51. Let your bed air out before you make it each day. This will allow mite-friendly moisture to evaporate. Airing out your pillows and vacuuming the mattress will help control mites too.
52. Screen out pollen. If you have a window air conditioner, use the fan setting, and change or wash the filter often. Keep windows closed.
53. Stop using moth balls, period. They contain possible carcinogens. Store clean silks and woolens in zip-up bags. Buy cedar chips from a pet store, and make your own sachets by wrapping them in cheesecloth; toss or refill when they lose their scent.
54. Avoid placing office equipment in the bedroom; copiers and printers can generate lung irritants.
