Details about why you need to replace your filter and how often.
Nearly every activity inside and outside your home contributes to indoor air quality and how often you need to replace your filter. Here is a list of factors that will contribute
The type of filter medium and MERV rating - air filters come in many shapes and sizes, which greatly affects how often a filter needs to be replaced. Find out more in Central Air Systems & Filters
How often your central system is on - if you live in a temperate zone, your central system may only be active in the winter. If air isn't moving through your ducts, it's not being cleaned by the filter.
The indoor sources of air pollution - activities like renovations, cooking, and cleaning can produce harmful pollutants that need to be removed from the air through a filtration system
The outdoor sources of pollutants - living near a major roadway, or in an area with large amounts of construction work will produce a lot of pollution that can seep into the home, even if the windows are closed.
The number of pets and how much they shed - most types of pets produce dander (skin flakes) and can carry mites. In addition, indoor/outdoor pets will bring in pollen, mold, dirt, and allergens from outside.
The number of people in the home and the types of activities of the occupants. New research shows that the human body produces a lot of particles and chemicals that can contribute to poor air quality.
According to Energy Star, you should:
Check your filter every month, especially during heavy use months (winter and summer). If the filter looks dirty after a month, change it. At a minimum, change the filter every 3 months. A dirty filter will slow down airflow and make the system work harder to keep you warm or cool — wasting energy.
Many sources also suggest that you should increase your filter replacement frequency if anyone in your home is sensitive to air pollution. According to the World Health Organization, air pollution is a known carcinogen. We take thousands of breaths per day and spend over 90% of our time indoors, so it's important that we take measures to protect our health and wellness.
