Advanced Aromatherapy Technology

As a waterless aroma diffuser, QW701 cold-mist diffuser applies cold-nebulizing principle with zero water required, different from traditional water-filled ultrasonic diffusers. Traditional ultrasonic units dilute essential oils and risk mold growth from residual water. This waterless essential oil diffuser atomizes pure oil into fine dry mist, preserving original aroma without adding extra humidity to your surroundings.

The built-in vibration sensor is the highlight of this car waterless diffuser: it auto-powers off after 3 minutes without vehicle vibration when parking; resumes scent mist automatically once vibration is detected upon car ignition — no manual operation needed.

Compact dimension Φ70mm × H140mm, net weight 400g, fits perfectly inside car cup holder. Placed on desk at home, it becomes an elegant home waterless aroma diffuser.

FAQ

Q1. What is the difference between this waterless aroma diffuser and ultrasonic diffusers?
A: This waterless essential oil diffuser works with zero water, atomizing pure essential oil directly without raising air humidity or mold risk. Traditional ultrasonic diffusers require water which dilutes aroma and may breed mold. This unit is for pure essential oils only — DO NOT add water.

Q2. How does the car vibration-sensor mode work?
A: Built-in vibration sensor works on a 3-minute detection cycle. It auto-shuts down when no vibration is sensed for 3 minutes after parking; resumes mist automatically when car vibration is detected upon ignition — no manual button-press needed.

Q3. How long is the battery runtime? Can it work while charging?
A: Working runtime approx. 6 hours on full charge. Supports operation while Type-C charging.

Q4. Can I use perfume or diluted oils?
A: Only use 100% pure plant essential oils. Avoid perfume, fragrance oil or diluted oil — these may clog the atomizing nozzle.

Q5. Can this diffuser be used both for car and home?
A: Yes! QW701 is dual-purpose: works as car waterless diffuser with vibration-sensor mode for vehicle, and as home waterless aroma diffuser manually switching low/high mist modes for indoor tabletop use.
