You’re here looking for the best water filter system. That could only mean you’re worried about what’s present in your drinking water as it’s no wonder: your water must make a long journey through the pipeline to get to your faucet.
Or, you just always smell chlorine whenever you take a sip from a tap (faucet), even after you boil the water…
… and you hate it.
Installing a water filter system is the solution.
But choosing a right filter system is not easy for everyone. This is especially true when you’re shopping online.
In this guide, you will learn about your drinking water. You’ll also learn what type of filter you want, and what price range you can afford.
In short, you will find the answer to your query:
“What is the best water filter system for me?“.
Let’s look at the different types of water filters, to decide which one is for you.
Whole House Water Filters
Filtering your water for home use is more a necessity than a choice nowadays if you care about your health.
It’s not only for drinking water but also for showering or washing clothes.
Water with contaminants can leave stains on clothes (especially whites) after a while.
Another way you can tell if your water has contaminants is by lather. If the lather from shampoo or soap disappears fast, your water may have contaminants.
That’s the reason why we have whole house water filter systems.
Who Will Need A Whole House Filter?
The answer is anyone, especially if your water is hard or sourced from a well.
Did you know that hard water destroys pipes and sewer systems over time?
Also, as we have seen, there are lots of other things to deal with besides hard water when your source is a well. There’s dirt, chlorine, pesticides, and sediments, and these too can cause problems.
The best thing to do is to decontaminate the water you use at home. In that way, you won’t have to put up with these complications.
There are whole house water filters designed for wells. They reduce iron, catch sediment, soften the water, and remove the sulfur smell. They also reduce the levels of bacteria growth, chlorine, pesticides, and herbicides.
A typical whole house water filter system removes 95-97% of VOCs and chlorine. It also removes sediment and other contaminants without wasting water.
Some of them do not reduce Total Dissolved Solids (TDS). But this point is not a significant factor.
The primary material inside a whole house water filter is charcoal. This material is also known as activated carbon.
These materials help cleanse water by capturing impurities.
The typical whole house water filter system costs more than an RO system.
You can find some under $200, but most of them go for more than $500. The prices even go into the thousands.
Most of the RO systems cost on average about $200 – $300.
Both standard whole house filter and RO will have long-term maintenance costs.
Of course, you must install the whole house filter system on the main pipeline. Once it’s connected, you will get filtered water from any faucet in your house.
You have two options for installing your whole house water filtration system. You can do it yourself or hire a professional.
People often have a plumber install their water treatment systems. They may also use an electrician to do the wiring.
Most of the filtration systems available online have step-by-step instructions. They are easy to install. You won’t need contractors with special training: a regular handyman plumber will do.
You should replace your whole house water filter cartridges every three months or
You can do it yourself.
First, turn the water supply off.
Next, relieve the water pressure on the lines before unscrewing the holder for the filter.
Remove the old filter and clean the inside of the holder with paper towels.
Put in the new one and screw the holder back in place.
Pros & Cons
The biggest pro of these filters is their health benefits. They filter out dangerous concentrations of sediments, chlorine, and chemicals.
The filters have a long life – five to ten years is typical. Whole house systems also need little or no maintenance. The filters last long and upkeep is negligible. Thus, a whole house filter is a cost-effective solution.
The disadvantage is that you cannot fine-tune your water filtration (Point-of-use filters allow you to take a more targeted approach. You can install these filters under sinks, in showers, or as freestanding units in the kitchen).
You might have to get a plumber to put in your whole house water filter. It requires more plumbing skills than installing a simple under-sink or countertop filter.
Under-Sink Water Filter
The under-sink variety can filter lots of water.
They deprive you of space from the cupboard underneath the sink, hence, they don’t clutter the counter.
You may have to drill a hole through the countertop or sink for the dispenser. You may also have to make other specialized plumbing adjustments.
You can use some inline filters for more than one appliance.
For example, you might be able to connect your filtration system to your fridge, water cooler, and kitchen tap. Inline filters are also an inexpensive option.
Most have quick-connect or push fittings that allow a seamless replacement process. They are also known for their durability.
On the downside, inline water filters are not reusable after the end of their service life. You will have to replace it in full when that time comes.
This replacement does not amount to high annual costs, given the durability and low cost of the filter.
Another con is that you must have some basic plumbing knowledge. Installing your inline water filter is technical, so you might have to hire a plumber if it’s too much for you.
Reverse Osmosis System (RO)
A reverse osmosis system is the best type of drinking water filter available.
These units produce pure, great-tasting water at a very reasonable cost. They remove solids like sodium, they also remove organic impurities, including chlorine and its byproducts.
They are automatic and trouble-free.
Reverse Osmosis Systems run on water pressure, not electricity.
What Is Reverse Osmosis?
Reverse osmosis occurs when water moves across a membrane. The water must run against the normal concentration gradient for RO to occur.
To illustrate, imagine a membrane separating fresh water from orange juice. With normal osmosis, the fresh water will cross the membrane to dilute the juice.
Reverse osmosis forces the water content from the juice to cross over to the freshwater side.
How Does A Reverse Osmosis System Work?
Most of the popular reverse osmos systems have five-stage filtration process, but some support up to 6 or 7 stages which adding back alkaline and pH to the water.
A normal reverse osmosis system works like below:
- Stage #1 removes rust and sediments.
- Stages #2 and #3 clear out chlorine and other volatile organic compounds present in the water.
- Stage #4 gets rid of bacteria, viruses, and other tiny particles and pollutants.
- Stage #5 removes any remaining odors and tastes from the purified water.
- Stages #6 and #7 (if applicable) sends the clean water through food-grade calcium carbonate to makes the water more alkaline and gives it a slight mineral taste.
How Much Does RO Cost?
You can pay as little as $70 for a reverse osmosis water filtration system. The better-quality brands cost a few hundred dollars (between $200 and $400).
How To Choose An RO Water Filter?
You’ve got a few crucial factors to consider when looking for the right reverse osmosis system.
Number of Stages
You will find most popular RO systems have 5 stages, but if you want your drinking water has more alkaline or pH, try a 6-stage or 7-stage system.
Normal or Full Contact?
With a normal RO system, you must open the housing to replace the membrane inside. It’s quite complicated, and you can make the housing dirty or cause it to leak.
A full contact RO system solves these problems.
Whenever you replace a stage (membrane), you replace the entire housing.
As you can see, a full contact RO system is much more convenient. But the maintenance cost will be higher, and it’s not very friendly to the environment.
How Many Gallons Per Day?
The makers of RO units state the amount of water they expect to produce in gallons per day (GPD).
There are 2 main factors affect the products are water temperature and water pressure. They also include the condition of pre-filters and total dissolved solids.
iSpring under sink reverse osmosis water filters are a great choice.
These filters deliver healthier, safer water. Whenever you open the faucet, you can experience safe, clean, good-tasting water.
The RO membrane eliminates harmful contaminants. However, it also removes a few essential minerals. That’s why iSpring has added a sixth stage in the RO process, to restore these minerals.

It can also work with your current tap, so you won’t have to drill a hole through your countertop. It removes chlorine, lead, and other particles.
Installation / Replacement
You can install your reverse osmosis system on either side of the sink. You can also place it underneath the sink, inside a cabinet, or in a basement.
Place the faucet on or near the sink where you get cooking and drinking water. Place the bladder tank where convenient, within ten feet of the tap. Most modern models feature easy filter replacement.
You can install the membrane once you connect the faucet to your plumbing system. Place the membrane into its housing according to the instructions provided. You may have to remove the housing cap and push the cylinder into the socket until it’s right inside.
The reverse osmosis booster pump increases water pressure going to the unit. The pump has three elements: a transformer, a pressure switch, and the pump itself. The transformer plugs into a standard wall outlet. The other components are easy to install.
The storage tank holds the purified water. Ensure that the space under your kitchen sink is adequate for the tank and the other components of the RO system. You’ll need to install a water line into the tank. You may need a plumber to help you with this step.
Advantages and Disadvantages
- Removes hard to filter elements such as arsenic, fluoride, bacteria, and viruses
- The under-sink option is great for renters.
- These systems are compact and easy to install, operate, and maintain.
- The water produced by RO systems is tasty.
- RO systems are abundant, and buyers have a variety of options from which to choose.
- The reverse osmosis process takes away most of the minerals from water. You can counter this with a six-stage filter, which remineralizes water.
- The purification process uses a lot of water. Your filter flushes about 4 gallons of water down the drain for every gallon it produces.
- RO systems take a long time to filter water.
- Reverse osmosis systems are quite costly.
Countertop Water Filter
Want a convenient source of high-quality water in the remote areas of your home?
A good countertop water filter can be your primary source of drinking water, even when you’re away from the kitchen.
Another use is as a portable filter for travel.
Several options are available, including the ubiquitous reverse osmosis type.
Electric Countertop Water Filter
An electric countertop water filtration system can convert regular tap water into alkaline drinking water. The filters come in stylish modern designs that will beautify any kitchen.
Countertop filters are easy to use: no installation required.
You can get BPA free options.

Non-electric countertop models hook up to your faucet. They deliver all the advantages of RO without the need for an electrical connection.
These systems are perfect for condos, apartments, and motorhomes. Students, seniors, and travelers benefit most from non-electric countertop water filter systems.
Faucet Mount Water Filter
As its name suggests, you mount this type of filter on your kitchen faucet.
The water first passes through a non-woven screen around the filter. This screen traps sediments like dirt and sand.
Next, the water passes through a compressed block of zeolite and carbon. These elements remove chemicals such as chlorine.
RO faucet filters use a combination of carbon and sediment to remove a wide range of pollutants.
Top Brands: Brita vs. Pur
Pur is superior to Brita when it comes to getting rid of sediments and chemicals.
Only Pur is guaranteed to remove cryptosporidium and giardia from the water.
According to Consumer Reports, people prefer the taste of Pur over Brita. They conducted blind tests, and most of the participants showed a preference for Pur.
One point on which Brita comes out on top is the speed with which its filters work.

Water Filter Dispenser
Water dispensers have become office staples, but they’re great for use at home too.
They’re a pro for the environment because their bottles are reusable.
They’re also attractive to look at and come in a variety of shapes, sizes, and materials. It’s easy to find a unit that’s the perfect fit for your space.
You also save money. Small disposable bottles are way more expensive than the large reusable ones.
Where To Use
A water dispenser can be useful almost anywhere. Some offices prefer them because they provide employees and clients with convenient access to water.
They are also common in homes where people do not have access to good drinking water from the tap, or for those who do not like the taste of tap water. Water dispensers can also be used in commercial settings.
You have several options if you’re looking for a home water dispenser.
One of the most common types is the bottled water cooler dispenser. You will need to place a 5-gallon bottle at the top of this dispenser.
If your space is tight, you can get a countertop water dispenser.
Another common type is the point-of-use dispenser. This dispenser does not need a bottle, because it has a continuous water supply.
For awake, healthy, less fatigued employees, it’s a good idea for offices to install a water dispenser.
Like home dispensers, there are several options from which to choose. These options include point of use, countertop, and bottled dispensers.
They are more sanitary than water fountains and are durable.
Besides, they are eco-friendly.
Also available are commercial-grade water dispensers.
These dispensers look like ordinary office water coolers but often come with filtration systems. Some keep the bottle design, but they dispense water much faster than the regular coolers.
Types Of Water Dispenser
Countertop / Tabletop
These water dispensers have small footprints and fit on a counter or tabletop.
The compact design is big enough to house a compressor to cool the water. Some models have only one spigot for cold water, while others have two. Some models need a bottle while others are of the point of use variety.
The advantage of countertop models is that they don’t take up valuable floor space.
Free-Standing water dispensers are a bit more expensive than countertop models.
They are a good option for spacious offices and homes.
You will need an electrical outlet for both types.
The water in a freestanding unit tends to get colder than that in a countertop model. It gets colder because the former has a larger compressor.
Hot & Cold
Most of the water dispensers on the market are hot and cold models.
The hot water is warm enough to make coffee or soup. That is why these appliances need an electrical outlet: to heat and cool the water.
Some models have a room temperature option. However, it’s easy to achieve room temperature water by mixing hot and cold together.
Bottled [Top load | Bottom Load]
Bottled dispensers are a convenient alternative to bottled water. You just have to flip the tab to access cold water.
They are also cheaper and eco-friendly.
The average person drinks 167 small bottles of water per year. Only 38 of these bottles will get recycled. The rest will end up in landfills.
Bottled dispensers reduce landfill waste. They also give you immediate access to cold, clean water.
Bottom loading water coolers tuck the water bottle out of sight. It stays in the cabinet under the cooler.
This type of cooler uses a pump to push the water up to the dispenser.
Some dispensers feature an empty bottle indicator that will light up when it’s time to change the bottle.
You can also buy one with a built-in nightlight that will make the water spouts visible in low light.
Bottleless [With Filter]
Bottleless water dispensers have even more advantages than their bottled counterparts.
Although the bottles are reusable, at some point they will reach the end of their useful lives.
Bottleless dispensers are better for the environment. Plus, you won’t have to strain to lift a heavy 5-gallon jug of water on to the machine!
Water Dispenser With Ice Maker
In-the-door ice and water dispensers are now almost standard on refrigerators. Side-by-side and bottom freezer models are most likely to have these dispensers.
You can also find countertop ice makers with a water dispenser that portable, you can either use them at home or camping.
It’s nice to press a lever and have your glass filled with cold water and fresh ice.
The water line on most dispensers run through a built-in filter. This filter should capture impurities like lead and mercury.
This filtration system should also improve the taste of your water.
Water coolers and dispensers come in different sizes.
Consider where you will place the dispenser. You also need to take the size of your household or office into account.
A five-gallon bottle might be too much if you live alone or if you have a small office. It might be better to get an 18-cup dispenser instead.
An 18-cup dispenser can fit in your fridge for quick, easy access to clean drinking water.
These dispensers contain filters to get rid of contaminants in your water.
This option is more affordable than bottled water and safer than drinking pure tap water.
3-Gallon / 5-Gallon
3-gallon and 5-gallon water dispensers come in countertop and freestanding models.
They occupy less than a square foot of space. Thus, you can place your cooler wherever it best serves your family or employees.
You can also put it in the customer area of your business.
They come in many different styles, so wherever you place your dispenser, it will fit your décor.
Small / Mini
Mini water coolers come in many different designs.
These coolers hold about 2.5 liters of water – equal to eight glasses.
They are great for personal use at home or in the office.
Some of the designs are appealing to children. For example, there are penguins, elephants, and TV characters like Hello Kitty.
The water in mini dispensers is at room temperature.
Large water dispensers are the most common option for offices. Many homeowners buy them as well.
These large coolers can be bottom loading, but most of them have a gravity feed with the bottle placed on top.
Large dispensers are also an excellent option for commercial use.
Plastic water dispensers are very common, especially in offices and commercial spaces.
It’s also common to see stainless steel.
Homeowners seem to prefer stainless steel because it goes well with their kitchen décor.
You can also find water dispensers made from materials such as glass and ceramics.
Plastic is by far the most prevalent material used for producing water dispensers.
Most people are familiar with white plastic dispensers, with a blue spigot for cold water and a red one for hot.
The plastic is durable and needs cleaning only about once per month.
Though white is standard, other colors are available.
Many point-of-use dispensers are made of stainless steel. This material has several advantages over plastic.
It goes better with the aesthetics of most spaces.
It’s also more durable than plastic.
The water is even better tasting, with no plasticky aftertaste.
Glass water dispensers are also available.
Caterers often use these dispensers. They are also becoming more popular in hotel lobbies.
This newfound popularity may be due to their aesthetic appeal.
Glass dispensers are an excellent option for upscale houses or apartments.
The idea behind ceramic water dispensers (or crocks, as they are also called) is centuries old.
People used ceramic goblets to keep their water cold in the nineteenth century. Even today, ceramic water dispensers are attractive alternatives to bottle coolers.
Finding countertop and freestanding ceramic water dispensers available for sale is not always easy, but worth the search.
Convenient 18-cup options like the Brita Ultramax are hard to beat. Brita water dispensers are perfect for offices, sports teams, and busy families.

- Pitchers take several minutes to filter your water
Refrigerator Water Filter
Setting up a good quality filter in your refrigerator is a cost-effective option. There is the extra advantage that your filtered water will be cold too.
A good fridge water filter will remove the impurities from your ice or water. It will also give you fresh tasting water dispensed straight from your fridge.
The lifespan of refrigerator water filters is also much longer than that of pitchers.
Personal Water Filter
Water treatment is essential to maintaining your health when backpacking, hiking or traveling.
When buying, you should know the difference between a water filter and a purifier.
Water filters strain out protozoans (such as Cryptosporidium) and bacteria (like E. coli). Water purifiers also fight viruses, which are too tiny for most filters to catch.
Filters are usually enough for backpacking or hiking. Purifiers are excellent for travel to less-developed parts of the world.
How To Find Your Best Water Filter
Know Your Water [The Fact]
We drink and cook with water from a kitchen sink faucet. But few people know about the type of water they are using.
Even fewer know what’s present in the water.
If you are using water from a well, you should know that it contains many elements such as metals and dissolved salts.
Their concentrations pose a health concern.
Geologists recently checked wells nationwide for two-dozen trace elements. They found trace elements in most of them.
Thirteen percent had one or more element surpassing federal health recommendations (Scientific American, 2011).
Water is soft as it leaves the heavens in the form of rain, which means it is free of contaminants.
But as it falls, it picks up impurities such as carbon dioxide in the air. It also dissolves magnesium salts and calcium as it penetrates through the earth. These elements remain as it runs off into lakes or rivers and gathers in wells or reservoirs.
The US Geological Survey calculates that 89.3 percent of homes have hard water (The Salt Institute, 2013).
The belt from Kansas and Texas to Southern California has the hardest water in the nation.
If you are living near the seaside and you are using water from a well, your water may contain salt.
Salt-water is corrosive, and it ruins appliances.
The taste of salt water is also undesirable, leading many to buy bottled water.
You can feel safe drinking tap water in most parts of the United States. However, some of it contains chemicals such as chlorine and pesticide residues.
Some states also have to contend with high levels of nitrates, lead, and arsenic.
And who can forget the water crisis in Flint, MI? Cost-cutting measures in 2014 led to the contamination of the city’s water supply (CNN, 2018).
The following video from Environmental Working Group (EWG) provides some numbers you should consider about:
Now you may have an idea about the type of water you are using and what you have in the water.
You may also be ready to install a water filter.
But keep reading.
You should know your needs and know about types of water filter before you can make a purchase…
… and we have all the info in short form right here.
Know Your Needs
You need to know your needs or how you will you use your water filter.
Do you want a commercial water filter system, or one for home use, or a personal-use water filter for hiking and traveling?
Commercial systems filter and disinfect water used by businesses and other large-scale operations.
Home use filters, as the name implies, are an excellent buy for homeowners. These filters improve the quality and taste of the water.
Personal use filters are for those who want to drink water from natural sources. These filters get rid of Cryptosporidium and other bacteria.
Commercial / Industrial Water Filters
Restaurants, buildings, and hotels often use commercial water filter systems. You can also find them in schools, hospitals, and factories.
A commercial water filter system can filter most contaminants. These systems filter large amounts of water to provide for many people.
The cost of a commercial filter system is prohibitive, but the result is worth it.
Usually, municipalities use this type of filter for well water or salt-water. Factories also use them to clean water for production.
Water Filters for Home Use
Most people buy a home use water filter because they care about the health and quality of life of their family.
Water filter and filtration technologies are growing fast. Thus, you will see many types of filtration systems on the market.
The water is of a much higher quality as the filter removes salt, iron, fluoride, chlorine, and bacteria. It also balances the pH levels and adds alkaline and flavor.
You can buy a whole house filter system, a countertop or under-sink model, or a dispenser. You can even get a pitcher with a filter within a reasonable price range.
You may ask: “What does a water filter system do?”
Let’s take a glance at the water filter functions before we go through all the type of home use filter one by one.
Water Filter For Personal Uses
Travelers and hikers may need a personal water filter when they explore new areas.
It’s a well-known fact that travelers should be wary of drinking from the faucet in some parts of the world.
Hikers also need to be careful, as water that looks pristine can sometimes contain bacteria that cause extreme gastrointestinal discomfort.
Personal water filters look like ordinary water bottles on the outside. They contain filters to purify water for drinking and cooking.
Functions of Water Filters
Water filters use two different methods to remove impurities.
Some use physical filtration and strain the water to remove larger particles.
The other process is chemical filtration. With this method, the water passes through an active material such as charcoal.
These systems must act as filters, softeners, and purifiers.
A water filter is a system that can remove most contaminants to provide a better quality of water.
Water softeners are a type of filter that softens water by removing or neutralizing minerals. These minerals cause scale and make water hard (known as hard water).
The filtration system treats hard water by using ion
exchange and salt resins. This process removes magnesium and calcium hardness.
Most of the water softeners are designed for whole house uses, not specific for under-sink or point-of-use.
There are 2 most popular types of water softeners: salt-based and salt-free.
Salt-Based Water Softeners
Salt-based water softeners remove minerals like magnesium & calcium to make your hard water “be soft”.
This type of water softener also reduces lime-scale in the water, limescale is a chalky off-white crust that stains on surfaces or lurks inside your kettle after a while of boiling water.
Using and maintaining a salt-based water softener will cost you a little bit more than most other water filters.
Salt-free Water Softeners
In fact, these options are known as water conditioners or descalers (Electric or magnetic water descalers), but they are called softeners even they don’t remove the water hardness.
With a salt-free softener, contaminants like magnesium and calcium will not be completely removed but neutralized to reduce the hardness in water.
You may spot limescale build-up from your water but Salt-free Water Softeners are the best options for people who don’t want to add sodium and other chemicals to their water.
Viruses are too minuscule for most filters to catch. Water purifiers fight these pathogens.
Like water filters, purifiers include an internal cartridge or element with microscopic pores. These pores grab bacteria, protozoa, and debris. They also use chemicals such as iodine to kill viruses, or distillation to separate water from contaminants.
There are many options to choose from, such as a pump, gravity, ultraviolet, and bottles. Each type has its pros and cons.
We’ve seen why water filtration is necessary for some areas, and how filters work.
These devices are friendlier to the environment than bottled water. Filtered water also tastes better, encouraging users to drink more.
When you think about the importance of hydration, it’s easy to see how the pros outweigh the cons.
Invest in a drinking water filter, and start seeing benefits right away.
