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.
  • Clean: remove contaminants through purification and filtration.
  • Ventilation: contaminants in the home can be reduced by adequate ventilation.
  • Monitoring and Maintenance: monitor and control humidity; change and clean filters regularily; have your ducts professionally cleaned on a regular basis.

The following chart gives an overview of our Lennox indoor air purifiers/cleaners. Click on the red text to get more information from the Lennox website. 

When selecting a furnace filter, filtration efficiency and air flow should both be considered. Some filters on the market can provide excellent filtration, but may harm your furnace motor if they are too restrictive to air flow.  Lennox designs filtration with the whole heating and cooling system in mind.

We also offer indoor air testing; test your home for levels of: particulate, odours/chemicals (VOC - volatile organic compounds), carbon monoxide, humidity, and temperature.

Definitions:

  • 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).
  • Particles/Particulate - pollen, tobacco 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).
