Description
The Lennox X4137 is a disposable carbon pre-filter that has a length of 6.7 inches, width of 3.3 inches and has a height of 3.3 inches and is intended for use with Lennox HVAC systems. In this capacity, it works as preliminary barrier, trapping relatively, larger particulate matters such as dust, dirt, and petrol particles before they may get to the primary filter. This adds to the quality of the main filter and aids to enhance the quality of air indoors by eliminating these pollutants which can move round your house.
