Particle filter swiss air with pre-filter (Set of 20)

Highly efficient particle filter as the heart of the Swiss Air TH3 / TM3 with long service life for ‘loose fit’ (close-fitting) fabric half masks and tight fit (close-fitting) silicone half masks. The supplied replaceable pre-filter significantly extends the service life of the particle filter. Please ensure that the seal protector is removed before insertion and that the lubricating layer remains on the seal (do not remove the lubricant). Filters are available individually (see variant 4088.402) or in a set of 20 pieces (see variant 4088.432).
