Whatever your filtering water needs may be, there is a product available to suit your needs and it is worth the time investment to learn more about them in order to choose the best filtered water bottle for you.

Those in the market to purchase a filtered water bottle will be glad to know that they do not have to sacrifice style or convenience in order to find a great solution to meet their unique needs. There is no shortage of options available, and you are certain to find one to meet your personal preferences, needs, and budget.

As is the case with most products, all filtered water bottles are not created equal, and you could pay as little as a few dollars all the way up to fifty dollars or more.

Spending more does not necessarily mean better quality if you are paying for features you do not need.  For that reason, it pays to educate yourself on the main features filtered water bottles offer so that you can make an educated decision.

Follow along below as we help you navigate the world of filtered water bottles and clue you in on the most important features to consider.  We will also review our top seven choices to give you an idea of the range of quality and options available.

Important Features to Consider When Selecting A Filtered Water Bottle

Contaminant Filtering Ability

Basically, all types of water bottle filters are designed to filter out contaminants.  There are three main types of contaminants, and the most advanced water bottles feature the ability to filter out the greatest number and type of contaminants.

contaminant filtering ability

The types of contaminants include:

  • Chemical Contaminants: these are what you can expect to find in your tap water occurring naturally, as well as things that seep into water supply such as medicines and other chemical products.
  • Bacteria and Parasitic Contaminants: believe it or not, even the most highly filtered water has some of these things present, but many of them are not harmful and can be tolerated by us with no problem. However, there are several that can provide harmful health consequences.
  • Viruses: not to be confused with bacteria, these are much smaller and more difficult to filter out. Only the best and most expensive filters are likely to be capable to their small size.

Filtering Ability Pertaining to Water Source

The most expensive water bottle filters might be all wrong for you if you choose on that is ill-equipped to meet the needs of the source where you generally plan to collect your water.  If you are simply looking to make your tap water more palatable and better for you, the most basic of filter bottles should meet your needs just fine.

However, when you get into the really obscure water sources is when you really need to take a careful look at what your water bottle filter needs to be able to handle.

You would never want to use a lower end, lower cost water bottle filter on water from a source you are unsure of.  It might make the water taste slightly better, but your health is at stake and you do not want to take the chance of getting sick from bacteria or viruses.

In this case, you will really need to read up on the options available to you and purchase the best your money can buy in order to keep you safe and hydrated in extreme conditions.

It is generally not difficult to confuse those bottles which are designed for tap water with those designed for more varied sources.  Those designed for tap water will generally mention “sport,” on the go,” or “everyday” type of uses.  They may be able to handle those situations beautifully, but you would never want to risk using them for filtering water from a river or stream.

Filter Style

There are a lot of terms used in marketing filters, but when it comes down to it, there are two main types you can expect to find in a water bottle: carbon and UV.

  • Carbon: these filters are popular and used frequently because carbon is able to remove a wide range of contaminants as water passes through it. You will generally need to replace these types of filters often, and you generally see their filtering ability reported in microns (how fine of a particle it is able to filter).
  • UV: these are more expensive and use UV light to kill both bacteria and even viruses. However, they are not capable of removing chemical compounds. In some cases, you may even find a filter which features both carbon and UV in order to filter out all of the above.

Convenience Accessories

Thought not important with regards to the quality of the filtered water, convenience accessories such as easy-carry straps, quick-open and on-hand open lids, and other such accessories can actually be very important in terms of whether or not you will actually be equipped with your bottle when you need it.

Although they may seem like silly details, these kind of things can make all the difference in the world if they make it easier for you to carry the bottle among your gear or on your person.  You can also find a wide array of colors and designs to personalize your bottle to match your other accessories.

As mentioned above, you can see why it makes sense not to just purchase the most expensive filtering water bottle available and assume it will meet all your needs.  You would be throwing away your money if all you needed was a simple tap water filter but the one you ended up with also capable of filtering viruses and bacteria.

Now that we have shown you what to look for, we will go over some of our favorite choices available on the market today.

The silicone mouthpiece is made of food grade silicone, which makes it flexible and durable and can be removed for easy cleaning. Owners of this bottle seem to really love it for the fact that it enables them to always know that they will have access to clean drinking water, wherever their travels may take them.

Best use: International travel, worldwide outdoor use

Description: With a filtration system powerful enough to handle water from any body of water around the world, the Grayl Quest with Travel Purifier is also versatile enough for less rigorous uses as well.  Unlike other mechanical filters that filter water by pressing it through a fine screen, this style of filter works without any pumping, sucking, or other effort.

One uses it by simply filling the outer cup with water as indicated, and then carefully pressing the stainless steel inner cup down with even pressure until the orange purifier is on the bottom of the cup, and then the water is clean and suitable for drinking.

Although it is designed to only require gentle pressure, some users have found that it quickly becomes difficult to press after heavy use, and that filters do not last as long as indicated by the manufacturer.  The filters are replaceable, and the manufacturer suggests replacing once they become too difficult to press.  However, owners of this product rave about the water that comes out clean with no odor, color, or taste.

    Wow! all are great recommendations encompassing various kinds of lifestyle. I would like to add the Sawyer Mini, though not a top choice, but may still be a good mention. The Sawyer Mini Water Filter, on filtering, equals or does better than others with a .1 micron size. However, Sawyer was previously warned for its questionable claims for the product. Nonetheless, it is still a top choice for some filter water bottle users.

    • Bradley Page

      I think it’s better to stick to tried and trusted brands. Although Sawyer may be a good product, false advertising is troublesome. Remember that this is our health we are talking about so it’s good to be on the safe side. Stick to brands that are also truthful in their claims to avoid being sorry in the future.

    I plan to travel internationally soon and the Grayl Quest with Travel Purifier may be a good recommendation. It is like a water bottle you can take with you literally anywhere in the world. But I’m wondering if there might be a product which equals the quality of this product but can produce more than 16 ounces of water. It may not be the best option for people who need to consume water very frequently.

    • Bradley Page

      The LifeStraw Go Water Bottle is a good choice. I think it has all the qualities you are looking for in a travel purifier. In addition, this brand has been around for quite some time and has won many awards. The Brita Fill & Go Filtered Water Bottle is another great choice. There are other products that you can look into. The important thing is that you should a product that meets your needs and budget. I’m proud to say that the list above are all top-notch brands.
