Pürdoux CPAP Tube Brush

Pürdoux CPAP Tube Brush — Because What Happens Inside Your Hose Matters as Much as What Happens Outside

Every night during your CPAP therapy, moisture condenses inside your hose. Your room temperature is lower than the air flowing through the circuit — a sufficient difference for moisture to accumulate on the inner walls. Without regular cleaning, this moisture becomes a breeding ground for bacteria, germs, and mold that you then breathe in all night long.

The Pürdoux cleaning brush is the simple and effective answer to this problem. Specifically designed for CPAP circuits, it thoroughly cleans the inside of your hose, where water alone cannot reach.

What Happens in Your Hose at Night

The temperature difference between the warm air blown by your CPAP machine and the ambient air in your room creates condensation on the inner walls of the hose. This residual moisture, combined with the organic micro-particles present in exhaled air, gradually forms an invisible biofilm. Without weekly cleaning, this biofilm can become a source of odors, respiratory irritations, and, in extreme cases, infections.

How to Use the Pürdoux Brush

1. Prepare a container of warm water with a few drops of Pürdoux soap (green tea & mint or citrus)
2. Hold the hose as straight as possible
3. Gently insert the brush from one end halfway into the hose, rotating it as you go
4. Repeat the operation from the other end to cover the entire length
5. Rinse thoroughly with cold water
6. Hang the hose vertically to air dry, away from direct light

Key Features

• Compatible with standard AND slim hoses — one brush for all your circuits
• Soft and flexible nylon bristles — effective without scratching the inside of the hose
• Optimal length — cleans the entire length in two passes from each end
• Lightweight (0.15 kg) and easy to store
• Compatible with all brands: ResMed, Löwenstein, Philips, Fisher & Paykel…
• Reusable — rinse and dry after each use

To Be Used in Conjunction with the HUM System

To take maintenance even further, combine the Pürdoux brush with the HUM cleaning system. This system, equipped with practical caps, allows you to fill the hose with soapy water and hang it for perfect drying — the ideal combination for an always immaculate circuit.

Recommended Maintenance Routine

• Every morning — wipe the mask with Pürdoux wipes
• Every week — wash the hose and mask with Pürdoux soap + use the brush
• Every 3 to 6 months — replace the hose and filters

⚠️ Important: this brush is not recommended for heated hoses (ClimateLineAir, ClimateLine Max, Löwenstein heated tube). For these models, use only a gentle rinse with warm water.

The Pürdoux brush is a hygiene and maintenance accessory. It complements — without replacing — the cleaning instructions in your CPAP device's manual.
