Product Information

Compatible with Blueair Classic 405 air purifier.

Particle filters minimise allergy triggers, viruses, and bacteria for a healthier environment with high filtration efficiency. Together with HEPASilent™ filtration technology, Blueair particle filters remove 99.97% of airborne particles down to 0.1 microns, including pollutants such as pollen, dust, pet dander, mould spores, viruses, bacteria, fine smoke particles and more.

Unlike generic look-a-likes, genuine Blueair replacement filters are specifically designed to maintain superior performance over time and ensures your warranty remains intact.

When it’s time to replace your filter (about every six months), start by unplugging your air purifier. Open the back door to remove the old filter and vacuum away any dust on the inside. Insert the replacement filter, close the back door, and plug back in. It really is that easy.
