Carbon For Odor Control

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.

Cigarette Smoke – Easy to See – Hard to Remove

Smoke from cigarettes and cigars is highly visible and has a distinct odor. It is pungent and will stick to any surface and re-release the odor for a long time. It will cling to clothing and stain hard surfaces over time. Of all the airborne contaminants we generate, cigarette smoke is the most difficult to remove from the air.

Smoke from cigarettes and cigars has both a particulate component and an odor component. Both difficult to capture using filtration systems. The odor can only be removed using carbon based media and the cigarette smoke will even plug up a HEPA filter over time.

The use of ozone generators or UV lights also do very little to alleviate this situation indoors and it is now  the reason smoking is prohibited in almost all indoor facilities, restaurants and eating establishments. It is just too difficult to mitigate with almost any filtration technology.

Pure Air Systems has been making high end, HEPA based, fan powered air filtration systems since 1985 and one of only three companies in the world that make systems for both the commercial and residential markets. The systems range in capacity from 50 DFM to 2000 CFM and can include a prefilter, scanned HEPA filter and carbon media. The systems now all use variable speed drive motors and are digitally controlled. The units are also capable of being used in 120/240 50/60hz applications.

Summer Months and Home Indoor Air Quality

For the majority of the U.S., Summer represents hot days, hot nights and in many parts of the U.S., high humidity. This means that for the most part people will remain indoors in their homes, offices and shopping areas in the presence of cool, air conditioning. 

While air conditioning keeps the interior space cool and removes the majority of the humidity, the lack of any outside fresh air means that all the air in the home, office, school or shopping areas is stagnant or stale. Without any type of effective air filtration, the levels of airborne particles (which can include, human skin, bug matter, airborne dust and debris of all types) will increase 10 fold. And, if there are animals present, then the potential for high concentrations of animal dander may occur.

In order to minimize the health hazards of breathing stale, polluted indoor air for long periods of time, we recommend using good air filters on your returns or consider putting one of our 600HS Plus HEPA systems on your ducted forced air HFAC system. With the unique partial-bypass installation concept it is possible to filter all the air in your house up to 24 times per day and introduce a small amount of outside, filtered fresh air without upsetting the AC temperature and humidity in your home.

Covid and the Mask Issue

The issue regarding masks and their effectiveness has been a constant battle in this country. Facts of how masks work and their value have been bashed by the uneducated and anti-vax groups for the past year with no viable, technical data to support their claims. N95 Style masks do provide some viable protection against sub-micron sized particles.

Pure Air Systems has been making HEPA based air filtration systems since 1985 and has over 36 years of experience in dealing with airborne allergens and pathogens. HEPA filters are used extensively in the CDC and pharmaceutical companies around the world. The N95 masks have similar particle reduction capabilities and are very affective in keeping the wearer safe from airborne viruses and bacteria.

For some strange reason people want to discount the science of air filtration in lieu-of nonsense spewed by the social media pawns. It is important that the general public do their own research and not listen to the TV pundits who are only trying to get their ratings up for their sponsors and are not interested in providing reliable information to the public.

Covid and its new strains will be with us for a long time and the more we debate the value of the masks the longer we put off making these mask issues a useful and necessary part of daily life the longer we will deal with the virus.

Chevrolet Nova – A Car After It’s Time

The Chevy Nova was made in the early 60’s through part of the 70’s and was somewhat popular as a mid sized, low cost vehicle. This car also had many mechanical issues and was dropped from the line up only to be resurrected as the Chevy Citation in the 80’s. Different design, same issues. When the Japanese entered the US car market they were surprised that General Motors ad chosen the name Nova because in Japanese this word means NO GO. This should have been a warning to GM not to use that name.

When Pure Air Systems came out with their HEPA filtration systems in 1985, the units were considered too expensive and the existing furnace type media filters were considered the best filters on the market. Ozone generators and Ion Generators were also sold as high efficiency air filter systems and were much less expensive than the HEPA units. However, like the Nova, these general duty air filtration filters and mechanical systems did not work as promised and are still sold today to unsuspecting consumers. 

The fan powered, commercial grade HEPA filtration systems by PAS are considered some of the best overall HEPA systems on the market. And, Pure Air Systems, Inc. is one of only 3 companies in the world that make this type of HEPA system with a wide range of sizes and housing configurations. The PAS line offers systems that range from 50 CFM to 2000 CFM using new ECM variable speed drive motors.

House of The Rising Sun

There are some songs that seem to transcend time and this one by Eric Burton and the Animals is not exception. For almost anyone alive today hearing the first 5 cords of this song instantly remind you of what comes next. There are products and companies that also fall into this category.

Pure Air Systems, Inc. Founded in 1985, is one of those companies. PAS was one of the first companies in North America to offer true HEPA based, fan powered, air filtration systems for both residential and commercial applications. The model 600HS was the first HEPA system that was designed to attach to any forced air, ducted HVAC system using the partial by-pass concept. This allowed the use of the 600, 1200 and 2000HS series units to used in any application for any size HVAC unit with the added ability to introduced fresh, filtered outside air in small quantities to help pressurize any environment.

Today, Pure Air Systems is one of only 3 companies in the world that produce this type of commercial grade HEPA air filtration system. These units also use the variable speed drive motors and can be programmed to adjust the speed ( air flow in CFM ) to suit the application.

Using Metal Instead of Plastic Composites

Many products that used to be fabricated from metal are now made by using an injection molding process and a wide variety of plastics to keep the cost and weight down. In many cases this option works as the strength of many of the composite plastics are very strong and will work for most applications.

In 1985 Pure Air Systems began its process of making fan powered, commercial grade, HEPA air filtration systems for both the residential and commercial markets. The cabinets used to house the filter components was mild steel that was powder coated. These rugged housings allowed for the use in both interior and exterior applications and provided a housing structure that would last 20 years or longer under heavy use.

The housings ranged in size from the small portable which is approximately 13 inches square by 21 inches long, the 600HS series which is 16 inches square by 34 inches long ( high ), The 1200 HS series which is 25 inches square by 48 inches long and the 2000HS series which is identical to the 1200HS in size. All of these units are fabricated from 16 gauge powder coated steel and are built to last.

Early in the 90’s. Pure Air Systems looked at the possibility of using strong, composite plastic materials in-lieu of metal housings but found both the cost and challenge of making a unit strong enough to hold the metal blowers, ECM motors and HEPA filter and associated prefilter material. In this case, metal was and has always been the best choice for making the high performance HEPA based air filtration systems.

Blockchain Filtration

Blockchain technology is in the news everyday and unless you have been hiding under a rock all you hear anymore is Cryptocurrency, Bitcoin and Blockchain. The advantages of using the blockchain process for storing data is the ability to have a secure set of data that cannot be changed or altered making it a very unique method of storing all types of encrypted data including Bitcoin.

Pure Air Systems has been manufacturing HEPA air filtration systems since 1985. Their fan powered commercial grade systems utilize a three-stage filter system. The first stage, is a dual-layer polyester ring panel filter. This captures much of the larger particles and protects the carbon filter and HEPA filter that follow. The carbon media unit that follows the prefilter, captures airborne gaseous pollutants. Lastly, the 99.99% scanned commercial grade HEPA filter that follows the Carbon filter captures over 99.99% of all particles 0.3 microns in size and lager.

As with the Blockchain technology, the three-stage filtration process used by Pure Air Systems in all of their systems capture all the particulate and retain it in their air filter components forever. HEPA filters are the primary filtration technology used by the CDC, hospitals, clinics, surgery suites, and the reduction/removal of airborne viruses such as the Covid-19 strain.

Tobacco Road

In the 60’s Eric Burton of the rock group The Animals sang a song about a lost soul. The name of the song was Tobacco Road. The animals and song went on to become an iconic part of early rock and roll. Along the same lines the product tobacco had also become one the most influential soft drugs in the US and around the world. Nicotine, one of the main components of cigarettes and other tobacco related products, is also one of the most addictive compounds legally allowed in every country in the world.

In addition to the nicotine that is harmful to the user, the cotinine that is released as a result of burning the nicotine is a sticky material that sticks to everything it touches and releases an odor that lingers for a long period of time. Attempting to remove this airborne gaseous compound is difficult as it requires both carbon for adsorption of the odor as well as filter media ( usually HEPA filters) to capture the very fine airborne particulates that are released by the cigarette.

Because of the nature of the two emissions both the carbon and media filters ( HEPA ) need to be changed frequently making it very expensive and challenging to remove cigarette smoke in a room or enclosed area. This is one of the major reasons whey smoking is now prohibited in almost every public building and most restaurants.
