Introduction
The Pocket Smoke Mask (PSM) is a small, portable heat resistant hood that covers the entire head. It provides effective barrier for your eyes, nose, and mouth from lethal smoke and fumes during fire hazards. The PSM’s ionized filter blocks the harmful particles in the heavy smoke and allows you to breathe while making your way to safety during emergency situations.
How It Work
The Pocket Smoke Mask (PSM) filter contains a circulating counter washing layer which is designed for repeated filtering within the effective time span. Toxic particles from the fire have no chance of getting into your mask during your escape.
The PSM filter is made of multi-element Activated Charcoal Cloth. Activated Charcoal is one of the best anti-smoke materials approved by the industrialized countries of the contemporary world. Activated Charcoal has a significant smoke absorbing and toxic particle removing capacity, thus is able to maintain breathable air supply to the user in smoky environment.
The Oxidized Fiber Fabric layer provides the filter with high temperature isolation function which enables the filter package to remain effective in environment up to 450°C.
The filter package includes not just one, but two layers of Activated Carbon Fiber filter. Using high temperature sealing technique, the Activated Carbon Fiber filters are manufactured to form dense pore structures with a large surface areas and a much higher absorption efficiency that that of a regular activated carbon.
With the doubly secured design from its two BET: 1300 filters, even the most tiny smoke particle will be prevented from entering the interior of the mask.
PSM can function without any problem under a moderate smoky Condition. PSM has shown the appreciable effects against:
| Carbon Dioxide | CO2 |
| Hydrogen Cyanide | HCN |
| Hydrogen Chloride | HCI |
| Hydrogen Sulphide | H2S |
| Carbon Tetrachloride | CCI4 |
| Acrolein | CH2=CHCHO or C3H8O |
| Formaldehyde | HCHO or CH2O |
| Hydroxylammonium compound | NH3OH |
| Ammonia | NH3 |
Features
PSM is a small and portable smoke mask which takes up much less space than other similar short-term respiratory filters. You can carry PSM with you to anywhere to protect yourself at all times.
The flexible elastic rubber strap is designed for all users. It can fit all adults (even when wearing glasses, with beard and long hair all together), children and infants.
As easy as ABC, simply don the PSM over your head. No training required.
PSM provides a 360° full angled vision. A wide and clear vision is often one of the most important safety factors when evacuating from hazardous environments.
The active carbon filter system does not require a mouth piece to be attached to the user’s mouth. Hence, you can still give and receive clear and important instructions to/ from others when escaping from danger.
Our simple design prevents you from wasting important escape time to assemble the smoke mask. The one piece design also minimize chance of parts (such as rubber bands) lost or destroyed during emergencies.
20 minutes of respiratory protection is more than enough time to escape from danger in most urban surroundings. 20 minutes of respiratory protection can dramatically increase your chances of survival when your escape route is blocked by toxic gases.
PSM is a heat resistant hood that covers the entire head. It can effectively protect the vital organs such as the eyes, nose, and mouth from lethal smoke, dust and fumes during your escape to safety.
How to use
Tear off the top of the packaging and remove the packaging from the mask. Unfold the mask and rubber neck strap.
Place your palms together, slide them into the rubber hole, and put outwards with force. Don the mask from the hole you pulled until your whole head is inside the Mask.
The rubber neck strap will secure around your neck. Make sure the strap tightly fastens your neck and the filter is in front of your mouth.
- Pocket Smoke Mask (PSM) is not a self contained breathing apparatus. It can filter toxic smoke but cannot supply extra oxygen. Escape from the fire and smoke immediately after putting the mask on.
- Under no circumstances should the user attempt to use the PSM as a fire fighting equipment.
- PSM and its components are high temperature resistance but not fireproof.
- The efficiency of PSM against all types of contaminants cannot be pre-determined. It is therefore important to leave the danger area as quickly as possible.
- PSM is built for emergency escape purposes, not for firefighting.
- If PSM is exposed for more than 20 minutes, it is no longer efficient.
- PSM is vacuum packed to protect and ensure optimum efficiency of the PSM filter. The efficacy of the PSM filter diminishes when exposed to the atmosphere.
- The 7-layered filter system are filtering a limited Carbon Monoxide only.
- In no circumstances shall HKMASK be liable for any consequences or damages arising from the use of the PSM.
- Product information provided herein is based on tests performed in specific conditions which may differ from the user’s operating environment.
- HKMASK is not liable for any damage, loss, injury or death resulting from the use of this product.

The chemical agents are added to the mixing chamber as a liquid using syringe pump. The gas is first vaporized and mixed with 30℃, 70% R.H. 30L./min clear air. Then this mixed gas flows into the test box. In this test, Multi-gas Monitor Type 1302, Brael & Kjaer, Denmark (non-disperse IR) is used to monitor the concentration of the gas.
The minimum breakthrough time is intended only for laboratory tests under standardized conditions. It does not give an indication of the possible service time in practical use. Possible service times can differ from the breakthrough times determined according to this standard in both directions positive or negative depending on the conditions of use.
PSM is not a self contained breathing apparatus. It can filter toxic smoke but cannot supply extra oxygen. The 7-layered filter system are filtering a limited Carbon Monoxide only. Escape from the fire and smoke immediately after putting the mask on.
