Many libraries, businesses, schools, medical facilities and even homes no longer rely on the ubiquitous phone book ( white or yellow pages) to get phone numbers and addresses for individuals or businesses. The old yellow pages  line that said ” let your fingers do the walking” has been changed to “let your fingers do the typing.” The use of the computer or digital device has replaced, for the most part, the phone book. Soon, like the Dodo bird, the telephone book, as we know it, will become extinct.

While there is still a portion of the population that either refuses to become computer literate or just can’t figure out how to make anything more complicated than a standard phone work, the vast majority of people use digital devices to not only find individuals and businesses but also to save or “archive” this information for future reference. All with the touch of  a few keys or buttons on your iPhone.

Not only can you find information faster, but you can access rating information on that specific product or service in an instant from a number of respected sources. You can’t do that with a phone book. This is why most companies today put more money, time and serious effort in developing a website and e-mail addresses to provide for a connection to their business from anyone anywhere around the world in less than 2 seconds. You can’t do that with a phone book. Oh yeah….and you can contact the business from your computer and ask them to give you a price or answer more questions about their product or service….without having to call them.

As I mentioned earlier, companies that use their websites as their primary method of marketing their products or services put a lot of time and money into developing a site that is informative, educational, detail specific, includes typical applications and even allows you to purchase their products on line.

Pure Air Systems has been manufacturing and marketing its line of HEPA and Carbon based air filtration systems since 1985. It was one of the first air filter companies to build a website in the early 90’s when .com was not even a term. Over the years PAS has modified, changed, altered and improved its web site to include a lot of useful information including typical applications, specific references showing how other companies utilize the systems and Pure Air University, a section dedicated to inform you on how filtration and carbon adsorption actually works.

You can even order replacement filters and some of the smaller systems online. And of course, there is a section that allows you to send questions directly to the PAS staff so that your specific problem or application can be addressed.

You always hear about the eternal optimist that says you can always turn a negative into a positive if you just rethink the problem. All too often we have something happen in our lives that creates a negative feeling or puts us in a negative mood. But these negative thoughts are a waste of energy. Instead of dwelling on what could go wrong or did go wrong, look at all the positive things in you life and don’t waste energy worrying about the negative aspects of the issue.

The title of this blog relates to turning two negatives into a positive and while your life  maybe filled with multiple negative thoughts the two negatives I am referring to relate to negative pressure of the physics kind.

Pure Air Systems has been making HEPA and Carbon based, fan powered, commercial grade air filtration systems since 1985. The use of certified, commercial grade HEPA filters creates a design issue in how you incorporate the motor/blower assembly and HEPA filter to obtain maximum performance with minimal noise and air turbulence.

HEPA filters, by their nature, have a relatively high resistance to air flow due to the extremely dense HEPA paper that is used in the fabrication of the filter. When moving air through a fan/motor assembly with a HEPA filter in line you have two options. You can put the fan in front of the HEPA and blow air through the HEPA filter keeping the fan/motor assembly in the dirty air stream or place the HEPA in front of the fan/motor assembly.

Since the resistance to moving air across the HEPA is so high ( over 1.0 inches as measured in water column) pushing the air through the HEPA filter creates an air buffeting affect and requires more horsepower to push the air through the filter. By placing the fan/motor assembly on the clean air side or “negative” side of the HEPA you get a very smooth flow of air, little or no buffeting and a reduction in horsepower requirements.

The HEPA systems manufactured by Pure Air Systems also incorporate a carbon media filter and a polyester, dual layer ring panel roughing filter. All of these filters are placed ahead of the fan/motor assembly. So they are all on the negative side of the blower and offer the same benefit of having a smooth, non-buffeting air flow across their surface areas and keep the blower and motor clean. So in essence, you are turning three negatives into a positive.

Many other companies that utilize HEPA filters in their systems place their blower/motor assembly ahead of the HEPA and this creates more noise fills up the HEPA filter faster as it tends to push the dirt into the HEPA paper rather than pull the dirt through, which is a more efficient way of using the HEPA filter.

Pure Air Systems has been making HEPA and Carbon based, fan powered air filtration systems since 1985. In the late 1990’s PAS decided to offer a separate product line of air filters that would offer the same type of performance as the fan powered filters but compete with the plain air filters being used in the HVAC systems and commercial air handlers.

Pure Air Systems has been using a polyester, dual layer, commercial grade, ring panel filter as the prefilter or roughing filter in all of its units since the inception of the company. These ring panel filters use two different grades of media, one on the air entering side ( dirty air) and one on the air leaving side. The air entering side is slightly thicker and a little more dense than the media used on the air leaving side. These two medias have a metal ring frame that is placed inside the two media panels. The media panels are then heat sealed around the metal frame.

The dual layer filters are a MERV 8 rated filter and have  a high dust holding capacity with a low pressure drop even as the filter loads up. The reason for the low pressure drop is the dual layer media concept. This approach provides for a funneling affect that allows for more capture of the larger dust particles which in turn capture the smaller airborne particles. With the amount of media on the filters the air flow to sq. ft. of media is relatively low. Meaning the filters have a lot of media “surface” areas to capture dust particles and thus it will take longer to fill up the filter space with dust. This means lower pressure drops and longer filter life. In most cases these filters only have  to be replace 3 to 4 times a year even for industrial applications.

These ring panel filters come in all the standard sizes and can be made into any custom size filter when requested by the customer. They are easy to install and easy to remove and are simply thrown away at the appropriate life cycle of the filter.

In 2008 Pure Air Systems introduced a new filter that combined the Polyester media and carbon in the ring panel design. The carbon media is placed in between the two medias and this filter offers the best of both worlds. Particulate and odor or gas removal with one filter. Like the standard dual layer filters these “combo” filters come in all the standard sizes and are available in custom sizes as well.

The combo carbon filters can be supplied with three different levels of carbon. The lighter, smaller amounts are best suited for the residential HVAC systems as these have the lowest pressure drop of the group. The medium and high capacity combo carbon filters are better suited to the commercial market or for applications where a significant odor or gas is present.

With the growing population and the increased demand for health care and drugs around the world, the pharmaceutical industry is growing to meet this demand. While there are a number of large multinational drug companies there are also a lot of smaller pharmaceutical companies that produce both generic versions of the name brand drugs as well as vitamins and other drug supplements.

For most people who take drugs the dose is small enough that there is usually no serious side effects. However, during the manufacturing of the drugs the amount of drug compound that is processed at any one time, which is usually very high concentrations, can be lethal if the technician working in the plant is exposed. To ensure this doesn’t happen the pharmaceutical industry employs hundreds of HEPA filters throughout the manufacturing process and in the plant to remove any of the potential airborne drug compounds.

Pure Air Systems has been making commercial grade, fan powered, certified HEPA filtration systems since 1985. PAS has hundreds of these systems in pharmaceutical plants around the world. These systems use a certified HEPA that has a minimum efficiency of 99.99% on 0.3 microns or smaller. It also uses an ECM digitally controlled 120/240 volt, 50/60Hz motor that has variable speed or variable volume performance.

Since many of the process operations where drugs are made are small to medium in size and capacity the use of the PAS HEPA systems is a perfect match. The PAS units can operate from as low as 100 CFM to as high as 2000 CFM and have variable capability in  between those volumes. This allows the manufacturer to use one HEPA system for a process line that may vary in capacity and drug dust volume. The PAS HEPA system can be automatically or manually adjusted to vary its speed or volume in 1% increments, making this unit one of the most versatile HEPA systems on the market today.

In addition, the fact that the PAS units have a 120/240 volt, 50/60 Hz motor allows for use anywhere in the world. This is an advantage for those drug companies that have plants in North America as well as overseas where much of the electrical requirements are for 220 volt, 50 Hz motors.

Pure Air Systems offers a complete line of HEPA and Carbon based air filtration systems as well as ancillary filter products. To view our complete line of systems please go to our website at: www.pureairsystems. com

Remember when Charlton Heston was being carted away on a stretcher in the movie Solylent Green and he shouted out these words? The world’s food shortage was at crisis levels and plankton from the sea was being made into a food substitute called soylent. They had soylent red, blue, yellow and green. Everyone assumed that since this was the only food source available ( and they could afford) that they believed this was good enough to sustain their lives. And since everyone was eating it, it had to be okay…..and soylent green was the best tasting. Hmmm..wonder why?

I also wonder what would happen if everyone found out that soylent green…the best tasting soylent…was made from their fellow man?  Would they still buy it? Would they convince themselves that food was more precious and after all people die every day? After all if enough people believe it is okay…why concern yourself about it.

Today, with over 7 billion people on this planet, the ability to produce enough food to feed the growing population is of some concern to a lot of countries.  And, along with food shortages, the quality  and availability of  water and  quality of the air is also in jeopardy. It’s funny how we take clean water and air for granted. Even with newer technologies and stricter environmental laws being put in place we seem to be on the short side of a losing battle.

It’s interesting to note, that many people will go through the expense of either buying bottled water or putting in a water treatment unit in their homes to ensure they are getting pure, non-contaminated drinking water. Using bottled water or a filtration system will remove odors and some tastes associated with chemicals used to treat the water…and so they associate good taste with better water. However, when it comes to the air they breathe, if they can’t smell or taste anything in the air then it is okay. In reality, nothing could be further from the truth.

Much of the air we breathe in homes, offices, shopping malls and in urban areas has a much higher level of suspended sub-micron sized airborne particulate than we believe. And, unlike tainted water or spoiled food which we can immediately react to, high concentrations of airborne particulate in the air we breathe is never noticed. And, since everyone around us is not falling over dead from breathing the same air….it’s entirely okay.

Over time, breathing in large concentrations of harmful airborne contaminants can cause any number of respiratory or allergic dysfunctions. And, even breathing in low concentrations of certain airborne chemicals and gases can be deadly. Of course then you could become part of the food chain maybe end up as soylent green.

Pure Air Systems has been manufacturing a line of commercial grade, certified HEPA and Carbon based air filtration systems since 1985. These systems are designed to remove up to 99.99% of all airborne particulate that is 0.3 microns or larger and approaches the same efficiency with smaller particles. These systems are perfectly suited for homes, offices, commercial buildings and industrial and institutional operations.

Almost every home in the US is heated and/or cooled using a forced air ducted ventilation system attached to a heating/cooling system. The vast majority of these systems are designed to move a certain amount of CFM of air to adequately heat or cool the living spaces. In addition, many of these systems incorporate some type of air filtration device; either a pleated or box style filter or a more  sophisticated high efficiency air filtration system. In either case these filtering devices can reduce the air flow through the ducted ventilation system.

All HVAC systems are designed to move a certain amount of air, as measured in cubic feet per minute or CFM at a certain resistance or static pressure, as measured in inches of water using a fan motor with enough horse power to move the warm or cold air through the duct work an into the living spaces. Unfortunately, most HVAC systems do not take into account the resistance across the air filter or filtration device and this added static pressure can reduce the air flow through the system thus taking longer to heat or cool the living spaces. This both increases the operational costs as well as providing for a less than comfortable environment.

Pure Air Systems manufactures a line of HEPA and Carbon commercial grade, high performance air filtration systems that are designed to attach to the return air side of any forced air ducted heating /cooling system. These fan powered units are designed to assist the heating/cooling fan system but taking up any additional static pressure across the HEPA and Carbon media so the HVAC fan only sees the static resistance from the duct work. This allows the HVAC system to operate as designed and heat and cool the house effectively and efficiently.

Pure Air Systems is one of only a few companies that provide fan powered units and it is the only air filtration company that uses the ECM, digitally controlled motors that can run in sync with the ECM motors now used in all the new HVAC systems. In addition the Pure Air Systems units can be used as stand alone systems and move HEPA filtered air throughout any living environment without being attached to an HVAC system. This is very important for those environments where a non-ducted heating cooling system is utilized.

It is important to be aware of these issues since you want to get the best performance and lowest operating costs from your new high efficiency heating/cooling systems.

With only a little over a month left before the midterm elections, the amount of discussion and controversy over who can do a better job of running the country has overtaken any and all other news. Unfortunately like most issues that resonate with the public, everyone wants someone to do something for them and take away something from everyone else. While we want to believe there is a consensus of opinion in the US, we are really made up of 300 million special interest groups.

We like to think we are capable of compromise but more often than not we really want things done our way and to suit our own purposes first, then everyone else second. This is just the nature of human beings. We feel strongly about some issue or person and find all the information that conforms to our way of thinking to substantiate our beliefs. We use this same approach for forming an opinion about products, companies and services in the market.

Companies spend millions of dollars on advertising their products or services to get you to shop with them rather than the competition. People have been conditioned that they can get what they want, when they want it for the price they want to pay. All they have to do is go on-line to find just the right item for the price they feel is reasonable and have it in less than a week. They really don’t much care where it was made or even if they recognize the company name. They perceive that all products and services are the same and price is the only difference. This makes it difficult for a company to get people to buy from them on a regular basis. People will shift loyalties from month to month and day to day.

So, the only way to capture some form of loyalty with the public is to have a product or service that performs consistently better than anyone else all the time. This is difficult in today’s market…not only for companies but individuals trying to run for office and telling everyone they will do a better job for you.

Pure Air Systems has been manufacturing HEPA and Carbon based air filtration systems for the residential, commercial, industrial and institutional markets since 1985. As a result of their commitment to providing only the highest quality, best performing air filtration systems, companies and individuals continue to purchase their systems because they have found nothing works better for their applications than the PAS product line….nothing.

Twitter, Facebook, LinkedIn, Blogs, ipad, iphone, droid smart phones….information is now available 24/7 from everywhere around the world on any subject you can think of written by anybody who can text a message or send a photo or video. Little of it is vetted and much of it is slanted with a personal bias! On top of that we can now all interact with this information either by direct reply to the author or by attending any one of a thousand chat rooms or discussion areas to offer our own opinions or comments. Who needs the news media when you have access to news as it happens where it happens?

Much of the news ( information) today is colored by the group or authors political, economic, social or religious beliefs. Fair and Balanced or World News Tonight and all the news slogans are just that…pat slogans that mean little other than an opportunity to get you hooked on their network. It is up to you to sift through the fog of material and find out as much of the truth as possible. It is possible to have viewers see an incident take place and have the commentator give an opposite account of what is taking place before their eyes and they will take the verbal information as gospel. Scary and unnerving.

This same process takes place with advertising and product performance information. Someone describes a product and its capabilities and show you how it works and somehow as you watch the demonstration you don’t really believe it can do that. Yet…you believe the information given to you. You need to “Listen with your eyes”. If what you see doesn’t make any sense then more than likely it isn’t correct…no matter what someone is telling you.

This is especially true within the air filtration industry. There is a lot of “hype” used to get you interested in a product or process and more often than not the performance of the equipment explained in the brochure is not how the product will perform when you use it. As the old saying goes..” the proof of the pudding is in the tasting”.

All too often a company that makes an air filter, air filtration system or air purifying system tells you the product will take out all the harmful airborne contaminants or remove the odors and gases from your home or office and never needs to be cleaned and there are no filters to replace. In any case you need to determine the true performance of the product by trying it yourself. Don’t believe what someone tells you. Do your own research…there is plenty of material out there that can satisfy your need for information…accurate information.

Over the past year Geico, the auto insurance company, has been using some comedy in their commercials. The latest involves the old line of “how much wood can a wood chuck, chuck…showing wood chucks throwing (chucking) wood into a  river. An old man comes by and says ” hey, wood chucks stop chucking wood into my river!” I found this amusing but I’m sure others found it ridiculous.

The point is that the commercial gets your attention and whether you like the product or the commercial you remember it. And that is the whole point of making this type of commercial. It differentiates it from other bland commercials and ads.

The ability to differentiate or separate your product or company from the competition is a age old challenge for all businesses today. Trying to tell someone your product or service is really better than the other similar or “like” business is very difficult. Often the best way to really separate yourself from the competition is to do what you do better than anyone else and be consistent. Continue to add value to your service or product line and any changes you make need to fill a known void in demand. Sound simple, its not.

Pure Air Systems is 25 years old this month. In 1985 the company was originally called Halcyon but later changed its name to Pure Air Systems to better reflect the products that it manufactured. In today’s business world being around for 25 years is quite an achievement and we are proud of the fact that individuals and corporations still view our products as some of the best and most reliable air filtration systems on the market.

In 1985 indoor air pollution was just coming into its own. There were individuals who suffered from being exposed to various airborne chemicals and particulate in homes and buildings. Most often these people were considered a little left of center and few people in the medical field actually recognized these issues as real physical problems. The term that was coined at the time to describe the people who suffered was ” environmentally ill” or EI.

Today we know that many of the building materials used in the 60’s, 70’s and 80’s contained chemicals that would off gas and create some significant indoor air quality issues. In addition the total lack of fresh air ventilation combined with minimal filtration in the air handling units created high CO2 levels as well as high concentrations of respirable sized particulate. Now those people who were considered environmentally ill actually suffered from chemical sensitivities developed by long term exposure to these airborne contaminants.

Pure Air Systems was the first US air filtration manufacturer to offer true, certified HEPA filters for the residential market. In 1985 only firms that manufactured electronic devices the government, laboratories and some hospitals used HEPA filters. Today, HEPA filters are used in hundreds of applications in every corner of the world….. and Pure Air Systems has its systems in most of those applications and a majority of overseas countries.

In addition to the HEPA filters used in our systems, we also incorporate true, industrial grade carbon media for adsorption of odors and gases. Carbon is standard in all the Pure Air Systems fan powered air filtration systems as are the dual layer polyester prefilter medias. These filters capture all the larger particles so that only the small, less than 10 micron sized particles get to the HEPA filter providing a longer life for the HEPA itself.

Pure Air Systems was also the first air filtration company to use the new GE ECM digitally controlled, variable speed, dual voltage motors. These motors were incorporated into our devices in 1999 and 2000. Today these motors are used in almost every HVAC air handling system and air and water moving devices in the market today. These motors allowed our overseas customers that use 220 volt 50 Hz electrical current to use our systems. Today, over 35% of our new business comes from the overseas markets.

Pure Air Systems offers a wide range of HEPA based and Carbon based fan powered air filtration devices. They also offer a line of air filters and carbon media filters for the residential and light industrial markets.
