12 Best RV Water Filters Review
1. Camco Tastepure RV Water Filter – Advanced 6-Step Patent-Protected Filtration
The Camco Tastepure RV Water Filter utilizes an advanced, patent-protected 6-step Hex-Flow Technology to deliver exceptionally clean and fresh-tasting water. This inline filter is a camping essential for any RV owner or boater looking for reliable, easy-to-install filtration. It’s effective at reducing bad tastes, odors, chlorine, and sediment, ensuring a better drinking experience.

How to Choose Best RV Water Filters
Choosing the right set of Best RV Water Filters is vital for health and appliance longevity. An RV water filter’s main job is to remove harmful contaminants, improve the water’s taste and smell, and prevent sediment from damaging your RV’s pipes, faucet heads, and water pump. Because you’ll encounter wildly different water sources, from high-chlorine city water to sediment-heavy well water, a good filter acts as your first line of defense. Focusing on the right features ensures you get the most effective and hassle-free solution.
Micron Rating (Particle Size Filtration)
The micron rating indicates the size of particles the filter can remove. Inline filters typically use a 20-micron rating, which is fine for basic sediment and prolonging the life of your RV plumbing. For drinking water, aim for a system with a 5-micron pre-filter and a 0.5-micron or smaller carbon block. A micron rating of 0.2 or less (as seen in the Clearsource and Glacier Fresh systems) is considered necessary to remove bacteria and small cysts, providing the highest level of water safety.
Filter Media (GAC, KDF, and Carbon Block)
The filtering material is crucial for aesthetics and chemical removal. Granular Activated Carbon (GAC) removes chlorine, bad tastes, and odors. Kinetic Degradation Fluxion (KDF) media is often added to control bacteria and mold growth inside the filter when it is not in use, which is a major advantage for RVers. Finally, a Carbon Block offers a denser form of carbon filtration, leading to longer contact time and superior chemical reduction compared to loose GAC.
Flow Rate and Pressure
A high flow rate is essential to prevent a frustrating drop in water pressure when using your RV’s shower or faucets. Look for wide-body inline filters or, better yet, canister systems that explicitly state a high flow rate, such as the Clearsource Ultra (4.5 GPM). Features like flexible hose protectors and anti-kink connections also help ensure smooth water flow by preventing bottlenecks at the connection point.
Certification (NSF/ANSI)
NSF/ANSI certification is the gold standard for filtration effectiveness. Certification to NSF/ANSI 42 confirms the filter reduces aesthetic impurities (like chlorine and taste). Certification to NSF/ANSI 53 confirms it reduces health-related contaminants (like lead). Always prioritize filters that are independently certified, as this provides a third-party assurance of the product’s claims.
System Type (Inline vs. Canister)
Inline filters are simple, cheap, and disposable, offering great convenience for aesthetic improvement. Canister systems (like the Clearsource) are more expensive, bulky, and feature multi-stage filtration with separate sediment and carbon block filters. The canister system allows for sub-micron filtering and much better protection against serious contaminants like bacteria and cysts.
Advanced RV Water Purification
While inline and canister filters handle the bulk of filtration, some RVers opt for a further layer of purification. This often involves systems that target minerals or biological threats. Hard water, for example, is common in many areas and can leave unsightly spots on dishes and damage your water heater. Using a dedicated water softener, which employs ion exchange to remove hard minerals like calcium and magnesium, is the only way to solve this issue.
Conversely, if you frequently draw water from unverified sources (e.g., non-potable taps), a filter with a VirusGuard filter or a dedicated UV light system will offer the maximum protection against biological pathogens like E. coli, Giardia, and viruses. These measures are extra steps but become critical for full-time travelers or those concerned with waterborne illnesses.
How to Use Best RV Water Filters
Properly using and maintaining your water filter is key to maximizing its lifespan and effectiveness.
- Step 1: Setup/Prep
Before first use, attach a water hose to the filter and run the water through it for a few minutes (outside your RV) to flush out any loose carbon fines. Always connect the filter to the water source before your RV. Note the flow direction indicated on the filter to ensure proper installation. - Step 2: Core Usage & Best Practices
Always use a water pressure regulator before your filter and RV to prevent damage from high-pressure hookups, as filters can be sensitive to pressure spikes. If you have a multi-stage canister system, use the larger micron sediment filter first, followed by the finer carbon filter. - Step 3: Optimization/Safety/Maintenance
When storing the filter between trips, disconnect it, drain the water, and place it in a plastic bag to prevent it from drying out, which can compromise the KDF media’s ability to control bacteria growth. For longer storage, many RVers refrigerate the filter to further deter microbial growth. - Step 4: Troubleshooting & Pro Tips
If your water flow drops significantly, it’s usually a sign that your filter is clogged with sediment and needs to be replaced. For heavy sediment, consider adding a low-cost, disposable pre-filter before your main system to prolong the life of your more expensive carbon filter.
Frequently Asked Questions
What is the difference between an inline filter and a canister system?
An inline filter (like Camco) connects directly to your hose and is a single, disposable unit, great for taste and odor (aesthetic filtration). A canister system (like Clearsource) uses large, replaceable cartridges housed in durable containers, allowing for multi-stage filtration (sediment, carbon, sub-micron) for much more comprehensive protection.
How often should I replace my Best RV Water Filters?
Most disposable inline filters recommend replacement every three to six months or after 1,000 to 2,000 gallons of use. Canister filter cartridges typically last longer, often six to twelve months, but this greatly depends on the sediment level and quality of the water sources you use.
Does an RV water filter reduce water pressure?
Any filter will reduce water pressure slightly, but poorly designed filters or clogged filters will reduce it severely. Choose a wide-body filter or a high-flow canister system with a dedicated sediment pre-filter to minimize the impact. A pressure regulator should always be used to protect your RV, regardless of the filter.
What is KDF and why is it important in Best RV Water Filters?
KDF (Kinetic Degradation Fluxion) is a high-purity copper and zinc alloy used in filters. It helps to reduce chlorine and heavy metals, but its most important function for RVers is its ability to control bacteria and mold growth inside the filter when water isn’t flowing, which is common in parked RVs.
Are all Best RV Water Filters safe for drinking water?
Filters that are NSF Certified to standards 42 or 53, or explicitly stated as “food-grade” or “lead-free” are generally safe for drinking water. Inline filters primarily improve aesthetics, while multi-stage systems (especially those with 0.5-micron or lower ratings) provide a higher level of health-based filtration for contaminants like bacteria and cysts.
Final Thoughts
Selecting the Best RV Water Filters is a crucial decision that impacts your comfort, health, and the longevity of your RV’s plumbing. The most important buying considerations are choosing the right micron rating based on your contamination concerns (20-micron for taste; 0.2-micron for bacteria) and prioritizing filters with NSF certifications for verified performance. By focusing on quality filter media like GAC and KDF, and ensuring a good flow rate, you can make a thoroughly informed decision.
For most buyers, the Camco Tastepure RV Water Filter (2-Pack) offers the best balance of aesthetic performance, convenience, and value in an inline format. If you need virus and bacteria protection and frequently use questionable water sources, choose the Clearsource Ultra RV Water Filter System for its proprietary VirusGuard filter and robust, comprehensive protection.
