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.
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.
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.
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.
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.
Best water purifier Reviews
1. Aquagear Water Filter Pitcher – Fluoride, Lead Filter
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.

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

- Flow Rate: 2 Gallons Per Minute

Keep In Mind

4. Engdenton Faucet Water Purifier Reduce Chlorine
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.

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.

6. BWT Premium Water Filter Pitcher & 3 Filters
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.

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.

Water distillers are notoriously slow; some can take up to 8 hours to produce 1 gallon of purified water.

You certainly can do that if you wish. But is most common to use distilled water for CPAP and other sleep apnea machines.
