Reusable Planet Blog: Super Easy DIY Chemical Free Air Freshener

Author: Rachel  Date Posted:3 June 2023 

Commercial air fresheners contain around 25 hazardous ingredients, making them toxic to humans, animals and the planet. Avoid these nasty chemicals and make your own toxic-free air freshener and room deodoriser with these super simple recipes.



It seems absurdly contrary, but air fresheners are toxic and can actually generate or further aggravate an air quality problem!

Fewer than 10% of ingredients in air fresheners are typically disclosed by manufacturers to consumers, and it’s completely legal under proprietary protection. (That’s corporate speak for secret recipe…)

Yes, your fresh-air-in-a-can emits over 100 different chemicals into the air. Approximately one quarter of them are classified as potentially hazardous pollutants.

Common air freshener chemicals such as acetaldehyde and synthetic phthalates have been associated with adverse respiratory, reproductive, immune, and endocrine system functions, and with cancer.

That’s not good for you, your family, your furry friends or the planet!

But don't worry! We're here to help you ditch the toxic chemicals and make your own air freshener without the nasties! It’s easy… your family, pets and the planet will thank you!

So here it is…



Image description: woman standing in a kitchen holding a dark glass spray bottle and small bottle of lavender oil
1/2 cup purified (best) or filtered water
1 -2 tablespoons of rectified spirit (high proof alcohol)
~ 30 drops essential oil
Fine-mist spray bottle (aluminium or dark glass is best)



  1. First add alcohol to the spray bottle.
  2. Add your essential oil/s of choice. Lavender is popular as it has calming properties and is pet safe. I also like an orange and cinnamon blend.
  3. Swirl the bottle to combine your essential oil/s with the alcohol.
  4. Top up with the water and shake before each use.
  5. Spray into the air several times. The alcohol will help disperse the oils.
  6. Never spray essential oils directly on fabrics.



  • For the water component, you can also use cooled boiled water, but the better the quality of water, the longer your air freshener will last.
  • The type of essential oil you use will also play a role in how long your air freshener will last.
  • Using a dark or frosted glass bottle will help keep your air freshener fresher for longer.
  • Some recipes use witch hazel or proof alcohol like vodka instead of rectified spirit. You can try this, however it may also affect the longevity of your air freshener and may also influence the aroma.
  • Rectified spirit is purified 95% proof and has no odour. I use Polmos Spirytus Rektyfikowany which is available at independent retailers. Keep well out of reach of kids (and some adults)!
  • Important! Research your essential oil/s of choice before using in your recipe to check for contraindications and to make sure it’s fit for purpose (e.g. pet safe, safe for pregnant women, etc).




If you’re not too keen on the spray method but still want a DIY solution, or additionally want a room deodoriser option for smaller spaces or rooms, this is for you!  


½ Cup bicarb soda (baking soda)
~ 10 - 15 drops of your favourite essential oil / blend.
Dried herbs or flowers (optional)



  • Add the bicarb and essential oil to a glass jar and pop on the lid. Give it a good shake to mix the essential oil and bicarb. Find a small decorative glass jar (a repurposed candle jar is a good option) and gently pour in the bicarb mixture. Decorate the top with dried herbs or flowers. Voila!
  • Top up with your scent of choice every few days, and refresh the whole jar once per month.
  • This is perfect for toilets, bathrooms and thoroughfares.



  • Bicarbonate soda is a natural neutraliser of odours. It absorbs odourous molecules and converts them into innocuous gases and salts.
  • Bicarb is also great for neutralising odours in the fridge, car, carpets, dishwasher, wheelie bins and more!
