- “Easy installation. I had to trim the window vent down a little so it would fit properly, used a jig saw to easily trim it. I’ve had it installed and running for a week now, it’s not super quiet, but what air conditioner is. The noise is just a little more than a fan running. I’ve been using it to cool an 140 sq. ft. room and it does a good job. It’s been solely in the AC mode and after a week of running, the water still has not needed to be emptied and it has kept the room at the desired tempera”

Head-to-Head Comparison
When comparing the Kenmore KM8K and the ZAFRO Portable Air Conditioners, both 8,000 BTU units aim to provide relief from the heat in rooms up to 350 sq. ft. However, their fundamental differences in design and functionality lead to distinct advantages and use cases.
Cooling Performance and Capacity
Both units carry an 8,000 BTU rating based on the ASHRAE standard, which is a widely accepted measure for cooling power. This means, in terms of raw cooling potential, they are very comparable for their intended room size. However, the ZAFRO unit also provides a SACC (Seasonally Adjusted Cooling Capacity) rating of 5,000 BTU. Portable air conditioners typically have lower SACC ratings than their ASHRAE ratings, a common industry practice. This distinction is important because SACC is often considered a more realistic measure of performance in real-world conditions. The Kenmore KM8K, as a window unit, doesn’t typically list a SACC rating, but its CEER of 10.9 suggests good energy-efficient cooling. For pure cooling power in its designated room size, expect both to perform similarly, though the ZAFRO’s SACC rating provides a more nuanced view of its efficiency under varied conditions.
Versatility and Functionality
This is where the ZAFRO Portable Air Conditioners pulls ahead significantly. Its 3-in-1 functionality, offering cooling, dehumidifying, and fan modes, makes it a more versatile appliance. The dehumidifier function is particularly valuable in humid climates, helping to reduce moisture in the air even when the temperature isn’t excessively high. The Kenmore KM8K, on the other hand, is primarily a cooling unit. While it has Auto and Eco modes that contribute to comfort and efficiency, it lacks the dedicated dehumidifying capability. This makes the ZAFRO a more all-season solution, capable of addressing different comfort concerns beyond just temperature.
Installation and Portability
The most significant difference lies here. The Kenmore KM8K is a window air conditioner. This means it’s designed for permanent installation in a window, offering a streamlined look and freeing up floor space. However, it’s fixed to one location and might require some effort to install and seal properly. The ZAFRO Portable Air Conditioners, as the name suggests, is designed for mobility. With casters and handles, it can be easily moved between rooms. While it requires venting through a window using an included kit, this setup is generally straightforward and allows you to cool different areas as needed. For renters or those who need to cool multiple spaces at different times, the ZAFRO’s portability is a major advantage. For those who want a dedicated cooling solution for one room and prefer a more permanent, unobtrusive fixture, the Kenmore is the better choice. Learning how portable air conditioners work is key to understanding the venting process.
User Experience and Features
Both units offer user-friendly digital controls and remote operation, ensuring convenience. The Kenmore KM8K has three fan speeds, offering slightly more granular control over airflow compared to the ZAFRO’s two. However, the ZAFRO includes a 24-hour timer, a feature that the Kenmore KM8K lacks. This programmable timer is a significant convenience for scheduling cooling cycles, enhancing energy efficiency and comfort. Both units feature a Sleep Mode for quieter, more comfortable night-time operation. The Kenmore also boasts an auto-restart function, which is excellent for maintaining settings after power outages. The ZAFRO’s auto-shutoff feature adds a layer of safety and protection for the unit itself.
Energy Efficiency and Maintenance
The Kenmore KM8K has a listed CEER of 10.9, indicating its energy efficiency. While the ZAFRO doesn’t list a CEER, portable ACs generally tend to be less energy-efficient than window units due to the heat generated by their internal components being exhausted through the same room. However, both units feature washable filters, which is a huge plus for reducing ongoing maintenance costs and improving air quality. The ZAFRO’s water full indicator is a practical feature for managing drainage, especially in humid environments, which is a consideration for portable units.
Noise Levels
Customer feedback on noise can be subjective. While the ZAFRO Portable Air Conditioners is rated at 53 dB or less, which is generally considered quiet, one user mentioned it’s “a lil loud nothing too crazy.” Similarly, a Kenmore KM8K reviewer noted the fan was “a little noisy” but the compressor was quiet. This suggests that while neither unit will be completely silent, the noise levels are likely within the acceptable range for most users, especially considering the cooling they provide. Portable ACs inherently have their compressors inside the room, which can contribute to noise.
Frequently Asked Questions
Q: Which unit is better for a rental apartment?
A: The ZAFRO Portable Air Conditioners is generally a better choice for rental apartments. Its portability means you can move it between rooms or take it with you when you move out. Window units like the Kenmore KM8K may require landlord permission and can be more challenging to install and remove.
Q: How important is the SACC rating for portable ACs?
A: The SACC (Seasonally Adjusted Cooling Capacity) rating is quite important for portable air conditioners as it provides a more realistic estimate of cooling performance in real-world conditions compared to the ASHRAE rating.

Q: Which unit is more energy efficient?
A: The Kenmore KM8K has a listed CEER of 10.9, which is a good indicator of energy efficiency. Window units like the Kenmore are often more energy-efficient than portable ACs of the same BTU rating because their heat-generating components are outside the conditioned space. While the ZAFRO unit offers features like a timer and sleep mode for energy saving, its overall energy consumption might be higher due to its portable design.
Q: My portable AC isn’t blowing cold air. What could be wrong?
A: If your ZAFRO Portable Air Conditioners (or any portable AC) isn’t blowing cold air, there could be several reasons. Common issues include the filter needing cleaning, the unit needing to be drained if the water tank is full, incorrect installation of the exhaust hose, or the room being too large for the unit’s capacity. For more detailed troubleshooting, you can refer to our guide on portable AC not blowing cold air.
Q: Which unit is easier to maintain?
A: Both units feature washable filters, which simplifies maintenance. The ZAFRO Portable Air Conditioners has a water full indicator, which is a helpful alert for drainage.
