Manufacturers have designed air filters in HVAC systems to remove microscopic particles, including pet dander, bacteria, dust, pollen, smoke and mold spores from the air in your living space. So, it’s important to replace them after every month or on a bi-monthly basis to keep your space clean and healthy.
