Looking for the best air purifier for a living room? You don\u2019t have to shell out hundreds of dollars for the best large room air purifier money can buy\u2014just trust the Blue Pure 121. It handles large rooms beautifully, thanks to its CFM rating, one button control, and 360-degree air flow.\r\n\r\nWhy We Like It - Blue Pure 121\r\nThe Blue Pure 121 has such a strong air delivery rate, it makes it all the more incredible with its 360-degree air flow system. It covers large areas, up to 620 sq ft, with ease\u2014and it\u2019s energy efficient.\r\n\r\nPower & Speed\r\nCompared to the Levoit Core 300, the Blue Pure 121 has almost twice as much CFM. Its peak performance is 400 CFM, yet has a very quiet operation. That kind of power further helps it filter out the current air several times in one hour; in fact, the Pure 121 issues five air changes per hour, so air quality is almost always being improved.\r\nEfficiency\r\nThe Blue Pure 121\u2019s big boy power does help it cover a lot more square footage. For the best performance, its room size limitations is 620 square feet. Anything more than that and you might as well go with the Alen BreatheSmart Classic Large Room Air Purifier. The Pur 121\u2019s power is also easy on energy, which you can see by its Energy Star certification.\r\nVersatility\r\nOn top of having great power, the Pure 121 compounds its performance with two fantastic design features: a 3-stage filtration system and 360-degrees of air flow. It starts by sucking in air, in a 360-degree flow, straight to fabric pre filters (and washable), which handle large particles. The particle filter handles dust, dust mites, pollen, and even pet dander, while the activated carbon filter handles odors caused by your pets, kitchen smells, and smoke. The particle carbon filter is fantastic, but it isn\u2019t True HEPA technology, not like the Coway Airmega 400 uses.\r\nDurability\r\nThe diva Blue Pure 121 isn\u2019t just powerful, but also well-built. It has a steel mesh for the lower housing, which keeps the filter from rattling around inside. And the chassis is a hard, high-impact plastic to keep the motor protected and overall sturdiness.\r\nValue\r\nWho is this for, then? Living rooms, kitchens, and similarly sized rooms. We understand $450 is a lot to drop on an air purifier, but its design and overall power definitely warrant it. The fact that you\u2019ll almost always be breathing clean air is a godsend\u2014especially if you live in the city. Just remember filter replacements are necessary.\r\nBlue Pure 121 Wrap Up\r\nEverything the Blue Pur 121 does is of high quality, from its low noise levels, to its air flow performance. Sure, a True HEPA filter would\u2019ve been better, but it has a filter to act in a similar fashion. It has a quiet operating, it\u2019s incredibly efficient, and has a 360-degree air flow design for better coverage.
