About 30 million people in the United States have sleep apnea. This type of sleep-related breathing disorder can affect the quality of sleep and can cause exhaustion during the day.

For those who suffer from this condition, one of the best options is to rely on a continuous positive airway pressure (CPAP) machine.

One of the crucial parts of a CPAP machine is the filter, and yet people do not always pay attention to the condition of their CPAP filters. Learn about how the filters help, the type of filters your machine may have, and when to change them.

What CPAP Filters Do

The job of the CPAP filter is to remove bacteria, mold, allergens, and even larger particles that may be found in your sleeping area. These can include pet dander, dust mites, and airborne tar from cigarette smoke. By keeping these contaminants out of the machine, the filters prevent them from entering your lungs.

The filter also helps pressurize the air it filters so that your airways remain open throughout the night.

The CPAP filters protect the machine itself, as well. It keeps particles out of it, helping it work more efficiently and allowing it to last longer.

Filter Types

There are two basic types of CPAP filters: disposable and non-disposable.

Most CPAP machines have at least one disposable filter, which is made from thin paper or materials similar to paper. These filters are electrostatically charged so they can attract even the smallest of particles.

At the back of the machine, there is usually a non-disposable filter. These are reusable filters many times called pollen filters because they work to block larger particles like pet dander and pollen.

CPAP machines that use both types of filters have dual filtration systems, with the disposable filter resting inside the non-disposable one.

You can also choose to add an in-line bacteria filter to your CPAP machine. These filters have an ultra-fine construction that can help block bacteria and viruses.

When to Replace or Clean the Filters

To make sure that the air quality you breathe during the night is high and safe, you need to replace or clean the CPAP filters periodically. If you have pets, have someone in your home who smokes, or have a wood-burning stove, you will need to replace the filters more regularly.

Disposable CPAP filters have to be replaced every two weeks. You cannot reuse them.

You will also need to wash the non-disposable filter every two weeks. You can do this in soapy water. Every three months, replace these filters with new ones.

You will want to change the disposable in-line bacteria filters every 30 days.
