  1. PFM400H filtration faucet mount – best for removing heavy pollutants

Made by the company PUR, it removes more than 60 contaminants from water, a record unmatched by their competitors. If you are wondering if this water filter is capable of removing heavy pollutants such as lead – yes it does. It even boasts records of removing lead levels of up to 99%, pesticide levels up to 92% and mercury levels of 96%. All of this is because the faucet filter uses the MAXION Filter technology that utilizes ion exchange and activated carbon filters to enhance purification and improve the water’s taste.

The cost is not prohibitive either – the closest machine that can purify water to this extent are reverse osmosis machines, which can get pricey. The water does not taste bad either because the active carbon filters improve the smell and taste of the water, and they reduce chlorine levels effectively as well.

It is very easy to install the system, and it fits perfectly on most kitchen faucets while saving space. If you have an awkwardly shaped sink, do not worry because the swivel head can turn 360o and enhances usability.

The system comes with an upgraded built-in monitor, while the battery life has also increases. The system has three lights that indicate different activities – when it is running at optimal status, when you need to change filters, and when the filter life over. The filters normally last for about three months or 100-gallons after use, though they will indicate to you when they are almost finished.


  • Removes over 60 contaminants from water
  • Has an electronic indicator that lets you know the filter status
  • Easy installation
  • The water has good taste after purification


  • It is not compatible with some faucet types

Why do you need a water filter system?

Cleaner water

Not all the water you get will be safe for drinking. The water filters are for this reason – they remove impurities from your water, leaving you with clean odorless water that you can consume.


Sometimes, discouragement from the poor quality of your water is easy that you resort to buying water. However, when you buy a water filter system, you get to save money in the end.

It is very convenient

You are more likely to drink purified water and use it on a daily basis, and get more amounts of this water at no extra cost.

You can choose when you want to filter

Most of the water purifiers on the market today come with switches that you can easily use to monitor when you want to filter your water – again, at no extra cost.


Types of purifying systems

Ultraviolet filter

Purification of water using UV rays is the safest option to kill microorganisms like viruses and bacteria, without sacrificing important minerals that are in the drinking water. It is an environmentally friendly method of water purification because it does not change the taste or add chemicals.

Activated carbon filters

These filters use the adsorption method of water purification. When water passes through them, the filter adsorbs harmful molecules that are present. You can use them as supplementary filtering systems along with UV radiation and RO purifying systems.

Reverse osmosis (RO)

These purifiers can filter out harmful impurities due to its semi-permeable membrane. The problem is, it also removes some essential minerals from the water and the water ends up with a flat taste. You can use it if the TDS of your water is above 600 ppm.

What is TDS – this is an acronym for Total Dissolved Solids, which comprises of small amounts of organic substances as well as inorganic salts. For safety purposes, you should drink water that has TDS levels of below 600 ppm. As a rule, groundwater contains higher TDS levels than surface water.

What you should know on water filters

It is important to understand what you want to purify in your water before going ahead to purchase them, because it is a commitment in itself. If there is heavy pollution of your water, then a filter will not be so effective. Here are several factors that you should think of when you want to purchase a filter.

What contaminants are you removing?

Filter designs are to remove specific pollutants. For assurance that a certain filter will remove a certain impurity, the package should indicate a NSF-certification.

NSF stands for the National Sanitation Foundation, and they are a non-profit testing laboratory that develop industry standards. Certified products have complied with the standards of the industry, and it works with third-party laboratories including WQA (Water Quality Assessment) and CSA (Canadian Standards Association).

For past tests, most reports focused on the removal of chloroform and lead, and you can use this as an indicator of how well the filter removes organic compounds.

You have to change the filters frequently

Filter systems all function using the same methods, with water passing through detachable cartridges that have filtering media, for example activated carbon. With time, the filters clog and lose their effectiveness, so this is the time you need to replace them.

Each manufacturer has differing guidelines on their replacement, so follow these instructions to get the most out of your filters. Some filters will come with light indicators to alert you that it is time to replace them, while others begin to filter at slower rates that tell you they are getting less effective.

Know your family drinking requirements

For two people, a carafe or two can be enough, but if your family consumes several gallons per day, then carafe types are too small. Also, factor in the water that you use for daily cooking because under sink and countertop models are capable of filtering large water amounts.

Some types filter water slower than others do

Think about your patience levels – reverse osmosis and carafe filters filter water at the slowest rates, so they have their own scale. Comparing countertop, faucet mount and under sink models, the faucet mount filters water at the slowest rates.

How to select a water filter

There are some guidelines to use when you want to purchase a water filter, and here are some of them.

What is your water source?

This is one of the most important questions to ask when selecting a filter. Does your water come from surface sources like lakes, ponds and rivers, or does it come from groundwater sources like boreholes?

If it is surface water from your local municipal corporation, then the TDS levels are low, so you can boil your water to kill microorganisms and it will be okay. However, if tankers supply the water, there are higher TDS levels that will change the taste of the water and affect your long-term health.

Most companies that sell water purifiers do simple TDS tests. Note that if water TDS levels are below 200 ppm, avoid Reverse osmosis – it strips the water of essential minerals and damages your health. Keep in mind that unnecessary use of purifiers is wastage of water resources.

The required pressure for the purifier

This is important because purifiers need pressure levels of between 5-40 pounds per square inch (PSI) to work properly. This may seem tricky to calculate, but you just see how many floors you live in from the water source. For every 10 feet upwards, you lose about 5 PSI, so if your home has low pressure, install a booster pump that will help to increase pressure, or use a UV purifier instead.

Where will the water purifier be located?

Purifiers need to be near water sources and electrical points with earthing. As a rule, let the distance between the electrical point/water source and the filter be within three feet.

It is also vital to keep the filter away from direct sunlight; otherwise, you can opt for a wall-mounted purifier, which takes up less space.

The filter power source

If you have frequent power outages in your area, choose a water purifier that has storage because the non-storage purifiers work entirely on stable electrical supply.

Storage options

If you get water for limited hours every day or every week, it is best to get a water purifier with storage. In this purifier type, your storage tank attaches to your purifier, which stores the water after the purification process. This is unlike other purifiers that need running water supplies.

Another thing to consider is the pollution of your storage tank. Even if you purchase the best storage filter out there, there are still some chances of contamination within your tank. Consider buying storage filters marked with ‘Bio guards’ that prevent this from occurring.

Your budget

It is important to consider the budget that you have and choose a purifier that contains all the important parameters. If your budget is very low, you can go for those that do a particular job.


For whatever water purifier you choose, you need to regularly change and service the components, and this depends on the water quality, this means that the poorer your water quality, the service needed will be frequent.

Wrap up

Based on all information on the filters, the clear winner is the DuPont WFFM350XBN. Because of its large capacity, certification from the WQA and its 4-year warranty, it is our pick for the best quality, and the water pressure selector ensures you filter the water at your own pace.
