Question on pushing air through carbon filter outside of tent

Yeah ok. I’ve done it a shit load of times. Wash it from inside out flushing dust and whatnot. Then let it set out in the sun for a day or 2 then bag it for the next time I use it.

Lol...you might get some dust out of the outer surface but your really just wrecking your filter...its not a K&N dude

So you’ve tried it then and you wrecked your filter? Wow you must get shit filters then.

No I know you cant wash out a carbon filter, nor would I tell anyone too.

You'd be better off trying to clean it with compressed air than water...

You can put the prefilter meant to cover the can inside before hooking up the duct to it.

And without a prefilter they get clogged quickly. But you can extend filter life by knocking and shaking the can. Looking to hear loose carbon inside. This exposes more unused carbon.

Nice, I'll give this a try, thanks.

Loose carbon is no good. If you can hear any shaking around the filter is junk. The carbon must be packed or else air will simply go around it.

Advice is from the phresh filter website.

I would rinse the carbon filter out real good with high pressure water. Then let dry completely before use. You could also dry it in an oven if it fits. And if the prefilter doesn’t have much surface area it will restrict your flow also

If high humidity hurts carbon filter performance would wet carbon be neutralized? I think yes.

Still bad advice...

I have vacuumed out dust from a phresh filter and it went from clogged to working well again.

It was white dust from tap water and a sonic humidifier. A lot of dust. I use ro water now. Lol.

No. It has enabled me to get 2.5 years like the website says is possible. No weed smell when replaced from my perpetual flower room or drying closet.

Odds are the filter wasnt spent to begin with. Banging on it to expose unused carbon is BS

I ran a Can75 for 5 years continuosly before I replaced it...it was still filtering out odour when I did replace it but after 5 years, it didnt owe me anything.

Can filters have pellet carbon. Phresh has granular. Shaking the granular carbon up allows more air to pass through unused carbon.

And no carbon filter could stand the 24 hour 12 month a year continuous use I need for 5 years. It never gets a break like from a veg cycle.

You don’t run it wet.

I understand that. The point is it would be rendered useless. I believe you have to heat the carbon to reactivate. Pretty sure that’s what the diy Growers do.

Granular..pellet...same shit different pile. If the carbon can move inside the filter air can bypass the carbon...think about it. Empty space is a leak path. A leak is a path of least resistance.

So do you guys all agree that 8" is plenty to give an 8'x4'x78" tent complete odor control? If the problem is the filter than I will go from there. But if it simply isn't enough, providing degradation of air flow from dust filter, 90 degree elbow, 3 feet of duct and carbon filter than I need to up to 10". Where do you feel is my problem?

You do realize activated carbon is used in water right? Water doesn’t ruin it or nutralize it. The high humidity thing has nothing to do with water hurting the carbon. It just means that smell is harder to filter out with high humidity

and to reactivate carbon it takes more heat the a diy could do

You should stop buying cheap filters. Get yourself a quality Canadian made Can filter.

It hardly moves dude. You can only hear outside grains moving along the aluminum.

I will stick with my research and the website instructions.

The can light filters have the same tip. They have the carbon the phresh filter uses.

I just tap on them and rock them some when I change pre filters. Not much work for better performance.

That’s a good point. But the water degrades and uses up the carbon steadily.
