Everything you need for temp control

Bought this 4-in-1 last month in preparation for summer, but at the same time, wanting a product also usable in the winter as we live in a small apartment that doesnt have much storage space for unused electronics. Was a little skeptical because there werent a lot of reviews about it not to mention a couple of spelling errors and it took a while to be delivered. It was a huge risk to purchase it. The window installation was the trickiest part but as soon as the A/C kicked in, man it was great!!! The instructions were straightforward, easy to use, except when you want to connect it to the wifi. It comes with a remote control and in my opinion, the wifi function is not that necessary especially when you live in a small space. Whats even better about it is that the heater works great, too! The design is very sleek, fits in a corner and you can adjust however you like. The best thing is that it operates fairly quietly, the stand fan is louder than the A/C as long as it is on low. Price point is very competitive with all the branded units out there given its features. This truly is a quality product!

I would also recommend the small air purifiers because theyre small but very effective. In fact weve got 2 of them. I had one of them first before I stumbled upon the ultima cosa website and found this 4-in-1 portable A/C.

I love the 4-in-1

Rather than describing this machine as heating, cooling, dry, and wet, I believe it will not be as far of a stretch to say that it is straight up climate control for my room!

Beating this heatwave

I just HAD to buy an ac unit because of the heatwave climate going on in Ontario.... it really has been a lifesaver for my mental health and physical resting state. Works perfectly with a bit of noise and maximum output for high quality air conditioning for heat, cold, wet, and dry

Beautiful humming of this conditioner

Not totally there yet but neither is my air.... I guess this works for now but how much does air quality and temperature affect my mood? A LOT... this worth lol
