When it comes to air filters, size is an important factor to consider. The 16x25x1 size is often used instead of the 16x24x1 size because it's easier to remove. The actual size of the filter is the length, width, and thickness of the filter, which normally appears on the filter label just below the nominal size. If you buy a filter online, you can find the actual size in the product list or in the product description.
As an expert in air filters, I can tell you that using the wrong size won't necessarily damage your air conditioning system, at least not right away. However, it has an impact. Using the wrong size reduces the efficiency of your heating and cooling system. This can add up quickly and become a more apparent problem that you're likely to notice on your next utility bill.
For this reason, I recommend using the 16x25x1 size instead of the 16x24x1 size for ease of removal. The actual size of the filter is important to consider when purchasing a filter, as using the wrong size can reduce efficiency and increase your utility bill. It's important to check the product list or description when buying online to ensure you get the right size. When shopping for air filters, make sure you know what size you need and double-check that it matches what's listed on the product page. If you're unsure about what size you need, consult with an expert or contact your local HVAC technician for help. By following these tips, you can ensure that you get the right air filter for your home and avoid any potential problems with your heating and cooling system.
