If you live in a relatively new home, you probably have good seals around windows and doors. Older homes, you will notice, are draftier. While this is a wonderful thing in the Texas summer, and in our occasional winter sprinkling of snow, it also does a good job of keeping out fresh air. Without fresh air, a home can accumulate a buildup of materials from furniture, carpets, construction, pets or smoke can cause what would certainly be called smog were it outdoors. You can be proactive about improving your home’s air quality by doing these things:
- Regularly change the filters in the heating, ventilating, and air conditioning systems
- Open windows and doors whenever practical
- Use exhaust fans routinely in kitchens and bathrooms and clean or replace the filters in those fans
Be aware of moisture in your home as well. Too much moisture promotes mold and mildew growth on clothes, walls, closets and basements. Dehumidifiers reduce moisture in the air in a similar way as an air conditioner. Cool air holds less moisture than warm air, so if you need to get rid of moisture quickly, you can turn on the air conditioner or heat the house for a short time and then quickly opening doors and windows to exchange the moisture-laden air for cooler, drier air.
