The best countertop water filter allows you to provide clean, healthy water for the family while also improving the taste and smell.

Countertop water filters are designed to be affordable, portable and convenient. This makes them some of the most popular home water filters, especially where a whole-house filtration system is not feasible. Here are our favorites for the best countertop water filtration system:

Factors to Consider in the Best Countertop Water Filter

1. What's in Your Water?

Quite simply, you need to know exactly what your water contains to decide on which specific countertop water filter to buy. To find out what your water has, you can reach out to your local water supplier and ask for a water quality report. These documents are readily available to the general public.

It's worth considering water quality reports present a wider picture of what your local area's water contains, and your home's water may be slightly different. Therefore, it would be prudent to do your own water test to ascertain exactly what your water contains. You can buy a reliable water testing kit from your local home improvement store or online.

Different kits test for different water contaminants. |Get a kit with the widest possible range of elements to test, such as bacteria, pH, nitrates, lead, fluoride, chlorine, and not just water hardness. This makes it more straightforward to narrow down to the best countertop water filter for your specific filtration needs.

2. Types of Countertop Water Filters

Even before you start looking at the best countertop water filters, you have to determine which type of filter is most suitable for your needs. Here are the most common filter types you'll find on the market:

a). Water Filter Pitcher

Water filter pitchers are the cheapest and simplest countertop water filters on the market. They look like an ordinary water jug with a filter that traps and eliminates contaminants from the water. It takes anywhere between 5 and 15 minutes for a water filter pitcher to get the job done.

Generally, water filter pitchers hold between 8 to 12 cups of filtered water at a go. Therefore, they need to be refilled from the faucet regularly. Some larger pitchers can hold up to 4 gallons of water, but they might be more difficult to use. Swapping filters is relatively straightforward, as well as cleaning the whole setup; just soak it in warm, soapy water or a dishwasher if the manufacturer recommends so.

b). Faucet Filters

These are designed for a kitchen countertop, usually near the sink, where they're connected to the faucet using a flexible plastic hose. Most faucet filters come pre-assembled and are easy to install. They dispense water at the press of a button, so you don't have to wait for your glass of purified water.

c). Ultrafiltration

This method uses high pressure to force water through a semi-permeable membrane. The membrane material traps larger solids and contaminants as water passes through. The filtration process is more thorough, which makes ultrafiltration countertop filters more expensive than standard ones.

d). Water Distillers

This is a somewhat different method of filtration, where the appliance turns water into steam, then condenses the vapor back into contaminant-free water. Water distillers are efficient at eliminating arsenic, fluoride, lead, viruses and several other contaminants.

e). Reverse Osmosis (RO) Filters

These are more common in under sink water filters. The process-which works similar to ultrafiltration- reportedly can remove up to 99.99% of all dissolved solids. However, reverse osmosis has a pure water to wastewater ratio of 1:4, meaning you lose 4 gallons of water for every 1 drinkable gallon.

3. Size

You don't want to buy a countertop water filter only to find out it doesn't fit in the available kitchen space. It would be best to measure the space near your kitchen sink to determine the best water filter size to buy. This also goes for water filter pitchers, where you don't want one that's too wide or too tall to fit properly.

4. Filtration Ratings

It's important to know the specific elements a countertop water filter can eliminate from your water. All the best countertop filters remove bad taste or odor from water, but not all are created equal. Some filters are more efficient at eliminating chemicals such as chlorine, while others are better with heavy metals like lead and arsenic.

Some filters remove even the beneficial minerals from water, but others keep them in. Some models can also remineralize your water with the recommended amounts of essential minerals during filtration. Ultimately, the goal is to find a countertop water filter with the necessary features for the specific contaminants in your water.

5. Filter Maintenance Requirements

All kinds of water filters require regular maintenance if they are to last a decent while. Different filters come with different maintenance requirements, so go through the user manual to be fully aware of what's required. You must also keep in mind that it'll get to a point where you'll need to replace your filters; they tend to lose plenty of their efficiency as they grow old.

6. Ease of Use

Ease of use relies heavily on the specific design of the countertop water filter. Faucet water filters require a bit more maintenance since they have to be connected to the system before use. However, they are also the easiest filtration systems to use after installation. You only need to press a button, and the device dispenses water instantly.

On the other hand, water filter pitchers require less maintenance. However, they become heavier as they get fuller, making it a bit more difficult to pour water, particularly for children. More so, you also need to refill the pitcher manually.

7. Desired Water Taste

As much as countertop water filters produce cleaner, healthier water, not everyone likes the taste. Some even filter out calcium and magnesium from the water, meaning the water might taste different from bottled water. The taste of filtered water might require some warming up to for some users.

8. Certifications

The best countertop water filters come with the relevant certifications to prove their filters perform as advertised by the manufacturer. These third parties include the Water Quality Association (WQA) and NSF International for quality assurance tests that are quite rigorous and difficult to attain. Look out for such certification to ensure that you get a quality product that's safe for your health.
