Ideal in situations where you already have and use oblong filters on oblong organic vapor cartridges, but have applications where the vapor cartridge is not required, but particulate filtering is.
The 3M™ Filter Adapter 603 enables the 5N11 and 5P71 oblong filters to be directly attached to a 3M Full or Half Facepiece with bayonet fittings.
The filter adapter 603 may be used multiple times.
It provides a cost-effective filtering solution when multiple filters are needed for 3M facepieces.
• Note - the 603 adapter attaches to the facepiece and holds the filter; a 501 Filter Retainer is required to secure the filter in place; see Related Products, below
• Can be used multiple times
• Analysis indicates the 603/5N11/501 break-even price point, compared to using the round 2071 filters, is if you are going to use more than 7 oblong filters by themselves, for particulate filtering alone
• Sold as a pair
