Cooling Efficiency and Capacity
Both the Keystone 12 and ZAFRO boast a cooling capacity of 12,000 BTU, suitable for cooling spaces up to 550 square feet.

It features a smart remote that takes room temperature and adjusts the cooling accordingly, enhancing user convenience.

The ZAFRO's silent operation at a minimum sound level of 45dB adds an extra layer of comfort, especially in quiet environments.
Energy Efficiency
Energy efficiency is crucial for long-term savings, and both units have features aimed at reducing energy consumption. The Keystone 12 includes an energy saver mode and a programmable 24-hour timer, which allows users to customize their heating and cooling preferences according to their schedules. Meanwhile, the ZAFRO air conditioner emphasizes its eco-friendly design with an energy-saving mode that ensures less electricity use without compromising cooling power.
