MD-1 Children's Gas Mask - Full-Face Protective Respirator for CBRN Defense
The MD-1® Kids Gas Mask is one of the only reusable, professional-grade CBRN full-face respirators specifically engineered for children . It is built to the same protective principles as adult gas masks, while being scaled for reduced weight, optimized airflow, and improved comfort for pediatric users.
Unlike disposable hoods or single-use escape masks, the MD-1® uses standard 40 mm NATO threaded filters , allowing families and preparedness planners to maintain a single unified filter system across adult and child masks. A detachable filter hose further reduces facial weight by allowing the filter to be carried on the body rather than directly on the mask.
When paired with appropriate filters, the MD-1® is designed for protection against chemical, biological, radiological, and nuclear airborne hazards , provided oxygen levels are adequate.
"A prudent person foresees danger ahead and takes precautions. The simpleton goes blindly on and suffers the consequences. - Proverbs 27:12"
Child-specific airflow and geometry
Designed to reduce breathing resistance and fatigue compared to adult masks.
Detachable filter hose system
Allows the filter to be worn in a pouch, minimizing weight on a child’s face and neck.
Panoramic polycarbonate visor
Provides wide situational awareness with greater than 70% field of view.
Oro-nasal inner mask
Reduces fogging and limits CO₂ buildup during extended wear.
Articulating 5-point mesh head harness
Distributes pressure evenly for a secure, comfortable fit across a range of head sizes.
40 mm NATO filter compatibility
Works with the same filters used by adult MIRA Safety gas masks.
PAPR compatible
Can be paired with powered air-purifying respirators to reduce breathing effort and improve endurance.
Select the correct mask size based on the child’s age and facial structure.
Conduct a negative pressure seal check before use.
Attach a compatible 40 mm NATO filter or approved PAPR system.
If using the extension hose, carry the filter in a pouch to reduce facial load.
Supervise the child at all times while the mask is worn.

CBRN RESPIRATORY PROTECTION
Professional-grade protection without the gatekeeping. CBRN gas masks for civilians since 2018.
MIRA Safety was founded by Roman Zrazhevskiy and Tanya Mironova in 2018 — born out of Roman's own experiences with 9/11 and Hurricane Sandy and the realization that civilians had effectively no access to military-grade respiratory protection. Their flagship CM-6M gas mask launched in 2018 (and was later featured in Christopher Nolan's TENET). The company partners with European defense contractors to bring CBRN-rated masks, filters, and protective equipment to professionals, preppers, and families — including a full line of children's protective equipment. Their philosophy: "When crisis strikes, you can't rely on anyone but yourself."

Answers, straight up.
Product-specific questions on the left. Shopping with SRO on the right. Both open-ended — hit us if we missed one.
Can this mask use the same filters as adult gas masks?
Yes. The MD-1® uses standard 40 mm NATO threaded filters.
Is this mask reusable?
Yes. With proper storage and maintenance, the MD-1® is designed for repeated use.
Is this safe for very young children?
Only children who can pass a basic breathing capability test should use a negative-pressure gas mask. See safety notes below.
How long does shipping take?
Most orders process within 1–3 business days from our warehouse. From there: 5–7 business days economy, 2–3 business days expedited, or overnight if you need it fast. Free economy shipping on orders over $150 (contiguous US). Alaska, Hawaii, and Pro Eagle / freight items are quoted at checkout. You’ll get a tracking number and link the moment your order ships.
What’s your return policy?
30 days from the day your order arrives. Gear has to come back unused, with all original tags, stickers, and packaging intact. For standard items we’ll send a prepaid return label and deduct return shipping from your refund. Oversized or freight returns are on you, unless the item showed up damaged, defective, or wrong — in which case we cover it.
Refunds hit your original payment method within 10 business days of approval.
What can’t I return?
Final-sale items, gift cards, food and drink products, personal-care items, anything customized or engraved, briefs (hygiene), and hazardous materials. If you’re not sure whether something qualifies, email us before you order — we’ll tell you straight.
Do you ship outside the contiguous US?
Yes. Alaska, Hawaii, and US territories ship on freight-quoted rates calculated after checkout. International orders are available worldwide at variable rates; duties and import fees are the customer’s responsibility. EU customers get a 14-day cancellation window per EU consumer law, on top of our standard return policy.

Email info@stayreadyoutdoors.com within 7 days of delivery with your order number and clear photos of the damage (product + packaging). We’ll replace, refund, or ship a return label on us — no back-and-forth. Damaged, defective, or wrong-item claims never cost you shipping.
Can I talk to a human before buying?
Yes. Email info@stayreadyoutdoors.com — we answer every message ourselves, usually within a few hours during business days. We carry this gear, we use this gear, and we’d rather talk you out of a kit that doesn’t fit your mission than sell you the wrong one.
