Monuments

There is a lot of discussion these days about historical monuments and the issue of whether they should remain or be moved or destroyed. No matter which side you choose the fact remains that these were built for a specific purpose in their time. Many are still standing and a number are now gone.

Many corporations started out creating products that were relevant for their time in the development of our country and it’s industrial base. Over time, many of those companies have either changed completely, went out of business or merged with another larger corporation. Time changes everything.

Pure Air Systems started in 1985 by offering its’ first HEPA based, fan powered air filtration system. At the time it was slightly ahead of the curve as this type of high-end filtration system began to set the standards for high-performance in the area of reduction and/or removal of large percentages of harmful, airborne sub-micron particulate.

Over time, Pure Air Systems saw the opportunity to add larger systems with more airflow capabilities to its product line and began to expand its systems into the commercial, institutional, medical and industrial markets. The addition of the new ECM variable speed motors in 1999 added a new dimension to their product line.

The variable speed motors were magnet driven as apposed to the traditional use of wound motors thus giving PAS the ability to use digital controllers which allowed them to control the airflow in 1% increments. In addition, the motors were rated 120/240 v 50/60 Hz so they could be used anywhere in the world. This propelled the PAS line into another level which lead to the addition of 3 more products to their line.

If PAS was a monument it would probably look slightly different today, 32 years later, than the original built in 1985. Everything changes, nothing remains the same. Technology will move forward in spite of our attempts to slow it down. Time changes everything.

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.

By-Pass Air Filtration By Pure Air Systems

When one sees the word by-pass they often think of heart by-pass surgery or using the business by-pass around a city center.

Pure Air Systems pioneered the use of commercial grade, fan powered, HEPA filtration systems by-pass configurations in the  late 1980’s. Up until that time incorporating a true HEPA filtration system in a residential environment.

Most homes in the U.S. use a ducted heating/cooling systems where the air handler ( air moving device) is located in a basement, garage or closet. Putting anything other than a general duty low efficiency air filter in the return air side of the air handler is not recommended. The high pressure drop or resistance across more efficient filters and especially HEPA filters will significantly reduce the air flow through the air handler and could even have the cooling coils freeze up and/or increase your heating/cooling bills by up to 50%.

PAS came up the the concept of placing their 600HS or larger units in a configuration where some of the air coming back through the main return would be directed into the Hepa Shield system and the balance back to the air handler. Since the HEPA unit has its own blower/motor system this fan pulls the air through the HEPA eliminating any additional resistance that the main air handler blower/motor has to handle. In essence it is a 0 sum addition.

Even though only about 40 to 60 % of the air is going through the HEPA filter system at any one time, over the course of 24 hours all the air in the house has been completed filtered 25 to 50 times. And, if you have a home that is slightly negative then you can introduce a very small amount of outside air into the HEPA unit. A small amount, 50 to 100 CFM , is not going to affect the heating/cooling capabilities at all.

So, with one Pure Air Filtration system, you can create an extremely clean, environment that will significantly reduce airborne allergens, dust and because the systems also incorporated carbon filters, you will reduce house hold odors.

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.

Delta P. The reason you have dust in your house.

With a few exceptions, most homes in the U.S. use some form of ducted heating/cooling system with air returns and registers located throughout the rooms in the house. The central air handler moves air from the returns back to the cooling and heating coils and then moves it back  into the house to either heat or cool the indoor environment.

On the return air side of the air handler where all the returns merge at one point is where the air filter is located. The filter is designed to remove all the airborne dust and dirt that is in the air. Only dust particles in the air that are pulled into the return air grills will be filtered. If the dust particles are too heavy to be airborne they will remain at rest on a surface and never reach the filter.

The HVAC unit in your home is a balanced system. It is designed so that there is slightly more air moving than returning. This helps to keep the house in a positive pressure mode which eliminates in-leakage of cold or hot air. The balance also includes the ability of the blower/motor to move the air throughout the duct work as well as through the air filter. The air ducts and filter all have a resistance known as Delta P or pressure drop. The higher the pressure drop or static pressure the more powerful a blower/ motor will be required.

If the air pressure is balanced with a clean air filter, once the air filter starts to load up the resistance or pressure drop across the filter ( Delta P ) will increase. If the Blower/Motor is not properly sized as the Delta P increases the air flow across the air handler decreases. Once this takes place the amount of air and amount of airborne dust that is in the air will be significantly reduced and you end up with the air handler running more often just to keep the house cool or warm and more dust in the environment.

This is one reason why you need to change your air filter at least once every 6 months and more often if you live in an urban area. For more information on air filtration and how it works please go to our website at: http://www.pureairsystems.com  or call us on our toll-free number at: 800-869-8025.
