Luckily, portable purifiers are here for you. Water filters make it possible for adventurers to enjoy clean and safe water from outdoor sources. They are not only portable but also quite reliable and super-efficient.

How Do Portable Water Filters Work?

The working mechanism behind water filters is no rocket science. They utilize a series of cartridges aligned along their structure to combat debris, protozoa, and bacteria. Also, these cartridges get clogged over time and might have to be cleaned or replaced.

Actually, some models have pre-filters that take care of debris and sediment. The subsequent extract then moves on to the filter cartridges. Pre-filters come in handy when filtering huge water quantities with huge amounts of dirt.

How Do You Purify Water When Hiking?

There are multiple ways in which you can purify water when hiking.

1. Water Filters

Here are some of the types of filters:

i. Gravity filters

This option is ideal for a group setup. It is composed of a filter and two reservoirs. Gravity filters have proven to be fast, convenient, and effective in filtering large volumes. With gravity filters, you can have four liters in less than four minutes. All you need to do is fill it up, hang it on a raised surface, and wait for clean water. No pumping is required in this case.

ii. Pump filters

As the name suggests, pump filters have a pump. This makes pump filters faster than gravity filters owing to the pumping mechanism. The option is great for a small group or a single person. Nevertheless, pump filters are prone to mechanical damage and require regular maintenance. Likewise, they tend to be a little costly. They adequately eliminate dirt, protozoa, bacteria, and odors.

iii. Squeeze or sip filters

With this kind of filter, you need to squeeze or sip in order to access clean drinking water. They are perfect for personal use. Another unique feature about them is their ability to draw water from deep water sources. They are fitted with a system of microscopic pores that undertake the filtration process.

2. Purifiers

Unlike water filters, purifiers are able to adequately remove small and evasive viruses. Most of them use UV light and chemicals in their filtration process.

3. Chemicals

The most commonly used chemical in purifying water is iodine tablets. They are very sufficient in eradicating small parasites although they leave an aftertaste. All the same, patience is required as they take up to thirty minutes to work effectively.

Are Iodine Water Purification Tablets Safe?

Iodine tablets are very good at purifying water. Yet, too much of anything – especially a chemical – is harmful. Exorbitant amounts of over 1100 mcg per day will yield negative effects on one’s health.

4. Boiling

Boiling is simple yet very potent against infection-causing pathogens. Even so, it is not the best option for a one day hike as you will have to carry a boiling container and make a fire. Another downside of this method is that it fails to remove sediment.

Does Boiling Water Kill Parasites and Bacteria?

Scientific studies have proven that water at seventy degrees Celsius will be able to kill 99.99% of viruses, protozoa, and bacteria within a minute. Hence, at one hundred degrees Celsius, the water will be totally safe for drinking.

What Is The Best Water Purification Method?

While water filtration will only expel protozoa and bacteria. The purification ensures that all contaminants including viruses are eradicated. There are several methods of purifying water but reverse osmosis is the best so far. It tackles a wider spectrum when it comes to removing pathogens.

What Will A 1-Micron Filter Remove?

A micron is the measurement of the openings on a water filter. They are designed to be smaller than protozoa cysts or bacteria for sufficient filtration. The average diameter or width of bacteria ranges from 0.2 to 2 microns. Thus, a 1-micron filter is capable of eradicating most of the cysts and bacteria from water.

Can Water Filters Remove Viruses? 

Water filters are only capable of getting rid of protozoa cysts and bacteria. They are not equipped to handle viruses apart from a few high-end filters. Conversely, purifiers are a good match for tiny viruses.

What Is The Best Water Filter For Camping?
