Gas masks with 40mm thread for the filter canisters that are compatible with N.A.T.O. standards are a must-have for your personal preparedness during the Coronavirus (COVID 19) worldwide outbreak. Even if the coronavirus headline numbers drop within the next few weeks, the problem will not go away until our communities develop heard immunity.  Heard immunity, as stated by Bill Gates during a TED talk interview on March 25, 2020 (please watch the video below), is when communities reach between 50% to 90% infection rate and therefore these communities will develop a high proportion of immunity.  These key target percentages are very far off, so please know that the Coronavirus problem is here to stay for at least 18 months, at best; and here to stay forever, at worst.  Not to mention, any other novel virus that develops and spreads before that because of how interconnected our countries and communities are.

You might believe that buying a gas mask is not practical because there are other solutions that are less bulky or more economical.  These two points had validity before the worldwide Coronavirus outbreak, but now, the supply chain has ceased to function under the just-in-time business model.  The "just-in-time" model was developed to reduce inventory costs by using real-time data to receive inventory within 3 days of selling it.  Again, it's genius when applied in a perfect world.  The just-in-time model doesn't factor in risk variables and leaves the public vulnerable and dependent on institutions and government entities.  

A failed Just-in-Time model has left us with worldwide N95 respirator shortages and manufacturers delaying shipments.  N95 masks were manufactured with the intent of being a disposable product.  They were made to be discarded after one use.  That isn't the case anymore.  The United States has run out of N95 respirators.  For example: the Memorial Hermann Medical System in Houston, Texas is reprocessing N95 masks by taking the masks through a process that takes hours and hours to disinfect them with a process called Hydrogen Peroxide Vapor Sterilization in a machine named Bioquell.

An N95 Mask Pre-Coronavirus price was $1.50 USD.  Keep in mind, the coronavirus has led governments to suspend all elective surgeries to make hospital beds available for the growing number of COVID 19 patients.  That means that many hospital workers have been re-assigned from their regular and great paying jobs to duties that support the fight against the Coronavirus by reprocessing and therefore disinfecting N95 masks.  It's a genius idea, but not the highest and best use of money or hospital professional's time.  The solution is to switch from N95 masks to gas masks that use disposable filter canisters that were intended to be re-used.  Reprocessing the N95 masks up to 15 times (some institutions are reprocessing them up to 50 times before discarding the N95 masks) raises the true price of these, once $1.50 disposable products, to over $1,000 each.  There have been many masks that have had to be thrown away because of hospital professionals wearing make-up, adding to the inefficiency of re-using disposable N95 masks.

Being dependent on these imports is not the best idea, either.  China is not shipping N95 respirators to the United States as fast as before.  The shipments for most essential medical products from China is being intentionally withheld and delayed as proven in the following article published by the Seattle Times on April 11, 2020 (

So, here we have it folks.....  The idea of buying a gas mask used to be considered crazy.  It now seems like the most practical idea because of the shortage of N95 respirator masks.  If delays weren't enough to convince you, then the lack of resupply should persuade you to become more self sufficient and less dependent on others for your supplies.
