Description
Description
The Myco Labs 2' × 4' HEPA Fan Filter Unit (FFU) is twice as wide as our 23" unit: a 47" stream of H14 HEPA laminar airflow, so you can work a full row of plates, jars or bags at once. Lay it on a bench as a wide flow hood, or drop it into a standard 2' × 4' ceiling grid for a clean room.
Air passes through a pre-filter on the intake first, then an H14 HEPA filter rated 99.995% at 0.3 microns for ISO Class 5 / Class 100 clean air. Inside the aluminum-zinc plated steel housing is an aluminum fan wheel on a copper-wound motor, with a three-speed knob and a standard 110V plug.

What's inside the Myco Labs 2' × 4' FFU
A pre-filter over the fan intake catches dust and larger particles first, so the H14 HEPA filter only has to handle the fine particles on the final pass.
One knob: Off, Low, Middle, High, for 0.45–0.6 m/s at the filter face. Power comes in through a fused inlet on the control box.
Safety latches lock the fan housing to the filter box, and insulated handles on both ends make the unit easy to carry and position.
How to set it up as a flow hood
On a bench the FFU works like a horizontal laminar flow hood: clean air blows from the filter face across your work area and toward you.
Set it on a sturdy table at least 4' wide, HEPA face toward you, with a few inches of open space behind the intake.
Connect the cord to a standard 110V outlet and turn the knob to the speed you want.
Run it for a few minutes and wipe the work surface with alcohol before you open anything.
Keep plates, jars and bags between the filter and your hands, and never reach over an open plate.
Raise your work into the airflow: the cleanest air comes straight out of the filter face. A stainless steel workspace riser lifts plates and jars up into it.
Built to the 2' × 4' clean-room standard
47.1" × 22.9" × 11.75"
At 47.1" × 22.9", the Myco Labs FFU drops into a standard 24" × 48" ceiling tile grid, the way FFUs are installed in commercial clean rooms. On a bench, its 11.75" depth leaves more of your table free than a cabinet-style hood.
- Wide benchtop flow hood for agar, LC and bag work
- Ceiling grid FFU for a modular clean room
- Clean air over a production or packing table
A flow hood is a fan, filter and cabinet built for one bench. An FFU is the fan and filter in one box, so it can go on a bench or into a ceiling.
Our flow hood vs FFU guide compares both.

HEPA filter careNever wash or vacuum the HEPA filter face. Keep the intake pre-filter clean so dust doesn't load up the HEPA, and the filter will hold its airflow longer.

When to replace the HEPA filter
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
Can I use it as a flow hood on a table?
Yes. Stand it on its long side on a table at least 4 feet wide with the HEPA face toward you, and it works like a wide horizontal laminar flow hood for agar, liquid culture and inoculations.
Will it fit in a drop ceiling?
Yes. The unit measures 47.1 by 22.9 inches and fits standard 24 by 48 inch ceiling tile grids, like the FFUs in commercial clean rooms.
What HEPA filter does it use?
An H14 HEPA filter rated 99.995% efficient at 0.3 microns, for ISO Class 5 / Class 100 clean air. A pre-filter on the intake catches larger particles first.
Does it need special wiring?
No. It plugs into a standard 110V household outlet.
Can I wash the HEPA filter?
No. HEPA filters should never be washed or vacuumed. Keep the intake pre-filter clean so dust doesn't reach the HEPA and it lasts longer.
How is it different from the Myco Labs 23 x 23 inch FFU?
Both use H14 HEPA filters and three-speed controls. The 2 x 4 is twice as wide, moves up to 1,440 cubic meters of air per hour versus 800, and fits a 2 x 4 ceiling grid instead of a 2 x 2.
How is it different from the Bonsai 4' x 2' FFU?
Both are H14 HEPA, ISO Class 5 units with a 4-foot filter face. The Myco Labs unit is slimmer at 11.75 inches deep and sized for a 2 x 4 ceiling grid. The Bonsai is 14 inches deep, reaches up to 160 FPM, has a washable magnetic pre-filter and carries an 18-month warranty.
How often should I replace the HEPA filter?
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.
