## Questions & Answers

**Q: Can you add a carbon filter**
A: I'm using it with a 4" carbon filter in my veg/mid  flower 2x4 tent. Airflow is pretty reasonable coming out of the end and the air is scrubbed good with a clean fresh smell. I'm here because I'm buying a second one to use as an intake fan to complete the setup. I'm only running 1 95 watt light in this tent so I don't need extreme airflow. In my 3x3 flowering tent however, I  am running the ac infinity cloudine 4" fan with the ac infinity 4" carbon filter. More lights and more smell equals more airflow needed.
These are a little bit on the louder side compared to the cloudine so if that doesn't bother you then you'll be ok. You'll need those running at full speed with the carbon filter. I run my cloudine at half speed. 
If you're looking to save some money then it will do the job but the cloudine is the one to get otherwise. 
I'll probably get another cloudine in the future for my veg tent but for now this will be ok.

**Q: Will this plug into T8 digital temp and humidity control?**
A: I use it in my tent to exhaust air out and have it in a timer, but you can def plug it into an environmental controller.

**Q: I need to run at approximately 190 to 200 cfm. Would it be quieter to run a 6 inch at high speed, or an 8 inch at low speed to achieve this flow?**
A: Go with the 8 inch which will move more air at lower speeds. Higher speed it becomes a small wind tunnel and is loud..

**Q: can this fan be used on the end of a hose connected to an engine exhaust pipe to help get the exhaust out of my garage?**
A: Usually when you are venting a car exhaust you would hook the hose directly onto the tailpipe and then vent it outside. The force of the exhaust would not need a fan. You could put this fan above that area and suck out any air that you do not want.
I have mine hooked up basically for the winter time to suck the hot air around my furnace and heat another room in the basement, and it works great.
