Review: Fyi - Works great just measure twice
Review: Fits my grow box perfectly. - I bought a FUNGISMILE Grow Box and was missing the air filters that the manual shows. Lousy customer service refused to send them. This seems to be working as I checked after the first fruiting and they looked good and are now being used on the second fruiting. Very affordable. Easy to apply. Fits perfect. Debbie
