Not always but I'm proactive because apartment living. Best filter I've tried is actually hydrofarm probably second is phresh.
Any hint and the filter is replaced.
Eta: a year is a lie. I also think many of us growers get accustomed to the aroma and not notice the changes as non smokers/growers do
well now i think i should also change the filter as it's been over a year. i recently changed the ... crap, what is it called--the once-white fuzzy material over the filter--just a few weeks ago. i just changed it because it was dirty, not because of smell. but maybe i am used to it? although i just did go through a six-week break from smoking and would have noticed it then? okay, i'm rambling because the break is over.
