There are also circumstances when it’s a good idea to change the filter even more frequently, as often as once a month. If you have a large family or the home has many occupants, dust and dirt will accumulate more often, also if you have pets in the house you should consider changing the filter every month. If any family members suffer from allergies or if there are smokers in the house, this is another reason to change it more regularly.
