Gas & P3 Filters

P3 Filters for respirators offer protection against particles such as dust, smoke and aerosols. They are compatible with our range of respiratory masks and offer a higher protection level and have more effective filtration and can therefore be used to protect against more harmful substances and higher concentrations of contaminants.

P3 Gas Filters

Gas filters for particulates (P3), gas or a combination used on purified and supplied air respirators. All filters comply with EN14387.
