Buyer’s Guide: All You Need to Know About the Best Drinking Water Filter
Drinking water filter systems today promise to not just do away with strange odors and chemicals but also heavier chemicals like lead, mercury, and arsenic. They are also designed to do away with microorganisms like bacteria and protozoa and all other organic wastes that can enter your drinking water and unleash discomfort and diseases to your loved ones.
Most drinking water filter systems are either too costly or do not deliver on their promise of safe drinking water. Thankfully for our research, we have just the right amount of expertise to tell you what best drinking water filter you should put your money in.
In the most basic form, top-rated water filters either use three types of barriers:
To decontaminate the water that comes in your kitchen tap or anywhere there is that you drink water, trusting it to be safe and secure. There are as many ways of filtering drinking water as there are models of portable water filters.
Do Drinking Water Filters Work?
There are a plethora of drinking water filter systems on the market today, and you will see them everywhere – right from your close friend’s kitchen to your office pantry to the cafeteria that you frequent. It is a fallacy to think that all the water cleaning system is equal. There is no water filter for drinking that can claim to be one hundred percent. This is confirmed by Shiraz University of Medical Sciences research (The Effectiveness of Home Water Purification Systems on the Amount of Fluoride in Drinking Water). They cannot practically remove all the contaminants in the water how much ever they theoretically claim. It is not possible.
This is the reason why you should know the quality of the water that reaches your taps by conducting a water test with a third-party laboratory. Once you understand what the contaminants in your tap water are, you must start looking for a drinking water filtration system that fits your bill (and your budget).
The ball is, therefore, in your court! If you want to put your hard-earned money in the right place, make sure that you
Conduct a water test to determine the contaminants in your water before you head out to buy;
Read the label carefully to understand if the technology that you are investing in is something that will help you fix your drinking water needs.
Benefits Of Drinking Water Filter
It is essential to clean the water off chlorine that the water department adds to get rid of the bacteria and the protozoa that may reach your home with water.
Water filters improve the taste as well as the smell of the water.
Water filters also help in eliminating heavier and toxic metals that invariably find their way into water bodies by leaching or via effluent discharge from errant industries. More particularly lead, arsenic, and mercury that can take a toll on your loved one’s lives.
They give you freedom from packaged water and heaps of plastic bottles and cans that will invariably end up in landfills.
They are pocket friendly, and you do not incur recurring costs.
Drinking clean and filtered water protects you and your loved ones from diseases – both standard and some serious like cancers and other skin malignancies.
It is an affordable source of clean drinking water that you can use for cooking, brushing your teeth as well as watering your plants.
How Do Water Filters Work?
Water filters come in tens of sizes and configurations. They can remove:
Physical particles such as sediments, small rocks, and rust;
Chemicals such as chlorine, sulfur, and iron;
Heavy metals such as lead, mercury, and arsenic;
And microscopic organisms such as protozoa, bacteria, and viruses.
They use physical barriers to remove larger particles, and chemical filtration uses activated carbon to purify water.
There are four methods used:
Activated carbon filters.
Reverse Osmosis (RO) removes contaminants from water with the help of a semi-permeable membrane to trap Lead, Mercury, and Iron. However, chlorine and radon escape.
Ion Exchange filters soften tough water. The filter first off releases sodium ions that get exchanged with the heavy metal, and the result is that you get soft, more pleasing water in terms of taste. The only drawback is that it can drastically increase the sodium content in the water.
Steam Distillation heats water, and the cooling steam removes contamination. The steam then condenses and turns into water is thus purified. The only problem is that it may also remove some of the beneficial minerals from water.
Activated carbon filters are very popular. The porous block traps most of the contaminants. Large particles get stuck on the outside, and the chemicals get trapped internally.
How to Choose the Best Drinking Water Filter?
A filter that is about 4.4 by 20” is good enough to filter contaminated water. If it is the best under sink water filter, it should ideally fit inside the sink counter without jutting out.
Some of the contaminants that they filter are:
Nitrate as also perchlorate.
The flow rate largely depends on the pipe’s diameter. For instance, a pipe measuring ¾ of an inch can effectively have a flow rate of 13 to 14 gallons per minute; the bigger the diameter, the better the flow rate.
Filter life depends on the quality of water (the number of contaminants that the filter needs to eradicate) as well as the amount of water that is purifies measured in gallons.
Using water filters for home is not just great for your pocket; it is also very good for your immune system and overall health.
Ease Of Use
Thanks to technology, it is now possible to have access to the most healthy and safest drinking water on demand and the opening of a faucet.
Ease Of Install
All of the water purifying systems are easy to install. There are user manual, video tutorials, and helpful customer support executives will make installing it a breeze.
All the filtration systems come with a minimum one year guarantee. All the best brands have very responsive customer support to troubleshoot 24/7/365 in case there be a need.
A water purifying pitcher can be bought for as little as $50, and an under sink or countertop water purification system may cost you anywhere above $400.

Faucet Drinking Water Filter
Faucet drinking water filtration system is an inexpensive way of converting your normal tap water.
They are easy to install and extremely effective at removing all the menacing contaminants in tap water.
You do not have to change the cartridges as often as in other filtration systems.
They are eco-friendly because they do not produce any wastewater while filtering, nor do they need any form of energy to run.
It is estimated that they can improve the water quality by an impressive 20 percent.
They have cartridges filters that work to filter out contaminants from water. The first step of filtration is removing sediments from the water. It does this with a non-woven screen that is neatly wound around the cartridge.
The water reaches the activated block of carbon, where most of the contaminants get blocked in the high capacity filter mesh. Silver mesh added on the porous block of carbon will effectively kill microorganisms like fungi and virus.
The next stage is the removal of heavy metals and chemicals. The faucet water filtration system is slow compared to others because the more time water stays near the activated carbon block, the more capacity it will have to purify the water.
Faucet water filters take under five minutes to install, and there is no civil or plumbing work required at all; zilch! It effectively removes chlorine, which is a disinfectant used by the municipal water bodies. It removes all odors, tastes, and colors. And the best part is that you leave behind no carbon footprint because the plastic filter is completely recyclable!
Under Sink Drinking Water Filter
Under sink drinking, water filters are very efficient.
Except for RO system, most under sink filter do not waste any water while purifying.
They are not just efficient; they are also environmentally friendly.
It takes water from directly under the sink and purifies it in a plastic housing. Whenever you want to use the filtered water, you can simply open the faucet on the sink that is connected with the filter and enjoy contamination-free water anytime on demand.
The faucet from the filter does not interfere with your hot and cold faucet on the sink. It has its very convenient faucet.
Critics say that tap water may stay a very short time in the filter housing, and that is why the water may still contain contaminants, but this is not the case. The filter used is powerful enough to be able to retain all the chemicals, heavy metals, sediments, rust in the shortest time possible.
They are relatively easy to install, and changing the filter in some of the models is a breeze. The installation can be done by yourself only if you have minimum knowledge of plumbing.
Most models need a cartridge replacement in 6 months to one year, and some outstanding models may need it even once in 3 years, depending on the water quality and the amount of water filtered.
Best Drinking Water Filter FAQ
How To Install Water Filter?
Tools you will need
Home water filter;
Drain the system by turning off the water supply and then shutting the main water supply. Open all the faucets to drain all the remaining water in the pipeline.
Select the location that you want to install your water filtration system. Use the water filter template to mark its exact placement if this is your first DIY. Using a pipe cutter, cut the pipe length, you will need to use your bought best drinking water filter.
Protip: keep enough allowance beneath the tank of the filter for you to replace cartridges easily.
Make two cuts on the pipe and remove the section. Now tighten the cutter on the pipe in such a way that in lines up with the blade. Keep rotating the cutter till it cuts through the pipe and smoothens the burrs on the inside.
Now place the small side of the compression nut on one end of the cut pipe and slide on a ferrule. Repeat the same step on the other end of the pipe as well.
Choose a brass fitting thread and install the water in and water out port per the manufacturer’s manual. Use Teflon tape to seal the pipes. Take care, not to over tighten. Hold the filter on the set water line and tighten the compression nuts. Tighten all the fittings using a wrench.
Position and fix the water filter with the in port that is closest to the water meter and the outport closest to the water heater. Reversing this arrangement will mean that the water filter will not work correctly.
Check the installation for any leaks by turning on the filter valve. Change the settings to filter and let the waterfall inside the filter tank. Recheck the fittings for any leaks.

Should You Filter Tap Water?
In most parts of the US, tap water is safe to consume. Filtering tap water further removes any chemicals, heavy metals, or unwanted biological wastes and micro-organisms. Supporting your local public utility for drinking water is not just a smart choice but also a good for your wallet as well as for Mother Earth.
How Long Do Water Filters Last?
When you are buying a kitchen water filter, you may want to make sure if it comes with replaceable cartridges. It is a good idea to have spare cartridges at your disposal so that you can replace them without spending too much time. Some of the under sink drinking water filter comes with complimentary one or two filters.
If you are under counter drinking water filter comes with a sediment filter or sub-micron filter, you can replace the sediment filter two times in a year, and the sub-micron filter can be replaced once annually. Finally, it all depends on the kind of water and the concentration of a contaminant that is in the water that will determine how fast your filters clog, and you will need to replace them.
Do I Need To Clean Water Filter?
Yes, it does make a lot of sense to simply clean the filter rather than get it serviced once or twice a year or replace it once the need arises. However, cleaning the filter will big-time depend on what filter you are using.
UV purifiers/distillation units do not use filters at all, and that is why you will need to service the entire device whenever the need arises.
Filters that use activated carbon for removing impurities will reach saturation, after which they will begin to absorb some of the pollutants themselves, drastically reducing its filtration capacity. It is best to replace carbon filters once there is a build upon them and clogging.
Reverse osmosis filters are designed to dispose of the wastes automatically. Cleaning them once in two or three months will clear away the excessive build upon them, helping them to process the remaining.
Large and complex whole house water filtration system will need professional cleaning and maintenance. It is best to call in people to do it for you.
How Do I Know If I Need To Replace Drinking Water Filter?
If you have landed here, there is a high chance that you are also looking through drinking water filter comparison charts. If you already have a water filter system that you are looking to replace, here are the sure signs that you need to replace it:
Water filter manufacturers will generally give you a rough estimate of their lifetime. This is usually measured in terms of the number of gallons that has passed through the filter.
However, this is not the most accurate yardstick to discard your water filter and go in for a new one.
The overall condition of your filtered water. Use a testing kit to determine if it can filter out all the undesirable contaminants.
If you find your water very hard (difficult to create a lather with soap) and you suspect that there is a limescale build that is clogging it.
If your average usage of water has tremendously increased over a period and you find that the quality of filtration is compromised.
Significant decrease in water pressure.
When you notice a funky odor, taste, or color in the filtered water.
Does Drinking Water Filter Remove Bad Odor?
Are you experiencing a strong odor from your drinking water supply? It is highly recommended that you use the best drinking water filter for well water because of the rotten egg smell, maybe because of the breaking down of sulfur compounds by bacteria giving our very menacing gas called hydrogen sulfide.
Ultraviolet water filters can remove hydrogen sulfide or kill the Sulphur bacteria. They are also great for protecting your family from other microbes and heavy chemicals. There are two main filtration methods available for removing hydrogen sulfide from water:
Say the amount of sulfur is too high in your home drinking water, then the next and the best alternative to carbon is to use a filtration device that uses a media containing manganese dioxide. This compound occurs naturally and is usually employed to remove iron content from the water. It oxidizes iron effectively, and that is why it is marketed as an iron water filter.
Do Water Filters Remove Fluoride?
If fluoride in your drinking and washing water is the concern, thankfully, there is something that you can do to eliminate it. Go for the best countertop water filter that features RO (Reverse Osmosis) because water forced against the force of osmosis through the activated carbon mesh in RO filtration system is one of the best ways to make sure that fluoride does not enter your system either through drinking or other activities like showering.
Do your homework well before picking up a RO water filter.
Invest in testing kits to make sure that the water that is filtered through it is fluoride-free.
Keep extra meshes and cartridges at hand in case you find it not working well enough and as long as recommended by the manufacturer.
