The only way to be sure how often your air filter should be changed is to visually inspect it every month. After a few months, you'll get an idea of how quickly it gets dirty and need to re-evaluate if you have a new pet or if the outdoor air quality has been poor. For basic air filters from 1 to 3, brands usually recommend that you change them every 30 to 90 days. If someone in your family has mild to moderate allergies, you can use a better air filter or change it more often.
The general recommendation is that oven filters be changed at least once every 90 days. It's important to remember that the only way to know if you really need to change the filter is to check it once a month. If you or a family member has a history of allergies or asthma, plan to change your filter once a month, following recommendations from medical associations, including the American Academy of Allergy, Asthma, and Immunology. When air filters don't change, dust, pollen, dirt, and other contaminants accumulate and decrease filter efficiency.
For every dog that loses hair, expect to replace the filter a month earlier than you would in a pet-free home. When you buy a new air filter, you'll find the manufacturer's recommendations for the replacement program. You may not have realized that the boiler filter needs to be changed because not all air conditioning systems need heating, ventilation and air conditioning filters.

However, if you use your air conditioning system almost constantly or live in a big city with poor air quality, you'll have to change the filter more often. It is generally recommended that residential air filters be changed every 30 days if regular fiberglass filters are used.

This will result in inadequate filtration and the entry of pollutants into your home air. Even if you live in a temperate climate with excellent air quality, there's another important reason to change your boiler filter as recommended.

It's important for homeowners to understand how often they should replace their 20x20x1 air filters in order to maintain good indoor air quality and prevent costly repairs down the line.
