We tend to trust that tap water is safe if it appears clear and odor-free. But the risk of brain-eating amoebas is cause for significant caution. For one woman, that assumption had tragic consequences.
A recent CDC report highlights a case of a brain-eating amoeba in Texas, where a woman contracted a rare and deadly brain infection caused by the Naegleria fowleri amoeba. She suffered from a fever, headache, and altered mental state before dying.
Typically found in warm rivers, freshwater lakes, and ponds, the amoeba enters the body through the nose and travels to the brain. This woman had not been swimming in any fresh water. However, she had been using tap water from her RV’s faucet for nasal irrigation.
The Risk Behind the Rinse
The CDC warns that using untreated tap water for nasal rinsing can be dangerous. Unless water has been distilled, sterilized, or boiled, tap water can harbor microorganisms. These tiny terrors can pose serious health risks when introduced directly into the sinus cavities.
While drinking this water might not make you sick, inhaling it through your nose can expose you to harmful pathogens. Never use untreated tap water for sinus rinses, in neti pots, or for cleaning contact lenses. Always use distilled, sterile, boiled (and cooled), or properly filtered water to keep yourself safe.
Filtration Isn’t Just for Drinking
This incident shows us that water that is "clean enough to drink" may not be safe for other uses. This is why comprehensive water filtration matters. And especially so for people who live or travel in RVs, use well water, or need tap water for more than just drinking.
Whether you’re at home or on the road, installing a water filtration system can provide significant protection. This system filters water down to a microscopic level, ensuring cleaner, safer water for all your needs.
Aquasure Solutions
When it comes to protecting your water from harmful contaminants, having a reliable filtration system is essential. Aquasure’s advanced filtration solutions combine cutting-edge technology with user-friendly design to deliver clean, safe water wherever you need it most. Below, we highlight two top options designed for both travel and home use.
Dash Series Countertop Water Filter Advanced Ultrafiltration
The Dash Series Countertop Water Filter is a powerful, compact solution for life on the road. The 5-micron carbon filter reduces chlorine, sediment, and bad taste. But it's the ultrafiltration (UF) membrane that adds microbial defense.
With a filtration rating as fine as 0.01 microns, the UF stage can remove dangerous microorganisms, including protozoa like Naegleria fowleri. For travelers who use tap water for more than just drinking, like nasal rinsing or hygiene, the Dash provides serious peace of mind.
Premier Reverse Osmosis System
At home, the Aquasure Premier Advanced Series Reverse Osmosis System offers one of the most advanced forms of water purification available. With a membrane that filters down to 0.0001 microns, it removes up to 99% of contaminants, including microscopic pathogens.
This system is also useful on the road for larger RVs that have the space for it. The Premier RO system helps ensure the water at your tap is not just clean, but safely filtered for all uses, including sinus rinses.

How to Avoid Exposure to Brain-Eating Amoebas
Cases of Naegleria fowleri infections, though rare, are almost always fatal.
To Minimize Risk:
- Always use treated water for nasal rinsing, neti pots, or sinus irrigation. This includes water that has been distilled, sterilized, or boiled for at least 3-5 minutes.
- Clean and dry your nasal rinsing devices thoroughly after every use to prevent microbial growth. Practicing proper technique is as essential as the water you use.
- Avoid getting water up your nose when swimming in warm freshwater lakes, hot springs, or untreated water sources.
- Wear a nose clip or goggles with a nose cover if you plan to swim in freshwater.
- Consider installing a filtration system capable of removing microorganisms at 1 micron or smaller, for extra peace of mind, especially if you use tap water for nasal or sinus applications. This aligns with the CDC recommendation.
By taking these precautions, you significantly reduce your risk of exposure to harmful pathogens like Naegleria fowleri.
Protect What Matters Most
Clean-looking water can still carry hidden dangers. The case in Texas is a heartbreaking example of how something as routine as a sinus rinse can turn deadly without the right precautions.
Whether you’re filling a neti pot, brushing your teeth in an RV, or just trying to stay safe on the road, proper filtration matters.
Aquasure systems, like the Dash and the Premier Series RO system, offer reliable, multi-stage protection designed to help you go beyond just clean enough to drink.
