XEITIN Waterless HVAC Diffuser Coverage 5000 Sq.Ft, Whole House Lasting Scent Cold Air Diffuser for Large Home, Hotel, Office, 200ml Aroma Diffuser Machine with Bluetooth App Control, No Humidity

About This

• HVAC Scent Diffuser with Included Accessories: Connect this HVAC diffuser to your AC vent or HVAC setup with the included 3.9 ft tube, 0.12 in inner diameter tubing, and connector accessories. It helps solve uneven fragrance distribution in larger homes by carrying scent through your air system, so living rooms, hallways, entryways, and open spaces can smell more consistent.
• Waterless Oil Diffuser with 6.8 fl oz Bottle Capacity: The 6.8 fl oz / 200ml bottle capacity and adjustable spray schedule help reduce frequent refills and daily maintenance. This waterless oil diffuser solves the hassle of adding water or replacing small air fresheners often, helping you maintain a long-lasting home scent routine for up to 90–120 days depending on settings and use.
• Bluetooth App Scheduling for Waterless Diffusers for Home: Set working days, start/end times, spray duration, and pause intervals from the app to control when and how strongly the diffuser runs. This helps solve over-scenting, weak scent, wrong-time operation, and unnecessary oil use for after cooking, pet odor control, evening home scenting, or whole-house diffuser use. Bluetooth control only; Wi-Fi remote control is not supported.

• Why is the diffuser on but not spraying, or why is there no scent?
• This diffuser only works when the app schedule is set correctly and the current time is included in the selected Mode. Power / Running Status must also be on. Eg, if it is Monday 5 PM but the Mode only runs until 4 PM, it may stay on but not spray.
• Why was the scent strong at first, then became weak, or why is it noisy but not diffusing well?
• This is usually caused by oil residue buildup in the nozzle, filter, or bottle parts. Oil thickness and concentration can also affect performance. For example, after a few weeks, the diffuser may still run but smell much weaker.
• Scent strength is adjusted in Modes by changing Spray Duration and Pause Interval. Longer spray and shorter pause make the scent stronger. Low / Medium / High on the home page usually show oil level, not scent strength.
• Use pure essential oils or diffuser-compatible fragrance oils only. Do not add water, and avoid very thick oils or carrier oils. The light colors show oil level: red = low, yellow = medium, green = high.
• What should I do if Bluetooth won’t connect, or if parts are missing or damaged?
• Please check that the oil bottle is installed correctly, the app is set to ON, and the current time is within the scheduled working period.
