The key to effective air filtration is cleansing  all of the air. It's common sense that air will take the path of least resistance, therefore  "IF IT DOESN'T FIT IT DOESN'T FILTER". That's why  we make our air filters custom, to your specifications. And  because many air filter tracks have imperfections, design flaws and metal to metal seals that allow severe bypass,  we install our patented form fit gasket to our filters.  No bypass means your filtering 100 % of the air. Patented Design

If It Doesn't  Fit - It Doesn't Filter You can have the most efficient air filter possible, but what good is it if the air and pollutants go around the filter.  We have the patent on gasketed filters, and it makes all the difference in the way our air filters perform.
