7158 Green Filter Air filter - Ford Fiesta, Fiesta ST, B-Max, Mazda 2

Unlike multi-layer gauze filters which can fray and release fiber particles into your engine, Green Filter USA uses two layers of tightly-interwoven cotton fabric. The 3 main benefits to woven cotton are the fact its thinner, holds oil better, and is stronger. Since its thinner, it allows better air flow without sacrificing filtration. The cotton holds the oil more evenly, and the medium is much stronger. Unlike gauze, you cannot wear a hole in woven cotton by rubbing it, and there is no way small bits of cotton can rip off since its interlocked with another piece.

Cross weaving one fine, and one medium layer, produces a fabric that is thinner and stronger than other materials and has the ability to trap dirt up down to 5 microns. The result is better airflow without sacrificing filtration. And because the fabric is so durable, they can be washed and reused over and over, which allows us to give it a lifetime guarantee.

Green Filter USA filters come pre-treated with a specially formulated dirt trapping oil. This oil creates a positive magnetic charge, or ionic bond, with the filters stainless steel mesh. The positive charge attracts the negatively charged dust particles entering the filter, causing them to cling to the steel mesh and allowing the cotton to remain clear for maximum airflow.

Economical - A paper filter should be replaced between 4,000 to 5,000 miles or every oil change. The average cost of a paper filter is about $10 to $12. After one year of driving 15,000 miles, at least 3 paper filters are needed. This totals $30 to $35. After one to two years, a Lifetime Green Filter is already paid for. This benefit is for everyone - a daily driver, an older vehicle or someone looking for the best performance.
