Description

The Bonsai HEPAFLOW-12 Clear Coat + Extra Filter Bundle pairs the same 12"×12" horizontal laminar flow hood used across the Bonsai personal lineup with a second H14 HEPA filter included in the box — a ready spare for when your installed filter reaches the end of its service life. Both filters are rated 99.995% efficient at 0.3 microns.

Use it for working with agar plates, creating spore syringes, inoculating jars, bags, and substrates, grain-to-grain transfers, and cloning or isolating mycelium.

What's included

1× Bonsai HEPAFLOW-12 Clear Coat flow hood with 12"×12"×3" H14 HEPA filter installed
1× extra 12"×12"×3" Minipleat H14 HEPA filter (spare, uninstalled)
10' grounded power cord
Full user guide covering sterile technique, agar work, and syringe creation

How it's used

Assemble. Use the tool-free Click n' Twist system — about 15 minutes.
Power on. Let the HEPA-filtered air run for a few minutes to establish a steady laminar flow before starting work.
Set up your work. Position your agar plates, jars, or syringes inside the sterile air curtain at the front of the work surface.
Work in the airflow. Perform transfers, pours, or inoculations within the airflow zone, keeping hands and tools inside the curtain.
Swap in the spare when it's time. Store the spare filter sealed in its packaging until the installed filter fails an agar plate test, airflow drops, or it reaches about 24 months of typical hobby use.

Keep the spare sealed: leave the extra filter in its packaging until you need it, so it goes into the hood clean.

Don't need the spare?The standard HEPAFLOW-12C is the same hood without the extra filter, and the HEPAFLOW-12 replacement filter is sold on its own.

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.

HEPA filter replacement chart for FFUs and flow hoods: planning hours and calendar months by environment, from dusty 24/7 industrial use at 6–12 months to very light hobby use at 36–48 months

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

What's the difference between this and the standard HEPAFLOW-12C?

Same 12"×12" hood — this bundle also includes a second HEPA filter as a ready spare for when your installed filter reaches the end of its service life.

How do I know when to swap in the spare filter?

Plan on swapping it in around 24 months for typical hobby use, or 12–18 months in a busy lab. Swap sooner if the installed filter fails an agar plate test or airflow drops noticeably.

Is assembly difficult?

No — it's a tool-free Click n' Twist assembly that takes about 15 minutes.

I need a bigger work surface — what are my options?

For a larger sterile zone, step up to the Bonsai XL 24″×18″, or for commercial and multi-person use the Bonsai Commercial 48″×24″.

What's the warranty and return policy?

This unit carries a 3-year motor warranty. Unopened units are eligible for return; opened units are eligible for exchange only, and shipping damage is handled promptly. Ships via FedEx directly from the U.S.-based manufacturer.

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.
