Chosing a water filter is really a tough call, because you have to know what kinda filter they does, some of water purifier can remove all necessary minerals thats is not a good thing, because when you drink anywhere else you became sick.
so I my advise dont drink purifier water, it will give you less imunity and you have to carry a water bottle with you always not purifier water.
only use water purifier to clean water, don’t use any advance which removes minrals, thats is not a good thing, keep in mind, don’t use any advance according to my opinion.
