About Lennox Filters

Lennox Furnace Filters

In today’s well-built, energy efficient homes, indoor air quality is often sacrificed for more efficient insulation. The better a home is insulated, the more dirt and other unsavoury particles can become trapped in the air you breathe. Studies show that indoor air quality can be up to five times more polluted than the air you breathe when you are outdoors.

Take control of your home’s indoor air quality by using Lennox furnace filters and replacing them regularly. You’ll soon experience cleaner air, and there will be less dirt and dust accumulating on your floors, carpets and furniture. Replacement furnace filters will work to reduce the number of airborne allergens and other irritants in the air, reducing the number of colds and flu your family experiences. Respiratory ailments like asthma will also likely improve, since there will be less debris in the air to irritate these conditions.
