Upgrade Your Furnace Filter
Your home's forced-air heating or cooling system helps to control dust by filtering the air. A standard cheap fiberglass filter protects your furnace from large dust particles and provides maximum airflow, but it does little to reduce household dust. More expensive pleated filters usually provide a good balance between cost and filtration efficiency. These filters trap 80 to 95 percent of particles 5 microns and larger. Here are the best furnace filters to buy.
But if you have family members with allergies, consider spending more on high-efficiency filters, which capture 99 percent of airborne particles as small as 0.3 microns (bacteria and viruses, fumes and pollen). Be aware that you'll have to run your furnace fan full time to get the maximum benefit from a high-efficiency filter, and you'll have to change the filter frequently to prevent damage to your furnace from the reduced airflow.
If you go the high-efficiency route, install a filter monitor such as FilterScan, which automatically alerts you when your furnace filter needs changing, or the GeneralAire G99 Filter Gage, which requires you to manually check it.
Protect Your Shower Doors From Mineral Buildup
When the beads of water left on your glass shower door dry out, they leave minerals behind that are at best unsightly, and at worst can be tough as nails to remove if you let them build up (see first tip). You can avoid beading water altogether by coating the glass with an auto-glass treatment.
Follow the instructions on the package to apply the treatment to your shower door glass. You can buy Aquapel online or at local dealers. You'll find Rain-X at any auto parts store.
Purify the Air
- Place air purifiers in your most-used rooms to help suck up dust before it settles. Choose units with True HEPA filters rather than ionic cleaners, which release ozone, a respiratory irritant.
- Add a plant to every room. Plants naturally absorb common indoor pollutants like benzene and formaldehyde. NASA studies have shown that many plants, including aloes, palms and ferns, can absorb as much as 80 percent of the formaldehyde in a room in 24 hours.
- Keep the humidity in your house between 40 and 50 percent to help lower static electricity, which can cause dust to stick to surfaces and make them harder to clean. A humidifier (cleaned regularly) and leafy indoor plants will both increase humidity levels. Just don't increase the level to more than 50 percent. This will promote the growth of mold, a far more dangerous condition than dust. You can monitor humidity levels with a cheap hydrometer from a gardening store.
- Keep your windows closed on windy days. Dust enters through doors and windows in the form of pollen, mold spores and airborne pollutants.
