To qualify as HEPA, an air filter must remove (from the air that passes through) 99.97% of particles that have a size of 0.3 µm³.
These filters are designed to remove and capture airborne particles such as: bacteria, spores, pollen, viruses, radioactive and a variety of other undesirable contaminants.
HEPA filters are almost exclusively used in medical, laboratory and commercial applications where totally clean air environments are required for human health and safety.
We supply HEPA filters of any size with MDF, ALU profile, ALU sheet or galvanized sheet frames.
Most common standard sizes are always available strait from our stock.
