9 Nontoxic Essential Oil Diffusers (2024 Review)
The Good Trade editors endorse products we’ve personally researched, tested, and genuinely love. Learn more about our methodology and business model here.
Our team has researched and tested dozens of essential oil diffusers for safe, high quality, and affordable options — these are our top nine picks.
Essential oils have been used for centuries, aiding with sleep, relaxation, and overall healing. We love using them often, too (see our top essential oil picks for a good night’s sleep). It only takes a few deep breaths to understand how soothing these aromas can be!
We especially love diffused oils for homes that need alternatives to candles — whether you’re prioritizing for pet and child safety, have sensitivities to certain ingredients, or just want a home fragrance you can set and forget without worry.
Why look for non-toxic essential oil diffusers?
Nontoxic essential oil diffusers are a must if you’re looking to maintain a healthy and clean home. BPA-free and ceramic diffusers are a great option to help eliminate the potential of harmful chemicals being released into the air when the diffuser is heated. Another way to prevent this is by going for a non-heated or non-electronic diffuser (we’ve listed some options below!).
Diffusers are also a safe and nontoxic alternative to candles for scenting your home, as they use water and essential oils (which are safe when used correctly), rather than synthetic fragrances which are found in many conventional candles and can pollute our homes. As always, be sure to use care when introducing essential oils in your home, being especially mindful of how, when, and where they are used around children and pets.
These fragrance diffusers and nebulizers maximize their reach and fill our homes, offices, and home offices with natural and therapeutic scents. Plus, the essential oils we’ve paired them with use natural ingredients, and are responsibly sourced so you can breathe easy!
Our criteria:
- NONTOXIC MATERIALS | We’ve compiled the best essential oil diffusers made with nontoxic materials that are BPA-free and safe for the home.
- DESIGN AND QUALITY | We’ve selected high quality essential oil diffusers that are impeccably designed, will look beautiful (or discreet!) in your space, and that are made to last.
- AFFORDABILITY | We’ve made sure to include affordable essential oil diffuser options for both small and large spaces, so we can scent our homes while staying cost-effective.
If essential oils aren’t for you, our guides on nontoxic candles and eco-friendly humidifiers will keep your home smelling fresh and your air quality on point. And for keeping your home in tip top shape, these eco-friendly cleaning supplies will make cleaning easier and safer for your health and your space!
