I'd been wondering how to assure proper air circulation. These filters are perfect.

Self stick makes for a no hassle install, they'll keep the air refreshed at the correct rate.

These filter stickers make working with monotub simple. It is much cleaner and effective than stuffing free flowing polyfill into your holes. I would highly recommend this product!

Great product

I really like these stick-on vents; nice and gf convenient. Only place I could find what I wanted was from Midwest.

I just called and talked a woman's ear off with questions, but I'm just amazed at the quality and professionalism from this company. I only ordered these to get the free shipping, but now I know what I can do for future grows!



11/10 company.
