Ethyl alcohol, found in vodka and other spirits, is a main ingredient in most commercial air fresheners. Cleaning your air with vodka allows you to get rid of musty odors without saturating the air (or your lungs) with added chemicals, like petroleum-derived propellants and harmful synthetic fragrances. Vodka leaves no odor as it dries, so you can spray it straight into your air as is, or add 20 to 30 drops of your favorite essential oils for a pleasant scent.
2. Cat Litter
Have a smelly closet or musty basement? Set out a tray of cat litter, specifically, Jonny Cat Litter brand, recommends Joey Green of Joey Green’s Cleaning Magic. One primary reason that brand works so well has to do with the fact that the main ingredient is Diatomaceous earth, a naturally occurring mineral that, among its many wonders, absorbs odors (it also absorbs moisture in the air and kills pests that come in contact with it). So if you can’t find any Jonny Cat Litter, buy a box of Diatomaceous earth and set a few bowls out in the corners of smelly rooms. You can find it online from garden supply stores, such as Planet Natural.
3. Coffee Grounds
Who doesn’t love the smell of coffee? According to Green, it’s another weird odor remover that helps cut the smell of winter mustiness. You can use fresh or used grounds, but if going with used, let them dry out a bit first. Place them in a bowl wherever you need an odor removed, or wrap them up in a coffee filter or old stocking and hang them in a closet or from a shelf. If you’re not a coffee drinker, you can still benefit. Some Starbucks (and many small locally owned cafes) give their used coffee grounds away for free.
4. A Palm Tree
We’re not talking about palm trees at the beach (though a beach vacation is a good way to get away from dirty indoor air). Palm trees used as houseplants are very effective air purifiers, known to remove formaldehyde, which lurks in paints, furniture finishes, and the glues used to hold pressed wood and particle board together. You’ll get similar benefits from a variety of other houseplants, but palm trees are among the easiest to care for. Look for Dwarf date, bamboo, areca, lady, or parlor palm varieties.
5. Your Skin
Thanks to all the oils in your skin, dead skin flakes act like natural air purifiers, say researchers from Denmark. According to their study, published in Environmental Science & Technology, one of the most common oils in skin, squalene, reduces levels of the indoor air pollutant ozone, a respiratory irritant that can trigger asthma attacks. After comparing levels of ozone in a day-care center’s indoor air with the amount of squalene from skin flakes in its dust, the researchers determined that dead skin flakes can reduce ozone levels anywhere from 2 to 15 percent. We’re not quite sure how to make use of this information, but it’s nice to know you’re producing your very own natural air purifier.
6. Elbow Grease
Ultimately, the best way to deal with smelly or chemical-laden indoor air is to go straight to the source. It’s easier to eliminate an odor’s cause than to try to cover it up with coffee grinds or cat litter. And indoor air pollutants that collect in dust can be trapped by a good vacuum and weekly dusting with a damp cloth. To prevent further polluting your indoor air, make your own green cleaning kit with white vinegar, lemon juice, baking soda, and borax, all of which are also natural odor removers
