AsterOutdoor 500ml Aromatherapy Diffuser Set vs Candlelight Flame Ultrasonic Diffuser

Buy the AsterOutdoor set if you want one diffuser to scent a large room and you also need the oils to start. Buy the Aroma Paradise candlelight diffuser if you want a small, quiet unit for a nightstand or desk and care more about the flame glow than run time. The AsterOutdoor holds far more water and includes six oils, but its plastic body, lack of a written warranty and thin review base (4.7 from 10 ratings) make it the riskier long-term buy. The Aroma Paradise is smaller and runs only about 6 hours, yet its 4.8 from 285 ratings and BPA-free build give it the stronger owner track record.

  • Choose the AsterOutdoor 500ml set if you want to scent a bedroom or living room for most of a day and want the six starter oils included.
  • Choose the Aroma Paradise candlelight diffuser if you want a compact, near-silent unit with a realistic flame glow for a nightstand, desk or meditation corner.

Questions and answers

Which is better for a large living room?
The AsterOutdoor. Its 500ml tank covers a large room for 12-16 hours on low mist. The Aroma Paradise holds 120ml and runs about 6 hours, so it suits a nightstand or desk instead.
Which one is quieter at night?
The Aroma Paradise is rated under 30 dB, which is close to silent. The AsterOutdoor is also described as quiet ultrasonic, but it does not publish a decibel figure.
Do I need to buy oils separately?
Only with the Aroma Paradise. The AsterOutdoor set ships with six therapeutic oils. The Aroma Paradise includes the diffuser, power adapter and manual, so add your own oil.
Which lasts longer?
Neither lists a written warranty. The Aroma Paradise has a much larger owner base (285 ratings at 4.8) and a BPA-free build, which is the better sign for daily use. The AsterOutdoor's 10 ratings give little long-term evidence.
Is the candlelight diffuser safe to leave on overnight?
Yes. It uses LED light with no open flame or heat, and it shuts off automatically when the water runs low. The AsterOutdoor has the same auto shut-off feature.
Is the AsterOutdoor worth stepping up to over the compact one?
Step up only if you need long run time and a large room covered. If you want ambience and a small footprint, the Aroma Paradise does that better and has the stronger review record.
