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.

HEPA Filtration Systems As Air Booster

Using HEPA filtration systems as air moving boosters is fairly common and in most cases necessary. If you have a multiple number of pick up points from which you want to remove contaminated air you need to understand the concept of air flow resistance or pressure drop.

When moving air through any type of duct system you have to take into consideration the resistance of air flow through the duct especially if it is flexible duct and you have some 45 degree and 90 degree bends. Air flow resistance is measured in inches and the higher the number the greater the resistance the larger the horsepower has to be on the motor/blower system that is moving that air from one point to another.

If you have any type of air filtration device in the air flow system that being used to remove the contaminants you also have to take into account the static pressure loss across that filter as well. If it is a HEPA filter you have a significant pressure drop which needs to be added into the total line loss when designing the blower/motor system.

Pure Air Systems has been making fan powered HEPA based air filtration systems since 1985. They use variable speed drive ECM motors on all their systems that adjust automatically by speeding up as the pressure drop across the HEPA filter increases.

Since Pure Air Systems makes HEPA filtration systems that are fan powered they can be used as boosters for moving air through an entire ducted system to maintain the proper carrying velocities through the ductwork even as the HEPA filters load up.

It takes a lot of power to move air through ductwork and a filter so using the PAS systems makes sense. The models range from 600 CFM to 2000 CFM air flow capability using 1/3, 3/4 or 1 HP ECM motors. PAS is one of the few companies in the world that make high end, fan powered, commercial grade HEPA air filtration systems that can be used as stand-alone systems or in conjunction with a ducted HVAC system or commercial air handlers.

Particulate Removal With HEPA Filters

The process of removing airborne contaminants that are small enough to potentially cause respiratory dysfunctions is somewhat challenging. For the most part particulate removal with standard air furnace type filters is effective on larger, visible particles many of which are aspirated in and then expelled out of the lung systems.

Sub-micron sized particles, those that are less than 1 micron in size, are easily aspirated into the lungs and much of this particulate will stay logged in the lung linings or mucus membranes. This is why particulate removal with HEPA filters is so necessary especially in where airborne allergens and harmful bacteria and viruses are present.

Originally designed during the development of the Atomic Bomb in Los Alamos, New Mexico, HEPA filters have progressed to include filter medias that are more effective than the 99.97% at 0.3 microns. Today there are SULPA filters that have an efficiency of 99.99995% at 0.12 microns. These are the types of filters used in Class 10 clean rooms where micro-chips are manufactured.

Pure Air Systems began using HEPA filters for particulate removal in 1985 in their first system, the Model 600H. This fan powered HEPA based air filtration system could move up to 600 CFM of HEPA filtered air. Today, PAS makes 6 other HEPA based models including a portable HEPA unit capable of moving from 10 CFM to 250 CFM using the newer ECM motors. The largest system, Model 2000HS Plus moves up to 2,000 CFM of HEPA filtered air.

Over 70 years ago the HEPA filter was born to protect the technicians from beta particles produced during the design of the bomb. Today, particulate removal with HEPA filters is considered the best method for protecting us from harmful airborne contaminants.

Life Insurance

Life Insurance has many advantages especially if your dependents are on the receiving end of the payout. For you, not so much since your demise benefits other people.

Insurance is designed to cover risk. If you don’t believe that life has risks then don’t get insurance. However, your state requires you have insurance to drive and not having insurance on your home takes real guts…and a large bank account.

This leads us into the discussion of how best to insure ones self with minimal costs and maximum benefits. I am talking about insuring your health. Obviously seeing a Doctor on a regular basis and eating healthy and exercise do matter, but breathing good, clean, pollution free air is also very important.

Pure Air Systems started its business in 1985 selling one of the first true, commercial grade HEPA air filtration systems in the U.S. Beginning with one model over time, PAS developed 6 additional systems over the next decade and today, 32 years after it started, is now one of the major players in the world of HEPA air filtration systems.

These units are designed to be used in residential, commercial, industrial, institutional and medical applications. PAS was the first and is still the only company to apply a large, fan powered HEPA system to any forced air ducted HVAC system in the residential market. Customers who have installed these systems have seen dramatic results in reduction and / or removal of airborne contaminants that can cause severe respiratory dysfunctions.

In addition, the use of the PAS HEPA systems has propelled the companies products into markets all over the world. The use of the variable speed ECM motors in all the units allows them to be used in any country as they can operate on 120/240 50/60Hz electrical systems.

HEPA Type Filters Are Not True HEPA Filters

For the uninitiated, HEPA is an acronym for High Efficiency Particulate Air or Absolute. For many years these types of filters were called “absolute” filters because they basically captured absolutely all airborne particles that came in contact with the filter media.

HEPA filters are made from a special wet-laid material that has glass fibers as the basic material. It is then smoothed out like the making of paper and that is why the material is referred to as HEPA paper. It is also very fragile and can be cut or torn very easily.

HEPA filters have to meet a very stringent set of requirements before they can be labeled a true HEPA filter. They must be able to remove a minimum of 99.97% of all particles 0.3 microns or larger with a high efficiency below the 0.3 threshold. The media pack has to be sealed in a metal or aluminum frame and have a gasket on the downstream side to ensure complete sealing between the filter and the box or device in which it is placed.

HEPA filters are expensive. Very expensive and some of the new, higher efficiency filters like the ULPA or SULPA HEPA filters which are used in clean room applications and micro-chip manufacturing are 2 to 3 times more expensive than standard HEPA filters.

HEPA Type Filters are called that by competitors that don’t make true HEPA filters. These are filters that have a high MERV ratings. HEPA filters have a MERV rating of 20 while HEPA type filters have a MERV rating of 15. The difference is very big especially when you are talking about the removal of bacteria and viruses which is what true HEPA filters remove.

Pure Air Systems has been making HEPA based, fan powered air filtration systems since 1985. They use only true HEPA filters in their series of seven different air filtration devices.

Make Sure Your Bakery Smells Like a Bakery

The other day I went to purchase some doughnuts at a new Bakery that opened up in an old strip mall near our house. The other tenants in the building include a bar, fix it shop and automotive repair shop at the end.

Older buildings, especially small strip mall building often had very little barrier between business compartment and odors from one business could and often did migrate into the adjacent store or even businesses two stores away.

This Bakery had that problem. Walking in to the doughnut shop one would think the aroma would be of baked goods. Not this one. It had the odor of un-burned hydrocarbons, oil and something else I could not identify. Fortunately the baked goods did not share that odor but it did make it somewhat unappetizing when I purchased the baked goods.

Pure Air Systems has been making Hepa and Carbon based, fan powered, commercial grade air filtration systems since 1985. These units can move as little as 50 CFM or as much as 2,000 CFM and can operate either attached to an existing HVAC unit or as a stand-alone system.

A 2000 CFM unit could be placed in the odor infected business and both filter out the odors and particulate as well as pressurize the environment to minimize the infiltration of the airborne contaminants. This has been done hundreds of times with the 2000HS units with exceptional results.

The problems facing the doughnut shop are duplicated in strip malls across the U.S. It is especially challenging when your store is next to a Nail Salon or Hair Salon. Odors from the chemicals used in these facilities can actually destroy your business. And trying to get the management to allow you to move to another location may not be possible or not allowed in your contract.

Home Health Care In A Box

The cost of health care continues to rise with much of the higher costs in prescription medicines and hospital treatments. We continue to see more “preventative” ideas for improving your health as you age. It is no surprise that your life style has significant impact on your short-term and long-term health. Excessive drinking, high fat food contents, smoking, lack of exercise and stress are all contributors to affecting your health.

However, one of the other areas that we continue to sweep aside but has a very significant impact on our lives is…the air we breathe.  We ingest thousands of sub-micron airborne particles every day and they come from a wide variety of areas. Grasses, pollen, ragweed, un-burned hydrocarbons, heavy metals, inorganic compounds, soot, dirt and finely ground animal particles.

Pure Air Systems has been around since 1985 making HEPA based air filtration systems for the residential, commercial, medical, institutional and industrial markets. These systems remove a very high percentage of harmful airborne particulate in any environment. Over the past 32 years we have been able to show that there is a direct correlation between living in a filtered environment and the reduction of respiratory dysfunctions, allergies and certain skin irritation issues.

Ingestion of harmful airborne particulate is also dependent upon where you live in the U.S.  The Midwest has a more stagnant air problem with a lot of particulate coming from fossil fuel (coal fired ) power plants and the industrial complex.  The coastal areas tend to get more fresh air as the ocean breezes bring in clean air from the oceans. This is especially true in State like Florida and California.

Use of air filtration in your home and office can help reduce medical costs as they help reduce the potential for health problems directly tied to the air you breathe.

Air Filtration For Your 3D Printer

For five years I have been working with 3D Printers of all types and have printed with over 20 different filaments from PLA to PETG and even Bronze. Some of these filaments when heated to over 205 degrees C to melt them for extrusion give off no noticeable odor Some, like ABS, Polycarbonate and Nylon do emit an odor. Often  a very strong odor.

It is also known that some measure of small sub-micron sized particles are released during the printing process as the extruder moves the heated filament from the nozzle to the build platform. Gases and particulate that are, perhaps,  benign in small quantities but potentially harmful in large quantities or over long terms of exposure.

Pure Air Systems along with its partner, LiteWorld LLC , have developed a plexiglas enclosure with two large access doors that will fit over most large bed 3D printers allowing for two benefits. First, the enclosure has a fan and carbon media filter to capture any odors that might be produced by the materials during the printing process. Second, the unit will significantly minimize the amount of fine airborne particles that are emitted during the printing process.

Air filtration for your 3D printer is perhaps something you don’t think about but it should be on your radar at this point in the evolution of 3D printers. Especially the FDM or FFF printers that use filament in the 1.75 mm or 2.85 mm size range.

The other reason for the use of the enclosure is the safety it provides in keeping little hands out of the moving mechanisms and from the very hot nozzle and build platform. Many schools are now requiring the use of an enclosure to fit over the printer to keep them free from any liability when used in the classroom.

Isolation Room

Isolation is a word that means to separate from or detach from another area in all aspects. Isolation rooms are used often in the medical market to maintain a safe environment from the general public by isolating a dangerous or highly communicable diseased patient from the the general population.

Isolation is more than just separation by walls and doors. In the realm of airborne viruses you require a special filtration method to ensure that any air that is passed between the isolation room and the outside world is properly filtered. This is always done using HEPA based air filtration systems to remove even the smallest airborne particles to eliminate the possible transmission of deadly diseases.

Pure Air Systems has been providing commercial grade, certified HEPA and ULPA filters for a wide range of applications and markets since 1985. HEPA filters have been the only true mechanical filter type that has the ability to absolutely trap the airborne allergens and pathogens that are associated with creating serious illnesses and health issues since the early 1980’s.

Pure Air Systems also makes HEPA systems that can be used in the residential, institutional, commercial, industrial and military markets. After 32 years of being in business Pure Air Systems has well over 10,000 units in the field in both the US and overseas.

Seven different models are available from fan powered air volumes starting at 50 CFM to 2,000 CFM. All the systems use the new variable speed drive motors and they are all rated at, 120/240 volt, 50/60 Hz so they can be used anywhere in the world.

The all metal housings and commercial grade components ensure that these systems will provide high performance service over very long periods of time.  For more information on the complete line of HEPA and Carbon based systems, please go to our website at: http://www.pureairsystems.com  or call us on our toll-free number at: 800-869-8025.

HEPA For Terrorism

We are constantly reminded that we live in a era where anyone at anytime can create mayhem with simple, exotic or well crafted killing tools. There are no limits as to what device a motivated anarchist can do with any of these style devices. Yet, for all the external damage that can be done with hard technology, the invisible, airborne pathogen still creates the greatest threat.

Tiny viruses and bacteria are invisible to the naked eye but can be a major threat to our bodies if these pathogens are inhaled, absorbed or injected into our systems. The only true method of totally removing these objects is to use a mechanical filter such as HEPA. High Efficiency Particulate Air filters have been around since 1940 but their real push into the market came in the late 70’s and early 80’s with the development of the micro-chip.

As HEPA technology improved the types of HEPA paper and testing methods became more effective especially as organizations like the CDC began to work with some really horrible contagions and had to isolate them in special rooms with multiple levels of HEPA filters including the newer ULPA (Ultra Low Particulate Air ) and the new SULPA (Super Ultra Low Particulate Air) filters.

In 1985, Pure Air Systems came onto the market offering true, commercial grade, fan-powered HEPA air filtration systems. This was the first true entry of commercial grade HEPA units into the residential market place. Over the years a total of 7 HEPA systems were produced by PAS and the incorporation of the new ECM motors allowed them to create models that had variable speed motors and that could be sold anywhere in the world.

These systems are considered some of the best HEPA filtration systems in the world and have been used in applications where the facility is being prepared to protect against biological attacks. There is no better filter for removal of harmful airborne pathogens than HEPA.
