Home fragrances come in a variety of forms. Candles, oils, sprays, solids. There are some cautions to be aware of when using scented products in the home.

Health risks most associated with home fragrance are allergens, respritory and mucus membrane irritants, and ingestion.

Candles often have wicks that contain lead which becomes airborne when burned. Candles made of parafin wax emit soot. Both are health hazards. Candles made of soy wax with wireless wicks are the safest choice if you use scented candles regularly. Try to use candles scented with essential oils rather than 'fragrant oil' or perfumes.

Incense is either self-igniting or requires a heat source. Be aware of ingredients before you burn incense. A commonly used product to ignite incense is called salt-peter, which is either sodium or potassium nitrate, both are toxic. Forms of incense that require a heat source are often burned on charcoal coils or rounds. Charcoal emits carbon monoxide and is dangerous to breath especially in closed spaces. Incense, regardless of how it is burned, creates smoke, and numerous particles that enter the air. These can trigger allergies, and allergic reactions. If you enjoy incense purchase or make those that do not contain salt peter. Burn incense on makko (the byproduct of a southeast Asian tree) that does not emit toxins. Try to avoid charcoal as a heat source for burning cone or powdered incense. Keep in mind that the ingredients that provide the scent are usually powdered forms of plants, pods, barks, etc, and they will along with smoke infiltrate the air with particles.

Air freshening sprays, plug in solid, fragrance oils, and candles are most popular. In terms of safety it is best to avoid sprays. They are highly concentrated, have pressurized ingredients to emit the fragrance, some of which are toxic, and they generate huge amounts of air born particles. Caution is necessary when using sprays especially in areas where food or eating utensils are present. The particles of the spray land on whatever is exposed and can easily be ingested. If used in the kitchen it is important to cover any food you may have out and to wash off tabletops and counters after using a spray air freshener in the kitchen.

A number of 'plug in' air fresheners are available in both solid and oil forms. These are plugged into outlets and the scents are warmed over time. These may be the least toxic of commercial air fresheners. They emit fewer air born particles and work in a less intense
