13" × 15" Laminar Flow HEPA Filter

Yes. The 13" × 15" filter face produces a clean air zone large enough for pouring agar, grain-to-grain transfers, and liquid culture work. For larger projects, the Model 4 (24" × 24") or Model 3 (24" × 48") offer more workspace.

The Model 1 uses the AP1518 replacement filter, which is commonly available. We also sell replacement HEPA + carbon pre-filter kits directly. The removable retainers make swapping the filter a quick, tool-free job.

You can — and many hobbyists start that way. But a still air box relies on calm air, which is disrupted every time you move your arms. A flow hood actively pushes HEPA-filtered air across your work in a smooth stream, providing dramatically better contamination control and a much faster workflow.

Absolutely. The Model 2 Bio Hood is your Model 1 mounted on top of a 24" × 24" × 24" positive-pressure cabinet with a viewing window. The base cabinet is available separately for $275, so you can upgrade without buying a second filter unit.

For hobby use in a reasonably clean room, 1–2 years is typical. For heavy daily use, 6–12 months. The blower motor itself is rated for 60,000 hours — approximately 15 years. Clean the pre-filter monthly with a soft brush or vacuum to extend the main HEPA filter's life.

When you purchase a Model 1, a 15% discount code is permanently activated on your customer account. Use it on any Mycology-Supply agar products, as many times as you want, forever.
