Best Countertop Water Filters

Regardless of the source, water contains some level of contamination whether it’s chemical disinfectants added to it, or naturally occurring ingredients like sediments or minerals. Ideally, most tap waters should undergo some level of filtration before consumption.

With few exceptions – e.g. gravity water filters – countertop water filters are pressure-based filtration units designed for a quick and easy filtration. Their filtration efficiency ranges from simple taste and odour removal filters to filters that can tackle even more serious contamination issues like bacteria and heavy metals.

The best countertop water filters are easy to install and maintain, and deliver great-tasting contaminant-free tap water every time you turn on the tap.

Reasons to Install a Countertop Water Filter

Countertop water filters are especially suitable for small apartments or rentals, and they are the filter of choice for people who move a lot, or who want to avoid installing a plumbed-in water filter system.

Beyond these aspects, countertop water filters are a worthwhile investment, and here are a few reasons why:

Easy to install – countertop water filters are installed by simply attaching the filter tube to your kitchen faucet. This process takes only a few minutes of your time, and you can do it yourself without the help of a plumber.

Targeted Filtration – countertop filters allow you to customize the type and level of filtration you want at the point of use.

 Easy to Move – while portability is not something that pops to mind when it comes to water filters, countertop water filters are easy to disconnect from your faucet and just as easy to reconnect to another faucet in your home or install it in another apartment.

Small Size – because these filters were designed to sit next to your kitchen sink, they are small in dimensions precisely to fit well on your kitchen counter.  

Mix of Filter Media – because they’re much smaller than multi-stage under-sink water filters or whole house water filters, the filter cartridges within countertop water filters contain a mix of filter media, which includes granular activated carbon, different blends of ceramic spheres, etc.

Easy to Maintain – countertop water filters don’t require much in the way of maintenance. Once the filters reach the end of their service life, you must change them.

Affordable – affordability both in terms of investment cost and maintenance cost is another reason why countertop water filters are a favourite of many small apartment owners.

Even though they’re small units, countertop water filters have the downside of taking up space on your kitchen counter. Another downside is that they’re not as powerful as multi-stage under-sink water filters, for example. Even so, countertop water filters are a great choice for those looking to solve common water contamination issues in an easy and affordable way.

If you’re looking for a hassle-free water filter system or you just simply don’t have the space to house the bulky hardware that some filters have, the following countertop water filters can be an excellent substitute for multi-stage under-sink water filters:

PurePro CT3000

The PurePro CT3000 is marketed as a 3-stage no-installation water filter, and indeed installing the CT3000 is as easy as connecting the filter tube to your kitchen tap.

The unit features 3 separate quick-change water filter cartridges as follows:

  • a 5-micron sediment filter that removes suspended solids like rust, silt, sand down to 5 microns;
  • a granular activated carbon filter that provides an enhanced reduction of unpleasant tastes and odours and up to 99% chlorine removal;
  • a second granular activated carbon filter, which removes any remaining chlorine and organic chemicals.

The filters in the system are easy to replace without any contact with used filter material. Simply twist off the old filters and twist on the new ones. The filters last from 4 to 6 months, depending on the quality of your tap water and usage.

H2O ePCT Counter-Top Water Purifier

Featuring a single cartridge, the H2O ePCT is a 6-stage countertop water filter. This free-standing filter fits onto the end of standard kitchen taps, making its installation a very easy process. Thanks to its compactness and easy installation, the H2O ePCT is also suitable for use in caravans, motor-homes, boats, etc.

The filter cartridge in this filter contains KDF bacteriostatic media, coconut shell granular activated carbon, riolite, producing up to 6,000 litres of filtered water.

In terms of contaminant removal, the H2O ePCT counts as an advanced countertop filter, which reduces and removes chlorine, chemical by-products, barium, lead, cadmium, chromium, selenium, mercury and other dangerous contaminants.

After 12 to 18 months of use, the filter is replaced entirely, meaning that this model does not have filter replacements.

H2O PCT Counter-Top Water Purifier

Like the ePCT model, the H2O PCT countertop model has a free-standing cartridge with a tap attached to it. This model distinguishes itself through its long service life (18 months), 6-stage filtration, and compact design.

The filter is great for small apartments, boats, caravans, rentals or people on the move. Its contaminant removal efficiency makes this filter an advanced countertop filter that can tackle chemical contaminants as well as some heavy metals.

The filter kit includes fittings and adapters, which allow you to install the filter on virtually any kitchen tap.

The bacteriostatic media within the filter inhibits bacterial growth, while the riolite filter media adds healthy minerals to your tap water.


Countertop water filters have many advantages and in some respects, they are superior to under-sink water filters, especially when it comes to portability and ease of installation. However, depending on the level and type of contaminants lurking in your tap water, a countertop water filter may not always be sufficient.

Although there are a number of advanced countertop water filters offering a multi-stage filtration, depending on your special requirements and water consumption needs, you may still have to opt for an under-sink water filter instead.

If, however, an under-sink water filter is simply a no-go for you, we advise you to purchase free-standing reverse osmosis filters like the Puricom ZIP or a gravity water filter like the Big Berkey.
