Gaseous Pollutants Reduction and/or Removal

Airborne pollutants come in many forms. Some we can see like smoke from manufacturing or burning leaves, or particulate in the air from a wide range of sources. But there are many pollutants that are invisible to the naked eye but may produce strong odors some of which can be deadly in large concentrations. Odors produced outside tend to dissipate quickly and unless you are next the source you may not even notice it. On the other hand, gaseous pollutants in closed spaces can be extremely dangerous unless either properly vented or contained in a controlled environment.

Many household odors such as odors from pets, food, cooking, smoking or from various crafts, can be somewhat harmful or a strong irritant if inhaled over a long period of time. These gaseous odors are not removed with standard furnace filters, as those are primarily for capturing airborne particulate, rather you will require a material that will adsorb the gaseous particles. Typically this material is comprised of activated carbon ( charcoal ) and placed in the return air stream of the HVAC system or used in a stand-alone, fan-powered unit.

Carbon is one of the most effective media for reducing and/or removing gaseous pollutants from the air. Expanded carbon has a very high surface area and can adsorb over 100 times its own weight in gaseous pollutants. This material is often contained in a mesh type bag or cannister with perforations to allow air to pass through with minimal resistance. Carbon does have some limitations in that once the carbon has adsorbed it available capacity it will then begin to release this same odor back into the air stream. Typically this material will last 2 to 4 months for most applications before it has to be replaced.

Pet Dander Is Not Removed By Furnace Filters

One of the strongest allergens is pet dander, especially cat dander and their reactions can be from mild irritation to full-blown respiratory distress. Dander is basically skin flakes that are shed by any animal, including humans. 

These skin flakes can be airborne for short periods of time but usually too heavy to be carried by the air currents in any home or building environment for any period of time. If a cat or dog is running through the house and runs by someone who is allergic to dander, there may be enough dander in the air to cause a reaction. If that person comes in contact with the animal then the dander can attach itself to their clothing or is discarded on the furniture from where they may lay. Once the person inhales the skin flakes their specific allergic reaction will begin and may last for a number of hours or all day. 

Because the dander is not always airborne, the air filters in your return air intake will not see much of that airborne particulate. It is often better to use a portable air filter such as a HEPA filter that uses a fan to pull the air through the room. These can be placed in a bedroom or family room, preferably where the animals do not often track. This will keep that area cleaner and a more significantly reduced level of animal dander.

Pure Air Systems offers a small, powerful, adjustable speed HEPA filter unit that is only 21 inches long and 13 inches square. It can move up to 500 CFM and has a variable speed motor for infinite air flow adjustment. It is easy to carry and can be placed on a table or even the floor if necessary. Putting a filtration device in a area that is considered a safe zone for humans offers the best option for keeping animal dander to a minimum.

Pure Air Systems – Real Content – Not Social Media

I must say that I am getting tired of all these Twitter, YouTube, Instagram, etc. sites that tell me things like: “If you look outside and see that liquid falling from the sky….that is rain. And let me tell you why it falls the way it does.”  Really,? Have we arrived at point in our lives that we can only verify what we saw because someone else used social media and told us it was real? 

These are some of the reasons why companies and individuals who actually have valuable and reliable content on their websites and blogs dislike social media. They now have to shift to the “Bizzaro World” approach to get anyone to pay attention. If you are looking for real content then take a look at the Pure Air Systems website. A company that is now 36 years old and one of only three companies left in the world that make this type of fan powered, commercial grade, HEPA filtration system.

In early days of PAS, a lot of content was written for the site that provided easy to understand technical information about all types of air filtration systems, including those sold by competitors. This part of the site was titled:  Pure Air University. It is still a viable section of the website and often used by those searching for real, technical, information written in a format that is easily understood by the laymen. This data forms the basis by which all types and styles of filters are rated and is still one of the most widely read of all the data on the site.

Pure Air Systems Shares Rarified Air

Created in 1985 by Don Musilli, Pure Air Systems was one of many companies offering air filtration systems for the commercial and residential markets. But the separation from the competition began shortly thereafter. From the beginning, PAS used an all metal housings, Lau Blowers, GE Motors and commercial grade prefiters, carbon media and HEPA filters. The initial units sold for $695.00. Over time, PAS added other units to their line up and in 1998 became one of the first powered fan filter companies to use the new GE ECM variable speed drive motors. 

The addition of the new motors and expansion to a 9,000 sq. ft. building allowed PAS to expand their product line to 7 different size air filtration systems all of them now using the upgraded, digitally controlled variable speed drive motors. The ability for the motors to be 120/240 50/60 Hz created a new market overseas for the larger systems. The new HPS portable unit opened the doors to more medical markets and the Covid – 19 global pandemic created a whole new market for commercial grade HEPA air filtration systems.

Today, there are only two other companies in the world that make a fan powered, commercial grade HEPA air filtration unit handling up to 2,000 CFM and as low as 50 CFM. With material costs for metal and other components increasing rapidly, it is much more difficult for companies to offer products such as the ones from Pure Air Systems.

Pure Air Systems Is Major Supplier Of Filtration Systems To Fight Covid-19

Created in 1985, Pure Air Systems was one of the first US companies to offer commercial grade, fan powered, HEPA air filtration systems for the general publc. These systems are designed to be used as both stand-alone units as well as attaching them to existing HVAC systems to provide central and whole house filtration. Over the next 10 years Pure Air Systems developed seven different sizes and configurations varying in air volume capacity from 50 CFM to 2,000 CFM. In addition the systems had the capacity to add carbon media and prefiltration in conjunction with the HEPA filters providing systems that could handle almost any air filtration or odor challenge in the market.

When Covid-19 entered the globe in eary 2020, many of the hospitals, clinics, laboratories and municipal facilities across Norht America started lookng for HEPA based air filtration systems as HEPA filters are the only type of air filter that can remove a subtantial amounty of airborne viruses. Standard air filters are, for the most part, not very effective in removing these sub-micron particulate from the air. 

The Pure Air Systems units use very powerful, variable speed drive motors ranging from 1/3 HP to 1 HP, they can move a lot of air through the HEPA filters which are extremely dense. In additon, the units can move air through ductwork that is connected to the filtration systems so they can be used to provide clean air in a large space. The systems can also be used to create either a positive or negative room area for patient isolation as is the common practice in most Hospitals.

Today, Pure Air Systems is one of only three companies around the world that produces a metal framed, commercial grade, fan powered true HEPA air filtration that can be used in a very wide range of applications in the residential, commercial, institutional, industrial and medical markets.

Portable HEPA Filter Systems For Any Application

There are many commercial and institutional applications where a true HEPA filtration system is required but space and time of need is limited. Pure Air Systems, based in Indianapolis, manufactures a complete line of HEPA and Carbon based, fan powered air filtration systems that range in air flow capacity from 50 CFM to 2,000 CFM. These systems use high end blowers and motors and are framed in all metal housings.

The HPS model portable units from Pure Air Systems have a four speed motor/blower, a ring panel prefilter/carbon media filter and a true, scanned HEPA rated at 99.99% at 0.3 microns and larger. These portable units are 13″ square by 24″ long and weigh only 34 lbs. These units are very powerful and can move up to 250 CFM of HEPA filtered air. While these units are often used in small laboratories, hospital rooms, nursing homes, clinics and mobile trailers, they are a perfect filtration system for the home and office. 

The powerful fans allow you to use this system either as a stand-alone system or attached to duct work so they can move air through a fairly large area and can also be used to provide positive or negative air pressure in any enclosed space. The PAS HPS series are the most powerful portable HEPA units on the market today and the average length of time in service of 15 years.

Pure Air Systems also offers a complete line of HEPA based systems that are designed with unique configurations so that you can install a unit in any location with the ability to have the inlet and discharge in any direction for best installation and performance.

Pressurizing Your Home With PAS HEPA Filtration Systems

The majority of most homeowners are not aware that if their HVAC system is not properly balanced, when the heating/cooling fan system comes on the house may be pulling in outside air into their environment. This is referred to as the house being negative. Since your home is not really air tight, anytime the HVAC fan comes on the system will pull air through the returns and push the cooled or heated air our the supply ducts and registers and if there is more return than supply outside air will come in and make up that difference. 

This is a significant challenge as the air being pulled in from the outside will contain fine airborne particulate and some gaseous pollutants especially if you are near a road or high traffic area. This airborne dust is usually not captured in any of the air filters that are part of your HVAC system so this particulate matter will usually settle out on your floors, furniture and counter tops.

In 1985 Pure Air Systems was created and it was one of the first companies to offer true fan powered, certified HEPA air filtration systems for the residential market. The first model, 600HS was designed to attach to the return air side of the ducted heating/cooling system and filter a portion of the air in the house constantly when the fan was running. In most cases it can filter all the air in the house 24 to 48 times per day. 

One of the other advantages of this system was the inclusion of both a ring panel prefilter and true carbon media filter so removal of fine sub-micron particulate and gaseous pollutants was also accomplished. In addition, it is possible to introduce a small amount of outside air into the 600HS, or whichever PAS unit you are using, and this will fill filter any of the air coming into the house and help to maintain a more balance house pressure while still cleaning all the air in the house. And because this small amount of outside air is being introduced prior to the HVAC unit. all of it will be both filtered and heated or cooled.

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.

Airborne Bacteria Removal and Reduction

For those individuals who live along the South West coast of Florida, this year has been especially challenging with the long last issues caused by Red Tide. This algae bloom is a common occurrence during the summer months and often begins out in the Gulf of Mexico. This year the Algae bloom has been larger and extends from Naples up to Tampa Bay. In addition, the blooms are toxic and kill sea life and produce an airborne bacteria that is harmful and potentially fatal to humans.

In 1985, Pure Air Systems was founded to bring true HEPA based air filtration systems to the residential market. These fan powered, metal housed units, are capable of providing surgery suite environments in all types of buildings and for all types of airborne contaminant applications. These true, commercial grade, scanned HEPA filters can remove up to 99.99% of all particles 0.3 microns and larger.

In the case of the Florida Red Tide issue, there are many days when the number of dead fish on the shore which produce a significant odor and also a release of toxic bacteria into the air which is blown onto shore and into the populated areas when the prevailing winds are out of the West. By applying the HEPA based technology used in the Pure Air Systems air filtration units, businesses and home owners along this stretch of shore line could effectively and safely remove a very high percentage of this airborne particulate and protect the health of those that live and work in this area.

The HEPA based air filtration systems offered by Pure Air Systems consist of small portables with volumes up to 350 CFM to large commercial units with volumes up to 2,000 CFM. PAS also utilizes variable speed drive motors so they can control the air volumes for 1 to 100% in 1% increments to provide the correct amount of air flow for the application. PAS units are used in the residential, commercial, institutional, medical and industrial markets.

Pure Air Systems New Website

Back in 1992 the internet was just starting to become more relevant and the only site that you could surf ( a term we used back then ) was Internet Explorer by Microsoft.

Pure Air Systems understood the value of using the internet as a mechanism for promoting our company and its’ products. Pure Air Systems was founded in 1985 so for the first 7 years we used traditional mailings and the phone for all of our marketing.

In 1992 we found a small company that could build a website and we set up https://www.pureairsystems.com.  The name has not changed in 26 years but the website has gone through a number of changes since its birth on the internet.

The first website looked more like what we call a landing page today. It was one page with photos that were not very good and some basic information on the products and our phone number and email address.

Two years later we created a more in-depth website that gave more information and better descriptions of our line of HEPA and Carbon based air filtration systems. That site had the Pure Air University section which was designed to provide objective information on all types of air filtration devices. This allowed potential customers to gain some knowledge about all the competitive types of air filters so they could make a more objective decision on selecting a system that would work best for their specific problem.

The new site has a great new look and is much  easier to navigate. Pure Air Systems only makes commercial grade air filtration systems which are used for both commercial and residential applications. This was not well understood with the previous website.

Pure Air Systems has been around since 1985 and is one of the most successful air filtration companies in North America for supplying commercial grade, high performance, fan powered HEPA based air filtration systems for the residential, commercial, institutional, medical and industrial markets.
