When people are looking for the best air purifier that can be the best air purifier for baby that can double as the best car air purifier, they probably want something lightweight and powerful enough. The Airthereal ADH80 may be that purifier, as it has an area coverage of 160 square feet.\r\n\r\nWhy We Like It - Airthereal ADH80\r\nThe Airthereal ADH80 air purifier can be used in places such as various smaller rooms in the house, and in the car with a DC car adapter. It also has a larger than normal filter that can hold more contaminants, and there\u2019s an air quality monitor that automatically adjusts the fan speed.\r\n\r\nPower\/speed\r\nSince it has a true HEPA filter, a 3 filtration stage filter, Airthereal air purifiers offer fresh air along with a fan with speed settings. The filter is used to purify the air of contaminants that are as small as 0.3 microns. In comparison, the Rabbit Air MinusA2 purifier has a 6 filtration stage filter, and can deal with particles as small as 0.1 microns. Both purifiers have a pre filter and a carbon filter to help collect the contaminants.\r\nEfficiency(room size etc.)\r\nThe day dawning ADH80 air purification area coverage is 160 square feet, which is a lot less compared to the Levoit LV-PUR131S purifier, which has an area coverage of about 900 square feet. The ADH80 is at its most efficient when used for small and medium sized spaces such as cars and bedrooms. In bigger areas, the contaminants would be harder to capture, and it would take longer for the area to have significantly cleaner air.\r\nVersatility (HEPA, what does it filter, odor reduction etc.)\r\nSince it\u2019s a true HEPA air purifier, it has the ability to filter through a variety of air contaminants. It can capture dust, pollen- basically any contaminant that\u2019s no smaller than 0.3 microns (500 times smaller than a strand of human hair). Also, due to having a car adapter included with the purifier, it can also be used in the car, allowing the user to drive anywhere they want to go and can take the purifier with them.\r\nDurability\r\nThe purifier weighs only 3.5 Lbs., weighing less than the Levoit H132 purifier, which weighs 6.29 Lbs. Since it\u2019s an air purifier, it will inevitably have weak points to allow the air to travel through it in order to be filtered, especially since it\u2019s a cheaper priced purifier. However, since it\u2019s a smaller purifier with a smaller fan, those external weak points are also smaller and have more distance between them.\r\nValue\r\nAlthough basic air purifiers are simple devices in general, there are useful additions that can provide extra convenience. In addition to the air filter that has the ability to capture contaminants that are smaller than human hair, it also has an air quality monitor that can automatically adjust the fan speed, and a child-lock to prevent smaller children from changing the purifier\u2019s settings. Those features are arguably what affects the cost the most.\r\nAirthereal ADH80 Wrap Up\r\nCustomer reviews have mostly been positive, praising the ADH80 true HEPA purifier for its smaller size and bigger filter. One reviewer addressed how it\u2019s great for a small office, and that it was able to purify the air in about an hour despite being set to a lower setting.
