Home fragrances fall into five main categories: reed diffusers for a constant scent without electricity, ultrasonic diffusers for an instant cool mist, room and fabric sprays for quick freshness, scented candles for an evening ritual, and essential oils as refills for devices. In this guide we explain, for each category, how it works, who it is for and where its limits lie.
How does a reed diffuser work and who is it for?
A reed diffuser is the right choice if you want a room to smell good all the time, without flame or electricity. The reeds absorb the fragrance and release it evenly into the room, and it works for 4 to 12 weeks, depending on the refill and the number of reeds. You control the intensity simply: more reeds mean a stronger scent. Intense fragrance diffusers are based on a rich blend of precious essential oils and plant-based alcohol, and scent the room intensely and for a long time.
Place the diffuser in a transitional spot with gentle air movement, not in direct sunlight or on a radiator, and flip the reeds once a week. When the fragrance runs out, there is no need to throw the bottle away: use a diffuser refill. For a more decorative approach, there are also the natural diffuser with crystal stones and the potpourri diffuser. We have collected all the placement steps in our article on the correct use of diffusers. The only limitation: the effect is not instant, the scent builds up in the room gradually.
When should you choose an ultrasonic diffuser?
An ultrasonic diffuser creates a cool mist from water and 5 to 10 drops of essential oil, which scents the room immediately and humidifies the air at the same time. It is an excellent choice for the heating season, when indoor air is dry, and for anyone who likes to change scents often. An elegant option is the Flame ultrasonic diffuser in white or black.
There are two limitations: the device needs electricity and regular cleaning. You will find a detailed comparison of both approaches in our article on ultrasonic versus classic diffusers.
When is a fragrance spray the right choice?
When you want fragrance here and now: before guests arrive, after cooking, in the hallway. Just 2 to 3 sprays into the middle of the room are enough, which makes a room spray the fastest solution of all the categories. Multi-purpose fabric sprays go a step further: they are also suitable for textiles, applied from a distance of about 30 cm, though you should first test delicate fabrics on a hidden part.
The limitation: the effect is instant but short-lived, so a spray works best as a complement to a constant fragrance, not as the only solution.
What does a scented candle offer?
A scented candle is a category of its own: alongside the fragrance it brings the soft light of a flame and the ritual of lighting it, which makes it the loveliest choice for evening wind-down. Since it only burns when you light it, it makes sense to combine it with a constant fragrance: a diffuser provides the base scent of the room, the candle marks special moments. You will find the selection in the scented candles collection.
Always follow safety rules with candles: never leave them burning unattended, and keep them out of the reach of children and away from draughts.
How do you use essential oils?
If you use an ultrasonic diffuser or an air humidifier at home, choose water-soluble natural essential oils, which are 100% natural, organic and sourced from organic agriculture. 5 to 10 drops are enough: orange and cinnamon for a warm festive mood, eucalyptus for freshness, jasmine for evening relaxation. The limitation is a logical one: an essential oil cannot scent a room on its own, it needs a device to disperse it into the air.
Which home fragrance category is right for you?
| Category | How it works | Effect and duration | Who it is for |
|---|---|---|---|
| Reed diffuser | Reeds absorb the fragrance and release it gradually | Constant scent for 4 to 12 weeks | For a constant, unobtrusive scent without electricity |
| Ultrasonic diffuser | Cool mist from water and essential oil | Instant effect while the device is running; humidifies the air | For dry air and frequent scent changes |
| Fragrance spray | 2 to 3 sprays into the room or onto textiles | Instant but short-lived effect | For quick freshness as needed |
| Scented candle | The heat of the flame releases the fragrance | Smells only while it burns | For an evening ritual and atmosphere |
| Essential oil | Dispersed by an ultrasonic diffuser or humidifier | 5 to 10 drops for an instant gentle scent | For natural scents and your own combinations |
Which fragrance belongs in which room?
- Living room: warm, full fragrances: vanilla, coffee, wood. An intense fragrance diffuser or a room spray.
- Bedroom: calming notes: lavender, jasmine, powdery musk. A gentle spray on the bedding or a few drops of essential oil in a diffuser.
- Bathroom: fresh, clean notes: ocean, citrus, eucalyptus. A spray or a smaller diffuser with fewer reeds.
- Hallway: the first impression of your home: choose your signature scent and maintain it with a diffuser.
- Car: the car is part of your home too: a practical option is the scented car sachet.
A simple rule applies: the smaller the room, the lower the intensity. In the bathroom a few reeds or a single spray is enough, in the living room you can allow yourself more. A constant draught by a window literally carries the fragrance away, so do not place a diffuser there.
How do you match your home and your laundry?
The most beautiful effect comes when the fragrances align: if you wash your bedding with the SIVKA (lavender) laundry perfume, refresh the bedroom with a spray in the same scent. That way your home smells harmonious, not chaotic. Start with one room and one scent, then gradually extend the fragrance through your home.

Frequently asked questions
How long does a reed diffuser last?
A reed diffuser works for 4 to 12 weeks, depending on the refill, the number of reeds and the size of the room. When the scent weakens, flip the reeds; when the fragrance runs out, simply top up the diffuser with a refill.
Are essential oils suitable for all diffusers?
Our natural essential oils are water-soluble and intended for ultrasonic diffusers, air humidifiers and essence burners. A classic reed diffuser takes a dedicated refill, not pure essential oil.
How intense should a home fragrance be?
Less is more: the fragrance should support the room, not overpower it. With a diffuser you control the intensity with the number of reeds, with a spray with the number of sprays, and with an ultrasonic diffuser with the number of drops of essential oil.
How does an ultrasonic diffuser differ from a reed diffuser?
A reed diffuser releases fragrance gradually, without electricity, and works for 4 to 12 weeks. An ultrasonic diffuser instantly creates a cool fragrant mist from water and essential oil and humidifies the air as it works, but it needs electricity and regular cleaning.
Can I use a fabric spray on textiles?
Yes, multi-purpose fabric sprays can also be applied to textiles from a distance of about 30 cm. Test delicate fabrics first on a hidden, less visible part. For a long-lasting scent on fabrics, however, use a laundry perfume.
