I was curious as to how long a gas mask would last. How long is the filter going to last before it needs replacement, roughly? When exposed to a nerve agent the standard MOP4 gear used by the US Army starts to break down in four hours; the filters however last longer. In combat it is advised to change your filters once per week; at least that is what they told us in training while I was in the Army. Some gas masks have a connection for you to drink water, but only officers and infantry are usually given those masks.
That means the gas mask will last until you need to drink some water and the inside of the protective gear, under all that activated charcoal is a very warm place to be. Filters are pretty good, but dusty conditions like those in Iraq will shorten their life drastically. Basically the activated charcoal layer absorbs the particles in the air and you have to inhale a little harder to pull the air through that filter.
As you get more particles in the filter you need to work harder to breathe. At some point it will become better to change the filter rather than keep going. Of course changing the how to do a coyote swap in the middle of a gas contaminated area is not advised. The efficiency of the gas mask depends on the type of gas and the amount of exposure.
Fire fighters usually only carry a 20 minute air reserve and work in sealed environments to avoid inhaling smoke; their masks provide total protection. But, if the gas is saran then that won't matter; saran has to be inhaled. However, if the gas is phosgene Cl2CO then it can burn through the filter. If you are a tanker then you hook your air supply into the tank's own air supply and it uses over pressure to keep gas contamination out.
In that case you have access to a better set of filters. When working with a disease like Ebola the only mask required is a simple cloth face mask which will last until it is exposed, because Ebola is a blood born illness. If the gas is a blister agent like mustard gas then you need total coverage, any area exposed will be burned and blistered. If the gas is Saran then you only need a gas mask, but the surgeon's gas mask is not enough.With flu season upon us, many people are wondering what precautions they can take to prevent transmission of the H1N1 swine flu virus.
Frequent hand washing is definitely helpful, but what about protective gear, such as gloves and masks? Do masks and respirators really protect against H1N1? Before rushing out to buy either, take a moment to read the information below.
Unlike facemasks, respirators form a tight seal to the face. They are primarily manufactured for use in construction and industrial jobs that expose workers to dust and small airborne particles.
Best Designer N95 Mask
CDC guidelines do not suggest respirators for children or people with facial hair. A study conducted by Dr. In contrast, the N95 respirator blocked nearly all respiratory particles. By the time studies are done to find out how effective respirators really are, flu season is likely to be over. Given this information, how can you best protect yourself and your loved ones? The U. Department of Health and Human Services HHS recommends a comprehensive flu prevention strategy to reduce your risk of infection.
This includes:. These preventive strategies will greatly reduce your risk of H1N1. An ounce of prevention this flu season can help you and your loved ones stay happy, healthy, and symptom-free. Looking to find your closest flu clinic? If you do not have one available, cough or sneeze into your elbow instead of your hand. Your elbow does not touch as many things door handles, keyboards, telephones or people as your hand does! Wash your hands often with soap and warm water for at least seconds or use an alcohol-based cleaner Avoid close contact with people who are sick If you become ill, stay home until you are symptom-free for at least 24 hours  These preventive strategies will greatly reduce your risk of H1N1.

Lindsley WG.Bought a czech m10 gas mask that came with 2 filters to put on each cheek. Cyanogen Chloride will deteriorate your filters in about 30 minutes. They don't don't bother to tell the average soldier that though. Isn't ignorance bliss. The scout has a point. Were the filters sealed in an airtight bag before you put them in the mask?
Anyway it depends on the usage. I know a guy who bought this mask for his air soft tourneys to filter out smoke grenades they used and he said it was just fine for a couple of years. And, well they are active once you put them out of the bag, although minimally.
They are using active coal as a sorbent, so as long as some air passes through, they will deplete albeit very slowly. The type of agent your exposed to could compromise your filter depending on the stuff in variations of time example viral agent vs Nerve Gas Honestly the type of gas mask as well as its filtration design makes all the diference. Standard field issue with the m93 Nato Filters will likely have the 16 hours to as little as a few minute duration. If you get a high end battery powered positive airflow system type deal it could potentially last months depending on the agent.
It is diffficult to answer expiration questions because it is a imprecise question to begin with. I believe a filter could last easily 15 years if stored correctly in its original packaging out of excessive heat and cold, but if its left out of its packaging it could last as little as 5 years or less.
Gas mask filters should be kept in their packaging to preserve their life which should be. New canisters are rated for 8 hours if from the sealed container. If you are not using it for CS gas or something like that it will work much longer than that but the 8 hours is for effectiveness against nerve agent type or poisonous gasses.
If they are not in a sealed container ie original packaging then they are likely already bad. To use them could be extremely hazardous to your health. Answer Save. EODbot Lv 6.

I actually got this from EJ last Christmas. I wanted it for my allergic rhinitis. I heard that this helps alleviate allergies. It just so happened that we the Philippines had that Taal volcano Ashfall concern to deal with after, and now this, Corona virus. Then it has a HEPA filter that eliminates smoke, household dust, mold, pollen and other fine particles up to 0. I hope so. It fits snuggly also on the sides.
At the same time though, because of its design, you can breathe comfortably. The design protrudes in the middle so you have space to breathe. You can also change the filters every week. I forgot to buy the filters from them although it came with two filtersso I just place the PM 2.

Since it's a fairly common question, and "it depends" is such an unsatisfactory answer, we thought we'd explain it here in a bit more detail.
The useful life of filters and cartridges is not fixed. Once the filters have successfully blocked a large amount of particulate matter, they still won't let that material into your lungs. They do however start allowing less air to past through, and breathing will become more and more difficult. You may not notice it at first, but as the filters clog up, it will become harder to suck in a breath. Trust us, you'll notice eventually. That's when you know it's time to replace the filters.
As we mentioned, the 3M pancake filters also have a thin layer of charcoal pressed inside. The charcoal is there to absorb smells and odors.
It works like a sponge. And like a sponge, there is a limit to how much it can hold. Once the filters have soaked up all the organic vapors they can, you will start to taste or smell the offending item through your mask. Once you start to smell the things you are trying to block out, it is time to change your filter. Only you can tell if it is becoming difficult to draw a breath, or if smelly vapors are making their way through your mask. Now that you are aware of the capabilities and limitations of these filters, you'll recognize the signs that it is time for replacement.
A little more about the 3M filters: They are different than the standard filters in that they have a layer of charcoal bonded in the middle. The filters come standard on the Lead and Asbestos Respirator Combo so they can keep out the really nasty dust such as lead and asbestos.
However the filters also serves to eliminate lower levels of organic vapors that you may smell from solvents or household bleach. The filters come standard in our mold remediation kit designed specifically for removing mold from houses and other structures. This kit features the full face mask to protect the mucous membrane of the eyes from mold spores.
Looking for a reliable respirator?A gas mask is a mask used to protect the wearer from inhaling airborne pollutants and toxic gases. The mask forms a sealed cover over the nose and mouth, but may also cover the eyes and other vulnerable soft tissues of the face. Most gas masks are also respiratorsthough the word gas mask is often used to refer to military equipment such as a field protective mask.
The gas mask only protects the user from digesting, inhaling and contact through the eyes many agents affect through eye contact. Most combined gas mask filters will last around 8 hours in a nuclear biological chemical NBC situation. Chemical specific filters can last up to 20 hours in an NBC situation. Airborne toxic materials may be gaseous for example, mustard gas and chlorine gas or particulates such as biological agents. Many gas masks include protection from both types.
Gas masks are used in construction to protect against welding fumes, in demolition to protect against asbestos or other hazardous particles, and in the chemical industry when handling hazardous materialsas in making repairs to leaking equipment or cleaning up after spills; workers are usually issued gas masks as a precaution against leaks.
During demonstrations and protests where tear gas or CS gas is employed by riot police, gas masks are commonly used by police and demonstrators alike. Aside from serving their functional purposes, gas masks are also used as emblems in industrial musicwith the most notable example, the subgenre of drum and bass called neurofunk. These emblems are used by graffiti taggers because the mask protects them from the paint canister's toxic fumesand by urban explorers venturing into environments where hazardous materials, such as asbestos, may be present.
The traditional gas mask style with two small circular eye windows originated when the only suitable material for these eye windows was glass or acrylic ; as glass is notoriously brittle, glass eye windows had to be kept small and thick. Later, the discovery of polycarbonate allowed for gas masks to have a panoramic lens although the gas mask did not see this implemented until a long time after polycarbonate began to be used for gas mask lenses. Polycarbonate meant that lenses could be larger and so enabled a larger field of view.
Some have one or two filters screwed via inlets onto to the gas mask while others have a large filter coffee can filter connected to the gas mask with a hose that is sometimes confused with an air-supplied respirator in which an alternate supply of fresh air oxygen tanks is delivered.
Absorption is the process of being drawn into a usually larger body or substrate, and adsorption is the process of deposition upon a surface. This can be used to remove both particulate and gaseous hazards.
Although some form of reaction may take place, it is not necessary; the method may work by attractive charges. For example, if the target particles are positively charged, a negatively charged substrate may be used.
Examples of substrates include activated carbonand zeolites. This effect can be very simple and highly effective, for example using a damp cloth to cover the mouth and nose while escaping a fire. While this method can be effective at trapping particulates produced by combustion, it does not filter out harmful gases which may be toxic or which displace the oxygen required for survival.
Gas masks have a limited useful lifespan that is related to the absorbent capacity of the filter. Once the filter has been saturated with hazardous chemicals, it ceases to provide protection and the user may be injured. Most gas masks use sealing caps over the air intake and are stored in vacuum sealed bags to prevent the filter from degrading before use, but the protective abilities also degrade as the filter ages or if it is exposed to moisture and heat.
Very old unused gas mask filters from World War II may not be effective at all in protecting the user, and can even potentially cause harm to the user due to long-term changes in the filter chemical composition.
World War II gas masks contained chrysotile asbestos or crocidolite asbestos in their filters. Breathing blue asbestos in the factories resulted in the death of 10 percent of the workforce due to pleural and peritoneal mesothelioma.
This rate was between 2. Many stories have originated from various Russian gas masks and their filters that are now common in surplus stores; the GP-5 was often considered to have an asbestos filter.With dangerous air quality from the devastating Camp Fire near Chico forcing hundreds of schools to cancel class, hundreds of thousands of parents to scramble for child care, and our lungs to scramble for air, it may be time to actually pay attention to what the numbers and codes on those dust masks really mean.
Anyone who has worked with drywall, removed paint, or crawled into an attic has probably strapped on one of these cheap white masks. You guessed it. It blocks percent of particulates well, N is required for lead and asbestos, but it would certainly be good for smoke. And if you see a "P"? It filters exactly the same stuff — the only difference is, it also filters out oil-based aerosols if you were working with chemicals. A P or N are both equal in terms of filtering out soot.
Get caught up on the fire fight here. So if you trust the rating system, you may not need to pay more. But the more expensive masks may have better straps and better seals and reinforcement. Some masks are even made for smaller faces, like this one. Men with beards cannot get the full benefit of a mask, and many men have looked at shaving it off for the sake of their lungs.
Protective systems recommend a half-face mask or full-face mask if you really want to save your beard, but also filter your air. If you thought people in face masks looked funny when folks first started wearing them, this is a whole other level of awkward, but who knows. Face masks look pretty normal now, so maybe this will too.
They say they make it harder to breathe since you have to suck air through all those layers of material.
