Description
The Myco Labs 23" × 23" H14 HEPA Replacement Filter is the direct-fit filter for the Myco Labs Fan Filter Unit. Swap it in and your FFU is back to full cleanroom-grade airflow for agar, liquid culture and inoculation work.
It's rated 99.995% efficient at 0.3 microns for ISO Class 5 / Class 100 clean air, and it latches onto the existing fan housing, so there's nothing to rebuild.

Why replace with the matching filter
99.995% at 0.3 microns, the same grade your FFU shipped with, so your clean-air rating stays at ISO Class 5.
Built to the FFU's frame. The six safety latches hold it tight to the fan housing so air goes through the media, not around it.
The washable magnetic pre-filter on the back catches dust first. Rinse it regularly and the HEPA lasts years.
How to swap the filter
No tools needed. Work somewhere you can lay the unit down flat.
Turn the FFU off, unplug it and lay it down with the filter face up.
Open the six latches that join the fan housing to the filter box and lift the old filter off.
Set the new filter in place with the honeycomb face pointing out. Handle it by the frame, never the media.
Close all six latches, plug it in and run it for a few minutes before you start working.
Never wash the HEPA filter. Water and vacuums damage the media and the seal. Rinse only the magnetic pre-filter on the back of the FFU.
When it's time for a new filter
Fits the Myco Labs 23" × 23" FFU
That’s for typical hobby use; a busy lab should plan on 12–18 months. A dusty room, a skipped pre-filter rinse or heavy daily use shortens it. Keeping a spare on hand means a worn filter never stalls a batch of plates or transfers.
- Airflow drops on the same speed setting
- Media is torn, wet or damaged
- Contamination creeping up on clean work
This filter fits the Myco Labs unit only. Bonsai FFUs take their own filters.

HEPA filter replacement chart
There's no single expiry date for a HEPA filter. It wears out two ways: dust loading, which tracks run hours and how clean your room is, and aging of the media and gasket seals, which tracks the calendar. Plan on about 24 months for typical hobby use and 12–18 months in a busy lab. Keep it in service as long as it passes an agar plate test and holds its airflow, and replace it sooner if it doesn't.
Our HEPA filter replacement guide explains each row of the chart and walks through four simple tests (agar plates, a flame test, an anemometer reading and a pre-filter check) that tell you when your filter is actually done.
FAQ
What units does this filter fit?
It fits the Myco Labs 23" × 23" Fan Filter Unit only. Bonsai FFUs use their own filters, so order the Bonsai replacement filter for your Bonsai unit's size.
How long does the HEPA filter last?
For typical hobby use, plan on replacing it about every 24 months; in a busy lab running most of the day, every 12–18 months; and in a dusty, round-the-clock space, every 6–12 months. Some manufacturers recommend replacing as often as every 12 months, because filter media and seals age even when the unit isn't running. Treat 24 months as a planning number, and let an agar plate test and an airflow check tell you when it's actually done. Our HEPA filter replacement guide has the full chart and four simple tests.
How do I know it's time to replace it?
When airflow at the filter face drops noticeably on the same speed setting, or the filter media is torn, wet or visibly damaged, it's time for a new one.
Can I wash or vacuum the HEPA filter?
No. Washing or vacuuming damages the media and the seal. Only the magnetic pre-filter on the back of the FFU is washable.
How do I install it?
Unplug the FFU, release the six latches that join the fan housing to the filter box, swap in the new filter with the honeycomb face pointing out, then re-latch and run the unit for a few minutes before working.
What filtration rating is it?
H14 HEPA, 99.995% efficient at 0.3 microns, for ISO Class 5 / Class 100 clean air.
