"Our tests prove the efficiency, loading capacity, durability and ease of cleaning of Fiberlene filters to be more than adequate. We use magnehelic gauges and other tests to measure air flow and pressure drops as air filters are loaded. Fiberlene filters demonstrate a short "pay back" through utility savings and extension of A/C unit life. Purchasing and disposal of temporary filters is eliminated. Most importantly, we get cleaner air for our customers and employees."
