How much water should I use for my Philips Avent sterilizer?

• Are you using a 2-in-1 Electric steam sterilizer? Fill the water reservoir with exactly 3 oz. of tap water
• Are you using a 3-in-1 Electric steam sterilizer? Fill the water reservoir with exactly 3.5 oz. of tap water
• Are you using a 4-in-1 Electric steam sterilizer? Fill the water reservoir with exactly 3.5 oz. of tap water

Note: Do not use more water than recommended to avoid the water reservoir from overflowing during use. If you use less water than recommended, the steaming cycle will finish too early.
