You can either put you head in the proverbial sand like the Ostrich and believe this is not a problem or grasp the real issue of this virus being around forever and changing and adapting to the new vaccines that are currently on the market. Too many people use other methods of gathering data, especially social media, on health care issues rather than from their medical professionals. This never ceases to amaze me.

Viruses are extremely small and very light and can travel up to 20 feet or more when expelled from a human mouth. While we realize many of the face masks are not capable of removing all of the viruses, they are a great barrier non the less. 

The use of air filters in your home or office are minimally capable of removing very little of the airborne viruses. The only air filters that can do that are HEPA filters and those are normally used in hospitals, surgery rooms and chip manufacturing. However, there is a company that has been around for over 37 years that makes a HEPA air filtration system that can be attached to any HVAC ducted residential system and even used as a stand-alone unit. 

Pure Air Systems has been making commercial grade HEPA and Carbon based air filtration units since 1985. These units range in air flow capacity from 50 CFM up to 2,000 CFM and come in seven different configurations. Over the past 37 years these units have been used in a wide range of air  filtration applications around the world. Pure Air Systems is now one of only 3 companies in the world that make this type of fan powered, HEPA based air filtration system.

HEPA filters are the best method of removing sub-micron airborne contaminants including, viruses, bacteria, dust particles and airborne allergens ( mold, pollen, etc.).

One of the challenges of using HEPA filters in a residential application is how the HEPA filter is installed to best gather the greatest amount of airborne particles from all rooms of the home. Most air filters in residential HVAC systems are either placed in the air returns for each room or one largepr filter is placed at the return air inlet of the main HVAC fan unit. 

Since HEPA filters have a much higher resistance to air flow than standard duty air filters, they need to be placed in a cabinet that includes its own blower/motor section to assist the air flow through the HVAC system so there is no disruption to the air flow from the HVAC unit. 

Pure Air Systems developed a HEPA filtration system that incorporated its own blower/motor unit along with a true commercial grade HEPA filter, prefilter and carbon media filter. This metal framed housing unit could be attached to the return air side of the HVAC system in what is called a “partial pass” concept. In essence, the HEPA system would pull anywhere from 600 CFM up to 2000 CFM of the return air ( the later used mostly in commercial systems) and then return it back into the HVAC system on the supply side. In this manner the HEPA system would clean all the air in the house after the 3rd or 4th pass. Or, approximately 30 to 50 times  day, depending on how often the HVAC fan system runs.

The PAS units all utililze the newer variable speed drive, digitially controlled motors that can be programmed to operate in sync with any HVAC system.

Removing odors and gaseous pollutants from any environment is much difficult than removing airborne particulate. There are a number of air filter types that can easily remove airborne dust, but the removal of airborne odors and gases requires some very specific materials that can effectively adsorb these organic or inorganic molecules.

The most common material used to remove odors is activated carbon ( charcoal) which comes in a number of sizes. The most common is cocoanut shell carbon that is usually around 1/4″ in size and is often enclosed in a mesh type material or sometimes in a fine opening screen container. Carbon can be used in both air and water for the extraction of gaseous pollutants, making it one of the more popular materials on the market.

When cocoanut shells are placed in a high temperature oven under pressure it expands the surface area of the material and then makes it into a carbon material. The expansion to the shell gives the material a very high surface area and the ability to adsorb up to 100 times its own weight in gaseous pollutants. This means that a small amount of carbon material can remove a large amount of the odors and last a long period of time. 

Pure Air Systems has been manufacturing HEPA and Carbon based, fan powered, commercial grade air filter systems since 1985. The various systems available from PAS include carbon media as a standard part of the filtration unit along with a prefilter an HEPA filter. In cases where a customer only has an odor or gaseous pollutant issue, Pure Air Systems can remove the HEPA filter and replace it with an all carbon bed of material. Depending upon the odor challenge, the systems can hold from as little as 8 lbs of carbon up to 60 lbs of carbon material. And the air flow capacity of the systems range from 50 CFM to 2000 CFM.

Amazon and other online stores have created a scenario where people look at items that seem to be similar with various pricing. This has led people to believe that all products are similar and price becomes the deciding factor. For the manufacturers of these products it is difficult to up sell the their products. People will typically go to the best priced selection and read some reviews then make their choice. It is for this reason that many of the companies that make high-end products or products with proven superior performance elect not to market their products on Amazon and other similar online websites. They, instead, market them on their own websites.

So, for the astute buyer, often times you are better served to purchase the products from your selected company product website. They may charge a little more and often don’t offer free shipping, but their products are usually far superior and will last and perform better than many of those lesser expensive copies from your favorite online store.

Pure Air Systems has been offering their products online since 1990. Their commercial grade, fan-powered HEPA air filtration systems are some of the best in the world. With an average operating time of 15 to 20 years, these made in the US systems perform as advertised and the service from PAS is second to none.

Carbon that is used for odor control if often made from expanded cocoanut shell carbon. This type of carbon has a high surface area and very high ratio of molecular adsorption to weight of carbon. This makes this material suitable for both adsorption of organic and inorganic odors and gaseous pollutants in both air and water applications.

For general odors found in most homes; typically pet, cooking and carpet odors, carbon filters placed in the HVAC system will be capable of removing about 50% of those odors with a replacement cycle of once every two months.

For commercial and industrial applications, it may be necessary to use large carbon beds, 10 – 20lb pads of carbon, to significantly reduce the the gaseous pollutants. And, in some cases, a catalytic material like zeolite may be required to enhance the adsorption of the gaseous pollutants. Depending upon the amount of pollutant being released it may be necessary to replace these carbon pads as often as once a week. 

Odors such those produced by cigarettes are some of the most difficult to remove as the nicotine smoke produces a sticky residue with adheres to almost any surface and releases that odor for long periods of time. Carbon can help in these cases but replacement of the carbon can be up to once a day.

Pure Air Systems was founded in 1985 and at that time the electric motors used in their HEPA based air filtration systems were typical wound motors. These motors were only capable of running either at one speed, or 3 speeds if adjusted to the speed controller. They were also either 120 volt, 60 Hz or 240 volt, 50Hz. 

In 1998, PAS along with General Electric, started to play with the new ECM, variable speed drive motors that were magnet driven and not the typical induction motors used in the past. These new motors could run forwards, backwards and could controlled to run at 1% of power up to 100% of power in 1 percent increments. And, they were rated from 1/3rd HP up to 1 HP using the same base unit but by changing the drive add-on could be changed from 1/3rd HP or 1/2 HP to 3/4 or 1 HP simply by changing the controller section. 

In addition, by using digital controllers, the customers had the ability to change the speed of the motors and the level of filtration from any location in the room or proximate to the filter systems. These units could also be programmed to operate on a pressure differential basis so as to speed up the fan motor when the HEPA filters started to load up and create more static load. This allowed for continuous speeds throughout the life cycle of the HEPA filter.

The newer versions of these motors now allow for complete programing functions either from the factory or by the end user with some minor education by the factory. These newer motors, like the original variable speed drive motors, are now 120/240 50/60Hz so they can easily be adapted to working anywhere in the world. These new motors are used on the complete line of HEPA based air filtration systems offered by PAS. Models, 600HS, 1200HS, 2000HS, and the HPS Portable HEPA filter systems.

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.

For many years carbon media or expanded carbon, has been used for the reduction and removal of organic and inorganic gaseous pollutants. Expanded carbon or charcoal is produced using heat under high pressure that creates a surface area that has thousands of tiny openings that are capable of adsorbing gaseous molecules much higher in weight than the carbon itself. 

While carbon granules are often used in liquid filtration, the most common use is in air filtration whether in a stand alone filter or fan powered air filtration system. Carbon media filters have a fair amount of resistance and are therefore more often used in conjunction with a fan powered unit. 

Even though the expanded carbon has a high adsorption rate to weight of the carbon media, it will, over time, load up and stop adsorbing the odors or gases. Replacement cycles can be as long as once every 6 months to once every 6 weeks depending upon the severity of the gaseous pollutant.
