10 Best Portable Air Conditioner Without Pipe 2025 in the United States

The BLACK+DECKER 10,000 BTU Portable Air Conditioner is a versatile unit designed for rooms up to 450 sq. ft. One of its standout features is the 3-in-1 functionality, allowing it to act as an air conditioner, dehumidifier, and fan. This can be particularly useful in varying weather conditions.

The cooling capacity of 10,000 BTU ensures efficient cooling for medium-sized rooms, and the unit is equipped with a remote control and an LED display for easy operation. It's also portable, thanks to the casters and side handles, making it convenient to move from room to room. The auto water evaporation and washable filter add to its ease of maintenance.

However, there are a few drawbacks. The noise level at 52 dB might be noticeable, especially in a quiet bedroom setting. Additionally, the energy efficiency ratio (EER) of 6.7 is on the lower side, which could result in higher energy consumption compared to more efficient models. The water tank capacity is also relatively small at 0.45 liters, meaning it may require frequent emptying in humid conditions. Despite these limitations, the BLACK+DECKER portable air conditioner offers a good mix of functionality and convenience, making it a suitable choice for those needing a flexible cooling solution for medium-sized spaces.

The Dreo Portable Air Conditioner offers a solid 10,000 BTU cooling capacity (6000 BTU SACC) which suits small to medium rooms up to about 200 square feet, making it a good pick for bedrooms or personal spaces. Its noise level is impressively low at 45 dB, which means it’s quiet enough for sleeping or working without disruption. One standout feature is the patented drainage-free cooling system that evaporates moisture automatically, so you don’t need to worry about emptying a water tank frequently, especially in humid conditions up to 90% humidity. The unit is also energy efficient with a SEER rating of 6.51, helping keep electricity use reasonable.

Portability is well thought out with smooth caster wheels and modular window panels that fit various window sizes, plus an exhaust hose for drainage if needed, although this may add complexity for some users. It integrates smart controls via app, voice assistants (Alexa, Google Home, Siri), and remote, which makes adjusting settings convenient, even allowing you to customize cooling and humidity levels. The 3-in-1 function (cooling, fan, dehumidifier) adds versatility for different weather conditions.

The product weighs about 57 pounds, so it’s portable but may require some effort moving between rooms. While it doesn’t need an exhaust pipe for typical drainage, the inclusion of a hose might confuse users expecting a fully pipe-free setup. Customer support and a 1-year warranty provide peace of mind. This portable AC is well suited for users wanting quiet, efficient, and flexible cooling without the hassle of traditional pipe installations, though it may be less ideal if you want ultra-simple setup without any hose at all.

The Whynter Portable Air Conditioner with a cooling capacity of 14,000 BTU is designed to effectively cool spaces up to 500 square feet. This is quite powerful and suitable for larger rooms or open-plan living areas. One standout feature is its dual-hose system, which enhances cooling efficiency and speed. It also functions as a dehumidifier, capable of removing up to 71 pints of moisture a day, making it a versatile choice for humid environments.

The built-in auto drain function is a convenient feature as it minimizes manual maintenance. It operates quietly at a noise level of 51 dBA, which is relatively low and ideal for bedrooms or living rooms where silence is appreciated. However, the energy efficiency ratio (EER) is 7.69, which isn't the highest in its category, potentially leading to higher electricity consumption over time. Another point to consider is that it lacks an Energy Star certification, which many consumers look for as a sign of energy efficiency. Portability is enhanced by its compact design (19
