Airinum Frequently Asked Questions

1. Where and when would you wear the mask?

There are several good reasons, all are protective to the wearer:

  • To protect from air pollution and smog which is responsible for 1 in 9 deaths worldwide according to the WHO. Microscopic air particulates and dust can cause lung irritation and chronic lung conditions
  • To protect from disease toxins, such as fungus spores, bacteria & viruses carried in mist droplets particularly when moving around in crowded urban environments, when traveling
  • To minimize breathing in pollen & allergen if you suffer seasonal allergies

2. What are the advantages of the Airinum mask compared to other types of masks?

  • Airinum is designed for comfort and fit. Fit is the most important measure of a mask’s effectiveness. A better fit keeps the mask on and keeps you from touching your face.
  •  Airinum comes in 4 sizes, with adjustable ear loops, and an adjustable head strap, ergonomically designed to for all face shapes and sized to fit children and adults.
  • Airinum has exhale one-way valves for improved airflow and clearance of moisture, without sacrificing the quality of intake, making the mask suitable for wearing when exercising.
  • A memory foam over the nose minimizes air leakage and keeps glasses from fogging.
  • The filters in the Airinum are KN95 certified, the gold standard for protective masks, and filters more than 95% of particles down to 0.3 um (1 micrometer = 1/1,000,000 meter) The key to protection is in the mask’s filter and the fit of the mask. The filter is easy to replace and lasts for about 100 hours.
  • Airinum filters are a 5-layer patented system of 2 outer layers of breathable polypropylene, with an inside active carbon layer to reduce odors, and 2 electro-charged layers to filter micro pollutants, bacteria and allergen, for use up to 100 hours.

3. What is the difference between KN95 and N95?

KN95 is the Chinese certification standard, N95 the US standard.

The Federal Drug Administration and Centers for Disease Control have both approved the use of KN95 masks in the cases of N95 shortages, but appearances aside, there are two major differences between the masks: First, the American-manufactured N95 masks can withstand a slightly stronger pressure as the person wearing it inhales and exhales, according to infectious diseases specialist Dr. Michael Rajni “Fit is of maximal importance,” Rajnik told the Herald, but said KN95s were “adequately equipped” for doctors and physicians if they are produced by legitimate medical manufacturers like 3M. KN95 is the Chinese standard, N95 the US. Also, the KN95 mask are designed to fit differently than the N95s.
