Microppose Adhesive Tub Filters For 2" Holes

You know the filters you get on the end of a cigarette? Nothing like this.

These filters can be applied to your fruiting chamber to give your substrate fresh air while maintaining high levels of humidity. These filters are slightly larger than your 2" tub hole and are designed to cover them with a bit of overlap so it sticks nicely. Peel the backing off, stick it on, done.

There are a few “big names” in the mushroom cultivation industry, and Microppose are absolutely up there. Top quality products designed specifically for anyone who’s interested in the science of mycology. At MycoPunks HQ that’s what we use, because quality’s important - we even used them on our own Tek Tub Starter Monotub before we replaced that with the nice new Microppose Monotubs!

✅ High airflow filters

You could muck around with Poly-fil, micropore tape and those sorts of things but really for this price you’d have to be fuckin’ MacGuyver to want to spend your time like that.
