How to Get the Best Camping Water Purifier

There’s no shortage of water purifiers and filters on the market today. That much is clear.

But, even with the myriad of available options, they differ when it comes to holding capacity, the types of impurities that they’re designed to handle, and the amount of time they take to purify water. All of these factors contribute to their effectiveness for you specifically so you can stay cool while camping outdoors.

To help you in your search for the best camping water purifier for your needs, we’ve put together a short summary of the different purifiers you have at your disposal as well as their pros and cons.

Gravity Filters

This type of water filter uses the power of gravity to work and it has the capacity to handle large quantities of water.

All you have to do is hang the “dirty bag” which is another name for a water reservoir from a tree and channel the included hose to the water filter. The water that comes out of the water filter goes into another hose which channels it to the “clean bag.”

This process typically works through a single-stage filter. Needless to say, gravity filters are great for small groups and couples because of their large processing capacity. They work similarly to inline water filters.

Squeeze Filters

This is a single-stage filter that’s typically designed to get rid of protozoa and bacteria. But not viruses.

For best results, it’s recommended to only use this type of filter in clear water sources with not as much suspended organic matter or particulates that would prove too much for it.

The amount of time it takes for this type of filter to work will depend on the amount of water it has to work with.

The thing with squeeze filters though, is that they work slower the more often they’re used and you have to back-flush them with a cleaning syringe on a frequent basis. This way, there’s a fair amount of maintenance required to keep them working optimally.

Bottle Filters

Bottle and straw filters work through a single-stage process which is common in inline, gravity, and squeeze water filter systems.

First, you suck water from a bottle or the water source itself so that it can go through the filter before it goes into your drinking receptacle.

This type of water filter is perfect for when you’re camping next to an abundant water source and is mainly designed for individual use.

Pump Water Filters

Pump water filters are designed to get rid of protozoa and bacteria, while pump water purifiers take it a step further by also removing viruses.

Both models work with hand pumps that help you to filter out water from the source to a storage source.

It’s not easy using pump filters but they are quick and efficient and are suitable for individuals as well as couples. Most of them even come with pre-filters to help get rid of organic matter and particles coming from the water source.

Replacement filters are available to purchase separately and have on hand if you don’t feel like cleaning the one you currently have.

Ultraviolet Light Purification

Ultraviolet light is very effective at purifying water because it naturally kills viruses, protozoa, and bacteria.

Since it can’t remove organic matter and particulates, it’s best used on clear water.

Otherwise, it works fast and efficiently to purify large amounts of water. But, you have to make sure to pack extra batteries so it doesn’t run out of power.

Chemical Purification

You may have seen the purifying tablets or liquid purifiers at your drug store on the way to check out.

These are chemical water purifiers that typically feature chlorine dioxide to kill viruses, protozoa, and bacteria. The great thing about this ingredient is that it has no color or taste.

Depending on the product, it could take 15 minutes to 4 hours to purify enough water for one or two people.

Although compact and portable, these purifiers can be expensive. But, they’re definitely worth having even if as a backup for your main, larger water purifying system.

Water Purifiers vs. Water Filters

While the words water purifier and water filter are often used interchangeably, they have different meanings.

Water filters are often recommended for the average camping trip because it has the ability to get rid of bacteria like shigella, salmonella, campylobacter and E.coli, and protozoan cysts such as cryptosporidium and giardia lamblia.

These biological pathogens are dangerous and can cause some nasty side-effects that you don’t want to be dealing with while traveling.

But, the problem is that water filters can only protect you from these bacteria and protozoa, but are powerless against viruses. That’s because viruses are so tiny that most filters can’t even perceive them. So, if you want full-spectrum protection from everything then it’s worth investing in a water purifier instead.

In fact, a water purifier is essential if you want to go traveling around underdeveloped parts of the world. This is because you never know what to expect when it comes to water quality in some places.

What makes water purifiers so effective is the fact that they use chemicals like iodine to get rid of all of these undesirable and harmful elements in the water. They typically feature an internal cartridge or element to draw away bacteria, protozoa, and debris from the water.

The microscopic spores on the element are what draws away these bacteria from the water. As a result, you have to periodically clean it up to get rid of the build-up that happens naturally.

Final Thoughts

Well, there you have it! That’s how you find the right model, whether you’re going camping locally or internationally. Or you just want to add it to your emergency preparedness kit at home.
