Description

The Bonsai XL 24" × 18" Horizontal Laminar Flow Hood – Version 2.0 is built for serious cultivators and lab professionals who need significantly more sterile workspace without stepping up to full commercial cabinetry. Its 24"×18" H14 HEPA filter delivers true horizontal laminar airflow across a work surface more than 200% larger than a standard 12"×12" personal hood.

Use it for grain-to-grain transfers, agar pours, spore syringes, inoculating jars, bags, and substrate blocks — with enough room for two people to work side-by-side under sterile airflow.

How It's Used

  1. Assemble the hood using the tool-free Turn-N-Click system — about 15 minutes.
  2. Power on and let the HEPA-filtered air run for a few minutes to establish a steady laminar flow before starting work.
  3. Position agar plates, jars, spawn, or substrate within the wide sterile zone — there's room for a second person to work alongside you.
  4. Perform transfers, pours, or inoculations within the airflow zone, keeping hands and tools inside the curtain.
  5. Power off after use. Replace the HEPA filter every 3–5 years under normal use.

Frequently Asked Questions

How much bigger is this than the 12"×12" hoods?

The 24"×18" filter gives a work surface more than 200% larger than a standard 12"×12" personal hood like the HEPAFLOW-12C — useful for higher-volume work or working alongside a second person.

Can two people work at the hood at the same time?

Yes — the wider work surface is sized to let two people work side-by-side under the same sterile airflow.

How does this compare to the Commercial 48"×24" hood?

The XL is a benchtop upgrade at 24"×18" with free ground shipping. The Commercial 48"×24" is Bonsai's largest and most popular commercial size, built for serious home or commercial lab setups and shipped by freight.

Is assembly difficult?

No — it uses a tool-free Turn-N-Click assembly system and is ready to use in about 15 minutes.

What's the warranty and return policy?

This unit carries a 3-year motor warranty and ships free within the continental USA. Unopened units are eligible for return; opened units are eligible for exchange only, and shipping damage is handled promptly.
