A high-efficiency particulate air (HEPA) filter is a kind of air filter that removes almost 99.97% of particles from the atmosphere down to 0.3 microns in size, as set by the HEPA filter standard. Air purifiers, which filter the air to clean it, often have HEPA air purifier filters. At the same time, there are various kinds of air purifiers, including carbon filters, ionizers, and even non-filter purifiers. Vacuum cleaners and businesses like aerospace, pharma, nuke, and chip manufacturers all employ HEPA filters for the rigorous standards they have to meet for air purity.
The High-Efficiency Particulate Air filter is a mat of thousands of beautiful fibers that can filter out particles. When turned on, an air purifier draws air from space and forces it through a filter, trapping and removing contaminants. According to the standard definition of a HEPA filter, it can capture almost one hundred percent of airborne particles measuring 0.3 microns or below. (Consider that there are 10,000 microns in a centimeter; so, a particle with a diameter of 0.3 microns is very minute.)
The Advantages Of A HEPA Filter
Your investment in a HEPA filter represents the successful completion of testing and approval against a standard. It makes it so the filter can effectively trap even the smallest airborne particles. Indoor air includes several allergens and contaminants, making air filtration much more crucial than most realize. With the right HEPA filter, you can be confident that harmful contaminants are effectively eliminated, dramatically enhancing the air quality in your home.
Why Is It Required To Filter Out Small Particles While Doing Air Quality Control?
Even if you don’t have allergies or asthma, breathing in microscopic airborne particles may be annoying or detrimental to your health. When one breathes, larger particles like pollen, mold spores, dust, and other allergens are filtered out in the throat and nose, which may cause a whole host of unpleasant symptoms in those sensitive to them. A HEPA filter will have little trouble filtering out these bigger particles.
PM 10 particles, with a diameter of only 10 microns, are small enough to pass through the mucous membranes lining the throat and the lungs. Particles as tiny as PM2.5 (with a diameter of 2.5 microns) may penetrate deep into the lungs’ alveoli, where they pose a significant threat to your health. These minute particles mostly contaminate fossil fuels, vehicle exhaust, and chemical production. Around 370,000 premature deaths in 2005 were attributed to European tiny particle pollution.
Airborne particles with a width of 0.3 microns are the most difficult to remove. A HEPA filter is 99.97% efficient in removing particles 0.3 microns in size, and it is even more efficient at removing PM10, PM2.5, and bigger allergens like pollen.
The Most Frequently Cited Benefits Of Using A HEPA Filter
If you’re a new parent, know that a High-Efficiency Particulate Air (HEPA) filter may make your home’s air much healthier for your children and other family members. Experts recommend that smokers use an air purifier with a HEPA and carbon filter. One is to get rid of the actual ash and tar, and another to eliminate the gases and odors that come with the smoke.
Allergen-causing pet dander may be removed from the air using a cleaner equipped with a lifetime HEPA filter. To get rid of both allergies and odors, you should choose a cleaner that has a HEPA filter and a carbon filter.
There are times when a non-filter purifier is preferable to a HEPA filter, such as when you need to eliminate airborne germs and bacteria; a type that operates by incinerating particles will do so with a kill rate of over 99.99%. However, HEPA air purifier filters are more effective and trustworthy. Using them ensures that mold spores, viruses, and bacteria will not continue to multiply unchecked until they are physically eradicated.
