Best Choices for HEPA Purifiers Honeywell True HEPA Whole Room Air Purifier with Allergen Eliminator, HPA 300, Levoit Core 400s, Winix 5500-2, Blueair Blue Pure 211+Medify Air MA-40, BISSELL air320, Rabbit Air MinusA2, Blueair Classic air purifiers. In Auto (similar to medium; the air does not contain a particle counter to adjust to air conditions, but instead asks you to enter the approximate size of your room, after which the machine chooses a fan speed that Molekule deems appropriate), the air performed worse, reducing particles by 0.3 microns at only 18.0% (ambient) and 26.4% (clean). In Silent, it performed even worse, reducing 0.3 micron particles by 6.5% (ambient) and 7.2% (clean). And in Dark plus Auto, 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).
Interestingly, those numbers closely reflect our results in automatic configuration with the PECO system activated, suggesting the possibility that the Molekule Air relies primarily on its physical prefilter, not its patented PECO mechanism, to remove particles. The best air purifier for the bedroom is quiet, has a high CADR rating, a HEPA-based filtration system, etc. All of these qualities are best combined in the Alen BreatheSmart 45i. That makes it the best air purifier for bedrooms.
This portable air purifier is ideal for your desk or small room. Can cover up to 150 square feet of space. The company claims that AirSoap's advanced purification system, which uses a high-energy plasma field to trap and ionize air particles flowing through, can trap and kill even the smallest viruses, up to 14.6 nanometers (most disposable HEPA filters can only filter up to 300 nanometers). And while AirSoap is not marketed as a device that kills COVID, the company says the air purifier is capable of capturing extremely small viruses such as coronaviruses and influenza, which are generally “too small for traditional filters to capture”.
HEPA-type filter: This filter is a lower quality version of a True HEPA filter and does not meet the standards set by the U. The 45i model is the best BreatheSmart unit and it's easy to see which is the best bedroom air purifier. Clean and compact, the Coway air purifier uses a four-stage filtration process to remove 99.98% of particles in the air. The CADR rating is the most important metric that tells us how efficient bedroom air purifiers are at removing 3 of the top air pollutants.
But according to Kevin Shim, director of Coway US (an appliance company known for its air and water purifiers), these standard filters, while certainly effective, are not as efficient as HEPA filters. We like other Blueair products, and this one adds cool air to its purification capabilities: it cycles air five times an hour in a 326 square foot room. One possible reason the Air performed worse than the background reduction is that its fan agitated the air and prevented particles from settling. Second, depending on what the manufacturer determines as “bad enough air quality,” an automatic adjustment can allow the air in your home to be heavily loaded with particles before starting the purifier.
In fact, our years of testing have shown that any properly sized purifier will distribute filtered air evenly to the farthest corner of a room. Knowing that the air purifier will work throughout the night makes air purifier producers design silent units. Nor have we found evidence that the fan function of machines, as Dyson claims, makes them superior to other purifiers in distributing filtered air in a room. .
