FAQs

  • What is pollution mask and what is it used for?
  • Pollution mask is a common name for filter respirator mask. Filter respirator mask cleans the inhaled air off harmful substances, such as atmospheric aerosols, including smog.
  • What is smog?
  • Smog is an atmospheric phenomenon, formed as a result of fog mixing with smoke and fumes. Chemical compounds, dusts and high moisture making up smog are hazardous for human life.
  • What is sports pollution mask and how does it differ from other masks?
  • During physical strain, our oxygen demand considerably rises. Breath becomes more frequent and deeper. Sports respirator is designed for use during physical strain; therefore, it provides very high breathability and maintains good filtration at the same time.
  • Can a sports pollution mask be used outside sports?
  • Naturally. The BROYX ANTYSMOG SPORT respirators are certified sports masks (CE marking) and are perfect for both leisure and professional applications.
  • Who are the masks intended for?
  • We recommend using the BROYX pollution masks to everyone who is exposed to suspended dusts, including smog. It can be used to protect the respiratory tract during sports, leisure activities and time outdoors when the air quality is reduced or there are natural, but undesirable pollens in the air.
  • What is the difference between the Alfa and Delta models?
  • Both are equipped with identical BROYX 4P1 filter elements, but there is a substantial difference in the mask face-piece design. The face-piece of the BROYX Alfa mask is made of openwork polyester nonwoven fabric, while the BROYX DELTA model’s face-piece is made of neoprene and features a different fastening system. The advantage of the BROYX ALFA model is its high vapour permeability, while the BROYX DELTA mask is flexible, more stable, and provides additional face protection against unfavourable weather conditions.
  • What filter is the mask equipped with?
  • The BROYX pollution masks are equipped with the four-ply BROYX 4P1 filter element. The filter includes the HEPA E12 filtering nonwoven fabric (filtration effectiveness ≥ 99.5%) and a layer of active carbon.
  • How does the mask filter work?
  • Solid particles and liquid droplets are filtered out as the air passes through the consecutive filter layers and the impurities are deposited on the fibres of the filtering layer. It is one of the most effective methods of cleaning the air off aerosol particles. The high effectiveness is thanks to the special filtration layer design – its fibres are electrostatically charged, which causes them to pull particles and droplets suspended in the air and facilitates their deposition on the filter element.
  • What is mask filtration class?
  • Mask filtration class determines filtration effectiveness. In accordance with the EN 149 standard applicable within the EU, there are three classes designated as: FFP1, FFP2 and FFP3. The higher the number, the higher the minimum guaranteed filtration effectiveness (but breathing resistance is larger as well).
  •   Why does the filtering effectiveness of the filter nonwoven fabric not determine the filtering effectiveness of the entire mask?
  • An effective pollution mask must be equipped with a high-quality filtration nonwoven fabric, but it is not enough. The respirator design cannot ensure ideal tight fit on the face. The presence of any types of gaps causes the unfiltered air to be sucked in and drastically reduces the protection level. Therefore, the mask fit and proper filter element design (e.g. exhalation valves, nose-piece) are so important to provide effective protection.
  • Why the BROYX masks are the FFP1 class and not FFP2 or FFP3?
  • The BROYX pollution masks have been designed to provide the good FFP1 protection level with the maximum breathability (that is the minimum air flow resistance). Achieving the FFP2, or even FFP3, protection level is possible, but it would entail much higher breathing resistance, especially when there is a higher oxygen demand caused by physical strain.
  • What are HEPA type filters?
  • It is a group of highly effective filters – from E10 85%+ to U17 99.999995%+. Among the HEPA filter, we can distinguish the EPA, HEPA and ULPA subgroups.
  • What is HEPA filter?
  • It is the H13 or H14 class filter. These filters are very effective in removing air pollution, although at the cost of very high air flow resistance. HEPA filters are used both in industrial laboratories and operating theatres, which require the highest level of air sterility. Unfortunately, due to high air flow resistance, they are not suitable for use in pollution masks. However, they are successfully used in air purification systems, air-conditioners and vacuum cleaners, that is where forced air flow can be used.
  • What is EPA filter?
  • It is the H10, H11 or H12 class filter. These filter types feature slightly lower filtration effectiveness than that of the HEPA filters, but significantly lower air flow resistance with very similar effectiveness. To compare, the EPA H12 effectiveness is 99.5%, while the HEPA H13 – 99.95%. However, air flow resistance in the EPA filters is considerably lower, which translates into much easier breathing and better comfort of use.
  • What is N99 filter?
  • It is a designation used in the USA, where federal law determines the division of filter respirator masks (42 CFR Part 84). This classification does not overlap with the European standards, it is based on other testing methodologies and does not entitle to the EU certification!
  • Why the BROYX VALVE V2 valves are permanently fixed in the BROYX 4P1 filter?
  • For better seal. This type of valve fixing minimises the ingress of unfiltered air between the valve and the filter element. The presence of any types of gaps causes the unfiltered air to be sucked in and drastically reduces the protection level.
  • What is CE?
  • The CE symbol means that the manufacturer declares that the product has been subject to specialist testing and meets the quality and safety standards.
  • Is CE marking obligatory for pollution masks?
  • Yes, this is mandatory certification for all filter masks in all the EU countries. The European Union pays particular attention to the protection of the users of respirators; therefore, certification is complex, and effectiveness verified regularly. Each filter respirator mask constitutes personal protective equipment of the highest, third category.
  • Why CE marking and EN 149 certification are so important?
  • For masks, tests carried out in a certified laboratory in accordance with EN 149 are equivalent to independent use and crash tests for cars. A mask user is not able to assess the mask filtration effectiveness by themselves; this is done for them by a notified laboratory carrying out certification and inspections. Passing a full and complete test in accordance with EN 149 is a step to obtaining the right to mark the filter respirator mask with the CE safety marking.
  • What do mask tests carried out by a notified laboratory involve?
  • These tests check the safety and functional effectiveness, including filtration effectiveness, breathing resistance, mask flammability, air leakage, etc. Besides, checked as part of the certification procedure are manufacturing and quality assurance processes, product labelling and user information.
  • Do masks without CE marking not work?
  • We cannot verify that, as the manufacturer has not performed mandatory tests to prove that. We have no guarantee that their pollution mask works and is safe for the user.
  • What technologies have been used in the BROYX ALFA mask?
  • See the list of technologies below:
    • BROYX 4P1 filters – for effective filtration
    • BROYX VALVE V2 valves – for easier exhalation
    • Face-piece made of polyester = very high breathability and vapour permeability
    • 360° design = the mask is fastened at the back, which allows its precise adjustment
    • Robust, wide hook-and-loop fastening = easy adjustment
    • Reflector at the back part of the mask = higher safety
    • Very low weight = comfort and stability on the head
    • Nose-piece with additional sealing = comfort and seal
  • What technologies have been used in the BROYX DELTA mask?
  • See the list of technologies below:
    • BROYX 4P1 filters – for effective filtration
    • BROYX VALVE V2 valves – for easier exhalation
