Coway AP-1512HH Mighty is an effective, efficient and affordable air purifier that is a finalist. Coway Airmega 200M has a different look but the same great performance. In Auto mode, the air performed worse, reducing particles by 0.3 microns at only 18.0% (ambient) and 26.4% (clean). In Silent mode, it performed even worse, reducing 0.3 micron particles by 6.5% (ambient) and 7.2% (clean).
In Dark plus Auto mode, with its primary PECO purification system turned off and its fan at the equivalent of a medium setting, it reduced them by 21.3% (ambient) and 18.0% (clean). The Blueair Classic 605 is one of four air purifiers tested by Consumer Reports for an “Excellent” rating on both the highest and lowest speed settings. It uses the brand's HepaSilent technology, which can filter 99.97 percent of particles down to 0.1 microns. Air purifiers are designed to filter essentially any unwanted particles in the air, such as dust, pollen and smoke.
Some models even claim that they help protect against the coronavirus COVID-19 by filtering airborne particles that carry the virus. By filtering the air, air purifiers promote a healthier breathing environment, reducing allergy and asthma symptoms. With charcoal filters, these appliances are also natural deodorants, making them ideal in the kitchen or bedroom. After testing 10 models, both in the laboratory and at home, we believe that the Blueair Blue Pure 211+ Auto is the ultimate air purifier, combining quality, efficiency and value in one elegant package.
It surprised us with how effectively it cleaned the air in a room, without being annoying. If you buy on a budget and need an air purifier for a small space, then the BlueAir Blue Pure 411 Auto is unbeatable with its automatic mode, perfect for children's room or office. It's easy to set up and its operation is also quiet, making it ideal for nighttime use. The Honeywell HPA300 is a bulky device that offers good value for money considering its impressive performance.
It's a large oval air purifier with slats around it, which makes it look like it belongs in the office of a dystopian future. It's also quite heavy, weighing 17 pounds, so this is the type of air purifier you won't want to move once you put it in. A truly powerful device, the HPA300 ranked second in the CADR test with its three filters capable of removing most contaminants in a large 465-square-foot room. With an average CADR score of 306, it performed slightly better on dust than on pollen and smoke.
Replacement filters are very reasonably priced and only need to be changed every 12 months. The most expensive and heaviest air purifier we tested is also one of the best air purifiers - Blueair Health Protect 7470i. It can clean a room of contaminants efficiently, increasing its resistance relatively easily when needed. With two lights in the front representing gas pollutants and larger particles respectively, Blueair Health Protect 7470i has the clearest indicator of air quality we've seen on any of the devices.
Every time we started cooking, those lights would turn bright red and the fan would go into overdrive. The weight of this air purifier makes it a bit cumbersome when trying to move it to different rooms but it's the only device we tested that includes a pair of wheels to help with this. Even though it's the quietest of the bunch, it's also worth mentioning that it tends to consume more energy than other devices at 0.241 kWh in 24 hours so all that data comes at a cost. The recommended room size for this model is slightly smaller than its sibling - Blueair Blue Pure 211+ Auto - but it still performs well in a fairly large living space of approximately 418 square feet with an average CADR score of 275 performing better on pollen compared to dust and smoke.
If you want a quality air purifier and you don't mind the high price then we recommend Blueair Health Protect 7470i as it's an ideal purchase if you want to see the impact your air purifier is having in real time.
