Covid-19 HEPA Masks

The Corona Virus pandemic has brought out a cry for protective gear, masks, respirators and ventilators not to mention HEPA based air filtration systems to maintain positive pressure rooms in make-shift hospitals. HEPA filters are made from special paper-like materials that are extremely dense and designed to capture a very high percentage ( usually 99.99% or greater ) of sub-micron particulate. These filters are used in surgery suites, laboratories, chip manufacturing, and any place where airborne particles ( bacteria and viruses ) are present. 

With the Covid-19 pandemic there is a race to provide any type of mask for the first responders, medical personnel and now the general public. This demand has brought out a number of individuals and groups making masks ( or printing them ) out of various materials; mostly cloth of some kind. However, some are offering HEPA masks that look like a regular cloth type mask. True HEPA masks worn by first responders are PAPR masks. Positive Air Pressure Respirators.These masks have true HEPA filters in their design and also have fans to assist in pulling the air through the HEPA filters. These masks are battery powered. Without the assistance of the fan you would would have difficulty pulling air through the mask with your own lungs as the HEPA paper has extreme resistance compared to standard surgical masks. 

The N-95 masks are similar to MERV 8 air filters. They are good for 95% of particles in the 3.0 to 10.0 micron range. Certainly much better than cloth but not as good as HEPA media. The reason this is important is that viruses, such as the Covid-19 virus, can be as small as .0005 microns in size. As a comparison, your hair is about 100 microns in diameter. This sub-micron size makes Covid-19 airborne and allows it to pass through standard mask materials. This is why this virus is so deadly.

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.

Air Filters For Residential HVAC Systems

In today’s fast paced society we often don’t think about common products or processes. We assume that anything we buy or use will operate as indicated and that we should be able to utilize the product with a minimum of effort and retraining. Our home heating/cooling system fits into that category. We turn on the heating or cooling cycle from our thermostat and expect the temperature in the home to match the temperature setting. We do this without much thought. 

When the heating or cooling doesn’t cool or heat adequately we automatically contact our local HVAC contractor rather than even attempt to diagnose the problem by ourselves. While the problem maybe a major malfunction of a component, often times the reason for the lack of cooling or heat is a plugged air filter. 

The blower/motor assembly on your HVAC system is rated at a certain motor horsepower and air flow, as measured in CFM. These are matched systems for the cooling coil and heating system based upon the size of the home. This includes the static pressure the fan sees to pull and push the air throughout the duct system. If the filter is plugged it will take more energy to pull the air through the filter and since the motor/blower assembly is designed to handle a limited amount of static pressure for the CFM it moves. 

If the static pressure capability for the blower/motor is 1.5 ” at rated CFM capacity and the plugged filter adds another .5 to 1.0″ of static load ( which it can do ) it will significantly reduce the air flow through the system as much as 50%. That means it takes much longer to heat or cool your home and it also puts a strain on your system in total. And, it will significantly reduce the ability to remove humidity from the home. Checking the condition of your air filter on a regular basis should be part of your routine.

Pure Air Systems makes a complete line of fan powered HEPA based air filtration systems. We can help you choose the right filter or filtration system for your home to ensure you always have your HVAC system working at its full capacity and that the air in your home is always well filtered.

Pure Air Systems HEPA Filtration System Rescues California Home During Fires

As everyone knows, being around smoke from a forest fire is extremely difficult and dangerous as smoke inhalation can be deadly. For California this past year, the forest fires have been nothing short of horrific. Many homes were lost and smoke hung in the air for weeks in many areas of California.

Pure Air Systems, an Indiana based company, has been making fan powered, HEPA based air filtration systems since 1985. Their systems are capable of being used either in conjunction with an existing HVAC system or as stand alone units. The partial by-pass configuration of the units allow for complete filtration of the home environment while also adding the ability to introduce outside, filtered fresh air to pressurize the home.

A homeowner in the San Francisco area purchased a PAS Model 600HS HEPA Plus system to do just that. His ability to bring in outside air through the 600HS unit and pressurize his home allowed him to stay inside and almost eliminate any smoke or odor from coming into his home. In fact, many of his neighbors also came to his house to escape from the smoke that was everywhere in the SF Bay area.

The 600HS unit has three filters. A dual layer ring panel filter to capture large particles and keep the HEPA clean, a 10 lb carbon filter to remove odors and a scanned 99.99% commercial grade HEPA filter to remove sub micron particulate. Pure Air Systems also makes larger versions of this filtration system ranging from 50 CFM to 2,000 CFM. These systems have been on the market for over 34 years and are the best performing HEPA based air filtration systems on the market today.

Pure Air Systems Moves Into 34th Year Of Selling HEPA Air Filtration Systems

In 1985, Don Musilli founded a company to sell high end HEPA air filtration systems to the residential market. HEPA filtration at that time was somewhat limited to the micro-chip manufacturing industry, asbestos abatement companies, medical operations and some industrial applications. The residential market was using standard pleated, card board box framed general duty filtration media filters or electronic air cleaners. These air filters were located either in the main return air grills or at the point where all the return air entered the main air handler ( HVAC unit ) and were designed primarily to remove very large airborne particles and to keep the cooling coils and fan blades clean.They did little to remove the smaller, respirable sized particulate that could create health issues for many homeowners.

Whether we are indoors or outside, we are breathing air that contains various sizes of particulate. The larger particles. those that you can see with the naked eye, are usually 20 microns in size of larger. ( for comparison, your hair is 100 microns in diameter ). These larger particles are aspirated into our lungs and the majority of them are exhaled out. The smaller, sub-micron particles however, ( those less than 20 microns in size ) tend to stay logged in the lung linings and mucus membranes. These smaller particles may represent a wide range of organic and inorganic materials including pollen, pet dander, ragweed, bacteria, viruses and industrial pollution. For those individuals that suffer from allergies many of these airborne particulate are the primary cause of their respiratory dysfunctions.

Pure Air Systems pioneered the use of HEPA filtration systems with their first model 600H unit.that included a true, scanned HEPA filter rated at 99.99% removal of all particles 0.3 microns and larger, a wire framed ring panel prefilter ( to keep the HEPA clean ) and a true carbon filter to remove odors and gases. These systems were designed to attach to the return air side of a ducted HVAC system using the partial by-pass concept. This unique concept allowed homeowners, for the first time, to use a true HEPA filter system on a residential HVAC unit. These HEPA systems cleane all the air in the house up to 24 times a day and remove a very large percentage of the sub-micron, airborne particulate. 

Thirty Four years later, PAS has added 6 more HEPA, fan powered, air filtration systems to its stable and over 10,000 of these units have been installed in homes and offices across the U.S. and Canada.

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.

Airborne Bacteria Removal and Reduction

For those individuals who live along the South West coast of Florida, this year has been especially challenging with the long last issues caused by Red Tide. This algae bloom is a common occurrence during the summer months and often begins out in the Gulf of Mexico. This year the Algae bloom has been larger and extends from Naples up to Tampa Bay. In addition, the blooms are toxic and kill sea life and produce an airborne bacteria that is harmful and potentially fatal to humans.

In 1985, Pure Air Systems was founded to bring true HEPA based air filtration systems to the residential market. These fan powered, metal housed units, are capable of providing surgery suite environments in all types of buildings and for all types of airborne contaminant applications. These true, commercial grade, scanned HEPA filters can remove up to 99.99% of all particles 0.3 microns and larger.

In the case of the Florida Red Tide issue, there are many days when the number of dead fish on the shore which produce a significant odor and also a release of toxic bacteria into the air which is blown onto shore and into the populated areas when the prevailing winds are out of the West. By applying the HEPA based technology used in the Pure Air Systems air filtration units, businesses and home owners along this stretch of shore line could effectively and safely remove a very high percentage of this airborne particulate and protect the health of those that live and work in this area.

The HEPA based air filtration systems offered by Pure Air Systems consist of small portables with volumes up to 350 CFM to large commercial units with volumes up to 2,000 CFM. PAS also utilizes variable speed drive motors so they can control the air volumes for 1 to 100% in 1% increments to provide the correct amount of air flow for the application. PAS units are used in the residential, commercial, institutional, medical and industrial markets.

Air Filtration For Coastal Areas

If you live on or near the coast line of the U.S. you know the pleasure of looking out over the water and hearing the crashing of the waves and that smell that only comes from being near a body of water. For most people it is very cathartic.

However, with the changing climate conditions and the continued lack of concern over dumping a wide variety of trash into our oceans and lakes, the development of various Algae and toxins is now being found off many coasts.

These toxins are airborne and are harmful to coastal birds, fish and humans. These airborne bacteria range in size from 3 to 10 microns and are not visible with the naked eye. This makes it more difficult to deal with as most people are concerned with what they can see.

In 1985, Pure Air Systems was founded and developed a high end HEPA based air filtration systems that could be attached to any force air ducted heating/cooling system with the ability to clean the entire home 24 to 48 times per day.

PAS uses scanned HEPA filters. These filters are certified to capture 99.99% of all particles 0.3 and larger and up to 99.95% of all particles 0.12 microns in size over time. This means they will remove any and all of the harmful airborne bacteria that comes on shore from the oceans and lakes .

For people with respiratory issues or asthma, these airborne particulate can exacerbate their ability to breath normally without some type of respirator or having to remain indoors when these toxic bacteria are released into the air.

PAS makes a line of fan powered HEPA filtration systems that include a small portable HEPA unit that can move up to 350 CFM of air to our largest system which can move up to 2,000 CFM of air. Except for the portable, the models 600HS, 1200HS and 2000HS can either be attached to an HVAC system or used as stand-alone units. .

Air Filtration For Asthmatics

For most individuals the ability to breathe is so automatic we almost never even think about the process. Only when we are subjected to a high amount of airborne dust or particulate or near smoke do we find it somewhat difficult to breathe.

For people who suffer from Asthma or other respiratory dysfunctions the ability to breathe normally is not taken for granted. They are very aware that at anytime they may suffer from an Asthma attack or their ability to breathe due to either their illness, airborne particulate or both.

Pure Air Systems has been manufacturing commercial grade HEPA based air filtration systems since 1985. These fan powered units are designed to work in concert with any type of HVAC system or as stand-alone units. And, these systems utilize the ECM variable speed drive motors so air volume control can be finite and they can be used anywhere in the world.

The PAS units can be attached to almost any home HVAC unit and provide a very high degree of airborne particulate removal of the size of the particulate that affects those individuals with respiratory dysfunctions.

The HEPA filters used in the line of systems offered by Pure Air Systems are called scanned HEPA filters. These filters have an initial efficiency of 99.99% at 0.3 microns and become more efficiency as they begin to collect the particulate.  You can see a 20 micron sized particle with the naked eye and these particles are normally aspirated in and then expelled easily.  The smaller particles, those less than 10 microns in size are easily trapped in the mucus membranes of the lungs and can cause irritation. These are the particles that create real health issues for those who suffer from Asthma.

Air Filtration For 3D Printing Labs

3D Printing or Additive manufacturing is now the eminent player in the 4.0 Industrial Revolution phase. This technology has opened the door to using materials to make almost anything we can think of and creating a technology that has opened the door for the development of new materials that are developed specifically use in 3D Printing.

Many of these materials are produced by either heating up printing nozzles to temperatures reaching 300 degrees C and above, or by using laser systems to melt metal in the new metal printers or jetting systems that use a wide variety of compounds for creating objects.

All of these systems produce either very fine particulate or significant odors or both. Since 3D Printing or Additive manufacturing is still relatively new, there have not been a lot of studies to determine the levels and size ranges of the particulates that are generated by these machines.

Pure Air Systems has been making HEPA and Carbon based fan powered, air filtration systems since 1985. These systems, ranging is air volume from 50 CFM to 2,000 CFM, are made from all metal housings, using commercial grade HEPA filters and variable speed drive ECM motors. The units come in a number of configurations and control options so they can be attached to any HVAC system , used as stand-alone units and the fans can be controlled to run at any speed.

These systems come with a ring panel prefilter, scanned HEPA certified to 99.99% at 0.3 microns and a large Carbon filter for odors and gases.

In a 3D Printing/Additive manufacturing environment the PAS systems could be used as stand-alone units pulling air from one to four machines and removing the fine airborne particulate. Many newer printers are enclosed so it is easy to attach a small duct to the enclosure and pull that air into the PAS HEPA system.

Another option is to attach the PAS system to the main HVAC units in the lab or production area and remove the particulate and odors using the main HVAC ducting system to pull all the contaminated air back to the filtration unit.

The Pure Air Systems HEPA units have been used on almost every application requiring filtration in almost every corner of the world. They have been used in applications where toxic gases and dangerous airborne particulate are present. Their rugged durability and history of high performance over long periods of time are the reason Pure Air Systems has been in business for 33 years.
