Question on exhaust inline fan combos

[shorty011]

I'm trying to find out info on exhaust inline filter combos made by a company called growsun has anyone heard of them know anything about them are they good products or stay away ?

Growsun is an alright combo. That brand reminds me of the first vehicle the parents buy you and its just a beater with a heater, no good lol. Anyways, theyre too loud, as in the motor that drives the fan is too loud. And the carbon filter they make doesnt last 6 months. I recommend Ventech inline fans with a Phresh Carbon filter. I have the 4" ventech inline fan and this thing is smooth running, it is loud but its loud because of the air it pushes, the motor is quiet. High quality for 50 dollars on amazon. I have the 4" x 12" Phresh filter attached to the fan. I have been running the same filter for 3 years next month and it still works as if i just bought the thing yesterday. Only thing i had to do to the filter was clean off the dust sleeve that goes over the filter. If you want the combo to be much quieter i would get the ventech duct muffler that attaches to the inline fan. The price for all 3 costed me 210.

I used a couple 6" can fans mated to black ops filters. Work great and super quiet.
