The Best RV Water Filter
If you are looking to filter all the water going into your RV, then an inline filter is the way to go and the TastePure is one of the best.
Camco claims its filter can last an entire camping season, and we like the sound of that. Attached to your water hose, its wide body is a boost when it comes to water volume and flow rate, making it a really functional and practical way to clean the water going into your RV.
Using a 20-micron granular activated carbon filter, the TastePure removes bacteria, sediment, chlorine and general contaminants as well as sweetening up the water odor to produce tasty and clean water to drink and use for washing. It also uses KDF (Kenetic Degradation Fluxion, if you really need to know) technology to stop nasty fungi, bacteria and mold in their tracks. No assembly required; with this Camco water filter it is a case of set up and go.

Best RV Water Filter Buying Guide & FAQ
Things to Look for When Buying an RV Water Filter
Before choosing your RV water filter, you need to be sure you’re picking the right unit for your RV’s specific water filtering needs. To help, here’s the main things you need to consider:
What Water you Want to Filter
It’s important to be clear on what you want to filter before you start. Are you wanting to target filter water in your RV, eg. water coming through the kitchen taps or are you wanting to filter all the water before it enters your vehicle’s system? Also, how clean and pure do you want the finished product – are you looking to only remove particles or are you also wanting to fish out biological/chemical contaminants and improve the taste and odor of your RV water supply?
We’ve more on the actual types of camper water filter units in a moment, but in the meantime, you also need to know about the different filter materials used. Here’s our quick round up:
A sediment filter works in a similar way to a strainer, by catching particles in the water. The main plus point to a sediment filter is that it protects your RV water filter system from clogging, but the downside is that it requires more maintenance than other filter types. Also important to note is that filters are rated by the size of particles they remove in microns – one micron equals one-thousandth of a millimeter, so check the micron number on the box to see how low your sediment filter will go!
Carbon filters not only filter out particles but also remove contaminants and help to improve the water’s taste and smell. There are three types – granular activated, solid block and modified carbon block. Granular activated is the least expensive but still an effective carbon filter.
This type of filter has small holes to screen out sediment, bacteria and other contaminants in the water. On their own, however they don’t remove chemicals contaminants you can now buy units that have a ceramic filter with a carbon component to do the job.
You want to be able to fit your new RV water filter with minimal fuss as you have a road trip to go on! Once in, you need to be able to easily operate the filter system and its overall maintenance should not be too complicated.
Weight and Storage
The size of the filter also depends on the size of your RV and its storage options for spares. Large bottles can be heavy and awkward to store, particularly if you’re on an extended journey or are frequent road trippers so bear this in mind.
Why You Should Use an RV Water Filter
Whether you’re a regular weekend RV user or only take it out for a week-long blast once or twice a year, you want to be sure you can drink and wash with clean, tasty and safe water. With different locations and pitches, you also need to be confident in the quality of water supply where you hook the RV up to each night. Whether it’s campsite-supplied water, chlorinated city water or from a well, it’s a given that there will be some level of impurities and sediment. Not only does impure water run the risk of making you sick, the impurities can also clog up your RV’s systems and cause some expensive damage.
RV water filters do what their name says they do – they filter out the nasties in the water tank before you use it. They can be as simple as a fix-it-yourself inline water filter unit you add to the pipe under the sink to sieve out particles or they can be full-sized water filters you fix externally to clean out all the impurities and contaminants in the water coming from the campsite’s water supply and into your RV’s own water tank.
Camper water filters are designed to filter out sediments and impurities in the water that may affect the overall water quality and taste. They are NOT water purification systems – so if your water source is snot safe to drink, your RV water filter will simply not cut it, you need something a little more hardcore.
Different Types of RV Water Filters
There are different types of RV water filtration systems that have various capabilities and features. The type you choose for your RV should be based on your specific filtered needs and whether you want all the water coming into your RV filtered or just targeted water points inside your RV.
- Inline filter
This system fits directly to your RV’s water entry point so filters all the water supply coming into your vehicle. This is a good all-round filter for sediment and contaminants, as well as improving taste and odor, depending on the type of filter material it uses. You can also get an inline water filter that fits to the pipe leading to your kitchen tap.
- Compact canister
Similar to the whole unit used in homes, this canister is designed to fit on to the water hose or inside your RV, and depending on the model, can also be customized to your specific needs. The compact size is a bonus too. Canisters are also a good option if you want a better water flow and can also come in dual or even triple canister systems for specific filter tasks.
- Reverse osmosis
RO is a good option if you want to purify your water (although a word of caution, it also removes minerals).
How to Clean RV Water Filter?
Most RV water filters can run happily until their central filter – whether it is a sediment, carbon or ceramic – needs changing. There should be alerts on your filter to tell you when these filters need to be changed. To keep the whole RV water filter clean, it’s more a case of ensuring the connections are clear and clog free, which you should check on a regular basis. You will also need to clean and sanitize your RV’s fresh water tanks periodically to prevent stagnation, including before and after storing your vehicle for the winter. For further guidance on cleaning your RV water filter, check out its user manual.
Best RV Water Filter FAQ:
Q: How often should I change my RV water filter?
A: On a simple level, if you notice the taste or odor of your filtered water is not as clean as it has been or if the flow rate suddenly drops, then that’s a sure sign the filter is losing its effectiveness and could do with a change.
Some models also have an indicator to show you when filtering abilities are running low so you can prep to change it. Do read the instructions of your particular RV water filter for their recommendations. Around three months seems average for the simpler, less expensive water filters whereas canister filters can go for six months or so without the need to change.
Q: How do I install an RV water filter?
A: Installation of your new caravan water filter should be relatively easy and uncomplicated as they either fit on the external water hose leading into your RV or to the pipe under your sink. The best advice is to follow your new product’s instructions or get a plumber to help if you really need it!
Top tip – when fitting your filter and hooking it up to a campsite’s water supply, make sure you check the water pressure. Most RV water lines can handle around 100psi and the water pressure in most RV parks and campsites are low enough that you don’t need a pressure regulator so there shouldn’t be a problem. But if the water pressure in the campsite is too high, it could burst your RV’s water line.
Q: How much water should I filter?
A: For all-round convenience, many RV’ers recommend going for a full water system filter that cleans up all the water coming directly into your camper, which means your drinking water, as well as washing up, showering and bathroom water are all filtered for sediment and contaminants (depending on the type of filter used). This is also the best route if you have concerns about overall water quality of the campsites on your trip route. But if you just want to filter drinking water, then camper water filtration system in your RV’s kitchen will suffice. You could choose this option if the water is not too bad or if you are wanting to keep an eye on cost or space. The downside is that you may still have to put up with taste and odor issues when showering or cleaning your teeth.
Q: Can I use it for hot water?
A: No. Most manufacturers do not recommend running hot water through their RV filter units as they’re only designed for cold water. Hot water can actually reverse the process of chemical absorption, releasing contaminants back into the water.
Q: Should I filter all the water used in RV or only the drinking water supply?
A: For all-round convenience, many RV’ers recommend going for a full water system filter that cleans up all the water coming directly into your camper, which means your drinking water, as well as washing up, showering and bathroom water are all filtered for sediment and contaminants (depending on the type of filter used). This is also the best route if you have concerns about overall water quality of the campsites on your trip route. But if you just want to filter drinking water, then camper water filtration system in your RV’s kitchen will suffice. You could choose this option if the water is not too bad or if you are wanting to keep an eye on cost or space. The downside is that you may still have to put up with taste and odor issues with the water.
