Dreo Portable Air Conditioners, 8000 BTU ASHRAE (5000 BTU DOE) Smart…

𝗨𝗹𝘁𝗿𝗮 𝗣𝗼𝘄𝗲𝗿𝗳𝘂𝗹 𝗜𝗰𝗲𝗖𝗼𝗼𝗹 𝗦𝘆𝘀𝘁𝗲𝗺: Increase coverage up to 14 ft. away with this 8000 BTU ASHRAE (5000 BTU SACC) portable air conditioners and its best buddy, the fan, giving you instant chills even in hot summer days. Additionally, you can keep the temperature between 61°F to 86°F using various controls to tailor the cooling to your preferences.

Compact & Portable Design

The Dreo AC318S is designed with portability in mind. Its sleek, modern exterior fits well in bedrooms, small apartments, offices, or dorms. Four smooth-rolling caster wheels make it easy to move from room to room, eliminating the need for multiple fixed AC units.

The included window kit allows quick installation in sliding or double-hung windows, while the drainage-free system eliminates the need for constant water emptying, making it far more convenient than older models.

Cooling Power – 8,000 BTU (ASHRAE) / 5,000 BTU (DOE)

This unit provides 8,000 BTU (ASHRAE) of cooling power, equivalent to 5,000 BTU under DOE standards, making it ideal for:

Bedrooms up to ~250 sq. ft.
Small living rooms or home offices.
Apartments, dorms, or rental units.

It cools quickly, bringing room temperatures down within minutes, and maintains consistent comfort even during warmer summer days.

Drainage-Free Cooling

One of the standout features is the self-evaporative system that recycles condensation, eliminating the hassle of manual drainage in most conditions. For bedrooms and small spaces, this means truly hands-off operation, with little to no need to empty water.

In extremely humid environments, occasional drainage may be required, but for typical use, it’s virtually maintenance-free.

Whisper-Quiet Operation – 45dB

Noise is a big factor when choosing a bedroom AC. At just 45dB on its lowest setting, the Dreo AC318S is significantly quieter than most portable AC units.

This makes it an excellent choice for:

Light sleepers who need quiet nights.
Home offices where noise can interfere with calls or focus.
Apartments where noise levels may disturb neighbors.

Even at higher speeds, the noise level remains manageable, producing a gentle hum rather than a disruptive roar.

Smart Controls – App, Voice, and Remote

The Dreo AC318S is built for smart living. You can control it in multiple ways:

Dreo App – Adjust modes, set schedules, and monitor cooling from your phone.
Voice Assistants – Compatible with Alexa and Google Assistant for hands-free control.
Remote Control – Convenient when you don’t want to reach for your phone.
Touch Panel – Simple, intuitive interface on the unit itself.

This flexibility makes it far more user-friendly than traditional portable ACs, especially for busy households or tech-savvy users.

Multiple Modes & Functions

The AC318S is more than just a cooler—it’s a versatile comfort machine with different operating modes:

Cool Mode – Fast, efficient cooling for hot days.
Fan Mode – Circulates air without cooling.
Dry Mode – Acts as a dehumidifier in damp conditions.
Sleep Mode – Quiet, energy-saving cooling ideal for overnight use.

Each mode can be adjusted through the app, remote, or voice commands, giving you complete control over your environment.

Energy Efficiency

With inverter-grade efficiency in a portable design, the Dreo AC318S helps keep energy costs under control. Features like Eco Mode and Sleep Mode ensure that the unit cools effectively without overconsuming electricity.

For renters and homeowners who want targeted cooling without installing central air or window units in every room, this portable solution is both cost-effective and environmentally friendly.

Airflow & Comfort

The wide-angle swing louvers help distribute cool air evenly across the room. Instead of blasting cold air in one direction, the AC spreads it throughout the space for balanced comfort.

This ensures you don’t end up with hot spots in corners, making the cooling feel more natural and consistent.

Installation & Setup

Setting up the Dreo AC318S is straightforward:

Attach the included window exhaust kit.
Plug the unit into a standard outlet.
Control settings via the app, voice assistant, or remote.

No permanent installation is required, which makes it perfect for renters or those who frequently move between rooms.

Real-World Performance

In everyday use, the Dreo AC318S excels in small-to-medium rooms:

Bedrooms cool down quickly, making it easy to sleep comfortably.
Home offices stay quiet and cool during long work sessions.
Living rooms up to ~250 sq. ft. maintain steady comfort even on hot afternoons.

The smart scheduling feature via the app lets you pre-cool rooms before you arrive, while the drainage-free design keeps maintenance simple.
