  • Integrated product design: The advanced integrated design of the electrical and water circuits reduces leakage. The airtight housing reduces noise, while the process of installing and replacing the filter is faster and more convenient than with other filters.

If you’re looking for a RO water filter, consider the Waterdrop G2 RO Water Filtration System.

This filter has a flow rate of 0.28 gallons per minute and a tankless design, which helps you conserve space and is also one of the reasons for its high flow rate.

It also makes use of composite filters, which have a long shelf life and are intended to be updated every six months or so on average.

Because this filtration system is built for family RVing with higher levels of water usage, that filter replacement rate remains constant even at high usage rates.

An activated carbon block and a polypropylene (PP) membrane are among the filter’s components.

The membrane and carbon block effectively filter out sediments, rust, excess chlorine, fluoride, and over 1,000 other pollutants.

Heavy metals, colloids, big particles, and other organic materials that should not be present in your water are examples of this.

While it is intended for installation under the sink in your RV, the tankless nature of this filtration system allows it to be around 70% smaller than most typical under-the-sink water filters.

Waterdrop built this filtering system with integrated electrical and water connections because it is intended to tuck out of the way beneath your sink.

This design decreases leakage while also lowering the risk of power outages if water spills from other sections of your RV.

The Waterdrop G2 may be installed in about 30 minutes if the precise instructions included with the filtration system are followed.

When the main body of the filtration system is installed, the filters simply twist and pull out when they need to be replaced.

So you can accomplish this in less than three seconds and return to filtering clean, pleasant drinking water.

  • This saves space under your sink while also increasing the flow rate of this system.
  • Reduces leaks and promotes safer use by lowering the likelihood of electrical shortages.

The Viqua S2Q-P is a unit particularly designed for RV applications, having been crafted with RV electrical system standards in mind. This RV water filter shields you and your passengers from microorganisms found in untreated water.

The Viqua S2Q-P operates at 12 volts, although many UV purifying systems operate at 120 volts or more. Most RVs have three electrical systems: a 12 volt automobile system, a 120 volt AC coach system, and a 12 volt DC coach system.

The 120 volt AC coach operates only when the RV is attached to a 120 volt electrical supply at a campsite, but the 12 volt DC system can operate at any time. If you’re going to be treating potentially contaminated water, you’re probably not going to be near a campground.

The unit’s sleek, lightweight, and compact form fits perfectly beneath your sink or unobtrusively behind your storage tank in your coach. It includes a green LED light to ensure the system is working properly, as well as an alert to warn you if something is wrong before you drink the possibly harmful water.

Ultraviolet systems eliminate bacteria and cysts from untreated water sources without the use of any chemicals or the generation of any wastewater.

If your RV travels frequently take you to off-the-grid locations where clean water is scarce, a UV purification system assures that any bacteria lurking in the water is rendered inactive. A UV system in your RV keeps you and your fellow passengers safe and healthy.

The Viqua S2Q-P can also filter water from untreated sources such as precipitation or surface water such as lakes and streams (though if you are drawing water from a lake or stream, it is always judicious to have a water analysis performed first.) UV systems operate best when combined with a sediment filter, as sediment particles such as rust and sand can encase germs and shield them from ultraviolet radiation.

The Viqua S2Q-P comes with a sediment filter kit that may be installed in front of the UV lamp to improve overall system performance. Because UV light alone will not improve the flavor of water, a carbon filter placed in front of the UV system is recommended.

What exactly is an RV water filter?

RV water filters are filtration devices that remove sediment and other impurities from the water that is pumped into your RV. RV water filters improve the overall flavor of your vehicle’s water supply by lowering chlorine and removing sediment, preventing clogging and premature failure and damage to your plumbing and appliances.

If you have more particular water difficulties when traveling, there are a range of water filter alternatives to help you. Untreated water sources can be made potable with the help of ultraviolet (UV) equipment. Lead-removal filters can keep you safe from eating the heavy metal found in ancient and corroded pipelines.

An RV water filter is also a more cost-effective and environmentally responsible alternative to purchasing bottled water. Your RV water filtration system can be simply tailored to your specific RV lifestyle, budget, and coach size. Whether you are a full-time RVer or planning a summer vacation in your RV, a water filter will improve your experience.

What are the benefits of using an RV water filter?

  • Clean water: Don’t let bad odors and dirty water ruin your vacation. You can’t predict the quality of water you’ll encounter on the road, so make the most of it by outfitting your RV with a water filter. You’ll never have to worry about showering with discolored water or drinking polluted water again. A simple RV water filter can provide you with piece of mind and improve your overall experience.
  • Keeps your RV’s plumbing from becoming clogged: Sediment buildup is detrimental to the plumbing in your RV. Sediment buildup can choke pipes and cause plumbing problems. It also contaminates your water storage tank, necessitating more frequent cleanings and resulting in worse water quality. Installing a simple inline or canister filter prevents silt from entering your RV system in the first place, saving you the headache of pricey repairs.
  • Flexible options: Regardless of the level of water filtration desired, the water filtration industry has created creative solutions for RVers. There is a solution to your water quality concerns, from installing reverse osmosis membrane technology beneath the sink to simple hydrant hook-ups to eradicate that chlorine taste. Because no single system is ideal for everyone, examining your RV habits and researching available solutions can assist you in finding the ideal match.
  • Environmentally friendly alternative: If you’ve been relying on bottled water on the road, you no longer need to be concerned about all that plastic ending up in the landfill. Water filters are significantly more convenient than carting cartons of bottled water and, in the long run, far less expensive. The cost of bottled water adds up. Furthermore, using a filter eliminates the need to remember to purchase water ahead of time.

What is the function of an rv water filter?

An RV water filter is intended to be fitted in the current water system of your RV.

In the best designs, the water flowing from your municipal water connection or aboard water tank travels through the filter before passing through your water pipes and out the faucet you’ve just opened.

These filters remove bigger sediments from your water, but the finest ones also remove microscopic protozoa and bacteria, which can cause illness.

These filters clean your water using one of two fundamental filtration technologies.

Physical filtration is used by some, whereas chemical filtration is used by others. Both of these filtration approaches are used in the top models.

Filtration by physical means

Physical filtration is the most effective method for eliminating big particles from water.

This filtration method employs a sieve-like mechanism that collects dirt and particles as your water travels through it.

Some filters employ a fine textile membrane to filter big particles, while others use a substance similar to thin gauze.

Filtration by chemicals

Chemical filtration disinfects your water by using a chemical that is known to remove bacteria, protozoa, and other impurities that might cause illness.

Iodine, chlorine, and algicide are just a few of the many chemicals commonly employed in water filtering.

When it comes to removing potentially dangerous tiny organisms from your water, this sort of filtration is recognized to be superior.

As we briefly indicated above, the finest RV water filter will use both of these filtration technologies to remove large sediments while also neutralizing tiny germs and protozoa.

RV Water Filtration Types

The filtration system you choose for your RV will be determined by how frequently you use it, the impurities in the water you have accessible, and the level of water quality you prefer. Understanding what each filter option provides will assist you in deciding which system to purchase.

Filters made of carbon

If you want to improve the taste and odor of your water by removing chlorine and chloramines, a carbon filter is the way to go.

One of the most common ways of water filtering is the use of a carbon filter. Carbon filters are well-known for their capacity to restore the fresh taste of water by removing chlorine and chloramines.

As a disinfectant, chlorine is added to municipal water sources. Through a process known as oxidation, chlorine penetrates the cell walls of dangerous bacteria and destroys them.

Unfortunately, chlorinated water has a harsh chemical taste and an unpleasant odor. Carbon efficiently eliminates chlorine through a process known as adsorption. Contaminants attach to the surface of the carbon block like Velcro when the filter processes the water.

Carbon can help remove pesticides, herbicides, and other VOCs (volatile organic compounds) from water. A carbon filter is ideal for your RV if you want to improve the taste and smell of water and your water source is free of pathogenic microorganisms and heavy sediment.

Filters for Sediment

A sediment filter eliminates dirt, silt, and grit from your water while also protecting your RV’s plumbing and extending the life of your other filters.

If you’re dealing with dirty or debris-filled water, a sediment filter is a must-have protection for both your water and your RV. Sediment can render your water a murky brown or yellow appearance and give it a foul, unappealing taste.

Sediment can also damage your RV’s plumbing and appliances. Dirt and debris can clog your RV’s plumbing and cause damage to your toilet, shower, and faucets. Sediment buildup can limit water pressure and result in costly, avoidable repair charges. Sediment also significantly lowers the effectiveness of various types of water filtration systems. When exposed to heavy sediment, carbon quickly depletes, and dirt and debris hinder UV radiation from safely cleaning your water.

It is strongly advised that all RV owners utilize a sediment filter for their water. A sediment filter is required if you connect your RV to anything other than ordinary city water. Investing in sediment filtration ensures the health and longevity of your RV and other filters.

Purification using Ultraviolet Light

UV systems are ideal for water that is microbiologically dangerous due to the presence of bacteria, cysts, and viruses.

By exposing live organisms like bacteria to germicidal ultraviolet wavelengths, ultraviolet purification (UV) neutralizes them. These germs can be pathogenic, causing you and anybody else in your RV to contract waterborne infections.

UV lamps use light to scramble bacteria’s genetic coding, rendering them unable to reproduce in water. This keeps them from contaminating your water and transmitting sickness. If you intend to visit areas with questionable water quality, a UV system will keep you safe during your investigations.

While UV sterilizes the water, it does not improve taste, therefore use it in conjunction with another RV water filter system to maximize the water quality in your RV. You can use a UV purification system to clean water that has been sitting dormant in your storage tank or to ensure that no hazardous bacteria reach your water from a well or untreated water source.

Reverse Osmosis

A reverse osmosis system is suitable for anyone who wants high quality water that is free of practically all dissolved solids.

Reverse osmosis (RO) is one of the most complete and powerful water filtering systems on the market. Water is forced through a semipermeable membrane constructed of microscopic pores, which removes dissolved salts and particles from the water. A sediment prefilter removes material from the water before it travels through the membrane, and a carbon postfilter polishes the flavor of the water after it has passed through the process. While extremely effective, reverse osmosis is not a feasible option for the majority of RVers.

Though RO systems are becoming more popular among some RV owners, the quantity of space required by a system is inconvenient for most coaches. Reverse osmosis systems necessitate a separate storage tank as well as a large amount of wastewater booster pump. The water containing the rejected impurities is referred to as brine, and it is flushed out of the system and into the drain.

Without a permeate pump to reduce waste, around 80% of the water handled by RO units will become brine. This might be a difficult operation because most campsites do not have drain hookups. However, with devotion and adequate room, a reverse osmosis system can offer you with excellent water quality in your RV.

Buyer’s guide

There is a lot to consider when selecting your next water filter. There are a lot of features that affect whether or not a piece of equipment will operate well. In the next section, we’ll break down some of those factors to help you make a more informed purchasing decision.


Obviously, the objective of today’s tutorial is to showcase water filters for RVs. However, you might get more bang for your buck by purchasing something that can serve two functions. Many water filters can be used outside with the help of hose bib adapters.

There are numerous reasons why you should filter the water from your garden hose. For starters, the same chemicals you’re attempting to avoid can be hazardous to your plants. Calcium buildup, which can be problematic while washing your automobile, can be eliminated by using a good water filter.

Investing in something adaptable will boost the functionality of your filter and may be quite beneficial in the long term.

Water pressure

Unfortunately, water filters frequently reduce water pressure in your RV. However, the extent to which this is true can vary greatly. Some units even state how much water they can produce. This figure is referred to as the “gallons per minute” output.

While you may not know exactly how many gallons per minute you require, there are a few indicators to keep in mind. The usual shower, for example, uses about 2-3 gallons per minute. As a result, you are unlikely to require anything that surpasses this output ratio.

In any event, you’ll want to ensure that the output isn’t too low. Recreational vehicles frequently suffer from low water pressure, which means that most do not have extra power.


You may have also noticed that several of the alternatives on our list had more than one filter. The obvious advantage is that you get a lot greater mileage. A two-pack is more expensive, but it also extends the life of your total purchase, perhaps saving you money in the long term.

Expected life expectancy

Several factors influence how long a water filter will survive. Obviously, personal use is the most important consideration. The more frequently you use your filter, the sooner you will need to replace it. Unfortunately, this is usually only discovered after you’ve noticed some foul water pouring out of your faucet.

Most manufacturers include suggestions for how frequently you should replace your filter. These ratings often range from three months to a year. However, while these estimates may be correct in the house, they are most certainly incorrect in the RV, where you are most likely consuming significantly less water.

As a result, some businesses instead state the number of gallons of water the filter can process before needing to be replaced. When you take a shower, for example, you use approximately 17 gallons of water. You can use statistics like these to create a more accurate chronology based on your behaviors with a little bit of math. Filters with a longer life expectancy typically cost more, but they save you money in the long run.

Hardware and housing

The filtration cartridge isn’t the only piece of equipment you’ll have to deal with. There’s also the housing and the attachment hardware, both of which can have a significant impact on the effectiveness of your product.

Choose a filter with a strong plastic housing to ensure that it will endure the term of its life expectancy. In terms of hardware, brass is often good for preventing leaks and withstanding normal wear and tear.

Housing materials, fortunately, may often be reused and may even be compatible with filters from other manufacturers!


Some water filters thrive only when used at specific temperatures. This range is usually vast, although it may have limitations. For example, you might discover that the filter you’re thinking about works best between 30 and 100 degrees Fahrenheit.

Most people will be fine with this, but if you live in (or plan to visit) a region with a more harsh climate, it may not be appropriate.

Treatments you desire

Not all water filters have the same targes. As a result, you should discover what the filter in question is capable of.

Here is a list of common pollutants found worldwide, but perhaps notably at campsites:

  • Sedimentation (sand, dirt, etc.)
  • Chlorine
  • Rust, Lead, and Foul Odor

Most filters specify what they can handle and how effective they are. For example, you might come across a filter that claims to be able to eliminate 99.9 percent of pollutants. Obviously, the better off you will be if your filter is effective.

Water Tension

Some filters will also state that they require a specified pressure (PSI) rating in order to be successfully used. For example, you may discover that the range must remain between 30 and 60 PSI.

Typically, the amount listed by the manufacturer will be close to what your plumbing system is presently producing. For safety, water pressure is already regulated (too high, or too low, and you start to encounter quality problems).

To be safe, you should check to see whether the filter has any extra PSI requirements. If this occurs, you will need to acquire a specific regulator.


Water filters do occasionally malfunction. When they do, you’ll be glad you bought something with a decent warranty.

Many of the products on our list today had warranties ranging from one to three years. Fortunately, for the vast majority of individuals, this should be more than enough. Remember that you just need the warranty to last for the life of the filter. If you only expect your filter to last 6 months, any filter that lasts longer than that would suffice.


Unfortunately, the ordinary water filter is somewhat expensive. More money often buys a more sturdy housing, a longer lifespan, and, of course, a very effective filtration mechanism. As you try to come up with a suitable budget for this purchase, keep in mind that you should be able to obtain a functional unit with all the necessary accessories for $40 or more.

There are still nice things for less than this, but with that as a starting point, you should be able to select predominantly high-quality products.


Some water filters are connected to the line that enters your RV’s water tank (also known as inline), while others must be put under the sink for filtration of drinking water alone. If you require filtered water for your entire RV—including showering—you’ll need a unit that also filters the water entering the storage tank. You can use multiple filters to eliminate contaminants from the container before filtering the drinking water at the tap.

Should I filter all of the water used in the RV or just the drinking water?

As said in the previous section, it all depends on what you want from your RV water filter. Some people purify only the water they consume, while others filter all of the water that enters their RV. It all comes down to personal preference.

In my personal experience, I would always choose to filter all of the water that enters my RV. It’s more out of paranoia about my health than anything else, but it has been shown to improve skin, nail, and hair health.

As a result, I’ve always believed that filtering all of my water was the best option. However, getting a system that will do so will cost you a little extra money. In the end, it all comes down to assessing the advantages and downsides and determining which strategy best meets your specific needs.

What is the best way to clean an rv water filter?

The easiest method to extend the life of your RV water filter is to keep it clean. In other words, cleaning your water filter more frequently reduces the frequency with which you need to replace it totally.

Backflushing an RV water filter is the first step in cleaning it. This entails passing clean water through the filter in the opposite direction it normally runs.

Depending on the filter, you may need to manually reverse the flow of the filter or attach an external hose to backflush it and remove any material that has gathered inside.

For smaller filters, using a syringe for the backflush operation is recommended since it is the best way to generate enough water pressure to remove larger bits of material that may be caked inside the filter. However, for larger filters, a normal garden hose should suffice.

If your filter has been dry for a while, you should let water flow through it normally for several minutes before backflushing it.

This will moisten the components and aid to loosen the grip that any bacteria or debris has on them.

If you have a ceramic filter, you may need to disassemble it and manually brush the filter clean.

To avoid damaging the ceramic filter, always use a brush with very soft bristles when doing this.

Consult your owner’s manual to ensure that you’re using the correct sort of brush.

Some filter owners choose to clean their filters with chlorinated tap water. This is more effective at neutralizing any minute bacteria or protozoa that have gathered inside the filter while also flushing it.

If you employ this procedure, make sure to flush the filter with at least one gallon of chlorinated tap water.

Then, before using it for drinking or dishwashing, put another gallon of regular clean water through the filter.

This allows you to guarantee that there is no excess chlorinated water inside your filter.

If you can’t find chlorinated tap water, you can make your own with a mixture of tap water and bleach.

If you choose this option, make sure to use no more than eight drops of unscented and clear liquid bleach per gallon of clean tap water.

Then thoroughly whisk the mixture and set it aside for at least thirty minutes.

Then, using this bleach water solution, backflush your filter. Before reconnecting your filter and running your drinking water through it again, make sure you pour at least another gallon of clean tap water (without bleach) through it.

How long will an rv water filter last?

The exact answer will depend on the filter you select and how you use it.

The good news is that most filter manufacturers publicly mention how long their filters will last if used on a regular basis.

If you do not use your filter every day, you may be able to extend its lifespan in some circumstances.

Some filters have a three-month lifespan while others have a one-year lifespan.

Even if you choose a filter with a long lifespan, it is generally suggested that you replace it every three to six months if you use it frequently.

Furthermore, long periods of inactivity might have a severe impact on your water filter.

Filters containing charcoal or ceramic elements, for example, might dry out and shatter if not utilized on a regular basis.

A filter with a fractured element should never be trusted to fulfill the purpose for which it was purchased.

How do i install (or replace) my rv water filter?

The precise technique of installing or replacing an RV water filter will, once again, depend on the model you’ve purchased.

When installing or replacing an RV water filter, the simplest option is to carefully review your user’s handbook and follow the installation instructions to the letter.

Inline water filters, on the other hand, are the simplest to install.

These filters are simply fitted into your water hose between the city water output and your RV’s water input.

A canister-style water filter, on the other hand, will necessitate a more permanent installation under your RV.

This type of filter must also be linked to your RV’s water lines, which may necessitate a little more cautious plumbing work at first.

Whether you need to install or replace an inline or canister filter, the first step is to ensure sure the water to your rig is switched off and that you drain the pipes.

When you begin loosening any hose fittings, this will help you avoid getting water in your RV’s underside compartments.

Following that, ensure that your filters are properly positioned so that water passes through them in the proper direction.

Most filters will be clearly labeled to assist you distinguish between ‘input’ and ‘output,’ but you should always reference your user manual if you are unsure.

Once you’re certain that everything is properly aligned, connect and tighten all hoses and pipe fittings.

However, in order to ensure a watertight seal, wrap all fittings with plumber’s tape.

After you’ve connected everything and tested it to ensure there are no leaks, you may install the filter with the accompanying hardware.

This relieves some of the strain on the filter and its connections, ensuring that everything remains leak-free for the duration of the filter’s life.


Do you have any further questions concerning these water filters? We’re not surprised, which is why we’re still here! Before we proceed, let’s go over some of the most often asked questions concerning RV water filters and how to care for them.

Is it possible to use a water filter for hot water?

In a nutshell, the answer is no. Most of these filters aren’t designed to handle hot water, and using them with it can actually reverse the filtration process, allowing toxins back into the water.
If you have any doubts regarding whether or not you can run hot water through a particular model of water filter, the best line of action is to contact the manufacturer.
If you do mistakenly pass hot water through your filter, you can always rectify it by immediately running cold water through it for at least two minutes.

What is the best water filter in terms of taste?

The answer to this question is highly subjective. In general, a carbon and sediment filter that removes dirt, grit, and chlorine from the water you drink will provide the greatest flavor.

Do RV water filters get rid of chlorine?

The majority of RV water filters will eliminate chlorine. UV water filters, on the other hand, do not, so carefully read the specifications of the water filtration system before purchasing.

How do you keep RV water filters stored?

Because they are not prone to stagnation or when water does not move for an extended period of time, you can store them wet or dry. The sole need is that the location where the filters are stored be dark and clean. To maintain the wet filters clean, just remove the water from the canisters and replace the wet filters. If you have CDB-KDF filters, keep them submerged in water.

Where is my RV’s water filter?

Some water filters are connected to the hose at the entrance of your RV’s tank. Others may be installed beneath the sink. It’s also possible that your RV has a filter in the tank and another beneath the sink.

Do RV water filters remove chlorine?

The majority of RV water filters will eliminate chlorine. UV water filters, on the other hand, do not, so carefully read the specifications of the water filtration system before purchasing.
