Nearly all cars now come fitted as standard with a paper type air filter, why ? Well mostly owing to the costs of a paper filter, it’s very inexpensive to produce & let’s not forget, cars are produced in their millions – so every penny saved boosts profits. The most obvious disadvantage with paper, is that the filter media is just that, paper. As we all know, paper does not like to be exposed to water / humidity. The instant that the paper media becomes damp it’s efficiency as an air filter reduces drastically. Yet RamAirs’ Aeriform material is unaffected by moisture – namely owing to it’s unique polymer oil. All RamAir filters carry a limited lifetime warranty , which means that they are guaranteed against manufacturing defects for as long as the original purchaser owns the vehicle.
All RamAir filters are manufactured using Aeriform technology which means that every single air filter has variable stage air filtration. Each filter is constructed in two or three different grades of foam to ensure maximum air filtration, unlike cotton/gauze filters. Cotton air filters have only one grade of filter media, which means that once this becomes contaminated with particulates the air flow quickly deteriorates. Laboratory tests have proven that RamAirs’ Aeriform filter media will outlast all cotton gauze filters.
