Bonsai Flow Hood H14 99.995% HEPA Replacement Filter for 2'x4' Commercial Flow Hood

The Bonsai HEPAFLOW-C 2’ × 4’ HEPA replacement filter keeps your Bonsai Commercial Series flow hood delivering clean, filtered air. It’s a 24" × 48" × 6" deep true H14 HEPA filter in an aluminum frame, rated 99.995% efficient at 0.3 microns.

Under typical conditions it’s rated for 3,000 hours of use, or about 3–5 years. Dusty, high-particulate workspaces can shorten that, so replace it before airflow or sterility drop off.

How to replace it

1. Power down. Turn off and unplug the flow hood.
2. Remove the old filter. Take out the used filter, handling it carefully to avoid releasing trapped particles.
3. Install the new filter. Seat the new filter evenly in the hood so it seals around the edges, with the airflow direction matching the hood.
4. Run before use. Turn the hood on and let it run before starting sterile work.
