Does the Portico need water?

No. It is a waterless diffuser; add only compatible fragrance oil to the 400 mL reservoir and never add water.

How long does a full reservoir last?

It depends on the setting. The lowest mode runs 15 seconds on and 165 off, so a full 400 mL reservoir lasts far longer than on the 120-on/60-off mode.

Can I control it from my phone?

Yes. It pairs with the Tuya app over Bluetooth or Wi-Fi; hold SET for 5 seconds to enter pairing mode. On-device buttons work too.

Can it be wall-mounted?

Yes. It is designed for tabletop or wall mounting, but it needs a 12V outlet within reach of the adapter.

Is fragrance oil included?

No. Oil is sold separately, so budget for compatible waterless fragrance oil on top of the diffuser.

Is $89.99 a good price?

It is the only new price listed, $89.99 at Aroma Paradise as of November 7, 2026, so there is no competing store price to compare it with.

Our take on the Portico Waterless Scent Diffuser

The Portico is a waterless cold-air scent diffuser that runs on pure fragrance oil from a 400 mL reservoir, with no water tank or dilution. It offers three intermittent scent settings, 1/2/3/8-hour timers, a five-stage oil-level display, and Tuya app control over Bluetooth or Wi-Fi. It sits on a tabletop or mounts on a wall and measures 202 × 158 × 75 mm. The best new price is $89.99 at Aroma Paradise as of November 7, 2026, and only one store lists it new, so there is little price history to compare against.
