10. Watts 520022 RV Duo Outside Water Filter

We first noticed how well this water filter suited RV and boat owners. But, of course, I’m talking about the garden hose fittings, which are an excellent feature for any RV owner searching for a water filter for their vehicle.

But, aside from how well-designed it is for use with RVs, the performance it gives isn’t bad either. This Watts RV water filter has been tested to remove 99 percent of cryptosporidium, giardia cysts, chlorine, sediment, and bad tastes and odors from your water.

The Watts comes with two filter cartridges and has a treatment capacity of 2.5 gallons per minute, which is more than adequate for any faucet and the great majority of showers. It is approved to remove 99.9% of cryptosporidium and giardia cysts and sediment and chlorine.

Unfortunately, the housing itself may be the package’s best feature. While it is incredibly sturdy and built to last, the rest of the bundle cannot be considered to be. The cartridges tend to leak, and the threaded connection points wear out quickly, making installation difficult, if not impossible.


  • two cartridges
  • a good flow of water
  • Effective


  • Cartridges leak, and the threading is poor.

11. Waterdrop TSU 0.01μm Under Sink RV Water Filter – Best Under-Sink Filter

If you simply need a water filter for one or two sinks in your RV, the Waterdrop TSU 0.01-Micron Filter System is an excellent choice.

It is designed to last up to two years and has one of the best filter components of any model on our list.

Before your water comes out of the tap, the 0.01-micron filter removes 99.99 percent of all sediments, bacteria, protozoa, and other pollutants.

  • Simple filter replacement
  • This filter has a two-year warranty.
  • Notifies you ahead of time when a filter replacement is required.
  • Facilitates installation and reduces leaking.


  • This filter is a tad costly for a filter that does not filter ALL of the water entering your RV.
  • Because this filter is installed under the sink, it will not protect your RV’s water lines from the buildup of sediments or potentially hazardous substances.

12. Waterdrop G2 RO Tankless Osmosis Water Filter – Best Reverse Osmosis

This filtration method is especially useful for long-term use because it eliminates the need to replace the filter every few months.

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 uses composite filters, which have a long shelf life and are intended to be updated every six months on average. Because this filtration system is built for family RVing with higher water usage levels, that filter replacement rate remains constant even at high usage rates.

The filter’s components are an activated carbon block and a polypropylene (PP) membrane. 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 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 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.


  • The filters in this system are meant to last at least six months.
  • 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.
  • Once the first installation is complete, replacement filters can be installed in about three seconds.


  • Due to reverse osmosis technology and space-saving design, this isn’t the cheapest RV water filter on the market.

13. Viqua S2Q-P/12VDC Silver Series – Best RV Ultraviolet (UV) Purification System

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. 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 anytime. But, of course, if you’re 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 and an alert to warn you if something is wrong before you drink the possibly contaminated water.

Ultraviolet systems eliminate bacteria and cysts from untreated water using chemicals or generating wastewater.

Suppose your RV travels frequently and takes you to off-the-grid locations where clean water is scarce. In that case, 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. However, because UV light alone will not improve water flavor, a carbon filter is recommended in front of the UV system.


  • Neutralizes 99.99 percent of hazardous germs in water Compact and slim design fits perfectly beneath the sink.
  • Electrical system with 12 volts DC for RV compatibility
  • A high-performance lamp will provide dependable results for the duration of its life.
  • Off-grid applications were in mind when designing this product.
  • The presence of an LED light indicates that the item is operational.
  • An alarm is built in to inform you whenever a lamp fails.
  • It has a short contact time and provides high flow rates.


  • If water is left in the chamber for an extended period, it can grow rather hot.
  • For best performance, a sediment prefilter is required. dubious

What exactly is an RV water filter?

RV water filters are filtration devices that remove sediment and other impurities from the water 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, premature failure, and damage to your plumbing and appliances.

If you have more particular water difficulties when traveling, various water filter alternatives help you. Untreated water sources can be made potable with the help of ultraviolet (UV) equipment. In addition, lead-removal filters can protect you from eating the heavy metal found in old 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 peace 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 worsening 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 to the current water system of your RV.

In the best designs, the water flowing from your municipal water connection or aboard a 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 others use chemical filtration. 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 known to remove bacteria, protozoa, and other impurities that might cause illness.

Iodine, chlorine, and algicide are just a few chemicals commonly employed in water filtering. When 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 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 a way to go.

One of the most common ways of water filtering is using 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 your water’s dirt, silt, and grit while 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 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. In addition, 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 to 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. Unfortunately, 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. In addition, you can use a UV purification system to clean water 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 free of practically all dissolved solids.

Reverse osmosis (RO) is one of the market’s most complete and powerful water filtering systems. 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. In addition, reverse osmosis systems necessitate a separate storage tank and a large wastewater booster pump. The water containing the rejected impurities is brine, 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 difficult because most campsites do not have drain hookups. However, a reverse osmosis system can offer you excellent water quality in your RV with devotion and adequate room.

Buyer’s guide

There is a lot to consider when selecting your next water filter. Likewise, there are a lot of features that affect whether or not a piece of equipment will operate well. In the next section, we’ll discuss some 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. First, many water filters can be used outside with the help of hose bib adapters.

You should filter the water from your garden hose for numerous reasons. First, the same chemicals you attempt to avoid can be hazardous to your plants. In addition, calcium buildup, which can be problematic while washing your automobile, can be eliminated 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 the output isn’t too low. Recreational vehicles frequently suffer from low water pressure, so most do not have extra power.


You may have also noticed that several 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 an RV water filter will last. 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. For example, when you shower, you use approximately 17 gallons of water. With a little bit of math, you can use statistics like these to create a more accurate chronology based on your behaviors. 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 termination of its life expectancy. In terms of hardware, brass is often good for preventing leaks and withstanding normal wear and tear.

Fortunately, housing materials may often be reused and 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 it may not be appropriate if you live in (or plan to visit) a region with a more harsh climate.

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. So, for example, you might come across a filter that claims to be able to eliminate 99.9 percent of pollutants. So naturally, 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 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 produces. 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 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, this should be more than enough for the vast majority of individuals. Remember that you just need the warranty to last for the filter’s life. 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 reasonable 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 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 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 the water entering 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. Ultimately, it all comes down to assessing the advantages and downsides and determining which strategy best meets your specific needs.


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 reverse the filtration process, allowing toxins back into the water.

If you have doubts about whether or not you can run hot water through a particular water filter model, 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. A carbon and sediment filter that removes dirt, grit, and chlorine from your water will provide the greatest flavor.

Do RV water filters get rid of chlorine?

The majority of RV water filters will eliminate chlorine. On the other hand, UV water filters 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, you can store them wet or dry. The sole need is that the location where the filters are stored be dark and clean.

Then, just remove the water from the canisters and replace the wet filters to keep the filters clean. 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.
