HEPA Type Filters Are Not True HEPA Filters

For the uninitiated, HEPA is an acronym for High Efficiency Particulate Air or Absolute. For many years these types of filters were called “absolute” filters because they basically captured absolutely all airborne particles that came in contact with the filter media.

HEPA filters are made from a special wet-laid material that has glass fibers as the basic material. It is then smoothed out like the making of paper and that is why the material is referred to as HEPA paper. It is also very fragile and can be cut or torn very easily.

HEPA filters have to meet a very stringent set of requirements before they can be labeled a true HEPA filter. They must be able to remove a minimum of 99.97% of all particles 0.3 microns or larger with a high efficiency below the 0.3 threshold. The media pack has to be sealed in a metal or aluminum frame and have a gasket on the downstream side to ensure complete sealing between the filter and the box or device in which it is placed.

HEPA filters are expensive. Very expensive and some of the new, higher efficiency filters like the ULPA or SULPA HEPA filters which are used in clean room applications and micro-chip manufacturing are 2 to 3 times more expensive than standard HEPA filters.

HEPA Type Filters are called that by competitors that don’t make true HEPA filters. These are filters that have a high MERV ratings. HEPA filters have a MERV rating of 20 while HEPA type filters have a MERV rating of 15. The difference is very big especially when you are talking about the removal of bacteria and viruses which is what true HEPA filters remove.

Pure Air Systems has been making HEPA based, fan powered air filtration systems since 1985. They use only true HEPA filters in their series of seven different air filtration devices.

Isolation Room

Isolation is a word that means to separate from or detach from another area in all aspects. Isolation rooms are used often in the medical market to maintain a safe environment from the general public by isolating a dangerous or highly communicable diseased patient from the the general population.

Isolation is more than just separation by walls and doors. In the realm of airborne viruses you require a special filtration method to ensure that any air that is passed between the isolation room and the outside world is properly filtered. This is always done using HEPA based air filtration systems to remove even the smallest airborne particles to eliminate the possible transmission of deadly diseases.

Pure Air Systems has been providing commercial grade, certified HEPA and ULPA filters for a wide range of applications and markets since 1985. HEPA filters have been the only true mechanical filter type that has the ability to absolutely trap the airborne allergens and pathogens that are associated with creating serious illnesses and health issues since the early 1980’s.

Pure Air Systems also makes HEPA systems that can be used in the residential, institutional, commercial, industrial and military markets. After 32 years of being in business Pure Air Systems has well over 10,000 units in the field in both the US and overseas.

Seven different models are available from fan powered air volumes starting at 50 CFM to 2,000 CFM. All the systems use the new variable speed drive motors and they are all rated at, 120/240 volt, 50/60 Hz so they can be used anywhere in the world.

The all metal housings and commercial grade components ensure that these systems will provide high performance service over very long periods of time.  For more information on the complete line of HEPA and Carbon based systems, please go to our website at: http://www.pureairsystems.com  or call us on our toll-free number at: 800-869-8025.

Obsession

Having been an owner of a company that produced actual hard technologies and not just a service or digital technology process I have been obsessed with finding a way to help people understand the value of making something of value and making a living at it.

Pure Air Systems was started in 1985 with one air filtration system in our product line. We had adapted a commercial HEPA filtration system that was used in the Asbestos Abatement Industry to work with any ducted HVAC system be it residential or commercial. In addition we modified it to work as a stand-alone unit for any application requiring the reduction or removal of sub-micron airborne contaminants.

The acceptance of the product by consumers and commercial operations was gratifying but we soon realized that our original model 600H unit ( producing 600 CFM of HEPA filtered air) was not adequate for many of the commercial customers applications.

To resolve this issue we decided to bring two new HEPA filter systems into the product mix. One rated at 1200 CFM and the largest rated at 2,000 CFM. We were able to adapt the same size blower and housing for both air flows by simply adding a 3/4 HP motor to the 1200 HS unit and a 1 HP motor to the 2000HS unit. In this way customers could actually increase the capacity of their 1200HS ( should they need it ) to 2000 CFM. This was both cost effective and made it easier in the manufacturing end.

The other issue presented to us was the configuration of the filter housing itself. We had originally designed the units so they were built in two sections that were symmetrical giving us the ability to orient the inlet and discharge of the units to adapt to any type of HVAC system. We then added another modification to allow for any of our systems to have either a straight through air flow from end to end or a top inlet and side discharge. These housings could even by changed in the field should the customer realize one orientation was better than the other.

Being obsessed with making the systems customer friendly was always my goal. Pure Air Systems is now 31 years old and the obsession with maintaining high performance HEPA based air filtration systems is still a priority.

Alternate Concepts

Change is difficult; change for many is impossible. When you put your pants on you usually put one leg in before the other.For some it is the right, others the left. This is usually an automatic process. Tomorrow put the other leg in first and see how much that changes your balance and how difficult it is to make that simple change. Yes, as much as we think we are open minded, most of us follow the same paths and (false) truths all of the time.

Studies have shown that when an individual is shown factual, undisputed evidence that does NOT support one of their specific beliefs, 95% of the people won’t accept the new, factual information and would prefer to keep their own wrong beliefs.

This phenomenon is one reason why many people resist changing political parties or religions or even social organization associations. Even if they feel uncomfortable about the process and discussion points made by other members of the group. Their fear of not being accepted by their peers trumps their ability to challenge any issue or individual.

In 1985, Pure Air Systems started their company to offer the best HEPA based, fan powered air filtration systems on the market. They went against the norm of using electronic air cleaners or ozone generators as the standard for airborne contaminant control. HEPA filters were also extremely expensive and were only used in the commercial and electronics industry. Many individuals and HVAC contractors resisted even trying the units as they were locked into the older style of filtration.

Fast forward to 2016. Today, the line of PAS HEPA units is now considered some of the best HEPA based filter systems in North America. Their continued success with new models and the high performance and quality of construction moved the non-believers to buyers and eventually the market for PAS products increased significantly.

Moving Toward Tomorrow

When we think about the future we often take a lot of the present and some of the past with us on this journey. Even though we know there are rapid changes in technology buzzing past us like a swarm of bees, we still have a tendency to look at the future wrapped around by our past. Fear of change and fear of the unknown continue to hold many of us back from taking chances or risks on new ventures or ideas because we fear we may fail. Yet, all of the innovations in science and technology were accomplished knowing that success can only come when it is accompanied by trial and error.

Companies that are looking to develop new products or enhancements to existing equipment are often faced with the reality that competition is now global and the amount of new technologies and process that are available to everyone really levels out the playing field. With many of the U.S. based corporations having their R&D operations in their overseas facilities the ability to adapt new technologies and develop new products is challenging for a large number of U.S. based corporations. Only the smaller, more versatile companies have the ability and in-house skills to create new products but require more time to bring them to market.

Pure Air Systems, Inc., an Indiana based corporation, has been designing and manufacturing commercial grade, high performance HEPA based air filtration systems since 1985. For over 32 years PAS has been developing new products to bring to their ever-changing customer base to ensure their existence in the market. In addition, PAS continued to build their systems using only the highest grade components and variable speed motor technology.

Over the years some of their competitors have dropped out of the market leaving Pure Air Systems as one of the only companies in the US that makes this high volume, high performance, industrial grade HEPA systems on the market. There are other HEPA units but the vast majority are small, low powered, low volume systems that are often made from plastic and not steel like the PAS units.

Going forward, PAS is continuing to look at new market opportunities and developing new systems to meet the demands and performance requirements including designing new enclosures for some of the larger 3D Printing machines that are making their mark in the market today. Look for more new concepts from Pure Air Systems in the very near future.

Technology Does Matter

It seems as though some people think that technology is over taking our lives and that not everything we do is based on technology.  In truth, technology impacts almost every  aspect of our lives in one way or another. And, yes almost everything we do has some type of higher technology attached to it. And technology will continue to impact our lives in ways we can not yet comprehend.

Technology is not only impacting the way we communicate, drive, vacation, travel, work, entertain and cook but our health care systems and the military. It is the reason why the US is effectively competing with the rest of the world as technology continues to make the world smaller and smaller.

In 1985 Pure Air Systems opened its doors with a new fan powered air filtration system using the new filter technology, HEPA filtration. Actually HEPA filters were developed in 1941 but the use of HEPA filters in the general air cleaner market did not take place until the early 80’s.  HEPA filters are specifically designed and manufactured to remove a very large percentage of extremely small, sub-micron, airborne particles with an amazing efficiency. HEPA filters are also very expensive as compared to a regular furnace filter. About 40 times more expensive.

HEPA filters are a critical part of all the clean rooms where micro-chips are manufactured; they are the main filter in surgery rooms, optical glass manufacturing, isolation rooms, laboratories, bacterial and virus labs, the CDC, and any place where the removal of airborne pathogens and allergens is required.

HEPA filters are now a standard part of vacuum cleaners and many portable filtration systems and even packaging and food process systems. They are also available to the general public incorporated in systems like the seven different units available from Pure Air Systems. This technology is essential for these and many other applications in many other industries around the globe.

Build Platform

I spend a lot of my time designing objects with 3D modeling software and printing on one of my 4 3D printers. There are a lot of FFF (fused filament fabrication) 3D printers on the market and we have two with large build platforms approximately 12″ x 12″ square. We can also print an object up to 10″ tall.

In the land of 3D Printers “size matters” very much. As more prototyping is being done on 3D printers the larger the build area the more effective they become in making large parts or objects in one print rather than scaling the object down or printing out separate pieces of the object.

The manufacturing business model is much like 3D printing model. You have to create a workable object, product or pieces and then be able to produce in using the fewest number of parts. The larger the production area the greater the efficiency to produce larger parts or assemblies.

Pure Air Systems, Inc. started their business making commercial grade HEPA, fan powered air filtration systems back in 1985 and working out of a garage. There was little room for component parts and filters so much of the assembly was done using outside contractors. While this worked for a while, as the business grew, PAS required more space to start work on prototyping larger systems for their growing commercial business.

By 1998 PAS was moving into a 9,000 sq. ft. building with enough room to stock all the components for its then seven model HEPA systems. The extra space also allowed for more efficient assembly and faster turn out of products. In addition, all of the replacement filters could be stored in the facility so spare filters, parts and units could be shipped from one location usually in one to three days.

As 3D Printing continues to innovate itself almost weekly adding faster printers, larger build platforms and the use of newer, stronger filament materials, it is possible that Pure Air Systems may eventually move into 3D printing or Additive Manufacturing as it is now called, for the production of some of its components. Size does matter.

Z Gap

Using 3D Printers has been a practice of mine for the past two years and I have learned a lot about the technology and the capabilities of this new process. For the under $3,000.00 range, the printers are fairly simple to operate and many of then can now print in over 25 different materials and not just plastics. We can print in brass, bronze, copper, wood, ceramic, nylon, conductive, magnetic, flexible, poly carbonate, carbon fiber and the new graphene materials.  It seems every day a new material is added to the list.

Of course there are other types of printers, those that use resin or powder and some can print with metal. These are the high end printers that range from $15,000.00 to over $500.000.00. But those machines are getting less expensive so maybe in two years they will be under $20,000.00 and available for small business operations. In the meantime we use the more common printers.

The Z gap is the distance from the bottom of the printing nozzle to the surface of the build platform. For most machines this setting in done manually and it is a little challenging to get that distance set just right. It takes practice and patience and is critical to the overall finish of the end product.

Pure Air Systems has been manufacturing HEPA and Carbon based, fan powered, commercial grade systems since 1985 and has learned how to set the gap between price, performance, execution and customer need. It is always a balancing game when you are trying to look at the needs of the customer and the bottom line of the business. Many times you purchase another one of a product you purchased years ago only to find out the next version is not made as well and has a reduced performance and life compared to the original. This is often the case when a small, family run, operation is purchased by a larger, publicly held company. The gap is often compromised in favor of the bottom line and not the customer.

PAS has been around for 30 years because it knows the value of keeping their customers happy and providing a consistently well engineered systems that continue to meet or exceed the needs of their customers.

Chrysis

Aside from writing blogs I am also a fan of new technologies like Nanotechnology and OLED technology. In fact a blog/novella I am writing incorporates these two scientific advances.  In addition, I am also a closet XBox game player…mostly of the first shooter variety. I have played and completed the entire Halo series of games and now have embarked on a new journey with the popular franchise game “Chrysis.”  The Chrysis character has a Nano suit that allows him to create certain defensive postures. He can make himself invisible by turning on the “Cloaking” device or repel bullets and other weapons by switching to “Nano Armor.” With the advances in Nanotechnology today the reality of wearing this type of suit is much more science faction than science fiction. Since we will have to wait a while before this type of protective clothing is available we continue to rely on best practices to avoid the elements of life that can do us harm.

We live and breathe in an environmental soup of sorts. Inside homes, buildings, schools, hospitals, libraries, etc. ,etc, we have hundreds of airborne contaminants floating across our noses and mouths as we take in that next breath of life-giving air. Unfortunately that breath of air can contain thousands of sub-micron organisms and particulates that, over time, can create some significant health issues. Out doors in the towns and cities we have a wide range of airborne contaminants to deal with such as; carbon monoxide and nitrous oxide from car exhausts, particulate effluents from factories and other industrial sources. And, we have our sun. The sun gives us light, heat, warmth, vitamin D and the preceding letter in the alphabet,  C, as in Cancer. Yes, a Nano suit would be a nice option.

Pure Air Systems has  been manufacturing commercial grade HEPA air filtration systems since 1985. HEPA filters are the most effective mechanical devices for removal and/or reduction of the small, sub-micron particles that can be harmful to the human body. In addition, the PAS systems also incorporate Carbon media filters to adsorb harmful odors and gaesous pollutants that can create severe respiratory health issues. These systems come in a variety of capacities ( CFM ) and configurations designed to fit any commercial, industrial, institutional, medical or residential need.

When properly used and configured, the PAS HEPA systems can provide for a near-clean room environment. This feature provides for better, safer and healthier work and living environments and is as close to a Nano suit that you can currently purchase. And, while the PAS systems can’t protect you from the outdoor environment, they can at least give you 8 to 12 hours of protection in the comfort of your home.

Performance VS Price For HEPA Air Filtration Systems

The acronym HEPA stands for “High Efficiency Particulate Absolute” filter. The word absolute means just that. A HEPA filter by standards means it will capture, initially, 99.97% of all particles 0.3 microns in diameter or larger. This means if you had 10,000 particles in that size range and put them through the HEPA filter only 3 are allowed to pass through the media. There are scanned HEPA filters which have a minimum efficiency of 99.99% at 0.3 microns, ULPA filters with minimum efficiency of 99.9995% at 0.12 microns and SULPA filters with minimum efficiency of 99.99999% at 0.12 microns. In every case the overall efficiency of the filters is directly proportional to how the filter in sealed, or contained in the holding frame or air filtration device.

There are a number of small, portable style HEPA filtration systems sold on the market today. The majority of them are designed for residential applications; specifically bedrooms and small living areas. These systems have very small fans and can only move about 50 to 200 CFM of filtered air and have HEPA filters that are not necessarily sealed tightly in their housings. Then there are fewer than 5 portable type HEPA units that are designed to be used in the commercial markets where optimum performance is required. When we get to the larger, stand-alone HEPA filtration systems, those that can move from 100 to 2,000 CFM of filtered air, there are only two companies in that arena.

HEPA filters are expensive. They requires very special equipment to manufacture them and highly sophisticated, expensive test equipment to certify them and ensure they meet all the regulations and standards that allow them to be certified as HEPA filters. They are usually framed in aluminum or steel and have a gasket on one side to allow for compression sealing in their prospective housings. Unless the HEPA filter is completely sealed, air will by-pass around the filter and render the HEPA filter useless.

Companies and individuals purchase HEPA filtration systems to perform a certain function; removal of harmful airborne sub-micron particulate. The airborne particles may be allergens, pathogens, dust and dirt particles or particles from a manufacturing operation. In almost every case, the performance of the equipment is tantamount to the price of the systems. Since the lack of performance is directly proportional to the overall efficiency of the specific operation, the inability of the HEPA systems to perform can cost hundreds of times more than the equipment itself.

Pure Air Systems has been manufacturing commercial grade, certified HEPA based air filtration systems since 1985 and its systems are considered one of the premier units on the market today. The fact that PAS has been in operation for over 27 years is a testament to their ability to meet or exceed the expectations of their customers. The medical, commercial, institutional, environmental, military and industrial markets all look to PAS to help them solve their critical airborne particulate problems. Performance is their primary concern.
