Finding the best windowless air conditioner for your home really isn\u2019t as difficult as most people make it out to be. You only need to have a good idea of how big your room is, as well as the kind of cooling power that would be ideal given the region that you live in. The Serenelife Portable Air conditioner for example has a rating of about 8000 BTU, making it suitable for rooms of up to 250 square feet in size. The portable air conditioner won\u2019t do much in a room that\u2019s larger than that size, so if your living room or office is just about the same size, go ahead and get to the end of this review to see what else it\u2019s got in store for you.\r\n\r\nWhy We Like It - Serene Life Portable Air Conditioner\r\nThe Serene Life Portable Air Conditioner is easily capable of keeping your 250 sq ft house or well cooled, and has an airflow capacity of up to 293 Cubic Meters per hour. It\u2019s got 3 functional modes, an easy to use control panel, and the capacity to remove up to 1.2 Litres of water per hour from the moisture.\r\n\r\nPerformance\r\nThe Serene Life portable air conditioner has got 3 operating modes. Aside from being able to fan you, it\u2019s got a built in dehumidifier, as well a cooling function. In this respect, it is similar to the Whynter ARC-14S 14,000 BTU Dual Hose Portable Air Conditioner, as they both have those three functions in common. The Serene Life room air conditioner also features a digital touch button control panel where you\u2019ll find settings for the power, mode, time, temperature and fan modes, making it a lot easier to control.\r\nEnergy Efficiency\r\nIn regards to energy efficiency, the SereneLife portable AC unit has a rated power of 1100 Watts on its highest settings, and about 700 watts on its lowest, so if you really want it to be energy efficient, you\u2019re going to have to be very keen on your usage. It\u2019s got a decent Energy Efficiency Ratio of about 8.9, which matches that of the Black + Decker BPACT08WT Portable Air Conditioner, meaning you should expect the same level of power consumption from the two portable air conditioning units.\r\nFiltration\r\nTo keep out any dust particles and unwanted materials from clogging up the inside of the Serenelife Portable Air Conditioner, it comes with a filter that you\u2019ll be able to easily remove and wash. Unfortunately, there\u2019s no check filter indicator, so you\u2019ll just have to make sure that you\u2019re able to wash it within a recommended period of every 45 to 90 days. As long as you keep the portable air conditioner well maintained through constant cleaning, it should maintain good performance over a long period of time.\r\nDurability\r\nLike most portable air conditioners of its capacity, the Serene Life air conditioning unit is backed by a 1 year warranty that you can easily claim in the event that your unit arrives with any problems. This is the same period that the Honeywell MN10CESWW, and it happens to be the industry standard for most air conditioning units.\r\nValue\r\nThe one thing that a good number of people might probably find to be impressive about the Serene Life portable AC is that it comes with a window kit that allows you to hook up its exhaust hose appropriately into your window, and in doing so, you\u2019ll be able to have the AC unit easily pull warm air from your room, and replace it with cool air. The 8000 BTU Portable air conditioner also has a considerably low noise level, making it perfect for use during the night, and also comes with a remote control to facilitate remote operation.\r\nSerene Life Portable Air Conditioner Wrap Up\r\nThere aren\u2019t as many air conditioning units that come with an installation kit, but the Serene Life Portable AC unit happens to be one of them. This means you won\u2019t have to purchase anything required to get it set up from outside, saving you the extra cost of having to do so.
