Designed for Restoration
The HEPA 500 is ideal for handling indoor air quality needs on every restoration job. Restoration that involves sewage, mold, or fire damage involves significant amounts of particulates and bad-smelling gasses – a direct result of the damage itself. In a water damage restoration environment, the high-velocity airflow needed for drying can stir up particulates that have settled in carpet or on other materials. The HEPA 500 addresses these air-quality issues quickly and effectively, helping you to maintain a clean, odor-free indoor environment for your technicians – and your customers.
1st Stage Pre-Filter (F270). Synthetic fiber filter media rated at 10% efficiency. Captures the largest particles to help extend the life of the higher efficiency filters inside. More info.
2nd Stage Pre-Filter (F271). Synthetic fiber filter media rated at 30% efficiency. Captures larger particles to help extend the life of the HEPA filter.More info.
DOP Stage 2 Pre-Filter (F415). Use of the DOP filter ensures laboratory-rated performance for sensitive jobs requiring first-pass HEPA filtration. More info.
Activated Carbon Filter (F397). The activated carbon filter allows the removal of a wide variety of compounds, including volatile organic compounds (VOCs), food odors, fumes from paint and paint thinners, sewer odors, and many other noxious odors. Combining activated carbon filtration with HEPA filtration is especially effective in removing airborne soot particles and the odors they create. More info.
