3" Adhesive Monotub PTFE Membrane Disc Filters
Hole size | 3 inches |
Filter size | 90 mm diameter |
These high airflow, ultra-thin filters give your substrate and mycelium fresh air while maintaining high humidity levels. Manufactured with a strong adhesive backing, these filters are made from PTFE membrane material and sized to fit over 3" holes. Filters are slightly larger than monotub holes and are designed to keep out foreign spores and other contaminants. Use them in place of polyfill for time savings, fast application, and better protection against unwanted contamination.
To reuse: Clean with 3% hydrogen peroxide solution, being careful to avoid adhesive.
PTFE membranes have a filtration efficiency of 99.97% for particles as small as 0.3 μm.

These are high quality micropore filters, perfectly sized for the monotub. Very easy to apply, and very sticky. You won’t have to worry about them falling off!!
