Our Sample Sets come in 20ml bottles (3 or 5 scents) and are designed for trying scents before buying full-size — about 2 weeks of fragrance per bottle. Our Discovery Gift Boxes contain three 50ml bottles in a gift-ready presentation box — closer to a full-size experience, ideal for gifting or when you already know you love the brand.

A 20ml bottle lasts about 2 weeks at moderate diffuser intensity. A 50ml bottle lasts 4-6 weeks. Actual duration depends on your diffuser type, intensity setting, and daily run time.

Yes. Scentia oils are compatible with any waterless diffuser — cold-air, HVAC, ultrasonic, or reed — including diffusers from other brands. If you already own a Hotel Collection, Aroma360, AromaTech, or similar diffuser, our oils will work in it.

Because samples are opened for use, we can't accept returns on opened oils. We do offer a satisfaction guarantee — if a scent isn't what you expected, email us at cs@scentiausa.com and we'll work with you on a replacement or store credit.

Yes. The 20ml and 50ml sample bottles contain exactly the same fragrance formula as our 120ml and 500ml full-size bottles — same concentration, same ingredients, same scent profile. Sample sizes just let you try multiple scents before committing.

No. Every sample set is available as a one-time purchase at full price. Subscription is optional — if you choose to subscribe, you save 20% on recurring deliveries with a 3-cycle minimum. Cancel, pause, or swap scents anytime by email.
