Positive Pressure
Bio Hood
A full enclosed bio hood at a fraction of lab-grade prices. Top-down HEPA laminar flow creates a 24" × 24" positive-pressure workspace behind a generous viewing window. CNC aluminum. Cleanable with alcohol. Made in USA.
Top-Down Positive Pressure
The Model 1 FFU sits in a cradle on top of the cabinet and pushes HEPA-filtered air downward into the enclosed workspace. Positive pressure keeps unfiltered air out through the viewing window.
HEPA Filter Draws Air
The Model 1's ball bearing blower pulls room air through the H13 HEPA filter, capturing 99.97% of particles at 0.3 microns.
Clean Air Flows Down
Filtered air flows downward through the cabinet in a smooth laminar stream, bathing your entire 24" × 24" work area in clean air.
Positive Pressure Protects
Continuous airflow creates positive pressure inside the cabinet. Unfiltered room air can't enter — it's constantly being pushed out through the viewing window.
Lab-Grade Protection. Hobby-Friendly Price.
Comparable lab-grade bio safety cabinets cost $4,000+. The Model 2 delivers the same positive-pressure principle at a fraction of the cost.
24" × 24" × 24" Cabinet
Generous enclosed workspace with room for multiple jars, plates, and tools. Work comfortably without the cramped feel of a still air box.
Generous Viewing Window
Large front opening gives you clear sightlines and easy hand access while maintaining positive pressure inside the cabinet.
All-Metal, All-Cleanable
CNC plasma-cut aluminum construction. Wipe down every surface with isopropyl alcohol, acetone, or bleach. No porous wood to harbor contaminants.
Integrated Power
The Model 1 plugs directly into the Model 2 base. One cord to the wall — the bio hood handles the rest. 110V, standard US outlet.
15% Agar Discount Forever
Your purchase activates a permanent 15% discount code on your account for all Mycology-Supply agar products. Use it as often as you want.
Modular Design
The Model 1 lifts off the cradle for independent use or filter replacement. Two products, one system — maximum flexibility.
