroys 50% of chemicals wihin a 24-hour period. According to Lennox, the PureAir system "cleanes the air in your home better than any other system you can buy."
