2.5" Monotub Adhesive Filter Disks – Professional-Grade Filtration (24-Pack)

Precision Air Exchange & Contaminant Control Engineered for high-performance monotub systems, these 2.5" adhesive filter disks maintain ideal gas exchange parameters while effectively filtering out airborne particulates, spores, and dust. The balanced air permeability promotes vigorous mycelial respiration and stable humidity within fruiting environments. Laboratory-Grade 2mm Filter Media Constructed from a 2mm-thick, nonwoven microporous fabric with uniform pore distribution. The 0.2" adhesive perimeter ensures an airtight seal around monotub ports, eliminating unfiltered leakage. The material’s optimized density supports proper FAE (Fresh Air Exchange) without desiccating substrates or compromising sterility. Tool-Free Installation & Maintenance Each disk features a peel-and-stick backing for direct application to 2.5" air ports — no silicone, glue, or clamps required. The industrial-grade adhesive holds securely under high humidity and elevated temperatures yet removes cleanly for quick filter replacement between flushes or cycles. Bulk 24-Pack for Continuous Production Includes 24 monotub filter disks suitable for multiple monotub builds or frequent replacements in large-scale cultivation environments. Ideal for cultivators maintaining multiple fruiting chambers, research labs, or commercial grow operations. Universal Compatibility Designed to integrate with most standard monotub configurations, mushroom fruiting chambers, and colonization enclosures. Equally effective for passive filtration in spawn incubation, grain spawn chambers, or high-humidity grow environments.
