It works, unlike the hood they sold with it....

I’m sure it works great I haven’t hooked it up yet

A whirlwind effect that it creates I may not need side fans . Now with so much volume of air moving will have to think of tent braces to keep sides from collapsing inward using a 440 cfm in a 2'x4'x6'-11" I know over kill but I can run it on lowest setting somewhat quiet, fan for lights are louder than it is and the filter baffles the blower

I was completely amazed at how well this unit works to purify the air, and how quite this unit operates. Send me a deal on the whole package and I will buy another one.

Combined with the companion fan, it is doing a fine job of scrubbing the air and vacating humidity. The only knock on the filter/fan combo is it’s bulk. Other products might occupy less space in the tent. Would I purchase this again? As of now…the answer is yes.

Works great. Keeps humidity down and filters out the smell In the air.

This is the best air filter I bought so far! It cleans the air, no odor coming through the vents at all! The carbon layer does it's job without compromising the rate air flows out the vents. This is a keeper!

I bought this a couple months ago and so far it has worked perfectly for me. No odor coming at all. It's been a wonderful surprise indeed. I'll be ordering some more to replace my old ones. Way to go Yield Lab.

I waited on making a review after doing a few grows with this filter. This is just flat out amazing! I have a 4 x 4 tent and this does the job easily.

I love how GrowAce packed and delivered this item to my doorstep. Everything was great, no damages at all. Installation was easy as well, and this product works EXCEPTIONALLY! No odor at all coming out of the tent. My only gripe with this is that some of the charcoal dust came out of the item during shipping.

This filter works great as advertised, no complaints at all. The carbon filter really helps zero out any odor coming out from my grow tent which makes me really happy. Easy to setup and install, definitely a must have!

I was really disappointed when the package came in as there were a lot of charcoal powder in the box. I just wished this was indicated on the listing.

The product delivers what it promises, no odor coming out from my air vents at all. I just didn't expect it would be a little messy to handle the filter with all the charcoal.

One of the best filters in the business! With it's price tag, this is a no brainer for any indoor grow enthusiast like me. This filter does make sure no foul smelling odor goes out of your tent exhaust. Very well made and I'm definitely loving it.

I was half expecting a cheep, flimsy filter with a screen and was pleasantly surprised by the weight a hardiness of this filter. Yield labs makes great products and this filter is no different. It has great airflow capabilities and brings smells down to zero.

very good product best ever

This filter works wonders for my indoor grow setup. I have tried other brands but it does not perform like this filter does. The charcoal absorbs and performs really well in cleaning the air before it gets out of the exhaust. I'm very satisfied and can't wait to get more in the future.

I was really excited to get the package as I was needing to replace the filters I was using. It did arrive in time (actually a day early), but I was a little disappointed that there were a lot of carbon dust in the box when I opened it. The filter looked dirty because of it. Apparently, it does happen especially when the box is shipped all the way to the east coast.Having said that, the filter is superb! You could not smell anything from the air coming out from your tents. It's like breathing fresh air even. I'm pretty satisfied with what I bought with the tiny exception of the carbon dust in the box.

In my opinion, this is the best air filter in the market! Easy to mount and install in your grow tent and it really gets the job done.

It was a risk for me to make this purchase with GrowAce.com as I have never heard of them before, but I was wrong to worry. The package came in great condition, and the item was properly packed. The filter is excellent, you can barely notice any odor coming out of your vents with this installed. This was an unexpected great product from a reputable company! I will definitely be coming back for other grow needs!

This is an amazing product! I've had many filters and by far this is the best. It works as advertised, cleans and remove odor from the air before it gets out your tent. I'm pretty impressed how this performs and I am loving this!

I'm surprised how quick my filter arrived and how perfect it is to clean the air coming out of my grow tent. I can smell nothing coming out of the vents after I installed this. This is just great!
