Opting for an evaporative air cooler instead of an air conditioner has its own list of benefits that can be very beneficial to someone that\u2019s keen on energy efficiency as well as performance. An evaporative cooler like the Ontel Arctic Air Ultra for example provides a cooling effect through the process of evaporation, and this actually requires little to no electricity to take place. Aside from that, the Ontel Arctic Ultra evaporative air cooler also stands out because of its compact size, and this is one of the reasons why we think it stands a pretty good chance of being the best portable air conditioner for RV. Hang around and find out what else it\u2019s got in store.\r\n\r\nWhy We Like It - Ontel Arctic Air Ultra\r\nWeighing only 2.6 pounds, the Ontel Arctic Air Ultra is a small, compact air cooler that can be easily carried around, and used to supply cool air wherever you feel like you need to cool down.\r\n\r\nPerformance\r\nThe Ontel Arctic Air Ultra is the perfect alternative for anyone looking to have a personal space cooler that they can carry around or even place right next to them as they sleep or relax. It allows for 3 fan speeds (which is more than the two that you\u2019ll get from the Costway Portable Air Conditioner), and has also got a multi directional air vent that directs the flow of air. The Ontel Arctic portable air conditioner serves 3 functions, as it is able to cool, humidify and purify the air, making it a great bargain.\r\nEnergy Efficiency\r\nEnergy costs are a huge primary concern especially when you\u2019re dealing with air conditioners. It's one of the things that you\u2019ll have to look into if you want to keep your costs low, and fortunately, the Ontel Arctic Air Ultra air cooler doesn\u2019t need that much of it to function. Unlike the LG LP0817WSR 115v portable air conditioner, it relies on hydro-chill technology to pull in hot air through an evaporative air-cooling filter and instantly turn it into cool air. The only element that requires electricity in this process is the fan, so there isn\u2019t much air required in this process.\r\nFiltration\r\nThe evaporative water filter that\u2019s found inside the Ontel Arctic Air Ultra cooler makes sure that there aren\u2019t any unwanted particles that make their way through to your room once you turn the air cooler on. To make sure that the filters are able to maintain this function, you\u2019ll need to at least remove and wash it twice a month to keep it in optimum performing condition.\r\nDurability\r\nSimilar to the Whynter ARC 12D2S Elite, the Ontel Arctic Air Ultra is also backed by a 1 year warranty, so should you come across any issues with it when new. The cooler generally works great, provided you take good care of it by always keeping it clean.\r\nValue\r\nBeing an evaporative cooler, the Ontel Arctic Air Ultra does feature a water tank, and it has the capacity to run up to 8 hours with every refill. This is pretty good considering its small size, and on top of that, the unit also features soothing ambient lighting with a variety of up to 7 different options to choose from.\r\nOntel Arctic Air Ultra Wrap Up\r\nThe Ontel Arctic Air Ultra is pretty quiet in operation, so if you intend to use it at night, you\u2019ll be 100% guaranteed of no distractions from it.
