HEPA filters are great for removing larger particles, such as pet dander, pollen, and dust mites, from the air. However, they are not effective at removing mold, VOCs, viruses, bacteria, and particles smaller than 0.3 micrometers. In a study conducted by Consumer Reports, the Molekule Air purifier was tested in Auto (similar to medium) and Silent settings. In Auto, the air purifier reduced particles by 0.3 microns at 18.0% (ambient) and 26.4% (clean).
In Silent, it reduced 0.3 micron particles by 6.5% (ambient) and 7.2% (clean). 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).Using a HEPA filter in your home can help reduce airborne allergens that could worsen allergies. But it is also important to keep other areas of your home clean, such as carpets, bedding and curtains, and countertops and tables. It is also important to eliminate the source of allergens and irritants when possible.
For example, the only effective way to keep tobacco smoke out of your home is to stop smoking. The Blueair Classic 605 air purifier was one of four 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. 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. They are especially good at quickly filtering the most common airborne allergens such as dust and pollen; mold and fungal spores; pet dander; dust mites and their droppings; car soot; and tobacco, marijuana, and wildfire smoke. When choosing an air purifier, look for one with a high CADR (Clean Air Delivery Rate) for tobacco smoke or other pollutants you want to remove from your home. CADR numbers provide the cubic feet per minute of perfectly pure air that a purifier can produce at its maximum configuration. The U.
S. HEPA standard states that most HEPA filters must capture 99.97% of particles in a single pass. The Molekule Air purifier has been redesigned to meet this standard with its entire machine compliant with the HEPA H13 standard - not just the filter - which can capture 99.97 percent of particles that are as small as 0.3 microns. It is important to note that air purifiers are limited in terms of filtering gases and that you should replace filters frequently for optimal functionality - usually about every three months.
