Closing In On Airborne Mold

Mold is a common growth material that is normally found in damp environments or where there is little light or heat and there is the presence of water. When the mold spores the spores become airborne and for many individuals this organic material can cause severe reactions and respiratory dysfunctions. 

Mold spores are relatively large so they are easily captured by high end filtration systems such as HEPA filters or Merv rated filters of 17 or higher. These filters are much denser and can capture a very high percentage of the airborne mold spores. It is, however, important to know that you need to keep the HVAC fan running continuously if you want to pull the airborne spores back through the return air grills to the air filters.

Pure Air Systems has been making commercial based HEPA air filtration systems that are fan powered and include prefilters and carbon media. These systems are made from mild steel and are powder coated for use in all types of environments. These units range in capacity from 50 CFM for the portables up to 2,000 CFM for the larger systems. All of these units utilize variable speed drive motors and can be controlled digitally.

The PAS systems are used in the institutional, medical, industrial and residential markets to handle a wide range of airborne contaminants and are considered some of the best air filtration systems on the planet.

Air Filtration 101

The use of air filters for removing airborne particulates has been around for over 100 years. Today’s filtration technology is eons ahead of just using cheese cloth to filter our particles for fan powered device. The newer, blended filtration medias are much better at capturing small, sub-micron particles with higher capture rates and lower pressure drops over time.

Air filters range in efficiency from general duty, like furnace filters, to high capacity, high efficiency, like HEPA filters. For most home applications the general duty filters are used as they both help keep the cooling coils in the HVAC system clean as well as minimize the dust in your home. 

The higher efficiency filters, like HEPA, are used mostly in commercial applications like hospitals, clinics, surgery suites, chip manufacturing, clean rooms, laboratories and more. There are also HEPA based systems available for the residential market that utilize their own fan/motor system to augment the blower/motor assembly in the HVAC unit. HEPA filters have a much higher resistance to air flow but can capture particles as small as a virus. 

It should be noted, that the use of non-mechanical filtration devices such as ozone generators or electronic air cleaners are not really that effective at removing particles from the air. Ozone generators are really more effective on the reduction of airborne gaseous contaminants and electronic air cleaners need constant cleaning to make them work.

Indoor Air Quality

Indoor Air Quality has been an issue for enclosed spaces, homes, office buildings, medical facilities and industrial buildings since the early 70’s. The issues of people suffering from a wide range of health issues, mostly respiratory in nature, became more acute once the building industry started to build tighter buildings that offered little or no outside air intrusion. This process reduced the energy costs, but increased the amount of stale air and concentrations of gaseous pollutants and airborne particulate that are generated from most materials, chemicals, plants, animals and manufacturing processes.

Using only recirculating air through the air handlers and HVAC units and not allowing any outside, fresh air increased the IAQ issues. Adding outside air only added to the amount of particulate already present in the occupied space.

Pure Air Systems, based in Indiana, had developed a variety of commercial grade, fan powered, HEPA filter systems that could be used to both filter the air in the space as well as add small amounts of filtered outside air. By only adding 50 CMF to 100 CFM of outside air through the PAS units, one air handler could introduce up to 6,000 CFM of fresh, filtered outside air every hour and adding that to the recirculated air also being filtered, created a much healthier environment and reduced the amount of headaches, and respiratory issues in most residential and commercial operations.

Adding the small amounts of outside air, even on hot and very cold days, had a minimal affect on the amount of energy required to heat and cool the indoor environment. By adding an actuator to the inlet damper, it is possible to modulate the amount of outside air so that more or less air could be introduced depending upon weather or the conditions in the occupied space.

Pure Air Systems. American Made.

Founded in 1985, Pure Air Systems was one of the first companies to introduce true, commercial grade, fan powered HEPA air filtration systems. The first unit, model 600H, was the base model using a standard 120 volt, 60Hz GE motor, Lau blowers, scanned HEPA filters, carbon media packs and ring panel pre-filters and switches and wire harnesses. All American made. 

Today, Pure Air Systems has 5 different models ranging from 50 CFM to 2000 CFM using the same metal housings, HEPA filters, carbon media packs but with the new variable speed 120/240 volt 50/60HZ motors, digital controllers and pressure gauges. Again, all of these components are currently being made in the USA. In addition, PAS is now one of only three companies in the world that manufacture these commercial grade HEPA air filtration systems.

Making products using US made components in today’s world creates some unusual issues. With most companies using components made in China or other overseas countries, competing with US made components is becoming more difficult. However, the Pure Air Systems units historically have a 15 to 20 year life cycle even in heavy duty operations. The cost may be higher but the performance is unmatched when comparing to similar products made in China.

HEPA Systems For New Intel Chip Manufacturing Facilities

Intel is investing $20 Billion dollars to build two state-of-the-art Micro Chip manufacturing plants in Albany, Ohio. Chip manufacturing is done in Class 10 and Class 100 clean room facilities which are constantly being cleaned by HEPA filters with the rooms being under positive air pressure.

Chips are comprised of multiple layers and then assembled together. These layers are highly sensitive to any airborne particulate, even in the sub-micron level, as the dust particle will destroy the chips function and short it out when in use. The types of HEPA filters used in the manufacturing and assembly areas are normally comprised of a series of HEPA’s in banks. They use HEPA, ULPA and SULPA HEPA filters that will remove 99.9999% of all particles 0.12 microns and smaller. As as comparison, the Human hair is about 100 microns in diameter.

Pure Air Systems has been providing commercial grade, fan powered, scanned HEPA filters ( 99.99% at 0.3 microns) since 1985. Many of these systems have been and are being used in smaller micro chip operations, medical facilities, hospitals, military and institutional plants. The PAS systems range from 50 CFM up to 2000 CFM and can include Carbon media along with a Prefilter.

Time To Consider Whole House Air Filtration

For most home owners, having an air filter in the main return air duct next to the HVAC fan system or separate filters in the numerous return air outlets in the rooms of the house, constitute whole house air filtration. 99% of these filters are general duty filters that are capable of removing very large airborne particles and not adding any static pressure load to the HVAC fans. The compromise here is that you are trading air flow for not so good air filtration.

In 1985, Pure Air Systems introduced a new HEPA based, fan powered air filtration system that would provide a much higher level of removing much smaller airborne particulate including bateria and some viruses. By using a concept called, partial by-pass system, PAS can attach their HEPA units to the return air side of the HVAC ducting system and because the PAS systems have their own fan, they will not impede the performance of the main HVAC blower/motor assembly.  In addition, the PAS units also incorporate a prefilter and carbon media filter for removal of odors and gaseous pollutants. 

Since the inception of the partial by-pass concept, PAS has sold thousands of these units to home owners across North America and has even placed some on board ships and in the hospitality industry. This concept is easy to install and can be retrofitted on existing, ducted HVAC systems in any application.

Pure Air Systems Shares Rarified Air

Created in 1985 by Don Musilli, Pure Air Systems was one of many companies offering air filtration systems for the commercial and residential markets. But the separation from the competition began shortly thereafter. From the beginning, PAS used an all metal housings, Lau Blowers, GE Motors and commercial grade prefiters, carbon media and HEPA filters. The initial units sold for $695.00. Over time, PAS added other units to their line up and in 1998 became one of the first powered fan filter companies to use the new GE ECM variable speed drive motors. 

The addition of the new motors and expansion to a 9,000 sq. ft. building allowed PAS to expand their product line to 7 different size air filtration systems all of them now using the upgraded, digitally controlled variable speed drive motors. The ability for the motors to be 120/240 50/60 Hz created a new market overseas for the larger systems. The new HPS portable unit opened the doors to more medical markets and the Covid – 19 global pandemic created a whole new market for commercial grade HEPA air filtration systems.

Today, there are only two other companies in the world that make a fan powered, commercial grade HEPA air filtration unit handling up to 2,000 CFM and as low as 50 CFM. With material costs for metal and other components increasing rapidly, it is much more difficult for companies to offer products such as the ones from Pure Air Systems.

HEPA Filters. High Efficiency Particulate Absolute

HEPA filters were developed in the early 1940’s during the creationg of the atomic bomb.The use of radioactive materials in the making of the bomb created extreme health hazards for the technicians and engineers that had to handle this type of material. Due the extremely small size of the radioactive particles ( Sub-micron in size ), readily available air filter media like furnace filters, were totally useless in reducing the levels of radioactive particulate. They needed a filter material that could absolutely remove and capture these tiny particles. 

After trying a number of materials a process using a wet laid paper type material infused with tiny pieces of glass was used to develop a very dense material that was capable of filtering out these tiny sub-micron particles. The paper like material was formed into an accordian style form with pieces of aluminum sandwiched beteween each folded layer to protect the paper-like media as it was relatively fragile and could abrade by rubbing on itself.

The filter pack was placed inside a square medtal housing and was glued in place. The outside parameter of the metal housing had a neoprene type gasket so when it was placed in a sheet metal duct it would compress the gasket to form a leak-tight seal. These filters had an initial efficiency of capturing 99.97% of all particles 0.3 microns and larger and as it got dirtier its efficiency increased. The use of this HEPA filter allowed the technicians to work in a safer environment culminating in the eventual creation of the two bombs used on Japan to end WWII.

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.

Pure Air Systems manufacturing a complete line of HEPA based, fan powered filtration systems for the residential, commercial, institutional and medical markets. We are currently producing a large number of HEPA based air filtration systems for the medical and commercial markets to assit them in removing Covid-19 in many of their operations. PAS is as major supplier of HEPA systems throughout North America.
