- Does the aroma tray affect filtration?
- No. The tray holds essential oils separately from the HEPA filter, so scent is added to the outgoing air without passing through the filter media.
- What size room is it good for?
- It is built for small spaces such as a bedroom, nursery or office. For a large living area, a full-size tower with a higher clean-air delivery rate is the better fit.
- Does it have an auto mode or air quality sensor?
- No. You set the fan speed yourself; there is no sensor-driven automatic mode or air quality readout.
- How often does the filter need replacing?
- Crane recommends changing the HEPA filter periodically depending on use and air quality. Check the filter for discoloration and replace it when airflow drops.
- Can I use it without essential oils?
- Yes. The aroma tray is optional; the purifier works as a standard HEPA unit with the tray empty.
