Save $70: Right now, Amazon is offering Coolblus portable AC units for up to $70 off so you can stay cool this summer without overspending. These units are a great way to make yourself more comfortable as this year’s unseasonably hot weather continues.
The best part? These portable AC units are easy to pack and take with you if you’re relocating. Amazon’s deals tend to sell out quickly, so we suggest acting fast if you’re interested.
The cooling capacity of an AC unit is measured in BTUs (British Thermal Units). Bigger and more open spaces typically require models with higher BTUs.
If you have a large space or need a high-capacity portable AC unit, then this 15,000 BTU model for $400 is the way to go. This saves you $60 on a four-in-one unit that works as an AC, fan, dehumidifier and heater. You can control it via Wi-Fi and use this unit year-round. Plus, it’s powerful enough to make you comfortable in spaces up to 700 square feet.
This 14,000 BTU unit is suitable for spaces up to 650 square feet and costs $300, which saves you $60. It’s also a four-in-one portable unit with Wi-Fi connectivity that can be installed in either a vertical or horizontal window.
Amazon is also discounting this 10,000 BTU Coolblus portable AC by $70 right now, which brings it down to $230. It has enough power to cool rooms of up to 450 square feet, and provides all the same functions as the bigger units. There are several other models to choose from at Amazon, with average savings of roughly $60.
