Use code MASK-FILTER to get 15% off any filter with purchase of an adapter.

In an effort to bring more functional full face respirators into existence, we've partnered with NOS EXA Group to develop a new gas mask adapter.

These 40mm filter adapters for GOST masks are printed out of hardy, low porosity photo-resin coupled with an O-ring for an reliable airtight seal. This is more than your average hobbyist 3D printed product. Each filter is leak tested and quality controlled.

Why GOST?

Everyone and their mother has some form of Soviet or Eastern Bloc gas mask kicking around, complete with caked on dust, flaking olive paint, and a questionable amount of carcinogens.

However, wearing it without the filter just isn't as cool. So many people just choose to suck it up, and inhale whatever a conscripted Soviet Laborer packed in there 45 years ago. Which is unfortunate, because many of these masks still have a fair bit of utility in them.

With this adapter there is no need to compromise, enabling thousands of masks to be used effectively with modern NATO spec 40mm filters. 

Why masked SLA printing?

For the uninitiated there are two forms of printing, FDM and SLA.
FDM is what most people think of when they think of 3D printing. A strand of material is deposited in layers, much like frosting on a cake. 

SLA is different. UV light cures a photoreactive material in a pool and slowly lifts the shape out. Section by section.

The level of aliasing and detail achieved by SLA exceeds that of FMD. The end result is a smoother, and more structurally dense product This means the part can withstand abuse it will undeniably face. Unlike standard FDM  printed filaments, this photoresin has a low porosity. Making it much more suited for use with respirators.

Installation Manual

Specs

  • Adapter works with most 40mm GOST threaded filter
  • Printed with a Masked Sterolithographic curing process operating at a frequency of 405nm for optimal dimensional accuracy and toughness
  • Utilizes O-ring for airtight seal
  • User serviceable

Replacements, & Returns

If the adapter arrives structurally damaged or defective we will send a replacement free of charge, or issue a full refund. If this is the case, notify support or start your return within seven days of taking delivery.

Health and Safety Reminder

Gas masks are filtration devices.  They are not positive pressure apparatuses and do not produce oxygen.  Such PPE should not be used in the case of gas leaks, chemical spills, or anyplace where simple asphyxiants are in a high concentration.

Filter Adapter

The adapter fits like a glove on the nozzle, so it creates a strong seal and didn't have any issue fitting the filters.
