Healthy Climate®

High Efficiency Particulate Air (HEPA) Filtration System

Best possible air filtration performance

The Healthy Climate® HEPA-20 system uses hospital grade filtration technology to control contaminants. A sealed design helps contain particles in the system and keep them from bypassing the filter and going back into the home environment.

Reliable Performance

  • Sealed bypass design—traps particles and prevents them from escaping
  • Optional carbon filtration—helps remove odors
  • Powerful, yet quiet performance—completely and quietly filters the air inside the home, several times a day
  • Easy integration—designed to work with Lennox heating and cooling systems for total home comfort


  • True HEPA system—means the entire system has been tested to meet industry standards for particle/bioaerosol filtration
  • Near perfect filtration—up to 99.97% efficient in removing particles and bioaerosols down to 0.3 micron*
  • No ozone emissions—a known lung irritant**
