BLS Zer0 series cupped filtering masks, with FFP3 protection, are one of the main products in the BLS range. With or without an Aeolus exhalation valve, with or without carbons and with welded or sliding elastics, the masks in this series protect against dust, mists and fumes.
The new inner support material, in white colour and carefully selected for greater sustainability, allows greater comfort on contact with the face, thanks to its increased lightness. The softness of the new fabric, in fact, makes it more pleasant to the touch and gives the filtering facepiece better adaptability to the face, slightly decreasing its rigidity. The facepiece is therefore more comfortable to wear, even for prolonged periods, while maintaining its filtering capacity intact.
All models in the BLS Zer0 series have been tested for nanoparticle protection.
The EPI4Nano project, promoted by BLS and carried out over the two-year period 2021/2022 by the Itene Research Institute, based in Valencia (ES), had as its main objective the development, optimisation and validation of specific BLS products for effective respiratory protection against these particles, including carbon nanofibres and metal oxides.
Itene's study showed that the filtering materials of the selected BLS devices, including the BLS Zer0 series as filtering facepieces, filter more than 99% of these nanoparticles
- depending on the model and substance selected - and are to date the only ones on the market to have this certification.
The BLS Zer0 series is available in eight different models, which share the same technical features but differ in certain aspects:
Without Eolo exhalation valve, with welded elastics, partial inner gasket and without activated carbon.
With Eolo exhalation valve, welded elastics, partial inner gasket and without activated carbon.
With Eolo exhalation valve, welded elastics, partial inner gasket and activated carbon.
With Eolo exhalation valve, welded elastics, complete inner gasket and without activated carbon.
With Eolo exhalation valve, welded elastics, complete inner gasket and activated carbon.
With Eolo exhalation valve, continuous elastics, complete inner gasket and without activated carbon.

Sapresti definire la differenza tra un rischio e un pericolo? Prima di ricorrere a un dispositivo di protezione delle vie respiratorie, bisogna adottare tutte le misure atte a ridurre al minimo il rischio derivante dall’attività lavorativa. Cosa si intende con rischio? Un rischio corrisponde all'eventualità di subire un danno, connessa a circostanze più […]
Nuove indicazioni per addestramento, scelta e uso degli Apparecchi di Protezione delle Vie Respiratorie (APVR) in Italia Prendiamo in esame l'aggiornamento legislativo in materia di Sicurezza sul Lavoro introdotto dal DL 21 ottobre 2021, n.146, (coordinato con la legge di conversione 17 dicembre 2021, n. 215), recante Misure urgenti in materia economica e fiscale, a […]
Gestione del rischio nella protezione delle vie respiratorie Quando non è possibile eliminare tutti i pericoli di un certo contesto lavorativo, è necessario ridurre al minimo il rischio presente. In che modo? Processo Questa operazione rientra nel cosiddetto processo di "risk management" (gestione del rischio), ovvero il complesso processo finalizzato a identificare, monitorare e […]
