Whether you’re a full-time RVer or casually use your coach for adventure or outdoor camping, seriously, you always have to keep a strict check on your vehicle’s water filtration capabilities. For this purpose, your only need is to pick the very best water filter for RV.

But then, with a lot of technical mambos jumbos about water filtration for RVs available on the internet, you may get confused about which RV water filtration system you should pick or which one to leave. Along with the top 6 best RV water filters, I am patching a quite useful buying guide below to solve your “RV filter Equation” quickly.

Factors to Consider While Buying a Best Water Filter for RVs:

You’ll come across many technical specifications about the filter system, which you may not digest easily. We’ll be talking about the crucial points of considering an RV water filter in a much-simplified way.

Know Your Purpose:

Know Your Purpose
Purpose of water filter

This is where you may take a Wrong Turn in selecting a perfect RV water filter. What you have to do is, sit back, relax, and do all the math about what’s your purpose to achieve.
Basically, your purpose defines which type of RV filter you should opt for.
Whether you want to do whole RV water filtration or you are just okay with RV drinking water filter, it exclusively depends on your approach and varied circumstances. Contemplating this point will also save you from the unwanted future struggle of replacing and maintaining a filter.

Your Purpose VS. Filter System Type: 

Your Purpose VS. Filter System Type
Best filter system

Things become a little juicier here. You should know, your objective determines which filter system is going to be best for you. Technically, the real question here is whether “All of it, or some it.” Let’s simplify this term in 3 points:

  • Filtering Drinking water
  • Filtering Whole water supply
  • Filtering whole water supply + drinking water

Filtering Drinking Water and Type of Filter System:

Since your drinking water consumption is a minimal percentage of the whole RV water supply, you have plenty of options and choices here luckily. Also, in this approach of water filtration, the flow rate is something you can compromise on.

Filtering Drinking Water and Type of Filter System
Drink filtered water

So, the first option is Inline Filters that mostly get installed under the sink from where you take the water supply for drinking, cooking, and other purposes. These filters are helpful to avoid stagnation if you want to store water for a long while.
Other than this, One Canister-Cartridge System comes in for sediment removal, including Odor, Bad Taste, Smell, Cyst, etc.

This system also gets fitted under your sinks and being bacteriostatic in type; you can store your water for a long duration.

Filter Whole Water Supply and Type of Filters System:

This is the most common practice by the Bus owners. In this way, Inline filters are cheap, offhand to use, and a decent filtration setup. Yet, as these filters are small and built for low flow rates, many RVers don’t adopt this option.
As these devices are BASIC filtration setup, do expect a shorter life and limited capacity but decent sediment abilities for odor and taste improvement.

Other than this, Canister filters are a suitable alternative for decent cleaning and flow of water, saving a lot of your time. Adopting this way, you can also expect much-improved sediment removal, versatile customization, and a better life span.
Canister filters come in standard 1 canister, popular 2 canister system, and much advanced 3 canister filtration setup. Fortunately, the canister size is universal here, so you can embrace an excellent variety of cartridges, allowing you to achieve different filtration levels.

However, how these canister systems are different from each other, take a quick overview of their functionality.

Single-Canister System
Single-Canister System

Single-Canister System: One container or canister does all the cleaning job with the inclusion of multiple cartridges.

Dual-Canister System
Dual-Canister System

Dual-Canister System: Each canister does a specific part. One component should do the sediment removal while the other one should be responsible for carbon filtering.

Triple-Canister System
Triple-Canister System

Triple-Canister System: This system calls out for extreme sediment removal. For the first two Canister, the story is the same here, though, for 3rd canister, the job is for intense cleaning of water phosphate cleaning.

As the purpose is to filter the whole water supply, so these entire RV water filter systems will connect to the bus Hose and will procedure all the water before entering the vehicle water tank.

Cleaning Whole Supply + Drinking Water and Types of Filters:

This way, you should add filtration at two ends. Firstly, you should be going with the filtration of the whole water supply, then add an under sink filter for further improvement in drinking water. The under-sink filter will most possibly have the ceramic cartridge for bacterial contaminant removal.

Choose the Perfection Purification Technique:

To achieve a higher level of purity that everyone desires and dreams about, there are popular purification methodologies that you should study before adopting them.

  • UV sterilization: A very cost-effective solution for sterilization of micro-organisms. Yet, it can’t treat the spores and cyst reproduced by these microbes. Also, the flow rate is a decent call for drinking water supply.
    UV sterilization
    UV sterilization
  • RO – Reverse Osmosis: Most popular, widely used, and the cost-effective way all over the globe for removing all contaminants from water. The purification it gives is somewhat VERY NEAR to pure water. The only downside is, it also eliminates salts and minerals from water.
    RO - Reverse Osmosis
    RO – Reverse Osmosis
  • Distillation: A much higher level of setup to produce great purification targets. Yet, it lags a bit in the race for its energy-intensive consumption, expensive equipment, complicated installation.

The Micron Game:

This is something you should emphasize deeply. Micron is subject to the measurement of the particle’s size in your water intake. Lower the micron number, the higher will be the purity.

The Micron Game
1-5 micron filter

Usually, we take bacteria as the most dangerous thing in water, and water filters are standardized this way. Bacteria types range from 0.4 to 2 microns, and the 1-5 micron filter does almost the job.

These are some of the most crucial points you should care about while purchasing the best RV water filter. Apart from these, you can set cost, setup complexity, and such other criteria for your winning product.
