#7. Best Three-Canister: Frizzlife Under Sink with Brushed Nickel Faucet SP99

You can think about the advantages of a three-canister water filter if you often visit places where you are aware that the water is contaminated.

And the Frizzlife Under Sink Water Filter System is one of the few products available today that performs better.

This filter won’t take up extra counter space or refrigerator space in your RV since it is designed to be fitted beneath the kitchen or bathroom sink.

Additionally, you won’t have to constantly install and remove it from your RV’s exterior drinking water line while setting up in a different RV park or campsite.

It will thus take a little longer to install initially, but it will continue to operate for you as long as you change the internal filters on a regular basis.

You may save up to 70% over traditional water filters by building this filtration system with replaceable filter cartridges over time since you’ll just need to replace the cartridges rather than the full filtration system.

This filtering system includes a brushed nickel faucet in case you also want to replace the faucet in your RV’s kitchen or bathroom sink.

This enables you to improve the cosmetic finish of your RV’s interior decor while ensuring that you always drink clean, safe drinking water.

Three stages of filtering are used by the Frizzlife filter.

Sediments, rust, dirt, sand, and other big particles are removed in the first step using a five to ten micron filter.

Chlorine, chloramine, smaller particles, and other disagreeable tastes and smells are eliminated in the second stage using a three to five micron carbon block filter.

#8. Best RV Reverse Osmosis: Waterdrop G2 RO Tankless Osmosis Water Filter

Reverse osmosis, sometimes known as “RO,” is a filtering technique that is highly efficient for long-term usage without requiring regular filter replacement.

So be sure to check out the Waterdrop G2 RO Water Filtration System if you’re looking for a RO water filter.

This filter has a flow rate of 0.28 gallons per minute and a tankless design, which both saves you space and contributes to the filter’s high flow rate.

Additionally, it makes use of composite filters, which have a long shelf life and should generally be changed every six months or so.

Since this filtration system is intended for family RVing with greater levels of water consumption, that filter replacement rate holds true even at high usage rates.

An activated carbon block and a polypropylene (PP) membrane are included in the filter’s construction.

Sediments, rust, excessive chlorine, fluoride, and a total of more than 1,000 pollutants are all successfully removed by the membrane and carbon block filter.

This contains substances that shouldn’t be in your water, such as heavy metals, colloids, big particles, and other organic components.

The tankless design of this filtration system makes it about 70% smaller than most conventional under-the-sink water filters, even though it is intended to be fitted under the sink in your RV.

Waterdrop created this filtering system with integrated electrical and water circuits since it is intended to tuck away behind your sink.

Due to this design, the likelihood of electrical blackouts caused by water leaks from other parts of your RV are also reduced.

By following the comprehensive installation instructions that are included with the filtration system, the Waterdrop G2 may be installed in approximately 30 minutes.

RV Water Filtration System Types

There are four main categories in which most RV water filters may be found.

Therefore, it makes sense to begin by outlining each kind and discussing some of its benefits and drawbacks.

#1. Deposition Filters

Similar to a regular pasta strainer, sediment filters function by allowing water to flow through considerably tiny pores.

These filters are excellent at eliminating substantial particles from your water as it moves through the strainer, living up to their name.

The sediments often end up remaining in your filter and building up over time due to the way they are made.

As a result, you could find that your water’s flow rate slows down over time.

Therefore, it is necessary to clean and flush sediment filters more regularly if you want to maintain their effectiveness and extend their lives.

The finest RV filters often use various filtering techniques.

However, putting a sediment filter in your RV is often the very minimum level of security you should think about doing to ensure cleaner drinking water.

#2. CO2 Filters

The best option for enhancing the flavor and odor of the water in your RV is generally thought to be an activated carbon filter.

These versions also lessen the unpleasant chlorine taste that some water has, which is not something you can anticipate from a sediment filter.

Granulated activated carbon, a solid block of carbon, or a modified carbon block are the common materials for the filter component.

Although they aren’t nearly as efficient as the other forms, granulated activated carbon filters are the most often used and least expensive.

Small grains of activated carbon, which are quite similar to the charcoal some people use for campfire cooking, are passed through your water to make them operate.

Since water is less likely to create channels within the filter, filters that employ solid blocks of carbon are more efficient.

By doing this, you can be sure that the carbon filter truly contacts all of your water.

These elements are created by crushing activated carbon, which is subsequently solidified under high pressure.

These filters are more costly than certain other kinds of filters in part because to the additional manufacturing procedure.

A modified carbon block that performs similarly to a solid carbon block filter is used in the third kind of carbon filter.

However, improvements made to these filters allow for a higher flow rate and longer lifespan.

As you may anticipate, this might also cost more money.

Many of these filters are efficient in removing impurities, including harmful heavy metals like mercury, asbestos, lead, and other volatile organic compounds, in addition to enhancing the taste and flavor of your water.

#3. Pottery Filters

Ceramic elements with tiny pores are used in ceramic filters.

For your RV’s clean drinking water supply, these filters filter away sediments, giardia cysts, bacteria, and protozoa.

These kinds of compounds are successfully removed, however they are less successful in removing chemical contaminants.

Some ceramic filters do, however, include a carbon element that enhances their capacity to filter pollutants and, as a result, enhances the flavor and odor of your drinking water.

As a result, be sure to ensure that the ceramic filter you’re interested in contains a carbon filter element of some kind.

#4. Filters for Reverse Osmosis

The most cutting-edge sort of filter is a reverse osmosis unit, which can create water that is almost completely clean.

They depend on a membrane that is semi-permeable and can prevent any particles bigger than a single water molecule.

As a result, they are also particularly good at purifying your water of nitrates, arsenic, fluoride, perchlorate, and hexavalent chromium.

Chlorine is the one substance they cannot get rid of.

So, if you choose a reverse osmosis filter, make sure it also has a carbon element of some kind to get rid of chlorine.

The Right RV Water Filter Depends On You.

You may ask what kind of filter would best meet your demands when it comes to a water filtration system.

The best filter for your RV will primarily rely on your demands for water filtration and how you RV.

Here are some considerations to ponder when selecting a water filter for your RV.

#1. What Should You Filter?

You may choose the best kind of filter by being aware of the most typical forms of pollutants that need to be filtered.

You may always do a water test to determine precisely what is in your water if you only park your RV in one or two spots on a regular basis.

You’ll be able to pick the suitable filter type when you have a clearer understanding of what you’ll need to filter.

It’s not practical to do a water test every time you enter a new park if you’re an RVer who travels often.

The majority of RV parks have access to municipal water, which usually contains chlorine.

Having said that, you can typically rely on municipal water to be treated to eliminate germs that might cause waterborne diseases, thus a carbon filter will typically be sufficient to enhance the flavor and odor of city water.

However, some parks could provide their own water via a well on the grounds.

High concentrations of sediments, heavy metals, and potentially dangerous bacteria and germs are often found in well water.

This will call for a filter that can get rid of these kinds of impurities.

Furthermore, regardless of the source of the water, certain locations have “harder” water than others.

‘Hard’ water often has high concentrations of calcium and magnesium, which may sometimes accumulate in your RV’s water pipes and eventually lead to damage.

The final fact is that RVers are better served by a more thorough filter.

RVers who want to travel often need a filter that can get rid of sediments, chlorine, bacteria, and a wide range of chemical and metal pollutants.

This will offer you the assurance that your filter will work hard to protect you regardless of the water quality wherever you connect up next.

#2. How Much Filtered Water Is Required?

How much water you want to filter will be your next choice.

You can get away with an under-the-sink model if all you want to do is filter the water that comes out of your kitchen sink for drinking and cooking.

However, you’ll need either an inline filter or a canister-style system if you want to filter all of the water entering your RV.

Remember that installing a whole-RV filtration system can also safeguard your pipes against the accumulation of calcium, magnesium, and particles that may cause plumbing problems, even if you may not feel like you need filtered water for your shower or toilet flushing.

#3. When Will You Use the Filter?

You should also think about how often you intend to use your RV water filter.

RVers who live in their vehicles full-time will need a filter that will last longer and be more robust than those who just use them sometimes during the summer.

Additionally, filtering from a wider range of surfaces will need a bigger investment in a filter with more features.

You may probably get away with a simpler water filtration arrangement if you virtually always hook up to city water when traveling in your RV.

However, you’ll need a filter that can get rid of the kinds of germs and microbes that are typical of rural water sources if you plan to keep your RV off the grid for weeks or months at a time.

Additionally, consider how long a particular filter will last before needing to be replaced.

You will always need to arrange your RV trips around the possibility that you may need to change a filter, particularly if you’re living remotely, if you’re not always in a location where you can quickly dash to the next Wal-Mart to acquire a new filter.

#4. Size in Microns

The micron rating of a filter provides extra information about the size of the particles that it will let to pass through.

Consequently, a filter rated at 0.1 microns will filter more particles than a filter rated at 2 microns.

A sign like this “m” may also appear in front of a filter’s micron rating.

This is short for submicron and is exclusively used by filters that remove the tiniest particles from drinking water.

#5. Installation and Use are Simple

We strongly advise picking a filter with a simple installation procedure unless you have a lot of expertise with plumbing systems.

You run the danger of jeopardizing the system’s watertight integrity if you have to make modifications to your RV’s current water system in order to install your new filter.

After you install your new water filter, the long-term repercussions might be disastrous if you don’t realize that your RV’s water system has a little leak.

If left unattended, even the slightest leaks may result in dry rot, mold, and/or mildew.

For this reason, if you’re uncomfortable with the installation procedure that goes along with canister-style systems, we advise using an inline water filter.

These filters don’t need any tampering with the pipes in your RV’s water system, but you will need to screw them into place each time you connect to a new water source.

However, these filters are the simplest to utilize over time provided you are confident in your ability to install a canister-style system and are at ease with plumbing.

Your procedure for connecting to a new water source will basically be the same as it was before installing a new RV water filter once you go through the more difficult installation process.

#6. Price (And Cost Over Time)

It’s critical to look beyond the initial expense of a new water filter while considering your bottom line.

You should also take into account the expense of maintenance as well as a complete filtration system replacement.

Furthermore, filters with more difficult installations often have higher lifetime maintenance costs.

Therefore, be sure to take this into account while evaluating water filters to determine which one will provide you the most value.

Which Is Best For You, Then?

The Camco 40043 TastePure is our pick for the finest all-around RV water filter because it’s simple to install, very flexible, and incredibly economical.

The regular garden hose you use to connect your RV to city water easily screws into the inline filter.

Additionally, it enhances the flavor and odor of your water while removing a broad range of pollutants and heavy metals.

However, if money is limited and you’re searching for a filter that’s inexpensive but still delivers good results, we suggest the Hydro Life 52700 Inline Water Filter.

This filter can last up to 8,000 gallons and can remove sediments, bacteria, and chemical impurities for your water despite its very affordable price.

Along with being very simple to install, it has uses other than just RV water filtering, such as urban farming, hydroponic gardens, and more.

#1. How Does A Water Filter For An RV Operate?

The present water system in your RV may be upgraded with an RV water filter.

The water that is flowing from your municipal water connection or aboard water tank flows through the filter in the finest designs before it travels through your water pipes and exits the faucet that you just opened.

These filters remove bigger particles from your water, but the better ones also get rid of germs and protozoa that are minuscule and may make you sick.

These filters purify your water using one of two fundamental filtering techniques.

Some people filter things physically, while others filter things chemically.

The most effective models actually combine these two filtering techniques.

The best method for eliminating big particles from your water is physical filtration.

This kind of filtration uses a device that resembles a sieve to trap dirt and other impurities as your water runs through it.

While some filters utilize a material resembling thin gauze to filter big particles, others use a kind of tiny textile membrane.

Chemical filtration purifies your water by using a specific chemical that is known to eradicate bacteria, protozoa, and other pathogens.

Just three of the numerous typical chemicals used in water filtration are iodine, chlorine, and algicide.

It is well known that this sort of filtration works better when it comes to clearing your water of possibly harmful microscopic organisms.

The ideal RV water filter will combine these two filtering techniques, as we briefly discussed above, to remove big sediments as well as neutralize tiny bacteria and protozoa.

#2. What’s The Lifespan Of An RV Water Filter?

Your choice of filter and how you apply it will determine the precise response to this inquiry.

The good news is that most filter makers openly promote how long their products will last when used often.

If you don’t use your filter every day, you may be able to increase its lifetime in specific circumstances.

While some filters only last three months, others might endure for up to a year.

It’s normally advised to change your filter every three to six months when using it often, even if you pick one with a lengthy lifetime.

In addition, your water filter may sometimes suffer from extended periods of inactivity.

If they aren’t used often, filters with a ceramic or charcoal element within, for instance, may dry up and break.

And you should never rely on a filter with a damaged element to perform the function for which you purchased it.

#3. How Do I Put In (Or Replace) A Water Filter For An RV?

Again, the precise procedure for installing or replacing an RV water filter may vary depending on the type you’ve chosen.

The easiest solution to this problem is to carefully read your user’s handbook and strictly adhere to the installation instructions when setting up or replacing an RV water filter.

Inline water filters have the easiest installation, so to speak.

These filters need only be fitted into the water hose that runs from your RV’s water input to the city water output.

However, you’ll need to install a canister-style water filter beneath your RV permanently if you buy one.

This kind of filter requires initial meticulous plumbing work since it also has to be linked to your RV’s water lines.

The first crucial step is to make sure the water is shut off to your rig and you take a little time to empty the pipes, regardless of whether you need to install or replace an inline or canister filter.

As soon as you start removing any hose fittings, this will assist you from getting any water in the compartments below your RV.

Next, check that your filters are correctly positioned so that water is flowing through them in the right direction.

The majority of filters will have obvious labels that help you distinguish between “input” and “output,” but if you’re still unsure, you should always refer to your user manual.

Connect all of the hoses and pipe fittings and tighten them after you’re certain that everything is correctly aligned.

But to ensure a watertight seal, be sure to wrap all fittings with plumber’s tape.

The filter may be mounted using the supplied hardware once everything has been connected and checked to ensure there are no leaks.

In order to guarantee that everything remains leak-free during the course of your filter, this helps to remove any weight from the filter and its connections.

#4. Is Hot Water Compatible With A Water Filter?

No, in a nutshell, is the response.

Using hot water with most of these filters may actually reverse the filtering process and cause pollutants to be discharged back into the water since they were not designed to handle hot water.

The best course of action is to contact the manufacturer first if you are unsure whether or not you can run hot water through a particular kind of water filter.

However, you can always correct it if you mistakenly put hot water through your filter by immediately running cold water through it for at least two minutes.

#5. How Is An RV Water Filter Cleaned?

The easiest method to extend the life of an RV water filter is to keep it clean.

In other words, cleaning your water filter more often will cut down on the need for filter replacement totally.

Backflushing an RV water filter is the first step in cleaning it.

In order to do this, pure water must be forced through the filter against its natural flow.

To backflush the filter and remove any material that has built within, you may need to manually reverse the filter’s flow or attach an external hose, depending on the kind of filter.

The easiest technique to create enough water pressure to effectively remove bigger bits of debris that may be caked within the filter while backflushing smaller filters is to use a syringe.

However, a typical garden hose should work for bigger filters.

If your filter has been dry for a while, you should wait a few minutes before backflushing it with water flowing in the typical direction.

This will moisten the parts and aid to start releasing any debris’ or bacteria’s grip on them.

You may also need to disassemble a ceramic filter in order to physically clean the filter.

Always use a brush with very gentle bristles to prevent scratching the ceramic filter while doing this.

Consulting your owner’s handbook is the best approach to be sure you’re using the appropriate kind of brush.

Some filter owners also like to clean their filters with chlorinated tap water.

When you flush the filter at the same time as doing this, it performs a better job of neutralizing any minute bacteria or protozoa that have gathered within the filter.

Use at least one gallon of chlorinated tap water to flush the filter if you use this approach.

before using it for drinking or washing dishes, pour another gallon of pure, clean water through the filter.

By doing this, you can make sure that your filter is no longer filled to the brim with chlorinated water.

You may also use a solution of tap water and bleach if, for whatever reason, you are unable to get chlorinated tap water.

If you want to use this method, be careful to use no more than eight drops of clear, unscented liquid bleach per gallon of fresh tap water.

After giving the mixture a good stir, let it rest for at least 30 minutes.

Then, using this bleach water solution, backflush your filter.

Before reconnecting the filter and running your drinking water through it once again, make sure you pour at least one more gallon of clean tap water (without bleach) through it.


I can speak from personal experience when I say that drinking water with a bad taste may be difficult.

This is particularly true if you live somewhere where the tap water is naturally delicious and very clean.

The good news is that if you live or travel in an RV, you don’t have to accept crappy water.

With the aid of the finest RV water filter, you’ll be able to more easily appreciate the flavor of whichever city water connection you choose to connect to.

But more significantly, it will protect you from any sicknesses or germs that could be in your water if it hasn’t been thoroughly filtered before it gets to your rig.

Investing in an RV water filter makes perfect sense if you just want to be safe and ensure that you always have access to clean water wherever you go.

Additionally, it’s a financial investment in both your own health and the health of everyone else who rides in your RV with you.
