Im sure there are factors that reduce the life of any carbon filter , like if you run humidifiers and your extraction fan is running 24/7 then id imagin the carbon would eventually get water logged and im sure if the pre filter sleeve isnt used it probably reduces lifespan aswell .
So it might be how we use the carbon filter that determines lifespan .
Just a thought

Generally, the bigger the filter the better, but there are some factors that affect longevity and efficacy. Surface area of the carbon matters and it’ll differ due to particle size/shape (grades of carbon will have a label distinction assigned to them). Carbon bed thickness matters too, as does fan speed, because it relates to the contact time between the porous carbon and your stinky particulate you need to filter. Recirculating vs exhausting matters too, in terms of the filter size needed and it’s longevity. Make sure you pair up the filter CFM rate to the fan’s CFM output. Recirculating generally allows you to get by with a smaller filter setup because there is more contact time, where purely exhausting requires stronger filtration to hide your kryptonite.
AC Infinity uses great carbon for their filters, and they feature a refillable design, but the thickness of the bed and amount of actual carbon in their filters is very small compared to competition, so they don’t last long. Phat filters feature a 2” thick carbon bed, and they contain a lot of carbon. I also really like Kootenay filters, specifically the “standard line” not the “green line”.
This is the one I have in my flower tent. It has 50 pounds of carbon in it.

Not if you have constant negative air pressure

yes kootenay did make good filters but i think they went bankrupt and were bought i phoned the guys in bc and the old number is no longer in service it goes to some place else. im looking for something of this quality. i currently have this kind im looking to buy another for when this one dies. hydro builder was great used to order lots of shit from them but they no longer ship to canada without using a third party shipping service

fall all intensive purposes lets assume the conditions are ideal for apples to apples comparisons between brands.

the question is not about tents, im looking to compare quality of carbon, depths of carbon bed and weight of carbon between filter brands. do you know anyone that has the specs for mountain air or phresh? kootenay i think kicked the bucket or at least you can no longer reach anybody.

yea the weight is very useful i emailed phresh looking for specs and mountain air no response from either. lol
37.5 lbs for this one, 19.8lbs for phresh.

I went all superpower-ADHD and made a chart of like 10+ filters a while back from researching. I compared the internal weight of the carbon, thickness of carbon bed, overall size and CFM flow rates, and prices, to eventually find the one I needed. I forgot that you’re up north, and that shipping can get a bit complicated.
Do your due diligence, and just start looking up brands and comparing what’s available to you in your area. I’ve seen your journal, you’re pretty thorough, got all the T’s crossed and I’s dotted.
