What To Consider When Shopping For A Good Faucet Water Filter

To help you be able to get a faucet water filter, we have created a buyer’s guide covering the most important aspects of a faucet water filter. Here are the things that you should look for:

Design and Look:

One of the most important aspects of buying faucet water filter is how the unit actually looks. If you are placing one of these filters directly in your kitchen, you don’t want the centerpiece of your kitchen to be an ugly device attached to the faucet of your tap. Eye appeal is extremely important and it is definitely a good idea to take a look at a few different filters in order to match the look of your kitchen and make sure that you are getting something that doesn’t stand out in a bad way. There are many different colours of water filters available and in order to choose the right colour it is a good idea to look at the other appliances that are in your kitchen. Generally, you’re going to find that the main colours for faucet water filters are black, white, chrome and stainless steel, which are usually the same colours that things like fridges, stoves, microwaves etc. come in.


If you’re thinking about buying a water filter, you are going to want to check to see what size of filter fits onto your tap. It is important to look at your tap’s measurements in order to make sure that your tap is compatible with the filter that you’re looking at. If you have owned your sink for a while, you might have to go back and look at your receipt or the original box for the dimensions in order to make sure that the filter can fit. You can also look up the type of sink that you have and see if you can find some dimensions online.

Filtering Ability:

When you’re buying a faucet filter, you are going to want to find something that takes as many chemicals out of your water as possible. Chlorine, lead and fluoride are the most common things that you will find in water so make sure that you at least get a filter capable of assisting in the removal of these. If you really want to make sure that you have a quality filter, you can also make sure that the filter filters out things like lead, cryptosporidium and even things like bacteria, giardia and cysts. One final thing that you might want to check is that the water filter is BPA free so that you can be sure that you’re getting a filter that is as healthy for you as possible.

Filter Replacement Cost:

When you purchase a water faucet filter, you should definitely make sure that you take a look and see how much water the filter is actually capable of filtering before it needs to be replaced. The more water that is capable of being run through the system, the better, so long as the filters you are looking at have equal filtering capabilities. It is a good idea to check out the cost of filter replacement before you purchase a unit as filter replacement will be a long term expense for you and checking out this price can definitely save you some money down the road.

Top Faucet Water Filter Brands:

Due to most people not liking the taste of city water, you’re going find that there are a lot of brands available out on the market. It is important to recognize which brands are quality and which brands are just in it to make some money. One of the best ways to be able to tell which brand makes good quality products is to check out things like customer reviews, different kinds of products that the manufacturer sells and how comparable their prices are with other competitors. Buying from the most well-known brands is always a safe bet, but there are many quality brands available if you take the time to look for them.


One thing that you are going to want to consider when choosing a water faucet filter is the temperature that the filter is capable of being used at. If you are attaching this filter onto your kitchen sink and use the filter for hot water only, you’re especially going to want to pay attention to the temperature range of the product. A lot of filters on the market aren’t supposed to be used with hot, which means that you definitely need to be careful when picking out which filter you want to buy. In order to be on the safe side of things, try to find a filter that has a wide temperature range and one that actually gives you the degrees that the filter is capable of being used at. Seeing the actual numbers can give you some peace of mind with your purchase and you should consider looking for some.


If you are buying a faucet filter and are using the filter to filter water that is being passed through at a high-pressure range, you may want to try to find a product that has specs for what PSI the filter can be used at. Is important to keep in mind that if water travels at a high rate of speed through the filter, it is likely not going to be as pure as something that goes to the filter at a slower rate of speed. The more layers a filter has, the more effective the filter will be when water is travelling at a fast rate of speed. However, layers definitely slow down the flow of water so you will have to take that into consideration.


If you want to ensure that you’re going to save some money down the road, you may want to make sure that you get some accessories with your purchase. Sometimes, you will find that water faucet filters come with replacement filters and adapters. Depending on what you are doing in the sink, you might find that adapters are extremely helpful as they can change the flow of the water to suit your needs. If you’re filter comes with accessories such as adapters, you might also want to check to see how easy they are to attach as some of them just screw on, while others can be a little bit more difficult.

Battery power versus battery-less designs:

One area that differs a lot between filters is whether or not the filter has a battery in its design. Generally, filters that have batteries in their designs will have sensors on them which will let you know when the filter needs changed inside of the unit. This sensor can be handy, but it is important to keep in mind that you are going to be paying for the price of batteries down the road. It can be quite hard to determine how much water has gone through the filter and when it needs changed without the use of this sensor. It is for this reason it is recommended that with battery-less designs you change out the filter automatically after a certain period of time has passed. This method, unfortunately, isn’t always the best as you might end up replacing the filter too early, which eats away at any savings that might have been had by skipping out on a battery powered unit.

On/Off Switch:

One thing that you may want to consider when buying a faucet water filter is whether or not the faucet water filter can be switched off. When you are doing something like boiling water, you don’t really need to use a water filter as boiling the water will help to remove harmful bacteria from the water. It is for this reason, you might want to try to find a faucet water filter that has an on/off switch in its design. There are all sorts of these available on the market, but not all designs have this in them. A switch may cost you extra money to get, but it can also prolong how long the filter lasts for.


Technology makes everything better and such is the case with faucet water filters. There are plenty of water faucet filters that have Bluetooth in their designs and there are plenty that don’t. Rather than having to rely on a light on the side of your tap or some kind of a switch to let you know when you’re filter needs replaced, you could get a Bluetooth design instead. Bluetooth designs let you keep track of your filter usage on your smart phone. Other nice uses for this technology include allowing you to be able to keep track of your daily water intake as well as how much water you’re using altogether. This technology is great for our world as it helps users to be able to see when and where they are wasting water. This technology can assist with keeping your water bill and preserving what good water we have for future generations of humans.

Water flow:

If you are in the kitchen a lot and filling up things like pots and cups with water on a regular basis, you’re going to want to consider water flow when you are buying a water filter. No matter the unit that you purchase, you are going to find that there is somewhat of a decrease in pressure. It does take some time for a filter to filter water properly.  However, some faucet water filters are faster than others. It can be extremely hard to figure out how much of a pressure decrease a faucet water filter has without trying it out and comparing it to other filters. Generally, the best way to figure this out is to look at comments from previous customers and see if you can find someone who has had both of the products. Luckily, faucet water filters aren’t extremely expensive so if you are seriously worried about not having enough water flow, it won’t cost you a fortune to try more than one faucet water filter before deciding which one is the best option for you.


The shape of a water filter doesn’t have a huge impact on a lot of people. However, if you are using the sink to clean large objects, then shape may play a huge role in preventing your access to the sink. If you are scrubbing things like large bins inside of a sink, you don’t want something that is hanging way down off of the tap and preventing you from putting things into the sink. It is important to keep in mind that some water filters are designed to filter water with a unit that protrudes straight down from the tap, while others filter off to the side. You will have to decide the better option for you, but it is important to know that the two options exist.

We hope that this article has been helpful to you and that you now feel as though you will be able to pick up a quality faucet water filter. Always make sure that you take measurements first or look to see what the measurements are before you purchase. It is a good idea to make sure that you have all of the tools you need in order to be able to install the unit when it arrive so that you can enjoy clean water as soon as possible.
