Are you wondering what size air filter you need for your home or office? It's a common question, and the answer isn't always straightforward. The standard size of an air filter is usually printed in bold and large text on the filter frame, and it is usually rounded to the nearest whole number compared to the actual size. For example, 16 x 25 x 4 inches is a standard size, and this is the one you should focus on instead of the actual size. If the filter is too large, it will wrinkle the frame, restrict airflow, and reduce its longevity.
Most online air filter retailers have a custom air filter page where you can find a selection of custom sizes. If you are unsure of how often you should change your air filter, there are several warning signs to look out for. If the air filter has dust or is not working properly, it is time to replace it. To determine what air filter sizes you need, you should look at the standard size of your home's return vents. These vents are responsible for controlling the movement of air to and from the HVAC unit.
Interestingly, 70% of what Filterbuy sells does not fall into the 10 most common air filter sizes. These filters help improve air quality in your home or office and ensure that your HVAC system works efficiently. Air handlers are usually installed near the HVAC system, and in some homes, they are installed in ductwork. If the dimensions on the air filter frame are too faded to read or there is no air filter visible, you can measure it yourself. Before you can answer the question: “What size air filter do I need?” it is essential to have the right dimensions.
Please note that the sizes of air conditioner and oven filters must be smaller than the measurements of the filter compartment. A higher MERV rating indicates that the filter is better at maintaining air quality and removing environmental contaminants. MERV stands for Minimum Efficiency Reporting Value and is used to measure how well an air filter can remove particles from 0.3 to 10 microns in size from the air. When selecting an air filter, it's important to consider both its size and MERV rating. The right combination will ensure that your HVAC system runs efficiently while also providing clean air for your home or office. If you're still unsure about what size air filter you need, contact an expert who can help you find the right one for your needs.
