Maintenance procedures vary depending on the negative ion generator.
Some products require you to clean the ionizing needles or replace the filters on a regular basis,
while those which generate negative ions by crashing water require you to clean/refill the water tanks.
You should know what maintenance work is required to maintain the performance
before you purchase the negative ion generator.
