Why Water Filters Are Necessary For Your RV

It was in the summer of 2016 when I got called from one my friends. He told me that he got admitted to a hospital after suffering from diarrhea and constipation. Weeks after, his diagnosis came up and revealed to us the cause of his sickness: contaminated water.

Let me tell you that even survivalists and preppers are not immune to contamination. We are just more logically paranoid than the rest of people, but still, our immune systems are still not impermeable.

That guy that I mentioned before is a better prepper than me. But he was still got afflicted by bacteria because he didn't have a water filter on his motorhome.

Right now, clean water is quite scarce. You can see a lot of water bodies, but only a few of them are safe for consumption. Not all the time we can get water from safe systems either. In any of these predicaments, one wrong move can get us a quick trip to the hospital.

Water filters are essential because they keep us safe. They ensure that the water we drink will not harm us. When they are there, you are confident enough that your water is as clean as it gets.

Even if you don't have a reliable source, as long as you have a top-tier water filter, your journey will go on without any complications.

Number Of Canisters

How to Choose the Best RV Water Filter

The best water filter can provide a holistic filtration performance. And sometimes, you can determine a filter's performance by just looking at the number of its canisters.

For instance, units that have only one canister are great for eliminating taste and odor issues. They can also screen some sediments, but not that much. On the other hand, a dual canister water filter is the best choice for water sources that are full of sediments.

These filters can also solve the problems of cysts, lead, and other types of bacterial contaminants.

You can always go with those water filters that feature three cartridges. You can guarantee that the water that passes through them is clean and free from funny odor and taste.


These are the fundamental things that you have to understand the best RV water filter. You have to ensure that the filter you get for your rig can meet your requirements. Make sure its specifications are suited for your setup. Otherwise, you can't still be sure about the purity of your water.
