Why Face Masks Can Capture Sub-Micron Particulate

Okay. So there is enough printed material and comments on social media about Masks to choke a very large horse or Blue Whale ( the largest animal on earth ). Does this mean that much of the information is not correct? No. Masks, of various types, styles and materials, have been used for over 100 years to minimize the inhalation of airborne particulate of all sizes. They are used daily in surgery rooms where any form of bacteria or virus can contaminate an open wound and cause serious infections. If, for example, you were wheeled into a surgery room and the Doctors and Nurses were chewing gum and had Twizzlers sticking out of their mouths and not wearing any face coverings, you would be somewhat concerned because they were not wearing MASKS….

Face coverings, masks, gators, face shields, are synonymous with Hospitals, clinics and any type of medical facility where the art of medicine is practiced. Yet, when asked to where a mask to minimize the potential transmission of a highly contagious virus we react with indignation. This virus, Covid-19, is very unique in its ability to enter the body and not show up on very accurate testing on that day. It may be four days later that it responds to the test. This is what makes this virus so sinister. And, it does affect and has killed people of all ages and all walks of life. Not just seniors and those that have underlying medical conditions. Plus, long term affects of getting this virus are still not known. 

Viruses are very tiny and are only captured by very high end HEPA based air filters. The masks are not Hepa filters and even the N90 masks have some limitations. However, there are tiny dust particles in the air that are also trapped in your face covering when you breathe in and these particles can actually assist in minimizing the amount of the virus you inhale. And the quantity of exposure over time is a big deal. So by not wearing a mask you can inhale a large quantity over a short period of time. The mask significantly reduces that high percentage of oral contact. It can be the difference between living or dying.

Science Fair

Being involved with the local High School and Middle School science and engineering students in my area has given me the opportunity to attend and judge a number of Science Fairs. The entrants were both boys and girls and some were in the sixth grade competing with High School students. It is refreshing to see that there is a group of students that enjoy science and technology and the idea of creating something new and taking the time and effort to challenge their knowledge base.

Students also utilize the latest in digital technology to make their science projects state-of-the-art. For example, many of the students I have judged used at iPad or Tablet to tabulate their findings. In many cases these devices were used to take photos or movies of the progress of the science project as part of the conclusion. With all of the now available apps on the market, there is almost nothing one can’t do with a 10″ tablet the correct apps and some ingenuity.

Pure Air Systems has been manufacturing certified, commercial grade HEPA air filtration since 1985. From the beginning PAS looked at their systems designs much like entering a project in a Science Fair. Getting feedback from both commercial and residential customers, Pure Air Systems continually modified and improved its line of HEPA and Carbon based systems to meet or exceed the needs of their customers. In late 1990’s PAS incorporated the then, ECM variable speed motors into all of their systems. This major modification allowed for a motor that operated on 120 volts and 240 volts and 50/60 Hz.  In addition these digitally controlled motors could be programmed to automatically increase speed as the pressure drop across the HEPA filters increased with dirt load.

Having access to the world market also made PAS recognize the value developing a better, more effective and user friendly website. By adding a section called, “Pure Air University,” PAS was able to provide a great primer on the field of filters, HVAC system design, pressure drop, air flow and comparison data to show the efficiency of HEPA versus other type of mechanical and electronic filtration. Educating the customer makes it easier for them to better evaluate their options when it comes to selecting the best filtration systems for their application.

Improving the systems was a project shared by both PAS as well as their suppliers. The new HEPA filers now used in all the systems are scanned HEPA’s rated at 99.99% at 0.3 microns. This is an improvement from the original 99.97% efficiency of the HEPA filters. The small increase actually makes a difference especially in applications where a class 100 or less is required. In addition, better carbon and prefilter materials are used to assist in keeping the HEPA cleaner and removing more of the odors and gaseous pollutants that are often present in conjunction with airborne contaminants.

Hell Opened Up And Put On Sale

Competition can be brutal. Being successful in business requires you to be part mystic, part Samurai warrior, part Bill Gates and sometimes…just plain lucky. The internet, social media, smart phone, tablets, viral marketing, YouTube are now tools that are used by most companies to market their products and services. Sure, the old stand-by’s like the newspaper, TV, radio and mailers are still used but their effectiveness is much harder to measure since you now have analytic’s and metric’s for social media to measure exactly who is getting your information and how they are using it. With ads, TV, radio and mailers it is difficult to know if you are actually reaching your target market.

This ability to utilize social media in has been a real boon to the small, entrepreneurial start-up companies…and this has not gone unnoticed by the big boys. With little or no up front costs, a small company with only a handful of employees can have a presence on the internet that looks as big as a Fortune 500 corporation. And, with the new metrics, analytics and inbound and outbound content processes, these small speedsters can bring a product or service to market, get in infused and become a household name in under six months in some cases.

With that said, there is still the old adage that says, “in the end all that really counts is performance.” You can tout your capabilities and  have a very professional online presence that captures the imagination of your target market. However, if, in the end, you don’t live up to your stated promises, your company will die a very slow and painful death. While the social media crowd can support and push your company and its products and/or services to people around the world in a short period of time. They can also destroy you just as quickly.

Since kids are computer, iPhone, smart phone, tablet, social media savvy before they are 10, their ability to create a company, blog site, website, webinar, or podcast is now a reality. This means companies will be competing with younger and younger entrepreneurs who will be on a par, if not slightly better, then their counter parts in the corporate world. One should seriously take note of this issue.

Pure Air Systems, has been manufacturing high end, commercial grade, certified HEPA air filtration systems since 1985. It has had a presence on the internet since 1994 and has not looked back since. There is no doubt that the ability to promote your product on the web has been a boon to many companies and in many cases is the only way people can find out about their products or services.

PAS has been a performance based company since its inception and today is recognized as one of the leaders in high performance HEPA air filtration. It continues to develop and promote products to meet the needs of an every changing market. The use of their website and social media like Facebook, Twitter and blogging, has truly enhanced their marketing programs and there is no doubt that the sales to international customers has been due in part to social media. But, in the end, the performance of the systems is still tantamount to the success of the company.

Portable HEPA Systems

Portable HEPA units have been around since the early 80’s. The majority of the early versions were round, using a doughnut shaped HEPA filter, wrapped with a prefilter/carbon media to capture the larger particles. The blower/motor was inside the HEPA and pulled the dirty air through the HEPA through slots or holes located  in the outside of the case and the clean air exited through the bottom.

Most of the early versions had three speed motors so you could adjust the volume of air based upon the size of the room or amount of noise you could tolerate. The air volume movement for the units, as measured in CFM, ranged from 50 CFM to 250 CFM. However two major problems occurred with these units. First, any speed setting above the lowest one created enough noise to make you slit your wrists…twice. Second, the rated air flows never approached the stated CFM volumes from the manufacturers. This meant you had to run the system at its lowest setting if you were in the room and then it would take a very long time to clean all the air in that room. But they were the only game in town.

Subsequent portable HEPA units were not much better. Where the original was made from metal and heavy duty plastics, the newer units, mostly imported from overseas, were all plastic. They were just as noisy as the first units but were less expensive and the replacement filters were cheaper. These units used what was called, faux HEPA filters. They were not certified or designed using any of the certified HEPA filter rating systems but they were still called HEPA units. The public had little choice to purchase these if they want HEPA filtration for their indoor environment.

Pure Air Systems was started in 1985 and from the beginning used only commercial grade, certified, metal framed HEPA filters in their systems. Over the years PAS developed a range of larger units using variable speed, digitally controlled motors that could move from 100 CFM to 2000 CFM of HEPA filtered air. And do it rather quietly. These systems were designed to be attached to existing HVAC systems or be used as stand-alone  units.

In 2005 PAS began working on the design for a new portable HEPA unit that would be a commercial grade, powerful and quiet unit with air flow volumes two to three times the levels of the current units on the market. These systems had to be small and light enough to be easily transported and be rugged enough to with stand the abuse of use in commercial and institutional environments. After 16 months of trial and error the HPS 350 and HPS 500 were born. The most powerful and effective true HEPA portable units on the market today.
