Features

  • TerraBloom premium carbon filters have industry leading 1.8 (46mm) deep carbon bed that is at least 20% thicker than competition. Our filters scrub air better and have longer lifespan.
  • We use only highest grade, granular Australian activated charcoal, which gives you better adsorption and superior carbon porosity to capture odors, VOCs and other airborne pollutants in growing, laser engraving, food processing and manufacturing applications.
  • This charcoal scrubber can be installed both inside and outside the grow tent and is capable of filtering air in both directions. Whether you want to use it as an exhaust or intake. You can pull air though the filter and out or push air into the filter and out of your grow room, it will work just as well.
  • 4 x 12 inch model has a gross weight of 7.3 lbs and contains 3.9 lbs of carbon inside. It can handle airflow rates up to 350 CFM. For seamless operation pair this filter with TerraBloom 4 EC Fan, model ECMF-100.
  • Recommended for small to medium grow tents with footprint of 2x2 ft, 3x3 ft, 4x4 ft or cultivation rooms of similar size.

  • Perfect
Works great just as described
Reviewed in the United States on January 1, 2023 by charlotte fortner

  • Their are cheaper alternatives - but this filter works great so far
To be honest, I was a little POed when this filter arrived. Something punched a hole in the box that I found had actually put a dent on the side of the cylinder - I forgot all about the dent but just got POed again thinking about it as a write this! Anyway, I decided there was a chance it happened in transit and I didn’t have time to deal with a return so I got it setup. I dig the black sock for the filter and find it gives a more discrete appearance. My hands did get all black while installing the sock. It seems the carbon was falling out of the filter which I don’t know if was normal or not since this was my first filter install. Hoping it doesn’t crap out early given its price. I’m using a 4” fan to pull air through this 4” filter and it works well to eliminate odor on my grow with minimal air flow, which speaks to the scrubbing quality of the filter. Pleased with the performance even though it came dented (🤬) and is a bit on the expensive side compared to its competitors. I would recommend it for anyone who cares about the look of their filter and wants to eliminate most scent in their small space. ... show more

This 4” filter works perfectly for my 3’ x 3’ tent. I had to fabricate a way to suspend and attach it which was easy. Very pleased

Very happy with this filter. They all look the same when shopping online so you hope to pick a good one. Included in the box are two washable pre filters and I can tell you first hand it works perfectly!!

  • Middle of the road.
Works ok keep CFM at least 50 to 75 below what its rated, or you'll be disappointed.

It works like a charm! I literally can put my face in front of the fan and there is zero smell! Before this filter my whole house smelled! Would purchase again!
