0.2 Micron Filter Bags

Secure your cultivation success with our premium 0.2 micron filter bags, specifically designed to work best with grain spawn and slow-growing mushroom varieties. During lengthy colonization periods, maintaining a completely contaminant-free environment is critical. Our embedded 0.2 micron filters aggressively capture airborne particles 0.2 μm and larger, providing a strict barrier that ensures only sterile air reaches your vulnerable mycelium.

Manufactured from thick 2.4 mil polypropylene plastic, these bags are engineered for heavy-duty performance. They are fully heat resistant up to 325°F (160°C), making them safe for prolonged autoclave sterilization. Measuring 8" x 5" x 26", each bag comfortably holds up to 6 lbs of substrate while leaving plenty of room for optimal air exchange.

The expertly gusseted design allows the bags to securely stand upright and form perfectly shaped mushroom blocks. Achieve professional-grade results with high-quality bags that cost less, maximizing both your yields and your budget.
