The Sharp Plasmacluster FP-A80U Air Purifier is an exceptional entertainer, with a cost that reflects its high purification and builds quality. It exceeded both the Coway and Winix designs in particle purification, being available in second only to the Blueair. It was nearly the quietest, merely 1 dB louder than the Winix design, and it edged out both the Coway and Winix copies in the VOC relocation. It's an excellent entertainer, but the operating costs are a fair bit greater, about more peerless considering the expense of both electricity and filters.
Winix WAC5500 is a predecessor to the WAC6300. While we didn't test it, it's almost the same as the 6300 model we did test, with the primary difference being that the 5500 design consisted of a washable HEPA filter that can extend the life of the filter. These washable filters were a temporary fad and have fallen out of line now. But, it utilizes the same size filters as the 6300 design so that replacement filter costs will be low.
If you want a greater level of air cleaning for health purpose, the Blueair 503, plus optional SmokeStop filters, will provide cleaner air in a much shorter amount of time, which makes it an excellent choice for higher-traffic zones with regularly opening doors and windows.
The Conway is plenty suitable for most allergy sufferers who only want to remove allergens from a bedroom, home office, or other comparable areas, but the Blueair is the obvious option for the person with mild chemical allergy or who are bothered by smoke and other odors. It adds a significant ability to remove smells and only rocks at separate particles, all while shooting at sound levels just over a whisper.
The Blueair is a physically large unit, two times the size of the Coway (53 liters) and comparable in size to the IQAir (108 liters versus 109 liters in volume). It's a big, highlight- and dark-gray box, similar in shape to a large home computer, it's twice the size at 20 inches broad by 13 inches deep by 26 inches high.
The Blueair was outdoors a doubt the most energetic particle collector of the ten designs tested. In our initial test at reduced fan speeds, fewer than 9% of the bits visited after 7 minutes of running. That's half the number of particles associated with the next closest design, the Sharp Plasmacluster.
The Blueair filters bits efficiently since it carries bits before cleaning them with a low-pressure-drop polypropylene fiber filter. The charging system uses a logically low voltage to charge pieces outdoors knowing any ozone securely negatively. Blueair states that controlled lab testing confirms that the air density of the filtered air is less than that before purification. The electrostatic charging system and dynamic screen deliver filtration display equivalent to that of a conventional HEPA filter, with an average weight drop. More air can flow through the Blueair's filter at business and quieter fan speeds for the best air filter.
The Blueair is a solid all-around player. It was the first player at particle elimination, and it supplied significant modifications of VOCs too, unlike the cheaper tier designs. In our screening of VOC removal, its voluntary SmokeStop efforts with 4.2 lbs. of triggered charcoal produced the intensity to 32% of the initial energy in the first 15 minutes. The two other high-end devices still reduced more VOCs, though The IQAir (5 pounds.) hit 23%, and the Austin Air dropped to 11%. The IQAir and Austin Air perform this development at a big cost in energy regulation and noisiness. The IQAir will run you a big more in power expenses collectively five years, while the Austin Air needs insert the fan up to aggravatingly full steam to get any better than average particle attracting energy.
