The HEPA Filter – The Cornerstone of the Austin Air Purifier What is a HEPA filter? Why do they always come up when researching Austin Air Purifiers and Austin Air filters? Well, the history of the HEPA (High-Efficiency Particulate Arresting) is very interesting. A little-known historical fact is that the original HEPA filter was first designed back in the 1940s. The HEPA filter was placed in the Manhattan Project facilities as a way of preventing the spread of airborne radioactive contaminants. By the 1950s, HEPA filters began appearing in commercialized products. In fact, the HEPA filter became synonymous with best-in-class filter performance and high efficiency. It became a high standard and ultimately became a registered trademark. HEPA filters were widely understood to have the capacity to capture a large amount of very small particles above all other Austin Air Purifiers and cleaners. Up to that point in time, many Austin Air Purifiers and cleaners simply recirculated the air of your home. HEPA filters were here to stay, capable of removing at least 99.97% of airborne particles 0.3 micrometers (Âµm) in diameter. To this day, HEPA remains one of the best filtering methods in the industry. Studies have confirmed that the air we breathe in our homes is many times more polluted than the outside air. That is quite alarming, given that outside air is contaminated heavily with vehicle and industrial pollutants, molds, spores, and other contaminate. Cleaning the air in our home with high-quality air filters is not only wise but results in fewer family breathing problems and illnesses. With the right systems, viruses and bacteria that are often the source of respiratory illnesses will be removed. Austin Air HEPA filters are capable of capturing dust, smoke, pollen, dust mites, debris, mold spores, and pet dander. All potentially cause allergies. The Austin Air HEPA filter helps minimize allergies and the resulting uncomfortable symptoms associated with their onset. Once you select your air purification system, make sure you strategically place it where you maximize the air filtering. Also, be diligent in following manufacturer instructions on the replacement intervals of your filter and pre-filter. These elements are the heart of your system. Keeping them clean ensures the effectiveness of any air purification system. A high-quality Austin Air Purifier with an Austin Air HEPA filter delivers the best clean air for you and your family.
