The Defender air filter captures smoke, dust, dust mites, pollen, allergens and mold spores associated with insects such as cockroaches and pets. The HEPA filter is made with a wet laid, pleated, single layer of non-woven fibreglass and is wrapped around a cylinder that covers a surface area of 43.9 square feet. The activated charcoal filter fastens to unit with Velcro strips and provides an indicator light when the filter requires changing, which is on a monthly basis if operating full-time. No ozone is produced from this air filter unit, unlike many others on the market. The programmable three-speed motor works quietly and efficiently. Secure Seal and Pure Top Release technology prevents particulates from escaping the unit while it is running or during normal maintenance of the unit.

In the USA, this unit is classified as an FDA Class II Medical Device and has demonstrated excellent test results for the filter cartridge. The cartridge has proven an efficiency rating of 99.999 percent for removing particulates from the air.
