As an avid RVer, ensuring access to clean and safe drinking water is always a top priority for me. That’s why I decided to try the Camco TastePURE RV Water Filter, and I must say, it’s been a game-changer for my travels.

One of the standout features of the Camco TastePURE is its ease of use. Installing the filter is a breeze – you simply attach it to any standard hose, and you’re good to go. This makes it incredibly versatile for various applications beyond just the RV, such as gardening and pet care. The included flexible hose protector is a thoughtful addition, as it helps prevent kinks and reduces strain on the connections, ensuring longevity and consistent water flow.

The Camco TastePURE uses Granular Activated Carbon (GAC) and Kinetic Degradation Fluxion (KDF) technology to effectively reduce contaminants like chlorine, bad taste, odors, and sediment. This 20-micron filter ensures that even smaller particles are removed, making the water taste significantly better. I’ve noticed a marked improvement in the clarity and taste of the water since I started using this filter, which is a big relief given the often dubious water sources at various campsites.

Beyond just drinking water, the Camco TastePURE has been incredibly useful for other tasks. For example, using filtered water for cooking and washing has made a noticeable difference. The reduction in chlorine and sediment means fewer residues on dishes and less dryness on my skin. My plants are also thriving since they’re now getting clean, chlorine-free water.

The filter is designed to last for an entire camping season, which is typically around 3-4 months, depending on usage. For those who travel year-round, it’s recommended to replace the filter twice annually. Given its reasonable price point and the quality of filtration it provides, I find it to be a great value for money.

However, no product is without its flaws. Some users, including myself initially, noticed that the filter can have a slight plastic taste if not flushed properly before use. It’s recommended to run the water for about 30-60 seconds before consuming it. Additionally, there have been occasional reports of leaks due to a poor O-ring seal, but I found that ensuring a tight connection generally resolves this issue.


  • Easy Installation and Use: The filter is simple to attach to any standard hose, making it highly user-friendly and convenient for a variety of applications beyond just RV use.
  • Effective Filtration: Utilizes Granular Activated Carbon (GAC) and Kinetic Degradation Fluxion (KDF) technology to remove chlorine, bad taste, odors, and sediment. This results in significantly better tasting and clearer water.

  • Hose Protector Included: Comes with a flexible hose protector that helps prevent kinks and reduces strain on the connections, enhancing the filter’s durability.


  • Initial Taste and Odor: Some users report a plastic taste if the filter is not properly flushed before use. It’s recommended to run water through the filter for 30-60 seconds before consumption to avoid this issue.
  • Potential for Leaks: There have been occasional reports of leaks due to poor O-ring seals. Ensuring a tight connection can help mitigate this problem, but it remains a minor drawback.
  • Periodic Replacement Required: The filter needs to be replaced every camping season or every 3-4 months for optimal performance, which could be seen as a recurring cost for some users.
  • Compatibility Issues: It may not fit non-standard hose connections without an adapter, which can be an inconvenience if you’re using hoses of varying sizes.

Overall, the Camco TastePURE RV Water Filter is a reliable and effective solution for anyone looking to improve the quality of their water while on the road. Its ease of installation, superior filtration capabilities, and versatility make it an excellent choice for RV enthusiasts, campers, and even gardeners. Despite minor drawbacks, its benefits far outweigh any negatives, making it a staple in my RV setup.

  • Limited Warranty: The product comes with no manufacturer warranty, which might be a concern for those looking for guaranteed long-term performance and support.

My Guide to Finding the Best RV Water Filter

Hey there, fellow RV enthusiasts! I know how important it is to have clean, great-tasting water while you’re on the road. That’s why I’ve put together this handy guide to help you find the best RV water filtration system for your needs. Let’s dive in and explore all the essential aspects you should consider.


RV water filters come in a wide range of prices, and, believe me, price isn’t always the best indicator of quality. It’s tempting to go for the priciest option, thinking it must be the best, but that’s not always the case. My advice? If you’re sticking to established campsites with reliable water hookups, a lower-priced model with decent fittings will likely do the job just fine.

However, if you’re unsure about your travel destinations or are sensitive to chlorine and other contaminants, investing in a higher-performance model might be worth it. And don’t forget to think about how often you’ll be using your RV. If you’re a full-timer or frequent traveler, a longer-lasting filter might cost more upfront but save you money in the long run.

Ease of Use and Installation

Nobody wants to wrestle with a stubborn water filter, right? Make sure the filter you choose is easy to set up and straightforward when it comes time to change the cartridges. Look for models that fit standard hose fittings for hassle-free installation.

For added convenience, some filters come with built-in stands, or you can buy one separately. If you’re traveling a lot or using your RV in winter, durable and easy-to-connect fittings are a must, as you’ll be unhooking and re-hooking your filter often.

National Sanitation Foundation (NSF)

The NSF is a non-profit organization that sets standards for food and sanitary safety. When shopping for an RV water filter, look for NSF certification. For instance, an NSF/ANSI certification 42 means the filter effectively reduces aesthetic impurities like chlorine taste and odor. This certification gives you peace of mind that the filter does what it claims.

What’s in Your Water?

Traveling across different regions means encountering various water qualities. If you stick to well-regulated local campsites or keep your RV parked most of the time, you might only need a filter that handles specific impurities common to those areas.

Testing your water before purchasing a filter can help you tailor your choice to your needs. For city water hookups, reducing chlorine is often the goal. For more unpredictable sources, like well water, a multi-stage filtration system that reduces bacteria, viruses, and heavy metals is a safer bet.

Flow Rate – Amount of Water Needed

Consider your water usage when selecting a filter. If you’re filtering all the water coming into your RV, you’ll want a filter with a sufficient flow rate for activities like showering. On the other hand, if you use campsite showers, a smaller under-sink filter for drinking and cooking water might be all you need.

Micron Ratings

A micron is one-millionth of a meter, and RV water filters typically handle particles as small as five microns. Filters with smaller micron ratings trap more particles but clog up faster, so a two-stage system is often recommended. A filter rated below one micron will capture most bacteria and some viruses, but always consider bottled water or boiling when in doubt about a water source.

Filter Size

Larger filters allow more water to flow through at a faster rate and generally have a longer lifespan. If you’re a full-timer or use your RV frequently, opting for jumbo canisters over standard ones will let you filter more water more efficiently and reduce the frequency of replacements.

Water Filter Style

RV water filters come in two main styles: in-line and canister.

In-line Filters: Perfect for occasional RVers, these are great for improving taste and odor but not as effective with sediment. They’re affordable and convenient, making them a solid choice for removing chlorine taste and smell.

Canister Filters: These offer single, double, or triple filtration stages and are more customizable. They handle sediment well and have a longer lifespan due to their replaceable canisters. You can mix and match canisters to suit your specific filtration needs.

I hope this guide helps you find the perfect water filter for your RV adventures.

Types of RV Water Filtration Systems

Hey there, fellow RVers! Choosing the right water filtration system for your RV can be a bit overwhelming with all the options out there. Let’s break it down and take a look at some of the most popular types to help you decide which one suits your needs best.

Carbon Filters

If you’re like me and can’t stand the taste or smell of chlorine in your water, carbon filters are a game-changer. These are perfect for removing chlorine and chloramine, making your city water taste and smell much better.

There are two main types of carbon filters:

  • Basic Carbon Filters: These are great for improving taste and smell but have limited effectiveness.
  • Granulated Activated Carbon (GAC) Filters: These are a step up and do a better job of removing not just chlorine, but also sediment, pesticides, and metals.

Sediment Filters

Sediment filters are a must if you’re not always hooked up to a municipal water supply. They catch tiny particles of dirt and debris that can discolor your water and damage your RV’s plumbing. It’s best to install sediment filters before any other filters to improve overall efficacy and prevent clogging.

Ultraviolet (UV) Purification

UV purification systems are fantastic for killing microorganisms in your drinking water. These systems use ultraviolet rays to sterilize the water, ensuring you don’t get sick from bacteria or viruses. However, keep in mind that UV systems don’t remove odors, tastes, or particles—they just kill germs. They work best in combination with other filters and are great for purifying water already in your tank.

Reverse Osmosis (RO) Systems

For the cleanest, purest water, nothing beats a reverse osmosis system. These systems are like the ultimate in water filtration, removing almost all dissolved solids. Here’s how they work:

  1. Sediment Pre-Filter: Removes dirt and larger particles.
  2. RO Membrane: Removes salts and dissolved solids.
  3. Carbon Filter: Polishes the water, improving taste and smell.

Keep in mind that RO systems can be quite pricey and bulky. They also need a drain connection to dispose of the wastewater they produce. But if you have the budget and space in your RV, an RO system is a top-notch investment for the purest water.

Making the Right Choice for Your RV

Each type of filter has its strengths, and the best one for you depends on your specific needs and travel habits. For example:

  • If you frequent established campsites with city water, a carbon filter might be sufficient.
  • If you often boondock or use well water, a sediment filter followed by UV purification or an RO system could be the way to go.

Remember, you can always combine different types of filters to address all your water quality concerns.

FAQs About RV Water Filters

Why do I need an RV water filter?

An RV water filter ensures that the water you use for drinking, cooking, and showering is clean, safe, and free from contaminants like chlorine, sediment, bacteria, and heavy metals. It improves the taste and smell of your water, making your RV experience more enjoyable and healthier.

What types of RV water filters are available?

There are several types of RV water filters, including:

  • Carbon Filters: Great for removing chlorine and improving taste and smell.
  • Sediment Filters: Essential for filtering out dirt, sand, and other large particles.
  • UV Purification Systems: Use ultraviolet light to kill bacteria and viruses.
  • Reverse Osmosis Systems: Provide the highest level of filtration, removing almost all dissolved solids.
How often should I replace my RV water filter?

The replacement frequency depends on the type of filter and how often you use it. Generally, sediment and carbon filters should be replaced every 3 to 6 months. UV lamps typically need replacing annually, while reverse osmosis membranes can last 2 to 3 years with proper maintenance.

Can I install an RV water filter myself?

Yes, most RV water filters are designed for easy installation and come with clear instructions. You typically only need basic tools to get the job done. However, if you’re not comfortable doing it yourself, professional installation is always an option.

Do RV water filters affect water pressure?

Some filters can slightly reduce water pressure, especially if they are clogged or not designed for high flow rates. To minimize this, choose a filter with a suitable flow rate for your needs and replace it regularly.

What is a micron rating, and why is it important?

A micron rating indicates the size of particles a filter can remove. For example, a 5-micron filter can remove particles as small as 5 microns. The smaller the micron rating, the more particles the filter can trap. For most RV uses, a filter with a rating between 1 and 5 microns is ideal.

Are there any maintenance tips for RV water filters?

Regular maintenance ensures your filter works efficiently. Here are some tips:

  • Replace cartridges on schedule: Don’t wait until the water tastes or smells bad.
  • Clean sediment filters regularly: Rinse out accumulated debris to maintain flow rate.
  • Check for leaks: Ensure all fittings are secure and replace any damaged parts.
  • Sanitize your system: Periodically sanitize your entire water system to prevent bacterial growth.
Can I use my RV water filter in freezing temperatures?

Extreme cold can damage your water filter. If you’re camping in freezing conditions, use a heated hose and keep your filter inside the RV to prevent it from freezing. Alternatively, remove and store the filter during the winter months.

How do I choose the right RV water filter for my needs?

Consider the following factors:

  • Water Quality: Test your water to identify specific contaminants.
  • Usage: How often and where you use your RV will impact your needs.
  • Filter Type: Choose based on what you need to filter out (sediment, chlorine, bacteria, etc.).
  • Budget: Balance initial costs with long-term maintenance expenses.
Can I use multiple RV water filters together?

Absolutely! Using a combination of filters (e.g., sediment and carbon filters) can provide more comprehensive water purification. This multi-stage approach ensures your water is clean, safe, and pleasant to use.
