Ventilation Option

Hey guys I was just wondering if you think something like this
Amazon.com: HONEYWELL ENVIRACAIRE HW628 Twindow Dual Window Fan: Kitchen & Dining
would work well to ventilate a room? It has an exhaust and fresh air option so it seems like it would ventilate a smaller grow room well enough.

anyone????

if you are planning on putting that in a window, there are some things you should consider first. A: how is this going to affect your temperature in that room during winter? i've had one of those units myself and wouldn't consider using it in winter without supplemental heat to counteract the cold. B: how are you going to address the smell issue? if you're out in the middle of nowhere, this won't be a problem. otherwise, you had better think of a solution to purify that air.

I was thinking bout just putting it in my wall to vent the flowering room. What are your thoughts on that??? Smell isn't an issue.

How much ventilation would be needed for a 10 x 8 room with a 600w HPS lamp??

I'm growing 8 plants.
