&checkmark; 3-stage filtration system for advanced air purification 
&checkmark; Indicator light illuminates when the HEPA filter needs to be replaced 
&checkmark; Stackable (up to 3 units) for space-saving storage 

The Global Industrial&#153; Commercial-Grade Air Scrubber and Negative Air Machine is your solution to delivering advanced levels of air purification for areas in construction, disaster relief, home remodeling, reclamation, reconstruction, and more. Constructed from rotomolded plastic evenly layered in a second skin that's thicker than injection molding, this machine permits higher levels of flexibility and endurance during extreme temperatures or rough impact. It features a 3-stage filtration system that consists of a MERV 9 pre-filter, an activated carbon filter, and a HEPA filter to trap common allergens and eliminate smoke and odors. Ideal for use in commercial or industrial environments, this unit is equipped with two GFCI-protected power outlets, allowing it to be daisy-chained for a maximum of three units on one circuit. When placed as a stand-alone unit, this versatile machine acts as an air scrubber. When attached to ducting, it works as a negative air machine, exhausting filtered air outside the affected area. Limited 1-Year Warranty. 

<li>First stage: pleated MERV 9 pre-filter collects and traps pollen, hairs, mold, and larger dust particles</li>
<li>Second stage: an activated carbon filter pulls in and helps to eliminate smoke & odors</li>
<li>Final stage: a HEPA filter, with a 99.97% efficiency rating against 0.3-micron particles, that catches bacteria, allergens, dust, & fumes</li>
<li>Replace the pre-filter every 3 months & the activated carbon filter every 6 months</li>
<li>Optional accessories such as flexible ducting (models 292943 & 292944) and a caster conversion kit (model 292942) are sold separately</li>
