HVAC Air Filter Replacement

Air filters trap dust, pollen, and pet dander. Replacing them on time maintains air quality and HVAC efficiency.

Adjusted Replacement Interval

Adjusted Life = Rated Life x (1 - Pet Factor - Allergy Factor)

Each pet reduces filter life by about 15%, and allergy concerns warrant replacing 20% sooner. A clogged filter reduces airflow, increases energy costs by 5-15%, and can damage the HVAC system.

Esempio Risolto

A 90-day rated filter in a home with 1 pet and no allergies, costing $15 each.

  1. Adjusted life = 90 x (1 - 0.15 - 0) = 90 x 0.85 = 76.5 days
  2. Rounded = 77 days
  3. Filters per year = ceil(365 / 76.5) = 5 filters
  4. Annual cost = 5 x $15 = $75
