Do you use dust filters and wash them as needed? Seeing mine needing a cleaning so often makes me wonder how much longer those help the filters live.
I have a 4” and 6” filter over a year old still running strong, vivosun.
My 4” one still works with no dust filter and used with tap water humidifier and still working strong for drying herb. No filter because it blows air sitting outside of tent.
Makes me wonder why people have less life with theirs. It wasnt used as intensively like it is now with plenty of odor to scrub and will for as long as it lasts.
Ill buy the same ones because they worked so well. Not that costly for long as they last. edit Im high as heck I just saw the pollen part. Not so sure about that.
