Accessing clean, tasty water is essential for any home, but selecting the right water filtration system can be a challenge. Two popular options are countertop and under sink water filters, each offering unique advantages to homeowners who opt for them.
Countertop water filters are easily to install, budget friendly and portable, making them ideal for renters or those looking for a simple, yet effective solution. Alternatively, under sink filters offer superior filtration, a sleek design and better long term value.
This guide will explore both options, their advantages and drawbacks to ensure you are equipped with all the knowledge you need to make an informed decision for your family.
Understanding The Different Types of Water Filter
There are a range of different types of water filter systems available, each designed to remove contaminants at different levels from your home’s water supply.
- Countertop Water Filters: These systems attach to your faucet or come as standalone dispensers, filtering water before it reaches your glass. They are portable, affordable and require no plumbing modifications.
- Under Sink Water Filters: Installed beneath your sink of choice and connected to your water supply, these systems provide more advanced levels of filtration and keep the unit out of sight.
- Reverse Osmosis Systems: A highly effective filtration method removing approximately 98% of contaminants and impurities.
- Whole House Filters: Installed at the main water line, whole house water filtration systems filter all water in your house, ensuring every outlet in your home dispenses pleasant tasting, odour-free filtered water.
Understanding the different types of water filtration systems available allows you to evaluate the needs of your home and make an informed decision.
Countertop vs Under Sink Filters: Key Differences
When comparing countertop and under sink filtration options, several key factors should be evaluated, including ease of installation, effectiveness of filtration, aesthetics and cost. While both options have a positive impact on your water quality, they differ in convenience, space requirements and maintenance needs.
Installation & Set Up
Countertop water filters are a plug-and-play option, requiring no modifications to your home’s plumbing. Most models attach directly to your kitchen tap or use gravity-fed filtration, making them ideal for renters, or those living in temporary set ups.
On the other hand, under sink filters require installation beneath the sink, connecting directly to your home’s plumbing. While this involves some plumbing work, it results in a more permanent, cleaner solution. Many homeowners opt for professional installation to ensure a secure fit, particularly for reverse osmosis systems.
Filtration Effectiveness
Depending on the cartridge(s) used, countertop filters are effective at removing chlorine, sediments and some heavy metals, but under sink systems generally provide superior filtration. Many under sink models utilise multi-stage filtration, eliminating fluoride, pesticides, chlorine-resistant cysts and volatile organic compounds (VOCs).
Reverse osmosis under sink filters offer the highest levels of water purification, removing up to 98% of contaminants, including 100% of fluoride, making them the ideal solution for those with increased water quality concerns.
Space & Aesthetics Consideration
Countertop filters, as the name suggests, sit on your counter or attach directly to your tap, occupying visible space. While some models are more compact than others, they may clutter the area, making them less suitable for small kitchens or individuals aiming for a minimalist aesthetic.
Conversely, under sink filters are hidden within your cabinetry, providing a sleek, space-saving solution. These systems preserve valuable counter space, integrating seamlessly into modern kitchens, making them ideal for homeowners looking for a clean aesthetic.
Cost & Maintenance
Countertop filters are more affordable upfront, with lower initial costs and easy filter replacements. However, these systems generally require more frequent filter maintenance to keep them operating at an optimal level.
Under sink systems carry a higher investment upfront, but their longer-lasting filters and higher efficiency lead to improved savings over time. No matter which system you choose, the savings on purchasing bottled water are phenomenal.
Which Water Filter Is Best For You?
Choosing between a countertop and an under sink system will ultimately depend on your living situation, kitchen space, budget and water quality requirements. While both offer effective methods of filtration, each has unique benefits that suit different individuals in varying situations.
Best For Renters & Temporary Setups
For renters or those in temporary living arrangements, a countertop water filter is the best option. These systems require no permanent installation, are easy to move around with and attach directly to your tap of choice. This makes them ideal for holiday homes, apartments and rentals where modifying plumbing isn’t a readily available option. Under sink systems, however, are best suited to individuals who own their residence.
Best For Small Kitchens
If counter space is limited, an under sink filter is the superior choice. Unlike countertop models, which take up precious real estate near the sink, under sink systems are discreetly installed within the cabinet, preserving kitchen space. This makes them ideal for smaller kitchens, modern home designs or apartments, where maintaining clutter-free aesthetics and a functional kitchen space is a priority.
Best For High Filtration Needs
For households with unacceptable water quality, an under sink filter offers superior contamination removal. With multi-stage filtration, it removes heavy metals, chlorine-resistant cysts and VOCs, ensuring more pleasant drinking water. While countertop filters effectively reduce chlorine and sediments, they may not provide the same level of protection, making under sink systems a superior choice for comprehensive water filtration.
Best For Budget-Conscious Individuals
For a low cost entry into water filtration, a countertop filter is ideal. These systems carry low upfront costs, no installation and offer simple filter replacement. However, under sink filters provide better long term value with fewer filter replacements over time. For those prioritising long term savings, an under sink system may be a more suitable investment.
Addressing Common Questions About Countertop & Under Sink Filters
Selecting a water filtration system for your home raises several questions, particularly when deciding between countertop and under sink units. Below, we’ll explore some frequently asked questions to help clarify any concerns you may have.
Do Countertop & Under Sink Filters Remove The Same Contaminants?
No, multi-stage under sink filters provide higher filtration levels, particularly for fluoride, heavy metals and chlorine-resistant cysts. Countertop filters are effective for basic contaminant removal.
How Often Do Filters Need To Be Replaced?
Countertop filters generally require replacement every 3-6 months depending on the quality of the filter and the usage level. Under sink filters typically last 6-12 months before needing a change.
Can I Install An Under Sink Filter System Myself?
If you are confident working with basic plumbing fittings, most under sink filters can be installed without the assistance of a professional. Reverse osmosis systems, and individuals who want to guarantee a tight fit are better off working with an experienced installer to ensure effective installation.
Is There A Noticeable Difference In Taste?
Yes there is! Under sink filters, particularly multi-stage or reverse osmosis units, significantly improve the taste of your tap water by removing a wider range of contaminants when compared to countertop filters.

Final Verdict
Selecting between a countertop and under sink water filter depends on a few key factors including your household’s requirements, budget and available kitchen space.
A countertop system is affordable and easy to install, making it a great option for individuals who don’t own the property they are living in, or those looking for a temporary solution. However the unit takes up visible counter space and does not offer the advanced filtration of an under sink model.
An under sink water filtration system provides superior water quality, long term cost savings and space efficiency. While the initial financial outlay is higher, the improved filtration, aesthetics and less frequent filter replacements make them a better long term solution for homeowners.
