AMAZING SYSTEM

[This review was collected as part of a promotion.] The box that came is HUGE! Make sure you have a good amount of space in your living space to put this! It is very strong! It does both heating and cooling as well as dehumidifying! A room warms/cools fairly quickly and it is AMAZING

Portable high performance and quiet

[This review was collected as part of a promotion.] I was gifted this keystone 10,000 BTU by Influenster. I have to say that after using this system love this portable air conditioning already. It's very quiet. it can be moveable to any room. We use it for the bedroom upstairs because it is the hottest room in the home and instead of turning the air conditioner in the whole house, having this air conditioner saves us a lot of energy Turing on the AC in spaces we not necessarily need. The portable keystone 10,000 BTU is big enough for our master bedroom. It has immediate cooling once turn on. It comes with a remote that I could control the temperature to comfort degrees I want. This keystone portable air conditioner is modern and comes in a sleek design, it's not bulky and has wheels if I want to transfer the air conditioner into a different room. The sleek design fits well in any room. What I love most is that it's ventilation is designed to get rid of humidity and keep the room cooling without feel damp. Filter is reusable and can be clean every 2-3 weeks. I highly recommended this keystone air conditioner for those who is looking for a portable conditioner system that is strong, convenient and affordable!

Keeps it cool and not too loud.

[This review was collected as part of a promotion.] I received this item for a review. I really do like this portable AC. It cooled our room and it wasn't too loud. It was pretty easy to install. The one thing I wish was that the exhaust vent wasn't so bulky.
