I give my a/c systems a blast of Dettol All-in-One Disinfectant spray now and again. Labelled as killing a fair old range of bacteria and viruses. Seems to keep the systems clean and fresh at a modest cost. Certainly cured the musty smell and headaches on a recently acquired CLK.
Don't forget that cars with 581 auto a/c will have a second filter mounted above the passenger footwell. Its primarily for use when the under bonnet pollution sensor detects sufficient pollution in the incoming air to close the external air intake, switch to recirc and pass the air through this quite thick carbon filter. Willing to bet this filter is seldom checked or changed.
