To help you make the most informed decision, ask yourself some questions as you shop around. What type of pollutants are prevalent in your area? Do you or any household members suffer from allergies or respiratory issues? How often do you want to change or clean your filter? By answering these questions and doing some research, you can select the best central air filter to improve your home's indoor air quality.
