The 20x25x4 air filter is a larger oven than other oven filters, with a thickness of four inches. This offers a greater surface area to capture more particles and germs from the airflow, making it more effective and durable than other cheaper disposable air filters. When it comes to air filters, size matters. The difference between a 20x20x4 air filter and a 20x25x4 air filter is the thickness of the filter.
The 20x25x4 air filter is thicker than other air filters, with a thickness of four inches. This offers a larger surface area to capture more particles and germs from the airflow, making it more effective and durable than other disposable air filters. Worse, incorrectly sized air filters can place excessive stress on the air conditioning system, damage it, and increase energy bills. When you hear the term “standard air filter size”, you might think that if your air filter is standard, it will be easy to find it when you get to the store.
However, this is not the case: there are standard 20-inch sizes for air filters and none of them have the same measurements. The actual size of the filter in length, width, and thickness may be smaller than the nominal size indicated on the label. To get the correct dimensions, you can measure the filter or look for the actual size on the outside of the filter. The MERV (minimum efficiency report value) is a rating that indicates how well an air filter can collect particulates from your home air. The thickness of the air filter ranges from 1 to 5 inches deep; some options are more common than others and the oven can determine the thickness you can use.
Generally, HVAC technicians recommend changing 1-inch air filters every 30 days, while 4-inch filters can be changed every 3 to 6 months. The 4-inch thick 20x25x4 air filter has an advantage over the 1-inch filter in terms of longevity, airflow, and maximum filtering potential. It works better and lasts longer than other cheaper disposable air filters. Learn the difference between a 20x20x4 and 20x25x4 air filter in terms of thickness, longevity, airflow, and maximum filtering potential for great filters at a great price.
