Air Box Stealth Series air filtering systems 

Hydrotek redesigned the Airtech Carbon Series to create a new generation of filtering systems named Air Box Stealth Series. 

The Air Box Stealths use 100 per cent premium virgin coconut charcoal for better filtration of bad air and fertilizer odors. The activated carbon granules are an absorbent with well-developed pore structure allowing for a range of absorbent retention.

Rather than using a standard filter, the Air Boxes use cartridges that are lightweight and very inexpensive compared to standard filters. Your initial investment is a little higher, but the money saved over the long haul buying replacement cartridges makes the Air Box an economical filtering system.

100% of the filter surface area is used! The Air Box Stealths are air tight for continuous worry-free operation.

Easy to install and maintain, they use replaceable high-flow cartridges that are designed to be easily replaced, without dismantling your ventilation setup.

The Airbox is an "in-line" filter (openings on both ends to connect your ducting to) unlike most other filters which are "pre-exhaust" (only one place to connect your ducting). Airbox units are made specifically to fit up between the joists in your basement, in order to save space and add headroom.

These fan filters have high CFM ratings:

Air Box Stealth Edition 2 - 1000 CFM - Connects to 6" ducting - Holds two cartridges
Air Box Stealth Edition 3 - 1500 CFM - Connects to 8" ducting - Holds three cartridges

They are adaptable to any duct / filtering system. The Air Box Stealth is made in the United States with quality components.
