works as advertised

This review is for the 12" by 39" filter. The product And the shipping box arrived absolutely destroyed. The filter literally almost fell put of the box because it began to fall apart as I tried to rush out of our local post office with the huge box labeled BLACK OPS CARBON FILTERS as I could feel every single persons eyes glued to the back of my head as I struggled out of there. I am simply appalled at the lack of ANY shipping foam being used in the shipping container. It was so bad I took a picture of everything that protected the filter through shipping. It's nothing but a cardboard box. I couldn't even force an inline fan onto the flange because it was a deformed oval. Like anyone is actually going to try and return something like this. This is absolute thievery. And because of their shipping container it is clearly evident they are aware of it. I spent the last 2 or 3 hours beating it into submission. And another 30 minutes duck taping both the flanges back on and another 10 minutes to duck tape my inline fan onto there... And yes, I did buy a flange specifically to mate the two together so I didnt have to do something like this... So Yes. I am upset.

Just as good, if not better than all the other high priced filters out there. I use this in my tent with 6 plants (Tent is 8X8X10.) This thing has been going hard for 6 months, and right next to the vent there is hardly any smell. It definitely works and won't break your bank like Phresh or CAN filter would.

If you’re worried ab discreetness this is not the product, comes shipped in a box with huge stickers on the sides showing pictures of it and it’s features

I bought a 10in and a 12in and the built in flange doesn't fit the inline fan on either one. Horrible design flaw on that. Had to bend the flange back on both just so the fans can sit awkwardly on top. Other than that they seem to do just fine.

I use the 6 x24 inch in a 3x5 grow and it works great. I used to be able to smell it at my mail box before I had it. Now i can barely smell when I'm in the same room. This thing is amazing

I would definitely recommend this filter, mine arrived without a single defect, quality is definitely noticed as soon as you un-box it. I use mine with a 6" Vortex S-line fan and it mates up to it with out any ducting required. The flange on this filter is about 6 1/4" in diameter so slipping a 6" ducting will not be possible without rigging something up. My only complain was the packaging not being discreet. It definitely shows the world what's inside.

No smell on the output. Impressed. Not like the cheap ones that are missing some carbon which lets are threw without filtering. Thus one is great.

I dislike that I could not purchase 6 x 16 bulk ops carbon filter for a small grow tent.I like the reviews on this product.

ok
