Pure water machine and water purifier are two different types of water treatment equipment, and they have some differences in water quality purification. The following are their main differences:

Water purification degree:

Pure water machine: The main goal of a pure water machine is to produce highly pure water, commonly referred to as ultrapure water or deionized water. This type of water undergoes multiple processing steps, such as reverse osmosis, electrodeionization, etc., to remove almost all ions, microorganisms, and organic pollutants, producing high-purity water. It is suitable for high demand fields such as laboratories, medicine, and electronic manufacturing.

Water purifier: The goal of a water purifier is to improve the quality of tap water and make it more suitable for drinking and general household use. They usually use technologies such as filtration and activated carbon adsorption to remove most of the pollutants, but the water quality is not as pure as the water produced by pure water machines.

Application field:

Pure water machine: Pure water machines are mainly used in professional fields such as laboratories, medical facilities, electronic manufacturing, pharmaceuticals, etc. that require high water quality. Their water quality requirements are very strict to ensure the accuracy and reliability of the experimental and manufacturing processes.

Water purifier: Water purifiers are mainly used in homes, offices, commercial places, etc., to provide safe and delicious drinking water, as well as some daily water, such as cooking, washing, and showering.

Water quality standards:

Pure water machine: Pure water machines usually need to comply with higher water quality standards, such as foreign CLSI standards, ASTM standards, or pharmacopoeia standards, to ensure consistency and traceability of water quality.

Water purifier: Water purifiers usually only need to meet drinking water quality standards, which specify the safety and taste of general drinking water.
