Microppose For 1" Holes, Adherable Tub Filters

These are exactly the same as the Microppose 2” filter patches, except - guess what - they’re 1”. 

You would use the 2” filters to cover up a 2” hole on your monotub. You’re now thinking “okay so I guess the 1” ones are to cover up a 1” hole” and you’d be dead right. Nice, straightforward product naming.

Microppose have made mushroom cultivation stuff for a long time now, and if they think that people need 1” filter patches, then we’re inclined to agree. The quality is the usual Microppose levels of “awesome”; we used to use their patches on our old monotubs, before we started stocking new Microppose Monotubs and retiring our own version.
