Diffuser FAQ

How does cold-air diffusion work?

Your diffuser uses waterless cold-air atomization. It turns pure scent oil into an ultra-fine, dry micro-mist — with no heat and no water — so the scent stays true to the bottle and spreads evenly through your space. Because the oil is never diluted, a little goes a long way.

Is cold-air diffusion safe to use at home?

There’s no flame, no heat, and no water or steam — just a fine, dry mist of scent oil. We use premium, IFRA-compliant scent oils that are free from phthalates, parabens, and synthetic dyes. As with any home scenting, use indoors, keep the unit and oils out of reach of children and pets, and discontinue use if any irritation occurs.

How is it different from an ultrasonic diffuser?

Ultrasonic diffusers mix oil with water and release a damp mist, which dilutes the scent and adds humidity to the room. Cold-air atomization is completely waterless — it disperses the oil directly as a dry micro-mist, so the scent is stronger and longer-lasting, with no water to refill, no dampness, and no residue.

Can I control my diffuser from my phone?

Yes. Your diffuser pairs with the free Scent Master Pro app for iPhone and iPad over Bluetooth, so you can set scent intensity, run and pause timing, and daily schedules right from your phone. New to it? Our quick setup guide walks you through pairing step by step.

Can I use other brands’ scent oils?

We recommend using only Simply Modern Scents approved diffuser oils, which are formulated specifically for cold-air atomization. Thicker, diluted, or water-based oils from other brands can clog or damage the unit — and using non-approved oils will void your warranty.

Does my diffuser come with a warranty?

Yes — your diffuser is covered by a warranty against manufacturing defects. Adding water, diluting oils, modifying the unit, or using non-approved oils will void it. If anything isn’t working right, email Simplymodernscents@gmail.com with your order number and we’ll make it right.

What makes Simply Modern Scents diffusers special?

Every scent is crafted with premium, IFRA-compliant oils by American scent houses — beautiful scent, cleanly made.
