## 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.

## Questions & Answers

**Q: This seller boarders on the ridiculous. how am i suppose to match an inline fan without knowing the cfm rating of this filter? lol**
A: I have it on a 2 hundred and something fan and it does great

**Q: At what cfm would this filter provide laminar flow? without this info the hepa rating is worthless.**
A: These aren’t designed for that particular application and I am curious as well. I’ve wanted to use one to supply a clean space. I suppose with a speed controller it can be achieved. I don’t know how much it effects it but I would imagine a planar or flat type HEPA filter would be ideal as you’re never going to get air to emerge at a perfectly perpendicular direction from the membrane as the flow is restricted into a vent by design. You could get around it by modifying the area of the channel but by controlling the speed you have the best chance. It’s very heavy duty and performs beautifully for keeping a space clean.

**Q: I'm not seeing a CFM rating (a rather important spec of a filter) ?**
A: I run a 4” 190 cfm exhaust fan on a sealed unit where this is the only inlet for air. There is definitely a good suction in the tent which would tell me that the filter is rated much less than the 190cfm, however it works well paired with this size fan.

No fittiment issues.

### ⭐⭐⭐⭐⭐ Works, abd very durable.
*by F***S on July 18, 2020*

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.
