Breathe Easier with the Filtrete 300 MPR Dust Reduction Filter

The Filtrete 300 MPR dust reduction filter is the perfect solution for improving the air quality in your home. Not only does it help keep your air conditioning and heating systems running efficiently, but it also captures dust, pollen, and other large particulate contaminants in the air. This high-performance filter outperforms comparable one-inch washable and reusable non-electrostatic fiberglass filters. The electrostatic filter attracts and captures dust, pollen, and other large particulate contaminants in the air to keep your home surfaces clean and dust-free for longer.

With each passage through the specially pleated filter, the air in your living space improves, creating a healthier home environment. This dust reduction filter also keeps your heating and air conditioning equipment running efficiently by removing dirt and reducing stress on the motor. It is recommended to change the filter every three months, but this may vary depending on individual conditions in your home. For nearly 25 years, Filtrete filters have been delivering cleaner air to millions of homes, becoming leaders in residential air filtration.

Developed by 3M engineers to help capture airborne allergens, Filtrete media is electrostatically charged to act as small magnets that attract and capture microscopic particles from the air as it passes through the filter. Installation is simplified by the inclusion of easy-to-understand arrows in the frame that help identify the direction of the airflow and, subsequently, the way the filter should be positioned. We recommend replacing the filter every 90 days to keep the system running efficiently and the air clean. However, this is subject to change depending on the filter size, as well as other varying factors for pet owners, allergy sufferers, homes with children, etc.

We now offer more than 600 different sizes of custom air filters to ensure that everyone can find a solution that fits their needs. At Filterbuy, we care about providing value to you with a quality product that ships directly to your door. The 3M dust reduction filter has a microparticle performance rating (MPR) of 300 and is ideal for capturing large particles from the air, including household dust and pollen. With indoor air surprisingly two to five times more polluted than outdoor air, this filter can make a difference in maintaining a healthier home environment by cleaning the air with every pass through the filter.
