It is one of the three Coway models that are part of our ranking. The AP-1512HH is designed for rooms 361 square feet or smaller. 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 depends mainly on its physical prefilter, not its patented PECO mechanism, to remove particles. This Levoit air purifier is a Good Housekeeping seal holder, thanks to its combination of value, performance and intelligent design. In particular, the unit's three-stage filtration, which includes a true HEPA filter, helps capture even the smallest airborne contaminants in rooms up to approximately 400 square feet.
A built-in precision laser sensor accurately monitors particles in the room and automatically adjusts fan speeds as needed. The purifier is also incredibly quiet, it works at only 24 dB, which you will appreciate if it is placed in your bedroom. One of our staff evaluators has been operating the unit for several months at home and says that the light hum is quite quiet at night. Then there are intelligent capabilities, including the Levoit app, which allows you to monitor air quality in real time, view filter life, and set schedules.
Overall, the Blueair Pure 211+ is a simple air purifier with fantastic performance. It has a one-button design to turn the device on and off, and toggle between power options. If you just want excellent purification performance, Pure 211+ is an excellent choice. HEPA stands for high-efficiency particulate air and refers to the fact that HEPA filters allow air to pass through with little resistance while quickly capturing almost all of the particles that the air carries.
In fact, our years of testing have shown that any properly sized purifier will distribute filtered air evenly, in the farthest corner of a room. In its Boost configuration, when it was moving the maximum amount of air, the air could reduce 0.3 micron particles by 61.3% under ambient starting conditions and 57.0% under clean starting conditions. The Levoit LV-H132 removes particles from the air with its three-stage filtration system that includes a pre-filter, a true HEPA filter and an activated carbon filter. These can remove 99.97 percent of air pollutants 0.3 microns in size, which basically means they're really effective at removing most indoor air pollutants.
It circulates room air more than four times in an hour and is equipped with a built-in smart filter, replacement reminder and night light. Okay, if you have the money and want a super-powered air purifier, or if you prefer a purifier to cover your entire house than buy one for each room, the Coway Airmega 400 could be the best air purifier for you. The Air Purifier 6 performed very well, as you would expect from a machine with a clean air supply rate (CADR) of 325 cubic feet per minute. The Levoit H132 may not have all the details of a smart air purifier, but its affordability and compact size make it the ideal beginner's indoor air purifier that works well in small to medium sized rooms.
There's no reason for someone to buy a different brand if they want to get the best purification available, which is the point of buying an air purifier; otherwise, simply vacuuming every day and several times a day, it's roughly the equivalent of most air purifiers on the market. 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. Air purifiers are designed to eliminate indoor air pollution from cooking, car emissions, dust and fire, among other things. .
