No, it is not safe to drink boiled water from a pressure cooker. While boiling water in a pressure cooker can kill most bacteria and pathogens, it does not make the water safe for consumption if the pressure cooker is not designed for this purpose.
Pressure cookers are primarily used for cooking food and not for boiling water intended for drinking. They are not designed or equipped with the necessary components, such as filters or purification systems, to ensure the water is safe to drink.
Drinking water should be free from harmful contaminants and microorganisms. If you want to purify water for drinking purposes, consider using appropriate methods like boiling water in a clean pot or using a water purification system designed for this specific purpose. Boiling water in a regular pot for at least one minute (or three minutes at higher altitudes) is generally sufficient to kill most pathogens and make it safe for consumption. Alternatively, using a water purifier or boiling it in a pot with a lid can be safer options. Always prioritize safety and cleanliness when it comes to drinking water.
