10 Best Portable Air Conditioner For Small Room No Exhaust Hose 2025 in the United States

The BLACK+DECKER 10,000 BTU Portable Air Conditioner is designed for rooms up to 450 sq. ft., making it a suitable option for small to medium-sized rooms. Its 3-in-1 functionality as an air conditioner, dehumidifier, and fan adds versatility, allowing it to be used in various conditions. The remote control and top-mounted LED display make it user-friendly, and the mobility features like casters and side handles make it easy to move around the house.

The 24-hour timer and auto water evaporation are convenient additions, enhancing ease of use and maintenance. However, its Seasonal Energy Efficiency Ratio (SEER) of 6.7 is on the lower side, which could mean higher energy consumption compared to more energy-efficient models. The noise level of 52 dB is relatively quiet but may still be noticeable in very quiet environments.

The water tank capacity is quite small at 0.45 liters, which might require frequent emptying during high humidity. The installation kit includes necessary components, but it does have an exhaust hose, which conflicts with the no exhaust hose requirement. This unit is best suited for those looking for a portable air conditioner with multi-functionality and easy mobility but might not be the best choice for those prioritizing high energy efficiency or needing a large water tank capacity.

The BLACK+DECKER 8,000 BTU Portable Air Conditioner is a versatile option for cooling small rooms up to 350 sq. ft. Its cooling capacity of 8,000 BTU ensures that it can handle the size of the room efficiently. It's also a multifunctional unit that acts as an air conditioner, dehumidifier, and fan, making it a valuable addition to your home, especially during the hot summer months.

The 3-in-1 functionality and the inclusion of a remote control and LED display add to its convenience and user-friendliness. Mobility is another strong point, thanks to the casters and side handles that make it easy to move from room to room. It also comes with an easy-to-install window kit, although an exhaust hose is required for operation, which might be a drawback for those specifically looking for units without an exhaust hose.

With a noise level of 54 dB, it operates relatively quietly, but it might still be noticeable during quieter moments. The energy efficiency could be better, given its SEER rating of 5.4, which is on the lower side. The unit's design is compact and it has a clean, white finish which can blend well with most interior designs. The appliance is fairly heavy at 52.9 pounds, which might be an issue for some users despite its portability features. The BLACK+DECKER 8,000 BTU Portable Air Conditioner is a solid choice for those with small rooms, but the need for an exhaust hose and its energy efficiency rating are points to consider.

The Whynter Portable Air Conditioner 14,000 BTU is a high-performing unit recognized for its powerful cooling capacity, making it suitable for rooms up to 500 sq. ft. It boasts a dual-hose system and operates quietly at 51 dB, which is ideal for bedroom use. The built-in dehumidifier is a standout feature, capable of removing up to 71 pints of moisture per day, which is beneficial in humid environments. Additionally, it offers three operational modes: cooling, dehumidifying, and fan, providing versatility in its use.

The included window kit facilitates easy installation, and its eco-friendly R-32 refrigerant is a plus for environmentally conscious users. However, it does come with an exhaust hose, which contradicts the requirement for no exhaust hose. It is also relatively heavy at 73 pounds, which may limit its portability for some users. The unit has a Seasonal Energy Efficiency Ratio (SEER) of 7.69, which is not the highest, indicating moderate energy efficiency. It also lacks an Energy Star certification.

Despite these drawbacks, the features, including a washable pre-filter and activated carbon filter, make it a robust option for users seeking a reliable portable air conditioner for larger small rooms.
