How to Naturally Purify Indoor Air (Without Chemicals)

Did you know: Indoor air pollutants are often 2-5 times higher than outdoor levels, with some cases exceeding 100 times that of outdoor levels!

Indoor air is often more polluted due to lack of air flow coursing through the building.

In today’s chemical laden world, we’re exposed to toxins all the time, making it almost impossible to avoid them completely (you’d have to live in a sterilised ball for the rest of your life). Knowing this, I do my best to reduce the amount of toxins and pollutants I come into contact with on a daily basis.

According to Wellness Mama:

A whopping 30-50% of all buildings are damp enough to encourage mould and bacteria growth according to EPA reports on air quality and asthma. These pathogens then increase the risk of certain health conditions, like asthma and infectious diseases.

Some common sources of air pollution inside include:

Dust
Outdoor air pollution leaking in
VOCs off-gassing from paint, furniture, flooring, etc.
Pet dander
Conventional cleaners, air fresheners, and other fragrances
Gas stoves and other appliances (especially older ones)
Dampness and mould growth
Carpet, drapes, and other furnishings that collect dust and dirt

Using an indoor air filter can be very useful in filtering out toxins hiding in the air, but there are other natural methods that work just as well in minimising exposure to toxic airborne chemicals:

Indoor Plants

Houseplants make great air purifiers as they’re really effective at filtering out the air in your home while providing fresh oxygen for you to breathe. They also brighten up the place and bring a little bit of nature into the home.

Plants not only help to purify air, but they brighten up the home, too!

According to Treehugger:

Spider plants are effective at reducing benzene, formaldehyde, carbon monoxide and nitrogen dioxide.

Some other examples include:

  • Barberton Daisy – Effective for filtering out toxins like formaldehyde, trichloroethylene, and benzene.
  • English Ivy – Effective at reducing airborne faecal particles (perfect to have in your bathroom or ensuite) and mould.
  • Snake plant (a.k.a Mother-in-Law’s Tongue) – Releases oxygen at night, and helps to filter out formaldehyde, xylene, benzene, toluene, and trichloroethylene.
  • Chrysanthemum – Effective for filtering out toxins like ammonia and benzene, often found in plastics, detergents, and glue.
  • Aloe Vera Place in a sunny location, and this healing plant will help filter toxins such as formaldehyde and benzene, which can be found in varnishes, floor finishes, and detergents.
  • Broad Lady Palm – Helpful for reducing levels of ammonia, a chemical commonly found in a range of cleaning products.
  • Red-Edged Dracaena (a.k.a Dragon Tree) – Effective for filtering out pollutants like Trichloroethylene and xylene.
  • Bamboo Palm – Famed for its effectiveness in removing formaldehyde from the air.
  • Kimberly Queen Fern – One of the most effective indoor air purifiers.
  • Pineapple Plant – Known for its ability to purify the air and remove harmful toxins.
  • Chinese Evergreen – Effective at removing pollutants like formaldehyde and benzene, commonly found in detergents and cosmetics.

Salt Lamps

Anytime I think of salt, the image of Sid from the movie Ice Age pops into mind, with his famous quote, “salty!”

Fun fact: Salt lamps help to purify the air inside your home. Salt lamps are made from Himalayan salt crystals and release negative ions into the air, which bind with toxins, removing them from the air.

They’re also a beautiful source of light, giving off a pinky-orangey glow. In fact, the natural orange glow doesn’t disrupt sleep hormones like fluorescent or blue lights do. When lit, the salt crystal naturally filters the air of allergens like pet dander, pollen, smoke, and other air pollutants. It can also dilute odours, making it easier to breathe.

The lamp can be kept alight for as long as you like. I keep mine lit 24/7 to maintain the purifying effect.

Beeswax Candles

Paraffin candles are derived from petroleum (oil) and can release chemicals like soot, toluene, benzene and other chemicals into the air when lit. These types of candles should be avoided as they do more harm than good to the quality of the air inside your home.

Pure beeswax candles on the other hand, burn with nearly no scent or smoke and actually clean the air by releasing negative ions, just like salt lamps.

I love making my own beeswax candles, and place them all around the home to help purify each room.

People with asthma or allergies will find beeswax candles especially helpful as they’re very effective at removing common allergens like dander and dust from the air. Furthermore, candles made from beeswax last longer because they burn at a much slower rate.

Here’s how you can make your own!

Diffusing Essential Oils

Essentials oils like cinnamon, oregano, pine needle, rosemary, lavender, thyme, grapefruit, lemon, clove, eucalypt and tea tree have the ability to kill bacteria, viruses, fungi and mould.

According to India Today;

Studies from Webster State University have shown that Thieves oil, which is an antiseptic blend of pure essential oils like pine needle, cinnamon, thyme, eucalyptus, lemon and grapefruit, has a 99.96% kill rate against airborne bacteria. This mixture of essential oils helps keep the home free of germs and purifies the air.

I make my own essential oil blends to help with an array of ailments; such as helping to unblock congestion and soothe flu-like symptoms

Also, there’s the added bonus that your house is left smelling absolutely incredible!

Activated Charcoal (Particularly Bamboo Charcoal)

Activated charcoal makes another fantastic air cleanser. I’ve mentioned before how charcoal makes an excellent teeth whitener, and what’s even more amazing is it can effectively remove toxins in the air. The porous structure of activated charcoal allows it to trap pollutants, odours, bacteria, allergens and volatile organic compounds (VOC’s) in the air. It also absorbs moisture, preventing mildew and mould.

Things like paint, carpeting, furniture, air fresheners, chemical cleaners, rubber, and plastics can emit harmful toxins such as chloroform gases, formaldehyde, benzene, and ammonia (to name but a few). By placing some activated bamboo charcoal in burlap bags or cheesecloth around the home, the charcoal will help to freshen air, cleansing and absorbing toxins and pollutants hidden with it.

I love activated charcoal, and have many different uses for it, such as keeping my teeth clean and using it in skincare.

Placing the bags in sunlight once a month may help to rejuvenate the charcoal, allowing them to be reused again and again. These bags can last up to 2 years, where after that you can simply pour the charcoal into the soil around plants to help retain moisture and fertilise them.

Clean with Non-Toxic Chemicals

Most store-bought household cleaners contain toxic chemicals that can irritate the eyes, nose, throat and lungs. If you choose to use these, make sure to open the windows while cleaning. BUT, if you’re looking to switch to a more natural, healthier alternative, consider making your own household cleaners using ingredients like vinegar, baking soda, citrus or essential oils. Here are a few natural cleaning recipes I use.

As always, this is not personal medical advice and we recommend that you talk with your doctor before trying or using any new products. It’s important to check with a doctor before taking this or any new product, especially if taking any other medicine or supplement or if pregnant or nursing. Be sure to check ingredients to make sure there is no risk of an allergic reaction.
