How to Change Your Air Filter if You Have Allergies

If you or someone in your family suffers from allergies, it is essential to replace the air conditioner filter regularly. Generally, it is recommended to change the filter every 20 to 45 days, or more often if necessary. For 1 to 3 basic air filters, brands suggest changing them every 30 to 90 days. If someone in your family has mild to moderate allergies, you can opt for a better air filter or change it more frequently.

Homeowners with someone living in their home who has allergies should replace their air filter about once every six weeks. You may even consider changing it more often if the person with allergies has difficulty breathing in your home. People with allergies are more sensitive to indoor air quality, so an air conditioning filter should be used to reduce the amount of allergens in the indoor air supply. For those who suffer from allergies, AC filter replacement should be done every 6 weeks for the cleanest possible air. Air filters and oven filters should be checked at least once a month. If they are dirty, they should be replaced with a clean air filter.

To check if the filter is dirty or clogged, remove it from the air handler and hold it close to a light source; if you can't see the light through the filter, it's time to change it. More expensive pleated air filters can be changed up to every six months. These general guidelines do not take into account filter sizes or types, such as thicker filters or smaller filters. Therefore, it is recommended that you never leave an air filter unreplaced for more than 90 days. If you suffer from allergies or asthma, you should change filters frequently.

Respiratory problems make you much more sensitive to airborne particles, so you should change your air filter every six weeks for optimal indoor air quality.

But changing the air filter once every three months should work well for the average suburban home owner. Air filters help remove dust, pollen, pet hair, and other small particles from the air so you don't breathe them in. This type of filter would be beneficial in areas close to high-traffic areas such as highways and busy intersections. If you have a suburban home and don't have pets or people living under your roof with allergies, don't hesitate to change your air filter once every three months.

Your air filter will turn dusty and gray over time; if you hold it close to a light source and can't see the light through the filter, it's definitely time to change it. For those living in more urban areas, they should change their air filters more often than those in the suburbs. As a general rule of thumb, pleated air filters and heating filters should be replaced every 90 days. With older homes or in areas with lots of surrounding foliage and high pollen counts, you may need to change your air filter more often. And if you purchase an older system, plan to replace the filter more often for optimal quality.

Newer options are available that allow you to reuse a filter by washing it clean of any dust and dirt they may have trapped. If you're looking for an eco-friendly option that will save costs in the long run, then finding a replaceable filter may be the solution for you. It's a good idea for homeowners with children to change their air filters at least once every two months and possibly sooner if children have allergies or if there are pets in the house. Studies have shown that indoor air can be two to five times more polluted than outdoor air; even if you regularly clean pet hair from your furniture or have a pet that doesn't shed much hair, they can still tax your HVAC system and air filter.
