Water is the most important element on the planet. We rely on it for so many things that compromising your water quality can have long effects on your health and happiness. Luckily for us, there are thousands of different systems on the market today that can effectively purify water.

Best Water Purifiers

Regardless of your budget, lifestyle, or space constraints, there will be a water purifier for you. Water purifier companies are engineering dozens of different styles of water purifiers that fit your personality and your lifestyle; you just need to know where to look!

In this guide, we will show you all the ins and outs of water purifiers. We will investigate the different types you can choose from, along with some key factors to look out for when searching for the best water purifier for you. Whether you are an adventurer trying to bring the water purifier with you or are simply looking to improve the quality of your drinking water at home, we have the know-how and guidance to find the water purifier for you.

How to Purify Well Water for Drinking

Well, water systems are one of the biggest headaches for water purifying professionals. They often have high levels of heavy metals, total dissolved solids, and viruses that make it very difficult to purify water and get the best water possible. When it comes to combatting iron and other well water contaminants, we now have a few different options to choose from.

Water for Drinking

Many companies are now focusing on handling well water with their products, and we are starting to see several good options. The best purification method for drinking well water is to find a filter that handles metals like rust and iron better than most.

This can be done with an under-sink filter or a faucet filter as well. Some self-filtering water bottles will be helpful as well, but you want to have as much available to you as possible when it comes to drinking water. I suggest investigating an under-sink filter specializing in heavy metals, the 3rd product on our review list is a great choice for removing many contaminants from your water supply.

If you are looking to have an on-the-go option, The GRAYL filtering water bottle or the LifeStraw Portable Gravity filter are great options. Both are adventurer or survivalist filters designed to turn even the grossest water supplies into healthy drinking water. If they can turn swamp water into healthy drinking water, they can turn your home water into quality purified water as well.

How to Choose Water Purifier for Your Home

What Water Purifying Style Do I Need?

As we begin searching for the best water purifier for you, we must first determine exactly what you are trying to get out of your water purifier. There are several different options to choose from, and once we have narrowed down the style, the more technical details come into play.

Drinking-Water

If you are looking to improve your drinking water at home for the entire family, you can do that with a quality self-filtering water pitcher. These are extremely affordable yet effective filters that are very common across houses all over the world. If you want to bring purified drinking water on the go, a self-filtering water bottle is a great choice as well.

These have the filters built-into the water bottle and will filter any water you put into the bottle. Keep in mind; if you are looking for more applications for your purified water than drinking water, a pitcher may not be the best option.

A whole-home system and many under-sink systems will provide you with quality drinking water, too. But if you are not planning on using any of the other benefits you get from these systems, then it is a large financial commitment for just one benefit you get from the system. One thing to remember with whole-home and under-sink systems is that they are more expensive, but you will not be limited to the amount of clean water you have access to. Water bottles and pitchers can only hold so much water.

Kitchen Uses (Cooking, Cleaning, and Drinking)

One of the most popular filter styles is the under-sink filter. It attaches easily to your existing cold-water line under your kitchen sink (or any sink) and results in an endless supply of purified water. You can use this water for anything you would like, and unlike static pitchers and water bottles, you will not have to worry about refilling the filter or be limited to a certain amount of water. Under-sink units will require more in-depth installations, but nearly all are designed to be installed by the homeowner.

A whole-home water purifier will provide you with clean kitchen sink water, too. It sends clean water to every single faucet in your home so that you can utilize the purified water anywhere. If you are not worried about your showers’ quality and sink water within your bathrooms, then a whole-home system is a large investment for those just wanting fresher water for cooking, cleaning, and drinking.

Purified Water For Everything

If you are looking for the best water experience throughout your entire home, then a whole-home water filter is the best choice for you. You will have a wide array of options that range from several hundred dollars all the way up into the thousands.

You will reap the benefits of healthy drinking, cooking, and cleaning water, along with the best showers you can ask for. The benefits of a whole-home system should not be ignored; you will have healthier hair, skin, and nails from your bathing water, which is invaluable over time.

My Water Quality

Once you have determined the best style of water purifier for you, you will now turn your attention to a device that fits you and your lifestyle the best. The first thing you must do is perform a water quality test. They are available worldwide and are cheap, affordable ways to know exactly what is in your water supply.

By performing a water quality test, you will know the exact toxins and amounts of those toxins that you are dealing with. Now, you can find the best filtration type and system that will remove your specific water contaminants.

Some filters are better than others at removing specific contaminants like lead and chlorine, while others can remove total dissolved solids and rusts better than others. The water test will point you in the right direction.

Filter Capacity & Water Usage

When it comes to saving money and keeping your system as maintenance-free as possible, you will want to investigate the filters’ life capacity. Some are designed to last for years, while others can last mere months.

The more you must change the filter, the more the dollar signs will add to replacement filter costs. Based on the number of people in your home and the amount of water you use, make sure to find a suitable filter that can handle a long enough time period where you are not constantly changing filters.

Another thing to look out for is water production capacity. Some filters have a maximum amount of water that they can purify in a day. For example, if you are looking into a water distiller, make sure you know the amount of water it can produce each day. Many are capped at just a few gallons, which is plenty for some people and not enough for many others.

Meets NSF/ANSI Standards?

Be on the lookout for products that are certified by NSF/ANSI. These are proven to be quality products that are independently tested. The NSF is a 3rd-party testing company that will thoroughly test products like water filters and purifiers to ensure that they receive a quality product.

The NSF has different standards for different qualities within a filter or softening system. For example, if a product is labeled as NSF certified for standard 42, this means that the NSF has tested and proven that the product can remove chlorine effectively. The more certifications and standards a system has, the more peace of mind you should have about buying it.

Flow Rate & Water Pressure

Many people worry that a water purifying system will slow their flow rates and water down. Years ago, this was the case, but as technology has evolved, so has the purifying world. There are a few things to ensure when selecting the best water purifier. Flow rates will still fluctuate, and if you are choosing a whole-home purifier, make sure you get one that can handle the number of faucets and bathrooms in the home.

When it comes to under-sink systems, they will also have different flow rates. Many will be above 0.5 gallons-per-minute, and this is a nice and steady rate. If you see something lower than that, you may want to consider going in another direction.

Installation & Maintenance

Many people are turned off by the idea of installing any sort of plumbing device, and if this is a worry for you, do not worry; we have a solution for you. Water bottles, water pitchers, and straws require virtually no installation or maintenance. Just pop the filter in, and you are good to go! But it is when we get to the other systems where installation typically becomes a worry.

Under-sink units do require a little bit of plumbing. You do not need any prior experience, though! Nearly all these systems are now designed with the homeowner in mind, and they are doing everything they can to remove any additional installation costs. Lookout for any systems that have online instructional videos and 24/7 support. These are great tools when installing an under-sink water purifier.

Whole-home systems require the most installation, but they are still straightforward for a lot of people. This will require some more heavy lifting because they usually involve tanks and other larger equipment, but it can be done with ease with another set of hands. One thing to be aware of is warranty rules when it comes to installation. Some companies are sneaky and will advertise that the system is self-install, but they will not tell you that if a licensed plumber does not install the system, it voids the warranty.

Warranty

You should always investigate the warranty policy of any system you buy. When it comes to water purification, they are typically perfect. With pitchers, bottles, and other mobile filters, they will usually have a minimum of a 1-year warranty. This is standard and covers nearly everything.

When it comes to whole-home systems and under-sink systems, you want to take a look at the fine print. Some will advertise a 5-year or even lifetime warranty but ensure that this covers the entire machine and not just the valves. This is a widespread practice with these systems. Ensure the device you choose has a warranty that covers all aspects of the system.

1. Aquagear Water Filter Pitcher – Fluoride, Lead Filter

Aquagear Water Filter Pitcher

The most economical way to get clean drinking water is a water filtering pitcher. A few years ago, there are few options, but now thanks to Aquagear, we have another filtering pitcher! I love that these pitchers are so simple and easy. Just pop the filter into place, fill it up and let gravity (and the filter do their thing)

Aquagear prides themselves on their filters ability to remove over 2000% more contaminants than its competition.

Combining these facts, along with the company’s overall mission of a more sustainable planet, makes this Aquagear filtering pitcher a great option. Small enough to hide in the corner of the fridge unnoticed, this water filtering pitcher does not take up space but still holds enough water to keep you hydrated all day.

Additional Specification

  • Best For: Heath & Sustainability
  • Color: Clear
  • Brand Name: Aquagear
  • Item Weight: 3.02 pounds
  • Flow Rate: 15-20 Minutes for 8 Cups

Why We Love It

  • The filter is small enough to easily fit into the refrigerator without taking up a lot of space.
  • The installation of the filters was fast and simple.
  • Water testing showed that after filtration, fluoride and other trace elements were greatly reduced.
  • The filter life is MUCH longer than other water pitches that are like the Aquagear.

Keep In Mind

After a few weeks, the filter takes a very long time to complete the process.


2. HQUA-OWS-12 Ultraviolet Water Purifier Sterilizer Filter

HQUA-OWS-12

If you are looking to take your whole house water supply to the next level, this UV light sterilizer will bring you there. Designed to work best with another water filtration system, this sterilizer will remove anything that finds its way through the filtering process.

There is virtually no additional maintenance with this sterilizer, which provides homeowners with peace of mind.

Bacteria and microbes are difficult for many water filters to remove, but it is proven that a UV light filter and sterilizer can remove that pesky bacterium. The power chord is over 3 feet long, making it easy to fit into any space.

The smart controller will allow the homeowner to have full visibility of their system status and lets you know with a loud beep when there is a fault.

Additional Specification

  • There is an LED light that allows you to know the system’s status and ensures all is working correctly.
  • There is very little maintenance with this sterilizer. The quartz sleeve needs to be cleaned a few times per year and replaced every two years.

Keep In Mind

To get the most out of the sterilizer, there are many requirements that the water must obtain that require a separate filter.


3. Woder WD-S-8K-DC Water Filtration System – WQA Certified

Woder WD-S-8K-DC

One of my favorite things about this filter is that the faucet’s flow rate is not affected at all! That trait alone is worth its weight in gold for me. The Wonder under-sink filtering system is a small, sleek system that fits under your sink without taking away any precious storage space. Installation was simple, and filter changes will not provide any headaches down the road either.

Combine the system’s simplicity with the fact that it is a WQA certified system for lead removal, and you have the total package! We trust the WQA, but since we run independent testing, we had to check the lead levels ourselves. Sure enough, there was a noticeable reduction in the lead, other heavy metals, and chlorine.

Additional Specification

  • Best For: Longest Life
  • Color: White
  • Brand Name: Woder
  • Item Weight: 2.82 Pounds
  • Flow Rate: ‎2 Gallons Per Minute

  • The Wonder model claims to remove harmful contaminants but leaves healthy minerals, and according to my water testing, this was true.
  • The small size was easy to install under the sink and is not noticeable at all.
  • Water testing revealed a decrease in several different water-based contaminants, including lead!

Keep In Mind

  • It does not work well with water supplies that are coming from a well.
  • It is not as effective on warm water; water should be cold to see the best effect.

4. Engdenton Faucet Water Purifier Reduce Chlorine

Engdenton Faucet

The first thing I noticed about this faucet filter was the quality of the materials. It is constructed entirely of stainless steel and looks great in your kitchen.

When it comes to performance, the 320-gallon filter life is near the top of the spectrum regarding filtering longevity. The activated carbon filter is a nice feature. It is there to inhibit bacteria growth around the filter and remove metals and sediments from your water supply.

Another feature that I liked was the 360-degree rotating faucet head that you can move with ease. It makes it easy to clean any dish you need, or my favorite part, fill a large water bottle that would not fit underneath it otherwise. There is a lot to like about the Engdenton filter; it does a great job of removing the water’s toxins and looks good doing it.

Additional Specification

  • Best For: Home
  • Color: Silver
  • Brand Name: Engdenton
  • Item Weight: 1.48 pounds
  • Flow Rate: ‎3 Liters Per Minute

Why We Love It

  • Tastes and odors associated with chlorine are removed from the water.
  • The filter can rotate 360 degrees for help with cleaning, drinking, and anything else.

There is a lack of information from the company about specific contaminants that this filter removes. I wish they provided more.


5. Brita Ultra Max Filtering Dispenser

Brita Ultra Max

Brita is a worldwide leader in water purifiers, and this in-refrigerator model is exactly why. The first thing you notice is the water capacity it can hold. This is the perfect solution for large families that go through a lot of drinking water every day. The spigot at the bottom is solid and does not leak, which is a huge concern with spigots on water tanks.

The filtering quality is what you would expect from a Brita device. It excels at removing those pesky tap water contaminants like chlorine and lead. If your city water supply is high in chlorine and fluoride, this may be the water purifier for you. Refilling this filter is a breeze, thanks to the flip-top lid that is simple to open and close.

6. BWT Premium Water Filter Pitcher & 3 Filters

WT Premium

Coming in 6 unique colors, the BWT Premium pitcher looks great while it is turning your water into crisp, clean water. This pitcher is different than most.

Usually, you will find a single filter in most pitchers, but the BWT has three separate filters to ensure no bacteria or lead is sneaking through and into your drinking water. There is an additional magnesium filter that adds valuable elements to your water, making it even healthier.

The pitcher is made from a strong and durable plastic that you would have to try and break. The handle is perfectly shaped, and it is by far the most comfortable water purifier pitcher handle we have tested to this date.

The design is also nice because it is skinny enough to fit in your refrigerator with no problems. The filters will last up 1-month with heavy use, but we have been able to get nearly eight weeks out of them!

Additional Specification

  • Best For: Families
  • Color: Arctic White
  • Brand Name: BWT
  • Item Weight: 2.2 Pounds
  • Capacity: ‎40 gallons

Why We Love It

  • The handle is nice; it is ergonomically the best handle we have seen thus far.

  • The three filters do a great job of removing lead and chlorine.
  • It does not take up a lot of space in your refrigerator. It has a sleek design.

Keep In Mind

7. GRAYL Ultralight Water Purifier [+ Filter] Bottle

GRAYL Ultralight Water Purifier

GRAYL has changed the game with its simple push-button filtering design. In a mere 15 seconds, you can filter 16 ounces of water for drinking or cooking quickly. Using virtually any water source on the planet, this GRAYL model is considered by many to be the best self-filtering water bottle on the market.

There are so many different places that this portable water filter bottle can come in handy. Whether it is the mountain creeks, fly-fishing streams, or rainforest pools, the GRAYL water filtering bottle can remove up to 99.99% of viruses, bacteria, and protozoan cysts. It will also remove sediment and heavy metals from the water supply, a sporadic feature for a self-filtering water bottle.

If you are a traveler and spend time on airplanes, this is a great option for you. Every year, travelers throw away millions of plastic water bottles. With the GRAYL self-filtering water bottle, you get the equivalent of 300 single user water bottles. The 3-stage filter lasts for about 40 gallons and is easily replaceable.

8. New Wave Enviro 10 Stage Plus Water Filter System

New Wave Enviro

We love simple water filtration systems, and the New Wave system checks that box. It was a breeze to install, and the water faucet diverter that is included seems solid, and I do not see any leaks coming from it. It is hard to ignore the fact that the water will run through 10 unique stages of filtration. That is a high number for a countertop system, and that cannot be ignored.

Any water system with certifications from both NSF/ANSI and the Gold Seal Association can be trusted to provide you with a safe and reliable recommendation. Filter changes are easy with the New Wave system, and the long-lasting filter life of 1,500 gallons saves you money in new filters in the long run.

9. CO-Z 110V Brushed Stainless Steel Water Distiller

CO-Z 110V Brushed

The health benefits of drinking distilled water are well documented. Research shows that you are helping your blood transport oxygen and nutrients throughout the body by drinking distilled water. If you are looking to reap these distilled water benefits and save money on water in the long run, then you will want to investigate this system.

Water distillers are notoriously slow; some can take up to 8 hours to produce 1 gallon of purified water. The CO-Z distiller is one of the faster ones on the market, but you are not sacrificing any water quality because of that fact. By combining the heating elements of the distilling process with an activated carbon stage’s filtering capability, you are getting the best of both worlds with this system.

Keep In Mind

  • The installation and set-up manual were very unclear and lacked detail.

10. LifeStraw Portable Gravity Powered Water Purifier

LifeStraw Portable

They are designed to be used in survival situations or have no other source for clean water than that dirty river flowing through the mountains.

Frequently Asked Questions and Answered

Does purified water have fluoride?

By definition, purified water does not necessarily mean it has minerals or not. When we refer to purified water, we state that the specific water supply is free from harmful contaminants. But luckily for us, almost all water purifying solutions will leave the good minerals, and some systems will even add them back into the water supply in larger amounts.

Can I use purified water in my CPAP machine?

You certainly can do that if you wish. But is most common to use distilled water for CPAP and other sleep apnea machines. Distilled water has qualities that will oxygenize blood and therefore oxygenize the body.
