The Clean Air Filter® features a unique, patent-pending, three-stage design.
The first stage is a PAPER ELEMENT that not only filters dust, but also absorbs liquid spray droplets.
The second stage is ACTIVATED CARBON to absorb organic vapors that the first stage is unable to filter out.
The third stage is an exclusive FINAL FILTER that stops chemical-laden carbon fines from passing through.

When should filter be replaced?
• If contaminant is detected
• End of application season
