How to Choose an Air Purifier

Breathe easier with an air purifier. Did you know that the average Canadian spends about 90% of their time indoors and that levels of air pollution inside your home can be two to five times higher than outdoor levels? Some common household allergens are: mould spores, tobacco smoke, dust, dust mites, animal dander, and pollen from ragweed, grass and trees. Minimize the health risks associated with poor indoor air quality by using an industry certified air purifier.

Planning Considerations

Consider the following when selecting your air purifier.

  1. What are your needs? Do you need to reduce allergy or asthma symptoms, lessen dust, remove odours, or sanitize an area of the home?
  2. Which rooms do you spend the most time in? Determine the size of those rooms you need covered.
  3. Choose the technology whose features match your needs. There are three main types from which to choose: portable true HEPA, portable HEPA-type and whole-house UV air treatment.
  4. Look for the AHAM industry seal to ensure your unit is certified. All AHAM certified units will bear a clean air delivery rate (CADR). This rating signifies the amount of filtered air being output. The higher the CADR number, the more powerful the unit.
