Cigarette Smoke Removal

I have written over 100 articles and blogs on the subject of removing cigarette smoke and odor from any indoor environment and the resolutions we have today are the same as those proposed 30 years ago.

The best and most effective method of removing smoke from the indoor environment is to eliminate any smoking in indoor environments. It’s just that simple. Removing it using air filtration, air dilution, carbon filters and high volume fans is only a band-aid approach at best.

Once the cigarette smoke sticks to any surface it will re-release that odor for days. It requires a strong solvent based cleaner to remove the brown tar material that is present on the walls of a smoking environment.

Pure Air Systems has been around since 1985 producing high capacity, commercial grade, certified HEPA and Carbon based fan powered air filtration systems for the residential, commercial, institutional, medical and industrial market place. Many of these systems were sold for the exclusive purpose of removing cigarette and cigar smoke from indoor environments.

The degree of effectiveness of the systems was directly proportional to how much smoke we could remove at the source over time. And, the cigarette smoke will clog up a prefilter in two to three weeks and the HEPA filter in less than 3 months. The Carbon media in the units which is designed to remove much of the odor, would last perhaps 4 to 6 weeks at best. In essence, it is very expensive and difficult to remove the cigarette smoke and odor with any degree of effectiveness.

It is for this reason that smoking is prohibited from most buildings, hospitals, schools, airports, planes, trains and ships. Aside from the environmental issues smoking is also extremely harmful to your health.

Air Filtration For Dummies

The device that you or your HVAC contractor changes once or twice a year is designed, primarily, to keep the cooling coils clean. It has very little effect on the removal of airborne particles that maybe harmful to your health.

These general duty air filters are comprised of very open mesh or pleats that allow air to pass through easily but capture larger dust and dirt particles to minimize any deposit of dirt on the cooling coils which could, over time, significantly reduce the efficiency of the coils and also put dirt on the blower wheel.

Dust particles you can see are about 20 microns in size or lager. As a comparison, your hair is about 100 microns in diameter. However, airborne particles that may harm you body when inhaled are usually smaller than 1 or 2 microns in size. The efficiency of the general duty air filter on these sized particles is about 25% at best. Meaning your health is not protected in any way from indoor airborne contaminants with these general duty filters.

Perhaps the best way to get some real basic information on how filtration actually works is to go to the Pure Air Systems website. ..https://www.pureairsystems.com  There you will find a section entitled “Pure Air University.” This is broken down into simple sections detailing how filtration actually works and the reasons why you may want to look beyond the general duty filters if you really want to clean up your environment.

PAS produces high end HEPA based, fan powered, air filtration systems and has since 1985.  32 years of experience in working with all types of airborne contaminant applications allows them to share their experience and knowledge of this process with anyone who cares to go to their website.

Climate Change Particulate Effect

Climate change is more than warming of the earth or oceans at an unprecedented rate, it is the change in atmospheric conditions that alter the environment in every way. In places where the usual amount of rain has been dramatically reduced, the levels of airborne dust particles is increasing. Walking on or driving on packed soil creates tiny sub-micron particles to be released into the air at a faster rate as there is less moisture to keep the soil intact upon impact.

These airborne particulate consist of both organic and inorganic materials some of which can be harmful when inhaled in small quantities over a long period of time. While our lungs can usually handle particles that are 10 microns or larger, the smaller particles tend to get trapped in the lung linings and mucus membranes and are slow to be released.

In 1985 Pure Air Systems was formed to produce and sell HEPA based air filtration systems for the residential market. In the past 30 years, PAS has grown from one system to seven and now provides true, commercial grade, HEPA systems to the commercial, institutional, industrial, medical and residential markets and sells its’ systems all over the world.

While homes and buildings have developed a much better process to keep them close to air tight, the higher levels of sub-micron particulate are still present in the buildings. More importantly, these particulate are at very high concentrations when the air is stagnant or on hot, dry days. The PAS HEPA systems have proven themselves to be  extremely effective at removing 99.99% of all particles 0.3 microns or larger and close to 99% of smaller particles.

Extreme weather produces extreme environmental conditions and it is important to understand the relationship especially if you live out west in the dryer climates.

Capturing Odors and Particulate From 3D Printers

3D Printers have been on the market now since 2010 and the use of the FDM or FFF style 3D printers that use filaments made from a wide variety of materials are the most commonly used in schools, libraries, small R&D labs, business and homes.

Some of the materials that are used in the printing process such as ABS and Carbon Fiber produce significant odors and in a small room this can be very noticeable and unpleasant. In addition, small, sub-micron particles are released into the air during the printing phase. These particulate are too small to see with the naked eye but can become an irritant to those individuals who have allergies or have some form of respiratory dysfunction.

In order to remedy this issue, should it present itself as a problem, one option is to enclose the 3D Printer to contain the odors and particulate and the second is to connect a filtration system to the enclosure to effectively remove the odors and remove the airborne particulate.

LiteWorld LLC makes a large plexiglass enclosure with aluminum frame and large access doors that will fit over the larger open 3D printers such as the LulzBot TAZ 3D Printers. These enclosures can be purchased directly from LiteWorld by going to their website at: http://www.liteworldllc.com or contacting them by phone at: 941-999-8200.

Pure Air Systems makes the HEPA and Carbon based air filtration systems that can connect to one or multiple enclosures to both remove the odors using the Carbon filters that are included in the systems and remove the particulate by using the commercial grade HEPA filters. These high end systems, coupled with the LiteWorld enclosures will provide an almost clean room environment for your 3D Printer operation.

Creating Negative Pressure With HEPA Filtration Systems

Pure Air Systems started making HEPA based air filtration systems in 1985. Today they are one of the leaders in HEPA filter technology with over 7 different fan powered systems ranging in capacity from 50 CFM to 2,000 CFM.

In the 60’s and 70’s Asbestos removal was a very big industry as older homes and builders were gutted to remove the harmful asbestos materials. In order to keep the asbestos fibers from flying around and getting out into the open areas or outside the contaminated space, the areas being cleaned up were enclosed in 3 millimeter thick Polyethylene sheeting. Large, fan powered HEPA systems were placed outside the containment area pulling air from inside the containment area creating a negative pressure inside the cleaning zone.

The HEPA filters would trap any of the Asbestos particles and when you entered the containment area through a zipped door air would move into the zone rather than come out of the zoned area.

In the medical field when patients are considered to have a highly communicable disease, they are often placed in rooms that are kept under negative pressure again using fan powered HEPA filter systems. This ensures that any viruses in the room stay in the room.

These same techniques are used by the CDC or WHO when they are working with deadly viruses and bacteria. The rooms where they experiment with these pathogens are tightly sealed and under negative pressure with the air passing through multiple layers of HEPA filters using HEPA, ULPA and SULPA filters. The rooms are designed so that the doors will not open unless the air handlers and HEPA systems are in operation.

HEPA filters are made from very dense media and they have a lot of resistance so larger motor /blower units are required to move air through the HEPA filters. HEPA filters are the only filters capable of removing particles as small as 0.12 microns at levels approaching 99.99995%.

Pure Air Systems HEPA Air Filter Systems

HEPA filters have been around since the development of the Atomic bomb in New Mexico in the 1940’s. Originally designed to remove radioactive alpha particles to protect the engineers at Los Alamos, HEPA media or paper is extremely dense and has the ability to trap sub-micron sized particles at levels approaching 99.9995%. In the case of the technicians in New Mexico, these filters were life savers.

In 1985 Pure Air Systems was formed to provide true HEPA based air filtration to the residential market. The initial unit, model 600H, had a 12″ x 12″ 10″ high metal framed HEPA filter the fan was powered by a  1/3 HP induction motor. The unit would produce up to 600 CFM of HEPA filtered air.

The initial marketing for the product was challenging as HEPA was not a common filter media used in the residential market in those early years. The market grew as more people demanded by whole-house filtration and wanted to get away from the standard furnace filters that really did nothing to remove the levels of harmful sub-micron particulate in the air.

Fast forward to 2016. PAS now offers 7 different HEPA based air filtration systems ranging from the new HPS portable units up to the 2000HS unit that can move up to 2,000 CFM. In addition, PAS now uses the newer ECM variable speed motors that allow for use in any country around the world. These are 120/240 v 50/60Hz magnet driven motors that also adjust for the increased pressure drop across the HEPA filters as they load up with particulate. These motors are also more efficient and offer variable speed control to their owners.

Today, Pure Air Systems has filtration systems in every area of the market including, the commercial, institutional, medical, food, beverage, industrial, electronic and residential. All of the units come standard with one prefilter, one HEPA unit and one carbon filter. They can be reconfigured to have only carbon media or or two carbon filters and one HEPA filter.

Pure Air University

When evaluating a product for which you may have little knowledge it is always good to get some objective information from a reliable source. The company from which you want to purchase the product will have a lot of sales data and list the benefits and features but little about the technology used in the design and operation of the product.

The philosophy of many companies is to list features that people will recognize and not confuse them with the technical specifications.This allows for more reading space to sell the product and show the applications.

Selling air filtration systems can be challenging especially when you now have a standard that is used when rating the efficiency of the filters. The MERV ratings are used to provide the consumer with some idea of the overall effectiveness of the filters based on a percentage of removal of certain size particulate. The ratings start at 1 and go 20 with the higher numbers meaning better efficiency at removing smaller airborne particulate.

Most furnace filters are in the MERV 4 to MERV 7  ratings. These are general duty filters and they are good at taking out large particles with minimal air flow resistance. To remove a very high percent of those particles that are sub-micron in size and the most harmful you need a MERV 20 filter.

Pure Air Systems has an in-depth archive in their “Pure Air University” section that goes into depth on the technology behind air filtration, both mechanical and electronic. With this information you can better determine the type and size of air filter or filtration system required for your application or specific health issue.

HEPA Filters are rated MERV 20 and as shown in a MERV chart  and are the best mechanical filter for use in applications where sub-micron particulate needs to be removed. These units are used in medical, institutional, industrial, commercial and laboratory applications.

The Shallows

I recently rented the movie ” The Shallows” staring Blake Lively playing a stranded surfer on an island in Mexico where she tangles with a very large shark.  The Shark won’t let her get back to shore after she inadvertently got on a small whale that the Shark had killed thinking she was taking his food.

Surprisingly the movie was good although I believe the Shark would not have been so aggressive in real life. It is always fun when movies take an idea and give it enough truth to be able to sell the unbelievable parts.

Companies often do the same thing when marketing their products. They spin the benefits and features as being the most effective and best performing of any product of its type on the market and show you a video proving their claims. Only the video, like the Shark movie, is slightly to the left of the truth. We all want to believe that what someone is telling us is both accurate and the truth. It is getting harder today to distinguish the truth from fiction.

Performance tends to be the best way to judge the merit of a concept, idea, product or even a movie. With the use of social media as the primary method of exchanging information these days, people are very quick to send out a  review of a certain product, restaurant, movie, play or people in politics. The upside is that a quality product that works well as promised will get a significant amount of positive comments by the masses. Conversely, if the product fails to live up to its performance guarantees, then a huge number of people with eviscerate the company or the product through the internet. And all the TV and newspaper ads won’t stop the bleeding.

Pure Air Systems started its company in 1985 on the premise that it would produce the highest quality, best performing products for the air filtration market. The HEPA and Carbon based, commercial grade, fan powered air filtration systems by Pure Air Systems are considered one of the best in the world today. This did not happen by accident.

Meeting the ever-changing needs of the market place is difficult. PAS has managed to do this by continuing to develop products asked for by the commercial market and consumers alike. They sell performance and reliability on a daily basis.

Comprehensive Coverage

When purchasing insurance for home or auto you often look at the section marked “Comprehensive Coverage.” This tells you what is covered under the policy with the price quoted to you. This can include covering medical costs, with certain dollar limits, uninsured motorist, which is good to have and a number of other conditions. It does not, however, cover acts of God, which include Aliens crashing their space craft into your car or large creatures eating your seats while you are parked outside your favorite restaurant. No..Comprehensive does not really mean Comprehensive.

HEPA, high efficiency particulate air ( absolute) filter labels do not necessarily mean that this is a true HEPA filter.

In 1985 Pure Air Systems opened it doors offering their first true, commercial grade HEPA filtration system in their model 600H. These metal framed, scanned, 99.97% at 0.3 microns were the most efficient HEPA filters at the time. Fast forward to today and Pure Air Systems offers the same HEPA filters only these are all rated at 99.99% at o.3 microns and work well in the industrial, commercial, institutional, medical and residential markets. In truth, these filters offer Comprehensive Coverage.

The reduction and/or removal of sub-micron airborne particulate is extremely important in many process and medical applications.Hospitals use 100% HEPA filtered air in their operating rooms to reduce the high risk of infection and all clean rooms that manufacture micro-chips use multiple levels of HEPA and ULPA filters to obtain particulate free room levels down to 99.9995% at 0.12 microns. These are normally listed as Class 10 clean rooms.

In the world of filtration, nothing is as effective in removing harmful airborne particles as HEPA filters. All the CDC labs in Atlanta and WHO facilities around the world use HEPA filters to reduce the potential release of extremely virulent bacteria and viruses as these pathogens can often be deadly.

Reducing Odors In Your Home

Odors can trigger memories that are both pleasant and repulsive. You walk into your old school building and it has that same smell you remember as a young child and it instantly brings back memories of your days at that institution. You open up the trash can lid that is full of garbage and the odor instantly reminds you of the days you worked in landfill in the summer between college semester.Both odor are significant. One positive and one negative.

Our olfactory senses are more keen than our visual processes and smells and odors often affect us more than what we see.

In 1980 Pure Air Systems was formed to provide high performance, fan powered air filtration systems that would incorporate both HEPA filters and Carbon media. The HEPA filters remove a high percentage of sub-micron particulate and the carbon media removed a large percentage of odors and gaseous pollutants.

It is difficult to see any airborne particle that is smaller than 100 microns in size ( about the diameter of your hair) so it is often difficult to know if the HEPA system is actually working. If you suffer from allergies triggered by airborne pollen, ragweed, etc. and you notice that while you are in your air filtered living environment that you have fewer issues with your allergies then one can assume the filtration system is working. When you have specific odors in the house, be they animal, cooking or smoking odors, a significant reduction or removal of the odors is notice immediately upon entering that room or living environment.

The systems manufactured by Pure Air Systems can incorporate up to 60 lbs of granular activated carbon in replaceable 15 lb framed cartridges. The smaller unit can carry up to 30 lbs of carbon. These high density, high capacity systems can significantly reduce odors and gaseous pollutants in commercial, institutional, industrial, medical and residential applications.

Typically these carbon filters need to be changed on a 3 to 6 month basis depending upon the nature of the odor and the amount of time the systems are running. For most home applications 6 months is a good change out frequency. These systems can be attached to an existing, ducted HVAC system or used as stand-alone units. The variable speed ECM motors used in these systems allows for incremental control of the speed and air flow.
