What is a HEPA Filter, and Why is it So Important?
During the hot summer months, you often hear more about outdoor air quality - especially in areas that have higher levels of pollution and smog in the air. In their recent State of the Air 2014 report, the Heart and Lung Association found that 147.6 million Americans live in areas where particle pollution or smog are at levels that make breathing the outdoor air dangerous. When the air outside is dangerous, you need to focus on providing cleaner, healthier air quality inside your home. One of the most efficient ways of doing so is to use whole house HEPA filters.
What is a HEPA Filter?
HEPA stands for High Efficiency Particulate Air. Originally introduced and developed during WW2 as a "top secret" method to protect against biological, radiological, and chemical warfare, these filters are designed to filter the air you breathe to reduce the number of allergens and pollutants. There are two different categories for HEPA filters that determine their effectiveness at removing harmful pollutants:
- True HEPA - True HEPA filters go through a testing and certification process to make sure that they provide a 99.97% filtering efficiency for removing pollutants and allergens in the air.
- HEPA Type - HEPA type filters do not go through a testing process to prove their efficiency. These filters are typically cheaper than True HEPA filters, and only remove around 85-90% of the allergens that pass through them.
Why are HEPA Filters so Important?
Did you know that the air in your home is considered to be one of top five health risks in the environment by the Heart and Lung Association? Your indoor air is filled with dust, pet dander, molds, bacteria, cigarette smoke, dust mites, and other particles. These particles pose significant health risks, including:
- Increased Allergies
- Higher Risk of Asthma Attacks
- Breathing Problems
- Heart Disease
- Respiratory Diseases
HEPA filters are designed to trap pollutants as small as .3 microns, which are considerably smaller than the particles that your nose and throat can actually filter. If these tiny pollutants are not filtered out of the air in your home, they end up deep in your lungs, where they can cause significant damage and health risks.
While proper cleaning can help to lessen the amount of these pollutants and the health risks associated with them, it cannot get rid of them completely. Additionally, the poor quality outdoor air also enters your home as well, which can make these issues even worse. This is why HEPA filters are so important.
Whole house HEPA filters remove the allergens and harmful particles in your home's air, creating a much healthier indoor environment for you and your family. If you want to make sure that the air you breathe inside is as clean as possible, a whole house HEPA filtration system is the best option.
