Certified Particle Respirators

Masks for Against Solid & Liquid Particles, Viruses and Bacteria


A multinational team dedicated to the protection of people at high risk of contracting COVID-19 (SARS-CoV2) due to the nature and environment of their work.

Covid Certified Filter 150nano

Quality Label

Most masks, even certified ones, are tested for their capability to filter particles having the “Most Penetrating Particle Size” (MPPS) of 0.3 micrometers (300 nanometers). The German CCF Quality Certification requires testing the filtering raw material -meltblown polypropylene- for penetration at 150nm, a dimension which is very close to very small SARS-CoV2 virus droplet and particle sizes.

The CCF Quality Certification requires the use of strict quality control parameters for raw materials, such that more COVID-19 virus particles/droplets are filtered, the use of specific filtration testing machines that are able to perform detailed measurements, and constant quality monitoring of the raw materials and the products, compared to random tests that most mask manufacturers perform.

As a result, aēramasksTM can be traced back to specific raw materials used, a sign of superior quality control and assurance.

Safety ​

The filtering meltblown polypropylene fabric used in the aēramask ensures more than 99% filtration efficiency, which may reach even 99.9% under certain conditions. Therefore the great majority of particles (including micro-organisms of certain sizes) is filtered by the fabrics.

The high filtration efficiency along with the design of the mask that ensures a tight face-seal result in at least 56% lower Total Inward Leakage (how many particles reach the inside space of the mask and therefore are inhaled).

The very low breathing resistance makes the user breath comfortably, without accumulating respiratory fatigue, without build up of toxic carbon dioxide and sweat inside the mask.


The use of high quality soft fabrics, a soft nasal cushion with adaptable nose clip, comfortable headbands and the innovative chin strap make it easier to put on and position correctly on the face, which enables the aēramask™ to optimally adapt to facial movements and the shape of the face, improving compatibility with glasses and eye protection.

The Challenge

Low Filtration Capability

N95 and KN95 masks are benchmarked to filter only 95% of particles, allowing 5% of the particles to pass through the mask body.

Adulterated and non-certified masks flood the market, bearing no or fake CE certification markings. These masks are not offering high filtration assurance and jeopardize the health of users..

2-8% Inward

The poor design and selection of inferior quality raw materials of most masks marketed, along with the fact that masks with earloops cannot be pulled tight to form a face-seal, due to the hurting force exerted behind the ears, leads to a significant percentage of particles (including infectious viruses) reaching the mouth and nose through gaps that exist due to inadequate sealing.

Imagine holding an umbrella which is full of holes…

Discomfort &

Demand for cheaper masks has led to the use of unqualified filter materials having high breathing resistance. Imagine trying to breath through a pillow-case…

High breathing resistance eventually results in:

  • Respiratory fatigue
  • Build-up and rebreathing of toxic carbon dioxide (CO2)
  • Excessive heat build-up at the area covered by the mask
  • Collapsing of the mask on the face while breathing

These factors severely affect the ability of the user to respirate and perform their tasks.
