1. Introduction This manual has been prepared especially for use by all Dealers on aspects of air filtration, which we are sure will be of benefit to all who will use it. A knowledge of the current filter test methods and standards covering air filtration for general indoor air quality is necessary when comparing and selecting our next-generation air filter technology. 1.1 The Need for Filtration The air we breathe is a mixture of gases, principally Oxygen and Nitrogen. It also contains particulate material and gases generated by nature, by man and by industrial processes. Principal sources of this contamination are particulates generated by construction and demolition, carbon, oil and exhaust fumes from traffic and other combustion processes, such as fly ash from stack and chimney emissions. Natural causes are elemental erosion of the landscape and buildings as well as eruptions etc. Others include sea salt, sand, pollen, moulds, bacterial spores. More localised sources of dust are ourselves, generated by the shedding of skin, and fibres from the clothes we wear. Basically, the air that surrounds us is not clean. We are concerned with the particulate matter and gases which influence our health and comfort, which affect the spaces we occupy, the products we manufacture or the equipment we use. Regardless of it's source, an airborne contaminant is classified as either an aerosol or a gas. An Aerosol is a suspension of solid or liquid particles in the air. There are different aerosols depending on how they are generated. Dusts are solid aerosols generated by the reduction of larger solid materials. Typically large dust particles (those greater than 10.0 microns) settle rapidly and smaller dust particles (in the range 1.0 to 10.0 microns) tend to stay suspended in the air by currents or to settle very slowly. On the other hand, particles in the range 0.1 to 1 microns have negligible settling velocities. Our Next-Generation Air Filtration Media covers everything from 0.1 Micron and above.


Fumes are solid aerosols formed by the condensation of vapours of solid materials, such as are caused by an arc welding process. Very small fume particles tend to agglomerate forming larger particles. Fogs are liquid aerosols formed by the condensation of water vapour. Mists are liquid aerosols formed by the atomization of liquids. Smokes are liquid or solid aerosols formed by the incomplete combustion of organic substances. Gases are materials existing as molecules, which have the tendency to expand indefinitely to uniformly fill the container, or space they occupy. Gases are formed in chemical processes where they are deliberately prepared for other uses or where they may be the unwanted by-products which are either leaked or vented deliberately through stacks or chimneys. Gases which can be of particular nuisance are also formed as a result of the more obvious biological processes relating to sewage, and from plastics and other materials used in the manufacture of household items such as furniture and floor coverings. Vapours are gases formed by the evaporation of materials which are normally solid or liquid. 1.2 Size of Contaminants General The unit of measurement which is appropriate to air filtration technology particle sizing is the 'micron', or micrometer. (see 2.1) What is not normally considered is the aspect ratio of particles, that is the ratio of length to diameter. If for example a particle is 10 microns long and 1 micron wide, it will be assumed to be a ten micron particle. Few particles are spherical, most are irregular in shape and form and vary between crystalline and fibrous. The smallest particle which can be seen by the human eye without the aid of magnification is approximately ten microns. More than 99% of the particles which are present in the air are below one micron. Particle concentration: In the average industrial area there are around two and a half billion particles per cubic foot present in the air, although the levels of concentration will vary considerably depending on location, elevation and season. (See attached chart) Particle sizes of between 0.3 and 50 microns will normally be considered when making a filter selection.


Here is an image of particulate sizes:

1.3 The Importance of Air Filtration

Air filtration provides the means of obtaining the level of particulate cleanliness required;

a) To prevent the ingress or emission of hazardous substances.

b) To reduce and stop odors from permeating

c) To reduce COPD, Asthma and Allergies

d) To provide healthier and more comfortable living and working conditions for occupants of buildings.

e) To reduce the risk of infection in hospital 'critical areas' or other related environments.


f) To prevent the contamination of foodstuffs, pharmaceutical products and delicate electronics during manufacture.

g) To prevent the build up of contaminants on heater or condenser coils and other ventilation system components.

h) To protect expensive or delicate machinery from avoidable wear and subsequent

maintenance and/or replacement. 1.4 General Air Filtration In general air filtration takes place in one of three scenarios.

1) The filtration of atmospheric inlet air to a system, process or occupied space

2) The filtration of internally re-circulated air and the filtration of exhausted air from the system

3) Process or occupied space to the atmosphere. The need for filtration is therefore unquestionable and consequently the vast majority of applications relate to inlets for ventilation, air conditioning and process machinery. 1.5 Filtration and Indoor Air Quality (IAQ) Much has been said and written on the subject of IAQ, and in particular, Sick Building Syndrome, or SBS. Air filtration cannot solve SBS, but it has a major role to play in making improvements. Listed below are the main problem area's relating to SBS which are associated with filters and filtration systems: Poor quality filters being used. Poorly designed systems: a) Inadequate sealing b) Incorrect selection of filter types c) Incorrect filter performance Lack of maintenance procedures and schedules Lack of filter monitoring


Most of an air conditioning system is hidden from view. There could be many metres of ducting in an office, process, factory or hospital where dirt can collect or germs breed. One indicator of a contaminated air handling system is visible dirt on diffusers and associated stained ceilings and walls. However, as bad as this is, the worst harm can come from the reduction in efficiency of the plant. i.e If the fans and coils become coated in grime and dust, the result can mean greater energy consumption and reduced performance. Also of concern is the effect on safety equipment. Automatic fire dampers can become clogged, and if there is combustible debris in the ducting, the ventilation system can be turned into a fire hazard. If dirt is present in the system it is a major exercise to clean the ductwork, which can be very expensive. The main precaution within an air conditioning system to control air quality and halt the ingestion of contaminants is the installation of the correct grade and quality of filters. Filters are not a 'fit and forget' item and will require maintenance at regular intervals, which will entail replacement. If filters are to do the job for which they are designed, all the air must pass through them. Damaged, ill-fitting or missing filters will allow the bypass of unfiltered air, which defeats the object of their installation. 2.0 Introduction to SFC Air Filter Sanders Filters Canada - A full service company providing custom sized submicron air filtration to the residential and commercial sector in Canada. Custom fit for your return vents, intake vents and main ventilation to offer you better than HEPA-quality clean air for any indoor environment. 2.1 Overview of product and capabilities Finally a practical and economical solution exists to generate the highest sub micron air quality without expensive system upgrades or retrofits. Our Next-Generation Filters are 99.97% efficient at 0.1 micron level which captures all of the typical airborne contaminants including all bacteria / mould and many viruses. These filters are soft, flexible pads which can be cut to any size or shape and have low static pressure unlike typical rigid micro fine filters. The differences between our Micro-bial Containment Filters and other products make the choice simple.


SFC Air Filters are: • Effective

• Environmentally Friendly

• Economical Cost

• Effective

Sub-micron filtration is now possible for any critical area or entire buildings without expensive HVAC system upgrades or retrofits. Our Microbial Containment Filter can capture and hold the most common airborne contaminants and pathogens including Influenza A, H1N1, dust, mold, and other particles with each exchange of air in the room. These filters are safe and effective for use anywhere airborne contaminants are a problem including: • Schools

• Hospitals/ Clinics/ Doctor’s Offices

• Day Care Centers

• Assisted Living and Nursing Homes

• Hotels/ Motels

• Private residences

• Commercial office spaces

• Retail stores

• Passenger compartments in commercial airliners

Microbial Containment Filters are supplied in both pre-cut sheets and in rolls and may be installed on the outside of existing vents or just behind any wall or ceiling vent.

2.3 UL Canada Approval Here is the Fire & Smoke approval for use in Canada. As you will read our Next-Generation Air Filters are beyond safe. Smoke Air filters are allowed 9 square meters of Smoke Area when lit on fire. That is almost the size of a bedroom.

• Our filters emitted 0.00 and 0.01 square meters of smoke during the test. Fire / Spark Air filters are allowed no flames and less than 25 sparks during the test

• Our filters had no sparks emitted


2.4 Demonstration Equipment Needed

The Following items are needed to demonstrate the effectiveness push the most sales with our air filtration product. Laser Particle Counter

Model: DC1700 BATTERY OPERATED (firmware v2.05f) – calibrated for 0.3 micron $525.00 USD plus shipping

***REQUIRES CALIBRATION CERTIFICATE*** **REQUIRES CE MARK** http://www.dylosproducts.com/dc1700.html

Sample Box Fan Filter

Simple box fan from Walmart or Canadian Tire with a piece of our Air Filter wrapped around the entire fan. Turn the fan on its lowest setting and place into a room. To learn how this works it is recommended going into a room in your house first.

• Take readings with the Particle Tester. • Put the filter fan in the room walk out

and come back 20 minutes later.

You will see significant reductions in sub micron particle counts.

Most business do not have the fan going. System comes on and off depending on temperature. This box fan allows for continuous cleaning and showcasing the great air cleaning effects of the SFC air filter.

Great fit in poultry barns summer time in Canada and any other farming or other application.

2.5 Example Box Fan Test Results Here is an example of the results of a Box Fan in a room. At 12:20pm the box fan was placed in the room – look how hour after hour the Sub Micron Particles drop in the room. The test stopped at 5:20pm – 5 hours later with an 86% reduction in airborne particles.


2.6 Home Owner Air Quality Results These are the results in a home that has a golden retriever dog that sheds a lot of hair. When we first tested the home it measured over 1,000,000 particles. We then installed the filters and came back in two weeks to see the drop down to 278,000 particles. Look how week after week the particle count lowered.


2.7 Indoor Air Quality Testing Procedure The ability to filter sub-micron particles is only done by MERV 16 filters or HEPA filters. Both of these types of filters require the HVAC system to have new holding frames build and the air movement increased. These costly capital expenses have limited the ability to get clean air in our buildings. SFC filters make clean air a possibility for everyone.

Our testing methodology is very simple. We take air readings for a few days before putting on the filters. We then attach the filters to the return air vents and continue to take readings. Because air moves like water we take readings in numerous positions in the room. All of the sample readings are taken at chest height in the following locations: each corner, center of the room and in front of the Return air vents

Locations for Air particle readings

Symbol for the air return vent

Symbol for the door

Each of the air samples is taken approximately two feet from each corner. The site for the return is done directly in front of the return or inside the return duct. Use the 5 Point areas for testing the air quality of any room. Step 1: Get base particle count in the room you will be conducting the demonstration. Step 2: Place the filter on the intake vent. The duller, somewhat rough side of the filter should be placed facing the room and the shiny, smoother side placed touching the vent surface.


Step 3: Allow the demonstration box to run for two (2) minutes to clear the bad air. Step 4: Place the Dylos laser particle counter over the diffuser per the video and you can show the client how quickly the particle count drops. The demonstrator must keep the top of the Dylos unit touching the box for the best demonstration numbers. *The diffuser provides directed air which keeps unfiltered particles from entering the air stream and improves the Dylos count of filtered particles. Note: You may perform the same test with the filter they are currently using to show them the difference between filters. 2.8 Residential Installation Procedure Installation and testing in a home you have 2 ways of installing our product

1) Return Vents in Home Using about 15 – 20 square feet of product you can cut up and install inside all the return vents of the home.

a. You could charge $25 per square foot to $35 per square foot including installation or a bit lower for the DIY type of home owner.

i. With this method your opening order includes 2652 square feet of material and enough for 133 homes allowing you to make:

1. $66,300.00 by just selling at $25.00 per square foot. 2. $88,400 by selling 15 square feet / 177 homes.

The following images are how to install the air filters at a home using the vents.

1) Remove vent 2) Ensure vent is open 3) Place the vent on the filter

:


Example of dirt after 7 months

4) Cut filter around size of vent 5) Place cut filter over vent 6) Tape filter to all sides of vent

7) Re-install vent

Here is a filter removed after 7 months – notice the grey / brown colour all over the filter. (All vents in the house looked like this – the ones closest to the furnace were more dirty.)


2) Home Furnace Collect data. Collecting the home owner’s furnace is very important. When you are at the home be sure to collect the following data:

• Dylos Particle Tester – get readings in 5 areas of room (do test with box fan) • Make / Model / Serial Number of HVAC and contact the local dealer for more info • Existing Filter Size • Measure the extra clearance in the furnace to see if a BAG style filter will fit into

the clearance area. Typical Contractors should have these:

• CFM Meter • Static Pressure Meter • Amperage Meter

Take a reading on a sheet of paper and mark the date and readings. If you are doing the box fan test in a room record those. If you are doing an installation – keep the data from the first particle test for your client. Then you can go back with the Dylos particle tester and show them their indoor air quality improvements. You may want to go back once every 2 weeks for a month or so per client. AFTER Installation

Take the following measurements after the installation if you have installed at the furnace.

• CFM • Amperage

o You should see drop in amperage after the installation of our air filter.

2.9 Commercial / Industrial Installation Procedure

3) Collect data. Collecting the home owner’s furnace is very important. When you are at the home be sure to collect the following data:

• Dylos Particle Tester – get readings in 5 areas of room (do test with box fan) • Make / Model / Serial Number of HVAC and contact the local dealer for more info • Existing Filter Size

• Measure the extra clearance in the furnace to see if a BAG style filter will fit into

the clearance area.


Typical Contractors should have these: • CFM Meter • Static Pressure Meter • Amperage Meter

Once the data has been collected, you can discuss filter configuration with Sanders Filters Canada Inc. The numbers gathered provide the information necessary to determine what level of filtration you can provide in various sections of the facility. Return to the client with a detailed plan for installation and a cost proposal. You will be able to give them rough numbers before installation. The installation survey will allow you to refine the cost to the customer. Filters will need to be changed every 3-6 months, depending on air quality. The facility engineer will be able to assess restriction on the system with a magnehelic and can help determine when the filters need to be changed. TIPS:

Close the Door - Do not leave the room door open. You need a contained space for the test. Also be aware that the numbers of people in a room also have a huge impact on the level of particulate. In our testing at a local business, we noted jumps in particulate counts in their staff meeting room. With ten people sitting and talking in their conference room particulate jumped from 100,000 particles per cubic foot to 800,000 particles per cubic foot at .3 microns in less than an hour and a half. Hence the number of people in the room will also skew your testing.

1) Educate your client. Work with them so they too understand the ASHRAE

position paper. https://www.ashrae.org/about-ashrae/position-documents

Disease moving through the air is one thing, but the particulate also causes problems. Particulate is a huge driver in asthma and allergies. Global statistics vary, but asthma problems are everywhere. In Canada we have over 10% of our population afflicted with asthma. In the Middle East the numbers jump to 30%.

2) Get base line air quality readings using the methodology described above. Take the readings at the same time each day and in the same positions. Take the readings with the client so they too have the data from the laser particle counter. This will provide your base line air numbers.

3) Take readings daily for the next week. You will see a dramatic reduction in the particle count. This should be done so the customer also has access to the readings. Remember talking and people breathing will make the reading jump so you need to manage the test area.

https://www.ashrae.org/about-ashrae/position-documents


4) Comments: SFC provides remarkable reductions in airborne particulate. Because we use a Air Particulate Meter we have a good understanding on settling rates for large scale particulate and we understand that people have a huge impact on the air quality.

Skins cells falling off, breathing and speaking continue to add particulate to the air. Most never think of this and don’t fully understand it. What you will be doing is a controlled demonstration and your results will vary. In all cases the numbers will be very good. Sometimes you will see the filter perform better than the 90 percent efficiency rating and at other times it will be lower. In all cases it will be a dramatic improvement over what they have. That will be driven by things like doors being left open and people in the room. Air management is a dynamic process. Flushing a toilet, speaking and breathing can change the air quality.

Because we know some of the things that can affect air quality we can mitigate them by putting additional filters in rooms. The product can be installed in other devices to provide other means of air remediation.

Take a reading on a sheet of paper and mark the date and readings. If you are doing the box fan test in a room record those. If you are doing an installation – keep the data from the first particle test for your client. Then you can go back with the Dylos particle tester and show them their indoor air quality improvements. You may want to go back once every 2 weeks for a month or so per client. AFTER Installation

Take the following measurements after the installation if you have installed at the furnace.

• CFM • Amperage

o You should see drop in amperage after the installation of our air filter.

Understand your customer’s needs. Not all the air in the same facility will be the same quality. There likely will be areas that have considerable VOC concerns, which will require a gas-catching layer on the containment filter. There might have areas that are especially dusty, which might require a pre-filter on the containment filter. Remember, this unique filter media can be configured in numerous was to meet the specific needs and budget of your customer.


3.0 FAQ When going to larger businesses such as commercial and industrial buildings you should be on the lookout for Health & Safety contacts and speak to them about: Improving indoor air quality, increase worker productivity and reduce sick days.

3.1 Why was this new Filtration system Developed? Hospital-acquired infection (HAI) — also known as nosocomial infections are spread throughout facilities in part, by the mixing action of the HVAC system. This allows contaminated air in one room to be dispersed throughout all rooms served by the same air handler, in effect spreading pathogens from a single infected room to all rooms on the same system. Our Next-Generation Air Filter eliminates the problem of pathogens being spread by this mixing action of the HVAC system.

3.2 Why place the Filters in the Return Vent? The filter attached to the return vent prevents the pathogen from entering the HVAC system through the return vent. Preventing any possibility of it being spread to other rooms of the same HVAC system. The pathogen is thereby contained to only the original room where the release occurred. This process not only prevents the pathogen from entering the HVAC system. The Next-Generation Air Filter also captures and holds beyond HEPA efficiencies most of the pathogens, as they were about to enter the system, removing them from the air. Once the filters are installed, this process is automatic and continuous ever hour of ever day, straining the air and diluting the total quantity of pathogens in the air throughout the facility.

3.3 How do the filters placed inside the return vents, affect air flow? In the past, commercial building return vents have not been filtered and especially not at HEPA or near HEPA filtration. The Next-Generation Air Filters utilize a very specialized media specifically designed to provide very low static pressure, high flow, while maintaining HEPA or near HEPA efficiencies. Even with this low static pressure media, the concept of placing any filters inside the return vent seems foreign to the way we have done things in the past. It is logical that you would assume it could cause a problem with the air flow and thereby the necessary heating and cooling function of the HVAC system. These Filters allow full air to pass through them while on the Return vents causing no concern.


3.4 Could the Filters reduce air flow and cause problems? The Next-Generation Air Filters must be placed inside all return vents, when used. This provides for a uniform increase in static pressure throughout the entire system. Allowing the return vents to still be balanced. All commercial system are designed with and require Make Up Air Dampers to replace air that exits the building by the normal process as people enter and leave the building. This is normally 10% makeup air. This damper can be opened to allow more outside air to the system decreasing the vacuum or be closed to create more suction in the return side of the system. The additional resistance created after installing the filters on the return side will increase the face velocity of the air at the damper and should be inspected to verify the proper air flow at the damper, after installation of the filters is completed. This should be verified by the return side Magnahelic pressure reading. On large high pressure systems, It is strongly recommended that the make up damper be adjusted to “full open”, before installation and adjusted to the correct balance after the MCF Filters are installed to the correct balance. This adjustment should be done under the direction of your engineering staff or facilities manager and should easily correct any imbalance. 3.5 Can the air filter be used for Bio-terrorism Prevention? In the event of a Terrorist Attack, the terrorists goal will be to disperse the chemical agent or pathogen as quickly as possible throughout as much as the building, as fast as they can. After the release occurs, the terrorists will rely on the HVAC system assisting them in this dispersal. Any release of chemical agents or pathogens submicron in size will move with the air current throughout the common area or hallways where the release occurs. Many of these chemical agents or pathogens are submicron in size and would be picked up by the HVAC system that would act as a mixer, spreading the particles to other rooms and throughout the rest of the wing served by the same HVAC system. The Next-Generation Air Filters will all but stop this process by containing the pathogens to the release area only, providing time for personnel to exit other parts of the building. The Next-Generation Air Filters will also immediately begin diluting the release area of pathogens as they are drawn into the media over the return of the HVAC system, holding and removing them from the air. In this manner the HVAC system now helps to prevent the spread of pathogens instead of aiding in the dispersal. 3.6 What Efficiencies will these Filters Give? The media used in our Next-Generation Air Filters is rated at initial efficiencies to 99.97% @.1 micron We say ” to” 99.97% because the efficiencies can vary or be


reduced with higher air flow velocities in some return systems. Return HVAC systems can very in this face velocity from vent to vent and system to system within the same building. This is due to the design parameters of each individual system. If the face velocity goes beyond the rated flow, the media may drop below HEPA efficiency. Please keep in mind, HEPA filtration allows for only 3/10th, of 1% of the submicron particles to pass through the media. Even if, on your system the efficiencies of our Next-Generation Air Filters reduce to 99% or 98 % at 0.1 micron. This reduced efficiency would still be very effective at stopping, holding and trapping particle of this submicron size. Even this reduced efficiency would allow only 1-2% of the total particle through the media. The CDC currently recommends N-95 respirators that are rated 95% efficiency @.3 micron as sufficient protection for personal respirators for health care professionals treating H1N1 patients.
