How Countertop Water Filters Work

Countertop water filters are tremendously user-friendly devices, requiring little by way of installation and easily moved from one location to another. But – although they are simple from a user perspective, countertop water filters employ a complex process to remove debris and contaminants from your drinking water.

The first phase of the filtration process is strictly mechanical. The water is first pressed through a filter that features small pores, or holes – typically between .1 and .3 microns. These holes act as a sieve, capturing any debris such as sediment, rust or other particles that might be present in your water. In addition, some microorganisms like bacteria, viruses or parasites may be large enough to filter out during this mechanical stage.

Once the mechanical phase is complete, the next step is water softening. This is accomplished by using ion exchange resins that can remove magnesium and calcium in your water, which makes it softer. In addition, this part of the process can eliminate both heavy metals and other toxins. Softening your water has many benefits, including shinier glassware, silverware, etc., along with softer skin and cleaner, smoother hair.

Check out our Water Softener Article for more in-depth information regarding water softeners.

The third step in the process is activated carbon filtration – many people consider this the most important part of the process. Activated carbon has been treated to maximize the number of its pores. As water moves through the activated carbon filter(s), those pores remove organic contaminants in your water, such as chlorine, disinfectants, pesticides, volatile organic compounds, herbicides, etc. Because of its large adsorption surface, activated carbon is relatively common in various types of water filters – it’s both effective and widely employed in removing various types of water contaminants.

In addition, depending on the countertop water filter model you choose, there are several additional optional filtration steps:

1. Alkalization – Infrared rays can be used in this process to ionize the acidic components of your water, making it more alkaline.
2. KDF filtration – KDF filtration even further neutralizes and reduces elements like mercury, iron, chlorine, hydrogen sulfide and lead that may be found in water. Adding KDF filter media can also extend the life of your carbon filter and lower overall maintenance costs for your countertop water filter.
3. Silver filtration – Adding a silver filter can help ensure you’re eliminating any remaining microorganisms, toxins and heavy metals that previous filtration steps may have missed. Adding a colloidal silver filter can also cut down on turbidity, and it further helps with taste and odor issues.
4. Remineralization – This is a rare step, but some users like to use a remineralization cartridge to release calcium and magnesium ions into the water, further improving its health benefits. In addition, many users prefer the taste of remineralized water.

One thing to keep in mind: unlike many other water filter types, most countertop systems refrain from using reverse osmosis.

Most countertop water filter models include a tube that attaches to your kitchen faucet – simply removing your faucet’s aerator and screwing in the adapter in its place will generally get you up and running. Filtered water will now flow from your faucet.

 

Advantages of a Countertop Water Filter

Some might say that countertop water filters are life-changing. That point is debatable, but for sure, using a countertop water filter in your home has many advantages, including the following:

• It can save you money – Over time, the purchase of a countertop water filter can save you a great deal of money when compared to the continued purchase of bottled water over time.
• It’s easy to install and maintain – Your countertop water filter simply needs to be connected to your faucet, and you’re all set up and ready to go.

• It boosts your water’s natural properties – Depending on the filter you purchase, your model may filter out hazardous sediment and pollutants while maintaining the naturally occurring, healthy mineral deposits that help balance the water’s overall pH.
• Your water will taste better – Because it can remove many common pollutants and irritants, including your water’s chlorine residual, your water will both smell and taste better once you begin using a countertop water filter.

It’s also been said that filtered water can help boost your immune system and even stimulate weight loss. For certain, when you remove contaminants and chemicals, you also alkalinize your water, which makes it better for your overall health. In addition, alkaline water is known for its anti-aging properties, it boosts your immune system, supports healthy digestion and effectively hydrates your skin. Some water filters offer the specific option of a filter that is designed to make your water more alkaline, so if this feature is appealing, make sure to look at each model for how well it performs when it comes to alkalinizing your water.
• Your water will be safer – Many contaminants, like lead, for example, can be a cause for concern in some tap or well water, but using a countertop water filter can help ensure that you aren’t ingesting poisonous substances.

Overall, most users agree that countertop water filters are highly effective additions to their households – effectively removing sediment and contaminants and reliably delivering clear, crisp, great-tasting water. They save money, are easy to install and help ensure the health of everyone in your home. In addition, they’re low-maintenance and relatively inexpensive to purchase, so there’s little risk involved in making a countertop water filter purchase.

 

Countertop Water Filter Installation and Maintenance

Unlike under sink water filters, which require a great deal of planning and measuring, installing a countertop water filter is quick and easy. If you have an adjustable wrench, make sure to have it on-hand in case you need it, but many models come with their own plastic wrenches designed for use during installation.

Here’s a step-by-step guide to getting your filter installed:

1. Set the water filter beside your faucet, and make sure it’s close enough to allow for the water line to connect the filter and faucet without interfering with use of the sink or faucet.
2. Take the aerator out of the faucet.
3. If your faucet features an outside thread, go ahead and connect the filter. But – if your faucet features an inside thread, you’ll first need to connect the adapter and then screw in your filter. Don’t try to screw it in too tightly – it’s easy to mistakenly cause damage. Also make sure to use a washer.
4. Attach your diverter valve to the faucet. Now, when you turn the water on, it should flow from the faucet.
5. Last, rotate the diverter valve so that water now flows from the water filter. And you’re done – installation complete!

Once you’ve installed your countertop water filter, you’ve completed just the first step. Every model described here – in fact, every model on the market – will have regular maintenance needs. For example, make sure you understand what your unit’s filtering capacity is so that you’re able to change out the filter at an appropriate point; if you’re not regularly changing your filter, you’re essentially drinking the same water you’d get out of the tap.

Make sure you understand how quickly your countertop water filter will reach its capacity; a wide range of filter capacities is available. In addition, understand how your filter is configured – for example, some units feature four consecutive filters to thoroughly clean drinking water, and all four of those filters would need to be replaced at likely the same time. Just make sure to put yourself on a regular schedule for filter maintenance and you should be fine.

Some models may come with features that help you track when the filter needs to be changed – for example, a counter that allows you to measure the number of gallons filtered or a color-coded system that helps gauge remaining filter life.

Other than changing out filters, you may, from time to time, decide to switch out various parts of your filter, like the external case, the spout, tubing, O-ring, etc. These parts are generally easy to find either online or at a home improvement store, and most repairs/replacements can be made quickly and easily. As always, if you aren’t a DIY person, you can always get help with any repair or replacement more complicated than the filter.

In addition, you’ll want to clean your filter periodically, using only gentle cleaners and avoiding abrasive agents like bleach or steel wool

Being observant about your countertop water filter’s performance and taking the time to periodically update or replace parts can help keep your machine running at peak performance.

 

Best Countertop Water Filter Buyer’s Guide

You will be able to find a wide variety of countertop water filters on the market, so it’s important to know what your water filtration needs are, along with what specific qualities can help you meet those needs. Below, we’ve compiled several key considerations you’ll want to keep in mind as you make your choice.

1. Size and filtration needs – If you’re purchasing a countertop water filter like those reviewed here, make sure you take inventory of your countertop space so that you know the model you choose will have plenty of room to sit beside your faucet. And besides the physical size of the water filter, you’ll also want to consider its filtration capacity; at what level do you need it to filter your water? All of the units described here can remove sediment, some heavy metals, taste and odor. But each model has its own strength. For example, some are better at removing chlorine, while others are stronger at filtering out chloramines. Some filters will remove harmful contaminants, but also healthful minerals, while other models add back in minerals that have positive health effects. In fact, before you make your countertop water dispenser purchase, you may want to have your water tested so that you know exactly what’s in it and what you’d like to filter out. A simple water test kit can tell you a lot about your current tap water – its heavy metal concentration, how hard it is, its pH and more. Once you know what’s there, you can find the best water filter to remove what you need.
2. Ease of use – As a general rule, countertop water filters are extremely easy to use, which is part of what makes them so attractive – all you have to do is turn a switch and then turn on your faucet. But make sure you research exactly how that mechanism works for your chosen unit so that you can ensure a smooth user experience for everyone in your home.
3. Price – You want to make sure you’re getting the best value for your dollar, and countertop water filters come in a wide range of prices. And the best machine for you isn’t necessarily the most expensive. This is where knowing what needs to be filtered from your water can help you make the best decision – for example, some models are especially good at filtering out heavy metals, so if you need that feature, those models might be a good choice for you. However, other models may be better at filtering out chemical agents like pharmaceutical residuals or pesticides, so if you know you need that level of filtration, you can concentrate on models within that category.
4. Taste of the filtered water – All countertop water filters will provide a healthier drinking water for your family, but the resulting taste can be all over the map. It’s not unusual for some users to report that they’re not crazy about the taste of their filtered water. Part of that is the fact that people have become used to the taste of their tap water and are put off by the difference in taste – this is especially true when it comes to chlorine. It can take some time to get used to drinking non-chlorinated water. But keep in mind that countertop water filters also can eradicate some of the healthy minerals in your tap water, which also affects the taste.

 

Summing It Up

This guide should give you a head start when considering which unit to purchase as you read through various countertop water filter reviews. With the right research, and considering the variety of models to choose from, you can find the best countertop water filter for your home and be well on your way to cleaner, better-tasting water.
