Whynter NEX Inverter 13,000 BTU Dual Hose Smart Portable Air Conditioner, Dehumidifier & Fan | ARC-1280WX
Smart Inverter Cooling with Maximum Efficiency & Control
The Whynter ARC-1280WX is a 13,000 BTU portable air conditioner built to cool larger living spaces, open-plan rooms, and home offices up to 500 square feet. The dual-hose system draws in fresh outdoor air to cool your space, then exhausts warm air outside, delivering faster, more efficient cooling than single-hose models. Powered by advanced NEX Inverter technology, it automatically adjusts its output to maintain your ideal temperature, using less energy and running noticeably quieter than conventional portable air conditioners. Built-in WiFi lets you control the temperature from your phone via the NetHome Plus app, or hands-free with Amazon Alexa, Google Home, or Apple Siri.
With 5-speed fan control, you can dial in airflow from a gentle background breeze to full-power cooling. At as low as 50 dBA, it runs quietly enough for bedrooms and home offices without disrupting sleep or focus. The built-in dehumidifier pulls excess moisture from the air, so your room stays cool and comfortable even on the most humid summer days. An activated carbon filter tackles odors and airborne impurities, keeping your indoor air fresh. A 24-hour programmable timer means your room is already cool when you walk in, and the sleep mode quietly maintains your set temperature overnight.
No permanent installation needed, just position it near a window, attach the included exhaust hose kit, and start cooling within minutes. Backed by Whynter's 1-year warranty with a 3-year warranty on the compressor, the ARC-1280WX is built to last. If you're looking for a reliable, free-standing portable air conditioning unit that you can move room to room without any permanent modifications, the ARC-1280WX delivers the performance and convenience you need.

FAQ
How large of a room can the Whynter ARC-1280WX cool?
The Whynter ARC-1280WX is designed to cool rooms up to 500 sq. ft. It is ideal for bedrooms, living rooms, home offices, apartments, studios, and other medium-sized indoor spaces. Actual cooling performance depends on factors such as insulation, ceiling height, sunlight exposure, humidity, and ambient temperature.
What is the cooling capacity of the ARC-1280WX?
The ARC-1280WX delivers 13,000 BTU ASHRAE cooling capacity and 10,000 BTU SACC. These ratings reflect different testing standards and help customers compare portable air conditioner performance.
What makes the ARC-1280WX different from a traditional portable air conditioner?
The ARC-1280WX features advanced inverter technology that adjusts compressor speed according to cooling demand rather than relying exclusively on repeated full-power on/off cycles.
This helps deliver more consistent temperatures, quieter operation, and improved energy efficiency compared with conventional fixed-speed cooling systems.
Does the Whynter ARC-1280WX have a dual hose system?
Yes. The ARC-1280WX uses a dual hose ventilation system with separate air intake and exhaust pathways.
This configuration helps reduce negative indoor air pressure compared with typical single-hose portable air conditioners and supports efficient room cooling.
Can I control the ARC-1280WX using my smartphone?
Yes. The ARC-1280WX features smart Wi-Fi connectivity and supports remote operation through the NetHome Plus app.
You can adjust compatible settings using your smartphone, providing convenient climate control even when you are away from the unit.

Does the ARC-1280WX work as a dehumidifier?
Yes. The ARC-1280WX features a dedicated dehumidification mode capable of removing up to 96.8 pints of moisture per day under rated conditions.
This helps reduce excess moisture in humid indoor environments.
Does the ARC-1280WX have a fan-only mode?
Yes. The ARC-1280WX offers four operating modes:
- Auto
- Cool
- Dry (Dehumidify)
- Fan
Fan-only mode circulates indoor air without actively cooling the room.
Does the ARC-1280WX have a heating function?
No. The ARC-1280WX does not include a heating mode. It is designed for cooling, dehumidification, and air circulation.

Whynter lists operating noise levels of approximately:
- Low: 50 dBA
- Medium: 53 dBA
- High: 56 dBA
Actual perceived noise depends on the selected operating mode and surrounding environment.
Does the ARC-1280WX need to be drained manually?
The ARC-1280WX uses a self-evaporative condensate management system that helps exhaust collected moisture automatically in most operating environments.
In particularly humid conditions, additional drainage may be required. The unit includes upper and lower drain ports for appropriate drainage configurations.

No. The ARC-1280WX is a portable air conditioner that does not require permanent installation.
However, proper window ventilation is required during cooling operation. The unit includes an exhaust/intake ventilation setup and an adjustable window installation kit.
What size window kit is included?
The ARC-1280WX includes an adjustable window kit with a maximum length of approximately 82 inches, making it suitable for many common vertical and horizontal sliding window configurations.
Always measure your window opening before installation.
How long are the exhaust hoses?
The ARC-1280WX features extendable ventilation hoses with a maximum length of approximately 60 inches.
For optimal performance, keep the hoses as short and straight as practical and avoid unnecessary bends or extensions.

How do I clean and maintain the ARC-1280WX filters?
Turn off and unplug the air conditioner before maintenance.
Remove the washable filter, clean it according to the user manual, and allow it to dry completely before reinstalling.
Inspect the carbon filter regularly and replace it when necessary rather than assuming it can be washed.
What refrigerant does the ARC-1280WX use?
The ARC-1280WX uses R32 refrigerant, a refrigerant with lower global warming potential than older R410A systems.
Can the ARC-1280WX automatically restart after a power outage?
