MELONFARM4 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 12"

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.

It works great for keeping the odor under control

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.

Works great as a filter, but it has an opening at the end of the interior screen that allows the charcoal to fall out if tipping the filter any direction but with the flange up. Had to seal it with duct tape.

great product... would never ask for a refund... if that ever happend/s it must've been a glitch in amazon's system

Build quality equal to ac infinity filter, performed the same, but not good enough for eliminating odor at various speed settings. Going back to the canfilters

Poor quality materials, poorly packed for shipping, item was heavily damaged. I reached out to the vendor and the email was returned because they listed a fake address.UPDATE: had to return the first busted up damaged, dusty unusable filter and they sent another dented up, damaged filter but this one was put in an extra box to try and protect it but There was damage on the original packaging and not the Amazon box, so someone put a damaged filter into a Amazon box trying to hide the same issues. These filters are DIRTY, my home is covered in carbon. avoid these filters and this seller at all costs. Terrible experience, horrible customer service, poor quality products and shipping practices.

I was skeptical of the price but took a chance since I needed a filter. It works great and Shipping was fast. Def would buy again.
