Buyers Guide

Five Things to Consider Before Buying a Portable Water Filter:There are several important factors to consider before you finalize a purchase or make a decision on which model of portable water filter you will buy. Here are some of the things to look out for:

1. Filtration Speed

Different models eliminate contaminants from the water at different rates. Some will be able to produce just a few ounces of clean water per minute; others are capable of producing almost 20 ounces of water in the same amount of time.Buying a unit that can filter water quickly can be advantageous if you are camping or traveling with a large group of people.

2. Weight

It’s pointless buying a heavy portable water filter if you’re traveling around a lot. Therefore, make sure you consider the filter’s weight before you decide on a model. The majority of portable water filters are small and compact, but weight varies in accordance with design, construction materials, and filtering technology.

3. Filter Capacity

Unfortunately, all filter cartridges expire at one point or another. Some models will last for only a few days, while others will keep filtering for many weeks and months. The highest quality portable filters utilize long-lasting filter cartridges.Some products will allow the filtration of almost 264 gallons of water with just one cartridge; others will clean up 100,000 gallons of dirty water.

4. Cost

The leading approach to finding a portable water filter that matches your budget is to have a figure in mind before you start searching for one. As with most products, portable water filters come in a range of shapes, sizes, and prices.Some use expensive materials, high-grade filters, and have the muscle of a big brand name behind them. Others are cheaper, but could be flimsy or have short lifespans. It’s a delicate balance, and the more money you spend doesn’t guarantee a better model.Believe us; there are many efficient models available at reasonable prices. So don’t break the bank before you’ve done plenty of research.

5. Ease of Use

Although these products are small and compact, some of them are almost impossible to use. Which is the last thing you need when you’re parched, halfway up a mountain, in the middle of nowhere.Many models come with detailed instructions regarding assembly and usage, so make sure you pack these if you’re worried about constructing or using a particular model.Or opt for a simpler model, like one that involves sucking water up through a straw. Only you will know that model that suits your individual needs.

Frequently Asked Questions

How Do Portable Water Filters Work?

Water filters use a cartridge or element to trap tiny debris, bacteria, and protozoa. As with all types of filters, repeated use leads to clogging, and filters must be cleaned thoroughly or replaced. Water purifiers usually rely on chemicals or ultraviolet light to eliminate any viruses.

What is Inside a Water Filter Cartridge?

A water filter’s primary filtering mechanism uses ion exchange resin and activated carbon. Activated carbon is manufactured using coconut shells. Ion exchange resin manages to reduce limescale, copper, and lead in any sources of water that need to be filtered.

Can Water Filters Remove Viruses?

Water filters are generally designed to eliminate bacteria and waterborne protozoa, not viruses. However, water purifiers can remove all three of these contaminants. The problem is, viruses are too small for filters to catch. Therefore, if you’re traveling to somewhere that you know is susceptible to viruses, you will need to purchase a water purifier before you drink from any natural source.

Is Purified Water the Same as Filtered Water?

Almost! Both of these water types are filtered in one way or another. However, purified water is cleansed and purified using additional processes. These typically involve reverse osmosis, deionization, and distillation.
