You will find this checklist useful no matter which water method you use.
1. You must know your home water source first, whether it is tap water, borewell water, or something else.
2. You must replace RO filters on time. Do not blindly trust an unmaintained RO machine.
3. You must research the company if you buy can water. Do not choose based only on low price or taste.
4. You must inspect the can. Check if it is clean, undamaged, and properly sealed.
5. You must clean your dispenser regularly. Even good water can cause problems if your home equipment is dirty.
6. You cannot judge water safety just by its taste or smell. The CDC notes that you cannot evaluate water safety based purely on taste, smell, or appearance.
The real question is not just RO vs Can water. You need to ask where it came from, how they purified it, how they maintained it, and how they stored it. The answers to these four questions will help you understand the quality of your daily drinking water.
