Purification Supplies

North Shore Compressor stocks breathing air purification supplies for high-pressure compressor systems used in SCBA and fire service, SCUBA and dive shops, paintball, and industrial breathing air applications. Everything here is the consumable side of your air system — the filtration and media that stand between your compressor and the air your people actually breathe.

Replacement Filter Cartridges

We carry a deep range of X-series replacement purification cartridges, including X152412, X22237, X22240, X22247, X22249, X22511, X22577, X22677, X25670-A, X254351, X256751, X258151, X26242, X274951, X302414, X33677, X34240, X34247, X366722, X49238, X49678, X53248, X542415, X542442, X61797, X65240, X65247, X65248, X65677, X912441, X96337, X96677, XB059183, X-M1501, and X-N-Atl (Nardi Atlantic). If you know your cartridge part number, search it directly — if you don't, call us with your compressor make, model, and serial number and we'll identify the correct cartridge for you.

Bulk Purification Media

For customers who repack their own chambers, we stock activated carbon and molecular sieve by the gallon, plus large and small particulate pads for pre- and post-filtration staging.

Air Quality Monitoring & Testing

Clean air is only verified air. We carry CO-H₂O visual indicators and replacement indicator tabs, humidity element disks, and mail-in air sample test boxes in both single-test and quarterly four-test configurations — the standard way fire departments and dive operations document compliance with Grade E breathing air requirements under CGA G-7.1 and NFPA 1989.

Intake Filtration & Maintenance Kits

Intake filters (X-AI-1 through X-AI-5), Nardi and universal air intake housings, moisture drain and silencer assemblies, and complete maintenance kits for the Nardi Atlantic and Coltri MCH-6 round out the category.

Not Sure What You Need?

Cartridge life depends on your compressor, duty cycle, inlet air conditions, and ambient humidity — there is no single universal replacement interval. If you're unsure what your system takes or how often to change it, call us at 218-226-4695 or request a quote. We service and rebuild these systems every day and can spec the right filtration for your setup, or set you up on a recurring supply schedule so you're never running expired media.
