So guys, I'm currently living in a condominium now as tenant. I've got a question about the Diamond Water Purifier.
There are 3 "purifying bottles" that I've seen on the sink which are A, B, C. I seen the A and C "purifying bottle" has never been change while B has been change as the latest date is 2017, while A and C is 2013.
Is it safe to change just the "purifying bottle" B? I'm aware that the house owner is a bit stingy though.
The main reason why I ask is due to the fact that I always get cracked lips when I come back to KL from Sarawak. I'm aware about the El-Nino that's currently happening in peninsular but I've been drinking the water the I boiled for safety lately(it's been 3 days) and my lips aren't cracking anymore.
Is it possible the water hasn't been purified properly due to the reason the "purifying bottle" not being changed? Or it's just that all of the "purifying bottles" has been changed but the covers has not?
