This filter is compatible with the Blue Pure 121 air purifier.
This filter features highly-porous, activated carbon pellets for extra protection against harmful gaseous pollutants like odors, smog, exhaust, volatile organic compounds (VOC), smoke odors, and chemicals. The Combination Particle + Carbon filter uses an activated carbon mesh sheet, designed to remove light household odors and chemicals.
A red filter replacement indicator appears on the air purifier when it is time to change filter, after about 6 months of operation.
After you replace your filter, press the center button down to reset the filter light indicator until the red light disappears. It usually takes 7-10 seconds and may take up to 30 seconds depending on the model.
