In 1985 Pure Air Systems was founded to produce true HEPA filtration systems for the residential, commercial, institutional, medical and industrial markets. The first HEPA system, the model 600H, was 16″ x16″ x 34″ high and weighed 97 lbs. That unit is still made today under the new name 600HS.

Over the years PAS made larger units to handle larger areas and applications and also develoed a smaller portable HEPA unit that is 13″ x  13″ x 21″ long and weighs 30lbs. There are now two versions of that large, portable unit.

In 2018 PAS embarked on an R&D project to develop a small, in-car true HEPA unit that also included a combination prefilter/carbon media wrap. The round HEPA filter is rated at 99.99% at 0.3 microns and will remove particles as small as 0.12 microns. The carbon will remove odors and the prefilter removes the larger particles keeping the HEPA to remove only the sub-micron particulates.

The CAR HEPA prototype is 5.5″ square and 7″ long. It weighs approximately 3 lbs and uses a small, whisper quiet fan that runs off the 12 volt plug ( or USB) in your car. PAS is also in the process of developing a HEPA Holder so you can mount you HEPA in a stratgic location for best air filtration results.

While some very high end cars ( Tesla, Mercedes and some BMW) have high efficiency cabin air filtration, most vehicles have little or none. The CAR HEPA unit will significantly reduce the levels of harmful, sub-micron particulates. These particles include bacteria, airborne allergens and some viruses.

In order to speed up the development process PAS is utilizing 3D Modeling and 3D Printing to create the housing for the unit. The first iteration took just one week to develop and now some tweaking of the housing size is in the works. It may be that the CAR HEPA will be produced on 3D Printers and they could be individualized or personalized with your name and choice of colors.

For those people who live and work in colder climates, the amount of time you spend indoors is proportionally more than those individuals who live in warmer climates. In addition colder air is much drier than warm moist air and as a result dust particles and other airborne contaminants tend to stay suspended in air for much longer periods of time.

As humans we inhale large quantities of air every time we take a breath. All of that air is filtered through our mucus membranes and lung linings and a large portion of the particulate are ( those particles larger than 20 microns ) air filtered out and most often projected out of the body when exhaling.

The smaller particles, those under 20 microns and especially those sub-micron particles, are trapped in the lung linings and not exhaled. They are absorbed by the body and then flushed out of the body. However, some of those particulate may be harmful to the body and these may be airborne viruses or bacteria or perhaps some other type of airborne contaminant. Collecting these particulate is what Pure Air Systems does with their HEPA based air filtration systems.

Started in 1985, Pure Air Systems created a line of Air Filters that specifically used true, commercial grade, scanned HEPA filters in all their systems. HEPA filters are the most effective mechanical device for removing 99.99% of all particles 0.3 microns or lager and approaching 99.98% at particles as small as 0.12 microns in size.

These HEPA systems are all fan powered and use the newer ECM variable speed drive motors so they can be used on 120/240 volt 50/60Hz electrical systems and used any where in the world.

The systems range in capacity from 50 CFM ( Cubic Foot Per Minute) up to 2,000 CFM. They can be used either attached to an existing ducted HVAC system in the by-pass configuration or as stand-alone units. These Air Filtration systems can be used in residential, commercial, institutional, medical and industrial applications.

Pure Air Systems is now 32 years old and is one of the remaining few companies in North America that still makes high end, commercial grade, fan powered HEPA air filtration systems. These systems are designed to provide true HEPA filtered air in a wide variety of applications including but not limited to: commercial, industrial, institutional, medical and residential.

Pure Air Systems makes only one type of HEPA based air filtration system so the residential customer receives the same identical system as the hospital or laboratory. These systems are designed to last a long time and run for years with minimal maintenance other than changing any one of the three filters at regular intervals.

There are a number of models available designed to fit any application and with the ability to be either installed as stand-alone units or being attached to the return air side of any HVAC system; commercial or residential.

Pure Air Systems is now the Air Apparent in this industry as there is only one other company in Europe that makes fan powered HEPA air filtration systems with the ability to handle air flows from less than 50 CFM up to 2000 CFM in a small housing configuration. In addition, the PAS units utilize the newer ECM variable speed drive motors that are rated 120/240 volt 50/6 Hz motors so they can be used anywhere in the world.

Each system has a prefilter, carbon media filter and true HEPA  filter. The systems can be configured to have all Carbon media with one prefilter for applications where only odors and gases are present. Or, they can be configured with two prefilters for applications where high levels of large particulate are present.

Our company has been around since 1985 and over the past 32 years we have seen some interesting changes in technology and the way we communicate with each other and the world. It is in the communication department that we see major changes.

PAS first had a URL in 1995. There were few ways to promote  yourself in those days and we thought being part of the Internet would be a great way to promote our products and company. Turns our we were correct.

Today, almost 80% of all our new customer leads come through our website. People can view our equipment and learn more about our products and systems and the applications for all of them and how they can be installed. But we need to go further.

Our current site is now over 6 years old and needs some fine tuning . It is not responsive so it is somewhat difficult to view on a mobile device. And since over 60% of our new views are from phones or tablets we need to change that. Also we will make the site more user friendly and eliminate some of the confusion about the differences between commercial systems and residential systems ( clue…there are none ).

We would also like to add a Chat app and be more progressive in using Facebook and Twitter. These social media platforms have become the best way to connect to everyone anywhere at anytime.

Look for a major face-lift on our site coming in February of 2018. We think you will like it a lot.

By now we all know that the Zombie Apocalypse was created through a virus developed by some unknown group. You also know by watching the documentary, Walking Dead, that the only way to put down a Zombie for good is to shoot or stab them or remove their head. So if you want to be a Zombie killer and not a member of the walking dead, then you need to pay attention to the rest of this blog. It may save your life!

Since we now know that an airborne virus is the method by which we become infected, the the obvious solution is to not breath in any contaminated air. Hard to do when the infected are now everywhere. But there is a solution. HEPA air filtration.

Started in 1985, Pure Air Systems introduced a commercial grade, fan powered HEPA air filtration system for use in homes, hospitals, schools, office buildings and other commercial facilities. Had all of these potential customers heeded our warning and installed one of our 7 different HEPA filtration models we may have to be writing about this issue today.

The HEPA systems handle up to 2,000 cubic feet of air per minute and can provide a surgery suite/clean room environment in any structure, even your home where you can hide comfortably from the Zombies.

HEPA filters are the only filtration method of significantly removing or reducing the levels of airborne contaminants at an efficiency of 99.99% at 0.3 microns and larger. They are even effective down to 0.12 microns and smaller ( virus size ) and become more efficient over time. …You are already thinking you need one aren’t you?

So, making the decision to buy one of our HEPA filtration systems is a “no brainer” if you get my drift.

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.

The process of removing airborne contaminants that are small enough to potentially cause respiratory dysfunctions is somewhat challenging. For the most part particulate removal with standard air furnace type filters is effective on larger, visible particles many of which are aspirated in and then expelled out of the lung systems.

Sub-micron sized particles, those that are less than 1 micron in size, are easily aspirated into the lungs and much of this particulate will stay logged in the lung linings or mucus membranes. This is why particulate removal with HEPA filters is so necessary especially in where airborne allergens and harmful bacteria and viruses are present.

Originally designed during the development of the Atomic Bomb in Los Alamos, New Mexico, HEPA filters have progressed to include filter medias that are more effective than the 99.97% at 0.3 microns. Today there are SULPA filters that have an efficiency of 99.99995% at 0.12 microns. These are the types of filters used in Class 10 clean rooms where micro-chips are manufactured.

Pure Air Systems began using HEPA filters for particulate removal in 1985 in their first system, the Model 600H. This fan powered HEPA based air filtration system could move up to 600 CFM of HEPA filtered air. Today, PAS makes 6 other HEPA based models including a portable HEPA unit capable of moving from 10 CFM to 250 CFM using the newer ECM motors. The largest system, Model 2000HS Plus moves up to 2,000 CFM of HEPA filtered air.

Over 70 years ago the HEPA filter was born to protect the technicians from beta particles produced during the design of the bomb. Today, particulate removal with HEPA filters is considered the best method for protecting us from harmful airborne contaminants.

There is a lot of discussion these days about historical monuments and the issue of whether they should remain or be moved or destroyed. No matter which side you choose the fact remains that these were built for a specific purpose in their time. Many are still standing and a number are now gone.

Many corporations started out creating products that were relevant for their time in the development of our country and it’s industrial base. Over time, many of those companies have either changed completely, went out of business or merged with another larger corporation. Time changes everything.

Pure Air Systems started in 1985 by offering its’ first HEPA based, fan powered air filtration system. At the time it was slightly ahead of the curve as this type of high-end filtration system began to set the standards for high-performance in the area of reduction and/or removal of large percentages of harmful, airborne sub-micron particulate.

Over time, Pure Air Systems saw the opportunity to add larger systems with more airflow capabilities to its product line and began to expand its systems into the commercial, institutional, medical and industrial markets. The addition of the new ECM variable speed motors in 1999 added a new dimension to their product line.

The variable speed motors were magnet driven as apposed to the traditional use of wound motors thus giving PAS the ability to use digital controllers which allowed them to control the airflow in 1% increments. In addition, the motors were rated 120/240 v 50/60 Hz so they could be used anywhere in the world. This propelled the PAS line into another level which lead to the addition of 3 more products to their line.

If PAS was a monument it would probably look slightly different today, 32 years later, than the original built in 1985. Everything changes, nothing remains the same. Technology will move forward in spite of our attempts to slow it down. Time changes everything.

Life Insurance has many advantages especially if your dependents are on the receiving end of the payout. For you, not so much since your demise benefits other people.

Insurance is designed to cover risk. If you don’t believe that life has risks then don’t get insurance. However, your state requires you have insurance to drive and not having insurance on your home takes real guts…and a large bank account.

This leads us into the discussion of how best to insure ones self with minimal costs and maximum benefits. I am talking about insuring your health. Obviously seeing a Doctor on a regular basis and eating healthy and exercise do matter, but breathing good, clean, pollution free air is also very important.

Pure Air Systems started its business in 1985 selling one of the first true, commercial grade HEPA air filtration systems in the U.S. Beginning with one model over time, PAS developed 6 additional systems over the next decade and today, 32 years after it started, is now one of the major players in the world of HEPA air filtration systems.

These units are designed to be used in residential, commercial, industrial, institutional and medical applications. PAS was the first and is still the only company to apply a large, fan powered HEPA system to any forced air ducted HVAC system in the residential market. Customers who have installed these systems have seen dramatic results in reduction and / or removal of airborne contaminants that can cause severe respiratory dysfunctions.

In addition, the use of the PAS HEPA systems has propelled the companies products into markets all over the world. The use of the variable speed ECM motors in all the units allows them to be used in any country as they can operate on 120/240 50/60Hz electrical systems.

When one sees the word by-pass they often think of heart by-pass surgery or using the business by-pass around a city center.

Pure Air Systems pioneered the use of commercial grade, fan powered, HEPA filtration systems by-pass configurations in the  late 1980’s. Up until that time incorporating a true HEPA filtration system in a residential environment.

Most homes in the U.S. use a ducted heating/cooling systems where the air handler ( air moving device) is located in a basement, garage or closet. Putting anything other than a general duty low efficiency air filter in the return air side of the air handler is not recommended. The high pressure drop or resistance across more efficient filters and especially HEPA filters will significantly reduce the air flow through the air handler and could even have the cooling coils freeze up and/or increase your heating/cooling bills by up to 50%.

PAS came up the the concept of placing their 600HS or larger units in a configuration where some of the air coming back through the main return would be directed into the Hepa Shield system and the balance back to the air handler. Since the HEPA unit has its own blower/motor system this fan pulls the air through the HEPA eliminating any additional resistance that the main air handler blower/motor has to handle. In essence it is a 0 sum addition.

Even though only about 40 to 60 % of the air is going through the HEPA filter system at any one time, over the course of 24 hours all the air in the house has been completed filtered 25 to 50 times. And, if you have a home that is slightly negative then you can introduce a very small amount of outside air into the HEPA unit. A small amount, 50 to 100 CFM , is not going to affect the heating/cooling capabilities at all.

So, with one Pure Air Filtration system, you can create an extremely clean, environment that will significantly reduce airborne allergens, dust and because the systems also incorporated carbon filters, you will reduce house hold odors.
