As discussed in Indoor Air Quality in the Winter, now is the time of year to be especially vigilant about the fumes and other pollutants we allow to permeate our indoor air.

Due to homes sealed against cold temperatures combined with the increased amount of time our families spend indoors, indoor air pollution is of particular concern during these winter months.

One product asthma and allergy sufferers should avoid is air fresheners. Dr. James T. Li, Mayo Clinic asthma and allergy specialist, has this to say about air fresheners:

"Occasional exposure to air fresheners isn't likely to cause problems, as long as the products are used as directed. However, the chemicals in air fresheners may irritate your eyes, skin and throat. In addition, long-term use of air fresheners may contribute to indoor pollution — which can sometimes trigger asthma and other lung problems."

Instead of chemical-laced commercial air fresheners, try these methods of keeping your home fresh:

• Grind lemon peels in your garbage disposal to freshen it up.
• Sprinkle baking soda on carpets and in garbage cans for natural odor absorption.
• To deal with pet odors without chemicals, try the Gonzo Pet Odor Eliminator or the Naturally Fresh Pet Crystal.
• Odors in musty areas are absorbed safely and naturally with the Gonzo Odor Eliminator for Basements and Garages.
• For trouble spots like bathrooms or near litter boxes, try AllerAir's Tub O' Carbon Odor Buster, which uses coal to safely absorb odors.
• Use EcoDiscoveries AirZyme Air and Fabric Deodorizer to tackle odor issues in fabrics, upholstery, carpets, and other surfaces without harmful fragrances or other chemicals.
