CPAP Filters

Most CPAP and BiPAP machines have two filter types. The coarse, often dark filter is the first line of defence and blocks fluff, hairs and other large particles. The often thinner, lighter coloured fine filters tackle smaller particles including dust, pollen and so on.

Fine filters should be replaced approximately every 2-4 weeks, depending on the air quality where you live. Coarse filters may be washable and should be rinsed or replaced at least every month.

CPAP Filter FAQ (click to reveal the answer)

1) How often do I need to change my CPAP filters?

Please consult the manual for your machine to find out how often you should change your CPAP filters, as this varies from machine to machine. Most will have two filters; a white filter which is optional and typically replaced once a month, and a black foam filter that is typically replaced every 3-6 months. Other CPAP machines will only use one type of filter. Your manual will have all the information you need.

2) What are the difference between the official filters and Intus Healthcare's filters?

More many machines we offer a choice between the maufacturer's own CPAP filters, and our own-brand ones also. We believe if you compare the two you will find no discernable difference in quality or performance between them, apart from the price. Our own-brand filters offer a substantial saving on the branded filters. However, if you feel more comfortable using the branded option then we have those available for you, too. Either way, keeping on top of the filter changing of your CPAP machine will ensure it continues to full to its full potential.

3) What happens if I do not change my CPAP filters?

Over time filters get clogged, reducing the about of airflow into the machines and causing it to work harder. The will after time begin to disintegrate, which can then allow dirt into the CPAP machine. If this happens, dust can accumulate on the circuitry inside which can lead to a failure. This would not be covered by warranty if it can be demonstrated that the filters were not being changed as required, so it is important to keep on top of. Similarly, the blower can become jammed due to a build up of dirt or dust - and of course you can end up breathing in dust if the filter is no longer performing, which is far from desirable.

4) Do you sell ResMed S9, S8, S7 and/or S6 filters?

Yes, we sell our own-brand filters for various ResMed CPAP machines. You will find them identical in appearance and performance to the official ResMed CPAP filters, or we will give you a full refund.
