Healthy Climate® HEPA Filtration System
The Healthy Climate® HEPA Filtration System delivers true hospital-grade particulate filtration for the whole home. A HEPA filter is too restrictive to put directly in the main airflow, so this system uses a bypass: it draws a slice of the return air through the HEPA cabinet and feeds it back into the supply.
True HEPA, on a bypass
A sealed cabinet installs off the ductwork with its own small blower. Over a run cycle it continuously scrubs a portion of the home's air to HEPA standard — 99.97% of particles at 0.3 micron — while the furnace's own filter handles bulk filtration and protects the coil.

How Milani installs it
Whole-home Lennox air quality equipment installs in the ductwork near the furnace or air handler, so it treats the air every time the system's blower runs — no portable units to move between rooms. Milani sizes it to the system's airflow, sets it up with the thermostat where applicable, and shows you the filter or lamp maintenance schedule.
