Engineered for optimal airflow and contamination defense, these discs simplify fungal cultivation by eliminating manual adjustments while maintaining moisture and blocking impurities. Each pack includes six durable, easy-to-apply filters trusted by growers for consistent, healthy fungal growth. ## Description Myco Labs The Microppose Original Synthetic Polyfil Monotube Adhesive Filter Discs is a product innovatively developed in 2018 through a collaboration with Microppose. These filter discs are cut to fit mushroom monotube breeding chambers, which typically feature six airflow holes. The package includes six self-adhesive filter discs each measuring 2.5 inch diameter, perfectly suitable for sealing holes up to 2.25 inches in size. Designed for optimal density, these discs ensure the right airflow rate to promote healthy fungal growth. There is no need to manually adjust or calibrate the airflow; users can simply peel off the filters from the back and attach directly via the air holes in their monotube chambers. This easy handling ensures that fungi receive the necessary fresh air exchange (FAE) for optimal growth and maturation. In addition, these filters act as a protective barrier against foreign spores and contaminants, protecting your gourmet fungus and minimizing the risk of contamination. Review: Adhere even to thin plastic - These filters are sturdy and adhere well even to thin plastic. Using an exacto knife, I cut 2" circular holes in the plastic sides of a Magoog still air mushroom grow box and then affixed a filter to each hole. The filters adhered tightly and appear to be functioning nicely in providing more air flow through the box. Review: Great Filter Disks and Outstanding Seller! - I recently ordered these filter disks, and they work just as expected—sturdy and effective. They’ve been doing the job perfectly, and I’m really happy with them. But what really made this purchase stand out was the seller. They were fantastic from start to finish—quick to respond to my issues, super helpful and responsive, and they made sure the disks arrived on time and in great shape. It’s rare to come across service like this. If you’re on the fence about buying these, go for it. The product is solid, and you’re in good hands with this seller. I’m definitely coming back for more when I need them! ## Features - Adhesive design: each filter disc comes with a peel and stick function for easy application - OPTIMAL SIZE Discs are 2.5 inches in diameter, ideal for covering air holes with monotubes, up to 2.25 inches - Simplified use: eliminates the need for manual adjustments or calibration compared to using polyfil or filter tape - Protective barrier: acts as a defence against foreign spores and impurities, ensuring the health and safety of fungal cultures - Keeps moisture in and impurities in the air out ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.6 out of 5 stars 219 Reviews | ## Images ![Myco Labs Microppose Original Synthetic Polyfil Filter Discs 2.5" Single Tube Self Adhesive (Pack of 6) - Image 1](https://m.media-amazon.com/images/I/71qHkpBxfjL.jpg) ![Myco Labs Microppose Original Synthetic Polyfil Filter Discs 2.5" Single Tube Self Adhesive (Pack of 6) - Image 2](https://m.media-amazon.com/images/I/61mrW8kMDRL.jpg) ![Myco Labs Microppose Original Synthetic Polyfil Filter Discs 2.5" Single Tube Self Adhesive (Pack of 6) - Image 3](https://m.media-amazon.com/images/I/71ZitqmL0uL.jpg) ![Myco Labs Microppose Original Synthetic Polyfil Filter Discs 2.5" Single Tube Self Adhesive (Pack of 6) - Image 4](https://m.media-amazon.com/images/I/51JGSWVm3sL.jpg) ![Myco Labs Microppose Original Synthetic Polyfil Filter Discs 2.5" Single Tube Self Adhesive (Pack of 6) - Image 5](https://m.media-amazon.com/images/I/71uI9fDAYUL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Adhere even to thin plastic *by J***N on 22 February 2025* These filters are sturdy and adhere well even to thin plastic.

They’ve been doing the job perfectly, and I’m really happy with them. But what really made this purchase stand out was the seller.

I’m definitely coming back for more when I need them! ### ⭐⭐⭐⭐⭐ Great FAE Quick and correct tek. *by B***C on 4 August 2024* These stickers are amazing. I have used them on Gourmet/Supplement multi tub settings and they worked with Reiki, Cordcpts, Oyster barrel runs that I used a Martha tent and just didn’t put any shelves in ;-)…..but I literally depend on these for quick controlled environmental FAE introduction, increases, stages of FAE and they require a simple properly isopropyl cleaned scalpel or new razer and if plastic tub a nice sharpened Gerber Gator on Benchmade (Temu for budget conscious friends) and use it solely for square(stickers are circle but best practice in my opinion is to cut a 2.5x2.5 or 3”x3” maximum square and you will see that the coverage would not work if you try anything larger or not square. But the best parts for those who have multi tub controlled RH/Temp and a light inside the tub (the Amazon mushroom light bulb for 8.95 is 1000% the best choice due to the fact it is small straight 4”L and. 1.5” In diameter glass enclosed LED light array with a venting system in the glass and it comes with a socket connector. For these stickers they are so well made and thick, if you cut a 3inch slit those bulbs can be simply slid into the tub with no micropore tape needed due to the strongh of the makeup the stickers they will seal that bulb and the socket like Magic stays on the outside. I use WiFi 3 port surge protectors and run a singe 6foof Extension cord to the socket plug and use the WiFi surge protectors app and run theee lights that would not be possible IMHO without this product. This is literally second or third revue and I only am doing this to hopefully help You make the correct decision; you will love these. ## Frequently Bought Together - Myco Labs Microppose Original Synthetic Polyfil 2.5" Monotub Adhesive Filter Disks (6-Pack) - Myco Labs Premium Bulk Mushroom Substrate Mix | Fully Pastuerized | Maximum Yield | for Dung & Grain Loving Mushrooms (5 LBS) - Myco Labs Premium 5-Grain Mushroom Spawn Bags | Sterilized Grain Spawn | Injection Ports | 2 Quarts Each Bag | 2 Bags per Box --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.cy/products/784392051-myco-labs-microppose-original-synthetic-polyfil-filter-discs-2-5](https://www.desertcart.com.cy/products/784392051-myco-labs-microppose-original-synthetic-polyfil-filter-discs-2-5) --- *Product available on Desertcart Cyprus* *Store origin: CY* *Last updated: 2026-08-22*
