The basic thinking behind getting a portable AC unit for your home is that you\u2019ll be able to move it around from room to room. This gives you the advantage of placing the portable AC unit where you best see fit. Something else that you\u2019ve also got to give a thought to is how large your space is in terms of sq ft. If the square footage in your room is below or around 400 square feet, then the Whynter ARC 122DS single hose portable air conditioner might be worth considering. Is it the best portable air conditioner for RV? We think not, but if you\u2019ve been shopping around for the best dual hose portable air conditioner, you might have just stumbled upon a winner.\r\n\r\nWhy We Like It - Whynter Arc 122DS Elite\r\nThe Whynter ARC 122DS Elite is a well known portable air conditioner that\u2019s got what it takes to keep your room temperature well under control. It\u2019s got a dual hose system instead of a single hose, and is also backed by a 1 year warranty.\r\n\r\nPerformance\r\nWith an efficient cooling capacity of up to 12000 BTU, the Whynter ARC 122DS Elite is well equipped to handle midsize to large rooms, provided they\u2019re not larger than 400 square feet. The portable unit also takes up a lot more space than the compact Ontel Arctic Air Ultra air cooler, and operates based off of a dual hose system as opposed to a single hose configuration. This helps avoid the negative air pressure that\u2019s commonly found in single hose setups.\r\nEnergy Efficiency\r\nThe Whynter ARC AC unit has a Seasonal Energy Efficiency Ratio of 13, which is just above the minimum recommended of 10. This means that you shouldn\u2019t really expect your electricity bill to rise over an alarming rate, but if you want to keep things under your control, consider making use of the AC\u2019s 24 Hour Timer. This way, you\u2019ll be able to decide exactly when you need the dual hose portable air conditioner running, and for how long. We\u2019re a bit disappointed seeing that the costway portable air conditioner has a sleep mode but the Whynter ARC does not, but either way, there are a couple more features that make up for that lack.\r\nFiltration\r\nThe Whynter ARC 122DS portable unit stands out from a lot of other portable air conditioners due to the fact that it\u2019s got an activated carbon filter, while a lot of other portable ACs in the same category (such as the LG LP0817WSR 115v portable air conditioner) do not. This carbon filter helps rid the air coming from outside of any bad odours, making it breathable. In addition to that, there\u2019s also a washable pre filter that\u2019s used to prevent any dust from accumulating.\r\nDurability\r\nAs is the norm with most portable ACs, the Whynter ARC 122DS 12000 BTU portable air conditioner is backed by a 1 year limited warranty. This warranty covers both parts and labour, so if you happen to come across any issue with your unit upon purchase, do not hesitate to reach out to customer service.\r\nValue\r\nOne of the criteria that you\u2019re probably using to pick which AC unit you should go for is probably its noise level. Fortunately, the Whynter ARC 122DS is quiet enough not to wake you up at night, or even be a distraction in your living room. It\u2019s not louder than 52 decibels, thereby guaranteeing quiet operation.\r\nWhynter Arc 122DS Elite Wrap Up\r\nThe Whynter ARC 122DS features a remote control for convenient operation, as well as an extendable exhaust hose that makes installation a lot easier. The AC has also won numerous awards for its exemplary performance, so if you\u2019re looking to have an AC unit that\u2019s sure to deliver excellent service, go ahead and make an order for this one.
