An Honest Review of the Grayl Water Filter

boy drinking from water bottle

About 60 percent of our bodies are made up of water, and it is recommended by health experts that we drink roughly eight 8-ounce glasses of water a day.

That’s a lot of water every day for optimal health, and in our efforts to be healthy, the last thing we want to do is consume harmful chemicals, metals, and or preservatives within all that water.

Now, add the importance of reducing our footprint of the plastic bottle pollution on the planet, and it becomes quite clear that a great water filter can make a huge impact. And we are going to focus on one very special water filter here, the Grayl Water Filter.

What Is a Grayl Water Filter?

GRAYL Ultralight Water Purifier [+ Filter] Bottle

The Grayl Water Filter is an innovative, brilliant, and life-changing product from the people over at Grayl.

It is a 16-ounce water bottle with two parts: the bottle itself, and a removable chamber that has a filter attached at the bottom. 

You fill the BPA-free bottle portion up to a certain point, slide the chamber tube back into the bottle, and through about 15 seconds of pressure, force the water to go through the attached water filter and into the chamber.

When the simple process is complete, and the chamber has slid all the way through the water in the bottle, you will have 99.99 percent purified and clean drinking water.

There are numerous water filters out there that use similar filtration methods to clean water, and we will get into those with more detail in a bit, but what makes the Grayl so unique is that it is one of the few transportable water filters. It is a water bottle.

So you can fit in on the side of your backpack or in your car’s cup holder. It has the power of purifying almost any water, anywhere!

Product Specs

Each Grayl Water Bottle comes with three pieces, which we touched on above. There is the main bottle, the inner chamber tube, and finally, the filter which attaches to the bottom of the inner chamber tube.

What is great is that after roughly 300 filtrations, you can purchase another filter attachment for much less, and get continuous use from your Grayl.

The Grayl comes in 4 cool colors: Black, Blue, Green, and Orange.

The filter removes 99.99 percent of all viruses from within the water and 99.99 percent of all disease-causing bacteria from within the water. The filter also clears sediment, chemicals (e.g., chlorine, benzene), and heavy metals (e.g., mercury, lead, arsenic).

You can be in the woods, see a stream, walk over to the stream, break out your Grayl Water Bottle, fill it with water from the random stream, push the filter through the bottle, and then hydrate right there, on the spot, as soon as thirst hits.

You will virtually never have to worry about dehydration again, as long as you can find freshwater sources around.

Filling your Grayl water filter up anywhere goes for out of the tap, too. You can be in any restaurant, anywhere, even on the side of the road in a foreign country, and fill your bottle with the water they have. The trusty Grayl water filter will clean, clear, and purify every drop of that H2O for your healthy consumption.

One of the other highlights of the Grayl water filter bottle is its quick-to-filter process. You have to rely a bit on some arm and hand strength to use the filtration of the bottle, but it is not too demanding of an effort.

When you finish filtering, you’ll notice that you have a roughly 16-ounce bottle of water and it has been merely 15 seconds. Most water filters, as we will see later on, take extended periods to filter adequately. Those machines rely on gravity, whereas the Grayl calls upon you.

Each filter of the Grayl displaces the use of 300 water bottles!

Each purchase contributes 1 percent of proceeds to environmental non-profits!

Ease of Use

The Grayl water filter is elementary to understand. However, it can become a bit difficult to push the inner chamber tube with the filter through the water. This minor difficulty doesn’t take away from the incredible experience of the Grayl, but it will reduce a star from its “Ease of Use” in our honest review.

  • MULTIPLE USES: Use great-tasting filtered water anywhere you use tap…

The Brita Stream Filter is an excellent option for an easy at-home water filter option. The filtration system has seen some advancement in recent years and is built in a way that you don’t have to wait for the water to go through the filter anymore.

You fill the pitcher up with tap water, and as you pour, it will move through the trustworthy and well-known Brita filter, resulting in a glass of clean and purified drinking water. It is as easy as that; all you have to do is make sure you change the filter after 40 gallons of filtration (about two months).

Ease of Use 

Our Grayl water filter review has found this Brita Stream Filter to be well designed. It is simple to use, but the weight of holding the pitcher as it filters slowly brings down the ease of use a bit.


Each filter lasts for up to 40 gallons of water filtration. And saves up to 1,800 standard water bottles a year!

Brita has taken on one of the most major issues with filtration systems, that it takes way too long to filter the water. Most people find themselves waiting 10 minutes or so to get their pitchers, dispensers, and bottles to fill with filtered water.

So it is exciting to think we won’t have to wait around any longer and we can rely on their new filter-as-you-pour technology.

However, many people complain about this new technology because it takes just as long to filter the water, except now the patience is due at pouring time. The filter takes a long time, and people with weaker wrists or arthritis issues can find a great deal of pain and frustration from the Brita Stream Filter.

Design Quality

The Brita looks modern, has a built-in filtration detection meter, which will tell you when to change your filter, and comes in 6 cool colors.


Brita offers a 30-day unconditional money-back guarantee if you are not happy with your purchase and a 90-day manufacturer’s warranty.

Soma Pitcher

Soma 10-Cup Water Filter Pitcher

  • New, improved filter reduces chlorine, mercury, copper and more
  • Holds 10 glasses (80oz) of fresh filtered water
  • Pitcher made of shatter-proof, BPA-free plastic

The Soma Pitcher is a very modern and clean looking water filter option. It is made up of 60 percent plant-based and renewable materials. Its filtration system is excellent at removing heavy metals and chemicals from water, most notably chlorine

When using it at home, one of the biggest worries about tap water is the chlorine content, so Soma truly comes to the rescue on that front.

Ease of Use

Our Grayl water filter review has found that the Soma Pitcher is extremely simple and intuitive to use. You just need to pour water in over the filtration system, and within a few minutes, you will have 10-cups of purified water to drink.

The only disadvantage, which lowers its ranking, is that many people find the wait time for the water to go through the filter and fill up the pitcher to be too long.


The Soma Pitcher removes chemicals and heavy metals fantastically. However, it doesn’t clear out potentially harmful bacteria and viruses. For those reasons, we have lowered its ranking.

Design Quality

The Soma Pitcher is one of the most aesthetically appealing water filtration pitchers on the market. It is also made out of 60 percent plant-based and renewable substances.


Soma offers a 1-year limited warranty for their pitcher.

The PUR Water Filtration Dispenser is fantastic because it uses certified filtration methods and holds up to 18 cups of filtered water.

The PUR Water Filtration Dispenser removes 96 percent of mercury from your water supply and significantly reduces the levels of chlorine, so you won’t get the odor or the taste as you work towards healthy hydration.

These are also certified for removing 22 contaminants from your water supply. And they provide filtration services for up to 40 gallons of water.

Ease of Use

The PUR Water Filtration Dispenser is simple in theory. You are supposed to just pour water into the filter, and it channels through to the dispenser. Many reviews have mentioned that this filtration system breaks easily, and moves the water through very slowly, making filling the pitcher up a lengthy process.


Again, many people have reviewed that their filters broke rather quickly, so considering that, our Grayl water filter review feels as though their ratings need to be brought down.

The filtration system is certified to work and uses natural coconut shells that have been steamed at extremely high temperatures to attract and snag harmful chemicals and heavy metals.

People have remarked that the heavily chlorinated water from their cities is significantly improved thanks to the PUR Water Filtration Dispenser.

PUR removes 99 percent of microbial cysts, 99 percent of lead, 96 percent of mercury, 96 percent of certain pollutants, and 92 percent of pesticides.

PUR also claims that no brand is certified to reduce more contaminants.

Design Quality

The PUR Dispenser is aesthetically designed with transparent plastic that shows two chambers. The first chamber is where you fill the water, and it is a cool royal blue. The second chamber is purely transparent and is where the purified water is stored.


PUR backs its dispenser with a 1-year limited warranty.
