Our 15x25x1 air filters are easy to install and work in various settings. If one uses a 15x25x1 air filter in a high-intensity industrial environment, the filter should be changed every 30 days. This number increases to around 90 if it’s being used in a less intense setting, like a household. By using a media, our 15x25x1 air filters stop harmful particles, like dust and pet dander, from getting into the air. Some of our 15x25x1 filters are ecologically friendly because they’re made from recyclable materials.
