Indoor Air Quality solutions:

• Elimination (Source Control): identify and remove or reduce the sources of poor indoor air quality in the home. Pollutants that can affect indoor air quality include: chemicals (VOC - volatile organic compounds off-gassing from building materials and furniture), dirt, dust, dust mite allergens, odours, mildew, mould spores, bacteria, viruses, and too low or too high humidity.
• Ventilation: contaminants in the home can be reduced by adequate ventilation.
• Clean: remove contaminants through purification and filtration.
• Monitoring and Maintenance: monitor and control humidity; change and clean filters regularily; have your ducts professionally cleaned on a regular basis.

• Bioaerosols - mildew, bacteria, mold spores, dust mites, fungi, pet dander, viruses.
• HVAC - Heating, Ventilation, Air Conditioning.
• MERV - (Minimum Efficiency Rating Value) describes the filter's ability to capture particles. The higher the MERV rating, the higher the percent of particles captured combined with how small the particles are, which means enhanced filtration. A typical fiberglass filter = MERV 1. Currently, MERV 16 is the highest filtration for box filters (near HEPA efficiencies). Click here to read more on MERV ratings.
• Particles/Particulate - pollen, tabacco smoke, allergens, dust, ash, dirt particles, insulation, asbestos (particles smaller than 2.5 microns pass through the lungs and into the bloodstream, increasing the likelihood of illness).
