Description
Description
The Bonsai Commercial Series 48" × 24" Horizontal Laminar Flow Hood is Bonsai's flagship 4'×2' unit — the most popular size for serious home or commercial mycology lab setups. Since 2019, Bonsai Filtration has built over 4,000 laminar flow hoods for professionals and hobbyists in the mycology industry.
The 48"×24" HEPA filter is built from water-resistant glass microfiber with hundreds of aluminum separators — the same class of filtration used in microbiology, microchip manufacturing, and nuclear laboratories. True horizontal laminar flow gives a steady, uniform sterile air curtain; many lower-cost all-in-one FFUs create turbulent airflow instead, which raises cross-contamination risk.
Freight shipping: the freight rate shown at checkout covers the lower 48 states. We can also ship to Alaska, Hawaii, and Canada — those routes are quoted individually, so please contact us for a rate before ordering. No shipping rate will appear at checkout for addresses outside the lower 48.

How It's Used
- Complete final assembly — about 5 minutes, since the unit ships 99% pre-assembled and pre-wired by a certified electrician.
- Power on and let the HEPA-filtered air run for a few minutes to establish a steady laminar flow before starting work.
- Position agar plates, grain, substrate, or spawn bags within the 48"×24" sterile zone.
- Perform transfers, pours, or inoculations — the wide surface supports multi-person operation.
- Power off after use. Replace the HEPA filter every 2–3 years under normal use.
Frequently Asked Questions
What's the difference between the Natural Clear Coat and Painted White finishes?
Both are the same 48"×24" commercial unit. The Painted White Finish costs $400 more than the Natural Clear Coat ($2,249 vs. $1,849).
How is this shipped?
It ships on a pallet via freight (FedEx Freight, UPS/TForce, or Estes). The flat freight rate shown at checkout covers the lower 48 states; Alaska, Hawaii, and Canada are quoted individually — contact us before ordering. Free local pickup is available by request, and a valid phone number is needed for delivery appointment scheduling.
How much assembly is required?
The unit arrives 99% pre-assembled and wired by a certified electrician — final assembly takes about 5 minutes.
How is true laminar flow different from a cheap FFU?
True horizontal laminar flow moves air in a steady, uniform stream across the work surface. Many inexpensive all-in-one fan filter units (FFUs) create turbulent airflow instead, which can increase the risk of cross-contamination.
I don't need the full 48"×24" — what are my options?
For a smaller footprint, see the Bonsai XL 24"×18" or the personal-sized HEPAFLOW-12C.
What's the warranty?
This unit carries a 3-year motor warranty.
