That's good news for anyone who has problems with dust, mold, pollen and other allergens. Most of us spend almost of one-third of a lifetime in the bedroom, more than any other room in the house. If you suffer from allergies, remove any bedroom clutter which could trap dust and other irritants. Limit the number of knicknacks and other objects you have in your home, as they tend to collect dust. If you have objects you like to display, such as trophies, consider placing them in a glass case.
Wood floors catch less dust and dirt than carpets.
If you do have carpets, choose ones with shorter pile. If you are selecting a heating system, avoid forced hot air which tends to blow dust and other allergens into the air. Forced hot water systems provide cleaner heat.
