The new Lightning lifetime air filter from Ever-Flow features Mechano-Static technology, which combines the improved initial filtering efficiency of electrostatic air filters with the extended performance and dust holding of non-electrostatic (mechanical) air filters. This revolutionary filter is constructed using a total of 6 filtration layers, which combine to maximize overall filtering efficiency while minimizing resistance to airflow. The gasketed perimeter edge guarantees a proper seal to eliminate air bypass.

Furthermore, every Lightning lifetime air filter is treated with Micro-Shield BioStatic Surface Protectant, a patented micro-biostatic coating that kills microbes and bacteria on contact by physically penetrating their cell membranes with "Nano-Spikes". The coating is completely invisible, completely safe to humans and pets (EPA and FDA certified), and is renewed every time the filter is washed.

Every Lightning air filter includes a complimentary bottle of Ever-Flow Filter-Boost non-toxic water-soluble spray-on filter efficiency booster, as well as a bottle of Ever-Flow Enviro-Friendly Filter Cleaner.

Ever-Flow Lightning¨ filters are protected by a Lifetime Warranty and are 100% Made in the USA
