What is a Portable Water Filter?

These devices have inbuilt filtration systems that remove contaminants such as debris, sediment, and various other microorganisms from your drinking water.

You can use the straw and pull water up from the source. It goes through the filter and then into your mouth. Due to the portable and compact size of these devices, you can use them on the go. But to use these devices, you need to be present at a water source.

Some models of these portable filtration systems are for personal use, while others are for group purposes.

11 Best Portable Water Filters in 2022 - Reviews & Buying Guide

Types of Portable Water Filters

There are five different types of portable water filters that you can find on the market. We are listing them as follows:

●     Gravity-fed filters

These filters are great for anyone who wants to access clean water continuously throughout the trip. Two bags are connected with a pipe and a filter. One of them contains dirty water, and the other one will contain filtered water.

The dirty water goes through the pipe into a clean water bag after passing through the filtration hose. You can fold the gravity bag and stack it up when it is not in use.

●     Straw Filters

These are the best for backpacking as they’re very compact and lightweight. There are no bags to deal with these filters. You only have to stick one end of the straw into a water source and suck through the straw. Water will pass through the straw into your mouth. When you suck the water up into your straw, it goes through the filter, and clean water will enter your mouth.

●     Pump Filters

These filters come with ceramic filtering cartridges that are within a plastic filtering case. This cartridge has numerous tiny holes, and they trap contaminants to improve the taste of the water you are drinking. Some of these devices also come with a pre-filter before the ceramic filter to improve overall filtering efficiency.

●     Filtered Water Bottles

These look like regular water bottles but come with filters that take care of chemicals, protozoa, and bacteria to make your water safe to drink. These filter bottles are straightforward to use. And you will not have to deal with any hassles of chemically treating your water.

●     UV Purifiers

These are handheld devices that you can use for disinfecting your water using UV radiation. It has a major selling point, and UV radiation is right at the center of it. UV radiation is highly effective in killing off any bacteria and viruses. These devices are available in different shapes, but the water bottle shapes are most common.

What to Consider When Buying a Portable Water Filter System?

Here are all the essential features you must keep in mind when buying a portable water filter system.

●     Water Quality

You have to consider a unit or a device that provides you with the best water quality for drinking. You have to make sure that the filter can remove microplastics, heavy metals, bacteria, and viruses, along with protozoa, effectively. Go for a device on a system that treats all these harmful particles in natural water.

●     Flow Rate

Flow rate is also essential because you do not want to go for a very slow system and do not filter water quickly. Better flow rate also means that the water doesn’t take much effort to suck or pump up into the filter hose.

If that is the case, you will have to put in a lot each time you want to use your filtration system, and it can get pretty tiresome and frustrating.

●     Filter Capacity

Most systems come with a pretty good filtration capacity. It might range anywhere from three to five years before you start looking for a replacement. Some filters come with an extensive filtration capacity.

But if you do not travel frequently, then you might not need so much longevity. Some come with a filtering capacity of up to 100,000 gallons. These units are not ideal for those who travel less frequently. In such a scenario, a lifespan of a few years equally works well.

●     Product Weight & Portability

Portability is a must-have if you are looking for a filtering unit or device that you can use on the go. Therefore, go for a device that is easy to pack and carry with you on your trip. After all, it will not be portable if you cannot pack it up and carry it with you everywhere.

●     Ease of Use

Your filtration system should be straightforward to use. You do not want to end up in a predicament each time you use your filter. So, choose a system that is simple to use and clean after use. This way, you will not have to deal with any hassle while using it.

●     Durability

It must be made of quality materials. Metals are always better when it comes to durability. But they add to the overall weight of the unit too. So for lightweight designs, you have to go for plastics. But make sure that they are BPA-free and food-grade.

●     Physical Size

Of course, we are talking about portability, so size is always going to be a matter. If you want to keep your backpack free from any clutter, consider going for a compact unit. For example, hand pump filters and bottle filters take up more space because they have more components.

The smallest of all types of portable filters are straw filters. You can pack them up conveniently or can even carry them in your pocket.

Why Do You Need a Portable Water Purifier?

These devices or systems purify your drinking water and remove any disease-causing microorganisms. These microorganisms include protozoa cysts, viruses, and bacteria. Unfortunately, there are other harmful elements in natural water too. These include microplastics and heavy metals.

With a portable water purifier, you can get rid of them from your drinking water. Moreover, as these units are portable, you can carry them and pack them in your backpack. These purification systems ensure water filtrations are on the go.

11 Best Portable Water Filters in 2022 - Reviews & Buying Guide

Water Filters vs. Water Purifiers

The primary difference between the two is water filters can treat any bacteria or protozoa that are waterborne. But they cannot treat viruses. This is where water purifiers take the lead because they can remove viruses along with bacteria and protozoa. Therefore, you can say that water purifiers are far more effective than water filters.


What makes natural water unsafe to consume?

Natural water might look clean and safe, but it is not. More than 80 percent of wastewater goes back into the environment without getting any treatment. Apart from that, different microbiological pollutants such as viruses, bacteria, and protozoa contaminate the water.

Moreover, microplastics and heavy metals are present in the water, making this water unsafe to consume.

What standards or requirements do water filtration manufacturers have to meet?

There might be no legal standards or requirements that manufacturers of this system have to meet. As a result, you have to do your research and choose the best products.

Some products do come certified by NSF, US EPA, and ASTM. However, you will have to go through the specs and reviews of the units you consider purchasing.

What type of portable water filter is best to go for?

If you are looking for the most portable and lightweight of them all, you should go for a straw filter. You can palace it anywhere in your backpack or your pocket. Easy-to-stash water filters bag water filters or gravity-fed water filters.

You just need to empty the bag and fold them away. For personal use, the best options are filtered water bottles and UV filters. Each person can have their own and use the unit effectively.

Final Word

The best portable water filter on the market is the Sawyer MINI Water Filtration System. It might come with a slow flow rate, but it can handle most contaminants in the water. The device is pretty easy to use and clean. It is the best choice for personal use, and you can carry it conveniently.
