Product Details
The Air Box Stealth Edition Carbon Filter is a professional-grade, inline air filtration system built for grow rooms, commercial spaces, industrial facilities and homes. It runs quietly while scrubbing odors, removing contaminants and pathogens, and helping move excess heat out of your space, so you get a steady supply of clean, fresh air. Made in the USA, the Stealth Edition comes in five sizes covering 4" to 12" flanges and up to 3,500 CFM.
Why Choose the Air Box Stealth Edition?
- 100% premium virgin coconut-shell carbon: High-activity, steam-activated charcoal with a well-developed pore structure that adsorbs a broad range of organic and inorganic odors and contaminants.
- Replaceable high-flow cartridges: When the carbon is spent, swap the cartridges instead of the whole unit. The housing stays in place, so a refresh is quick and less costly.
- Leak-free, air-tight design: Every cartridge seals with a neoprene gasket inside a factory-assembled housing. All air is forced through the carbon, not around it, so 100% of the filter surface area does its job.
- Rugged metal enclosure: A sturdy, low-profile metal housing that hangs easily inside or outside your grow room or building.
- Adaptable to any duct system: Standard 4", 6", 8", 10" and 12" flanges connect directly to your existing ducting and inline fan.
- Pre-filter on larger models: The Air Box 3, 4 and 4+ include a pre-filter that catches dust and debris before it reaches the carbon, extending cartridge life.
- Easy to install, use and maintain: Simple hang-and-connect installation and quick cartridge changes keep downtime to a minimum.
- Made in the USA.
