When used correctly, air and HVAC filters can help reduce airborne contaminants, including viruses, in a small building or space. 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. With coronavirus cases rising across the country and in many states and cities tightening restrictions, it's more important than ever to stay home and stay safe and sound. Not only do air purifiers make your space more comfortable by spending more time at home, but some experts believe they can help prevent the spread of COVID-19 indoors. While air purifiers have not been specifically tested with the virus, models with a high-efficiency particulate air filter (HEPA) are capable of capturing at least 99.97% of particles as small as 0.3 microns, which is smaller than the size of most airborne pathogens. This could be especially useful if you live with someone who has contracted the virus.
Which Air Purifiers are Best for Protecting Your Home Against COVID-19?But which air purifiers are the best to protect your home against COVID-19? Based on rigorous testing by our experts, these are the five best air purifiers you can buy right now.
1.Winix 5500-2The Winix 5500-2 is the best air purifier we've ever tested. It uses a true HEPA filter, carbon filter and plasma to filter, which are recommended by experts to filter COVID-19 particles. Performed incredibly well in our odor tests, eliminating virtually any trace of cinnamon and smoke. While it's not the most technologically advanced air purifier we tested, it does have a number of useful features such as sleep mode, a timer, and several status lights.
That, combined with a reasonable price, is why it's our favorite model.
2.Blueair Classic 205The Blueair Classic 205 offers basic controls that can be activated via the a, k, a phone. You can start cleaning the air in your home from anywhere. It uses a silent HEPA particulate filter and is particularly good at filtering kitchen odors.
3.Bissell Air220We found that the Bissell Air220 was one of the least intrusive air purifiers we tested a, k, a. It's easy and intuitive to use with a single power button and a fan speed dial with five fan speeds. To eliminate a variety of VOCs, the Air220 uses the recommended HEPA filter, a carbon filter and a pre-filter. Although it wasn't our winner, we still think it's a great option.
4.Coway AP-1512HH MightyThe CADR measures the “volume of filtered air” delivered by an air purifier, with separate scores for tobacco smoke, pollen and dust, according to AHAM, often measured in cubic feet per minute (sometimes in cubic meters per hour). We have published a separate guide for air quality monitors, which we have found are often the best way to better understand the effects of a purifier on air quality, even though they are separate devices that do not directly control the operation of the purifier.
5.Honeywell HPA300For example, the Minimum Efficiency Report Value (MERV) indicates a filter's ability to capture particulate matter. Its three-stage filtration system includes a pre-filter, an activated carbon filter and a HEPA filter.
If pollen or related allergies prevent you from opening windows, operate the air conditioner or forced air cooling system with a clean air filter. Note that some residences may not have any forced air systems, for example, if they rely on hot water or radiant heating systems. If the air quality is poor and you don't have an air purifier, an HVAC filter attached to a box fan is better than nothing. One possible reason the air performed worse than background reduction is that your fan agitated the air and prevented particles from settling. Although Blueair says the last two models are slightly more powerful, they share the same clean air supply rate (CADR) of 120, making them suitable for spaces up to approximately 180 square feet. Portable air purifiers (also known as air purifiers) can be particularly useful when additional ventilation with outdoor air is not possible without compromising indoor comfort (temperature or humidity), or when outdoor air pollution is high. Simply leaving the machine in medium or automatic mode will keep the air clean without having to worry about its settings. This prevents air from bypassing the filter around the edges and ensures that virtually all of the air drawn through the machine leaks HEPA, a design that is likely to contribute to the Mighty's excellent performance. 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. . .
