How To Identify True HEPA Filters

The term HEPA means High Performance Particulate Absolute or Air. This type of filter is used in many applications where the reduction and/or removal of fine, sub-micron airborne particles is required at a much higher efficiency than standard media filters like the ones used in air handling systems or HVAC systems. In order to qualify as a true, certified HEPA filter it must pass be able to have a rating equivalent to a MERV 17 or higher. This means the filter can capture 99.97% of all particles 0.3 microns or larger. Compare this to a MERV 5 or 6 filter which has an efficiency of less than 20% on particles larger than 10 microns in size.

A true HEPA filter is normally a pleated media filter with large pleats with separators or a mini-pleat with glue type separators and is enclosed in a metal housing.and is sealed with an industrial sealant. The metal housing has a gasket on one end of the housing which is normally placed on knife edge seal to eliminate any air bypassing the HEPA filter. The HEPA paper or filter media is fairly fragile and it also enclosed in a housing to protect the HEPA. 

Because HEPA filter paper is very dense, the ability to pull air through the HEPA requires a larger motor/blower assembly as the pressure drop or resistance as measured in inches of water is much higher than the resistance through a standard throw-away furnace filter.Usually HEPA filters are mated with a blower/motor that is designed for this type of media, or they are enclosed is a housing like the ones Pure Air Systems makes that are stand-alone units with their own blower/motor and prefilters.

Pure Air Systems, located in Indianapolis, Indiana is one of a few companies in the U.S. that makes a high performance, certified HEPA, fan powered air filtration system that can be use in the residential, commercial, institutional, industrial and medical markets. These systems are designed to either be attached to any HVAC system in a partial by-pass configuration or as stand-alone units. They range in air flow from 50 CFM to 2,000 CFM.

Climate Change Particulate Effect

Climate change is more than warming of the earth or oceans at an unprecedented rate, it is the change in atmospheric conditions that alter the environment in every way. In places where the usual amount of rain has been dramatically reduced, the levels of airborne dust particles is increasing. Walking on or driving on packed soil creates tiny sub-micron particles to be released into the air at a faster rate as there is less moisture to keep the soil intact upon impact.

These airborne particulate consist of both organic and inorganic materials some of which can be harmful when inhaled in small quantities over a long period of time. While our lungs can usually handle particles that are 10 microns or larger, the smaller particles tend to get trapped in the lung linings and mucus membranes and are slow to be released.

In 1985 Pure Air Systems was formed to produce and sell HEPA based air filtration systems for the residential market. In the past 30 years, PAS has grown from one system to seven and now provides true, commercial grade, HEPA systems to the commercial, institutional, industrial, medical and residential markets and sells its’ systems all over the world.

While homes and buildings have developed a much better process to keep them close to air tight, the higher levels of sub-micron particulate are still present in the buildings. More importantly, these particulate are at very high concentrations when the air is stagnant or on hot, dry days. The PAS HEPA systems have proven themselves to be  extremely effective at removing 99.99% of all particles 0.3 microns or larger and close to 99% of smaller particles.

Extreme weather produces extreme environmental conditions and it is important to understand the relationship especially if you live out west in the dryer climates.

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.

Why HEPA Filtration Is The Best

HEPA filters are designed to remove a very high percentage; more than 99.97%, of all particles 0.3 microns in size or larger. In truth they are actually more efficient than that as they become dirty they actually increase in efficiency. This is true of most mechanical filters but HEPA media starts out at an efficiency that is higher than the general duty filters that you use in your HVAC systems after they are fully loaded.

HEPA filters are the ONLY filters used in Hospital Surgery Suites, Clean Rooms, the CDC and any application where the the removal of sub-micron particulate is an absolute necessity. You would be in serious trouble if you have your body was opened up in an environment such as you bedroom. Even if you think it is clean, it is not. Airborne pathogens are a constant cause for infection and having surgery in anything but a 100% HEPA filtered room is asking for trouble.

While HEPA filters are extremely effective in trapping sub-micron sized particles, they are also extremely dense and have a fair amount of air-flow restriction. As a result, larger, more powerful motors and specially designed fans are required to pull the air through the HEPA filter. And, as the HEPA loads up the fan motors must be able to increase in speed to make up for the air flow volume loss that takes place as the HEPA becomes dirty.

Because HEPA filter media ( wet laid HEPA paper ) is so dense it will load up very quickly, a pre-filter media is required in front of the HEPA filter to capture as much of the larger particles as possible and only allow the very small, sub-micron particles to enter the HEPA filter. Without the use of a pre-filter a HEPA filter could load up in a few days and make the HEPA useless.

HEPA filters are available for use in the residential markets through companies such as Pure Air Systems out of Indianapolis, IN. In business since 1985, PAS is the leader in fan-powered HEPA based air filtration systems and they range in capacity from 50 CFM to 2000 CFM. These metal housed units also use variable speed drive motors  ( ECM ) that are rated 120/240 50/60 Hz so they can be used anywhere in the world.

Fool Britania

Just when you thought people were actually getting to understand the concept of Global Partnerships, the Britt’s decide to go backwards a couple of centuries and again become an Island of economic isolation.

Yes the world is changing and yes it is moving in a direction that is making the old guard nervous but progress in many forms always offers challenges as well as new horizons. For some reason the older generation is clinging feverishly to the past and acting out of fear rather than recognizing that change is a natural part of the death of a generation.

Making decisions based on supposition supported by no facts is the quickest way to fall off a cliff. A very high cliff. And, it is often followed by regrets. Unfortunately the speed of falling is too fast to be saved by the net of regrets.

Pure Air Systems makes some of the best HEPA based air filtration systems in the U.S. Making decisions to move or not move forward with new equipment designs was never based on what happened in the past, but what we thought would transpire in the future. It is always a risk to make changes to a very stable and well-liked product platform but if the customer liked you yesterday more than likely, even though the new product may look very different, the loyalty for your company will sustain you through the new product transition. That is as long as the performance of the former is the same or better than the latter.

Companies like Uber, AirBnb, Lyst and all the main and new social media programs that blast through our digital, mobile devices have forever changed the way companies make money. Yes, these are geared toward the new generation, and no, senior citizens still want to keep their hard wire phones. So there is a major split in direction. Yet, this has happened many times before in the growth of our county and the pain of change has always been removed by the addition of new job opportunities.

Pure Air Systems has been more about change and less about the status quo. For more information on our complete product line go to our website at: https://www.pureairsystems.com  or call us on our toll-free number at: 800-869-8025.

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.

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.

Patience Pays Off

Coming into our 31st year of operation, Pure Air Systems HEPA based air filtration systems are the best and one of the only choices for high performance, fan powered, commercial grade HEPA filtration systems.

Today in the U.S., PAS is perhaps the only company that continues to manufacture HEPA systems that are powerful enough to move up to 2000 CFM of air through a commercial grade, 99.99% scanned HEPA filter and maintain that air flow even as the HEPA filter becomes more restrictive as it loads up.

Of course there are small, plastic housed, quasi-HEPA units on the market that move up to 150 CFM ( rated but not tested ) and they sell for less than $300.00. They are, however, not really capable of moving enough air even in a small room to adequately remove the level of airborne contaminants that may be creating some respiratory or other health issues for the occupants.

Because of the high grade fabrication using all metal housings, blowers and the newer ECM variable speed motors. the 7 different units have a long history of long life. Beginning in 1985, some of the units produced in the late 80’s and early 90’s are still in operation today. All they need are replacement filters which are easily obtained from PAS.

The seven different systems offer air volume capacities from as low as 50 CFM to 2000 CFM with incremental volume controls for all the units. All of the systems also come with Carbon media and when required, the HEPA unit can be removed and replaced with Carbon making the system an gas or odor removal unit for other applications.

Looking Down The Rabbit Hole

When Alice followed the Rabbit down the hole she never expected to enter a world of fantasy and terror. One would not think twice about following a rabbit as these creatures are afraid of humans and are not dangerous in the least. So her instincts were correct, at least in her initial phase of thought.

Often we find ourselves doing the same thing when we follow or pay attention to something that is benign but turns out to be a very bad decision. This is true with individuals and companies we follow trusting them and their products or services to give us what we expect and are willing to follow through when we have an issue or challenge with them or their operations.

When prospective customers searching for a better performing air filtration system, they were often lead to the boys at Pure Air Systems. PAS has been a very successful air filtration manufacturer that uses only high end, commercial grade HEPA based filters for its mult-filter, fan powered systems. So when customers made their first purchase of a PAS unit they expected to get the performance and reliability that was the hallmark of these units. Unlike Alice’s experience with the rabbit hole Pure Air Systems customers found the sought after pot of gold at the end of the rainbow.

For over 30 years PAS has been providing the best performing, highest quality HEPA based air filtration systems in North America. With thousands sold all over the world, Pure Air Systems has been setting the standards for fan powered, mult-filter units. Many of their systems that were sold in the 80′ are still in operation today. Even Alice would be happy to follow the PAS rabbit.

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.
