How to Clean Dirty Air Filter

Taking Care of Your HVAC System

If you or someone in your family suffers from allergies, you already know how important it is to check the air filter in your home. Even if there are no allergy sufferers in your house, you should replace the air filter once a month. The Heating, Ventilation, and Air Conditioning (HVAC) system is your home’s breathing system. Your air filter traps the dust, pet dander, pollen, dust mites, and other particles that float in the air. Many of us don’t pay attention to this home maintenance detail as we often as we should. The air filter can be neglected for weeks, resulting in serious health problems and negative consequence on our utility bills.

Your House Needs to Breathe

If too many bacteria make a home in your lungs, you won’t be able to breathe properly until the doctor gives you medicine to clear them. The air filter acts like lungs for your HVAC system by allowing clean air to flow freely. Its job is to make sure that dirty air particles stay trapped in the filter rather than floating around in the air making people sick and preventing the HVAC system from working properly.

A dirty air filter means you and your family are breathing stale, dirty air—air that could contain dangerous pathogens that cause disease. In fact, indoor air pollution, like outdoor pollution, is one of the top environmental health risks for children, for those who are sick, and for the elderly. You and your family deserve to breathe clean, healthy, unpolluted air at home.

If you recently moved to a new home or apartment, check the air filter. The previous homeowner or landlord at the apartment complex may have completely forgotten to replace it.

Higher Utility Bills

If you don’t like getting high air conditioning or heating bills, replace your air filter. A dirty filter can’t trap any more dirt. As a result, your HVAC system will use more energy to keep you cool in the summer and warm in the winter.

Higher Repair Costs

Many of the more serious HVAC repair and replacement costs are directly associated with not replacing air filters on a regular basis. An air filter that is so dirty that it is no longer functioning can seriously damage your HVAC system. Damage to your HVAC system is a totally avoidable problem! By checking your air filter on a regular schedule, you ensure that your HVAC system will work effectively for many years to come, saving you thousands of dollars. When it comes to protecting your HVAC system, prevention is the best defense.

When to Check Your Filter

Depending on your HVAC system, you should change your air filter every 1 to 3 months; a replacement every 30 days is the most common practice. You should never allow more than 90 days to pass without replacing an air filter. Use your phone or a calendar to make sure you don’t forget. There are many different types of filters you can buy. Each filter offers different features and benefits, but every filter must be checked and replaced at regularly.
