Description
The Lennox 30340 is a 28″ x 20″ long air filter media for HVAC systems. This non-pleated media serves principally as a barrier to such extraneous and unwanted pollutants as dust, pollen, and worse allergens. When filters are blocked, there is a stranglehold on air flow, which in essence negates the efficiency of the system and there is the risk of increased energy usage. This helps to save on material that would otherwise be used in a trial-and-error method and also guarantees a perfect fit.
