1. Filtration System of Water Bottle

The heart of any filter bottle is the filtration process/system. Different systems or filtration stages work in a unique manner and eliminate particles, germs, and odor from the water. Let’s take a look at the filtration systems used in these bottles:

– Activated Carbon

The activated carbon, also known as activated charcoal is the most preferred way of removing substances from water. It is used by most of the companies.  

A bottle with black specks at the bottom has activated carbon filters. You can easily determine this characteristic.

As far as the life of this system is concerned, you are recommended to change it frequently, even if you can still see the black specks, especially if it is the only filtration source in a filtered bottle.

– Adsorption

Adsorption is the most important part of filtration. It concerns molecules, ions, and atoms attachment of a particular surface.

The activated carbon has increased number of binding sites. Therefore, it is simple to remove all kinds of harmful elements there in the water.

What makes this system very effective is the ionized carbon has highest number of binding sites among other chemical elements. This stage is effectively responsible for removing maximum germs and contaminants.

– Filtration

At last, the charcoal is able to suck all the contaminants in the water. It is understood that activated charcoal will be able to store the germs to a certain extent. That is why, you should replace it frequently.

2. Filter Capacity

The filter capacity is the amount of water a bottle can treat before calling it quit. The range of filter capacity varies from 25-gallons to 10,000-gallons.

Most of the manufacturers have declared the gallons of water a bottle can filter. The Sawyer Products SP140 has the highest filter capacity of 10,000-gallons. This product will serve you much longer than the others.

3. Capacity of Filtered Water Bottle

The next thing to consider while making a purchase is the overall capacity of the bottle. These bottles should have sufficient capacity but not too much that they add unnecessary heft.

Please note that joggers, hikers, or people on the go prefer filtered water bottles who have to refill the water from any nearby source.

Generally, the bottle capacity ranges from 15-ounce to 35-ounce and it should be selected based on your consumption needs.

If you need a high capacity bottle then go with the Sawyer Products SP140 will be the rightful selection with an overall capacity of 34-ounce.

4. Filtered Water Bottle Materials

The material plays an important role in determining product quality. Most of these models are available in plastic material since it is lightweight and fairly durable.

There is a large variety in plastic water bottles. However, your focus should be on BPA-free plastic that is non-toxic and does not impact the consumer’s health.

In the same context, you should also ensure that material is not too flimsy to not endure the wear and tear of outdoors. It shouldn’t bend or crack if somehow you have applied a bit extra force on it.

The Thermos TP4900SM6 is the most durable water bottle due to the stainless-steel construction. This model will walk miles with you. 

5. Is it Easy to Clean?

Cleaning is not at all challenging with filtered water bottles. Also, you should not worry about the filter because as soon as you remove the lid, the filter goes out.

You need a long brush, warm water, and soap to clean it. Just like any other plastic bottle, scrub the exterior gently. Also, try and rinse the interior with free-flowing water to eliminate soap properly.
