If your idea of the best air purifier is one that covers large areas, the Rabbit Air Minusa2 Ultra Quiet HEPA Air Purifier makes a good argument for the best large room air purifier. It handles 815 square feet with ease. It also has six stages of air filtration, one of which is an alternative to True HEPA filters.\r\n\r\nWhy We Like It - Rabbit Air Minusa2 Ultra Quiet HEPA Air Purifier\r\nThe Rabbit Air Minusa2 Ultra Quiet HEPA Air Purifier rocks the boat by introducing not three, but six stages of filtration, including modern features like Auto Mode, Sleep Mode, and Wi-Fi connectability.\r\n\r\nPower & Speed\r\nThere\u2019s some really good power behind this machine. Crank it to the highest fan speeds and it can achieve 200+ CFM, which isn\u2019t the fastest nor exceptionally powerful, but still good nonetheless. It isn\u2019t entirely concerned with speed as it is with quality.\r\nEfficiency\r\nTo put that power into perspective, RabbitAir Minusa2 Air Purifiers can handle purifying air in a room as big as 815 square with incredible ease. More importantly, it has four air changes per hour, meaning you have a batch of new air every 15 minutes. However, the Coway Airmega 400 covers 1560 square feet, almost twice as much.\r\nVersatility\r\nCompared to the Alen BreatheSmart Classic Large Room Air Purifier, the purifier Rabbit Air Minusa2 SPA-780N has three more filters for particles to pass through. In other words: 6-stage air purification HEPA filtration. For clean air quality, the pre filter traps large particles first, then the medium filter handles pet allergens, mold, and anything too small for the pre-filter. The BioGS HEPA filter does away with virus particles, allergens, mold, and 99.97% of other nasty particles as small as 0.3 microns. The fourth filter can be Germ Defense, Toxin Absorber, Odor Remover, or other customizable filters offered by Rabbit Air, though the activated carbon filter does handle most harmful oors. The ion generator actually traps particles or lets them fall to the floor for the vacuum to handle.\r\nDurability\r\nAnother reason Rabbit Air Minusa2 Ultra Quiet HEPA Air Purifier has a higher price tag is through its use of higher quality materials. It\u2019s one sturdy piece of equipment. You\u2019ll understand once you realize its maximum weight is under 20 lbs. So if you mount it, don\u2019t forget to use anchors.\r\nValue\r\nThere\u2019s so much to like about the Rabbit Air Minusa2 Ultra Quiet HEPA Air Purifier. Its unique 6-stage filtration system is by far its greatest asset for cleaning the indoor air. It comes with a light sensor, mood lighting, and an indicator light for reminding you of replacements. Unfortunately, these air purifier types and filter replacements tend to be expensive, and it is. If you aren\u2019t ready to spend that kind of money, and need something smaller, the Levoit Core 300 is $100.\r\nRabbit Air Minusa2 Ultra Quiet HEPA Air Purifier Wrap Up\r\nThe biggest thing holding the Rabbit Air Minusa2 Ultra Quiet HEPA Air Purifier back is its price. However, in the end its price is warranted in the right hands. This is the kind of powerful air purifier you get when you\u2019ve already settled with their purpose. It\u2019s hard to pass on so many filters in one sleek, compact machine.
