Studies have shown that indoor air pollution caused by a dirty air filter can trigger allergic reactions and sinus congestion in people who are sensitive to animals, pollen, and mold. An air filter can collect and house these allergens and allow them to circulate around homes when the air conditioner is in use, especially when the air conditioner filters are dirty. The air in your home is contaminated with dust, pollen, dander, mold spores, and other particles, which can be the cause of up to 60% of asthma cases. A good quality air conditioning filter can help reduce these air pollutants. However, a dirty air conditioning filter has the opposite effect.
Air conditioners filter out harmful particles from the air before blowing it around the house, but when the air conditioner filter fills up, its efficiency decreases. As a result, air pollutants and asthma triggers are pushed with cold air from the air conditioner throughout the house, causing asthma attacks. You're probably already familiar with outdoor air pollution, such as smog, and how it can have a serious effect on your health. But did you know that dirty indoor air can make allergy and asthma symptoms even worse? When your HVAC system and filter work harder to keep the air clean due to smog and other pollutants entering your home, it's time to change the filter more often - for example, once a month. Air filters that look dirty should be replaced as soon as possible, even if they say they last longer than a month. During a study conducted in Chandigarh, dust samples were collected from air conditioning filters from hospitals, guesthouses, offices, schools and homes.
These results are serious warning signs that may indicate that you have problems with your home's indoor air quality. When it comes to a healthy home environment, indoor air should be clean and free of allergens and other pollutants. When that airflow is hampered by a dirty or clogged air filter, it means that your system has to work a lot harder to cool your home. If you have allergies or asthma, it's worth taking the time and a small additional cost to upgrade your HVAC filter to a HEPA filter. This will help trap all dust and other particles, preventing them from entering the air and spreading.
An overloaded air blower can fail completely if not taken care of properly, causing the entire system to fail and costing you thousands of dollars for repair or replacement. These arrows indicate in which direction to install the air cleaner to match the direction of the air flow. By using high-quality filters and changing them regularly, you can reduce symptoms and live healthier.
