4 Inch Air Carbon Filter Smelliness Control with Australia Virgin Charcoal, Odor Removal Carbon Filter for Grow Tent, Inline Fan, Hydroponics, Pre-Filter Included, Insulated Flange 4" x 11"

I use this in the winter to purify and deodorize the house in the winter. The air can feel pretty stale after being stuck inside all winter. I just connect this directly to my blower and run it in whatever room needs it. Truly feel like it cut down on our sickness and made the air feel light and fresh! Throw a dryer sheet on the output side and it smells like spring all winter.

So far seems good. I don’t even need to use ducking with this. I have it connected directly to the in-line fan and this just sits right on top of the tent. My set up is so small and this is such lightweight. It works great. It doesn’t prevent airflow issues. It doesn’t stop the suction from the exhaust fan. The degree of pressure that comes out is the same. It’s just filtered which is ideal for gardening and I was surprised that the function for how inexpensive this was I definitely recommend it.

Bought to use on my laser engraver so i can have the window open. So far its working great! Cant smell anything more than i did with it vented out the window using a dryer vent. Infact it might even smell less. So far im engraving coated stainless flasks. Havebt tried it with cutting or engraving wood. Kinda curious to see how well it will work or not. Works extremely well and i cant imagine paying nearly double the price would get any better performace.

For the price yah can't beat the value and in a pinch worked wonders! Easy to set up and filters perfect! Just keep in mind the humidity levels matter with these things!

Does what it's supposed to do

GOOD PRODUCT

I have used this filter now for over a year in a 4x4 tent. This completely prevents any smell from getting outside the tent. Better price than the others and worth it.

If it lasts a little while, seems like a great deal. Compact enough to get inside of a little tent if you need it, although I would probably just run it through the outside It has plastic top and bottom so try not to drop it.

De momento funciona bien, lo ocupe para una máquina de ventilación de láser.
