A Guide to Purchasing Under Sink Water Purifier Systems

Our bodies consist of 70% water, making it the most crucial element to man. The safety and cleanliness of the water we consume is a concern. Bacteria come in many sizes, and the smaller ones make it past community filters and into our homes via the water supply.

Worry not because installing a simple water purifier can address these concerns. Whether you’re concerned about cleanliness or focused on adding more minerals to your drinking water, water purifiers can help you. However, the many options in the market tend to confuse buyers. Read on to understand the benefits of installing water purifiers and how to choose the right one.

What do Water Purifiers do?

Water purifiers filter out toxic materials like heavy metals and bacteria. They use two methods of filtration, making them more effective. By physical filtration, dirt and particles cannot move past a filter. Additionally, through chemical filtration, the water filter removes microscopic contaminants.

Moreover, these filters also add additional minerals to the water. Installing a water filter can give you healthier and tastier water.

Types of Water Purifiers


Mechanical water filtration systems focus on sediment contaminants and follow basic physical filtering properties. The filter size withholds larger particles, not allowing them to pass.

Absorption Filters

Absorption filters work on chemical attraction properties and are usually carbon filters. These filters filter out microscopic and chemical contaminants, providing better filtration.

Typical filters use Granular Activated Carbon or GAC that also removes tastes and odours from the absorbed contaminants.

Ion Exchange Filters

These filters are relatively more expensive and advanced. Ion exchange softens hard water, and these filters come especially handy for water at high temperatures. At higher temperatures (autoclaving, commercial coffee machines), the water evaporation leaves salt deposits that can clog. However, ion exchange filtered water is free of salts and more suitable.

Reverse Osmosis (RO) Filters

These filters are the most popular filtering systems in the market. They purify water by forcing water through a semipermeable membrane, removing almost all contaminants, making water clean and healthy.

While these systems are relatively more expensive, they come with multi-stage filtration and promise almost 99.8% pure water.

Combination Systems

These systems typically use an RO filter in conjunction with other filtering systems. This multi-step process makes water healthier and safer.

How do Under Sink Water Purifiers work?

Upon installing this water purifier under the sink, a valve diverts water from the main pipe to this filter for filtration. An exit valve from the filter extends to above the sink. This exit valve serves as a source for filtered and clean water.

Benefits of Installing an Under-Sink Water Purifier

Cleaner and Healthier Water

Millions of people worldwide suffer from diseases like typhoid due to the consumption of impure water. Even though tap water is safe to drink, families should go the extra mile to remove all contaminants. In addition, some filtration systems even add essential minerals that filtering may have removed.

Better Tasting Water

While it may seem absurd, water does have a taste that it attributes to its contaminants. Some of these contaminants even give water a foul smell and taste. Filtration systems remove these contaminants and any accompanying odour and taste.

Easy Installation and no Additional Space

Installing an under-sink water purifying system does not use additional open space. Additionally, installing a system is relatively simple and does not require any plumbing skills or knowledge.


Apart from being easy to maintain and preventing a score of diseases, this investment helps you save on bottled water.

When getting a filter for coffee machine usage, the filter helps you use your other device well, helping you save on repair costs.
