If you have pets, children, or allergy sufferers in your home or business, it is important to maintain superior indoor air quality. To do this, you should replace your air filters more often. K&N washable household air filters are designed to fit directly into the heating and air conditioning filter slot, just like a typical disposable air filter. With multiple dimensions and sizes available, installation is easy.
Using a washable and reusable air filter can help you save money compared to disposable filters that must be repurchased frequently. In an average suburban home, disposable filters should be replaced every 90 days. If you have pets, they should be replaced every 60 days or sooner. When creating a filter with this tool, it is important to use the “actual” filter size as shown by the tape measure, not a nominal filter size.
