Research shows that filtering air can help remove harmful particles from indoor spaces, particularly allergens, smoke and mold. However, air purifiers work best in combination with proper filtration and home cleaning techniques. Before doing so, know that an air purifier is not a panacea. There is very little medical evidence to support that air purifiers directly help improve your health or relieve allergies and respiratory symptoms.
This is partly due to the fact that it is difficult to separate the effects of known air quality pollutants in your home from other environmental and genetic factors. For example, how do furniture and ventilation in your home affect you, in addition to indoor pollutants?) But if you suffer from an allergy or asthma, an air purifier with a HEPA filter may be useful for you, as it will be good at removing fine particles in the air. 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. Air purifiers are designed to remove contaminants from the air. This includes allergens, dust, spores, pollen and more (.
Some purifiers also capture or reduce bacteria, viruses and odors. However, not all units will be able to do so. If you answered yes to the above points, an air purifier is a good option. Air and HVAC filters are designed to filter contaminants or contaminants from the air passing through them.
Air cleaning and filtration can help reduce pollutants in the air, including particles that contain viruses. For filters used in residential air cleaners, MERV ratings range from approximately 7 to 12, and the higher number indicates more effective contaminant capture. In addition, there are other things happening in your home that can affect effectiveness, such as ventilation (windows open or closed) and new particles that constantly emerge, so the air may not be as filtered as the claims lead you to believe. That's not just a financial concern, since air purifiers work best when cleaning a single room, it's worth considering separate machines for, say, the bedroom and living room.
There have been questions as to whether DIY air filters can be effective in reducing virus particles indoors. Many manufacturers use the Clean Air Supply Rate (CADR) rating system to evaluate air cleaner performance. It's best to opt for an air cleaner that uses a fibrous media air cleaner or an electric air cleaner. Some filters are reusable and washable, but require meticulous maintenance, so they are not normally found in the most effective air purifiers.
According to the Environmental Protection Agency (EPA), a portable air purifier is one of the most effective ways to improve indoor air quality in an individual room or area. If you have specific concerns about VOCs, the HM400 is by far the best portable air purifier we've found. 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. Do-It-Yourself (DIY) air filters are indoor air filters that can be assembled from box fans and square HVAC (or oven) filters.
The Winix 5500-2 is a direct competitor to the Coway AP-1512HH Mighty, having a nearly identical clean air delivery rate (CADR) and offering 5.1 air changes per hour (ACH) in a 350 square foot space. Purifiers work best in an adjoining space; if you want to clean the air in both the living room and bedroom, for example, it's best to buy a purifier for each room or move a single purifier with you. 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. .
