With increasing concerns about water pollution and contaminants, it's crucial to invest in a reliable water purifier. But with so many options available, it can be challenging to decide which one is perfect for your needs. 

One common dilemma people face is choosing between a wall-mounted water purifier and an under-sink water purifier. The wall-mounted water purifier is something you've probably seen in many homes. It's like a comfy, old pair of sneakers – easy to reach and install.

On the other hand, there's the under-sink water purifier. It's like those sleek, stylish shoes that you keep hidden in your closet. It promises advanced water cleaning but hides beneath your kitchen sink, saving space and keeping things looking tidy.

In this guide, we'll break down the pros and cons of each type to help you make an informed decision.

Wall-Mounted Water Purifier

Wall-mounted water purifiers are perhaps the most common and readily available type. These purifiers are typically installed on the kitchen wall or any suitable space. Let's explore its advantages and disadvantages.


  • Wall-mounted purifiers are a breeze to install. You don't need to make significant changes to your kitchen's plumbing or invest in professional installation services. Most models come with a user-friendly manual for DIY installation.

  • These purifiers are designed to save precious counter space. In smaller kitchens, where every inch matters, wall-mounted purifiers can be a lifesaver.

  • They offer the convenience of a simple tap to dispense purified water. You don't need to open cupboards or fuss with additional taps, making it an excellent choice for households with children or elderly family members.

  • In general, wall-mounted purifiers tend to be more affordable than under-sink models. If you're on a budget, this could be a crucial factor in your decision-making process.


  • Wall-mounted purifiers usually have smaller filter cartridges, which means they might require more frequent replacements compared to under-sink models. This can be a minor inconvenience and a slight increase in long-term costs.

  • Some homeowners prefer a clean and minimalist kitchen look, and having a purifier on the wall might not fit their aesthetic. It's a matter of personal preference, but it's essential to consider.

Under-Sink Water Purifier

As the name implies, under-sink water purifiers are fitted underneath your kitchen sink. They have a special set of advantages and disadvantages.


  • Under-sink purifiers often come with larger and more advanced filter systems. They can effectively remove a wide range of contaminants, including heavy metals, chemicals, and microorganisms, providing cleaner and safer drinking water.

  • If you prefer a clutter-free kitchen, under-sink purifiers are the way to go. They are concealed, making your kitchen look neat and tidy.

  • These purifiers typically have longer filter lifespans, which can save you money on replacement filters in the long run.

  • Under-sink purifiers can deliver a higher flow rate of purified water, making them suitable for larger households with higher water consumption.


  • Unlike wall-mounted purifiers, under-sink models often require professional installation, which can be an added cost.

  • While they don't occupy counter space, under-sink purifiers use up some cabinet space, which may limit storage or organization options under the sink.

  • They are usually more expensive than wall-mounted purifiers due to their advanced filtration systems and installation requirements.

So, Which is the Perfect Water Purifier?

The choice between a wall-mounted and under-sink water purifier ultimately depends on your specific needs and preferences. We offer you advice on both types on the basis of some factors that should be taken into account while making a decision:

Budget: If you're on a tight budget, a wall-mounted water purifier might be the better choice. However, keep in mind the long-term filter replacement costs.

Space: Look up to your kitchen layout. If you have limited counter space, a wall-mounted purifier can help save room for other appliances and activities. If you prioritize a clean, clutter-free look, an under-sink model is more suitable.

Water Quality: If your water source has a high level of contaminants, an under-sink purifier with extensive filtration capabilities may be the better choice for ensuring the safety of your drinking water.

Household Size: If you have a larger family or high water consumption, an under-sink purifier with a higher flow rate might be more practical.

Aesthetic Preferences: Your personal taste matters. Do you want the purifier to be visible on your wall, or would you prefer it to be hidden under the sink?

Maintenance: Consider how often you're willing to replace filters and whether you want a purifier with a longer filter lifespan.


There is no one-size-fits-all answer to whether a wall-mounted or under-sink water purifier is perfect. It's about finding the right balance between your specific requirements and preferences.
