Still Confused About True HEPA And HEPA Type Air Purifiers? Our Review Will Help You Know The Difference And Make Informed Decision
We tend to think of air pollution as something that happens outside—but that is not always the case. Even inside your home, there are things like dust mites and dirt trodden in from outdoors to worry about. Indoor air pollution from sources like this can irritate your lungs and contribute to allergies and asthma. If you have asthma or another breathing difficulty, then you would need one.
They use HEPA filters which capture about 99.97% of airborne particles up to 0.3 microns.

Why You Should Trust Us
People are now turning to natural solutions for health issues such as allergies and asthma, and the easiest way to remove these airborne contaminants is by using an air purification system. However, we admit that picking the right one for your house can seem like a daunting task especially when you do not know where to start.
We picked our top 5 air purifiers based on the following features:
Feature #01. The HEPA Filtration Specification
The HEPA filtration specification consists of two numbers that designate a very high level of filtration of very fine particles. The first number represents the filtration efficiency as a percentage and the second number is the particle size retained. For HEPA, filtration efficiency must be 99.97% and particles retained must be as small as 0.3 micrometers (formerly microns).
To give you some idea of how small these fine particles are, a human hair is approximately 100 microns thick. HEPA filtration is designed to capture 99.97% of particles one-third of one micron in size. HEPA filtration is an important and valuable feature to have as part of your air purifier.
Feature #02. HEPA Filter Certification Standards
The best HEPA filters are certified to meet stringent standards, such as the European Norm 1822 (also referred to as EN 1822) for filtration performance, and are identified with a certification number. Certified HEPA filters are also known as True or Absolute HEPA filters. European companies often refer to them as S-Class filters.
Originally developed for rating filtration systems for maintaining extremely clean environments in the pharmaceutical, computer manufacturing, medical and other clean-critical facilities, certification using this standard assures you that the filter will perform as a true HEPA filter.
The Two-Part Test
The EN 1822 is a two-part test. The first part of the test identifies the particle size that most easily penetrates the HEPA filter, to establish the “Most Penetrating Particle Size” or MPPS.
Once the MPPS is determined, the second part of the test challenges the filter ONLY with particles of the most penetrating size. If a filter can maintain 99.97% filtration under the very worst-case scenario, then you have a filter that delivers true HEPA filtration.
