Sigma OF-02 CBRN Filter
The Sigma OF-02 CBRN Filter is a high-performance combined respiratory protection filter designed to provide broad protection against a wide range of organic and inorganic gases, acid gases, vapors, toxic substances, particles and biological hazards. The A2B2E2K2SXP3 filter class combines gas and vapor filtration with high-efficiency particulate protection, making it suitable for demanding military, emergency response and industrial applications.
The filter is designed to capture industrial and military chemical agents, including highly toxic substances such as phosgene, hydrogen cyanide, cyanogen chloride, sarin and mustard gas. Its special plastic housing is designed and certified to provide protection against mustard gas penetration.
The integrated P3 particulate filter provides a filtration efficiency of at least 99.995% against dust, aerosols, bacteria and viruses. The filter can also be connected to a filtration system with auxiliary ventilation for applications where assisted airflow is required.

Care
Gear Care (Read This Before You Wreck It)
Always follow the manufacturer’s care instructions first. That’s the rule.
In general:
Soft goods (clothing, slings, pouches, etc.) are usually machine-washable at 30°C and air dry only — unless the label or product page says otherwise. No tumble dryer, no bleach, no “it’ll probably be fine.”
Hard goods (plates, helmets, tools, lights, etc.) should not be thrown in a washer. Wipe them down with water or a mild cleaner and let them dry naturally. No solvents, no high heat, no dishwasher experiments.
If you use cleaning methods that are not recommended by the manufacturer and something fails because of that, it’s not covered by warranty.
Treat your kit like it’s going back out tomorrow.

Shipping & Returns
We move fast.
For in-stock items, handling time is 0–1 business days and we hand your order to the carrier right away. Shipping speed and price depend on what you pick at checkout (Posti for standard/economy in Finland & EU, FedEx for faster domestic, EU/EEA, and international delivery).
If something is shown as out of stock but still purchasable, that means it’s on back-order / special-order. Estimated dispatch for those items is usually 5–30 days. High-end products like night vision devices and thermal optics are most often “made to order,” meaning we source them individually per customer request.
If your cart has both in-stock gear and made-to-order gear, we may ship what’s ready first so you don’t have to wait.
You’ll get a tracking code as soon as your parcel is handed to Posti or FedEx.
