To Microformulation’s point, city water typically includes Pseudomonas aeruginosa etc. at some level, typiucally in a biuofilm context. IF you use it, you should heat it 1st -prefer 80C but at least to minimal Pasteurizing levels - ~60C.

You should check Philippine regs.
60-95% is the typical range - but please be aware the aloe and guava may screw up your efficacy.

The guava article is a classic example of garbage science published in a 3rd rate journal.

Everthing was the statistically the same so they concluded an “implied”a benefit for guava.
The other links are to verbage.
