Trying to find the Best Air Purifier can be a daunting task considering the sheer volume of them out there. Should you get the best filterless air purifier, best ionic air purifier, or best plug in air purifier? Fortunately, there\u2019s the GreenTech Air Purifier which, despite some missteps, should cover at least one of these bases.\r\n\r\nWhy We Like It - GreenTech Air Purifier\r\nThe GreenTech Air Purifier is an absolute powerhouse for such a condensed little unit. It can cover a fairly decent room size that\u2019s even bigger than other air purifiers two or three times its size. Further, it can eliminate many different odors, from bacterias to pet danders, with ease.\r\n\r\nPower\/Speed\r\nGreentech Air Purifiers work fast and have a dial to adjust speed settings depending on the size of the room. Obviously, you\u2019d want smaller air purification settings for smaller rooms and high mode for larger rooms. It also works great if you want clean air on budget as it only consumes 3 watts of power when it\u2019s on. If you\u2019re interested, you can also check out the Airfree Air Purifier for fresh air on budget-level energy consumption too.\r\nEfficiency\r\nThe GreenTech Environmental PureAir can improve the indoor air quality of a room about 325 square feet. Compared to its competition, Such as the AirFree P100, this is actually quite impressive. It won\u2019t give you whole home coverage, but it will leave the room air of whatever room you put it in very fresh and clean.\r\nVersatility\r\nOne of the draws of this purifier is that it\u2019s filterless. You won\u2019t need to buy an expensive HEPA Filter, just wipe it down every once in a while as per the instructions. Make sure you consider the AirFree Iris 3000 for another type of air purifier where HEPA type filters aren\u2019t needed. The GreenTech is also able to destroy a large variety of contaminants, such as pet odors bacteria viruses, to leave your home air clean and breathable.\r\nDurability\r\nWeighing only 6.35 ounces and having dimensions of 2.5" x 3.5" x 4.25" the GreenTech is able to be taken almost everywhere you go, even a suitcase if you're travelling and want to set it up in a hotel room. However, it will last only a couple of months, tops, before it stops cleaning the air. Further, for such a small unit, you\u2019d be surprised how loud it can get.\r\nValue\r\nCustomer reviews on Amazon rate the GreenTech well with a 4.5\/5 star rating based out 692 reviews, and this is despite its short lifespan. And while many other GreenTech purifiers feature an away mode, this one doesn\u2019t. But that\u2019s okay because it\u2019s not the type of filter that will need to monitor itself while you\u2019re away. Although it\u2019s unavailable right now, it\u2019s only been around $50.00 traditionally so buying it and trying it won\u2019t eat away at your money.\r\nGreentech Air Purifier Wrap Up\r\nAir Purifier PureAir by GreenTech may not be the longest-lasting purifier, and it may be louder than you\u2019d expect for such a small unit, but it can purify any room with the power and versatility of air purifiers much larger than it. And at the end of the day isn\u2019t that what ultimately matters in an air purifier?
