The Lennox 92X08 HEPA 40/60 Foam PreFilter is a replacement foam pre-filter for the HEPA 40 and HEPA 60 Lennox Healthy Climate Indoor Air Quality HEPA systems. Contaminated air passes through this carbon pre-filter, allowing it trap large dirt and dust particles and then pass through to the HEPA filter, which will capture any remaining paticles. Lennox recommends replacing this Lennox Healthy Climate pre-filter every 12 months to increase the life of the HEPA filter.
