If you are someone who is unlucky enough to live in a poor quality water area or just want to make sure that the water you are drinking is free of impurities, then it is time to buy yourself a good quality water filter.

Most people assume that water from the tap is safe to drink so few of us ever stop to consider just what is in our water. We have all heard of soft and hard water and know of a handful of pollutants like calcium and chlorine that either damage our pipes or are actually harmful to our bodies.

Very few of us actually realize just how many chemicals and pollutants there are to be found in our tap water. Some chemicals such as potassium permanganate as can even cause skin irritation according to the World Health Organization.

While others such as iron and manganese don’t cause harm to our bodies in small doses, they do put extra work on our kidneys and liver as they work to filter the abundance of minerals out.

Since buying expensive bottled water is not an option for many families, the solution is to buy a good quality water filter to make sure that all the water you are drinking from now on is totally safe and as fresh as a mountain stream.

Faucet Water Filters Explained

Research shows that people think of water filtration systems as being inconvenient and expensive. They also think that the systems designed for households are not as effective at removing pollutants as they claim. After all, anyone who has ever read anything about industrial tap water filtration will have read about the huge range of water purification that our tap water undergoes. This includes things like UV filtration to kill bacteria and the use of numerous chemicals to remove pollutants from the water.

However, this viewpoint is simply wrong. Modern household filtration systems are extremely effective in removing all those unwanted chemicals and pollutants from our water. They utilize state of the art designs and filtration materials to clean your tap water with little to no reduction in the flow rate.

A faucet water filtration system is a small filter that attaches to the faucet to remove all of the impurities and pollutants from your tap water without interrupting the flow too much. They vary in price quite considerably, but generally, the higher the price the better standard of filtration you are getting for your money. The most modest filtration systems start from as low as $30 and go up from there.

What are the different designs of water filters available?

It is inevitable with so many different companies producing water filters that there would be so many differing designs on the market. The main designs are as follows:

Single barrier systems such as granular-activated carbon filters use one filtration material to filter out all those nasty chemicals and harmful bacteria. Carbon filters are one of the best single barrier filters on the market today.

Multi-barrier systems as the name suggests, use several different filtration materials or processes to achieve the same end. Filters that combine carbon and UV light, for example, are said to produce a better level of filtration than single barrier systems.

Traditional faucet filters vs. flavored water faucet filters

Traditional faucet filters attach directly to your water pipes and clean the water as it passes through. These are the most practical filters as they work only when you run the water as opposed to kettle filters that you must boil before you need the water.

Traditional filters don’t however always deal with the problem of bad smelling water. Most of us that suffer from this problem usually make sure the water is served cold to avoid the nasty smells and tastes. Flavored water filters can be used to add a flavor to the water to make it smell and taste better.

What should you consider when buying a water filtration system?


This might sound obvious but the price is an important part of your decision making progress. Sitting down and coming up with a budget before you begin your search is a really good idea. You will need to keep in mind that the cost of a filtration system is not just a one-time thing as the system will need filter changes regularly if you want to make sure that the water you are drinking remains pure. Filter price should be factored into your budget too.

How long the filter cartridge lasts

Most reputable brands will inform you as to how long the life expectancy of the system’s filter is. You can then get a rough estimate of how long it is going to last you before it needs to be replaced.

The USGS Water Science School estimates that a full grown adult will drink 8 oz of water per day.

To work out how long your filter will last, simply take the number of people in your family and times it by 8. This will give you a daily average that you can then divide the filters gallon lifetime by to see how long it will last. Most filters will last between 3 and 6 months on average.


Be sure when buying a faucet filter system online that you check the dimensions to make sure that it will fit under the sink or wherever else you wish to put it.

Flow Rate

It’s also worth making sure that the filter has an adequate flow rate. This information will be given on the products listing or on its packaging. Slow flow rates will make you wait for that glass of water frustratingly long and become a real annoyance over time.

Though not as easy to install as other designs on this list, it still is a design that can be installed without the need of uncommon tools. We would definitely only recommend someone who is familiar with a basic level of plumbing to install this, however.

The system uses a simple water divert switch that you can flip every time you want your water filtered. This is quite a standard design that saves on wasted filters as it only filters the water you need to be filtered.

Even so, the filters offer an impressive 200-gallon cleaning, meaning that most families will find themselves getting at least 4 to 5 months out of this system before needing to replace them. The filters are easily changed and don’t need any expert help or for you to even turn the mains water off.

PUR 3-Stage Horizontal Faucet Mount Chrome FM-9400B

PUR 3-Stage Horizontal Faucet Mount Chrome FM-9400B
This is another PUR filter that fits directly onto your kitchen tap to save you space. This model is available in chrome, stainless steel, black, white, and platinum and is an easy one click fit onto your tap design.

The main difference with this PUR system is that it is smaller, and though it offers the same 3 stage filtration system as its slightly more expensive brethren, it doesn’t quite achieve the same level of water purity. At 4 x 5 x 5 inches, this design will save on space at the expense of slightly lower water purity.

While the filters will give you around 3 months’ worth of top level filtration, you can expect them to last anywhere between 3 and 5 years before needing a replacement.

The reason why these 3 stage PUR filters are so popular and receive such good customer reviews is simple. They do such a great job at filtering all those unwanted chemicals pollutants out of your tap water without taking up nearly as much space as the more larger filter designs, and this one is no exception.

Brita Faucet Water Filter System with Light Indicator

Available in both chrome and white, this water system might look a little clunky but it is really effective at cleaning your tap water. Measuring in at 6.7 x 6.5 x 2.3 inches, it is a compact design that fits easily onto your tap.

Since most people these days tend to favor the facet design, we find they score a lot better on customer feedback. This one is no exception, being well loved by its users for its good level of water filtration and its relatively fast flow rate.

Designs that feature electronic filter replacement warnings are a real godsend as trying to remember when you last replaced a water filter is something that most of us can’t do. The filters in this design are easily replaceable and though not removing as many contaminates as other designs, this system still outclasses most of the competition.
