There are three options for safe drinking water.
What are the pros and cons of each option?

• 

  Option (1) Buy water from a store

  Advantage You can buy as much natural water as you like from among the many kinds available on the market.

  Disadvantage It is troublesome to buy and transport large quantities of water for drinking, cooking, and brushing teeth. If you use it for cooking, the cost is rather high.

• 

  Option (2) Purchase water from a home delivery system

  Advantage Since it is a home delivery system, you don't have to buy water from a store every time you need it.

  Disadvantage Getting the water each time you use it for cooking or brushing your teeth is troublesome.
  It is difficult to load the water into the server.
  It is unhygienic because a water pump needs to be inserted into the tank.
  Since chlorine has been removed from the water, large bottles must be used quickly.
  Sometimes the water is not delivered on the specified date or time, leaving you short of water.

• 

  Option (3) Install a water purifier to make drinking water at home

  Advantage This is very easy because there is no need to shop for water or move heavy bottles.
  The same water that is sold at convenience stores comes out of the faucet, so it is very convenient for cooking, brushing teeth, washing your face, etc.

  Disadvantage As there are various models, it is difficult to know which one is best for you.
  You may feel worried that you really can make clean and delicious water at home.

• Reverse Osmosis is a water purification process that extracts only water molecules from tap water to produce pure water, removing all impurities to 95-98% or more.
• Reverse Osmosis is the first water purification technology to remove even radioactive substances due to its micron-dependent microstructure.
  Other commercial water purifiers often advertise that they ensure that good substances (minerals etc.) remain in the water, meaning that they do not remove the harmful minerals (potassium, mercury, etc.) found in old water pipes, pesticides, or agricultural water.

Polka Dots is able to purchase, sell and rent various types of water purifiers. However, considering how much water is consumed each day, and that it is given to babies and children, we do not wish to provide water for which the removal of harmful substances cannot be confirmed.

We use reverse osmosis membrane water purifiers, recognized all over the world as the highest-level technology, and also use U.S. Du Pont and Japanese Toray brand reverse osmosis membranes. Even if this raises the cost, this is natural when considering the mission of Polka Dots to ensure the safety and security of our customers.
