Size of the System

The size of the system is closely related to the amount of water a system can filter in a day. Having known the amount of water you need to filter each day, now consider the amount of space that is available for the storage of the filter, whether it is over-counter or under-counter.

Are you buying the system to be placed on the counter or under the sink of your kitchen? How big is your kitchen? Will the reverse osmosis system fit in your kitchen without making it feel crowded and cluttered? These are some of the questions that you need to ask yourself before making the purchase.

Take measurements of the available space before going out to buy a system so that you can know the amount of space you are working with.

A reverse osmosis system is an investment. If you are going to invest in one, you want to make sure it lasts longer. The process of buying one and having it installed is not easy, therefore, you do not want to go through the process yearly or after a short period of time.
