Monotub Adhesive Filter Disks – 20-Pack

Effortless Airflow. Maximum Protection. Reusable Convenience.

Say goodbye to polyfil and guesswork with our original Monotub Adhesive Filter Disks, now available in a cost-saving 20-pack. Developed in collaboration with Micropose, these filters are custom manufactured to deliver optimal airflow and humidity control for monotubs, Martha tents, and bulk casing-style grows.

Each 2.5" disk features a water-resistant synthetic fiber construction and a professional-grade 3M adhesive backing, making them easy to apply to any hole up to 2.25" in diameter. Whether you’re dialing in airflow for colonization or maximizing fruiting conditions, these disks strike the perfect balance between gas exchange and contamination defense.

Key Features:

  •     20 premium adhesive filter disks per pack
  •     Durable 2.5" synthetic fiber construction
  •     Covers vent holes up to 2.25"
  •     Strong 3M adhesive backing
  •     Reusable—just clean with 3% hydrogen peroxide
  •     Ideal for monotubs, Martha tents, or any bulk casing setup
  •     Designed for consistent, reliable air exchange

Clean, stick, grow, and reuse—these disks are built for multiple cycles and trusted by cultivators who demand consistency and control in every grow.

Why are you not using these ?

Excellent FAE Exchange, Easy to Replace, Great Price

I find these are super easy to use and replace. I do not have to worry about FAE and can use a humidifier either internal or external and not worry about the filter disks clogging or not allowing fresh air in. I highly recommend this product.
