Clean ingredients

Scentra™ will only ever improve the health benefits of your air. Our formulas are free from harmful additives like phthalates, parabens, eugenol, and formaldehyde. Scentra scents are also Prop 65 and Leaping Bunny certified.

Duration

Each Scentra cartridge lasts 20-30 days with purifier set to AUTO, depending on room and purifier size. Scentra works best in rooms up to 400 sq. ft.

Scentra is a research-backed fragrance technology engineered to improve your wellbeing. Grounded in neuroscience, our advanced, mood-shifting formulas combine with air purification to rethink what air can do for you.

The Scentra collection is the result of decades of research by the Health & Wellbeing and Sensory Centre of Excellence, based in Ashford UK, into how scent affects the way we feel. Using advanced brain mapping, real-time testing, and mood-matching visuals, each scent has been carefully designed to evoke a specific emotional response.

FAQs

Which purifiers is Scentra compatible with?

Scentra is compatible with all Alen air purifiers!

How long does a scent last?

Scentra scents typically last 20-30 days with purifier set to AUTO, depending on room size and purifier size.

How do I control scent intensity?

Open the Scentra dispenser to increase intensity, and close for less intensity. Always adjust intensity with the dispenser; do not lower purifier fan speed to adjust intensity as that may compromise purification.

Do I need a diffuser?

Yes! All scents require a Scentra diffuser to function. The diffuser is included in the Starter Kit.
