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.

Coronavirus and HEPA Filtration

Viruses are very tiny microbial particles. They are less than .012 microns in size and are easily transmitted by air or touch. The masks that people are wearing to protect themselves from this virus. Unfortunately this is just not the case.

In order to remove viruses from the air you need some very special HEPA type filters. These are called SULPA filters. This stands for Super Ultra Low Particulate AIr or Absolute filters. These are used by the CDC and other medical clinics around the world. Most of the masks now worn by people for protection are not capable of removing any viruses and most bacteria. They are good for removing large dust particles. HEPA masks are available but very expensive and hard to breathe thru as the HEPA paper is very dense and creates a lot of air resistance. 

Pure Air Systems has been making HEPA based, fan powered air filtration systems since 1985 and has a number of HEPA filter systems that are designed for residential, commercial, institutional and medical applications. Their portable unit is certainly one of the best on the market for reduction/removal of harmful airborne particulate including bacteria and some viruses. Their systems can be attached to existing HVAC units or used as stand-alone systems.

Pure Air Systems To Be Highlighted In Pharmacy Practice Magazine

Pure Air Systems has been making commercial grade, fan powered HEPA based air filtration systems since 1985 and has seven different model and size configurations to fit any commercial, medical, industrial or residential application for reduction and/or removal of sub-micron airborne particulate. Recently, GOTO RX, a company based in Ontario, Canada that specializes in pharmacy clean rooms and other products for the pharmacy industry, recently purchased a 2000HS HEPA filtration system from Pure Air Systems to tests it’s effectiveness using a smoke test by the College of Pharmacists, Air Quality test protocol. The unit was mounted in the ceiling of two clean rooms with short duct runs to a number of inlet points to capture the smoke that was generated by the testing equipment.

William Fretwell, President of GOTO RX provided this description of the smoke test and the results. The 2000HS was tested at a flow rate of 43% of maximum ( 2000HS can move up to 2,000 CFM ) with a room  air change rate of 45 air changes per hour which is above the 30 changes per hour normally required for this type of clean room. So there was lots of spare capacity. During the smoke test where a special chemical is used to generate smoke that is extremely fine with much of it invisible to the naked eye, the particle counter found no smoke passing through the Pure Air Systems HEPA unit. The 2000HS created a clean room environment in both rooms with a Clean Room rating of Class 6, which is 10 times cleaner than the required standards. William Fretwell commented that, ” most hospitals don’t have anything up to this standard”.

As a result of the successful test results, GOTO RX is planning on publishing an article for Pharmacy Practice Magazine with the title, “The New Clean”. It is important to note that PAS has been using their HEPA based filtration systems for over 35 years in a wide variety of clean room type applications with superior results.

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 Filtration For Pot Growers

The use of Marijuana for both medical purposes and recreational use is growing across the U.S. There are now only 15 states where it is fully illegal.  In 12 states you can legally smoke pot and many other states allow it for medical use. Not to be punish, but the growth of pot as a sustainable business is exploding and the states that have made it legal are reaping the rewards in the form on increase tax dollars going into their coffers. 

Back in the early 1990’s Pure Air Systems, a company that makes high end HEPA  and Carbon based, fan powered air filtration systems, was asked to provide an all carbon filled 2000 CFM unit to a Florida police station to help remove the odor from the Marijuana stored in their evidence room. The odor was very strong and filled the entire police station. The system worked very well and to this day that Police station continues to order replacement carbon media for that unit.

Massachusettes, one of the states that has made pot legal, has a number of new pot growing operations now being built in that state with some at large as 1 million square feet. The goal of these operations is to produce a very high grade marijuana product so that their yield per acre is better than their competition. The better the grade the less weed you need to obtain the desired effect.

In order to accomplish this goal, these pot growers are ordering a large number of Pure Air Systems largest model ( 2000 HS ) to both filter the air coming into the building and the air exiting the building. On the inlet side, they are using the 2000 HS units with HEPA filters to significantly reduce the amount of airborne contaminants from entering the grow space that could inhibit the growth and purity of the pot strain. On the exit side, they are using the 2000 HS but without any HEPA filter. These units are usually desingated as 2000 OA units as they contain only Carbon media. These significantly reduce the odor being produced by the grow house operation. Almost identical to the application of these systems in the early 90’s at the Florida Police station.

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.

Portable HEPA Filter Systems For Any Application

There are many commercial and institutional applications where a true HEPA filtration system is required but space and time of need is limited. Pure Air Systems, based in Indianapolis, manufactures a complete line of HEPA and Carbon based, fan powered air filtration systems that range in air flow capacity from 50 CFM to 2,000 CFM. These systems use high end blowers and motors and are framed in all metal housings.

The HPS model portable units from Pure Air Systems have a four speed motor/blower, a ring panel prefilter/carbon media filter and a true, scanned HEPA rated at 99.99% at 0.3 microns and larger. These portable units are 13″ square by 24″ long and weigh only 34 lbs. These units are very powerful and can move up to 250 CFM of HEPA filtered air. While these units are often used in small laboratories, hospital rooms, nursing homes, clinics and mobile trailers, they are a perfect filtration system for the home and office. 

The powerful fans allow you to use this system either as a stand-alone system or attached to duct work so they can move air through a fairly large area and can also be used to provide positive or negative air pressure in any enclosed space. The PAS HPS series are the most powerful portable HEPA units on the market today and the average length of time in service of 15 years.

Pure Air Systems also offers a complete line of HEPA based systems that are designed with unique configurations so that you can install a unit in any location with the ability to have the inlet and discharge in any direction for best installation and performance. PAS offers 7 different orientations for all of its systems with the exception of the portable unit.

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.
