Factors to Consider when Buying an RO Water Cooler

The capacity of the Water Cooler

The amount of water you need depends on the number of people using the unit in a day. How many are you in your household? If you want one for the office, what’s the size of your team? If you have a big family or organization, go for a unit with a high purification and storage capacity for an endless water supply.

Temperature Settings

Before placing an order for the water dispenser, check whether it comes with the temperature requirements that you prefer.

Are you after a dispenser that will help you prepare coffee? If so, it should have the hot water temperature settings. It should also have room temperature and icy cold water settings.

Check the water cooler model depending on your temperature preferences. Also, ensure that the unit has the option of changing the temperature settings with different weather conditions.

Cleaning and Maintenance

Water coolers require regular cleaning hence the need to get a model that you can clean with ease. If possible, get one that comes with a self-cleaning feature.

It should also be easy to maintain and with filters that you can replace with ease when the need arises.


Although most water coolers operate silently, certain models make a lot of noise when running. You don’t want to end up with a unit that wakes up your fuzzy model every time someone dispenses water, right?

Go through online reviews to ascertain whether the model is a quiet one or not.


Water coolers provide cold, hot or room temperature water immediately. With one, bottled water becomes a thing of the past. It saves you a lot of time and effort since you won’t have to heat your water manually.
