24"x24"x12" Negative Air Machine HEPA Filter - Wood Frame

HEPA is the acronym of High Efficiency Particulate Air. The HEPA filters can provide a high filtration efficiency for the particulate contaminants, which are above 0.3μm. The efficiency of HEPA filter is 99.7%. With the high efficiency filtration performance, the HEPA filter is widely used in the Air Scrubbers & Negative Air Machines to act as the last and most potent line of defense against fine particulate such as asbestos fibers, lead paint dust, mold spores, silica dust and other contaiminents that are hazardous to our health.

Engineered for maximum efficiency, the 24” x 24” x 11.5” Wood Frame HEPA Filter serves as the final and most critical stage in advanced air filtration systems. Designed to capture ultra-fine particles down to 0.3 microns, this third-stage HEPA filter provides 99.97% filtration efficiency, ensuring the air leaving your unit is exceptionally clean and contaminant-free.

This high-capacity HEPA filter is built with a sturdy wood frame for durability and consistent performance in demanding environments such as mold remediation, asbestos abatement, construction, and healthcare settings. Its ultra-fine filtration media traps microscopic particles like mold spores, bacteria, and fine dust, offering superior protection for both workers and occupants.
