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.
Warranty
Lennox Healthy Climate® equipment carries a limited warranty on the covered components; terms vary by product and registration. Milani registers the system at installation.
