The new Lightning® lifetime air filter from Ever-Flow® features proprietary 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 5 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
