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.
