15 Best Water Filter for RV Reviews

In this section, we’ll do exactly what you would expect from a product review section: we’ll review the RV water filters that we deem worthy of being called the best. We hope these reviews will give you some context and help you start understanding what you should be looking for in an RV water filter.

1. Waterdrop TSU 0.01μm RV Under Sink Water Filter System

Waterdrop’s TSU 0.01μm RV Under Sink Water Filter System stood out from other choices due to its straightforward installation. Waterdrop made this process simple by including everything needed for it with each purchase. It was nice not having to worry about finding the right adaptors or outlet hoses to make this water purifier for camper work.

Once I installed it, the product’s performance was quite impressive. Its 0.01-micron ultrafiltration membrane provides a water quality that my camper previously didn’t offer. As a result, I no longer disliked drinking my sink’s tap.

The device’s smart indicator system was another attractive aspect. It has lights for each filter, letting me know when each component’s due for a replacement. Due to this, I’m never surprised by cloudy or contaminated water.

Furthermore, I don’t have to replace the filters as much with this system. My previous RV water filter for hose/camper requires changes every three months. Thankfully, this one offers up to 24 months of filter lifespan to make it more practical and convenient.

I was also thrilled by the ease of changing the filtration parts. After all, Waterdrop incorporated an integrated waterway that helps prevent leakage. It ensures that users don’t have to stop the water supply when changing filters, allowing families to drink or shower without interruption.

Buyers will have a choice of two color options, as well. It’s a relatively standard selection between black and white, but both are lovely designs. I found myself choosing the black variation as it better suited what I wanted from these systems.

As for its flaws, I wasn’t a massive fan of the battery compartment being in the back. This location made it a bit more challenging to change batteries when necessary. It’s a minor issue but one worth noting when selecting an RV water filter for iron or other minerals.

2. Camco 40043 TastePure Water Filter

The first product on our list, the Camco 40043 TastePure Water, comes from a manufacturer that’s been a leader in the RV parts industry for a long time. And it shouldn’t surprise you that this particular RV water filter lives up to the reputation its brand has cultivated.

One of the reasons why it lives up to the reputation its brand carries is its large capacity. With this feature, this water filter should have no issues lasting a whole RVing season or even longer and allows for it to have a higher flow rate.

The higher flow rate will make sure your water gets filter quickly and efficiently. Some filters have a tendency to slow down your water’s flow, but this product won’t have this issue, and you shouldn’t even see any reduction in this regard.

It also has a 20-micron rating, which will be incredibly helpful in fighting against any contaminant that tries to get into your water supply. On the same front, the high sediment flow and carbon filter will also help keep these pesky issue-causing substances out of your water.

The built-in granulated activated carbon filter will also reduce any bad odors that emanate from your water. Therefore, the rotten egg sulfur smell will be a thing of the past if you put this filter to use.

You also have to like this product’s heavy-duty design. This water filter system’s entire design was made to ensure it lasts a long time. You’re not going to find a more durable and long-lasting option out there on the RV water filter market.

It doesn’t hurt that this product comes with a wrench include either. This aspect will make removing the product’s housing much easier. And it’ll also remove the hassle of trying to dig around inside your own toolbox.

The AQUACREST RV KDF Water Filter is one of the more versatile options on our list. See, this particular product has the added benefit of being interchangeable with the Camco 40045 water filter, which is quite practical as it gives more options as a consumer.

RV Water Filter Buyer’s Guide


In this section, we’ll go over all the basics about these products to ensure your buying experience is as easy as possible. It will give you a further understanding of what you’re looking for in an RV water filter.

Things to know before buying an RV water filter

Picking the best RV water filter can be an overwhelming experience. I mean, there are just so many options available to you, but there are certain factors that can help you restrict your search.

And this section will discuss these factors in detail to help make this process as easy as humanly possible.

Filter Size

One of the first things you’ll need to know is what filter size you’ll need? If you don’t, it could lead to a heap of issues you’ll want to avoid at all costs. A key in figuring this factor is also keeping in mind your water pressure.

See, the higher the water pressure, the bigger the filter size you’ll need. But by in large, the filter size you’ll need will depend on your filter needs. In other words, how much water you intend on going through the water filter.

How Much Water You Need Filtering

Understanding how much water you want to filter is something you must take into account before buying a water filter. You should be able to answer the following question, do you only want to use it for drinking water or on your entire RV water system?

Once you know the answer, you can easily apply it toward your search and find the water filter that can handle your water filtering needs. It sounds relatively simple and like common sense, but you’d be surprised how many people just buy the first filter they see without factoring in something this basic.

Ease of Use/Installation

Do yourself a favor and avoid buying a filter with a complicated installation process. It only makes your lives much more frustrating. I mean, there are plenty of options on the market that are simply installed.

This issue becomes incredibly essential when you remember that filters have to be changed every 3 to 12 months depending on the model. And you don’t want the changing process to overly complicated, or you’ll end up never using the thing out of pure frustration.

With this in mind, it’s best that you stick to the models that are easily installed and include a detailed instruction manual when you buy it. To determine whether a product is easily installed, you should also check the customer reviews.

Trust me; if someone found the installation or overall using process to be miserable, these reviews we’ll let you know. In some cases, it’ll be blatantly apparent that the manufacturer lied in their product description about the product being an easy install thanks to these reviews.


As with everything we intend on buying, the price matters. It should be one of the first things you discuss or think about before buying any product. And this factor doesn’t change with RV water filters either.

Once you outline a range you’re willing to spend on a filter, the number of options will lessen significantly. In doing so, it’ll make the overall process much less overwhelming, and it’ll quickly become the simple process that we’ve promised frequently in this article.

It’s also essential you remember that there’s always a bargain out there for you. There’s no reason to pay a significant amount of money for a filter that does more than you need. Instead, match your needs to the best filter that meets them and quickly put it inside your Amazon cart.

Micron Ratings

You’re probably saying to yourself what in God’s name is a micron rating? I know, I was when I first start looking into RV water filters. Well, an RV water filter’s micron rating indicates the size of the particles that the product will let through its system or kit.

In other words, the smaller a filter’s micron rating, the more effective it will be at filtering the contaminants out of your water. As a result, I’d recommend finding the filter with the smallest micron rating that’s within your budget and fulfills your filtering needs.


As previously discussed in this article, there are many different options when it comes to RV water filters. But the main three you’ll see on the market are sediment, carbon, and ceramic water filters.

Each one has a different scenario where it’ll be more effective than the others. For instance, if you have water that’s filled with sediment and particles, you should opt for a sediment RV water filter. It also essential we note that an inline or a customizable canister type filter would work in this situation as well.

But if you have that rotten egg smell coming from your water, these sediment water filters won’t do you a lick of good in most cases. Instead, you’ll want a carbon water filter as these are incredible at getting rid of any unwanted water odor, especially the granular activated carbon ones.

And if you’re worried about biological pests running rampant throughout your water; city water has been known to be contaminated with these nasty organisms. A ceramic RV water filter can more than get rid of these awful contaminants.

Of course, there are other types of RV water filters as well, but these are the main ones you should be aware of and will affect your search the most. However, if you find another type that meets your needs better than these, you shouldn’t have any doubts about buying it.

Customer Reviews

An essential resource you’ll come across in any buying experience is other people’s customer reviews. I know, reading these things can be quite dull and nauseating as sometimes people complain about the most unimportant things.

But outside of those reviews, you can learn a lot from the well-crafted reviews of others. And once you have read a numerous amount of them, you’ll start to determine where the product thrives and where it’s a little lackluster.

In other words, a pattern will form, and you’ll understand whether or not this water filter will meet all the requirements you need from it. Honestly, if you let them, these reviews could shorten your search by a significant amount of time.

However, you must refrain from allowing yourself to get sucked into buying a product just based on its five-star rating. In some cases, manufacturers will fake these ratings and inflate them, which will do you no good as a customer.

Therefore, it’s best to read these customer reviews before making your final purchase. If you don’t, you could end up with a malfunctioning filter that won’t do you any good. In fact, it might even cause you more problems.

What are the different types of RV water filters?

As mentioned previously, there are several types of RV water filters for you to choose from in today’s market. But the three main types are sediment water filters, carbon water filters, and ceramic water filters.

All of these three water filters have specific purposes, and we’ll go over each one below that’ll help you decide which one fits your situation the best.

Sediment Water Filters

A sediment water filter might be the most basic of these three types. It works similar to how’d you expect a mechanical strainer would as it catches particles and removes them from the water. Sounds pretty useful and straightforward, right?

Well, it is, and it’s often chosen by people looking to keep their faucets, water pumps, toilet valves, and water heater for RV in pristine condition. But there are some drawbacks to having this type of RV water filter.

Given it’s the most basic of the three types, you shouldn’t be shocked to learn it also requires the most maintenance. It also tends to damage entire RV water components. Therefore, you’ll need to be a little bit more aware during its use than its competitors.

But regardless, it’s still an ideal option for any RVer, especially, one looking to filter all of the water going into RV.

Ceramic Water Filters

Ceramic water filters work by having holes, which remove contaminants such as bacteria, sediment, asbestos, protozoa, and other issue causing substances from the water. However, these filters tend to have problems removing chemicals from the water.

Due to this, the new available ceramic water filters often come with carbon components, which take on the task of getting rid of these chemicals from the water. With this in mind, if you’re looking to make sure your water is safe from any unwanted chemicals, a ceramic water filter that has carbon components would be a suitable option for you.

Carbon Water Filters

A carbon water filter is another good option available to part-time or full-time RVers with some added qualities a sediment filter doesn’t provide. For instance, it improves the overall taste and smell of your water as well as the cleaning of other particles.

Therefore, if you can afford the bump up in price, I’d recommend getting a carbon water filter over a sediment one as it’s more convenient and practical. And these filters are incredibly well-suited to get rid of any nasty contaminants that might end up in your water: organic compounds, mercury, asbestos, lead, and other heavy metals.

It’s also essential we note that carbon water filters tend to come in three different variations solid block carbon, modified carbon block, and granular activated carbon. I tend to prefer the granular activated carbon as they’re typical reasonably price and are often more effective at getting rid of those problem-causing contaminants.

Any of these three types will ensure your RV’s water supply is clean and free of any issue-causing substances. In the end, it’s all about figuring out which type can rid your water of the issue you think might be causing it to be low-quality.

How long do RV water filters last?

It’ll depend on the model you end up buying. But typically, an RV water filter will last anywhere from 3 to 12 months. As you expect, each water filter will come with instructions regarding how and when to change them.

Therefore, if you’re like me and don’t enjoy the thought of changing your filter every three months, you should be ready to spend a little extra for the long-lasting models. It’s something you should think about before you make your final decision.

In my experience, the ones that can last for up to 12 months are usually higher quality than the three months ones. However, this lack of longevity doesn’t mean the 3-month ones can’t do their jobs quickly and efficiently.

How to install an RV water filter?

Just like the water filter’s longevity, the length of installation will depend on the model you end up purchasing. However, the entire install generally will take up less than an hour of your time and should be a rather straightforward, quick process.

It also helps that most of the RV water filters you’ll end up considering will come with interactive manuals depicting how to install them. Given this information, it’s imperative you read customer reviews about each product to determine whether or not the installation process is an easy one.

RV Water Filter FAQs

What is the best water filter for RV?

An RV water filter is one of the essential pieces of any vehicle that has a water hookup. Without one, you could be ingesting water that has a ton of unhealthy contaminants lurking inside of it, which is something nobody wants.

These devices are designed for one purpose; making sure your water stays clean of any harmful contaminants. And by doing so, it protects from things like chlorine, sediments, volatile compounds, heavy metals, and other impurities.

If you let any of these linger inside your water, all of them can cause you and your RV some severe issues. It’s also essential to note that the right water filter for RV can typically work on other applications and purposes as well: gardening, cleaning the car, filling up water tubs, etc.

I mean, there are some severe consequences to not having one of these devices. So please, invest in getting a high quality RV water filter for you. It’s not something you take lightly, especially these days when city water’s getting more and more suspect.

How does it work?

How an RV water filter works will ultimately depend on the model that you end up buying, however, each one will have the primary purpose of filtering the water that gets inside your water tank. Most water filters will be attached to your water tank by some RV water hoses.

These water filters will also come with a hose protector that’ll help prevent any straining from happening in your faucet or spigot. Some models are inline units, which combine sediment removal and carbon filtration as they remove any contaminants from your water.

These two features, sediment removal and carbon filtration, are among the best you’ll find in an RV water filter. Both of these will make sure your RV’s water supply is clean and ready for all its uses on your RV.

In most cases, these filters will also come equipped with KDF (Kinetic Degradation Fluxion). KDF works to make sure your water’s taste is the best it can be and removes any odor that might be lingering.

Therefore, the rotten egg smell that often comes with from city water will never be an issue you’ll have to face again. All you have to do is filter your water with one of these devices, and it quickly will become a thing of the past. The water filters with KDF also prevents bacteria from building up or collecting in your system when it’s not being used.

What are the most trusted RV water filter brands?

With any product marketplace, there’s going to be a few manufacturers that are a little ahead of everyone else concerning quality. In the case of the RV water filter market, the following four brands are often seen as the cream of the crop: Camco, Watts Premier, Culligan, and Clear2O.

Each of these brands is represented in our product review section, and you can trust that every one of their products is high-quality. But to further help you understand why these manufacturers standout, I thought a little background knowledge about all of them could give you a little perspective.


Camco has been in the RV product industry since 1966 and has been providing their customers with high-quality products from the very beginning. In doing so, they’ve cultivated a well-earned reputation for being top-notch in all areas.

And they’ve done so by ensuring “quality, innovation, and customer service aren’t just catch phrases at Camco- they’re [their] goals.”

Culligan has been a leader in water treatment needs for as long as the company has been in operation, which would be since 1936. The company’s place at the top of this massive market comes through their willingness to be “committed to making [their] efforts, large and small, beneficial for everyone in every community they serve.”

As someone who’s dealt with this company in the past, I can attest to their overall professionalism and compassion in their handling of their customers.


As a new company that’s recently made a name for themselves in the water filtration industry, Clear2O has gained a reputation for creating well-received products that provide their customers with fantastic results.

In doing so, Clear2O has quickly become “the leader in superior water filtration, bringing “Better Water by Design” to countless homes and RVs.” They’ve really taken it upon themselves to better their products to fit their customers wants and needs.

With all this background information, you can see that you’d be in great hands buying a product from any of these four companies. And honestly, if you buy from any brand mentioned in our product review section, there should be no issues with the quality of the RV water filter you purchase.

How much water should I filter?

Every filter will have its own maximum capacity regarding how much water it can safely clean. Due to this, it’s essential you check the product description before purchasing, which will tell you how much water the water filter can handle.

In other words, it’s really up to you regarding how much water you should filter. Some models can handle all the water going inside your RV and others can only handle some of the water.

It’s all about finding the right model that can adequately handle the amount of water you intend on filtering. With this in mind, please remember to check the filter’s capacity before putting it in your Amazon cart; you don’t want to buy one that can’t handle the job you bought it for, do you?

How often you’ll use the filter?

You can use a water filter for camper usage or an RV inline water filter until they require being replaced. There isn’t a limit on how often a person can or needs to use these products. It’ll vary drastically based on your chosen option and overall water needs.

But I can provide a timetable for how often filters will need replacing. In most cases, RV owners will get anywhere from 3 to 6 months without needing a change. Any decrease in water pressure is often the telltale sign new filters for travel trailer usage are required.

Of course, a high-quality RV filtration system can extend this lifespan past six months. An excellent example would be Waterdrop’s TSU 0.01μm RV Water Filter System. The UF filter has a 24-month lifespan, which is almost unmatched in this marketplace.

What is the warranty?

Most water filter system for RV devices will come with a warranty. These policies often range between a couple of months, 1 year, and five years. Some models for camper trailer even offer a lifetime warranty to ensure customers’ needs are always met.

I’d suggest choosing an option with such policies to ensure you have coverage. After all, a warranty can protect users from buying a malfunctioning product or any accidental breakage. I can’t even describe how many times these warranties have saved me significant time and money.

But I must warn you about how some brands will advertise a warranty without any intention of honoring it. So it’s essential to do research by reading through customer reviews. These resources will alert you to any problems regarding an offered policy.

Should I filter all the water used in RV or only the drinking water supply?

As discussed in the previous part of this section, it really depends on what you want out of your RV water filter. Some people only purify the water they drink, while there are others who filter all the water that enters their RV. It’s all about what you prefer.

In my personal experience, I’d always opt for filtering all the water that goes into my RV. It’s more of me being paranoid about my well-being than anything else, but it has been proven to improve skin, nail, and hair health.

Due to this, I always felt like filtering all my water was the best option. However, getting a system that’ll do so will cost you an extra bit of coin. In the end, it’s all about weighing the pros/cons and deciding which method fits your particular needs the best.

Should I use reverse osmosis (RO) for my RV? when?

Reverse osmosis is a process that can convert your dirty, gross tap water into pure, delicious salt-free water. And it can represent a worthwhile option for RV owners if they can afford it, which is where the problem beings with these type of systems.

A standard reverse osmosis system can run you anywhere from 300 to 500 dollars, which is a big chunk of change. Now, there’s another issue that doesn’t get talk enough about with these type of systems: brine.

See, the water that doesn’t make it through the RO system is called brine. And under the perfect conditions, 70 to 80 percent of the water thrown through at your RO system becomes brine. Therefore, only 20 to 30 percent becomes the pure, salt-free water these devices are made to produce.

In other words, if you’re using 20 gallons for your daily activities, about 60 to 80 gallons of water is being wasted to create the coveted pure water. Sounds like a colossal waste of water, right? Well, it is, and it’s something you should take into account before buying an RO system.

As a result, if you want as much pure water as possible, I guess you could buy yourself a reverse osmosis system. But honestly, with the heightened price and waste of gallons of water, I’d stay away.

Can I use RV water filters for hot water?

Most RV water filters aren’t meant for hot water. And if you do use one for hot water, it can cause a mess of problems. But you can always check with the manufacturer themselves if you find yourself in need of a water filter that cleans hot water.

In my search, I honestly couldn’t find one that had this capability. However, you might have better luck in your search than mine. But regardless, if you fully intend on filtering hot water for whatever reason, always check with the manufacturer first just to ensure it’s safe.

How to clean RV water filters?

Since there are so many types of RV water filters, it’s hard to talk about generally cleaning one. However, most models will make the cleaning process incredibly easy and depicted in excruciating detail in the manual that comes with it.

If all else fails, there will most likely be a YouTube video showcasing the precise way to clean your specific water filter. In any estimations, your manual should have you covered. I know, some of you might have an aversion to using it, but with products like these, it can be a massive help.

Don’t let your pride get in the way. Use the manual and watch all your questions fall to the wayside. You might be shocked by how much you learn from something as rudimentary as the instruction manual. After all, there’s a reason why the manufacturer includes one with every purchase.

Where to buy an RV water filter?

In my personal opinion, the best place to buy an RV water filter is online through Amazon. I know, this recommendation seems like a common sense type answer, but there isn’t a better place to get one nowadays.

Now, if for some reason you don’t want to shop on Amazon, your local Walmart, Lowe’s, or Home Depot should have a few options available for purchasing. But these models will have an uptick in price compared to what’d you find online.

And if you want to boycott Amazon, there are other online sites you can search for RV water filters. For example, Camping World, has numerous options available for you to peruse and find an appropriate match with your RV.

In the end, I’d still put Amazon above all the other options I mentioned. The site really has taken control of almost every marketplace, and it will have the most options available for you to look at as well as the best deals.

Don’t overthink it and stick to shopping on Amazon. It’s your best bet.


After all this reading, I don’t have a doubt in my mind that you’re ready to start moving your way towards a final decision. Just remember to be realistic about what you want in your RV water filter and find an acceptable model that fulfills all your needs.
