Why China Is Buying Our Filtration Systems

I remember back in 2004 when my Father and I traveled to China. My Father liked to travel and asked me to tag along and I did. We landed at the then, new airport and took a bus to Beijing. Coming into downtown Beijing at night was like driving into Manhattan except all the signs were in Chinese. Otherwise it was strikingly similar with the exception of one thing, the smell of unburned hydrocarbons created by the massive use of coal for heating, cooking and manufacturing.  Along with the smell you could see a light haze in the air that was more transparent that opaque. The Chinese had a very bad pollution problem.

Fast forward to today and this issue of significant air pollution in China is now affecting other parts of the world as well. The massive clouds of dust, dirt and soot climb into the upper atmosphere and are carried thousands of miles by the prevailing winds. This soot then falls to earth in countries far removed from mainland China. In addition, the pollution creates significant health issues for the Chinese to the point where many people wear masks when they are outside.

A year ago, in March of 2013, an import/export company contacted Pure Air Systems, located in Indianapolis, IN, to discuss the possibility of exporting their portable HPS series units to China for by some of the wealthier individuals to remove the smoke and odor from their homes. The increase in the Chinese economy has created a large number of wealthy people who are willing to pay higher prices for products from the U.S. It seems that the Chinese don’t like things that are made in China either. While there is some significant technology development on-going in parts of China, most general duty products are poorly made with minimal repair options available.

A number of the portable units have been shipped to China for testing. One of the things that the Chinese people want to see on the units is the “Made in the USA” labels on the equipment and know that they are real. They also want to see the specifications on the components and know that 90% of them are fabricated anywhere but in China. One of the major hurdles with this venture is getting the units past customs and approved as an import item. The Chinese are very protective of their businesses and only allow certain items to be imported. Somewhat ironic.

Sometime in the next few months Pure Air Systems will have some definitive feedback from the exporter as to whether or not PAS will be successful in getting some product sold in China. Stay tuned for the results.

Pressurization As A Means Of Air Filtration

The reduction/removal of airborne particulate is usually accomplished by the use of air filters or filtration systems. The filters may be installed in a ducted heating/cooling systems return air grill or as a stand alone unit that circulates the air in a specific room or building. These types of filter systems are the most effective as they allow for circulation of the air within the room and while keeping the room temperature and humidity levels constant.

On the other side of the equation is the use of pressurization to reduce particle levels and/or maintain a higher degree of fresh air in a room, building or environment. To pressurize any room or space you simply need to draw in or pull in enough air from an outside source to change the pressure gradient in the room from either negative or static to a positive pressure room. We can all identify with positive or negative pressure as seen when we enter a large building or office and when opening the door the air blows out into your face ( positive pressure) or you have some difficulty opening the door ( as it seems to be pulled away from you) and overcoming negative pressure.  Another way to identify positive or negative pressure in a room is to open the main door about 1″ and take some smoke or a piece of tissue paper and place it at the door opening. If the smoke or paper moves toward the opening the room is negative, if it moves out toward you the room is positive.

The use of positive pressure as a means of filtration or “room cleaning,” has some major drawbacks. First, the air you bring into the room would probably be from an outside source. Although in a large building you could pull air from any space in the building and pressurize the room but that air may be just as dirty as the air in the room you are attempting to clean. Therefore, using an outside air source for pressurization is usually better but is comes with some costs.

Unless you live in a part of the country or world where the daily average temperature is around 70 degrees fahrenheit  and the humidity is 40% or less, bringing in outside air to pressurize a room will substantially alter the temperature and humidity in the pressurized environment.  In order to use pressurization effectively you would need to introduce at least 30% outside air as it relates to the amount of air being heated or cooled in the room.  For example is you have a room that circulates and conditions 600 CFM through its heating/cooling system you would need to introduce at least 180 CFM of outside air to remove some of the  airborne particulates or contaminants.

This process is often used in smoking areas in bars and lounges and in locations where odors, gases or fumes are being generated and dilution by introduction of outside air is the least expensive alternate. The amount of air introduced from the outside would vary depending upon the type of contaminant as just mentioned. It may be that up to 50% dilution is required to effectively reduce the levels of contaminants, however, this large amount of air will displace half the air in the room so some form of vent is needed to allow the fresher air to come into the room and push the contaminated air out of the room. It will also significantly impact the heating/cooling/humidity levels in the room or space.

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.
