Best Filters for Tap Water

Why should you consider water filters for tap water? Tap water is a convenient and affordable source of drinking water, especially compared to bottled water. But can you trust your tap water to be safe? How do you know whether it’s ok to drink tap water and when should you take precautions and install a water filter?

The quality and safety levels of tap water differ from region to region, since every region’s tap water is coming from different sources. For the most part, however, tap water in the United Kingdom is safe.

The water that’s treated at the source is not impervious to contamination as it travels through water pipes that may be old or unreliable. Thus, a good way to find out whether you need a water filter for your tap water is to get it tested.

Home water testing kits or laboratory analyses can reveal lots of information about the quality of your tap water including information about the presence of potentially dangerous chemicals or bacteria.

Signs you need a tap water filter

Even without submitting your tap water to a quality testing, there may be signs that indicate that you need to install a water filter for tap water.


Rusty pipes or tap water high in sediments can change your tap water’s appearance by making it cloudier or conferring it a rusty colour. If you notice any of these signs, at the very minimum, you may need a sediment filter to get rid of these issues.


If your tap water passes the appearance test, but it simply doesn’t taste good, then it’s time to find out what may be causing your tap water to taste bad. Your tap water may be high in chlorine or it may contain taste-altering contaminants.

Some water ingredients that may be responsible for altering the palatability of your tap water include: high mineral content, high chloride levels, high concentration of sulphates, presence of arsenic, lead or mercury, etc.


At times, you may notice that your tap water smells bad. This could be caused by high chlorine or chloramine levels, algae blooms, or presence of hydrogen sulphide.

While these signs may be good indicators that something is off with your tap water, the only way to know for sure what’s really causing these problems is to get your tap water tested.

Installing a water filter even if there aren’t major issues with your tap water may still be a good idea, since most residential water filters can improve the taste of your tap water and make it more palatable.

Where to install water filters for tap water?

If you do decide to invest in a water filter for your home, an important thing that you should consider is whether you want a point of entry (POE) or a point of use (POU) water filter. POE water filters, also known as whole house water filters, filter all the water that goes into your home, while POU water filters (countertop and under-sink water filters for tap water) are installed at a single point of use, usually your kitchen tap.

Depending on tap water usage and levels of contaminants in your water, you may choose to install a whole house or a kitchen water filter. Most homeowners will choose the latter, since they use the tap water from their kitchen not only for drinking, but for other purposes as well (washing fruits and vegetables, cooking, making coffee, etc.).
