## 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: what CFM is your fan rated? for those who it worked well**
A: It works way past most cfm ratings for 6" fans. As this one isn't removing smell, the filtration for particles and bugs works very well

**Q: Will this reduce the sound on the outside of my house from the inline fan running?**
A: You would want to get a noise reducer clamp for what your looking for. This has a rubber insulated coating and a good metal clamp. It might do the trick. But this is for clean air to come in

**Q: How long does the filter last? Is it able to be cleaned**
A: We have been using it for at least 3 months. I am just starting to see some lint on the surface.

**Q: Washable? And if it’s not, what’s the longevity ?**
A: I emailed the vendor to ask got nothing in response. I used mine heavily for filtering smoke but the area was also dusty so life was short. As such likely won't buy again

## Customer Reviews

### ⭐⭐⭐⭐⭐ Excellent
*by S***R on April 8, 2025*

As advertised

### ⭐⭐⭐⭐⭐ Knocks down pm1 pm2.5 out of the air, for smoking room.
*by F***S on July 18, 2020*

I smoke, and with covid I work at home so I wanted to be able to smoke in my office. I installed this filter along with a carbon filter and duct silencer and 6" inline fan. All parts on Amazon. The air flow drop was lower than I was expecting. My pm 2.5 outside the office never gets above 170. Before the pm 2.5 would be 600 or 700 outside the office if the door stayed closed.I confirmed the air coming out the carbon filter is indeed 170. Inside the office the pm 2.5 was off the charts well past the 1000 limit on the meter. Also before woth this being an basement office I was measuring pm 2.5 upstairs. Now it drops off half way up the stairs.This system works 100x better than the honeywell hepa system.After months of smoking daily in my room I am able to see dirt and measure a slight reduction in intake. Still doing well at trapping smoke particles.

### ⭐⭐⭐⭐⭐ Airflow much better than expected
*by J***7 on June 9, 2021*

Airflow was surprisingly good. I was expecting more constriction being a HEPA cone, but air output was more than acceptable. Make sure you use an appropriate sized filter and fan rated for your cfm needs. I used a 6” filter and a 420cfm fan and it does a great job for a 5’x10’ space. Use two filters and two fans to equalize intake/exhaust pressure. Fan noise is noticeable on the output side and may need some muffling like a duct silencer if noise is a concern.
