When you purchase a standard AC filter, you may note on the packaging that you are advised to change them out every one to two months. This is probably a good guidelines to adhere to if you consider yours a “normal” home with no variance on quality of life issues. These may include the following.

If you are single and keep a clean home, for example, you may check your filter after a month and discover it may hold out a while longer.
- Pets – Dogs or cats in the house? If so, you have pet dander. This could to put a bit of wear and tear on your AC filters. You may find with pets in the house you are changing the filters more often, perhaps every thirty days.

- Overall environment – Where do you live? Urban condos and apartments are likely to be more subject to pollution that gets sucked into the filters as opposed to rural living. Of course, a home in the country is not without the opportunity for dust, dander, and other allergens. Consider where you live and get a good gauge on checking every thirty to sixty days.
