Re: Doubling up on ResMed AS10/S9 filters good or bad idea?

Resmed machines weren't designed to have a double filter. Get the hypo-allergenic filter or at least a Resmed BRAND filter and not the knockoffs. If you have allergy problems and that doesn't fix it, you need a room air cleaner (recommend Honeywell) and keep your door closed.
