How Often Should You Inspect Your 14x30x1 Air Filter?

The general consensus is that you should replace your home air filter every 3 months or 90 days. But what happens if you let that time go by for a bit? Before we talk about WHEN you should change your air filter, let's start with WHY. The only way to be sure how often the air filter should be changed is to have a visual inspection of the filter every month. After a few months, you'll get an idea of how quickly it gets dirty.

You'll need to reevaluate if you have a new pet or if the outdoor air quality has been poor. Filters should be changed every 30 to 90 days, depending on the type and efficiency of the filter. However, according to Energy Star, filters must be changed every month during peak summer and winter hours, when the air conditioning system is operating at its maximum capacity. As air passes through a building's air conditioning system, air filters trap and collect large and small particles, such as dust, allergens, and microorganisms.

When it comes time to buy new air filters for your HVAC system, there are a few things to consider. Pleated air filters are more expensive at first, but they are also more efficient at trapping particles and can last up to 90 days, depending on use. The only type of filters that trap allergens and spores are HEPA filters, or high-energy particulate air filters. It will no longer be able to filter the air properly, allowing dust and contaminants to enter the HVAC system.

These air filters act as barriers to prevent contaminants from entering the HVAC system or from circulating through the air. It's important to note that there are high-efficiency filters that are designed to filter out small particles of bacteria, mold and mildew, but standard MERV 8-11 filters only block larger particles of dust, dirt and hair. As a general rule, lower home occupancy extends the life of the air filter, while higher home occupancy reduces it. We also offer 5 inch oven filters (16x25x5 or 20x25x), whole house air filter brands, and rigid cell furnace filters.

Air filters must be changed periodically in your home to keep the system running smoothly and to maintain optimal air quality. You'll find it easier to remember this important task if you first learn how often to change your air filter. When it comes to maintaining a healthy central air system in their home, most homeowners know that they must change their air conditioning filters regularly. Your specific situation is unique, but most air filtration experts agree that heating filters have an overall lifespan.
