HEPA H13-H14 are within the highest level of HEPA air filtration and are considered medical grade. Medify MA-112 is by far the best HEPA H13 air purifier with a medical grade filtration system. This device is one of the few brands of air purifiers that use H13 HEPA filters in all its models. It has a very basic 3-stage filtration system, with a medical-grade HEPA H13 filter at its center.
The MERV efficiency rating scale ranges from 1 to 16, where 1 is the lowest efficiency and 16 describes the highest efficiency. This scale addresses particle size range from 0.3 to 10 microns. Filters H10 to H12 are sometimes referred to as True HEPA filters, while H13 and H14 are known as medical grade HEPA filters. These filter 99.95% and 99.995% of all particles down to 0.3 microns, respectively.
In addition to the pre-filter and the important medical grade HEPA H13 filter, the Medify MA-112 has an activated carbon filter. A HEPA filter is a mechanical filter, meaning that airborne particles, such as dust, pollen, mold spores, animal dander, pet hair, etc., are captured on the filter fibers as air passes through. When placed in filtration systems such as purifiers and air purifiers, HEPA filters can remove 99.97 percent of particles from the air. Improved HEPA H13 air purifiers are more difficult to incorporate into an air purifier due to their increased air purification capabilities as a result of smaller HEPA H13 pores. A number of devices use these filters, such as air purifiers, which are designed to remove a large amount of particles and contaminants from the air in your home.
As for coronavirus, air purifiers with HEPA filters are capable of capturing the droplets that the virus travels through (when people cough, talk or breathe). These filters were initially used in nuclear plants, but many new devices use this technology in products that can help clean the air in your home. Let's start with what it means to be a true HEPA filter, how filters are measured and their purpose or use. However, the increased air purification as a result of smaller HEPA H13 pores is well worth the engineering effort and a slightly higher price for consumers. When comparing different air purifiers from different manufacturers, it is essential to consider what grade of HEPA filter is being used.
The pre-filter is specifically designed to capture large particles such as pet dander (which would otherwise overflow the HEPA H13 filter). Keep reading to learn some tips for choosing HEPA filters and how to find the best air purifier for your home. H13 HEPA filters are so comprehensive that they are used in medical environments; hence the name “medical grade”. These filters were first developed as part of the Manhattan Project to protect against biological contaminants.
