Description
Commercial Air Scrubber and negative air machine utilizes a 3 stage filtration system for advanced air purification: 1 The first stage pleated pre filter is MERV 9 that collects and traps pollen, hairs, mold, and larger dust particles. 2 The second stage is an activated carbon filter that pulls in and helps to eliminate smoke and odors. 3 The final stage is a MERV 16 HEPA filter with an efficiency rating of 99.97% against 0.3-micron particles and will catch bacteria, allergens, dusts, and fumes. To maintain optimal performance it is recommended that the pre filter be changed every 3 months and the activated carbon filter be replaced every 6 months. There is an indicator light on the control panel that will illuminate when the HEPA filter should be replaced.
