FAQ
What Blueair models are compatible with this filter?

This filter is compatible with the following Classic 301 model.

Are Blueair filters HEPA?

No, Blueair filters are less dense than traditional HEPA filters, allowing our air purifiers to be quieter and more energy-efficient. Instead of HEPA filters, we use a combination of electrostatic and mechanical filtration that we call HEPASilent™ technology to achieve the same level of filtration efficiency as 'True HEPA' - with less energy and noise.
