1 review for Air Box 4+ Stealth 3500 CFM 12″ Flanges Carbon Inline Filter

  1. Todd Britton (verified owner)

    We installed an Air Box 4+ Stealth Filter on an exhaust duct for a laser cutter/engraver. The existing duct configuration was leas than ideal due to it’s length and quantity of elbows. We wanted to maximize the airflow yet still wanted an effective filter to eliminate odors associated with laser cutting before being exhausted to the outside. We were impressed with the “folded” configuration of the Air Box charcoal filters which provide a much larger filter surface area and subsequent airflow than a typical stacked filter. The quality of construction is excellent, and we appreciate that Air Box filters are made in the USA. The only questionable feature is very minor. The filter is decorated with a large Air Box 4+ decal. I am generally not a fan of providing free advertising for our equipment manufacturers but can see the value in displaying the company info when the time comes to replace filters. I am also oddly proud to have an Air Box filter in our shop.
