Water is one of the most abundant resources that you will find in this world. You may have heard people say that water is life, which is not further from the truth. Research shows that a human can survive only up to three days without water. On the other hand, humans can survive 30-40 days without food (death can occur from the 45th day, as highlighted by hunger strikes in the past).

Dangers of using contaminated water

The human body is almost 60% water. Failure to take enough water, thus makes some of the organs to fail. However, water can also be a source of suffering, as documented in many studies. Some of the diseases that can be transmitted through contaminated water include cholera, polio, and typhoid.

Cholera deaths caused by drinking contaminated are about 485,000 every year. Research shows that 22% of healthcare facilities in the least developed countries do not have access to clean water. The same research shows that about 144 million people from different parts of the world rely on surface water.

How Water Bottle Filters Work

This is not a new concept. These bottles are fitted with a filtration system. It thus means that the bottle can be filled with water from different sources, and you rely on the filtration system to remove the contaminants and impurities.

These water bottles work in different ways, depending on the specific design. Some filters purify the water as it enters the bottle, while others filter it as it is consumed. However, all the different types of water filter bottles have the same goal; to purify the water.

Benefits of filtered water bottles

Environmental impact

We are living in a world where environmental degradation has become a hot debate for decades now. Water is supposed to be a cleaning agent and not a source for concern for environmental conservation. The typical water bottles come in single-use containers that increase plastics in our neighborhood. Refillable filtered bottles help preserve the environment and make the world a better place.


The modern world is very competitive and busy. The convenience to get water delivered right into your home is something that you can utilize if you seem to always be in a rush. One does not have to move from one store to the other looking for clean water for use. The assurance that the bottle has a cleaning system is all that one needs in this world where customer protection is still an issue.


The cost of living seems to be ever-rising. However, having access to clean water is not an afterthought but a basic need. Clean water is not that cheap and accessible, which explains how some end up consuming contaminated water. Filtered bottles help homeowners get access to clean water without breaking their banks. The initial investment that you make once you buy the filtered bottle is all that you need.

Factors to consider when selecting a filtered water bottle

Your needs

Do you want something for home use, or are you looking for a bottle that you can use while on the move? There are different types of bottles to suit different needs. A filtered bottle for home use should be big to cater to your family’s needs. On the other hand, a travel bottle should be something compact that can fit in your backpack and still keep you hydrated.

Types of filters

We have already mentioned that some bottles filter water as it enters the bottle. On the other hand, some filter when the water is being consumed. There are 4 different types of filters that you can find in a typical filtered water bottle:

The gravity filter. You must fill the reservoir with water, and then it will drip at its own pace. Such filters are somehow slow but allow the user to filter large volumes of water with minimal effort.

The straw filter. It is the most common type of filter you will find on travel bottles. The user sucks the water from the mouthpiece, and the filter purifies the water as it moves through the straw. Some of these straws are removable, and you can thus remove them when you have access to clean water. The downside of bottles with these types of filters is the energy required from the user to suck.

The pump filter. Bottles with such filters require varying amounts of effort based on the product. The water is safe for drinking once you have pumped it through the filters. However, you need to pump the water again after 48 hours elapses.

The squeeze filter. It is somehow similar to what happens with gravity filters. However, you are the one who will squeeze water through them, unlike what happens with the former. Some of these filters come with their own water bags that you can roll up and force the water through. However, if you find this feature missing, you can easily fit the filter on removable water bottles.


It is everyone’s dream to have a durable product. However, this does not always happen as manufacturers tend to have a product for every ‘class.’ You should answer the questions where and how to help you determine the quality that fits your needs.

Low-quality bottles are designed to soften the water. Such a bottle removes harmless bacteria and improves taste. However, the bottles will not protect you from viruses and bacteria that sip through.

Medium quality bottles are designed to remove some bacteria and particles. They are ideal if the water is from natural water sources such as rivers. However, it might not be a good option if human activities have contaminated the water source.

High-quality bottles are fitted with the best filters that will remove every foreign particle. You can bank on them to deal with bacteria, protozoa, and viruses.
