MERV 8 filters offer basic protection against dust and pollen, making them suitable for many residential HVAC systems. However, they may not adequately filter out smaller particles like bacteria and smoke. For those with allergies, asthma, or other respiratory conditions, a higher MERV rating might be necessary. It's essential to balance air quality needs with your system's compatibility. Always check your HVAC system's manual to ensure you choose the appropriate filter.**
