Bought a 6 pack a year ago or so, I just peal them off the tub afterward and clean them and the tub for the next round. I just tore the adhesive off of one accidentally.

No more poly fill to deal with. These stick on filters are awesome. So many uses beyond monotubs.

Work great!

Picked these up to use on my Ecosphere set up to improve gas exchange throughout my grow process. The air quality inside the tent smells fresher without reducing my humidity or affecting temperature in a meaningful way.



I love being able to just buy what I need and trust that Midwest has done the homework for me :)

These things are great! They are thick and durable and they stick like grim death.
