Stop Losing Batches to Contamination.
Steriflo gives serious mushroom growers HEPA-filtered airflow across the bench, without the lab price or the lab size.
“I have used the flow hood twice (multiple items per use) and have not run into any issue so far! No contamination is showing and everything is looking healthy.”
Three Plates in the Airflow. Three in the Room. One Set Grew Mold.
Myco Alchemy Co.'s bench test: six identical agar plates, lids off, same room, same hour. Three sat in front of a running Steriflo. Three sat open on the bench beside it. After one hour we lidded all six and left them five days.
The bench plates grew mold. The plates in the filtered airflow came back clean.
That is the whole argument. Still air reduces movement — it doesn't remove particles. Every jar you open, every breath you take, every movement puts spores back into play. Steriflo pushes a steady stream of H13-filtered air across your work surface, so airborne particles are carried away from your plates instead of settling onto them.
This is Myco Alchemy Co.'s own bench demonstration, not a lab study. Your results depend on your technique and your room.

Turbulent Air vs HEPA-Filtered Directional Airflow
TURBULENT AIR
HEPA-FILTERED AIRFLOW
Still air boxes got you started. They’re holding you back now.
As your grows get more serious, inconsistency becomes the enemy. A still air box reduces air movement — it doesn't control it.
STILL AIR BOX VS FLOW HOOD — A SIMPLE COMPARISON

Built to a Spec Sheet, Not a Marketing Sheet
The facts we can show you. 110V US plug — no adapter, no voltage surprises.
True H13 HEPA Filtration
H13-rated HEPA filter behind a prefilter. Not “HEPA-style.” Not “HEPA-like.”
Three-Speed Airflow Control
Low / Med / High. Dial in the right flow for agar, grain transfers, or liquid culture.
Fold-Flat Handles
22.6″ × 22.6″. Fits a standard workbench. Handles fold flush when not in use.
Tool-Free Spring Latch
Holds the filter firmly against its foam seal, and opens without tools when it is time for a new filter.
Two-Stage Prefilter Protection with Steel Mesh Reinforcement
Two-stage filtration. The prefilter takes the heavy load first — dust, spores, large particles — so the H13 HEPA never has to. Steel mesh reinforcement holds the media firm under pressure.
PREFILTER FRONT (LIGHT)
PREFILTER BACK (DARKER)
STEEL MESH CLOSE-UP
Steel mesh woven through the filter media. Keeps the pleats from collapsing under airflow pressure. The prefilter stays effective longer — and so does everything behind it.
One Dial. Three Speeds. Total Airflow Control.
Three-speed dial. LOW for agar work and grain transfers, when you want steady, quieter airflow. MED for longer work sessions. HIGH to move the most air through the H13 filter.
One unit, three ways to work.
See It Run. Then See Every Unit Tested.
Real airflow, real bench. Every unit then passes a 32-point inspection — power-up, blower speed, and visual checks — before it ships.

Frequently Asked Questions About the Steriflo Flow Hood
A still-air box keeps air still so less settles on your work. A flow hood blows HEPA-filtered air across your work surface, so particles are carried away and you can work with an open front and both hands free.
Comparable 2×2 flow hoods we checked in September 2026 cost $699 to $899.95. Steriflo is $499 with free US shipping. A single failed batch costs roughly $100–140 in grain, substrate and culture, so about four failed batches cost as much as the hood.
Yes. The open front gives you room for plates, jars and syringes, and the three speeds let you choose steadier, quieter airflow for delicate agar work or more airflow for longer sessions.
Yes. 110V US standard — no voltage adapter needed. This matters because many budget flow hoods on Amazon ship from China with 220V specs and won't work on US outlets. Steriflo is built for the US market. Plug it in, turn it on, start working.
Yes. The spring latch opens without tools, so you can swap the filter yourself. Email hello@gro-myco.com when you need a replacement filter.
12-month warranty against manufacturing defects, from the day it arrives. 30-day returns on unused items in original packaging; the buyer pays return shipping. If it arrives damaged, email photos within 48 hours and we will make it right. Full policy.
It ships free from our warehouse in Elk Grove, California, within 1–3 business days, then typically arrives about 7 days later. We ship to US addresses only. You get a tracking number by email when it ships.
If you grow occasionally, a still-air box is a fine place to start. A flow hood makes sense once you are doing regular agar, grain or liquid culture work and losing batches or time to contamination.
