Faucet Attach Filter
Reviews

While there are several types of filters to choose from, faucet water filters are a popular choice due to their compact form factor, easy-installation, and entry-level price point relative to other options. To help you pick the best faucet water filter, we’ve compiled details about several systems and created a buyer’s guide with additional information to help with your decision. 

What is a Faucet Water Filter?

Faucet water filters attach directly to a sink’s faucet to remove contaminants right before water comes out of the tap. Filters of this nature are considered point-of-use, since the water is filtered when and where you use them. The benefit of this is that it ensures the water won’t be contaminated from pipes within your home, which can occur if you use a whole house system that filters water at the main water line.

Types of Faucet Water Filters

Not all faucet water filters look or work the same way. Most notably, these systems come in two distinct form factors that relate to how they work and their performance:

Faucet Attachment With Built-In Filter

Some faucet water filters have a self-contained filter within the unit that’s screwed onto the faucet, meaning there are no hoses or external systems — all the filtration happens at the tap. These usually feature a carbon filter, which catches contaminants as water passes through before coming out of the faucet. Since there is only one filter, some contaminants may remain which is why these systems are on the lower end of the performance scale relative to other options.

Faucet Attachment With External Filtration Unit

These systems have a screw on attachment that uses a series of hoses and an external filtration unit that sits on a nearby countertop. When you turn the faucet knob, water will go through one hose that takes it to the filtration unit where contaminants are removed, then filtered water is pushed through a second hose that leads back to the faucet. The process is a bit more complicated than the other option above, but these systems can offer a higher level of contamination removal by utilizing multiple stages.

Buyer’s Guide for Faucet Water Filters

Looking at faucet water filter reviews and comparing high-level details is a great start to choosing the best system for your home, but for more information we’ve created this guide to help with the process. Find out exactly what a faucet water filter is, how it works, and factors to consider when comparing systems.

How to Choose the Best Faucet Water Filter

When looking at faucet water filters, here are the factors you should consider:

Faucet Attachment Type

With the information above in mind, consider whether you’d want an attachment with a built-in filter or one that uses hoses to connect to an external unit. A hose free option may be more aesthetically pleasing, but might come at the cost of reduced performance.

Performance

Check your local water quality report to see the contaminants present in your tap water, then use that information to find faucet water filters certified to address those concerns. Don’t rely on claims, make sure the system you’re considering has actually been tested and certified by a third-party group like NSF, IAPMO or WQA.

Cost

Faucet filters with a built-in filter usually come in at a lower price point than ones that use an external unit, since the built-in filters may offer a lower level of filtration. For reference, systems with a built-in filter may cost around $30 while options with an external unit can cost $70 or more depending on the level of filtration.

These are the fundamental factors to consider when looking at a faucet water filter, but there may be other aspects specific to your situation. Having background knowledge of these systems combined with reading faucet water filter reviews should give you the information you need to make the right decision.
