An off-road water filter is a vital item that purifies water from any source by removing dirt and other contaminants that are dangerous to health.

Off-road water filters vary from brand, design and usage. If you’re a tourist or on explorer mode aboard your Recreational Vehicle (RV), an off-road water filter that lasts from 45 to 60 days of use should be enough.

However, if you’re permanently living in your RV, you have to usually replace them on a monthly basis due to the fact they get clogged and unfit for use.

Off-road water filters are classified into three types. Are you after the thorough process of cleaning water? Or are you after of the portability and mounting convenience, too? Each type performs a specific function based on your preferences.

What Is a Micron?

If you’ve come across the term, “Micron,” while shopping for the right off-road water filter, it’s a unit of measurement that describes the particle or residue size the off-road water filter can remove from the passing water.

Bear in mind though, there’s no such thing as an exact particle size since a micron is only a general estimation.

There are two types of micron ratings that have a varying degree of usefulness:

The first is nominal which measures the amount of collected particles at a given particle size. For example, an off-road water filter can remove 95% of dirt particles under 5 microns.

The other is absolute which is very important in capturing bacteria or other contaminants that aren’t visible in plain sight because they’re smaller than a strand of hair and dust.

As a general rule, the smaller an off-road water filter’s micron capacity, the more thorough and effective it is in terms of its water cleansing technique.

Some Micron Particle Ratings

Particle Type Particle in Microns
Beach Sand 100-2000
Human Hair 70
Household Dust 40
White Blood Cells 25
Bacteria 3
Lead Dust 2

How to Replace an Off-road Water Filter

Moving from different places one at a time means you’re subjecting your off-road water filter to different substances and particles. In fact, getting your hands on the necessary off-road water filter can be a challenge because you should not only understand how to use it but also learn how to maintain it the way it should be, which includes correct replacement.

Don’t forget to turn off your water source first, before proceeding with the off-road water filter replacement because you wouldn’t want to waste a large amount of water as it spills on the ground.

Such a replacement is easy because it only involves a few steps that even the not-so-mechanically-inclined person can do. However, you might need a wrench to fully secure its mounting hardware in place, to ensure proper installation. Click here for the full instructions.
