What is a Countertop Filter?

A countertop filter is a point-of-use filtration system that’s typically installed in the kitchen. The unit sits on the counter and attaches to the kitchen faucet, typically with a diverter tab, so you can switch between filtered and unfiltered water.

These compact systems offer tasty, clean water at an affordable price. They’re the ideal solution for renters, travelers, people living on the go and those with small apartments.

Countertop filters are also surprisingly efficient and can target an array of contaminants but aren’t a comprehensive filtration system if your water is doubtful. They work best with city water, as these units are effective at filtering chlorine, fluoride, chloramines and lead among others.

However, for untreated private water sources like well water or rainwater, it’s best to use the countertop system in conjunction with other water purification methods. This ensures that the water is made bacteriological safe and contaminant-free. No single filtration system can remove every contaminant in the water, so best practice is to use a combination of methods.

How Does a Countertop Filter Work?

Most countertop filters connect to the kitchen faucet and have their own spout, which dispenses the treated water. They use the water from the faucet to produce filtered water. These systems work automatically, meaning that you won’t have to check on water levels and fill any reservoirs up.

However, some can be stand-alone units that don’t require connection to the faucet. These models work more like filter pitchers and will need to be manually filled and monitored.

Countertop filter system explanation

How a countertop filter works. This is the APEX 5-Stage Model.

Most countertop filters incorporate several filtration layers which work together to target a bigger variety of contaminants. These mediums include activated carbon block (ACB), granular activated carbon (GAC), ultrafiltration, KDF-55 and others.  

Countertop filters may be small, but they’re effective and efficient. These systems typically use multi-stage processes to remove a wide range of contaminants. Some contaminants that countertop filters can remove include:

  • Sediment
  • Rust
  • Lead
  • Industrial chemicals
  • Pesticides and herbicides
  • Volatile organic compounds (VOCs)
  • Microorganisms
  • Chlorine
  • Bad taste and odor
  • Atrazine
  • Chlorobenzene
  • Methoxychlor
  • Benzine
  • Hardness minerals
  • And many more…

Some countertop systems utilize reverse osmosis (RO), which removes almost all impurities from the water. RO systems also demineralize the water and produce a large quantity of wastewater but are highly effective at purifying your water.

What to Consider When Buying a Countertop Filter

When choosing the best countertop filter for your home, there are several factors to take into account. Some of these are as follows:

What’s in my water?

As no single filtration system targets 100% of contaminants in water, you’ll first have to know what’s in your water. This will then help you find the best filtration medium for that.

There are a few ways to check you water quality. You can do a home water test using a kit like this one, or request a water quality report from your local water supplier. Another option is to request a water quality test by a professional laboratory.

These tests will indicate the levels of total dissolved solids, hardness compounds and other impurities. If you want to skip this step, purchase a general filter that targets a wide variety of common contaminants. If you have city water, you’d probably be looking at a filter that removes chlorine and lead.

 Contaminant Removal

Now you know what you want to remove from the water, consider the types of filters that target those specific contaminants. This will help you narrow down the choices available.

Type of Filter

The next thing to consider is the type of countertop filter you prefer. We’ve already mentioned above that these filters come in two main types:

  • Sink-top filter: These are the most common countertop filter types. They attach to your faucet and diverts the water into the filter when required. They work on demand, much like an under-sink water filter. Sink-top filters are located next to the sink, require basic installation and aren’t portable.
  • Gravity-fed filter: These work exactly like filter pitchers. You have to fill water into a reservoir located above the container. From here, water filters through into the container by force of gravity. These models are portable and don’t need to be located in a specific spot in the house. They’re perfect for various locations, including when traveling and in offices.

As each has its advantages and disadvantages, carefully consider which type suits your needs best.

Cartridge Lifespan

The lifespan of the filter relates to the filtering capacity of the system. Most countertop filters typically last around 6 months, while some can last up to a year or more.

However, these are just guidelines and can vary depending on your water quality and usage. Pay attention to the water flow of the filter and any changes in taste and smell, as this can indicate that your filter requires replacement.

More frequent replacements mean higher maintenance costs, so factor this into your purchase decision.


Countertop filters range in price, with the most expensive models typically featuring reverse osmosis filtration. However, don’t just look at the initial cost of the filter. Consider the cost of ongoing maintenance as well. A more affordable filter could have expensive replacement cartridges and vice-versa. Take this into consideration when purchasing.

Pros and Cons of a Countertop Filter

No product is perfect, and countertop filters are no exception to this rule. These filters come with several pros and cons.

Countertop Filter Pros:

  • Affordability: Unlike most other filtration systems, countertop filters are relatively affordable. You can purchase a high-quality model for between $60 to $120. This makes it an excellent option if you’re on a budget or don’t want to invest in a filtration system.
  • Compact: These systems are quite small and take up only a little of the countertop space. The compact design offers benefits to people living in smaller houses and apartments who may not have the space for whole-house or under-sink filters.
  • Efficient: Despite their small size, these units are highly efficient and remove most of the common contaminants in water. A high-quality countertop filter offers excellent results, significantly improving the taste and smell of water.
  • Impermanence: Installing a countertop filter doesn’t require a commitment in the sense of structural changes. Installation is easy, with no need for plumbing. All these makes countertop filters ideal for quick and easy filtration with minimal commitment.
  • Portable: The ability to pack up and carry a countertop filter with you gives it added uses and versatility. Regardless of the type of filter, countertop systems are designed to be portable and can easily be taken on holiday with you, to the office, or when camping or hiking.

Countertop Filter Cons:

  • Intrusive: Although they don’t take up much space, they do require space which can be inconvenient in a small kitchen. If this is the case, consider a faucet filter or under-sink filter.
  • Aspect: These units are typically designed to suit a variety of kitchen aesthetics, but you may not like how the filter looks in your kitchen.
  • Slow Flow: This can vary depending on the unit, but in general, countertop filters are known for having slow flow due to the on-demand filtration style. The type of filtration medium can also impact flow.
  • Single Point:

Countertop Filter vs. Under-sink Filter vs. Faucet Filter

There are many types of smaller filtration systems on the market, each with its own pros and cons. Choosing the right filter can be difficult, but knowing your options will help you to filter through them (see what we did there?).

From smaller filtration systems, two other popular types are the faucet filter and under-sink filter. Here’s how they compare:

The following image shows how countertop filters compare to faucet filters and under-sink filters in relation to their pros and cons:

Should I Buy a Countertop Filter?

Countertop filters are a very good solution if you want clean drinking water easily. This would be a good filtration solution if:

  1. You want an affordable option that doesn’t require a big investment.
  2. You want a less permanent option that allows you to easily install and remove the system as required.
  3. You only want to target drinking water coming out of one point, especially in the kitchen.
  4. You’re looking for a portable filter that can be taken to different locations if needed.
  5. You’re a renter and don’t want to make structural changes to the house.

The Bottom Line

It might be clear by now that countertop filters work like water filter pitchers, providing clean, pure water without too much commitment and cost. Because no single model is comprehensive, choose carefully according to the contaminants in your water, budget, aspect, and space.

Testing your water is the best first step to take before deciding on which filtration system to purchase.
