Factors to consider while buying a portable water filter

Below are a few factors which you should consider while buying a portable water filter

Filtration Efficiency

One of the essential factors to consider. Since the filter would be used on the go with water from different sources, the water is bound to have multiple types of sediments, harmful constituents, bacteria, protozoa, etc.

This makes it very necessary to make sure that the portable filter efficiently filters all harmful constituents from the water, thereby giving you fresh & pure water.

Ease of Use

An ideal portable filter should filter water on the go quickly without involving too much hassle in setting it up & using the same. While there are multiple models of portable filters available in the market, not all of them are easy to use.

Many portable filters are available as a multi-component package which needs to be assembled every time you need to use it. It is better to avoid such filters and instead go for easy to use single piece efficient portable filters.


The whole aim of using a portable water filter is to get pure filtered water on the go. So lookout for a small & compact portable water filter.

There are many affordable options available which weigh less than 20 oz- some of which are mentioned above. Do not go for large, odd-sized portable filters since it would defy the whole purpose of using a portable on the go water filter.


Pricing should also be considered. Almost all of the best portable filters available in the market are priced below $ 50, which makes it affordable to everyone. In case you are on a  tight budget, make sure you compare the prices and then take a call.

Many of the filters are priced less initially but are worn out quite soon. Make sure you also check the overall filtration capacity of the water filters to factor in the cost of replacement.



We are confident that using this portable filter buying guide, you would be able to select an ideal portable water filter to suit your needs.

It would be great if you do a prior analysis of which water source you would be using the portable filter with. For instance, if you are looking for a portable water filter for your hiking trips where you will have access to freshwater streams, it may have more sediments then say constituents like say chloride. The opposite may be right for public municipal water supply. This analysis will help you narrow down your choice further.
