Things to Consider

Now that you’ve seen our faucet water filter reviews, it’s time to take a closer look at the various features and aspects of each faucet water filter you need to look out for when shopping for your next system. This buying guide will take you through individual aspects of faucet filters like flow rate, dimensions, and materials to help you understand the importance of these aspects and make a smarter and more informed decision when you decide to place an order for your next faucet water filter.

Advantages of having a faucet water filter

There are many different advantages to having a faucet water filter, here are just a few:

  • Healthier Water – The number one advantage of investing in a faucet water filter is the fact that it will provide you with healthier, safer, cleaner water. These filters work to clean out unwanted elements and harmful presences in your water, cleaning it of chlorine, heavy metals, toxins, contaminants, bacteria, and more. This means the water you drink and wash with will be cleaner and safer overall, offering super peace of mind for you and your family.
  • Convenient – Many people make use of old-fashioned filters that involve manually pouring the water into a separate device and then filtering it away from the faucet. These devices can waste time and be quite inconvenient when you’re in a hurry and just want some clean water right away. Faucet water filters hook right onto your faucets, so you don’t have to do any extra work. They’re very easy to install too, in general, offering big life improvements after just a few minutes of set-up.
  • Improves Taste – Many people struggle with the taste of the water from their home faucets. Depending on where you live, certain elements in your water might give it an unpleasant taste or odor. By filtering your water and removing those undesirable elements, faucet water filters are able to actually improve the flavor of your water and remove any nasty odors too, making your faucet water much more palatable.

Features to consider when choosing a water faucet filter

Top 7 Faucet Water Filters: Fuss-Free Filtration for Softer and Cleaner WaterThere are several things to think about when choosing your water faucet filter. The filter life, flow rate, dimensions, features, and materials used to make the filter are just a few aspects to think about. It’s important to really consider these individual factors when shopping for a new filter in order to make the best decision for your home and choose a filter you’re going to be happy with for many years to come.

Filter life

This is one of the most important aspects to think about when buying your water faucet filter. Some models will come with filters that can last a long time. The filters in the pH REGENERATE Faucet Water Filter Purifier, for example, can last a whole year before they need to be changed, but those found in other models aren’t quite as long-lasting. It’s important to remember that new filters cost money, so cheaper models might not always be very cost-effective if they have short filter life. In general, you want to try and find a model with the longest filter life possible at the fairest price. Filter lives of 6 months and above are generally very good.

Flow rate

Flow rate is another important aspect to consider, especially if you do a lot of cooking or like your faucets to be as rapid and reliable as possible. Flow rate tells you how much water passes through the filter each minute. Some filters are faster than others. The Aibika Water Faucet Filter System, for example, has an impressive flow rate of 1.5GPM, meaning that it can fill up bottles and cups a lot more quickly that a model with a lower flow rate.

Filter stages and filtration media

This might be the most important feature to think about when shopping for your next faucet water filter. If you’re investing in a filter, you want it to work as strongly as possible, truly filtering the water you drink and use each day and enjoying a better quality of life as a result of purer and cleaner water. Some filters actually aren’t as strong as others, while some feature cutting edge technology and can really improve the quality of the water in your home. The Engdenton Faucet Water Filter features an Activated Carbon Fiber filtration system, which is one of the strongest around. The Spardar Faucet Mount Filter, meanwhile, offers a 5-stage filtration system and is very efficient at removing toxins and contaminants. The pH REGENERATE Faucet Water Filter Purifier is even more impressive, actively purifying water by adding new minerals and boosting the pH.

Materials and construction

The whole point of a water filter is to make your water purer and cleaner, so you definitely don’t want to buy one that is made of poor quality materials which could actually affect the taste of your water and reduce its overall quality. In general, stainless steel is a good material for the housing as it helps to ensure that your filter is durable and long-lasting. BPA-free materials, like those used in the pH REGENERATE Faucet Water Filter Purifier, are excellent too at ensuring that your filter is safe and secure.

Is it compatible with your faucet?

Top 7 Faucet Water Filters: Fuss-Free Filtration for Softer and Cleaner WaterNobody wants to buy a faucet water filter that doesn’t actually fit their faucets. It’s important to note that not all filters are compatible with all faucets. Some are designed to only work with certain faucets, and others may require extra accessories and hardware to work on certain sinks. It’s vital to look at the dimensions of each filter to see if they will work in your home and consult the product details to see if the model you like will actually fit your faucet.

Operating temperature

It’s also important to note that water filters also have optimal temperatures too. Some of them actually won’t function on water that is too hot, so it’s important to consult the specifications closely and ensure that you’re buying a model that really works for you. Like with any home appliance or gadget, it’s essential to really read through all the information on a faucet water filter system and know all the details before making a purchase. The slightest issue or incompatibility could cause big problems and lead to you wasting money and time, so be sure to choose wisely.

How to get the most out of your new faucet water filter

These filters provide you with purer, cleaner water and can really improve your quality of life. If you choose a bathroom water filter, like the CuZn Bath Ball Faucet Filter, you’ll see big benefits when taking baths or washing. Finally, remember to change the filter regularly to ensure optimal performance.


In general, most faucet water filters will only work with certain faucet types and these do not usually include pull-out faucets. Most models of filter will not work with hand-held or spray-style faucets either, or those with sensors. As previously stated, it’s important to look at all the details of each model and even contact the manufacturer if needed to ensure you’re buying a filter that will actually work with the faucets you have at home.

You can use these filters anywhere you have a faucet and want to benefit from cleaner water. In general, people tend to use them in kitchens in order to have higher quality and tastier drinking water, as well as for cooking and cleaning purposes, but the CuZn Bath Ball Faucet Filter, for example, is designed for use in the bathroom in order to provide softer water for your hair and skin when you bathe.
