Removing odors and gaseous pollutants from any environment is much difficult than removing airborne particulate. There are a number of air filter types that can easily remove airborne dust, but the removal of airborne odors and gases requires some very specific materials that can effectively adsorb these organic or inorganic molecules.

The most common material used to remove odors is activated carbon ( charcoal) which comes in a number of sizes. The most common is cocoanut shell carbon that is usually around 1/4″ in size and is often enclosed in a mesh type material or sometimes in a fine opening screen container. Carbon can be used in both air and water for the extraction of gaseous pollutants, making it one of the more popular materials on the market.

When cocoanut shells are placed in a high temperature oven under pressure it expands the surface area of the material and then makes it into a carbon material. The expansion to the shell gives the material a very high surface area and the ability to adsorb up to 100 times its own weight in gaseous pollutants. This means that a small amount of carbon material can remove a large amount of the odors and last a long period of time. 

Pure Air Systems has been manufacturing HEPA and Carbon based, fan powered, commercial grade air filter systems since 1985. The various systems available from PAS include carbon media as a standard part of the filtration unit along with a prefilter an HEPA filter. In cases where a customer only has an odor or gaseous pollutant issue, Pure Air Systems can remove the HEPA filter and replace it with an all carbon bed of material. Depending upon the odor challenge, the systems can hold from as little as 8 lbs of carbon up to 60 lbs of carbon material. And the air flow capacity of the systems range from 50 CFM to 2000 CFM.

Pure Air Systems began its journey in 1985 producing one of the first true, commercial grade, fan powered air filtration system that could be used in either commercial or residential applications. These units were made from 20 gauge mild steel that is powder coated for a durable, long-lasting finish. 

Today, the line up of 7 different systems made in variations in both size and air flow design are still made from the same high-grade 20 gauge powder coated steel housings now using the latest iteration of the variable speed drive motors that are digitally controlled. The HEPA filters are all 99.99% efficient at .3 microns and larger and the prefilters and carbon filters come standard with each unit. 

The HEPA Shield systems come in air flow ranges from a low of 50 CFM from our portable unit up to 2,000 CFM on our largest model 2000HS unit. These systems can also be modified to be attached to an existing HVAC duct work system or as stand-alone units. 

Pure Air Systems are all made here in the USA with most of the components manufactured in the US. Some of the original units are still in operation and the average longevity of any of the systems is better than 15 years. Making the PAS units one of the best economical purchases for any air filtration system on the market today.

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.

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.

Carbon that is used for odor control if often made from expanded cocoanut shell carbon. This type of carbon has a high surface area and very high ratio of molecular adsorption to weight of carbon. This makes this material suitable for both adsorption of organic and inorganic odors and gaseous pollutants in both air and water applications.

For general odors found in most homes; typically pet, cooking and carpet odors, carbon filters placed in the HVAC system will be capable of removing about 50% of those odors with a replacement cycle of once every two months.

For commercial and industrial applications, it may be necessary to use large carbon beds, 10 – 20lb pads of carbon, to significantly reduce the the gaseous pollutants. And, in some cases, a catalytic material like zeolite may be required to enhance the adsorption of the gaseous pollutants. Depending upon the amount of pollutant being released it may be necessary to replace these carbon pads as often as once a week. 

Odors such those produced by cigarettes are some of the most difficult to remove as the nicotine smoke produces a sticky residue with adheres to almost any surface and releases that odor for long periods of time. Carbon can help in these cases but replacement of the carbon can be up to once a day.

Almost 80% of the products purchased on-line from Amazon, Walmart, Ebay and other web based stores, are manufactured in other countries. The majority being made in China. However, many of these products, including Apple iphones, etc, say they are designed in the US but made overseas.

Pure Air Systems has been designing and manufacturing their fan powered, commercial grade, HEPA air filtration systems since 1985. While some of the motors are now made overseas, over 90% of the components that make up the filtration system are made in the USA. These units have shown to be some of the best on the market and many of these systems are still in operation after over 20 years of service.

It is more expensive to purchase components and parts made in the USA and often times a wider selection of component and part types are available from outside the US. Manufacturing is a very challenging process and requires a lot of up front capital to obtain the machinery and skilled labor to make almost anything.

Pure Air Systems continues to look to the US companies to make any new components or parts that are needed for the existing and newly designed units. While these may be more expensive it is important to continue to use parts made in the US to keep these manufacturing operations viable.

3D Printing or Additive Manufacturing as it is called in the commercial market, has moved into almost every facet of manufacturing from small replacement parts and dental fittings up to Aerospace and Military applications. There are very large 3D printers making boats as well as printing houses and large structures and small bridges.

3D printing has a number of advantages including the ability to try the “what if” and prototyping of new design concepts. In addition, the materials available for the metal printers has moved this process in the main stream of manufacturing. 3D Printers take up much less space than traditional CNC machines and other fabrication systems and require fewer people to complete the manufacturing process.

One of the main advantages of using 3D manufacturing is the ability to get younger people to become more involved with manufacturing. The younger generation is very familiar with and is good at using CAD type software for design and 3D printing of parts. In truth, the ability to make things using 3D printing or Additive Manufacturing is not considered manufacturing to the younger generation. This is important as they are not interested in moving into the old type of making things. 

Pure Air Systems, an air filtration company started in 1985, has bee using some 3D printing processes for prototyping new parts for their metal housed HEPA based air filtration systems. This helps them more quickly determine the correct part design and more quickly complete the final design and get into production with minimal cost.

Discussions about AI have been around for the past 20 years. However, the ability to use the new AI apps and software to enhance, modify, alter, create and change everything. The new platforms can revolutionize the time it takes to write books, create paintings, develop formulas, and enhance all forms of social media. 

In the area of manufacturing, AI can assist in creating the most efficient way to make an object or select better materials and manufacturing methods to accomplish a task in half the time with less material usage. Companies that utilize this technology will be far ahead of the competition. For all the naysayers and podcasters that are out there down playing AI’s role in the future, the truth is that this technology will very quickly become mainstream before the end of 2023.

Pure Air Systems, a 37 year old company, manufactures a high end line of commercial grade, fan powered, HEPA based air filtration systems and is strongly considering utilizing AI to make changes to its design to cut material and production costs. As the price of all components continue to rise it is becoming more important to utilize all the tools available to maintain the bottom line and scale up the business. AI is one of these tools.

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.
