Why You Need an RV Water Filter
Purified water is extremely important no matter your living condition. Water sources can be contaminated by sediment, parasites/bacteria, heavy metals, and other microscopic dangers. Drinking non-purified water can lead to health concerns for you and your family. No one wants to spend vacation at a hospital.
Living or traveling in an RV increases risk. You’ll be hooking up to various water sources and you won’t know what the quality of the water might be. That’s why it’s so important to ensure your RV is equipped with a water filter that can handle any job. The truth is: water sources can become contaminated all the time. Campground owners and maintenance crews might do their best to keep their water sources clean, but they can’t catch everything. In 2018, a Minnesota campground found their water sources contaminated twice by E. coli. Yikes.
Here are some common dangers with campground water sources…
Bacteria, Fungi, and Microbial Contamination
It’s scary to hear, but it’s true: water sources can often be contaminated by germs, fungi, and other illness-causing microbes. These contaminants can cause major sicknesses, including but not limited to: Giardia, Norovirus, and even Hepatitis A. No water filter can filter out everything, but setting up a proper filtration system can ensure you’re more protected.
Sediment, Dirt, Silt Contamination
Ground disturbances from geological events (like earthquakes) or man-made events (like construction) can shift the ground around water sources. This can lead to dirt, silt, and other sediments being introduced into your drinking water. Water filters are especially good at filtering out hard contaminants like this. Drinking unfiltered water filled with sediment can lead to sickness.
Heavy Metal Contamination
Some water sources use metal piping that can rust over time. Metal flakes and shavings can enter your water when this happens. Drinking these microscopic metal pieces can cause serious problems! They can cut up your mouth and throat, cause infection, or even lead to poisoning!
All these complications can be mitigated. All you need is a good water filter. And you’re in luck! You’ve got options…
RV Water Filter Options
Getting a water filter for your RV is surprisingly easy. There are tons of online retailers that provide wide selections. Amazon is always a wonderful place to pick up anything you need. But, maybe you aren’t sure what kind of filter to look for? No worries! This article has you covered.
Your biggest consideration should be how much of your water supply you want to purify. Do you want to purify all the water going into your RV or do you just want to filter the drinking water? This determine the type of filter to search for. You should also consider how much space the filter will take up. And, of course, you should figure out a budget.
Water filter types can vary, but here are the basics…
Whole RV Filtration
Water purifiers intended to filter all the water going into your RV are often called “whole RV filters”. These filters can attach directly to the water hookup outside your RV, to your water intake hose, or can be installed within the RV itself. These are generally divided into canisters, with one, two, or three-canister options available. Generally speaking, more canisters means better filtration. More canisters also means the filter takes up more space, too, so watch out for that.
There are also whole RV filters, called “inline filters”, which are usually a single canister, low-use system. These are the cheaper versions of whole RV filters and work for a shorter period of time. These inline filters are great options for people who use their RVs intermittently. Full-timers should definitely consider larger systems.
Drinking Water Filtration – Under-the-Sink Filters
Under-the-sink water filters attach to the lines running underneath a sink and filter ONLY the water coming into that sink. They come in a range of sizes, just like their whole RV counterparts. Space is a large consideration here because they install under the sink. Keep in mind that not all RVs provide access to the plumbing underneath the sink, so you’ll need to ensure yours does before buying one of these filters.
Drinking Water Filtration – Countertop Filters
Like under-the-sink filters, countertop water filters only filter the water in the sink to which they’re attached. Instead of going under the sink, they attach directly to the tap. This means you won’t have to worry about how much space the filter uses under the sink, but you might need to worry about counter space. In an RV, every inch counts!
RV Water Filter Installation
Installing the various types of portable water filters can be a challenge because there are so many types, so you may need to rely on your specific filter’s manufacturer to provide specific installation information. If you aren’t comfortable doing it yourself, don’t worry. Many manufacturers provide professional installation as a service, and general plumbing services can usually assist you with installation as well. If you’d like to give it a shot on your own…
This video provides installation information on a filtration system that connects to your intake hose.
This one describes installing a basic under-the-sink system.
And this one shows you how to install a countertop system.
Again, if you have specific questions, consult either your filter manufacturer’s instructions or a professional plumbing service.
