Frequently asked questions

Scent is the most overlooked layer of a home. We pour thought into furniture, lighting, and art — yet the way a room feels the moment you walk in is shaped just as much by how it smells. A scent you love turns a house into somewhere you exhale. There is a reason the finest hotels and boutiques build a signature scent into their space: smell is wired straight to the parts of the brain that hold memory and emotion, so the right scent can lift your mood, mark a moment, and linger long after you have left the room. Bringing that same intention home gives you a space that welcomes you, settles you, and feels unmistakably yours.

Most orders are delivered within 3 to 5 business days, though it can take a little longer during peak seasons and holidays. You will receive tracking details by email as soon as your order is on its way.

At this time we ship within the United States only. We hope to offer international shipping down the road, so stay tuned.

We accept returns on unopened, unused items in their original condition within 10 days of delivery.

Our electric diffusers are waterless. They use cold-air diffusion to turn pure scent oil into an ultra-fine, dry mist — no water, no heat, and no flame. That keeps the scent true and lets it carry evenly through a room.

There is no flame, no heat, and no water or steam — just a fine, dry mist of pure scent oil. Our oils are premium and IFRA-compliant, 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.

Ultrasonic diffusers mix oil with water and release a damp mist, which dilutes the scent and adds humidity to the room. Cold-air diffusion 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.

Place your scent oil into the base (or fill the well, depending on your model), reconnect the cap, and power on. Each diffuser includes a quick-start guide. Start on a lower setting and adjust up until the scent level feels right for your space.

It depends on your intensity setting and run schedule. Running in short intervals (a cycle of seconds on, then off) makes a bottle last far longer than running continuously. Most customers on a moderate, intermittent schedule get weeks of scent from a single refill.

We offer everything from compact units for a single room up to whole-home systems. Each product page lists the recommended coverage for that model — match it to the square footage you want to scent. Not sure? Reach out with your room or home size and we will recommend the right fit.

Most models let you set intensity and a timed on/off schedule (with quiet hours on larger units), using the controls on the device or the companion app where supported. Lower intensity plus intermittent cycles gives a balanced scent and a longer-lasting bottle.

To keep output strong, run a cleaning cycle periodically with an alcohol-based diffuser cleaner, or as directed in your manual. Switching scents? A quick cleaning cycle clears the line so the new scent comes through clean. Wipe the exterior with a dry, soft cloth.

First, check the oil level and make sure the bottle and cap are seated snugly. If it has been a while since the last cleaning, run a cleaning cycle — residue can build up and reduce output. Confirm your intensity setting and that nothing is blocking the mist outlet. Still not right? Contact us and we will help you troubleshoot.

Yes. Our larger systems, including the SMS1000, can connect to your HVAC to scent an entire home or commercial space evenly. If you are interested in a whole-home or HVAC-integrated setup, reach out and we will walk you through the options and installation.

We recommend using only Simply Modern Scents approved diffuser oils, which are formulated for cold-air diffusion. Thicker, diluted, or water-based oils from other brands can clog or damage the unit — and using non-approved oils will void your 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 is not working right, email Simplymodernscents@gmail.com with your order number and we will make it right.
