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.

Using Air Filtration System As An Air Curtain

Air curtains are designed to be placed above a large door or opening to create an “air barrier” so to speak, that will keep the air from one side of the curtain from entering the other side of the curtain. This is accomplihed using a high volume industrial blower and fan with a fairly powerful motor. Usually 1/2 HP to 1HP. The air is produced by the fan and forced through manifold that is placed along the top edge of the door and extends the entire width of the door. The opening of the flow side of the manifold is very small in comparison to the air entry side of the blower. This design create a venturi affect that jets air downward at a very high velocity. 

Pure Air Systems has a series of fan-powered HEPA based air filtration systems that can be used as the main source of fan power for an air curtain while also maintaining a contaminant free air door. These HEPA air curtains are often used in food processing, medical product manufacturing, laboratories and medical facilities. The main advantage is the speed of entering or exiting a room without having to open or close a door. This is a real advangtage when the door opening is very wide and would require either double doors or a horizontal sliding door. In addition, you could have more than one person moving throught the opening at one time. 

Pure Air Systems has been manufacturing HEPA and Carbon based air filtration systems that are fan-powered and with all metal housings since 1985. These units range in air flow volume from a low of 50 CFM to 2,000 CFM. The PAS units come standard with a true, scanned HEPA filter, Carbon Filter and Prefilter. All components are made in the USA.

High Performance HEPA Portable By Pure Air Systems

Pure Air Systems has been making commercial grade, fan powered HEPA air filtration systems since 1985. They are one of three companies in the world that provide this type of filtration systems. PAS makes a number of models of HEPA systems that range from 600 CFM to 2000 CFM all using variable speed drive motors. Their portable system, the HPS series was introduced around 1992 and has since gone through a number of refinements. It was the only HEPA unit in the line-up that did not use a variable speed drive motor. In stead, it used a 4 speed motor from EBM. 

Coming this year, PAS will be fitting the popular portable HPS unit wiith it’s own variable speed drive motor. This will allow for a CFM range from 25 CFM up to 250 CFM in 1% increments. In addition, the new motor will be designed to maintain the same speed/cfm rating even as the pressure drop increses across the HEPA filter.And likes the original version, the new HPS unit will have a prefilter,carbon filter and a true 99.99% scanned HEPA fitler as standard equipment.

The portable HEPA unit has a wide range of applications and is very well suited fror the laboratory environment as well as small confined areas requiring HEPA filtraiton in both a positive or negative room application. The all metal housing and rugged construction make this one of the best portable HEPA systems on the global market.

HEPA Filters. High Efficiency Particulate Absolute

HEPA filters were developed in the early 1940’s during the creationg of the atomic bomb.The use of radioactive materials in the making of the bomb created extreme health hazards for the technicians and engineers that had to handle this type of material. Due the extremely small size of the radioactive particles ( Sub-micron in size ), readily available air filter media like furnace filters, were totally useless in reducing the levels of radioactive particulate. They needed a filter material that could absolutely remove and capture these tiny particles. 

After trying a number of materials a process using a wet laid paper type material infused with tiny pieces of glass was used to develop a very dense material that was capable of filtering out these tiny sub-micron particles. The paper like material was formed into an accordian style form with pieces of aluminum sandwiched beteween each folded layer to protect the paper-like media as it was relatively fragile and could abrade by rubbing on itself.

The filter pack was placed inside a square medtal housing and was glued in place. The outside parameter of the metal housing had a neoprene type gasket so when it was placed in a sheet metal duct it would compress the gasket to form a leak-tight seal. These filters had an initial efficiency of capturing 99.97% of all particles 0.3 microns and larger and as it got dirtier its efficiency increased. The use of this HEPA filter allowed the technicians to work in a safer environment culminating in the eventual creation of the two bombs used on Japan to end WWII.

HEPA Filtration For Asthmatics

Asthmatics suffer from airborne allergens more often than people with just normal allergies to pollen, ragweed, animal dander, etc. For many asthmatics a small level of dust or airborne particulate can trigger an asthma attack and the only relief comes in the form of an inhaler or other quick acting medication. 

Allergy sufferers can take a number of over the counter medications to help relieve symptoms especially the runny nose, irritated eyes and general stuffed head feeling that are very typical. Being in an environment where they amount of allergens can be reduced will significantly help reduce or eliminate the typical reactions associated with allergy sufferers. 

Pure Air Systems has been making HEPA based, fan powered air filtration systems since 1985. For over 39 years people around the U.S and overseas have been able to use these high performance air filtration systems from general duty air particulate removal to surgical suite operations and everything in between.  The ability to use these systems with standard forced air ducted heating/cooling systems has enabled thousands of allergy sufferers to have almost complete relief when they are in their homes or offices. The HEPA filters are commercial grade and certified at 99.99% at 0.3 microns and larger. The three stage filtration system also includes a dual layer ring panel filter and carbon media filter for odors and gases.

For asthmatics, the PAS line of HEPA systems has proved to be one of the few HEPA based air filtration systems that can both  reduce the levels of airborne particulate while also pressurizing an entire house, office area or large room. This highly effective system has shown to significantly reduce the need for or use of inhalers for the area being actively filtered. Pure Air Systems also makes portable units that can handle an individual room or small area. These are perfect for a child’s or adult’s bedroom or small house or condo.

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.

Installing Pure Air Systems Filtration Systems On Horizontal HVAC Units

Pure Air Systems has been manufacturing fan powered, HEPA based, commercial grade air filtration systems since 1985. With seven models to choose from PAS offers a system for any application in the residential, commercial, institutional, medical or industrial markets. Their systems can be attached to any type of ducted HVAC system or used in a stand-alone configuration.

Traditionally, the 600HS Plus L version was used on only up-flow HVAC systems located in a garage or basement. In some parts of the country, specifically areas of the South where there are no basements ( i.e. Florida ) a horizontal air handler is utilized. This makes is somewhat challenging to install the 600 HS L version as it can not connect to the return air side of the air handler due to the configuration. The PAS “S” version is a straight thru unit that could be mounted above the or to the side of the horizontal air handler or even in the attic area where space is available. 

Like the L version of the 600HS, the “S” version is split into two symmetrical sections so you can rotate the discharge and inlet access doors to one of four positions thus allowing for installation anywhere so you always have access to the blower/motor and filter sections. The 600HS model produces 600 CFM of HEPA filtered air using a 1/3 HP variable speed drive motor. There is also a 1200HS Plus version, producing 1200 CFM of air and a 2000HS Plus version, producing 2,000 CFM of air. All of these units come in either the L or S versions. And, they can be wired to either connect to the HVAC system or use a digital speed controller to run the units manually from 1% to 100% in 1% increments for specific air flow requirements.
