A water purifier has become a necessity in every household. However, one issue that many users complain of is the lack of proper space to install it in the kitchen. An under-the-sink water purifier can come to the rescue in such scenarios.
An under-counter or under sink water purifier is similar to a regular RO water purifier. The only difference is rather than wall mounting, you can install it under the sink counter.
They are designed specifically so that you can install them with built-in sinks that you will mostly find in modern kitchens. Before buying an under-the-sink water purifier, consider the following factors.
Purification Technology:
Along with sediment and carbon filters, all the under the sink water purifiers use only RO, UV, or both RO+UV/UF technology to purify water.
If the water supply at your home is hard with higher TDS levels, you should go ahead with an RO purifier. If the water is hard and if it also contains disease-carrying bacteria and germs, you should buy a purifier with RO+UV technology.
Storage Capacity:
The minimum storage capacity of a water purifier should be 5-7 liters. This will make sure that drinking water is available all the time.
Size/Compact Design:
It becomes an important factor if there is a storage issue in your kitchen. Hence, buy a compact model that can be easily installed under the sink without consuming too much space.
Water pressure and cartridge life are some other factors that also play an equal role in deciding the quality of the under-sink water purifier. You can check our buying guide to learn more about them.
