How often should I change or wash my filters?
That depends on the size of the filter(s), the size of the heating and air system, and the type of filter used. The typical one inch disposable filter should usually be replaced every 1-3 months of use. Thin washable types are also 1-3 months in between washings. The more expensive pleated filters like the 3M Filtrete type will need to be replaced more often than lesser quality filters because they catch more dirt. They also restrict the airflow which can actually increase the system operating costs. We have large professionally installed box filters which are replaced usually 1-2 years and do a far superior job of removing dirt and dust without restricting the systems airflow.
