The BLS 400 series is a versatile and reliable solution for respiratory protection in professional environments. Thanks to the universal RD40 connection, the wide range of filters available and compatibility with various devices, these filters offer effective protection against a wide range of contaminants.
BLS 400 filters are equipped with a standard RD40 threaded connection conforming to EN 148-1, making them compatible with many respiratory protective devices on the market. This standardisation ensures that the filters can be used with different masks, offering flexibility and ease of use.
The BLS 400 series offers a variety of filters for different protection needs:
This variety allows users to select the most suitable filter for their specific operational needs, ensuring maximum safety at all times.
European standards EN 143 and EN 14387:2004+A1:2008 define protection against dust, gases and vapours by assigning specific identification colours to different types of contaminants. For example, filters for organic gases (type A) are marked brown, while those for inorganic gases (type B) are grey. This colour coding facilitates quick identification of the appropriate filter for each situation.
BLS 400 series filters are classified as Class 2, providing the highest level of protection against high concentrations of contaminants. This classification makes them particularly suitable for high-risk professional environments, where a reliable barrier against dust, gases and vapours is required. Choosing a Class 2 filter ensures not only safety, but also compliance with the most stringent standards for respiratory protection.
BLS 400 series filters are designed for use with the following BLS full and half masks:
However, it is important to note that some filters weighing more than 300 grams may not be suitable for use with half-masks, as they may compromise comfort and fit. In such cases, use with full masks is recommended to ensure optimal performance.

With a filtering capacity of more than 94% for FFP2 and more than 99% for FFP3, the new BLS 502 and BLS 503 masks are DPI without valves, CE certified according to European regulation 2016/425 and technical standard EN 149: 2001, able to protect users in the event of exposure to solid and/or liquid non-volatile particles (dust, fumes, mists) and to block the dispersion of viruses both incoming and outgoing. They are, in fact, sealed on the face and manufactured with a "welding” process, without seams and perforations on the fabric from which micro particles could pass, thus creating a barrier during exhaling, protecting the environment from the user of the mask. These masks are therefore ideal for use in the food & beverage and medical sectors, as well as in all work environments where contamination by the user must be avoided.
