Why you should not inflate an air mattress with your mouth

In short: do not inflate an air mattress with your mouth, because moisture from your breath stays inside and causes mould and bacteria. This damage is permanent and usually not covered by warranty. Always use a pump or an inflation bag.

Inflating by mouth may seem like a convenient and quick solution, but in the long run it costs hikers dearly. Here are the reasons.

Why is your breath bad for a mattress?

Human breath carries a lot of moisture. When you inflate a mattress by mouth, the moisture collects inside, where it cannot easily escape. This creates an ideal environment for mould and bacteria. Over time it can cause:

• an unpleasant smell
• health problems, especially for allergy sufferers
• mould spreading inside the mattress

Can the damage be repaired?

Because of moisture and mould, the inner material of the mattress can begin to break down or turn sticky, especially in air mattresses. This kind of damage is permanent and is usually not covered by warranty. The mattress rarely returns to its original condition.

How to inflate a mattress the right way

• Use the pump that comes with the product, such as a hand pump, foot pump or electric pump.
• Many quality sleeping pads come with a mini pump or an inflation bag that lets you fill the mattress hygienically and safely.
• If you use a separate pump, make sure it is clean and does not contain moisture either.
• If you have inflated the mattress by mouth anyway, store it with the valve open after use. This lets moisture escape and the mattress dry.

How to look after your mattress so it lasts

Good gear lasts a long time when used correctly. Besides using a pump, keep the mattress dry and the valve open when stored after a trip. If you would rather try gear before buying, see our hiking gear rental.
