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.

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.

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.

The phrase ” Buy American” should be more than a slobetgan.

No matter who you talk to today, many of the older people are saying we should only buy American made products. That, today, is easier said than done. First, many individuals that order on line ( and that is the majority of people) buy products that meet their needs at the best price and seldom search for its origin of manufacture. 

Pure Air Systems, Inc. has been manufacturing its fan powered, commercial grade HEPA based air filtration systems in the US from all US made components since 1985. Today almost 95% of all the components used in the manufacture of our HEPA Shield systems are made here in the U.S. And, since its inception in 1985, PAS has always put Made in the USA stickers on our filter cabinets.

Customers that are familiar with our systems are happy to pay the higher cost for the systems knowing that the quality of our systems will provide them with great air filtration for 15 to 20 years of service, with reasonable filter changes. and minimal maintenance, Over the years many of our customers purchased less expensive, made over seas products, but eventually came back to PAS because our systems perform so much better than 95% of our competition. In fact, Pure Air Systems, Inc, is now one of only 3 companies in the word that produce this type of HEPA based air filtration system.

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.

Filtration For Your 3D Printer

With over 13 years of experience in using FDM and FFF 3D style printers one learns quickly the various quirks in the operation of these printers. While they have improved dramatically since the 2011-2012 introduction of desk top printers, there are still some challenges when printing with various filament types. To be specific, ABS ( Acrylonitrile Butadiene Styrene ) has been one of the more popular materials with which to print. However, this material off-gasses when printing at 245 Degrees C and above and the odor can be quite significant. In addition, the gases produced along with some of the fine particles released during printing can become a health concern if not properly vented or isolated when printing occurs.

One of the other issues when printing with ABS is the layer separation that can take place if the object being printed cools to rapidly during the printing process. To minimize this issue you need to enclose the printer and keep the cold air drafts from falling on the printer bed. This enclosure can also also double as a mechanism to reduce the entry of the odors and particulate into the room. The use of a fan powered exhaust system attached to a vent in the enclosure along with a carbon media and HEPA filter will allow for continued use of the printer inside any room or enclosed area without compromising the environmental integrity of the room.

Pure Air Systems has been making fan powered HEPA and Carbon medial filters since 1985. These systems are designed to move from 50 CFM up to 2000 CFM with the ability to control the air volume in 1% increments. These metal framed units come in seven different configurations with the addition of a portable unit that is a prefect fit for the enclosures that would be placed over the 3D printers.

Pet Dander Is Not Removed By Furnace Filters

One of the strongest allergens is pet dander, especially cat dander and their reactions can be from mild irritation to full-blown respiratory distress. Dander is basically skin flakes that are shed by any animal, including humans. 

These skin flakes can be airborne for short periods of time but usually too heavy to be carried by the air currents in any home or building environment for any period of time. If a cat or dog is running through the house and runs by someone who is allergic to dander, there may be enough dander in the air to cause a reaction. If that person comes in contact with the animal then the dander can attach itself to their clothing or is discarded on the furniture from where they may lay. Once the person inhales the skin flakes their specific allergic reaction will begin and may last for a number of hours or all day. 

Because the dander is not always airborne, the air filters in your return air intake will not see much of that airborne particulate. It is often better to use a portable air filter such as a HEPA filter that uses a fan to pull the air through the room. These can be placed in a bedroom or family room, preferably where the animals do not often track. This will keep that area cleaner and a more significantly reduced level of animal dander.

Pure Air Systems offers a small, powerful, adjustable speed HEPA filter unit that is only 21 inches long and 13 inches square. It can move up to 500 CFM and has a variable speed motor for infinite air flow adjustment. It is easy to carry and can be placed on a table or even the floor if necessary. Putting a filtration device in a area that is considered a safe zone for humans offers the best option for keeping animal dander to a minimum.

Pure Air Systems – Real Content – Not Social Media

I must say that I am getting tired of all these Twitter, YouTube, Instagram, etc. sites that tell me things like: “If you look outside and see that liquid falling from the sky….that is rain. And let me tell you why it falls the way it does.”  Really,? Have we arrived at point in our lives that we can only verify what we saw because someone else used social media and told us it was real? 

These are some of the reasons why companies and individuals who actually have valuable and reliable content on their websites and blogs dislike social media. They now have to shift to the “Bizzaro World” approach to get anyone to pay attention. If you are looking for real content then take a look at the Pure Air Systems website. A company that is now 36 years old and one of only three companies left in the world that make this type of fan powered, commercial grade, HEPA filtration system.

In early days of PAS, a lot of content was written for the site that provided easy to understand technical information about all types of air filtration systems, including those sold by competitors. This part of the site was titled:  Pure Air University. It is still a viable section of the website and often used by those searching for real, technical, information written in a format that is easily understood by the laymen. This data forms the basis by which all types and styles of filters are rated and is still one of the most widely read of all the data on the site.
