Health problems can arise if an air filter isn't working properly, allowing dust and allergens to circulate throughout the home. This can cause allergies and respiratory diseases. An HVAC system has to work hard to extract air through a clogged filter, so it's important to change your air filter every 90 days or 3 months. This may vary depending on the location of your home, if you have pets, and the age of your system and equipment.
If you have pets in your home, you should consider changing the filter every 60 days or 2 months, and for households with multiple pets or people with allergies or respiratory conditions, we recommend changing the filter every 20 to 45 days. Vacation homes or vacant homes that don't have much use can expect to change filters every 9-12 months. The more you use your home, the more you need to change the air filter. No other factor affects the performance and efficiency of your air conditioning system as much as a dirty or clogged filter.
When the air filter is clogged with dust, dirt, and grime, the boiler and air conditioner have to work twice as hard to move air around your home. This will increase your energy bills, increase your carbon footprint, and drain your budget. Fiberglass filters have a lower price; however, they will need to be replaced more frequently (usually every 30 days). With regular maintenance and replacement of air filters, you can avoid unnecessary damage to your unit.
The strongest filters are reusable, usually with metal frames, and can be cleaned according to the manufacturer's instructions. Inhaling polluted air can have a detrimental impact on health, causing allergies and making asthma and other respiratory problems much worse. Make sure you don't buy a filter that has a rating higher than 10, as it can severely restrict the airflow of your system. The Minimum Efficiency Report Value (MERV) rating for an air filter measures how effectively the filter prevents dust and other contaminants from passing through the filter into the air stream.
Some manufacturers recommend replacing air filters every 30 to 60 or 90 days, depending on the type of air filter. During allergy season, air filters can work overtime to remove allergens, dust, and other debris circulating through the heating and cooling system. This is especially true if homeowners begin to notice particles floating in the air and subsequently cause allergic reactions. Regularly changing your home's air filter is essential for maintaining a healthy environment in your home.
It helps reduce health risks associated with breathing in polluted air, as well as preventing damage to your HVAC system caused by clogged filters. Make sure you check your manufacturer's instructions for how often you should replace your air filter.
