Buying Guides – How To Choose The Best Water Filter?

Water is one of those things that we cannot do without. The amount of water that we take in as well as the sources from which it’s obtained, can greatly affect our lives and health – for better or worse. This way you should care about not only your drinking water but also the water you use to clean your food and brush your teeth with. With so many products on sale today, made especially to assure us of safe and potable water, how would we know what exactly to choose? Here are some guidelines:

Brita On Tap Filter – Basic Faucet Water Filter

1. Types Of Water Filters

Whole-Home Systems – With this type of system, water can come from a number of sources – it could be the faucet or an external line – which is then forced up through a pressure tank and into your home’s plumbing. This one-stage filtration process reduces chlorine, organics, lead, cysts, and more. You can install this on an existing home or have it as a system.

Under-Sink  Systems – This water filter is a great choice for those who want to install the system themselves. It has all the features of a whole-home system yet is able to filter out any particles or contaminants from your drinking water as soon as it reaches the tap. This one-stage filtration process reduces chlorine, organics, lead, cysts, and more.

Countertop  Systems – This is the perfect option for those who don’t want to install a big system in their house. It isn’t as powerful as the first two options since it only filters out some of the contaminants but can still be considered as an affordable investment for your health and home’s plumbing systems.

Faucet Attachments – This filter attaches to the end of your faucet. It has a cartridge that should be replaced every few months then washed clean at least once a week. This type of system is not recommended for drinking water but is still sufficient in removing chlorine and other organic contaminants.

Pitchers And Jugs – Clear, colorless, and odorless, this type of jug is another great option if you don’t really have the need for a whole-home water filtration system. This kind of filter will remove chlorine, dirt, rust, or any other particles in your drinking water that may not be removed by traditional tap water.

Bottles With Carbon Filter – This is the type of bottle that you can carry around with you when you go out. It has a carbon filter inside to purify your water. The large ones are also able to store 2.5 pitchers of water for easier transportability.

2. Purpose Of Filtering Your Water

Are you only looking for a water filter that will improve your drinking water or are you wanting something that could also be used for cooking and other uses? The type of filtration system will depend on this purpose. If you’re just after the clear, clean flavor of filtered water then the countertop systems are always good for this. These types of systems work by filtering through a carbon block to remove chlorine and organic compounds from tap water. If you’re looking for something more advanced, then the under-sink water filter is your best choice since it is able to filter out much more than just your regular tap water.

3. Independent Certifications

Before buying a water filter, always check if it has been independently tested and certified. If you’re looking for a device that will purify your drinking water then the Water Quality Association (WQA) and NSF International (NSF) are 2 of the most recognized organizations for this purpose.

4. Capacity Of The Filter

The best thing about having your own filter is not just the assurance of getting clean water but also saving money by investing in a system that will last and work efficiently for a long time. If you plan on using your water filter regularly then it should be able to handle at least 100 gallons or up to 4 times more than what other water filters can do. If you’re just after a smaller option for your home or office then they can range from 5 gallons to 100 gallons.

5. Replacement Filters

Most manufacturers tend to sell their water filters in packages. The price of the system will vary but is usually cheaper than buying them separately. If you don’t want to hassle with the replacement filters then get a system that has a reminder indicator or alert when it’s time for a change.

6. Cost

The cost of water filter systems is different depending on the features it has, their capacity, and the number of contaminants that it can filter out. If you’re just after a simple yet efficient system for your drinking water then it’s best to go for one that costs less than $100.

7. Brands

APEC: This is a reputable brand that specializes in water filtration systems. They are one of the best when it comes to carbon block filters and produce some of the most efficient countertop water filter systems on the market today.

Brita: This is also considered one of the top brands for home water filtration systems. It has won several awards for its high-quality products.

PUR: PUR has an extensive range of water filtration and dispenser products for your home. Their faucet mounts are also one of the best sellers in this category since it has an impressive design that slides onto your current kitchen or bathroom faucet.

 8. Accessories

Pitcher Filters: These come with a built-in filter and can be placed directly into your refrigerator. They also have a handle to make it easy for you to remove the pitcher from its storage compartment.

UV Lens: This is an important component that helps purify water by killing viruses and bacteria that may accumulate in the cartridge.

9. Filtration Methods

Depending on the water filter that you choose, it is possible for them to have more than one filtration method. There are a few basic ones that may include:

  • Activated Carbon Filters: This can remove or reduce chlorine and bad odors from tap water.
  • Reverse Osmosis: Removes most contaminants but takes out beneficial minerals too.
  • Distillation: Removes contaminants but can be expensive to operate since it requires power.
  • Ultraviolet (UV) Filtration: This uses UV light to kill viruses and bacteria in water.

10. Water Quality And Contaminants

Depending on where you live, it’s best to check if your local water supply is safe. Start by checking the quality of your tap water. To do this, submerge a white towel or cloth into it then leave it for at least 12 hours. If after 12 hours there are signs of discoloration, you should consider getting a water filter.

The main contaminants that you should watch out for are:

Chlorine & Chloramines: These chemicals are used as a disinfectant to clean water from organic matter and parasites. If there is too much chlorine in your water then it will result in a bad odor and taste. It can also cause skin irritation or even exacerbate respiratory diseases.

Hardness: This can come from minerals in the water. It’s what causes your hair, skin, and clothes to feel rough or stiff after washing them.

Tannins: These are found in plants that leech into your water causing a brownish color.

Chlorine By-products: Some of these contaminants are created when chlorine interacts with other elements found in your water. They may lead to the development of diseases like cancer and kidney damage.

11. Filtration Rate

The number of contaminants that a water filter can remove will depend on the gallons per minute (GPM) flow rate. The higher this number, the better it is since it means that your purified water will be ready for use in less time.

12. Installation

Some countertop water filter systems only require you to attach the faucet directly onto your sink’s existing faucet. You can do this by screwing it or using a push-on connector. It may take around 15 minutes to complete this installation task if you have all the right tools in hand.

If you wish to replace your existing faucet then you will need to hire a plumber since it can be very dangerous otherwise.

13. Maintenance

You should never overlook the importance of cleaning your water filter. Cleaning it may seem like a tedious task but it will prolong its lifespan and improve its functionality.

You can do this by flushing out the system for 15 minutes at least once every two weeks. It’s also recommended to use de-calcifying tablets. Do not, though, use these tablets more than twice a month or it can break down the system’s components and clog the filter.

14. Flow Rate

The flow rate of a water filter indicates the speed at which it can provide purified water. First, check the gallons per minute (GPM) rating on your current faucet to get an idea about what you should be looking for when buying a new one. For example, if you have a low-flow showerhead at 2 GPM then you should find a filter system that has at least a 10 GPM flow rate.

Water filter systems are essential in any home or business especially if your current water source is not safe for drinking. There are many types of them out there that you can pick from but it’s best to read the most important things to know about them first.



What Is A Water Filter System? 

A water filter system is a device that removes pollutants and other undesirable substances like heavy metals, sediments, germs, odors, and even chlorine from drinking water. It does not replace or repair the water heater but can be attached to it for better performance.

Water filters are available in different forms, sizes, and styles so it would be helpful to know more about them before you choose one for your home. Remember this: quality increases with price usually so if you want an efficient product then expect to pay more for it. A simpler alternative is purchasing bottled water which is expensive too but at least you’ll know that what’s inside the bottle won’t hurt you since it has already passed through some rounds of filtration tests. 

There are four (4) types of water filtration systems:

Under-Sink System – this is a type of whole-home system that has an additional faucet and it has the same effect as drinking from a bottle. Because of its wide use, you can find them in most stores providing such services as installation, repair, and renewal.

Whole-Home System – this is like an under sink system but larger. It provides clean and safe drinking water to everyone inside your home with filtered lines going straight to all the taps (bathroom taps included).

Countertop System – this is also known as Point Of Use (POU) and it keeps countertops free from clutter since you only need to place the filter on top for dispensing. It is also easy to remove and it fits in most countertops.

Bottle-Style Water Filters (The Most Convenient)–  an alternative to owning a water filtration system at home is having the bottle version of such. These are portable and lightweight which you can purchase with or without dispensers then just fill them up before drinking time comes. Some of these bottles come with their own faucet attachments too so that you won’t have a hard time filling them up, especially when there’s no sink available nearby.

Do Water Filters Remove Bacteria?

Yes, water filters remove bacteria that may be present in the tank or line before it gets to your faucet. It takes out microorganisms that are invisible to the naked eye and drinks of this kind can cause flu, diarrhea, dysentery, and other stomach-related problems.

Can You Filter Any Type Of Water?

It depends on the kind of water filter that you are using. Some are for specific purposes only like filtering saltwater or pool water. There are even UV light filters that work best to eliminate cysts too.

How Long Do Water Filters Last? 

The life of water filters depends on how often it is used and the quality. It can last for three (3) months or six (6) months at most depending on the manufacturer plus you don’t have to replace it immediately but just keep an eye on its filter indicator light/gauge which lets you know if there’s a need to change your cartridge before using your faucet again.

Which Water Filters Remove The Most Contaminants?

The main water contaminants that can be eliminated through filtration are lead, mercury, and other heavy metals, pesticides, herbicides, chlorine, and others. The best systems both at home and bottle-type versions remove 99% of these parts per billion (PBB).

Do Water Filters Remove Fluoride?

Fluoride is a naturally occurring mineral that’s found in groundwater and it’s usually added to municipal water supplies to prevent dental cavities. There are also fluoride filters if you want to remove this substance from your drinking water so the best thing to do would be to check first if your home filtration system can help you with this.

What Should I Do When My Water Filter Is Not In Use?

When you are not using your water filter, it is best to store them in an upright position so that the sediment doesn’t settle at the bottom. Just make sure that you have dried all parts before doing this and if any indicator lights up when you try turning the machine on again, it means that there’s a problem with its cartridge.

How Do I Install A Water Filter: Step-By-Step Installation Instructions

There are simple steps that you can follow to install your water filter system.

Just make sure that everything is included in the package (follow manufacturer’s instructions) like hoses, screws, and fittings plus other necessary items for installation.

Turn off the valve underneath the sink where you will attach your new faucet then remove the old one if it’s still there by unscrewing its nuts or by turning counterclockwise then pulling out.

Check if there’s any pipe cement or water sealant at the connections of your old faucet as well as on the threads of the new equipment before putting them back together.

Screw-in a brand new washer then install it tightly with pliers once done cleaning up all rough edges from inside and outside of the sink.

Wash the hoses if included then screw in tightly on both ends of your new faucet with pliers or adjustable wrench.

Run an empty spot under the faucet for about 10 minutes to make sure that everything works properly before you fill it up with water.

Check if there are leaks or any drip issues after installation is complete plus do not tighten everything too much for now until you are certain there’s no weakness.

Avoid putting strain on these parts immediately by turning off taps slowly and avoid bumping them into anything hard since they can get scratched easily especially when you don’t have your new equipment yet or once you’ve finished installing it. You don’t want to see bits of plastic falling into the pot first thing after knowing that you’ve saved a huge amount of money, do you?

How Often Do I Have To Change The Water Filters?

There are different numbers of times you can use water filters before they need to be replaced. Based on some tests and recommendations, it is best to replace them yearly or after several thousand gallons but most manufacturers say that their water filtration systems could last up to three years especially if you use them all the time.

Does My Water Filter Remove Limescale?

Many kitchen water filters have been designed to remove limescale from water which is a good thing especially if you live in areas where the presence of lime or any other types of minerals can build up on your faucets and piping systems over time.

Just make sure that the filter you’re going to purchase has this feature included since it’s one of the most important things for those who use water purification systems at home as well as businesses like restaurants, coffee shops, and cafeterias.

What Do Water Filters Remove?

In general, water filters are made to remove all sorts of impurities from water which usually includes sediment or dirt that can get into your home if you do not have the right filtration system inside.

Some good examples would be cysts, bacteria, heavy metals, and other substances that could bring damage to your household including the growth of molds and mildews in areas where pipes are exposed with spaces behind sinks or underneath leaky faucet connections.

What Type Of Maintenance Is Needed For A Water Filter?

Water filters should not require a lot of maintenance. However, once in a while you’ll have to check the sediment from the water filter reservoirs as well as clean them up using vinegar or any type of household bleach.

In addition, make sure that your cartridges are still good and would last for several more months before replacing them as soon as possible especially if they become too dirty to use as expected.

Can You Use The Same Type Of Water Filter For The Whole House?

If you have a whole house filtration system installed then it’s possible but keep in mind that each household member may need one specifically for their own use unless there is only one shower and one faucet included in your home which means you’ll have to buy them in bulk.

This is what most people do to keep their costs low when they need to purify water especially if they’re living together in one house or apartment where the source of water supply is shared by everyone inside.

Are Water Filters Better Than Pitchers?

For everyday usage, water filter pitchers are the best choice since they’re made for home use. On the other hand, if you need something that can remove contaminants from the water instantly then whole house filtration systems are what you need to invest in.

Another option would be to purchase an under-the-sink water purification system which is usually offered by major brands like GE and Whirlpool among others.

How To Flush Your Water Filter: Step-By-Step Instructions

  1. Go to your water source and turn the knob clockwise all the way in to make sure that there is no pressure when the tap is turned on. This should remove any dirt or debris from your faucet head or kitchen sink sprayer if you prefer using one when you clean dishes.
  2. Using a pair of pliers, unscrew the aerator of your faucet so that it’s easier for you to reach inside with a rag or a cotton ball later on. Make sure not to lose any bits of rubber which might get inside so it’s best to have some tape nearby just in case they do fall off while cleaning them up before reassembling everything back together tightly.
  3. Check underneath your sink to see whether your water filter is still good or not. This can be done by looking at the color of the sediment or dirt inside which should be brownish if it’s clean, but if it looks like tiny pebbles then you should replace them as soon as possible.
  4. Take out the cartridge and make sure that you don’t lose any piece before washing it properly under running tap water for no longer than five minutes to remove any debris left within its nozzle using a toothbrush or anything else that works just fine for this purpose.
  5. Dump everything into the sink drain and then turn on the garbage disposal just to make sure that all particles are flushed down before turning off once more through powering off your faucet.
  6. After about five minutes, turn the water on to check whether it works or not by running cold tap water for a couple of minutes. If there are no leaks then everything is good but if there’s any type of leakage coming from the sink area where the faucet was installed then you need to tighten things up again using pliers or anything that can get rid of all loose metal bits including rust.
  7. Make sure that your cartridge is clean and dry before reassembling it back into its original position making use of pliers once more in order to attach it tightly. Sometimes, using pipe tape could be another alternative if you feel like it won’t come off easily at some point later on when you least expect it to.
  8. Listen carefully to see whether or not you can hear water running in your sink when the faucet is turned on just in case there are any leaks that need to be fixed right away.
  9. Now it’s time to test out your faucet by turning the knob clockwise again with one hand while trying to turn down your tap pressure by applying gentle pressure towards its main valve using your other hand so that no leaks will happen during the process of replacing the cartridge. Make sure that there is enough room for it especially if you have a top mount sink which means less space underneath already occupied by pipes, valves, and most importantly sealed off walls where they connect together at some point beneath this plumbing system where everything else takes place.
  10. Turn off the faucet and then turn on the garbage disposal to see whether or not it works properly before you go ahead and prepare some cold tap water for a glass of drink to check out if there are any leaks which is very unlikely at this point since everything is connected and secured properly with no loose parts floating around. That’s It! You’ve done it, congratulations!

How Do You Know When To Change Your Water Filters?

Water filters are a great way to ensure that the water you’re drinking is as clean as possible. This means not only removing any bad odors, tastes, and minerals from your tap water but also toxins that may have found their way into your home’s plumbing system from the environment around it which might take many years to build up since most of them won’t be visible without taking a closer look using a microscope at a water test conducted by professionals for this very reason.

If you want to save money, however, you can always know when it’s time to replace your filter cartridges by looking at its color first thing in the morning before going ahead and running your faucet for about 10 minutes or so letting it heat up together with the hot water in the tank itself in order to get a better sense of what it looks like under these conditions. If you see that the water is dirty then that’s a sign that it’s time for a replacement but if things look okay or they’re at least decent then you can just go ahead and continue using them until their flow rate starts to slow down considerably which should happen within about six months or so.

When it comes to testing your filter, start by drawing water into your glass once more making sure that there are no particles left behind after allowing some time for its flow pattern to settle down before adding any kind of liquid inside this container. Only use liquids such as tea, coffee, juice, or any other clear type of drink because opaque liquids may be too hard to see especially if you’re using brown-colored liquids to test out your water filter.

If this is the case then that means your filter needs replacement since it won’t be able to clear things out completely by letting particles remain behind inside your glass right away which could eventually make you sick at some point later on even though they might not show up immediately which isn’t something you’d want to happen at all under any circumstances. You can also put a drop of food coloring inside your glass after filling it up again with tap water in order to learn more about its performance over time just in case there are certain sections that aren’t working well enough anymore or maybe even because it’s already clogged and therefore less effective than before making this the only reason why you might want to replace them faster than usual.

The best way to do this would be either by using your hand or a cup which you can fill with water and test it out as quickly as possible so that you’ll know if it’s safe enough for drinking since things such as chlorine, algae, and even heavy metals such as lead may still remain inside after running hot water for several minutes letting these minerals provide sufficient time to dissolve completely without any issues whatsoever. Once your sink starts draining things will come together just right where they belong making sure that there is nothing left behind in order to ensure optimum performance and reliability especially when cooking food on the stovetop which means low maintenance hassles every single time.

How To Clean A Water Filter Pitcher?

Cleaning water filters are not very hard, especially when using kitchen products that can be purchased at your local hardware store. Once you’re done with them all, the next step would be to soak a clean rag inside a mixture of vinegar and warm water before rinsing everything off completely then drying it carefully making sure that no moisture remains behind before putting them back into their housing unit – these are typically plastic containers – where they’ll dry out fully overnight morning.

Taking this route will prevent you from having to buy new ones too soon since soaking wet things in vinegar might cause mold problems later on if you aren’t careful enough about how much time has been spent doing this which definitely isn’t something you’d want happening under any circumstances whatsoever since it could cause some trouble for you and your family down the road which is why it’s always best to follow these steps as closely as possible. This will also keep them from becoming scratchy and smelly because of dust particles that may be present inside certain containers once they’re put on racks or shelves in order to prevent this from happening just do a quick cleaning on them right away after taking things out of storage by using a delicate cloth or sponge made specifically for this purpose – storing fish tanks with no water isn’t recommended under any circumstances whatsoever since most fish tanks contain charcoal inside their filters which can make things very nasty smelling over time if not taken care of properly.

This will allow you to remove any type of dirt, bacteria, or other material that might be hiding on the inside of your filters which would only make it very difficult for you to enjoy using them properly especially if you can’t smell anything at all – this is a major indication of filthy looking units and definitely not OK – there’s more than enough time and opportunity here to fix these issues and make sure everything works as intended since most standard kitchen products that are used around the house can be just as effective by following some simple steps that might take an extra moment or two but will save you money in the long run as well as time whenever they’re needed.

What Is The Difference Between A Water Filter And Water Purifier? 

A lot of people mistake water filters with another similar device called ‘water purifier’. So what’s their difference? It may be confusing but both terms are often associated with each other since they’re almost exactly the same when it comes to their functionality, but there’s one major difference that sets them apart from each other which has to do with water contaminants.

Water purifiers feature heavy-duty filters that can remove any type of bacteria or chemical compounds in order for you and your family to feel safe about drinking water no matter where you are whether at home or outdoors. On the flip side, water filters use special cartridge materials which can trap small particles before they reach the bottom leaving only clean water available for everyone who might need it, especially during emergencies when boiled water is no longer available after a storm hits hard without warning.


We can definitely conclude that any household needs to use water filters no matter what. This is the cheapest way to make sure you and your entire family are safe at all times, especially when it comes to heavy contaminants like lead or particles which might be harmful to your children’s health since they’re more vulnerable than adults. If you want clean filtered water that won’t make you sick then it’s obvious that water filters are the way to go.
