Nkiy Quen 24 Pcs 2.5" Monotub Adhesive Filter Disks-3MM Thick Monotub Filter Discs-Monotub Filters for Mushroom Growing Supplies Filter Pad Replacements

Work great as intended. I didn't have any problems with the stickiness as other mentioned. I've bought other brands and these are just as good

Do exactly what they are supposed to do. Well made and excellent adhesive.

Does the job

So easy to use. Beats polyfill.

They're just filters, so theyre hard to mess up...I wish they wouldve shipped them more descreetly instead of shipping them in a clear zip lock baggie...Would buy again

I use 66 qt monotubs for growing gourmet mushrooms. The filters maintain the sterile conditions very well, while allowing free air exchange. This is crucial for fruiting conditions. These definitely save time and can be re-sterilized in a pressure cooker at 15 psi for 30 minutes.

Works great…sticks well

Super easy to use and reusable! Just pressure cook for a quick 15min and you'll be good to go!
