  4. 4. MicroShield Environmental Services, LLC. 5 OF 85 WHAT IS22
  5. 5. MicroShield Environmental Services, LLC. 6 OF 85 • IAQ: Indoor Air Quality refers to the quality of the air in the indoor environment. This may also be referred to as Indoor Environmental Quality (IEQ).
  6. 6. MicroShield Environmental Services, LLC. 7 OF 85 • Good IAQ is the quality of air which has no unwanted gasses or particles in it at concentrations which will adversely affect someone. • Poor IAQ occurs when gases or particles are present at an excessive concentration so as to affect the satisfaction or health of occupants.
  7. 7. MicroShield Environmental Services, LLC. 8 OF 85 Acceptable indoor air is defined by ASHRAE: • “AIR IN WHICH THERE ARE NO KNOWN CONTAMINATES AT HARMFUL CONCENTRATIONS AND WHICH A SUBSTANTIAL MAJORITY (USUALLY 80%) OF THE PEOPLE EXPOSED DO NOT EXPRESS DISSATISFACTION” -ASHRAE 62-1999
  8. 8. MicroShield Environmental Services, LLC. 9 OF 86
  9. 9. MicroShield Environmental Services, LLC. 10 OF 85 • Types Of Indoor Air Pollutants • The Centers for Disease Control and Prevention (CDC) places air pollutants into three general categories: • 1. Particulates 2. Bioaerosols 3. Volatile Organic Compounds
  10. 10. MicroShield Environmental Services, LLC. 11 OF 85 • Particulates • Common indoor air particulates include dirt, dust, fibers, tobacco smoke particles and fireplace or wood stove soot. Airborne particles can range from 0.1 microns in size to 100 microns in size;
  11. 11. MicroShield Environmental Services, LLC. 12 OF 85 • Bioaerosols • Bioaerosols are microorganisms or particles, gases, vapors, or fragments of biological origin (i.e., alive or released from a living organism) that are in the air. Bioaerosols are everywhere in the environment.
  12. 12. MicroShield Environmental Services, LLC. 13 OF 85 • Volatile Organic Compounds (VOC) • are a carbon-based chemicals that easily evaporate at room temperature. • Some VOC's have odors other VOC's have none. • Odor does not indicate the level of risk. • There are thousands of different VOC's produced and used in our daily lives.
  13. 13. MicroShield Environmental Services, LLC. 14 OF 85 PARTICULATES33
  14. 14. MicroShield Environmental Services, LLC. 15 OF 85 • PARTICULATE: a state of matter in which solid or liquid substances exist in the form of aggregated molecules or particles. Airborne particulate matter is typically in the size range of 0.01 to 100 micrometers (µm).
  15. 15. MicroShield Environmental Services, LLC. 16 OF 85 • TOTAL SUSPENDED PARTICULATE: the mass of particulates suspended in a unit of volume of air when collected by a high volume sampler. • TSP refers to all particles in the atmosphere. TSP was the first indicator used to represent suspended particles in the ambient air.
  16. 16. MicroShield Environmental Services, LLC. 17 OF 85 • PARTICULATE MATTER: a suspension of fine solid or liquid particles in air, such as dust, fog, fume, mist, smoke, or sprays. Particulate matter suspended in air is commonly known as an aerosol.
  17. 17. MicroShield Environmental Services, LLC. 18 OF 85 • RESPIRABLE PARTICLES: particles that penetrate into and are deposited in the non-ciliated portion of the lung. Particles greater than 10 micrometers aerodynamic diameter are not respirable. Peak deposition of respirable particles occurs within the size range of 0.2 to 5 micrometers (µm).
  18. 18. MicroShield Environmental Services, LLC. 19 OF 85 • MICROGRAM (µg): one microgram is equal to one thousandth (1/1,000) of a milligram or one millionth (1/1,000,000) of a gram • MICROMETER (µm): one micrometer is equal to one thousandth (1/1,000) of a millimeter or one millionth (1/1,000,000) of a meter
  19. 19. MicroShield Environmental Services, LLC. 20 OF 86
  20. 20. MicroShield Environmental Services, LLC. 21 OF 85 • Fungal spores • Pollen • Tobacco smoke • Combustible appliances • Asbestos fibers Contaminates Come From Inside and Outside • Bacteria • Viruses • Insect feces • Insect body parts • Cat and dog dander

  22. 22. MicroShield Environmental Services, LLC. 23 OF 86
  23. 23. MicroShield Environmental Services, LLC. 24 OF 85 Particulate Matter - Air Quality Index (AQI) and Health Concerns   • An AQI of 100 for PM2.5 corresponds to a PM2.5  level of 40 micrograms per cubic meter (averaged  over 24 hours).  • An AQI of 100 for PM10 corresponds to a PM10  level of 150 micrograms per cubic meter (averaged  over 24 hours).    
  24. 24. MicroShield Environmental Services, LLC. 25 OF 86
  25. 25. MicroShield Environmental Services, LLC. 26 OF 85 • Particulate matter may be generated by natural  processes, pollen, bacteria, viruses, mold, yeast,  soil from erosion) or through human activities.   • The smaller and lighter a particle is, the longer it  stay’s in the air. Particles greater than 10  micrometers in diameter tend to settle to the ground  in a matter of hours whereas the smallest particles  less than 1 micrometer can stay in the air for weeks 
  26. 26. MicroShield Environmental Services, LLC. 27 OF 86 2.5
  27. 27. MicroShield Environmental Services, LLC. 28 OF 85 • The effects of inhaling particulate’s have been  widely studied and include asthma, lung cancer,  cardiovascular issues, and premature death.  • The size of the particle is a main determinant of  where in the respiratory tract the particle will come  to rest when inhaled. Fine Particles can penetrate  the deepest part of the lungs.
  28. 28. MicroShield Environmental Services, LLC. 29 OF 85 Fraction Size range PM10 (thoracic fraction)  <=10 μm PM2.5 (respirable fraction)        <=2.5 μm PM1       <=1 μm Ultrafine (UFP or UP)        <=0.1 μm PM10-PM2.5 (coarse fraction)  2.5 μm - 10 μm

  34. 34. MicroShield Environmental Services, LLC. 35 OF 85 • The same measures of humidity control to prevent  mold growth are needed to discourage the dust  mite population that exists in all living areas.  • Choosing and maintaining the proper humidity  level to avoid indoor mold will also work to  minimize the level of dust mites and dust mite  allergens

  36. 36. MicroShield Environmental Services, LLC. 37 OF 85 IAQ Illnesses55
  37. 37. MicroShield Environmental Services, LLC. 38 OF 85 • MCS: Multiple Chemical Sensitivity is an  unexplained condition where a person reports  sensitivities and adverse reactions to low levels of  chemicals. 
  38. 38. MicroShield Environmental Services, LLC. 39 OF 85 • BRI: Building-Related Illness: This term is used  when symptoms of a disease from several  occupants of a building can be directly linked to  specific airborne contaminants in that building.   This differs from SBS because with SBS no  specific illness or cause can be identified. 
  39. 39. MicroShield Environmental Services, LLC. 40 OF 85 • SICK BUILDING: a building whose occupants  complain of health and comfort problems that can  be related to working or being in a building 
  40. 40. MicroShield Environmental Services, LLC. 41 OF 85 • HUMIDIFIER FEVER: ("Ventilation Fever") a  respiratory illness caused by exposure to toxins  from microorganisms found in wet or moist areas  in humidifiers and air-conditioners. 
  41. 41. MicroShield Environmental Services, LLC. 42 OF 85 • HYPERSENSITIVITY PNEUMONITIS: a group of  respiratory diseases, including humidifier fever that  involves inflammation of the lungs.  Most forms of  hypersensitivity pneumonitis are caused by the  inhalation of organic dusts, including molds. 
  42. 42. MicroShield Environmental Services, LLC. 43 OF 85 FILTRATION66
  43. 43. MicroShield Environmental Services, LLC. 44 OF 85 • There are many filters available on the market  today.  • The most common are the one inch filters found in  supermarkets, hardware stores and home supply  retailers. All these filters guarantee a percentage of  effectiveness, but that can be misleading. 
  44. 44. MicroShield Environmental Services, LLC. 45 OF 85 • Each time the HVAC fan cycles air into the home, armies of potentially harmful spores, along with other allergens and pollutants, can be propelled through the supply ducts and spewed throughout your home into the air your family breathes.
  45. 45. MicroShield Environmental Services, LLC. 46 OF 85 Type 1 Type 1 Type 2 Type 3
  46. 46. MicroShield Environmental Services, LLC. 47 OF 85 1. Standard throwaway filters: Designed to protect the air handler only. No capability of collecting fine particles. 2. These filters are designed to protect the air handler and do a fair to poor job at that. 3. Most are made of fiberglass and provide no protection against fine or ultra-fine particles.
  47. 47. MicroShield Environmental Services, LLC. 48 OF 85 2. Washable Filters: These filters are very restrictive to airflow and are difficult to clean thoroughly, especially if they have a poly, sponge-like, inner filter.
  48. 48. MicroShield Environmental Services, LLC. 49 OF 85 • Electronic Air Cleaners: These air cleaners are 95% efficient at .3 microns when new or clean. They can reduce in efficiency very quickly as they load and are difficult to clean thoroughly and maintain. • Many home owners do not take the time to clean these on a regular basis, thus the product rarely works at the efficiency that it was designed for.
  49. 49. MicroShield Environmental Services, LLC. 50 OF 85 • Large 4 to 5 Inch Media Filters: These filters have a large amount of filter surface to allow for good air flow. They do a good job at protecting the air handler and keeping it clean. • They can collect a large amount of dust and particles above one micron in size, but have no capability of collecting particles and allergens that measure below one micron.
  50. 50. MicroShield Environmental Services, LLC. 51 OF 85 Pleated Size MERV 8 - 11
  51. 51. MicroShield Environmental Services, LLC. 52 OF 85 • What Is MERV? • The MERV (Minimum Efficiency Reporting Value) rating of a filter describes the size of the holes in the filter that allow air to pass through. The higher the MERV rating, the smaller the holes in the filter, the higher the efficiency.
  52. 52. MicroShield Environmental Services, LLC. 53 OF 85 • MERV is an industry standard rating, so it can be used to compare filters made by different companies. • Residential filters commonly have MERV ratings of 1-11. The higher the MERV rating, the more efficient the filter is, and the more particles it can filter.
  53. 53. MicroShield Environmental Services, LLC. 54 OF 85 • A MERV rating of 6 means the filter is 35% to 50% minimum efficient at capturing particles, sized 3.0-10.0 microns. • A MERV rating of 7 means the filter is 50% to 70% minimum efficient at capturing particles, sized 3.0-10.0 microns. • A MERV rating of 8 means the filter is 70% minimum efficient at capturing particles, sized 3.0-10.0 microns. • A MERV rating of 11 means the filter is 85% minimum efficient at capturing particles, sized 3.0-10.0 microns.
  54. 54. MicroShield Environmental Services, LLC. 55 OF 86
  55. 55. MicroShield Environmental Services, LLC. 56 OF 85 • Another consideration is that a dirty filter impedes the flow of air. This is called "pressure drop". It is a double-edged sword - the more effective a filter is at grabbing the smaller particles, the sooner it will clog up with these particles and cause pressure drop.
  56. 56. MicroShield Environmental Services, LLC. 57 OF 85 • A Healthy HVAC System Means Cleaner Indoor Air • It’s estimated that more than 70% of all indoor air quality problems involve the HVAC systems. Dirt, dust and other particulates can accumulate on system components and in ductwork.
  57. 57. MicroShield Environmental Services, LLC. 58 OF 85 • “Bacteria, molds, pollen and viruses can breed in stagnant water that has gradually accumulated in ducts, humidifiers and drain pans.” • –Article appearing in Health Facilities Management, June 1997
  58. 58. MicroShield Environmental Services, LLC. 59 OF 85 • Stand-alone room air cleaners cannot possibly match the effectiveness and efficiency of whole house systems. • They simply do not move the large volume of air required to remove indoor air pollution. By using your existing forced-air system, you can have measurably cleaner indoor air.
  59. 59. MicroShield Environmental Services, LLC. 60 OF 85 HOUSE KEEPING77
  60. 60. MicroShield Environmental Services, LLC. 61 OF 85 1970 1980 Barrel HEPA
  61. 61. MicroShield Environmental Services, LLC. 62 OF 85 • Few people think about their vacuum cleaners as sources of air pollution in their homes. How could something that makes the carpet look clean be polluting the air? • Yet frequently the air people breathe after vacuuming is dirtier than it was before they vacuumed!
  62. 62. MicroShield Environmental Services, LLC. 63 OF 85 • Many vacuum cleaners pick up the larger particles of dirt so that the carpet looks clean. • But the smaller particles - are not retained by the vacuum cleaner's filter. • Instead, they are shot out in the exhaust air, aggravating allergies and redistributing dust, mold spores, lead dust, animal dander, etc., throughout the home.
  63. 63. MicroShield Environmental Services, LLC. 64 OF 85 • These tiny particulates that are recycled float around for hours before settling down. Anyone in the room is breathing them in. • Many carpets contain years of accumulated recycled particulates. Carpets may contain dust, mold spores, pollen, animal dander, dust mites, pesticides, lead dust, asbestos and fiberglass fibers, and other pollutants.
  64. 64. MicroShield Environmental Services, LLC. 65 OF 85 • Many vacuum cleaners that sound as if they have HEPA filters really don't. • Read the ads closely. You will see words such as "HEPA-like" or "removes 99.97% of particles 5 micrometers in size." • 5 micrometers is about 17 times as large as 0.3 micrometers.
  65. 65. MicroShield Environmental Services, LLC. 66 OF 85 • In addition to having a good filter, it is important for an allergy vacuum cleaner to have a sealed unit. It does little good for particulates to be stopped by a HEPA filter, only to be exhausted through openings in the vacuum housing. • HEPA-filtered vacuum cleaners are not necessarily designed to be leak-proof.
  66. 66. MicroShield Environmental Services, LLC. 67 OF 86
  67. 67. MicroShield Environmental Services, LLC. 68 OF 85 • Dusting is just not fun.
