Design & Manufacture
The filter media is made of 4 layers of high quality surgical cotton gauze sandwiched between two layers of epoxy coated marine grade aluminum wire mesh pleated by state of the art electronically controlled machines to assure a very high quality of filtration media. The result of the special design and the hi-tech manufacturing process is a filtration media that has very high flow rates, low restriction, superior dust holding capability and smoothens out the air flow stream.

Special Oil
Oil that is used to impregnate the cotton is a very special grade developed by the DNA R&D department after intense testing and produced by one of the world's best oil companies. This special oil is a very critical part of the filter and has the capability to produce a static charge to the cotton media and attract the entire dust particles that flow towards the filter, even the very fine ones.
