A scent diffuser without oils is the diffuser hardware unit sold on its own, without any fragrance oil included. It is the identical device found in Scentiment's starter kits and bundles, just purchased separately so you can pair it with fragrance oils of your own choosing. This option is ideal for buyers who already own Scentiment oils, want to add a second diffuser to another room, or prefer to select their fragrance independently.

Buying a diffuser without oils makes the most sense if you already have a Scentiment fragrance oil collection and simply need additional hardware, or if you want to choose your oils separately based on personal scent preferences. It is also a slightly lower-cost entry point compared to starter kits. If you are brand new to Scentiment and unsure of your preferred scent, a Discovery Kit or starter kit – which includes curated oils – will give you a better starting experience.

All Scentiment fragrance oils are compatible – the full hotel-inspired collection, designer-inspired scents, seasonal blends, mood collections, and HVAC-specific oils. Oils are available in 20 ml, 50 ml, 120 ml, and 500 ml sizes. Scentiment oils are formulated specifically for cold air nebulizing diffusers, ensuring optimal atomization and scent longevity in every model.

Choose your model based on room size. The Scentiment Diffuser Mini 2 LE covers up to 500 sq ft, the Scentiment Diffuser Air 2 up to 1,000 sq ft, the Scentiment Diffuser Pro 2 up to 2,000 sq ft, and the Scentiment Diffuser HVAC 2 up to 5,000 sq ft for whole-home use. The Diffuser Air 2 is the most popular single model for home use and the best all-around choice for standard living spaces. If you are unsure, go with the model one coverage tier above your actual room size for the best results.

Yes – and Scentiment's Discovery Sets are the best way to explore the fragrance range after purchasing a standalone diffuser. Discovery sets include sample sizes of the top hotel-inspired or designer-inspired fragrances so you can find your signature scent before buying full-size 50 ml or 120 ml bottles. Discovery sets are available for hotel scents, seasonal collections, and car fragrance.

Scentiment recommends cleaning your diffuser every two to four weeks – or whenever you switch to a new fragrance oil scent. Use Scentiment Diffuser Cleaner, which is formulated specifically for cold air nebulizing systems. Simply swap in the cleaner bottle and run the diffuser through a cleaning cycle to flush oil residue from the nozzle and internal components. Regular cleaning preserves scent output and extends the diffuser's useful life.

Yes, once you add your fragrance oil. Scentiment diffusers are designed for continuous or programmed daily operation. Most models feature adjustable interval and intensity settings so you can control scent output throughout the day without over-saturating the space or consuming oil faster than necessary. Running on an interval schedule – cycling on and off – is the recommended mode for everyday home use.

Yes. All Scentiment fragrance oils are 100% cruelty-free. Scentiment does not test on animals and never will. The oils are also formulated without parabens, formaldehyde, color additives, synthetic dyes, or preservatives – clean fragrance by design, across every scent in the collection.

Yes. The diffuser hardware itself uses cold air technology – no heat, no flame, no water – making it inherently safe around children, pets, plants, and furniture. When you add Scentiment fragrance oils, those are equally safe: free of parabens, formaldehyde, synthetic dyes, and preservatives, and formulated for ambient home use. For homes with cats or birds, use the diffuser in ventilated spaces and at moderate intensity settings.

Scentiment diffusers use cold air nebulization technology – not ultrasonic mist, not heat, and not aerosol – which produces a dry fragrance mist that is stronger, cleaner, and longer-lasting than competing methods. The hardware range covers every space from a single bedroom to an entire home via HVAC integration. And unlike brands that offer generic fragrance libraries, Scentiment's oils are built around recreating the exact signature scents of iconic luxury hotels – an authentic, specific experience that mass-market diffuser brands do not offer.
