Negative: I procrastinate, and found that I wasn't able to use my room humidifier since I don't have a spare, so I've suffered for a few days, since my room is dry as the furnace runs and dries the air.
Postive: I telephoned some stores looking for a replacement filter, and decided on three stores which might have it, so I can go to them tomorrow, when I'm feeling better.
After examining the design of the humidifier, I realized that the unit can run without a filter. In fact, I don't any value for the filter at all, and could go the season without the filter, probably saving me money, and time shopping for it, as well as reducing any risk of mould accumulating on the filter.
A little procrastination saved me time, money and my health could be better.
