The new BLS Zer0 Flat filtering face piece, which is also available with the High Efficiency Aeolus® Valve, features a flat three-flap design that allows it to adapt perfectly to all facial movements, ensuring maximum protection and efficiency at all times. The folded bottom flap allows easy opening of the face piece without contaminating the inside.
The device, equipped with a rigid inner core, which provides it with sturdiness and high breathability while maintaining low breathing resistance, is available in two sizes: M/L and S to perfectly fit all face types.
The inner nose clip, placed between the layers of filter material, adapts optimally to the contours of the nose and eyes, guaranteeing very good visibility and maximum compatibility with spectacles.
The elastics are made of durable, high-performance textile material. The addition of a backing layer allows the elastics to adhere to the filter body without the use of exposed metal parts.
The Armor outer protective layer surrounding the filter material protects it from dirt, dust and liquids, as well as from the stress caused by prolonged use. The device performs for a longer period of time.
BLS Zer0 Flat filtering face pieces are packaged in sealed individual bags, to ensure maximum hygiene and make them easy to carry with you, as well as to make them particularly suitable for placement in vending machines.
BLS Zer0 Flat filtering masks allow 99% filtration of nanoparticles. The filter material also has a water vapour transmission ratio (amount of vapour able to pass through it) of 3380 g/m². This value is much higher than that of the vast majority of our competitors. Tests performed according to ASTM E96/E96M.
Agenti biologici e trasmissibilità Alcune vie di trasmissione infettano con maggiore probabilità di altre. In generale, se ne possono individuare tre macro-categorie: la trasmissione diretta, la tramissione indiretta e la tramissione da vettori. TRASMISSIONE DIRETTA Trasmissione per ingestione Può trattarsi di ingestione accidentale tramite aerosol o droplet ad esempio. Per droplet si intende […]
Which are the different types of facemasks and what are the differences? Alongside so-called surgical masks, there are also FFP1, FFP2 and FFP3 masks, with and without valves. What are the differences between these three types of protective facemasks?Surgical masks are medical devices that are used to protect ourselves and others. In fact, they block the propagation of droplets emitted orally when coughing and sneezing, or simply speaking. Nevertheless, they do not guarantee the blocking of the virus dispersed in aerosols as they are not leak-proof on the user’s face and do not have a filtering function during inhalation.
Nanoparticelle: cosa sono e perché sono così pericolose Le nanoparticelle sono uno dei principali rischi industriali emergenti. Le nanoparticelle sono generalmente identificate come particelle formate da aggregati atomici o molecolari con un diametro compreso indicativamente fra 1 e 100 nm. A volte il termine è utilizzato per indicare il particolato ultrafine (in particolare le […]
