There\u2019s a lot of categories around for the best air purifier these days. There\u2019s UV purifiers, plug-in purifiers, and even personal air purifiers. And if you decide you\u2019re looking for the best personal air purifier, then you would do well to consider the Dyson Cool Me for its low power consumption and long filter life.\r\n\r\nWhy We Like It - Dyson Cool Me\r\nThe Dyson Cool Me does double duty as both a personal fan and a personal purifier. The True HEPA Filter captures contaminants instead of just dispersing them like most other personal air purifiers and the Core Flow Technology blasts streams of cool air to wherever you want it to go.\r\n\r\nPower\/Speed\r\nThe Dyson Air Personal Purifying Fan is an excellent personal fan\/purifier combo that\u2019s adjustable so you can have air flow directly at you. The Core Flow Technology blasts concentrated cool air at you by pushing two streams of air together. If you prefer your air purification to be a little more traditional, try the AirTamer A310. On the plus side, power consumption on the Dyson is low and will only cost you about $12\/year to run.\r\nEfficiency\r\nDyson Pure Cool Air Purifiers are, by and large, personal air purifiers and thus won\u2019t have as great a coverage as dedicated room purifiers. However, the Dyson Cool Me may earn distinction here in that it doesn\u2019t give exact coverage. It\u2019s not even available on the Dyson site. Considering its size we\u2019re guessing 15-25 square feet, considering that\u2019s what most personal air purifiers cover. But check out the AVICHE Necklace Wearable Mini for something more concrete.\r\nVersatility\r\nThe Dyson Cool Me Personal Cooling Fan uses a True HEPA Filter for purified air free of pollen, bacteria, pet dander, and microns as small as 0.3 microns. If you\u2019d like something specifically for smoke, consider the Smoke Buddy Air Filter. The HEPA Filter life on the Dyson is also quite impressive. If you use it every day for 12 hours per day it should still be good for a whole year. More if you use it less than that!\r\nDurability\r\nThe Cool Me Personal Fan weighs only five pounds and should be easy to move from room to room, but not so easy to wear around your neck like most other personal air purifiers. It also has 10 adjustable fan speeds so you can set it to your own personal preference, but it\u2019s noise level hovers around 35-65dB. It\u2019s impressive for a fan, but a little loud for a personal air purifier.\r\nValue\r\nThe Dyson Link App isn\u2019t compatible with this model of Cool Me and neither is Alexa. Still, it comes with a remote control which will be essential in controlling the device since the onboard controls are rather limited. The Cool Me does come in white silver though, so at least there are options there. And despite its high price, it\u2019s always a good idea to review Dyson products for your air quality needs.\r\nDyson Cool Me Wrap Up\r\nIt\u2019s never a bad idea to go with a Dyson product, you just have to know what you\u2019re getting into. The Cool Me can\u2019t be worn around your neck like other personal air purifiers, and it\u2019s little loud considering it doubles as a fan, but its air purification abilities and long filter life are among the best we\u2019ve seen so far.
