3M™ Filtrete™ Replacement Filters for your Room Air Purifier

 Filtrete replacement filters

Filtrete room air purifiers use a patented technology that enables more air to pass through the filter*, which in turn means more air can be purified.

Filtrete Replacement Filters

All Filtrete replacement filters feature:

  • Patented air filtration technology


An electrostatically charged filter is specially designed for capturing large, common airborne allergens like pollen, mould spores and dust mite debris from air passing through the filter. The fibres within the filter are charged to act like tiny magnets that attract and capture small particles. The unit also captures dust, bacteria, smoke, smog and particles that can carry viruses from air passing though the filter.

Filtrete room air purifiers use replaceable filters t to deliver the enhanced filtration of an electrostatic filter on a sustained basis. 3M recommends a filter change every 3 months of continuous use, replacing the filter is important for maintaining the effectiveness of your Filtrere Room Air Purifier.
