Clean Room Mushroom Laboratories HEPA Air Filter

Core Function of the HEPA Filter

HEPA = High Efficiency Particulate Air filter.
Its role in a cleanroom is to scrub the air so that particles—especially microscopic ones—don’t float around and settle on your production surfaces, mushroom spawn, or sensitive devices.

• Particle removal efficiency:
  A true HEPA removes 99.97% of all particles with a diameter of 0.3 microns (that’s about 1/300th the width of a human hair). If it can handle 0.3 µm particles, it’s even more effective on both larger and smaller sizes due to how fluid dynamics work (fun paradox!).

• Target contaminants:

  • Dust particles (carriers of all sorts of mischief).
  • Mold spores, bacteria, pollen—exactly the arch‑nemeses of mushroom cultivation.
  • Fine aerosols that your eyes can’t even detect.

How It Works (Without Too Much Sci‑Fi Magic)

Air passes through a dense mat of randomly arranged fibers (usually glass microfiber). Three different mechanisms trap particles:

1. Interception: Particle brushes against a fiber and sticks.
2. Impaction: Larger particles can’t dodge around the fibers and slam right into them.
3. Diffusion: Tiny particles zigzag around (thanks to Brownian motion) and eventually get snagged.

0.3 microns is the “most penetrating” size: too big for zigzagging diffusion, too small for easy impaction—so if the filter catches those, it catches everything else even better.
