What is a Faucet Water Filter?

A faucet water filter is a relatively small device (compared to whole house filters) that leverages carbon block filtration technology to improve the taste and odor of drinking water. The system’s aesthetic reduction includes removing excess chlorine and fluorides.

How Does a Faucet Water Filter Work?

A high-quality faucet water filter will remove contaminants from your tap water in about two to three steps. The purification process is nearly the same as that of a whole house water filter, only that you’ll likely experience relatively low flow rates. These systems work in the following way:

  1. Tap water enters the system through a non-woven screen around the filter. If your source is a private well, you would want to pass the water through a softener before this stage.
  2. The screen removes larger particles such as silt and sediments. Scale buildup (flakes) will also get trapped at this point.
  3. The water moves into the compressed carbon block filter for ultrafiltration. The contaminants removed include fluoride, chloramines, chlorine, and heavy metals such as lead.

Benefits of a Faucet Water Filter

Installing a faucet water filter in your kitchen tap could be the beginning of experiencing various benefits such as:

  • Cost-effective maintenance
  • Eco-friendly living space
  • Pure drinking water, free of pollutants
  • Less odor and better-tasting water
  • A healthy family with nourished skin

The benefits of installing a high-quality faucet water filter in your home are pretty overwhelming. These systems will change everything in your house, including drinking habits. Remember, better-tasting water means a glass will always never be enough. 

Get yourself a filter that removes pollutants from drinking water without interfering with the mineral composition. That way, your children will develop healthy teeth and bones, especially if they are of a younger age group.

Buying Considerations for a Faucet Water Filter

What should you have in mind before shipping this product? Consider:

The Filtration Target

Every faucet water filter has a unique filtration technology that targets specific contaminants. Thus, it helps if you know the type of pollutants prevalent in your water supply system before purchasing. You can take a sample to a local laboratory for scientific analysis and reports.

Number of Users

The design for most faucet water filters is ideal for few users, say a small household of up to three people. If you want a system that serves a big household of up to eight members, buying a whole-house water filter sounds like the best plan. A point of use system may be expensive to maintain in a big family.

Money-Back Guarantee

Some suppliers may ship products with quality defects. Buying from an online store means no time to countercheck the system’s efficiency and specifications. Besides getting the wrong model, you can even get a filter system with some missing components. 

A manufacturer with 100% money-back guarantee terms cushions you from such quality inconsistencies. You can return the defective system for a replacement.

Which Factors Should You Consider Before Buying a Faucet Water Filter?

Handpicking the right faucet water filter from an overwhelming variety of online stores can be quite a daunting process. While nearly all manufacturers and suppliers describe their products as high-quality, not every water filter with a colorful description is worth your money. Here are some buying factors to guide you if you’re a first-timer:


Price varies due to many factors, including suppliers. For instance, physical stores will likely sell these faucet water filters at a higher price than online stores. Similarly, OEM water filters will likely cost more than generic products. 

Other factors that may affect a filter’s price include quality and shipping costs. Whichever option you settle for, ensure that the price matches the filter’s performance and specifications. That way, you can always get back your money’s value.


Reliable warranty terms allow you to get ongoing technical support from the manufacturer or supplier within a certain period. Most products will come with a limited manufacturer’s warranty, but some may also include a warranty from the supplier. 

Always ensure that the warranty terms are clear and cater to your preference. Some homeowners prefer profit free parts warranty, while others will go with a free labor warranty.

Be wary of products that come with unclear warranty information. Moreover, a product with no warranty is likely low-quality since the manufacturer \or supplier can’t even stand taking liability for quality defects.

Water Filter Life/ Capacity

A typical faucet water filter has a lifespan of about a month or two. However, you can get reputable brands such as the best durable product in this buying guide with a lifespan of up to three or four months. 

The filter’s capacity also represents its longevity. Most manufacturers measure the capacity in gallons. The longer the lifespan of the filtration medium, the more likely you’ll have a good experience with maintenance.


The standard certifications that signal a high-quality water filter include NSF and ANSI listing. You can also watch out for IAPMO and WQA certifications, though not shared across all brands. 

However, kindly note that the manufacturer may list a product as certified bit the model number misses in the NSF database. In that case, the system may have its components certified separately with different third parties.

Micron Rating

A product’s micron rating determines the size of pollutants it can trap. Most faucet water filters come with a micron rating of 5.0, but it helps if you get a lower one of about 1.0 or 0.1.

A low micron rating guarantees large and small particle removal such as silt and sediments. Even so, some products will have multiple filter media with different micron ratings at each purification stage.

Filtration Technology

Various filtration technologies target particular contaminants. For instance, an RO (reverse osmosis) water filter will remove traces of TDS pollutants. However, nearly all our products leverage carbon block filtration technology. This filtration is a go-to option for aesthetics reduction of chlorine, fluoride, and chloramines.

Installation and Maintenance

Lastly, you might consider a system’s installation process and maintenance needs. A faucet water filter that is hard to install will likely give you a horrible experience when it’s time to replace the filtration media.

Watch out for systems that come with a clear installation guide and all the components needed for the job, such as faucet adapters. A filter with a one-year free warranty of free labor and ser4ice is relatively affordable to maintain.

The Bottom Line

Waterborne disease outbreaks can be the worst thing that your family can experience. The best solution for any disease is taking preventive measures. All the faucet water filters reviewed above guarantee safe, ready-to-drink water for your entire household within the filter’s lifespan. 

Remember, drinking from an expired filter is similar to drinking untreated tap water. Each product is unique and reflects the needs of different homeowners.
