Compatibility chart

Check this once, never wonder again.

  • Fits one mask: the Tesoro TS-100 full face respirator
  • The thread: 80mm screw fit, hand-tight in seconds, these are the large rounds
  • Not for the rest of the range: the TS-100X takes the 40mm P-A-2, the TS-M101 takes A1-P2 canisters, the TS-AX takes PM2.5 pads
  • Quick self-check: pull a cartridge off your mask. If it's a wide 80mm round, you're on the right page
  • Each set is three parts: carbon cartridge, cotton pre-filter, cover, and they install together
Works with

Everywhere your TS-100 goes, this is what's working inside it:

  • Painting + finishing: spray paint, lacquer, stain, varnish, the carbon takes the vapor load
  • Chemicals: solvents, adhesives, resins, cleaning agents, lab and shop work
  • Outdoors: pesticide and pest-control spraying, agricultural dust
  • Wood + metal: sanding, grinding, welding-area fume, the cotton pre-filter eats the dust so the carbon stays on vapor duty
  • Site work: construction, drywall, concrete, teardown days

That division of labor is the design: cotton catches particles first, carbon stays fresh for what actually poisons you. It's why these last longer than single-layer cartridges.

Included in the Box

  • 4 × P-A-1 carbon cartridges (80mm)

  • 4 × cotton pre-filters (P1 rated)

  • 4 × filter covers

When should I replace my filter?

Replace your filter when breathing feels harder, you notice odor or taste breakthrough, the filter looks damaged, or it has been used for an extended period in a dusty, chemical, or vapor-heavy environment.

Can I buy replacement filters separately?

Yes. TESORO sells replacement filters for each compatible mask, so you can keep your respirator ready without replacing the full mask.

Are TESORO masks reusable?

Yes, TESORO’s core respirator masks are reusable. Filters are replaceable and should be changed based on use, exposure level, and condition.

What is the difference between full-face and half-face respirators?

Full-face respirators cover your eyes, nose, and mouth for broader protection and visibility. Half-face respirators cover the nose and mouth and are useful for many work, DIY, and general protection tasks.

Do I need eye protection too?

For painting, spraying, dust-heavy work, or chemical exposure, eye protection is often important. TESORO’s TS-M101 includes a half-face respirator and goggle set for users who need both respiratory and eye coverage.
