What is a better alternative to candles for making your home smell nice? A waterless diffuser is the closest match to what people want from a candle, without the flame. It turns fragrance oil into a fine, dry mist with no water or heat, fills the whole room rather than the space around the jar, and runs on a schedule, so your home smells nice even when you haven’t lit anything. Ascent Collection’s Scent Aura covers up to 300 m³. Reed diffusers, wax melts, room sprays and simmer pots also work, but each covers a smaller area or a shorter time.
Why look for a candle alternative?
A candle only scents the room while it’s burning, and someone has to be there to watch it. The scent stays fairly close to the jar, and it fades soon after you blow it out. Candles can also leave soot on walls and ceilings over time. If you want a home that smells nice when you walk in, not only while a wick is lit, you need something that keeps going without you.
How do you make your house smell good without candles?
To make your house smell good without candles, clean first, then use a waterless diffuser in the main living area and a plug-in diffuser in bedrooms and bathrooms. Set them on a schedule so the scent is there when you walk in. Fragrance sits on top of whatever is already in the air, so open the windows, wash soft furnishings and empty the bins before you add any scent.

Why a waterless diffuser is the closest thing to a candle, without the flame
A waterless (cold-air) diffuser releases pure fragrance oil as a fine, dry mist. There’s no water to dilute the scent and no heat to change it, so the fragrance smells the way it does in the bottle and reaches the whole room. It leaves no residue on furniture. You set the intensity and the times, and it runs on its own.
For a living area or open-plan home, the Scent Aura covers up to 300 m³ and holds up to five on and off times a day. For a bedroom or bathroom, the Scent Plug covers up to 70 m³, and a 20 mL bottle lasts around a month with daily use. For a large open-plan home, the Scent Mist covers up to 600 m³.

Which fragrance should you start with?
If you’re used to a favourite candle, start with the same scent family. Warm candles such as vanilla, amber or sandalwood point to a warmer oil. Fresh linen or citrus candles point to a fresh, clean oil. Not sure? Our sample packs let you try several oils before you choose a full bottle.

Frequently asked questions
Is a diffuser safer than a candle?
A waterless diffuser has no flame and no heat, so there’s nothing to leave burning. Ascent Collection’s cold-air diffusers are safe for use around children and pets: use them in a ventilated room, keep an eye on pets, and check with your vet if you’re unsure.
How long does the scent last compared with a candle?
A candle scents the room while it burns. A waterless diffuser runs on the schedule you set, and a 50 mL bottle of oil typically lasts about 30 days at six to eight hours a day.
Can I use my favourite candle scent in a diffuser?
You can’t use candle wax, but you can choose a fragrance oil in the same family. Start with a sample pack and compare.
Do I need a different diffuser for each room?
For most homes, one waterless diffuser in the main living area does the most work. Add a small plug-in diffuser for a bedroom or bathroom if you want scent there too.
