How to choose a water purifier in Shanghai (3 quick questions)

  1. Are you living in a rented apartment, or can you modify the plumbing?
  2. Do you mostly drink tap water directly, or boil it first?
  3. Do you need one tap in the kitchen, or whole-house filtration for showers and laundry?

FAQ

Do I need a whole-house filter or just an under-sink purifier?

For most rented apartments in Shanghai, an under-sink purifier is usually enough for drinking and cooking water. Whole-house filters are recommended if you own the property and want to improve water for showers, laundry and appliances as well.

What is the difference between RO and carbon filters?

RO (reverse osmosis) removes very small particles, salts and many dissolved substances, while carbon filters focus on improving taste and reducing chlorine and some chemicals. Many families use them together: RO for drinking water, and carbon filters for showers or whole-house systems.
