4 Inch 193 CFM Inline Fan+Carbon Air Filter+Variable Speed Controller+25-Feet Air Ducting With 2 Clamps Combo

This package is a GREAT value. I have not seen anything close on Amazon or anywhere. The quality of the fan and filter are as good if not better than more expensive products available. In addition you get the get a fan switch, 25 ft of ducting with clamps PLUS a roll of Ducting Tape too! And the customer support of G-LEAF is the best I have ever experienced on Amazon, Every question or email is immediately responded to and they will do whatever is necessary to make sure you are satisfied. I highly recommend them for any purchase! Also, most times components of the same diameter will not directly connect to each other, so additional reducers or connectors are required. They can usually be found at a local hardware store and are most times pretty cheap. There are many options for connecting ducting as you can see from my photos below.

Excellent product for the price! Customer service is extremely great! Had a minor rattle in fan and they replaced it immediately and the replacement works flawlessly after thorough testing. Highly recommended and will be making more purchases from this company again! Eager to see new products!

Everything comes as described, works great. To avoid the rattling fan noise, just place the filter on the floor standing straight up and attach the fan. Works perfectly. It was nice to get everything I needed in one place, cheaper than I could seperately. Thanks!

Very strong and quite love it .l have not used the carbon filter yet ,so far so good .

Fan isn't as powerful as I would of liked, and if you mount it then it's pretty loud. Filter is nice and do have the option for bigger fans.
