Carbon filters...life span and refurbishing?

Filters are rated for single pass. So if you put a 400 cfm fan with a 400 cfm filter the air will basically shoot right on thru the carbon and hardly filter it. Getting a filter that is rated double the amount your fan pulls will clean the air better at a slower rate. The air has more time to get a nice cleaning as it passes thru the carbon.

With a 2 x 4 you need about 200 cfm of air moved 24/7. I would use a 200 cfm fan and a filter rated between 350 to 450 cfm. Phat has 4 x 20 350 cfm, a 6 x 16 375 cfm and a 6 x 20 450 cfm.
OK. I'll do some measuring, and go big as possible. Appreciate it.

As far as longevity goes, a lot of current filters have a removable flange that you can mount to the opposite end.
It helps extend the useful filter life by using the available carbon more effectively.

Yeah I don't know. I have a few more weeks before this flower gets emptied. I'll check to see if that's a thing. More so, I'm just really unimpressed by the performance so far. If this it, then that's trash lol. Tbh my current grow isn't that loud per se, I have some stuff coming up that's funky at 40 days from seed. It's really just privacy and security concerns.

I'm in late flower, have the AC INFINITY oversized 6inch filter. While blowing leaves outside today I could smell my exhaust. Could it be I don't have it sealed properly and untreated air is leaking by? Any help would be great. Also any links to the mountain air or Kootenay would be great. Thanks
FWIW, I've seen several say it's not a great filter.

About refillable filters, the major component and cost of a filter is the carbon. I see little savings by repacking, I see it as a marketing tactic. The only thing saved and reused is a couple flanges and the perforated metal, pennies compared to the carbon cost. The carbon is the difference between a good filter and a poor one, what's the quality of your replacement carbon? What is a good brand of replacement carbon???? Is saving a few dollars worth the work, the mess and the risk of a less effective filter?

First time running a filter. There is no way once or a twice a year is normal or ok (with me anyhow). This is my hobby, but I like to be frugal.
this is everyone's hobby. idk what to tell u. when it expires u need to change it out bud. Hobbies cost money. Refillable filters are going to cost you just as much if not more. this really isn't a discussion.

Not sure how much of the capacity you're using. Let's say your filter is 400m³/h max and you're running it at 75% of max capacity.
Do 3 runs with it and the 4th run go blow the extracted air into your room and you'll see when you come home from work, what we're talking about.

Or rather smell....
(:

I don't need to do 3 runs to know, I've not completed one and there is a problem. ?

I didn't really see this - my bad, sir...
Maybe make a dual setup then if you're not happy with performance.
So you can run it at 50% capacity or lower. Should help.

It may be refillable, but I really don't want to mess with the process. I'll be ordering a PHAT filter. It's an experience, and to be fair I can only smell it. It's not offensive yet, I was just really shocked about the time frame. But I'm literally at peak with terps and it may just have maxed out its potential. Q

The 2 filter setup however may be in the end the way. @420AD

Yeah when you're in full flower and ure pulling air too fast through your filter, it's like putting deodorant on after a week of not showering, ain't gonna do much... :bigjoint:
