Finding Quality Water Sources for RVs

When you visit a State or National Park campground, a private RV campground or even a Harvest Host location, they typically have a water source for your RV to hook into to have a direct water flow to your interior faucets. In traveling around the country, I know from personal experience and research that not all water sources are equal. Water quality varies a bit and, in some places, can even be toxic.

How to Choose the Best RV Water Filter for You

When searching for the best RV water filters, it’s essential to consider factors such as filtration efficiency, filter lifespan, and ease of installation. Look for filters capable of removing a wide range of contaminants with a long-lasting filter cartridge or replaceable elements. Additionally, opt for easy installation and maintenance filters, as this will save you time and effort on the road. Some popular options for top RV water filters include brands like Camco, Culligan, and AquaCrest, known for their quality and reliability. 

Investing in the best RV water filter for your needs ensures that your water supply remains clean and refreshing throughout your RV adventures, promoting a healthier and more enjoyable travel experience.

Features

Next, I delved into the features offered by each RV water filter. Every traveler’s needs are unique, and so are the features required in a water filter. I sought filters that offered multiple stages of filtration, as this helps to eliminate a broader range of contaminants. UV sterilization features were also a plus, as they provide an extra layer of protection against harmful bacteria and viruses. An essential consideration for me was the filter’s flow rate, as some models may have slower filtration speeds, which can be frustrating when you need water quickly. I also looked for filters with easy installation and maintenance processes, as I prefer hassle-free solutions during my travels.

Potential Negatives

While evaluating the products, I made sure to take note of any potential negatives associated with each RV water filter. This included considering any limitations in terms of filtration capacity, filter lifespan, or compatibility with various RV setups. Some filters might require more frequent filter replacements, adding to ongoing costs. Additionally, I weighed the physical size of the filters to ensure they would fit comfortably in my RV’s designated storage area. Understanding the limitations of each product allowed me to make informed decisions, avoiding potential disappointments down the road.

Frequently Asked Questions

Are RV water filters necessary?

Water pipes degrade over time since water quality varies across the country and in different RV parks and campgrounds. Hence, you need to know the water quality at any campground you visit.

Should you drink the water directly from the tap?

Though you can drink tap water at RV campsites, over 30% RVers polled used some filter before they drank the water in their RV.

Where do you attach an RV water filter?

It is recommended that Inline RV water filters should be connected closest to the city water inlet. Most inline water filters come with a hose attachment to attach the filter to the channel.

Micron ratings are the size of the openings in the filter. The larger the number, the more it allows through.
