I'm currently looking for under sink filter too and comparing between Aquaphor and 3M. Here are my queries and would really appreciate if anyone can help as I couldn't get those information that i needed from the internet. Queries :-

i. Are the Aquaphor Crystal Solo and 3M AP Easy Complete sufficient to make the tap water drinkable? FYI, I'm currently staying in a condo which is about 8 yo which i believe they have a centralised water filter.

ii. 3M Ap Easy Complete is about RM960~ as per Lazada but what is the price for Aquaphor Crystal Solo?

iii. 3M Ap Easy Complete cartridge is about RM270 as per Lazada too, how about the cartridge price for Aquaphor Crystal Solo?

iv. Let's say a small family now about 3 pax, as per recommendation for Aquaphor Crystal Solo, the cartridge should be changed every 12 month; how about 3M Ap Easy Complete cartridge?

Would really appreciate if anyone can help

Thanks!
