Bissell Air320<\/figcaption><\/figure>\nAir320<\/strong> \nAs for the Air320, expect a lot of work out of the larger unit. With its powerful fan, the Air320 can be the perfect device for rooms of up to 1,000 square feet. It can work in smaller spaces like bedrooms or even bathrooms, but to make use of its tremendous purifying performance, 900 to 1,000 square feet is ideal. <\/p>\nConclusion<\/strong> \nWe don\u2019t decide whether large is better or not for your unique situation, so you have to measure the room manually. Their 200-square-foot disparity can mean a whole lot in terms of wasted potential or not having enough purifying power. As the adage goes, measure twice and purchase once.<\/p>\n3-Stage Filtration<\/h3>\n Air220 and Air320<\/strong> \nBoth devices use identical filtration systems, starting from a pre-filter for capturing visible pollutants, a HEPA filter for trapping microscopic particles (0.3 microns) up to 99% of the time, and finally, an activated carbon filter shaped like a honeycomb for trapping odor molecules and VOCs. Their 3-stage filtration systems are perfect for residential settings. Neither of them comes with an ionizer or UV-C beam. <\/p>\nBissell Air220<\/figcaption><\/figure>\nPre-Filter<\/h3>\n Air220<\/strong> \nEven though the two air purifiers use identical filtration systems, that\u2019s not to say they are identical in every way. The big difference between them is their pre-filters; the Air220 is a solid panel with thousands of punched tiny holes. A solid metal or plastic panel is easy to wash, scrub, rinse, and dry.<\/p>\nAir320<\/strong> \nThe Air320\u2019s pre-filter, on the other hand, is made of an elastic fabric that works as a fine mesh. After testing them out in identical scenarios, the fabric pre-filter of the Air320 worked a lot better at trapping visible particles, but as you can imagine, it was a lot harder to clean.<\/p>\nConclusion<\/strong> \nEasy-to-clean versus better-pre-filtration. It’s up to you to decide whether you can live with constantly washing the Air320\u2019s fabric pre-filter or not, but the good news is that both of them work beautifully at filtering large and small particles.<\/p>\nNoise Production<\/h3>\n Air220<\/strong> \nHow much noise the air purifier produces is an extremely important factor when shopping for the right device. If you place the air purifier in the bedroom, the last thing you need is to yodel long into the night and disturb your beauty sleep. The Air220 generates between 34 and 51 decibels \u2013 the loudest being equivalent to normal household background sounds.<\/p>\nBissell Air320<\/figcaption><\/figure>\nAir320<\/strong> \nThe Air320 isn\u2019t that different from the Air220 in terms of noise production. On its quiet setting, it drones at a low 37 decibels, and its highest fan speed is only 59 decibels. As the large air purifier, it makes sense for the device to produce louder sounds, but once again, the differences between the two are almost negligible.<\/p>\nConclusion<\/strong> \nSo if the noise level differences between the Air220 and Air320 are not very different, why bring it up in the first place? Because the products’ airflow capacities don\u2019t make a difference in the average-sized bedroom, 3 decibels can mean a lot to sensitive sleepers. In this case, the Air220 would be the better option, admittedly by a very narrow margin.<\/p>\nAutomated Night Light<\/h3>\n Air220 and Air320<\/strong> \nAnd while we are on the topic of sleep, we might as well bring up that both of these air purifiers have sensors that detect the presence of light in the room. When the sun goes down, the lights are dimmed. The Air220 and Air320 will automatically shut off their LEDs based on the assumption that it is nighttime. <\/p>\nYou don\u2019t need to get up out of bed and risk ruining your sleepiness to shut off the device\u2019s nightlight. There’s a handy feature for those who don\u2019t appreciate blinding LEDs in the bedroom.<\/p>\nBissell Air220<\/figcaption><\/figure>\nCirQulate System<\/h3>\n Air220 and Air320<\/strong> \nOur readers will be thrilled to learn that the Air220 and Air320 come with the CirQulate System pre-installed and ready to roll. You might be more familiar with this as a real-time indoor air quality monitor is constantly on the hunt for airborne particles. <\/p>\nAs soon as the indoor air quality reaches a certain degree, these devices will kick into high gear to eradicate any pesky particles as quickly as possible. With the CirQulate System, what you need to do is to plug the device in, switch to auto mode, and let the air purifier do its thing.<\/p>\n\n
