Choosing Your Best Portable Water Filter Smartly

According to the U.S. Environmental Protection Agency (EPA), “90% of the world’s water supply is contaminated, considered unfit for human consumption” .

And that's the main reason why portable water filters (purifiers) have become an important necessity for travelers, hikers, campers, backpackers, as well as for emergency water needs. [1]

However, not all portable water filters are created equal.

Each will come with different features that provide different results.

So to get the right unit that fits perfectly to your need, the guide below will help.


Choosing Your Best Portable Water Filter

1. Filter Types
Ceramic - has a long life (mostly can last up to 2,000 liters) and can be cleaned many times before being replaced. Unfortunately, it can get clogged easily.

Some of the ceramic filters can also come with a carbon core, which helps to remove chemicals from water.

Structured Matrix - dense and honeycombed material that can strain out really tiny pathogens.

Fiberglass - more fragile than ceramic, but still effective at eliminating particles.

Hollow Fiber - allows water through tiny pores and into the core, where pathogens are strained out.

Silica Depth - works by having multiple levels of different sized grains, going from largest to finest.

It catches different sized particles and organisms as water is pushed through its levels of density.

2. Micron Size
A measurement of the pore size in the filter media. The smaller the pore size, the more pathogens the filter can strain out. [2]

3. Flow Rate
Flow rate shows how fast a unit processing the water.

A flow rate of greater than 1 liter per minute is fast enough. The rule of thumb is, the larger the surface area of the filtering medium, the faster the flow rate.

4. Other Features To Consider:
• EPA Certification

5. What Other Users Have Said
There is a great advantage if you buy your portable water purifier online is that you can see directly the opinions of other users.

And that is why large and trusted online retailer like Amazon.com displaying their customer reviews including the star rating. It will give you a real picture of a product you plan to buy.

The more the number of buyer reviews and the higher the star rating, the better the product in the eyes of consumers.

For your information, people who can submit a product review on Amazon.com must make the purchase first. So rest assured, you will get an honest review from them.

Now, get yours!!!
