The Truth About Air Fresheners (And What to Use Instead)

I’ll never forget the day I realised my beloved vanilla plug-in air freshener might be doing more harm than good. I was pregnant with my second bub, deep in a research rabbit hole about nursery safety, when I stumbled across some pretty confronting information about what we’re actually breathing in when we “freshen” our air.

Look, I get it. We all want our homes to smell nice. There’s something deeply satisfying about walking into a house that smells like fresh linen or eucalyptus rather than last night’s fish and chips. But here’s the thing — most conventional air fresheners aren’t actually cleaning our air. They’re masking odours with a cocktail of chemicals that, honestly, our families don’t need to be breathing in day after day.

Let me share what I’ve learned, without the fear-mongering, and give you some genuinely lovely alternatives that actually work.

What’s Actually in Your Air Freshener?

Here’s where it gets a bit uncomfortable. Most commercial air fresheners — whether they’re sprays, plug-ins, gels, or those little trees hanging from your rearview mirror — contain a mix of ingredients that manufacturers don’t have to fully disclose. The word “fragrance” on a label can actually represent dozens of different chemicals.

Some of the common nasties include:

• Phthalates — used to make scents last longer, these are known endocrine disruptors that can mess with our hormones
• Formaldehyde — yes, the same stuff used to preserve specimens in science class
• Volatile Organic Compounds (VOCs) — these can irritate airways and contribute to poor indoor air quality
• Synthetic musks — which can accumulate in our bodies over time

A 2007 study found that many air fresheners, even those marketed as “natural” or “green,” emitted chemicals that aren’t listed on their labels. And because our homes are more sealed up than ever (hello, energy efficiency), these chemicals just hang around in our living spaces.

I’m not sharing this to make you panic or feel guilty about every candle you’ve ever burned. I just think we deserve to know what we’re bringing into our homes so we can make informed choices.

Why This Matters for Our Families

Our little ones are more vulnerable to environmental toxins than we are. They breathe faster, their bodies are still developing, and they spend a lot of time close to the ground where chemicals settle. Kids with asthma or allergies can be particularly sensitive to synthetic fragrances.

Even for us grown-ups, regular exposure to these chemicals has been linked to headaches, respiratory irritation, and for some people, hormonal imbalances. That “fresh” scent might actually be contributing to that foggy feeling you can’t shake.

The good news? Once you stop using synthetic air fresheners, you might notice you breathe easier — literally. Many mums in our community have reported fewer headaches and better sleep after making the switch.

Natural Alternatives That Actually Work

Right, so we’ve established that the plug-ins have to go. But what do we use instead? Because let’s be honest, toddlers are smelly, bins get funky, and sometimes you just want your bathroom to smell like something other than, well, bathroom.

Here are my favourite tried-and-tested alternatives:

Essential Oil Diffusers

This is my absolute go-to. A good quality ultrasonic diffuser with pure essential oils gives you that beautiful ambient scent without the nasties. I love using eucalyptus and lemon in the living areas, and lavender in the bedrooms before sleep. I’ve linked the diffuser I use below — it’s been going strong for three years now.

DIY Room Sprays

So simple it’s almost silly. Fill a glass spray bottle with water, add a splash of witch hazel or vodka (helps the oils disperse), and 15-20 drops of your favourite essential oils. Shake and spritz. My favourite combo is orange, clove, and cinnamon for the cooler months.

Beeswax Candles

Unlike paraffin candles (which are petroleum-based and release their own set of chemicals), pure beeswax candles actually help purify the air by releasing negative ions. They have a subtle, natural honey scent that I find really grounding. This is the brand I swear by — Australian-made and absolutely gorgeous.

Simmer Pots

Old school but brilliant. Fill a small saucepan with water and add things like cinnamon sticks, citrus peels, vanilla pods, or fresh herbs. Let it simmer on low and your whole house will smell incredible. Just keep an eye on it and top up the water as needed.

Good Old Fresh Air

Sometimes the best solution is the simplest. Opening windows for even 10 minutes a day makes a huge difference to indoor air quality. I try to do a quick “air out” every morning while the kettle boils.

Tackling Odours at the Source

Here’s something worth mentioning — the best way to have a fresh-smelling home isn’t to mask odours, it’s to eliminate them in the first place. A few things that help:

• Sprinkle bicarb soda in bins, on carpets (vacuum after 15 mins), and in smelly shoes
• Keep a small bowl of bicarb in the fridge to absorb food odours
• Wash soft furnishings regularly — cushion covers, throws, curtains
• Deal with damp issues promptly (mould is a major source of bad smells and health problems)
• Take the bins out more often (groundbreaking advice, I know!)

Once you reduce the actual sources of bad smells, you’ll find you don’t need to cover them up nearly as much.

Making the Switch Without Overwhelm

If you’re looking around your house right now at a collection of plug-ins and scented candles feeling overwhelmed, take a breath. You don’t need to throw everything out tonight and start from scratch.

Start with the spaces where your family spends the most time — living areas and bedrooms. As your current products run out, simply don’t replace them, or swap in a natural alternative. Maybe invest in one good diffuser and a few quality essential oils to start.

Progress over perfection, always. Every small swap matters.

Your Home, Your Choices

At the end of the day, you know your family best. Maybe you keep one scented candle for special occasions because it brings you joy. Maybe you go full essential-oil-enthusiast like me. There’s no judgement here — just information so you can make choices that feel right for your home.

What I love most about switching to natural alternatives is that my home still smells beautiful, but I’m not worried about what we’re breathing in anymore. And honestly? The natural scents feel more grounding and less artificial once you get used to them.
