I don't know if this is applicable for what you are doing, but how about getting standard insurance coverage for more than one neb cup per 6 months -- do they seriously think everyone is going to wash, rinse and dry only one cup twice a day for 6 months then wait to get another cup to be paid for by insurance? I pay out of pocket to buy about 6 at a time so we can wash them all and be done for a couple of days.
