My air purifier does its job well. But for the last half year, it started to blow air that smell unpleasant. I replaced a set of new filter but the smell persist.
I found out the smell comes from its catalytic filter. According Dyson website, catalytic filter doesn’t need to be changed. But the smell gives me headache. I am not sure I should wash it.
I wonder if I can run the machine without the catalytic filter.
Thank you
