Choosing the ideal filtered water bottle for prepping, survival, hiking or other outdoor activities can be quite the challenge when you are spoilt for choice. In this review we will cover which filtered water bottles are worth buying in our top ten list below.

Filtered water bottles can be incredibly useful in ensuring that the water you are drinking is filtered free of any potential contaminates and other harmful chemicals such as lead, fluoride and chlorine. They also aid in the removal of any microbiological and viral contaminants, making your drinking water much purer to consume.

Having the ability to drink from almost any natural water source regardless of the water quality is a wonderful benefit of using a filtered water bottle especially for preppers bugging out. You won’t want to leave the house without one. A filtered water bottle might just be the solution to a clean, drinkable water source that you’ve been looking for.

Things To Consider When Buying Water Filter Bottles


One thing to consider when buying a water filter bottle is what material it is made from. You will of course want your water bottle to be durable and have the ability to withstand the elements if you plan to take it outdoors, meaning that it will need to be of a high-quality material.

Ideally you will want to choose a BPA free water filter bottle, meaning it doesn’t contain Bisphenol A, which can be harmful to humans. Most bottles will have a 3 in 1 filtration system made from activated carbon, nano alumina and other various different filtration ingredients.


One of the main things to look out for when looking for a water filter bottle will be the price and what you can afford, as they can be much more expensive than just a regular bottle. The price may vary depending on the brand that you choose to purchase from.

Things such as what the filter bottle will be used for can also affect the price, for example the best water bottle with filter for backpacking may be less expensive than a filter bottle used for mountain climbing or one which has been specifically made for other extreme environments.

Prices can range from as low as £20 and go up to over £100, so be sure to choose one that suits your needs and budget.

You might think £40 is expensive for what is essentially a drinking bottle with a filter, but that bottle means you and your family can scoop up water from just about anywhere for months on end and know that it is safe to drink, saving you carrying or storing hundreds of litres of water. 


Before purchasing a water filter bottle, it is worth reading reviews on the choices you think you want to buy. Ask yourself how effective are these bottles at filtering water? Do they do an okay job or do reviews mention to stay clear and not bother purchasing?

You don’t want to purchase a filter bottle that doesn’t work as intended, especially in a life-or-death survival situation, as that would be a waste of money. Instead, narrow down your choices and do a quick google search on how effective they are at filtering water, it also helps to know what materials the filter is made from, as some are better than others.


You will want to consider the size and the weight of a filter bottle before buying one. You don’t want something that won’t hold the capacity of water you require, and you also don’t want something that is overly large and bulky as this can become challenging to carry.

For example, a filter water bottle with straw attached will be ever so slightly taller than one without when it comes to storing it in your bug out bag, but it does make drinking much easier, especially for the children or elderly people.

Ideally you will want a compact size that holds just enough until you can refill it again, a 500ml capacity is usually more than enough.
