Pressurizing Your Home With PAS HEPA Filtration Systems

The majority of most homeowners are not aware that if their HVAC system is not properly balanced, when the heating/cooling fan system comes on the house may be pulling in outside air into their environment. This is referred to as the house being negative. Since your home is not really air tight, anytime the HVAC fan comes on the system will pull air through the returns and push the cooled or heated air our the supply ducts and registers and if there is more return than supply outside air will come in and make up that difference. 

This is a significant challenge as the air being pulled in from the outside will contain fine airborne particulate and some gaseous pollutants especially if you are near a road or high traffic area. This airborne dust is usually not captured in any of the air filters that are part of your HVAC system so this particulate matter will usually settle out on your floors, furniture and counter tops.

In 1985 Pure Air Systems was created and it was one of the first companies to offer true fan powered, certified HEPA air filtration systems for the residential market. The first model, 600HS was designed to attach to the return air side of the ducted heating/cooling system and filter a portion of the air in the house constantly when the fan was running. In most cases it can filter all the air in the house 24 to 48 times per day. 

One of the other advantages of this system was the inclusion of both a ring panel prefilter and true carbon media filter so removal of fine sub-micron particulate and gaseous pollutants was also accomplished. In addition, it is possible to introduce a small amount of outside air into the 600HS, or whichever PAS unit you are using, and this will fill filter any of the air coming into the house and help to maintain a more balance house pressure while still cleaning all the air in the house. And because this small amount of outside air is being introduced prior to the HVAC unit. all of it will be both filtered and heated or cooled.

HEPA Filtration Systems As Air Booster

Using HEPA filtration systems as air moving boosters is fairly common and in most cases necessary. If you have a multiple number of pick up points from which you want to remove contaminated air you need to understand the concept of air flow resistance or pressure drop.

When moving air through any type of duct system you have to take into consideration the resistance of air flow through the duct especially if it is flexible duct and you have some 45 degree and 90 degree bends. Air flow resistance is measured in inches and the higher the number the greater the resistance the larger the horsepower has to be on the motor/blower system that is moving that air from one point to another.

If you have any type of air filtration device in the air flow system that being used to remove the contaminants you also have to take into account the static pressure loss across that filter as well. If it is a HEPA filter you have a significant pressure drop which needs to be added into the total line loss when designing the blower/motor system.

Pure Air Systems has been making fan powered HEPA based air filtration systems since 1985. They use variable speed drive ECM motors on all their systems that adjust automatically by speeding up as the pressure drop across the HEPA filter increases.

Since Pure Air Systems makes HEPA filtration systems that are fan powered they can be used as boosters for moving air through an entire ducted system to maintain the proper carrying velocities through the ductwork even as the HEPA filters load up.

It takes a lot of power to move air through ductwork and a filter so using the PAS systems makes sense. The models range from 600 CFM to 2000 CFM air flow capability using 1/3, 3/4 or 1 HP ECM motors. PAS is one of the few companies in the world that make high end, fan powered, commercial grade HEPA air filtration systems that can be used as stand-alone systems or in conjunction with a ducted HVAC system or commercial air handlers.

Cigarette Smoke Removal

I have written over 100 articles and blogs on the subject of removing cigarette smoke and odor from any indoor environment and the resolutions we have today are the same as those proposed 30 years ago.

The best and most effective method of removing smoke from the indoor environment is to eliminate any smoking in indoor environments. It’s just that simple. Removing it using air filtration, air dilution, carbon filters and high volume fans is only a band-aid approach at best.

Once the cigarette smoke sticks to any surface it will re-release that odor for days. It requires a strong solvent based cleaner to remove the brown tar material that is present on the walls of a smoking environment.

Pure Air Systems has been around since 1985 producing high capacity, commercial grade, certified HEPA and Carbon based fan powered air filtration systems for the residential, commercial, institutional, medical and industrial market place. Many of these systems were sold for the exclusive purpose of removing cigarette and cigar smoke from indoor environments.

The degree of effectiveness of the systems was directly proportional to how much smoke we could remove at the source over time. And, the cigarette smoke will clog up a prefilter in two to three weeks and the HEPA filter in less than 3 months. The Carbon media in the units which is designed to remove much of the odor, would last perhaps 4 to 6 weeks at best. In essence, it is very expensive and difficult to remove the cigarette smoke and odor with any degree of effectiveness.

It is for this reason that smoking is prohibited from most buildings, hospitals, schools, airports, planes, trains and ships. Aside from the environmental issues smoking is also extremely harmful to your health.

Pure Air University

When evaluating a product for which you may have little knowledge it is always good to get some objective information from a reliable source. The company from which you want to purchase the product will have a lot of sales data and list the benefits and features but little about the technology used in the design and operation of the product.

The philosophy of many companies is to list features that people will recognize and not confuse them with the technical specifications.This allows for more reading space to sell the product and show the applications.

Selling air filtration systems can be challenging especially when you now have a standard that is used when rating the efficiency of the filters. The MERV ratings are used to provide the consumer with some idea of the overall effectiveness of the filters based on a percentage of removal of certain size particulate. The ratings start at 1 and go 20 with the higher numbers meaning better efficiency at removing smaller airborne particulate.

Most furnace filters are in the MERV 4 to MERV 7  ratings. These are general duty filters and they are good at taking out large particles with minimal air flow resistance. To remove a very high percent of those particles that are sub-micron in size and the most harmful you need a MERV 20 filter.

Pure Air Systems has an in-depth archive in their “Pure Air University” section that goes into depth on the technology behind air filtration, both mechanical and electronic. With this information you can better determine the type and size of air filter or filtration system required for your application or specific health issue.

HEPA Filters are rated MERV 20 and as shown in a MERV chart  and are the best mechanical filter for use in applications where sub-micron particulate needs to be removed. These units are used in medical, institutional, industrial, commercial and laboratory applications.

More Than A Feeling

It is often said that people don’t want to hear you complain about issues and things that bother you on a regular basis. With the ability to express your every thought using social media, your issues are now broadcast around the world. Yes, everyone wants to vent about something and everyone hopes someone else will jump on their complaint band wagon.

However, when we do have a legitimate issue, especially one pertaining to our health, we do want someone to take our complaint seriously and not reject it as another “boy who cried wolf” emotion.

For 31 years Pure Air Systems has been selling their HEPA based air filtration systems to a wide range of customers including medical, institutional, industrial and residential. A large number of residential customers suffer from allergies or respiratory dysfunctions brought on by ingesting sub-micron airborne allergens and various types of particulate matter. Because the airborne particles are too small to see with the naked eye, when someone in the house or office complained about their severe reactions to the environment most people disregarded their complaints and paid little attention.

But for allergy sufferers and those individuals who really have issues with airborne molds and other building generated airborne contaminants these issues are real and can cause significant long-term health issues. It is ironic the the particles that tend to be trapped in the lung linings and mucus membranes are too small to see yet cause much more damage than the larger, visible airborne particulate that are aspirated in then out again.

The ability for the commercial grade, scanned HEPA filters, rated at 99.99% efficiency, to remove over 97% of these small, sub-micron particles is the reason people continue to purchase the PAS units over other types of filtration devices or systems. With over 31 years of experience in this arena, Pure Air Systems has become a major supplier of high-end, high performance, fan powered HEPA filtration systems.

Reducing Odors In Your Home

Odors can trigger memories that are both pleasant and repulsive. You walk into your old school building and it has that same smell you remember as a young child and it instantly brings back memories of your days at that institution. You open up the trash can lid that is full of garbage and the odor instantly reminds you of the days you worked in landfill in the summer between college semester.Both odor are significant. One positive and one negative.

Our olfactory senses are more keen than our visual processes and smells and odors often affect us more than what we see.

In 1980 Pure Air Systems was formed to provide high performance, fan powered air filtration systems that would incorporate both HEPA filters and Carbon media. The HEPA filters remove a high percentage of sub-micron particulate and the carbon media removed a large percentage of odors and gaseous pollutants.

It is difficult to see any airborne particle that is smaller than 100 microns in size ( about the diameter of your hair) so it is often difficult to know if the HEPA system is actually working. If you suffer from allergies triggered by airborne pollen, ragweed, etc. and you notice that while you are in your air filtered living environment that you have fewer issues with your allergies then one can assume the filtration system is working. When you have specific odors in the house, be they animal, cooking or smoking odors, a significant reduction or removal of the odors is notice immediately upon entering that room or living environment.

The systems manufactured by Pure Air Systems can incorporate up to 60 lbs of granular activated carbon in replaceable 15 lb framed cartridges. The smaller unit can carry up to 30 lbs of carbon. These high density, high capacity systems can significantly reduce odors and gaseous pollutants in commercial, institutional, industrial, medical and residential applications.

Typically these carbon filters need to be changed on a 3 to 6 month basis depending upon the nature of the odor and the amount of time the systems are running. For most home applications 6 months is a good change out frequency. These systems can be attached to an existing, ducted HVAC system or used as stand-alone units. The variable speed ECM motors used in these systems allows for incremental control of the speed and air flow.

Hurricane Season

Living in Florida one realizes that along with being in paradise you have the occasional tropical storm along the coast lines of this peninsula. Hurricane season runs from June 1st through November 1st and there are numerous guesses as to how many Hurricanes will form and most importantly how many will hit the state.  The prognosticators are experts from around the globe and most times they get it wrong. Guessing is still …guessing.

When people purchase an air filtration system from Pure Air Systems, they know exactly what they are getting. The specifications on the website detailing the performance and design characteristics of the systems is exactly what you will get when the system is delivered.

It is unfortunate that people more often than not have a genuine lack of confidence when buying something for the first time or getting information from an unknown source that they hope is reliable. Perhaps this is why many people still like to shop locally where they know the owners of the businesses and can see the merchandise up close and personal.

Being in business for over 31 years does say something about PAS and their product line. While minimal improvements have been made, the high quality standards for components and performance remain the same. You can ask customers who purchased the systems 10 years ago what they think of the products and you will get the same answer. “They work very well.”

PAS uses true, certified, commercial grade HEPA filters in all their systems. These are scanned HEPA filters, rated at 99.99% at 0.3 microns and larger. The motors used in these fan powered systems  are ECM, variable speed rated at 120/240 volts, 50/60Hz allowing us to ship them anywhere in the world.

In 1985 when PAS was started there were a large number of companies that made HEPA based filtration systems. Most of them low volume with very little fan power. Today, PAS is one of the few US based companies that make HEPA systems with capacities up to 2,000 CFM and with the ability to use them in a wide variety of systems and industries.

RAMBO

Of all the roles played by Sylvester Salon, Rambo is probably my favorite. It is a mixture of his Rocky character…slow spoken with deep honesty in his eyes, and his Expendables character where killing and maiming are often done with some weird humor. And of course, he faces numerous bad guys and barely gets scratched. Or if he does he has amazing healing powers.

Some companies have this same character trait where they keep the best parts of their operations as they move forward with new technologies and marketing concepts. In this way the customers still feel like they are dealing with the same people even though the company logo, location and product design are changing.

Pure Air Systems started its operation in 1985 with the promise that they would produce the highest quality products and offer superior performance and exceptional customer service. Fast forward 31 years later and Pure Air Systems still makes the same great HEPA based, fan powered air filtration systems in North America and have added a few new products along the way.

The PAS line of HEPA and Carbon filters use the newer variable speed ECM motors that can be digitally controlled producing air volumes from 50 CFM to 2,000 CFM in one percent increments if necessary. These systems can even be designed to work in series with ducted HVAC systems.

These units are used in almost every application with the reduction/removal of airborne contaminants at sizes below 0.3 microns in size. In fact the newer scanned, certified HEPA filters can remove 99.99% of all particles 0.3 microns and larger, consistently.

PAS has units in the commercial, medical, agricultural, industrial, institutional, military and residential markets. Some of them are even operating on ocean going vessels. Used as stand-alone or connected to your heating/cooling/ventilation systems, the HEPA systems from PAS are the most effective method for airborne contaminant control.

High Speed Rail

The world has to move billions of people every day from one place to another and it does it via numerous modes of transportation. Car, truck, bus, bike, motorcycle, boat, plane, train and even camel. Other than planes, no other mode of transportation is as fast or efficient as high-speed rail.

Bullet trains are common place in Japan and some other parts of Asia. Moving at speed up to 300 miles per hour, people can make one hour trips that used to take 4 to 6 hours using vehicular modes of transport. In addition, these trains carry as many as 500 passengers making this a very effective method of moving a lot of people quickly with minimal energy used per passenger.

Speed is important in other businesses as well. Pure Air Systems has been delivering high-speed, high performance HEPA based, fan powered air filtration systems since 1985. The ability to move a large amount of air ( CFM ) to effectively remove harmful airborne contaminants separates the PAS systems from the rest of the filtering devices. With the ability to move up to 2,000 CFM at long distances, the PAS products are capable of being used in a wide range of applications in the residential, commercial, institutional, industrial, medical and military.

These all metal units use the ECM variable speed motors that are rate 120/240 v 50/60 Hz so they can be used anywhere in the world. And, they incorporate not only a 99.99% scanned, commercial grade HEPA, but also a dual layer prefilter and carbon media filter as standard components.

There is a significant move to making all the health care facilities safer and using more of a defensive posture to reduce the level of airborne pathogens, viruses, bacteria and other harmful sub-micron sized particles. PAS is playing a major part in assisting your local health care facilities by using our systems to provide for isolation rooms and areas to separate infected people from the general population. These systems also help to protect the health care workers.

Niche Markets Better

Working with entrepreneurs is interesting as many of their new ideas and concepts often fall into the ” variation on the same theme” category.  Meaning their idea is only slightly different than other in-place products or the concept is one that has limited potential. More often than not the product ideas are ones that can be fabricated from various types of plastics or composite materials, lending them to be made using injection molding or thermo-set molding.

Product concepts that are more complex and require a mixture of metal, plastic, electronics and motors are more likely to be successful as most of these types of products are made off-shore. Sad but true. The Asian countries can design, prototype, develop and insert products faster than most U. S. based companies.

Pure Air Systems has been making high performance, HEPA based, fan powered air filtration systems since 1985 and today is one of only a handful of companies around the world that produce high capacity HEPA units for both the commercial and residential markets.

These systems are all metal and use the latest state-of-the-art ECM variable speed, digitally controlled motors, commercial grade, scanned HEPA filters, carbon media and dual-layer ring panel filters. They come in various sizes and styles and range in air flow capacity from 50 CFM to 2,000 CFM. These units can be used either attached to existing HVAC units or as stand-alone systems.

The high cost of components make the PAS units more expensive to make but they are more powerful and have a much higher particle reduction efficiency that all of their competitors combined. While you can still purchase a portable HEPA unit for under $400.00 the base price of the small HPS Pure Air Systems portable starts at over $1,000.00.

In addition, there is more profit in this type of product than the small, injection molded me-to types of products. Yes, the cost of entry is higher with the PAS model, but there is also an annuity value to the products as all three filters have to be replaced regularly and customers can only purchase the filters through PAS.
