Staying Safe from NTM: A Guide for People with Chronic Lung Conditions

People with lung conditions like Chronic Pulmonary Aspergillosis (CPA), ABPA, bronchiectasis, or anyone with a weakened immune system, can be more vulnerable to nontuberculous mycobacteria (NTM) infections. NTM are environmental bacteria commonly found in soil and water systems — including those in our homes, travel vehicles, and public places.

This guide explains where NTM are found, how to reduce your exposure, and what simple steps you can take to protect yourself.

🏡 At Home

Where NTM Can Grow:

• Showerheads and taps
• Bathroom and kitchen plumbing
• Water tanks (especially warm or old systems)
• Humidifiers, CPAP machines
• Garden hoses and outdoor taps
• Dishwashers and boiling water taps

How to Reduce Risk:

• Let hot water run for 30 seconds before using showers or taps
• Clean or replace showerheads every 3–6 months
• Soak removable parts in 5% white vinegar regularly to reduce biofilm
• Set your hot water temperature to 60°C or above if safe
• Avoid inhaling steam directly from showers, kettles, or boiling taps
• Only use boiled or filtered water in humidifiers or CPAPs
• Don’t drink water from hoses or little-used outlets

🚗 While Travelling: Campervans, Motorhomes & Campsites

Why It’s a Risk:

Water tanks and pipework in motorhomes are often warm and infrequently flushed — ideal conditions for NTM. Shower blocks at campsites can have older plumbing and biofilm build-up.

Tips for Safer Travel:

• Drain and clean tanks regularly with specialist tank cleaner or white vinegar
• Don’t drink or cook with tank water unless boiled
• Flush taps and showers before each use
• Clean showerheads, hoses, and filters often
• Avoid breathing in steam from campervan plumbing
• Let campsite showers run for 30 seconds before using
• Consider using your own portable water supply if immunosuppressed

🏦 Public and Community Places

🧰 What About Vinegar?

5% white vinegar (acetic acid) is helpful for disrupting biofilms and reducing NTM contamination in pipes, tanks, and showerheads.

How to Use Safely:

• Soak parts like showerheads for 30–60 minutes, then rinse
• Never mix vinegar with bleach
• Use to flush campervan water systems

Vinegar is not a steriliser, but it may help reduce exposure by breaking down NTM habitats.

🙏 Final Advice

If you’re living with CPA, ABPA or bronchiectasis, small steps can go a long way in reducing your exposure to NTM. Discuss your personal risk with your medical team, and let them know if you have concerns while at home, travelling, or in shared spaces.
