302DCN carbon cartridge
P-A-1 organic vapour grade with coconut-shell activated carbon.
Product family 05
The consumable half of the system: organic vapour cartridges, KN95 particulate cotton and the spare valves and gaskets that keep a facepiece sealing.

Cartridges, pads and spares are where repeat orders come from. All of them are our own parts, made to fit our own bodies.
What we actually make on this line, and what a buyer can specify.
P-A-1 organic vapour grade with coconut-shell activated carbon.
Particulate layer at 95% or better, stacked over the cartridge.
Covers, rings and gaskets that hold the media flat against the port.
Cartridges ship in sealed pairs; volumes and pack sizes are quoted per order.
| Your problem | Fit this | Replace when |
|---|---|---|
| Dust only | Particulate filter pads | Breathing gets harder or the pad is loaded |
| Paint, adhesive, solvent smell | Carbon cartridges | You first taste or smell the product through the facepiece |
| Both at once | Cartridge plus pad stacked | Whichever limit is reached first |
| Leaks, fogging, stretched straps | Maintenance kit | Any part that has hardened, split or lost elasticity |
Replacement
For the smells that dust masks do not stop.

Ten KN95-class pads for reusable facepieces.
Replacement
The small parts that decide whether a facepiece keeps working.
No. Our cartridge mounts are specific to our facepieces. We do not claim cross-brand compatibility.
It depends on concentration and breathing rate. For odorous products, replace at breakthrough — the moment you can smell it inside the facepiece.
We manufacture rather than trade, so private label, pack configuration and volume pricing all run through the same production line.
