The Role of Air Filters

The EPA says we spend 90% of our time indoors. And indoor air is 2 to 5 times more polluted than outside air.

Air filters help protect your health and your HVAC. Knowing how filters work helps you make smarter choices for your home.

1. Improves indoor air: Air filters trap the pollutants in your place. Without them these harmful particles would be roaming around your place.

2. Protects the HVAC: The air filter also protects the HVAC itself. It stops the dust and debris from getting inside the unit.

3. Reduces costs: With a good high quality filter like Filterbuy 16x36x2, you’ll spend less money on repairs and maintenance.
