    Introducing our new Polyfil filter disks in a bulk pack of 20, designed to eliminate any guesswork involved in the air exchange equation. These disks are made from a sturdy synthetic fiber that is resistant to water and feature a 3M adhesive back. With the perfect flow rate and density, they enable the right amount of air exchange for monotubs, indoor greenhouses (Martha Tents), or any bulk casing style grow. The disks effectively maintain humidity while allowing for the necessary high levels of air exchange required for any tub or greenhouse. Installation is effortless - simply peel and stick over any hole with a diameter of up to 2.25". The disks can be cleaned using Hydrogen Peroxide and re-used for multiple grows.


    Features:

    • Comes in a bulk pack of 20
    • Each disk is 2.5" in diameter
    • Covers holes with a diameter of up to 2.25"
    • Can be installed in seconds on any plastic container or greenhouse

      A monotub filter disk is a circular piece of material, typically made of polypropylene, that is used to filter the air entering a monotub used in the cultivation of mushrooms.

      The filter disk is placed over the ventilation holes on the top of the monotub and is secured in place with a lid. The purpose of the filter disk is to prevent contaminants, such as bacteria and other airborne particles, from entering the growing environment while still allowing for proper air exchange.

      The filter disk typically has a micron rating, which refers to the size of the particles that it can effectively filter out. The most common micron rating for monotub filter disks is 0.2 microns, which is small enough to prevent most contaminants from passing through while still allowing for adequate air flow.

      The use of a filter disk is considered an important step in maintaining a sterile and healthy growing environment for mushrooms, as contamination can significantly reduce yields and quality.

        We teamed up with Micropose in 2019 to create the original Monotub disk to say goodbye to polyfil! Our disks are rated for proper air flow unlike many cheap knockoffs. We take the guess work out of the air exchange equation with our newly designed Polyfil filter disks. Constructed from a durable synthetic water resistant fiber and 3M adhesive back, these disks have the perfect flow rate and density to allow the right amount of air exchange for monotubs, indoor greenhouses (Martha Tents) or any bulk casing style grow. They keep humidity in and allow for the high levels of air exchange needed for any tub or greenhouse. Simply peel and stick over any size hole up to 2.25" diameter. Can be cleaned with Hydrogen Peroxide and re-used for multiple grows.
