The best 4 in 1 portable air conditioner.
It's a heater, dehumidifier, air conditioner and a fan.
This is a slim model but I wish it to be even slimmer.
Posted 1 year ago - I love this unit as an Air conditioner best. There is no way to test the heating until winter so I will leave that review for now. I have a 12.5 x 16 formal dinning room previously installed with a 7000 BTU window air conditioner. It gets warm in summer even with the window air conditioner on full power. I replaced it with this and the difference is great. Having two vents really cool the room much faster then the window unit. With a rating of 10EER and I have less to worry about wrecking up my electricity bill. It's self-evaporative technology means I don't have to empty a water filled bucket like other models does - the water taken out of the air is vented out the window. The room dehumidifies quickly so when the summer get cooler but humidity stays high I would turn off the air conditioning and just use the humidifier. It sucks up a whopping 4.2 pints an hr. or 100 pints a day. That's the best rate comparing with others. Remember window units are more efficient and cheaper to buy but if you need a portable unit this is the one. I have no regrets with this buy and I highly recommend this Royal Sovereign ARP-5012XH.
