Both the original (purchased prior to 2017) and the current Breathe Safe air purifiers require very little maintenance, but still need to be cleaned from time to time. Depending on the levels of dust or other particulates in your environment, it may need to be cleaned as often as every week, but at least once a month.
With consistent daily use, dust and other particulates in the air can collect on the inner plates and needles of the Breathe Safe device. Excessive amounts of dust and particulates reduce the ion and oxygen production of the machine. The more dust that accumulates underneath the discharge plate, the more the output production decreases.
Dust particles on the plate and needles must be cleaned regularly to maintain ion output, and the effectiveness of the machine. The device can prematurely fail if it is never cleaned, which voids the warranty.
To clear dust and particulates from the Breathe Safe, simply unplug the unit, flip it over 90 degrees, and use a moist cotton swab or children's toothbrush to gently wipe the underside of the plate and in between the needles.
You do not need to remove the top cover to clean the Breathe Safe, but doing so allows more light and increased particle visibility during cleaning. You may remove it, if you choose, as shown in the pictures, but be careful not to break off the four pins that hold on the top cover.
