The Price You Pay For Performance

Amazon and other online stores have created a scenario where people look at items that seem to be similar with various pricing. This has led people to believe that all products are similar and price becomes the deciding factor. For the manufacturers of these products it is difficult to up sell the their products. People will typically go to the best priced selection and read some reviews then make their choice. It is for this reason that many of the companies that make high-end products or products with proven superior performance elect not to market their products on Amazon and other similar online websites. They, instead, market them on their own websites.

So, for the astute buyer, often times you are better served to purchase the products from your selected company product website. They may charge a little more and often don’t offer free shipping, but their products are usually far superior and will last and perform better than many of those lesser expensive copies from your favorite online store.

Pure Air Systems has been offering their products online since 1990. Their commercial grade, fan-powered HEPA air filtration systems are some of the best in the world. With an average operating time of 15 to 20 years, these made in the US systems perform as advertised and the service from PAS is second to none.

AI, Becoming The Next Great Employee

I have been playing around with the new Google AI app, Bard. It is fast, and easy to use. Further more, it will create anything you ask it to create. The more and better the prompt information you input, the better the end result. I have already used it to write some simple contracts. 

In the field of engineering, AI apps are helping entrepreneurs and manufacturing and design companies to both enhance existing designs and fabrication techniques but also developing whole new concepts is product development. And while there are skeptics out there who believe AI is the end of the world as we know it, this technology is growing so fast that in another 3 months it will become ubiquitous in the field of writing and creating everything.

ChatGPT and other AI apps are gaining popularity and there are now more than 15 of these apps out in the market place. Yes, students are using it to write term papers and do math problems, and this can be an issue down the road, but it also ushers in a new way to increase the speed of creating everything and with fewer employees. This concept has not been lost on major corporations who are already looking for individuals with some experience with these new computer models.

Pure Air Systems has been manufacturing commercial grade HEPA based, fan-powered air filtration systems since 1985 and will begin to utilize this new technology for enhancing its product line as well as writing some of its marketing materials.

Commercial HEPA Air Filtration Systems

Started in 1985, Pure Air Systems has been making commercial grade, fan-powered, true HEPA air filtration systems for over 38 years. The same high quality metal fabricated housings used then are still used today. High quality ECM motors and metal framed HEPA filters along with carbon media and ring panel prefilters are all part of the various systems offered by Pure Air Systems.

PAS makes units a number of systems ranging in air flow from 50 CFM up to 2000 CFM. These units are configured so they can be mounted either as stand-alone units or as part of an existing, ducted HVAC system. The powder coated painted 16 gauge steel housings can be mounted in side or outdoors depending upon the application.

The ECM motors provide for variable speed control using digital controllers or run by a computer system. In addition, they can be used in a a120 volt 60Hz electrical system or 240 volt 50 Hz system. This means they can be use in any location around the world.

HEPA filters are the best method of removing over 99.9995% of all particles 0.3 microns in size and larger and approach 99.99% for particles as small as 0.12 microns. They are used in all hospital and medical facilities and in commercial, military and residential markets.

Visible vs Invisible

Our eyes allow us to focus on and see airborne particles as small as 20 microns. For comparison, the human hair is about 100 microns in diameter. Most bacteria are in the range of less than 1 to 5 microns in size and viruses are less than 0.12 microns in size. So the old adage that what you don’t see won’t hurt you is not correct.

Bacteria, when present in a warm, moist environment, can stay alive for very long periods of time. From many hours to days. Because it is heavier than viruses it will not stay airborne for very long. So most contact with bacteria comes from contact with a surface or body part that caries the bacteria.

Viruses, on the other hand, are very tiny and light and can stay airborne for long period of time. This is how the flu and cold bugs are normally transmitted. Coming in a room or close contact where these viruses are airborne can infect another human once the viruses are inhaled and ingested. This is the reason masks are used in all medical facilities, especially surgical units.

Variable Speed Drive Motors Power Pure Air Systems HEPA Units

Pure Air Systems was founded in 1985 and at that time the electric motors used in their HEPA based air filtration systems were typical wound motors. These motors were only capable of running either at one speed, or 3 speeds if adjusted to the speed controller. They were also either 120 volt, 60 Hz or 240 volt, 50Hz. 

In 1998, PAS along with General Electric, started to play with the new ECM, variable speed drive motors that were magnet driven and not the typical induction motors used in the past. These new motors could run forwards, backwards and could controlled to run at 1% of power up to 100% of power in 1 percent increments. And, they were rated from 1/3rd HP up to 1 HP using the same base unit but by changing the drive add-on could be changed from 1/3rd HP or 1/2 HP to 3/4 or 1 HP simply by changing the controller section. 

In addition, by using digital controllers, the customers had the ability to change the speed of the motors and the level of filtration from any location in the room or proximate to the filter systems. These units could also be programmed to operate on a pressure differential basis so as to speed up the fan motor when the HEPA filters started to load up and create more static load. This allowed for continuous speeds throughout the life cycle of the HEPA filter.

The newer versions of these motors now allow for complete programing functions either from the factory or by the end user with some minor education by the factory. These newer motors, like the original variable speed drive motors, are now 120/240 50/60Hz so they can easily be adapted to working anywhere in the world. These new motors are used on the complete line of HEPA based air filtration systems offered by PAS. Models, 600HS, 1200HS, 2000HS, and the HPS Portable HEPA filter systems.

Comparing UV to HEPA Filters

While this subject has been addressed once before, it is important that people understand the stark differences between the two types of air purification/filtration systems. 

First, UV ( A,B or C ) is purely a type of wave length of light that has certain affects on a variety of materials, both organic and inorganic. The UV rays from the sun, for example, have a significant affect on carbon, plastics, and the human body. While the UV rays can destroy some airborne contaminants, the amount of time ( in minutes ) the contaminants are exposed to the UV rays determines the efficacy of the process. In essence, UV only works if the UV rays are in contact with the air stream for an extended period of time. 

HEPA filters are a mechanical device that captures airborne particulate ( down to under 0.3 microns and smaller) at an efficiency of 99.99% and greater. This is important as even organic particulates that are destroyed can create issues once inhaled into the lungs. 

One reason UV is often used in-lieu of HEPA filters is the overall cost of UV versus HEPA filters. Also, the use of HEPA filters requires an auxiliary fan source as HEPA filters have a very high resistance to air flow and in order to pull enough air through the filter media requires a motor/blower assembly in addition to the blower assembly that comes with all HVAC systems.

Pure Air Systems offers a complete line of fan powered air filtration systems to meet the needs and demands of any residential or commercial application requiring the reduction and/or removal of airborne contaminants and also odors and gaseous pollutants.

Carbon For Odor Control

For many years carbon media or expanded carbon, has been used for the reduction and removal of organic and inorganic gaseous pollutants. Expanded carbon or charcoal is produced using heat under high pressure that creates a surface area that has thousands of tiny openings that are capable of adsorbing gaseous molecules much higher in weight than the carbon itself. 

While carbon granules are often used in liquid filtration, the most common use is in air filtration whether in a stand alone filter or fan powered air filtration system. Carbon media filters have a fair amount of resistance and are therefore more often used in conjunction with a fan powered unit. 

Even though the expanded carbon has a high adsorption rate to weight of the carbon media, it will, over time, load up and stop adsorbing the odors or gases. Replacement cycles can be as long as once every 6 months to once every 6 weeks depending upon the severity of the gaseous pollutant.

Summer Months and Home Indoor Air Quality

For the majority of the U.S., Summer represents hot days, hot nights and in many parts of the U.S., high humidity. This means that for the most part people will remain indoors in their homes, offices and shopping areas in the presence of cool, air conditioning. 

While air conditioning keeps the interior space cool and removes the majority of the humidity, the lack of any outside fresh air means that all the air in the home, office, school or shopping areas is stagnant or stale. Without any type of effective air filtration, the levels of airborne particles (which can include, human skin, bug matter, airborne dust and debris of all types) will increase 10 fold. And, if there are animals present, then the potential for high concentrations of animal dander may occur.

In order to minimize the health hazards of breathing stale, polluted indoor air for long periods of time, we recommend using good air filters on your returns or consider putting one of our 600HS Plus HEPA systems on your ducted forced air HFAC system. With the unique partial-bypass installation concept it is possible to filter all the air in your house up to 24 times per day and introduce a small amount of outside, filtered fresh air without upsetting the AC temperature and humidity in your home.

HEPA Systems For New Intel Chip Manufacturing Facilities

Intel is investing $20 Billion dollars to build two state-of-the-art Micro Chip manufacturing plants in Albany, Ohio. Chip manufacturing is done in Class 10 and Class 100 clean room facilities which are constantly being cleaned by HEPA filters with the rooms being under positive air pressure.

Chips are comprised of multiple layers and then assembled together. These layers are highly sensitive to any airborne particulate, even in the sub-micron level, as the dust particle will destroy the chips function and short it out when in use. The types of HEPA filters used in the manufacturing and assembly areas are normally comprised of a series of HEPA’s in banks. They use HEPA, ULPA and SULPA HEPA filters that will remove 99.9999% of all particles 0.12 microns and smaller. As as comparison, the Human hair is about 100 microns in diameter.

Pure Air Systems has been providing commercial grade, fan powered, scanned HEPA filters ( 99.99% at 0.3 microns) since 1985. Many of these systems have been and are being used in smaller micro chip operations, medical facilities, hospitals, military and institutional plants. The PAS systems range from 50 CFM up to 2000 CFM and can include Carbon media along with a Prefilter.

Removing Airborne Gaseous Pollutants

The removal of gaseous pollutants ( odors ) is often accomplished by using a masking agent sprayed into the room or area with the odor. If the odor is temporary or infrequent then the aerosol spray deodorizers will usually meet the task. If, however, the odor is from a continuous source and is strong enough or dangerous to breathe then commercial grade carbon media filters will be required.

The use of expanded carbon ( charcoal) for the reduction/removal of airborne gaseous pollutants has been around for over 100 years. These carbon media packs ( usually 1 inch to 4 inches in depth) can be very effective at removing these strong, continuous odors and the carbon can be combined with other materials to catalyze some pollutants that are not removed by just carbon alone.

Pure Air Systems, has been manufacturing HEPA and Carbon based, fan powered, commercial grade air filtration systems, since 1985. These metal framed units incorporate the newer variable speed motors and the air flows range from a low of 50 CFM up to 2,000 CFM. PAS offers a wide range of sizes and configurations to fit any specific need. Some of the large units can hold up to 80 lbs of carbon media or applications where high concentrations of gaseous pollutants are present.
