Hello. How often will it need to be replaced: every year, every few years?

Hi Terence P., Normally you need remove the hair and clean the blue core regularly (like two weeks or one month, it depends on usage). For the replacement, we believe that 1 year is better, but maxmium less than 2 years, even it is on good condition. Excessive bacteria are difficult to remove.
