Can you blow through a filter?

Im ordering a 6" Inline fan soon and I wanted to run a spilt hose to pull the air from my flower and veg room then push it through a filter. Ive only really seen people sucking air through a filter, not blowing air through it. So please anything would help!

I think you are talking about a carbon filter. You can blow through them. The reason most people pull air through them is they come with a pre filter wrap which catches small particals and makes your carbon last longer.

I also heard something about a difference in pressure between filter and blower if pushing rather than pulling which may allow smell to escape somehow...not sure tho

what does the kit consist of?
I'm looking to buy one myself in the next few weeks!

You can....but because of the design of the inline blowers...it will be less efficient and COULD lower its lifespan. These blowers are not designed to push, but you can do it. Also, like said above you wont be using your prefilter and it could lower its lifespan.

I'll post it again:

Carbon filters work by trapping airborne particles in the pores of the activated carbon inside the carbon filter. You need to draw air through the outside of the filter (passes through the carbon) and then out through the internal exahust of the filter itself. If you can vent outside, do so, as it creates negative pressure in the room which can be used to pull in fresh air from elsewhere. You have to make sure your fan has enough power to draw correctly without too much of a static load as well. Open to debate I suppose(for some) but most would agree it's best to pull clean air out of a carbon filter, than push dirty air through it. Why? Because air that hits the fan blades that has been 'scrubbed' already has less particulants to stick to the fans blades, possibly slowing it down or throwing it off balance. If you PUSH the air through, the air is still 'dirty' and likely to contain a higher amount of particulants. Common sense, really.

Im paying about 200 for both 6" Inline Fan and 6" Carbon Filter. But I guess I'll Just run the filter in the flower room and run that through a cooltube and just figure out another way to exhaust the the vegg room
