Science Is Our DNA

SInce man first walked on the earth he has been finding ways to make life easier, safer and more productive. His inate drive to explore and learn are bult into his DNA. It is a survival of the fitest condition. Everything we use and have at our disposal was invented by man ( or woman ). The balance is deliverd by Mother Nature, which is, in many ways, more powerful and more important. . Some of those things Mother Nature delivers include diseases that are benign to animals but cause significant challenges to man. In some cases man’s own drive creates the conditions by which these diseases become deadly. 

Covid-19 is science. It is biological science and it plays with our DNA. As a virus it follows the same drive as man..survival of the fitest. It will do whatever it takes to keep growing and moving as it jumps from human host to human host.It really doesn’t have a conscience or any political aspirations and is not threatened by any medicine was currently have at our disposal. It will command our attention for a very long time. It is a variant of science so obviously it will require science to tame it. Man has the ability to resolve this issue if it is taken seriously. If not, then perhaps we should paraphrase the words in Matthew 5 where he says ‘ and the meek shall inherit the earth.”

Pure Air Systems has been making HEPA based air filtration systems since 1985 and is now working around the clock to supply a wide variety of medical and commercial operations with HEPA filtration systems to help deal with the Covid-19 pandemic.

Un Masking Covid -19 Size Does Matter

Wearing a mask during the current pandemic has been accepted by and also rejected by large portions of the US population.Some of reasons are political, some are irrational and some are based on science. The latter being the more logical rationale.

It seems that the, “What you don’t see won’t hurt you”, mindset has taken over our ability to feel threatened by the virus. Yet, this virus like all airborne viruses has no concience or cares little about your ability to see it. You can only see particle sizes down to about 20 microns with the naked eye and this virus is about 0.005 microns in size which makes it only visible using an electron microscope. When someone who has Covid-19 talks, coughs, sings or laughs they are expelling millions of sub-micron particles into the air, some as droplets some as fine, invisible mist. The closer you are to that individual and the longer you stay in close proximity to that individual the larger the concentration of the virus you will breathe in. Unless of course you are wearing a mask.

The use of any covering over your mouth and nose is by far much safer than wearing nothing at all. Maks will prevent you from getting high concentrations and also minimize the amount of the virus you may transmit if you are infected. It is, in essence, the human thing to do.Covid -19 will continue to be with us for a long time just like the other Covid viruses for which many of us get inoculated each Fall to reduce our chances of getting the Flu. And, like the Flu this virus is always changing and the longer it stays around the more virulent it becomes and the less exposure you will need to become ill.

Using HEPA Fan Powered Systems For Virus Protection

Keeping employees and customers safe in buildings, stores and other enclosed spaces will be a major part of returning to the new normal. Aside from making desks and work spaces at least 6 feet apart the ability to maintain some form of control over the ventilation systems would be the next major hurdle. The standard HAVC system in residential and commercial building is designed to move the air through return air and supply air ductwork and keep the room cool or warm. The types of filters normally used in these systems are what we call “general duty” air filters. Meaning they will remove large particles, dust and some smoke, but are not really capable of removing anything close to the size of viruese which are down to .005 microns in size. Basically a billionth of an inch.

Pure Air Systems has been making fan powered, commercial grade, HEPA air filtration systems since 1985 and has seven different configurations and air volume sizes to meet most needs in the commercial, institutional and industrial markets. Since its inception, PAS has provided a unique adaptation of their systems so they can be used in a partial by-pass configuration. This allows the HEPA systems to be connected to the main return air duct in a partial-connection taking a portion of the return air and putting in through a 3-stage filter system including a prefilter, carbon media pack and a scanned 99.99% HEPA filter. Using this concept allows for partical cleaning of the air continuously without affecting the performance of the main air handler. In most cases all the air in the room would be filtered once every 30 minutes to an hour. In addition, it is possible to add small amounts of outside air into and through the PAS unit prior to entering the main air handler which helps to pressurize the room area and also dilute the inside air. The small amount of air that is added from the outside does not really affect the temperature since the percentage is usually around 3% to 5 % of the total volume of air being cooled and or heated.

The systems offered by Pure Air Systems range in CFM volume from 50 CFM to 2,000 CFM. These systems all use variable speed motors and are digitially controlled. They are made from components all made in the USA and assembled in Indianapolis, IN.

Covid-19 A Different Type of Media

THE MEDIA is getting a lot of attention these days and depending upon which side of the aisle you sit your position about this pandemic is dependent upon which media outlet you watch or listen to. The term “media” also refers to the type of filter materials used in air and liquid filtration. In the case of these types of materials, they are not subject to opinions or bias. Filter medias have a specific protocol they must pass in order to have a rating for a certain efficiency of particulate removal of certain sized particles.

Pure AIr Systems, founded in 1985, has been making fan powered HEPA based air filtration systems for the commerical, medical, industrial and institutional markets with a very high degree of success. The HEPA media used in their systems is tested under very stringent test protocol to meet or exceed 99.99% removal of particulate 0.3 microns in lager and approach 95% on particulate smaller than 0.3 microns. 

The efficiency of this type of media doesn’t care where the particles came from or how they were generated or even the color and texture. It is a filtration media that is used globally and recognized as the best available filtration for removal of airborne bacterial and viruses. It is important to listen to the science not the hype.

Covid-19 HEPA Masks

The Corona Virus pandemic has brought out a cry for protective gear, masks, respirators and ventilators not to mention HEPA based air filtration systems to maintain positive pressure rooms in make-shift hospitals. HEPA filters are made from special paper-like materials that are extremely dense and designed to capture a very high percentage ( usually 99.99% or greater ) of sub-micron particulate. These filters are used in surgery suites, laboratories, chip manufacturing, and any place where airborne particles ( bacteria and viruses ) are present. 

With the Covid-19 pandemic there is a race to provide any type of mask for the first responders, medical personnel and now the general public. This demand has brought out a number of individuals and groups making masks ( or printing them ) out of various materials; mostly cloth of some kind. However, some are offering HEPA masks that look like a regular cloth type mask. True HEPA masks worn by first responders are PAPR masks. Positive Air Pressure Respirators.These masks have true HEPA filters in their design and also have fans to assist in pulling the air through the HEPA filters. These masks are battery powered. Without the assistance of the fan you would would have difficulty pulling air through the mask with your own lungs as the HEPA paper has extreme resistance compared to standard surgical masks. 

The N-95 masks are similar to MERV 8 air filters. They are good for 95% of particles in the 3.0 to 10.0 micron range. Certainly much better than cloth but not as good as HEPA media. The reason this is important is that viruses, such as the Covid-19 virus, can be as small as .0005 microns in size. As a comparison, your hair is about 100 microns in diameter. This sub-micron size makes Covid-19 airborne and allows it to pass through standard mask materials. This is why this virus is so deadly.

HEPA Filtration For Asthmatics

Asthmatics suffer from airborne allergens more often than people with just normal allergies to pollen, ragweed, animal dander, etc. For many asthmatics a small level of dust or airborne particulate can trigger an asthma attack and the only relief comes in the form of an inhaler or other quick acting medication. 

Allergy sufferers can take a number of over the counter medications to help relieve symptoms especially the runny nose, irritated eyes and general stuffed head feeling that are very typical. Being in an environment where they amount of allergens can be reduced will significantly help reduce or eliminate the typical reactions associated with allergy sufferers. 

Pure Air Systems has been making HEPA based, fan powered air filtration systems since 1985. For over 39 years people around the U.S and overseas have been able to use these high performance air filtration systems from general duty air particulate removal to surgical suite operations and everything in between.  The ability to use these systems with standard forced air ducted heating/cooling systems has enabled thousands of allergy sufferers to have almost complete relief when they are in their homes or offices. The HEPA filters are commercial grade and certified at 99.99% at 0.3 microns and larger. The three stage filtration system also includes a dual layer ring panel filter and carbon media filter for odors and gases.

For asthmatics, the PAS line of HEPA systems has proved to be one of the few HEPA based air filtration systems that can both  reduce the levels of airborne particulate while also pressurizing an entire house, office area or large room. This highly effective system has shown to significantly reduce the need for or use of inhalers for the area being actively filtered. Pure Air Systems also makes portable units that can handle an individual room or small area. These are perfect for a child’s or adult’s bedroom or small house or condo.

Air Filters For Residential HVAC Systems

In today’s fast paced society we often don’t think about common products or processes. We assume that anything we buy or use will operate as indicated and that we should be able to utilize the product with a minimum of effort and retraining. Our home heating/cooling system fits into that category. We turn on the heating or cooling cycle from our thermostat and expect the temperature in the home to match the temperature setting. We do this without much thought. 

When the heating or cooling doesn’t cool or heat adequately we automatically contact our local HVAC contractor rather than even attempt to diagnose the problem by ourselves. While the problem maybe a major malfunction of a component, often times the reason for the lack of cooling or heat is a plugged air filter. 

The blower/motor assembly on your HVAC system is rated at a certain motor horsepower and air flow, as measured in CFM. These are matched systems for the cooling coil and heating system based upon the size of the home. This includes the static pressure the fan sees to pull and push the air throughout the duct system. If the filter is plugged it will take more energy to pull the air through the filter and since the motor/blower assembly is designed to handle a limited amount of static pressure for the CFM it moves. 

If the static pressure capability for the blower/motor is 1.5 ” at rated CFM capacity and the plugged filter adds another .5 to 1.0″ of static load ( which it can do ) it will significantly reduce the air flow through the system as much as 50%. That means it takes much longer to heat or cool your home and it also puts a strain on your system in total. And, it will significantly reduce the ability to remove humidity from the home. Checking the condition of your air filter on a regular basis should be part of your routine.

Pure Air Systems makes a complete line of fan powered HEPA based air filtration systems. We can help you choose the right filter or filtration system for your home to ensure you always have your HVAC system working at its full capacity and that the air in your home is always well filtered.

Pure Air Systems HEPA Filtration System Rescues California Home During Fires

As everyone knows, being around smoke from a forest fire is extremely difficult and dangerous as smoke inhalation can be deadly. For California this past year, the forest fires have been nothing short of horrific. Many homes were lost and smoke hung in the air for weeks in many areas of California.

Pure Air Systems, an Indiana based company, has been making fan powered, HEPA based air filtration systems since 1985. Their systems are capable of being used either in conjunction with an existing HVAC system or as stand alone units. The partial by-pass configuration of the units allow for complete filtration of the home environment while also adding the ability to introduce outside, filtered fresh air to pressurize the home.

A homeowner in the San Francisco area purchased a PAS Model 600HS HEPA Plus system to do just that. His ability to bring in outside air through the 600HS unit and pressurize his home allowed him to stay inside and almost eliminate any smoke or odor from coming into his home. In fact, many of his neighbors also came to his house to escape from the smoke that was everywhere in the SF Bay area.

The 600HS unit has three filters. A dual layer ring panel filter to capture large particles and keep the HEPA clean, a 10 lb carbon filter to remove odors and a scanned 99.99% commercial grade HEPA filter to remove sub micron particulate. Pure Air Systems also makes larger versions of this filtration system ranging from 50 CFM to 2,000 CFM. These systems have been on the market for over 34 years and are the best performing HEPA based air filtration systems on the market today.

Pure Air Systems Moves Into 34th Year Of Selling HEPA Air Filtration Systems

In 1985, Don Musilli founded a company to sell high end HEPA air filtration systems to the residential market. HEPA filtration at that time was somewhat limited to the micro-chip manufacturing industry, asbestos abatement companies, medical operations and some industrial applications. The residential market was using standard pleated, card board box framed general duty filtration media filters or electronic air cleaners. These air filters were located either in the main return air grills or at the point where all the return air entered the main air handler ( HVAC unit ) and were designed primarily to remove very large airborne particles and to keep the cooling coils and fan blades clean.They did little to remove the smaller, respirable sized particulate that could create health issues for many homeowners.

Whether we are indoors or outside, we are breathing air that contains various sizes of particulate. The larger particles. those that you can see with the naked eye, are usually 20 microns in size of larger. ( for comparison, your hair is 100 microns in diameter ). These larger particles are aspirated into our lungs and the majority of them are exhaled out. The smaller, sub-micron particles however, ( those less than 20 microns in size ) tend to stay logged in the lung linings and mucus membranes. These smaller particles may represent a wide range of organic and inorganic materials including pollen, pet dander, ragweed, bacteria, viruses and industrial pollution. For those individuals that suffer from allergies many of these airborne particulate are the primary cause of their respiratory dysfunctions.

Pure Air Systems pioneered the use of HEPA filtration systems with their first model 600H unit.that included a true, scanned HEPA filter rated at 99.99% removal of all particles 0.3 microns and larger, a wire framed ring panel prefilter ( to keep the HEPA clean ) and a true carbon filter to remove odors and gases. These systems were designed to attach to the return air side of a ducted HVAC system using the partial by-pass concept. This unique concept allowed homeowners, for the first time, to use a true HEPA filter system on a residential HVAC unit. These HEPA systems cleane all the air in the house up to 24 times a day and remove a very large percentage of the sub-micron, airborne particulate. 

Thirty Four years later, PAS has added 6 more HEPA, fan powered, air filtration systems to its stable and over 10,000 of these units have been installed in homes and offices across the U.S. and Canada.

How To Identify True HEPA Filters

The term HEPA means High Performance Particulate Absolute or Air. This type of filter is used in many applications where the reduction and/or removal of fine, sub-micron airborne particles is required at a much higher efficiency than standard media filters like the ones used in air handling systems or HVAC systems. In order to qualify as a true, certified HEPA filter it must pass be able to have a rating equivalent to a MERV 17 or higher. This means the filter can capture 99.97% of all particles 0.3 microns or larger. Compare this to a MERV 5 or 6 filter which has an efficiency of less than 20% on particles larger than 10 microns in size.

A true HEPA filter is normally a pleated media filter with large pleats with separators or a mini-pleat with glue type separators and is enclosed in a metal housing.and is sealed with an industrial sealant. The metal housing has a gasket on one end of the housing which is normally placed on knife edge seal to eliminate any air bypassing the HEPA filter. The HEPA paper or filter media is fairly fragile and it also enclosed in a housing to protect the HEPA. 

Because HEPA filter paper is very dense, the ability to pull air through the HEPA requires a larger motor/blower assembly as the pressure drop or resistance as measured in inches of water is much higher than the resistance through a standard throw-away furnace filter.Usually HEPA filters are mated with a blower/motor that is designed for this type of media, or they are enclosed is a housing like the ones Pure Air Systems makes that are stand-alone units with their own blower/motor and prefilters.

Pure Air Systems, located in Indianapolis, Indiana is one of a few companies in the U.S. that makes a high performance, certified HEPA, fan powered air filtration system that can be use in the residential, commercial, institutional, industrial and medical markets. These systems are designed to either be attached to any HVAC system in a partial by-pass configuration or as stand-alone units. They range in air flow from 50 CFM to 2,000 CFM.
