  3. 3. IAQ AND VENTILATION <ul><li>Ventilation </li></ul><ul><li>  </li></ul><ul><ul><li>ASHRAE Standard 62 </li></ul></ul><ul><ul><li>Basically contaminant dilution </li></ul></ul><ul><ul><li>Even diluted, some contaminants are still problems </li></ul></ul><ul><ul><li>Has an energy penalty </li></ul></ul><ul><ul><li>Air usually must be cleaned </li></ul></ul>
  4. 4. IAQ AND SOURCES <ul><li>Source Control </li></ul><ul><li>  </li></ul><ul><li>Source elimination, attenuation or substitution </li></ul><ul><li>Requires knowledge of source </li></ul><ul><li>Usually complicated/impossible </li></ul><ul><li>Usually involves change for occupants > > >difficult </li></ul>
  5. 5. IAQ AND FILTRATION <ul><li>Filtration </li></ul><ul><li>  </li></ul><ul><li>Will Always Be </li></ul><ul><li>Needed For Contaminants </li></ul><ul><ul><li>Originating in the Building </li></ul></ul><ul><ul><li>Originating Outside of and entering the building </li></ul></ul>
  6. 6. IAQ AND FILTRATION <ul><li>Filtration </li></ul><ul><li>  </li></ul><ul><li>Will Always Be </li></ul><ul><li>One of the most energy efficient options for improving IAQ </li></ul><ul><li>One of the most doable options for improving IAQ </li></ul><ul><li>One of the lowest capital cost options for improving IAQ </li></ul>

  13. 13. DUST VS. CONTAMINANT <ul><li>DUST </li></ul><ul><li>Filter selection: </li></ul><ul><ul><li>what is cheapest </li></ul></ul><ul><ul><li>arrestance </li></ul></ul><ul><ul><li>bypass and leakage less important </li></ul></ul><ul><li>CONTAMINANT </li></ul><ul><li>Filter selection: </li></ul><ul><ul><li>what is to be controlled </li></ul></ul><ul><ul><li>MERV </li></ul></ul><ul><ul><li>bypass and leakage more important </li></ul></ul>
  14. 14. BUT <ul><li>Nowadays </li></ul><ul><li>BOTH </li></ul><ul><li>are important considerations, depending on the conditions </li></ul><ul><li>AND </li></ul><ul><li>they are not mutually exclusive—control for contaminants, </li></ul><ul><li>control for dust </li></ul>
  15. 15. IAQ and Effective Filtration Systems <ul><li>Filtration system selection— </li></ul><ul><li>the contaminant control model </li></ul><ul><li>Determine what is to be controlled </li></ul><ul><li>Determine the level of control </li></ul><ul><li>Select the best filtration system </li></ul>

  22. 22. FILTRATION SYSTEM SELECTION <ul><li>Determine the level of control needed </li></ul><ul><li>Sampling might help determine approximate contaminant concentrations </li></ul><ul><li>Most times, experienced WAG is going to be good enough, but seek help when needed </li></ul><ul><li>Customer’s needs should have major impact on level of control needed </li></ul>
  23. 23. FILTRATION SYSTEM SELECTION <ul><li>Select the best filtration system </li></ul><ul><li>Best system provides control of important contaminants to the desired concentrations </li></ul><ul><li>Focus on the customer’s needs—not the products available for sale </li></ul>
  24. 24. FILTRATION SYSTEM SELECTION <ul><li>Select the best filtration system </li></ul><ul><li>MERV 10 minimum—based on mold (about 3.0-10.0  m particle size range)—but, system should have most efficient filtration in particle size ranges of contaminant of interest </li></ul><ul><li>Filters should not exceed allowable fan pressure drop when loaded to factory specification </li></ul>
  25. 25. FILTRATION SYSTEM SELECTION <ul><li>Select the best filtration system </li></ul><ul><li>Filters should not load up too rapidly </li></ul><ul><li>System should have minimal bypass and leakage </li></ul><ul><li>Gaskets should be reliable, effective, durable and easy to replace </li></ul>
