Do You Really Need an Air Filter? A Comprehensive Guide

Do you need an air filter to improve your health and relieve allergies and respiratory symptoms? The answer is not straightforward, as it depends on your home and the type of air purifier you choose. Air purifiers are useful for removing the smallest particles that can slip through a filter, and if combined with the right set of filters, they can remove more than 98% of contaminants. Generally, it is recommended to replace pleated air filters every 90 days, but this may vary depending on the type of filter. Air filters are important for keeping your home clean and healthy, and if you have allergies, they may help.

However, it is best to consult a professional to make sure you have the right type of air purifier and filter for your home. At its most basic function, an air filter removes impurities such as dust, pet dander, or even bacteria from the air that flows through the system. Not only does this improve the air quality inside your home, but it also protects your HVAC system from potential damage. Most air purifiers have notifications that tell you when the time is right to replace the filter.

For some filters, such as HEPA filters, it is recommended to replace them once a year. The Minimum Efficiency Report Value (MERV) rating for an air filter measures how effectively the filter prevents dust and other contaminants from passing through the filter into the air stream. It is important to leave the selection of these filters to the professionals, as filters that are too powerful will cut off airflow through the HVAC system, leading to component damage and a loss of home comfort. If replacing the air filter simply isn't possible for an extended period, going beyond 90 days won't cause irreparable damage to your air conditioning system. If you're considering adding an air filter to your home, it's best to consult a professional who can help you determine what type of filter is best for your needs.
