Description

Improve air quality in the grow area with GrowBright CleanFlow HEPA Filters. GrowBright high efficiency particulate arrestance (HEPA) filters remove 99.97% of airborne particles at .3 micrometers. Highly efficient filtration with excellent airflow also makes GrowBright CleanFlow HEPA filters the most effective option for keeping expensive air-cooled lighting equipment clean and free of debris. CleanFlow HEPA filters install easily over rigid duct/flanging and secure tightly with a rubberized collar and steel clamps for a proper seal, and they can also be washed as needed for extended life. Simply remove and spray with a water hose to clean. Please Note: HEPA filters are recommended for use with high-velocity inline fan or blower fan units as they may create too much restriction for smaller fan types such as duct booster or small axial fans.

    • Works, abd very durable.
bought for 3d printer enclosure, works great no detectable increase in pm 2.5 or pm1.0 from 3d prints. This combined with a carbon filter and inline fan, create a negitive pressure for the enclosure. There is no longer a smell when printing abs. FYI I heat my enclosure to 53c so this filter is inside and exposed to that temp for sometimes 15 hours none stop. ... show more

    • Great so far!
I purchased this as part of my mushroom growing hobby. I put this hepa filter on the outside of my tent so that only filtered air comes in. It was easy to install on my blower fan and after about 2 months has worked flawlessly. It's a little expensive, but so are all HEPA filters in my book. I'll purchase this again when the time comes. ... show more

    • This filter is not Hepa rated.
Review Image by JShearer JShearer
Went through 2 of them. Both high particle counts under 1 micron. Almost the same as ambient. Does not seem to actually be hepa rated. Not sufficient for a lab. Great for adding positive pressure, great form factor, but not clean. Used for growing mushrooms.

    • Needs to be cut using razor to fit 4inch
It took a lot of shaving down on the inside lip to get it to slip onto my ac infinity 4inch inline fan. The fit is airtight once you get it to slide in enough but it’s a lot of work if you use a razor blade like I did.
