Air Apparent

Pure Air Systems is now 32 years old and is one of the remaining few companies in North America that still makes high end, commercial grade, fan powered HEPA air filtration systems. These systems are designed to provide true HEPA filtered air in a wide variety of applications including but not limited to: commercial, industrial, institutional, medical and residential.

Pure Air Systems makes only one type of HEPA based air filtration system so the residential customer receives the same identical system as the hospital or laboratory. These systems are designed to last a long time and run for years with minimal maintenance other than changing any one of the three filters at regular intervals.

There are a number of models available designed to fit any application and with the ability to be either installed as stand-alone units or being attached to the return air side of any HVAC system; commercial or residential.

Pure Air Systems is now the Air Apparent in this industry as there is only one other company in Europe that makes fan powered HEPA air filtration systems with the ability to handle air flows from less than 50 CFM up to 2000 CFM in a small housing configuration. In addition, the PAS units utilize the newer ECM variable speed drive motors that are rated 120/240 volt 50/6 Hz motors so they can be used anywhere in the world.

Each system has a prefilter, carbon media filter and true HEPA  filter. The systems can be configured to have all Carbon media with one prefilter for applications where only odors and gases are present. Or, they can be configured with two prefilters for applications where high levels of large particulate are present.

Hookah

In the song “White Rabbit” but Jefferson Airplane, Grace Slick sings about a smoking caterpillar that approaches Alice. The caterpillar is called a hookah. I don’t believe that is the name of the caterpillar as a hookah is actually the water pipe he was smoking. But the lyrics make more sense with that sentence structure. It is interesting how we often sing song lyrics and never pay attention to the meaning or even if a word is correctly used in the lyrics.

Sometimes companies use words in their marketing propaganda or as part of their packaging that are, ,more often than not, misleading.  The words absolutely or guaranteed are used to express a sense of perceived satisfaction that the customer will experience when they use the product. But we know that is not often the case. Yet companies still use this marketing process to garner more business and hopefully new customers.

One of the main challenges with raising expectations for one’s product or service is the delivery. That is, if you promise one thing, but deliver another,  the customer will probably not purchase that product or service again. Funny how companies still believe that words have more power than performance. It is also a big mistake to mislead people as the use of social media now has so much power that one bad experience can be pushed to hundreds of thousands of people in a matter of minutes.

Pure Air Systems has been manufacturing and marketing HEPA based, fan powered air filtration systems since 1985 and since the beginning it has marketed its line of commercial grade filtration systems as ” The Best Filtration Systems In The Market”.  Performance has always been its main promise and through its 30 years life has consistently performed at or above the expectations of its customers. Using the more expensive, commercial grade components, keeps PAS in the lead in the area of high performing HEPA systems.

Over the years PAS has added more products to its line, all of them using the same high performance components and fabrication techniques to ensure that customers buying any one of the systems would be completely satisfied with the product and its performance.

A Horse, A Chicken And A Dog Walk Into A Bar!

This set up line for a joke is iconic.  Anybody who has ever heard a joke or told a joke knows one of these “three guys walk into a bar” type jokes. As soon as someone starts to use this style of humor you automatically think of one you heard recently or like to tell. And, sometimes you can guess the punch line even before the joke is told….making this type of set up a powerful memory trigger .

For many people these “trigger” or ” anticipation” moments are not of the humorous type but based  more on fear or concern. For example, take someone who has severe allergies to pollen, ragweed, grasses, etc. When Spring approaches and they start to see flowers blooming and trees and grass growing they anticipate that they will start having the typical allergy symptoms of itching eyes, running nose, sinus pressure and and all around crappy feeling.

Sometimes just watching the news at night and seeing the projected pollen count for the next few days can trigger an emotional response that almost mimics the physical symptom response. This person knows that even with the over the counter allergy medications or shoots from the allergist, as long as the grasses and trees are growing they will suffer.

Allergy medications tend to make people groggy and have difficulty concentrating on anything. This is why for most allergy sufferers the best solution to minimizing the suffering is to stay indoors preferably with the air conditioning running. And, when possible use some form of air filtration or air purifying device to assist  in removing the airborne allergens and particulate.

Pure Air Systems has been making HEPA and Carbon based air filtration systems since 1985 and has thousands of its systems installed in homes, hospitals, commercial buildings, high tech manufacturing and specialty applications. For many of the homeowners the HEPA systems significantly help to minimize or eliminate that allergy “trigger” so the individual can be comfortable not suffer even when they watch the news and the ever climbing pollen count projections.

Ion Generators – Why They Don’t Work!

For the past 30 years a number of technologies have been tried in the attempt to remove airborne particles. A wide variety of air filtration systems or air purifiers have been developed and marketed with claims of total removal of harmful airborne contaminants and with no need for any type of air filter; using only simple techniques.

Two of the most common air purification devices that fit this description are air Ionisers ( or negative ion generators) and ozone generators. Ion generators use high voltage to electrically charge air molecules. Negative ions are particles with one or more extra electrons. Ozone generators are designed to attract an extra oxygen ion to an O2 molecule, using either a corona discharge or UV light.

Ozone generators were discussed in one of our previous blogs, so this blog will discuss the pros and cons of using ion generators as air purifiers.

Air ionisers work in this fashion. Airborne particles are attracted to the electrode in an effect similar to static electricity. These ions are de-ionized by seeking earthed conductors, such as walls, ceilings, nails in walls, etc. In essence the airborne particles are negatively charged and then find a positively charged surface and stick to it. (basic high school physics)

Perhaps another way to view this concept is to think about running a comb through your hair and then placing the comb next to tiny pieces of paper and watch the paper stick to or be attracted to the comb. This is how the ioniser works. Negative Ion Generators are also referred to as Ionizers (spelled with a z)

Here is the challenge with this technology. In every home and enclosed occupied environment there are always particles floating in the air. For the most part you can’t see these particles because you can only see particulate that is 20 microns in size or larger with the naked eye. Almost all of the airborne particles ( very light) are less than 10 microns in size (many less than 5 microns) and invisible to you.

For discussions sake let’s say that you can see all these airborne particles in your home as dark floating particles. When you turn on the ionizer the negatively charged air molecules will attach to the particles and then attach to or “plate out” to the walls, ceilings and any other surface. So now the dark particles are no longer airborne, they are now on the walls and other surfaces.  They have not been removed from the room, just moved to another location.

The issue here is that negative ion devices are marketed as air purifiers, making the assumption that these systems will actually assist in removing or reducing harmful airborne particulate without the use of any filtering component or device. Nothing could be further from the truth. Once the electrical charge on the particle has dissipated, the particle becomes airborne again.

The only way the ionizer can be effective is to use it in conjunction with a air filtering device that actually uses a mechanical media filter. Otherwise you will never capture the particulate.

Pure Air Systems makes a complete line of HEPA based and media based air filtration systems and mechanical air filters. The new HPS series portable HEPA units are extremely effective at completely removing harmful airborne particles as small as .012 microns.
