Filtrete™ Filters Use Exclusive 3-in-1 Technology to Pull in and Trap Unwanted Particles, Allowing Cleaner Air to Flow Through.

It’s important to have a top-of-the-line air filter in your heating and cooling system to help maintain airflow and deliver cleaner air throughout your home.

Filtrete™ Filters with electrostatic charge have exclusive 3-in-1 technology that acts like a magnet to attract and capture microscopic allergens that can pass through fiberglass or non-electrostatic filters. Your air is cleaned each time it passes through the filter.

Plus, airflow through the filter remains strong and can last up to 3 months before often having a pressure drop below that of a brand new competitor filter.

Electrostatic filters are most effective when they are new and clean. Make sure you’re changing your filter at least every three months for maximum effectiveness.
