Picking the Best Air Purifier for versatility often leads to the machine lagging behind in other areas, but that doesn\u2019t seem to be the case with the Alen Breathesmart Classic large Room Air Purifier. It covers 1100 square feet quite efficiently, a sign you might have the best air purifier for mold and the best large room air purifier wrapped into one. So let\u2019s examine the entire package!\r\n\r\nWhy We Like It - Alen Breathesmart Classic large Room Air Purifier\r\nThe Alen Breathesmart Classic large Room Air Purifier combines a True HEPA filter, activated carbon filter, and a pre-filter with your choice of four specialized filters for a more unique approach to pure air filtration.\r\n\r\nPower & Speed\r\nUnlike other air purifiers, the Alen Breathesmart Classic is entirely automatic with its fan speeds, rather than manually. It senses the air quality around you and adjusts accordingly for a relaxed, hands-off experience. At the highest speeds, it can reach CFM as high as 300. However, unlike the Medify Air, it doesn\u2019t distribute the air 360-degrees, which could come in handy if you want the best whole house air purifier or the best air purifier for pets.\r\nEfficiency\r\nThat kind of power and speed might not sound ideal, but the Alen Breathesmart Classic opts for better airflow rather than relying solely on fan speed. Placed in the right position, it can cover a room the size of 1100 square feet. Compared to the Oransi Max HEPA Air Purifier, that\u2019s nearly twice as much coverage.\r\nVersatility\r\nThe Alen Breathesmart Classic can target specific particles and odors you\u2019d like to address, in addition to its True HEPA air filter and pre filter. If you live with animals, you\u2019ll be more interested in the HEPA Pure filter, capturing dust pollen, pet dander, and pet hair. The HEPA Silver filter targets dust, mold, mildew, and bacteria; HEPA Fresh Plus targets VOCs; and HEPA Odorcell captures odors from wet dogs, litter fumes, and even a teenager\u2019s room. Despite your choices, you\u2019re always getting clean air in return.\r\nDurability\r\nThese Alen air purifiers opt for tall and slender, rather than short and bulky. It measures 10 x 17.75 x 26.75 inches and weighs 21 lbs. That\u2019s not exactly light, but still speaks to its level of durability. It ultimately helps store, move, and position this HEPA air purifier Alen has designed.\r\nValue\r\nOn one hand, the Breathesmart air purifier is a great machine to have\u2014especially if your ultimate goal is for large areas of at-home air quality to be improved. Unfortunately, it\u2019s a heavy investment, considering replacement filters are expensive, though still cheaper than the Coway Airmega 400, but the Coway is also nearly $200 cheaper and covers more area.\r\nAlen Breathesmart Classic large Room Air Purifier Wrap Up\r\nWith the addition of a True HEPA filter, the Alen Breathesmart Classic Large Room Air Purifier knocked out its biggest flaw. Sure, replacement filters cost a pretty penny, but the pre-filter does wonders keeping filter life lasting longer. It covers large areas with ease and it\u2019s hands-off approach of automatically adjusting fan speeds is a nice touch.
