Replacing Your Lennox Furnace Filters

Replacing Your Lennox Furnace Filters

Replacing your Lennox Furnace Filters is important for the air quality inside your home as well as for the efficiency and longevity of your Lennox furnace. Lennox is one of the most reliable and well recognized brands in home heating and cooling systems. They recommend replacing the filters 4 times a year – at the start of each season. The quality of your indoor air can the 5 times as bad as the quality of the air outside as pollutants enter your home through the heating and cooling system. Once they are in the home, they will stay there unless they are removed. Furnace filters remove the particle and irritants in your air, leaving it clean and healthy to breathe.

Airborne particles as little as 0.3 microns are no match for Lennox Furnace Filters. This means that Lennox filters are able to trap pet dander, mold, viruses, bacteria, dust, fungi, and allergens of all varieties. Clean furnace filters can keep the air inside your home healthy and fresh. Lennox filters are specially designed to trap these pathogens and to prevent any leaks around the filter. Some Lennox filters are as thick as six inches, capturing more air particles than typical one and two inch thick filters.

Poor indoor air quality increases the risk of health issues for your family. Replacing your furnace filters is important for your health. Every season produces its own unique health issues, like seasonal allergies and the flu. Clean furnace filters can help. Changing your Lennox filters each season enhances their ability to trap these seasonal pathogens and keep your home healthy.

Lennox filters use their own unique design, known as a hammock filter. Hammock filters are placed between the duct work and the furnace. As the air passes through the filter, microbes and particles are removed from the air. Changing these filters is easy, and does not require the help of a repair service.

The first step to replacing your Lennox filter is to turn off power to the furnace. Next, remove the access panel on the outside of the air handler. Use a screwdriver to remove the screws, and then remove the access panel. Inside, locate the filter frame and slide it out. Use the tabs on the side of the frame to release the filter from the frame. Remove the dirty filter and set aside to be discarded. Slide the new filter into the frame with the colored side up, and then close the tabs. Slide the frame back into place and reattach the access panel.
