  • Great for winter use
Size: 4"x11"Fifer
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. ... show more

  • A must have product for your grow!
Size: 4"Fifer+Fan+Ducting
I was extremely surprised how strong the fan was being that it was built in and a lot smaller than the other 4-in fan that I purchased. With that being said it is about twice as strong as the other setup that I have and if I would have known that to begin with then I would have just purchased these from the beginning. With that being said I highly recommend them and they are very efficient and simple to use. And it also you can use it for intake or exhaust. Just flip it around and that will either breathe in or breathe out the airflow. It's a little bit louder than my other device but that's okay because the event fan is traveling a distance and also with curvature so I believe that's what's making a whistling noise. The carbon filter reduces the smell so it works very good! The only issue is I only have one of them , not four! LOL ... show more

  • Pretty impressive little filter
Size: 4"x11"Fifer
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. ... show more

  • good deal
Size: 4"x12.6"Fifer+Fan
Gave 4 stars because I have no idea how long it will last. Air flow is surprisingly strong. I have it on the lowest setting and that's plenty enough for a 3 × 3. Noise is no louder than any other fan this style. If it lasts this is a definate 5 star because of the price, quality and effectiveness(smell contained). ... show more

  • Best bang for the buck! Strong fan! Best bang for the buck! Strong fan!
Size: 4"x12.6"Fifer+Fan
Ive used other more expensive 4" inline fans in the past for plant smells, but I bought this for a different purpose.... To remove soldering fumes. This fan is way better than the other 4" inline fans ive used, this has a very powerful high static pressure fan that really moves some air! Can control the fan speed with the dial/ potentiometer on the power cord. I opened the flange end to reverse the fan so that it sucked air in. Theres alot of loose carbon to clean up on initial setup but this thing works fantastic and has more power than more expensive fans. This fan/filter combo is also curently the cheapest option and works great so get it if your looking! ... show more

  • great product works great for dual room grow tent! great product works great for dual room grow tent!
Size: 4"Fifer+Fan+Ducting
This worked perfect rite out of the box and into the tent! MELONFARM FOR THE WIN! Brought temps down in my veg and clone side of the tent perfectly has a prefilter on it just haven't put it on as of yet. For the fan it self it works great has a great adjustment knob that you can change the speed of the fan to suit your needs. On full blast it is just a touch loud but it is manageable to deal with. all in all this is well worth the money! by the way this one is good for a 2x2 or 3x3 at max. hope this helps anyone in the fence about buying one. i know im getting the larger 6in for sure when i need a new filter on the other side of my tent! :) ... show more

  • Very disappointed. Past return window
Size: 6"x11.8"Fifer
We bought a whole new set up on Prime Day in July and purchased this as an extra filter to have on hand when that one was ready to be replaced. Put this one on a couple days before Christmas because the other one had reduced air flow after 6 months of use. Big mistake. This thing absolutely does not scrub the air at all. We had odor in the room it was used in and mildly even in the hallway and stairwell. We couldn't get it to go away. Never had an issue before. It's the new filter. Useless garbage. And past the return window because I bought it on sale on Prime day. Never again will I try an on sale off brand. It didn't save me any money at all. ... show more
