Features to consider when selecting a water bottle with a filter

When buying a water bottle with a filter, it is important to know a few things about the filter, as this is the main reason you’re getting the product.

Filtering Ability

Basically, all types of water bottle filters are designed to remove various contaminants. There are three main types of contaminants, and the most advanced filters have the ability to purify the majority of them. Next, let’s learn more about these contaminants, and we’ll also see why is it important to reduce them as much as possible from our water.

Filtering ability

Chemical Contaminants

These are what you can expect to find in your tap water. The most common unwanted elements are chlorine and fluoride. The former one gives the water a specific and unwanted taste, while the later has been discovered to cause various health problems.

Some filters are able to reduce up to 99.99% of these 2 chemicals. This is a good feature to consider if your area is known to have contaminated tap water you might not want to drink.

Bacteria and Parasites

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.

Water source


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. While bacteria and parasites can be found in all the waters out there, viruses are more likely to be found in water directly taken from rivers or lakes.

Most of the times when camping or hiking, people rely on these water sources to quench their thirst, cook, or wash themselves. Drinking this unfiltered water is the most dangerous, but can be avoided with an appropriate device.

Filtering Ability Pertaining To Water Source

The most expensive filters might be wrong for you if you choose one that is not equipped to treat the water you’re collecting. If you are simply looking to make your tap water more palatable and better for you, the most basic filter should do the job just fine.

Filter type

When you go to obscure water sources, you have to be more careful with what your bottle’s filter is able to handle. You would never want to use a lower end filter on water from a source you are unsure of. In this case, the filter might make the water taste and look better, but your health will still be at risk.

It is relatively easy to confuse the products designed for tap water with those created for more varied sources. The former will generally mention “sport,” “on the go,” or “everyday” in their descriptions or names. The others will also be adequately labeled.

Filter Type

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.

Useful filtered water bottle


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 quite often. You generally see their filtering ability reported in microns, representing the smallest strained particle.


These filters 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 that features both carbon and UV in order to filter out all types of contaminants.

Available Accessories

Thought not important with regards to the quality of the filtered water, convenient accessories such as easy carry straps, quick open or one hand open lids can be important. These features could make all the difference when you want to easily access your bottle and have one busy hand. You can also find a wide array of colors and designs to personalize your bottle.

What’s more, you want to make sure you’ll be able to find extra straws, lids or filters. This aspect seems small even to seasoned backpackers used to certain brands, but not all manufacturers offer the same options for their products,a s you’ll see below.

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

However, owners of this product rave about the water that comes out clean with no odor, color, or taste.
