Faucet-mounted water filters are fast, convenient, and attractively priced filtering solutions. They fit straight onto your tap, meaning that purer water is there right when you need it. This helps encourage better habits and more daily water consumption—plus, the activated carbon used in filtering means no more chlorine aftertaste, offputting smells, or bitter flavors from sediments.

While not every tap can fit a faucet-mounted filter, standard kitchen fittings are normally compatible, and there is a range of different filter types and brands to choose from. To help decide what works best for you, here are the products which made the cut in our list of best faucet water filters style=”font-weight: 400;”>.

Choosing the best faucet water filter – It’s all about efficiency

I see you. You’re a thinking person. While others are running back and forth from their refrigerator, constantly filling and refilling their water pitcher filters, you’ve made the intelligent decision to remove all unnecessary effort from the filtering process, by installing a filter right where you need it—on the faucet itself.

Congratulations! It’s a smart choice. Faucet-mounted water filters are reliable, efficient devices that provide the same benefits as other types of kitchen water filter, without the need to move around your kitchen or wait for a reservoir to fill.

Efficiency is an important quality in any water filter. Because kitchen filtering solutions are designed to improve the taste and quality of your water, and not provide any water safety assurances, most people look to filters as a way of encouraging a healthy, more beneficial lifestyle. The easier and more convenient it is for you to access great-tasting water, the more likely you are to get your recommended intake on a daily basis.

It’s true that other kinds of filter systems—such as under-sink and point-of-entry filters—do away with any visible filter component at all, treating your water before it hits the tap. However, these solutions require installation, often with the assistance of a professional. This means extra time and possibly incurring labor costs. So, if you’re looking for a filter that you can start using straight from the box, a faucet system is a good way to go.

How do faucet water filters work?

Almost all faucet water filters remove contaminants from drinking water via adsorption. This refers to the ability of some materials to bind others to their surface upon contact. Among the best adsorptive materials around is activated charcoal, which you’ll find ground down and expertly structured inside the cartridge of your faucet filter.

When water from your tap and through the filter, organic, carbon-based contaminants in the supply make contact with activated charcoals large surface area and are adsorbed, reducing or removing a number of common pollutants. These include chlorine,

While the treatments applied by your local water supplier should remove potentially harmful materials like protozoa and viruses from the water source, this process can leave behind trace chemicals and sediments that worsen water taste and smell. Adding a faucet filter to finish off the filtering process leaves you with H2O that’s not only safe but fresh-tasting.

In terms of filtering technology, there’s not too much difference between a pitcher filter and a faucet-mounted filter. Both mostly use activated carbon to remove organic compounds and improve the taste of water.

Aside from where they’re placed in your home, the main difference between these two common filter models is that faucet systems use water pressure to push water through the filter cartridge, rather than relying on gravity. This allows some faucet filters to claim slightly more filtering power than pitcher models.

Due to their design, many faucet filters are also able to incorporate larger filter cartridges that pitcher models, leading to a longer period between replacements—and another boost in efficiency!

Here’s an important question. There are certain faucets that are not compatible with faucet-mounted filters. In particular, faucets with pullout hoses and those with adjustable head settings may not accommodate the way that many filters screw onto the tap. The same goes for vintage or bespoke design faucets.

Most filters will come supplied with adapters that replace your faucet’s aerator (the very end of the faucet) and help thread the filter directly onto the tap. So, if your faucet has an unusual aerator, then you might struggle to find an appropriate adaptor.

Also, it’s worth considering the robustness of your sink system. Faucet filters and a small, albeit additional weight to your tap, so if you happen to have a very flimsy model, it may strain the fittings and make leaks more likely.

Depending on the hardness and purity of your source water, faucet-mounted filter cartridges generally filter around 100 gallons, which for most people, equates to about three months of use. Many filters will have their own advice on this, as well as indicators on the device to help you track usage over time.

Once that time is up, you’ll need to replace the filter cartridge. Because adsorption binds contaminants to the carbon’s surface, once that surface is filled, there won’t be any filtering occurring inside your device.
