The Bonsai 2 × 2 ft HEPA Fan Filter Unit (FFU) is a professional, cleanroom-grade fan filter unit for mushroom cultivation and sterile lab work — an affordable, space-saving alternative to a full laminar flow hood. It delivers true HEPA-filtered laminar airflow for agar work, grain jar and spawn bag inoculation, liquid culture, tissue culture, and any task that demands a clean-air workspace.
Unlike low-cost FFUs that cut corners with plastic blower assemblies and thin housings, every Bonsai FFU is engineered with premium upgraded components for better durability, quieter operation, longer service life, and more consistent airflow. With a shallow 14" depth and an integrated high-performance blower, it provides ISO Class 5 / Class 100 clean air without the bulk or cost of a traditional flow hood cabinet.
FFU or full laminar flow hood? For most home growers, this FFU works as a complete flow hood solution. If you want to compare both options before you buy, read our Laminar Flow Hood vs FFU guide — we built and tested both to show exactly where each one shines.
Premium Upgrades That Set Bonsai FFUs Apart
- Upgraded Aluminum Centrifugal Fan – A durable backward-curved aluminum blower wheel instead of the cheap plastic fans found in most competing FFUs.
- Heavy-Duty 20-Gauge Powder-Coated Aluminum Housing – A custom white powder-coated frame built for long-term durability and a professional cleanroom appearance.
- Magnetic Washable Electrostatic Pre-Filter – A reusable magnetic pre-filter that extends HEPA filter life and never needs replacement under normal use.
- True H14 HEPA Filtration – Certified 99.995% filtration efficiency at 0.3 microns for ISO Class 5 / Class 100 clean-air performance.
- Optimized Laminar Airflow – Designed specifically for sterile laboratory and mycology applications requiring clean, even airflow.
- Extended 18-Month Warranty – Backed by an industry-leading warranty for peace of mind and long-term reliability.

- Inoculate grain jars, spawn bags, and substrates with reduced contamination risk

Replacement Filters
HEPA filters are consumables that gradually load with particulates over time. A replacement H14 HEPA filter for the 2×2 FFU is available so you can keep a spare on hand. The washable magnetic pre-filter extends the main HEPA filter's life by catching larger particles first, so under normal use you'll replace filters far less often than with a standard FFU.
18-Month Warranty
Every Bonsai FFU is backed by our 18-Month Limited Warranty, covering manufacturer defects and workmanship issues under normal use. We engineered these FFUs with upgraded components specifically to provide longer service life and better reliability than lower-cost imported units.
