This 4-pack includes four factory-sealed Israeli Civil Defense 40mm gas mask filters for compatible masks, hoods and powered-air systems. It is intended for larger households, multiple respirators or buyers building a sealed replacement-filter supply.
Each filter uses the standardized EN 148-1 / Rd40 threaded interface. Check the packaging, canister condition, intended hazard and complete-system instructions before use; 40mm thread compatibility alone does not define filtration performance.
Compatible with all gas masks and PAPR hoods using a standard 40mm threaded port marked EN 148-1, Rd40, or STANAG 4155 - including every mask and PAPR system sold on CBRNmasks.com. Not compatible with bayonet-style or proprietary quick-connect respirators without an adapter. Always verify the type of your mask connection before ordering.
A gas mask or PAPR hood is only as good as the filter inside it. The 4-pack gives every family member a fresh sealed filter and leaves spares in reserve - the most complete filter supply option for serious preparedness. Browse our Israeli CBRN Full-Face Gas Masks and CBRN PAPR Hood Systems collections to complete your setup.
Also available as a single filter, 2-pack, and 3-pack.
Free worldwide shipping. 30-day returns accepted.

Schöne Ware, schnelle Lieferung, gerne mal wieder.
This listing includes four factory-sealed 40mm threaded filters. Check the quantity and package condition when the order arrives.
No. They fit compatible respirators with a true EN 148-1 / Rd40 40mm threaded port. Bayonet, proprietary, and other connectors may require a manufacturer-approved adapter or may not be compatible.
Keep them unopened in their original packaging in a cool, dry place away from sunlight, chemicals, and physical damage. Follow the marked expiration and storage instructions.
Service life depends on the exact hazard, concentration, humidity, airflow, and conditions. Follow the filter documentation; do not treat unopened shelf life as a universal operating time.
Replace it when required by its instructions, after relevant exposure, when damaged or expired, or when safe service life cannot be established. Do not rely on smell or taste as a warning.
Check every canister and sealed package for dents, corrosion, punctures, broken seals, or other damage. Keep the shipping packaging and contact us before use if anything is unexpected.

Everything I expected was in the box. I checked the threads, visor and straps, then did a short fit test at home. Everything was fine.
Factory seal intact, canister clean, no marks. Exactly what I wanted for storage.
Works for me.
Would order again.
Packed it with my camera gear and practiced putting it on quickly. After a couple of tries, the sequence felt natural.

The mask seems well made, but I am still struggling to get the rear straps comfortable around the back of my head. I am keeping it, although the fit has not fully convinced me yet.
Would order again.
