What type of filters are used in the Blue air purifier?

The Blue air purifiers use one main filter and one pre-filter:

Main filter

• The standard main filter is a Particle filter with a Carbon mesh for particle removal and gas reduction.
• SmokeBlock filters can be used as replacement filters in Blue air purifiers, instead of the standard Particle + Carbon filters. The SmokeBlock filters offer extra protection against wildfire smoke particulates and emissions (toxic gasses, smog and odors), in addition to protection against airborne particles (dust, smoke, pollen).

Pre-filter

• The pre-filter is a fabric personalizable pre-filter that can be vacuumed and washed in the washing machine regularly (washing instructions can be found on the label of the pre-filter). The pre-filter catches large particles and protects the main filter inside the air purifier.
