Top RV Water Filters 2018 – How to choose the best RV water filter systems for your Motorhome, Trailer, or Camper

While traveling or living in your motorhome, trailer, camper, or other recreational vehicle (RV), you may find yourself in situations where the available water is unsuitable for drinking or using. We’re here to help you choose the best RV water filter for your water needs.

Water may contain sediment, dirt, rust, and minerals which affect the flavour, look, and smell of the water. Water may also contain dangerous substances, contaminants, and bacteria which can cause serious illness. Additionally, RV water tanks can pose bacterial risks to water safety if the tanks are not adequately cleaned and circulated.

For your health, ensure the water you are using and drinking in your RV is safe. The easiest and best way to do that is with an RV water filter. There are various RV water filter systems available in the marketplace, so we want to make it easy for you to find the best RV water filter for your needs. There are several considerations you should take into consideration prior to buying a RV water filter. Please give us a call on (800) 817-6306 to discuss the best RV water filter for your motorhome, trailer, or camper.

What’s wrong with the water?

Sediment in water

Sediment is a natural occurring mineral that causes turbid, cloudy, or dirty water. It’s mostly an inconvenience, but sediment in your water can eventually wear out your equipment leading to it needing to be replaced. If your water is usually dirty or has sediment, you will want to have a RV inline water filter.

Chlorine in water

Like we said earlier, most campgrounds provide chlorinated city water. Chlorine in water is not a viable method to treat all contaminants and pollution. Chlorine in water causes heavy metals, like lead, to leach in the water when it makes contact with the aging alloy pipes which may exist in campgrounds. Chlorine in tap water isn’t the only concern: there is also the risk of inhaling the chloroform gas that’s created in the steam vapor from the shower. Not to mention, chlorine itself has a highly unpleasant taste and odor. Read more about the dangers of chlorine in water. A RV water filter system that includes a carbon filter will remove the taste and smell of chlorine from the water you use in their RV.

Minerals in water

Some minerals in water can be beneficial for health of course, but certain minerals or too much of a mineral can be troublesome. If you’re worried about mineral traces in the water- in this case your water will have a murky color- then you might need additional purification to address your problem. Mineral deposits are different than the pollutants that cause bad taste or have an odd smell.

Bacteria in water

Bacteria issues in water require filtration that’s effective at destroying the harmful organisms. Bacteria that can be present in water include: total coliform, fecal coliform, E. coli, campylobacter jejuni, parasites (cryptosporidium and giardia), hepatitis A, legionella pneumophila, and salmonella. Drinking or coming in contact with water contaminated with such bacteria can cause a variety of illnesses. Most times, exposure to such bacteria may cause minor gastrointestinal discomfort but it can lead to serious conditions or death especially in the very young, old, or those with weakened immune systems. We always recommend using a RV water filter that is capable of removing bacteria.

Other contaminants in water

There is a whole list of other contaminants and chemicals that could be present in your water including: Asbestos, Aluminum, Arsenic, Barium, Bicarbonate, Borate, Bromide, Cadmium, Calcium, Chloramine, Chloride, , Chromate, Chromium, Copper, Cyanide, Detergent, Ferrocyanide, Flouride, Herbicides, Insectecides, Lead, Magnesium, Manganese, Mercury, Nickel, Nitrate, PCBs, Perchlorate, Phosphate, Potassium, Radium, Selenium, Silicate, Silver, Sodium, Spores, Strontium, Sulfate, Thiosulfate, THMs (trihalomethanes), VOCs (volatile organic chemicals), Zinc, and more.

How much water should I filter?

There’s two options here: you can filter all the water coming into your RV, or some of it (such as just the drinking water).

To filter all the water, you will need a filter that is attached to the hose and filters all the water going into your RV holding tank. You may want to consider an RV inline water filter. RV inline water filters screw directly on the water outlet and then attach to the hose which runs to the camper.

RV inline water filters that combine carbon filtration and sediment removal are the best RV water filter systems. Be aware that when picking a RV inline water filter some systems may provide adequate odor and taste removal, but they have limited sediment removal. This means your water may still be cloudy.

Other drawbacks of RV inline water filters are that they are small in size (after all, they have to attach to the hose), have a limited flow rate, and also a short life span due to their small size. A RV inline water filter is okay for RVers who do not use their rig too often, but if you are a full time RVer a water filter canister system is your best bet.

A water filter canister system might also be called a point of entry water filter because, like the name suggests, it filters water at the point before it enters your RV. This type of RV water filter will provide a longer life span, better flow, and increased water filtration capabilities. A canister water filter system can be customized for special purposes and water conditions, and there are many filter cartridges available.

You can opt for a one, dual, or even triple cartridge system depending on your water filtration goals. You can also decide to go with standard size canisters (they hold roughly 10″ water filters) or jumbo canisters for even larger filters. The best RV water filters for full time RVers are the filtration systems with the larger canisters because they have better flow rate and will require less cartridge changes saving you time and money.

If you install a one cartridge system, make sure the filter performs multiple functions. If you install a dual or triple cartridge system, each water filter cartridge can have a specific task. For example, the individual filter may focus on sediment removal or taste and odor improvement.

Sediment filters are what you may need if your issue involves mineral deposits. They work by stopping the destruction of your plumbing system by capturing the murky deposits before they’re carried through your RV. For issues with the smell and taste of your water a sediment filter won’t provide the purification required to remove these smaller pollutants. Carbon filters are utilized to draw in and absorb these smaller particles and can be found in block and granule type, but the block style is recommended for the exceptional performance.

A good dual cartridge system would consist of a 1 micron sediment cartridge paired with a carbon block water filter cartridge for taste and odor. A triple cartridge system might have a 5 micron sediment filter, followed by a 1 micron filter, then the third, a carbon block water filter. There is lots of room for customizing a cartridge water filtration system.

To filter some of the water in your RV, you’ll want a point of use water filter. This type of water filter will filter the water where you want to use it. For example, an under sink water filter will filter the water for the specific faucet it is connected to.

If your water has dirt, particles, or sediment (or you suspect it’s unsafe), you will need to filter all of your water. It’s also important to point out that most campgrounds provide chlorinated city water so it may be necessary to still treat the water to remove that unpleasant chlorine taste and odor. Some campgrounds have well water which can have a wide variety of contaminants. (We’ll discuss how to treat chlorine and other contaminants in the next section).

What size RV water filter do you need?

An important consideration in determining the best RV water filter for your situation is assessing your current water pressure. The bigger a filter is, the more powerful the water flow. If your water flow is too powerful it might damage the plumbing system, but if it is too feeble then you will not have sufficient water pressure for showers and doing the dishes.

This all means that in some instances you may need a smaller filter, and in others a bigger filter, dependant upon your water pressure regulation.

RV water filters (and water filters in general) are given micron ratings. The micron rating refers to how small of particles the filter will let pass. The smaller the micron or submicron rating, the more pollutants that are being filtered out.

Another issue that might arise will be that after the purification process the filter may become clogged with contaminants which can significantly reduce water flow as well. So in cases of severe water pollution, a bigger filtration system may be your best option.

Other considerations to enjoy the best water possible in your RV

Clean and Sanitize your RV Fresh Water Tank

It’s really important that you clean and sanitize your RV fresh water tanks regularly to prevent stagnation. For those who are RVing full time and frequently emptying and filling their tank, you don’t need not worry about stagnation too much. However, you still should sanitize your fresh water tanks from time to time to prevent bacteria build up.

If you only use your RV part time or it is left abandoned for months at a time, tank maintenance is a must with a periodic cleaning to keep your tanks clean and sanitized.

Water Pressure and Flow in RV Water Filters

Water flow rate is the volume of water delivered over a unit of time. It’s typically measured as gallons per minute (GPM). Water pressure is the measure of force that gets the water through your pipes. Pressure and flow are connected: the better the water pressure, the better the flow rate.

RV plumbing systems are usually set between 60 and 85 psi. (The plumbing in your home operates at 60 psi). If the pressure is set at 100 psi in your RV, your plumbing system could burst. It’s important to install a pressure regulator so you don’t burst your pipes.

Anything that blocks or reduces the size of your pipes will cause a problem with flow. The most frequent causes of a disruption in flow rate include:

  • Collapsed or kinked hoses – check your hose first!
  • Pressure regulators are a sensible investment, but sometimes you do get what you pay for: the cheaper the pressure regulator, the higher the chances that your flow will be restricted
  • Clogged filters
  • Fixtures and fittings – small pipes and other fittings may be the cause of your flow problems
