These air filters are an alternative to the ResMed S6 web backing foam set filters 21944, 21935 and 21936. These filters are made by Tiara Medical Systems so they are not the original ResMed filters. They will fit your S6 series CPAP just fine and are of similar quality.

These ResMed S6 alternative filters are suitable for:

• ResMed S6 Lightweight
• ResMed S6 Plus
• ResMEd S6 Elite

Why Buy These Filters?

Our alternative filters are often cheaper than the branded originals even though they are of a similar high quality. Unlike the CPAP machine, there is nothing high-tech about foam and paper filters so there is nothing to worry about in terms of the quality of the air you will be breathing in. Also, if you are placing an order for another item here anyway, you might as well get some filters at the same time, avoiding packaging and postage costs.

Filter Replacement

Check your CPAP's manual for exact instructions on how to replace the old and dirty filters with your new ones. It is recommended you check the filters regularly as dirt may build up. Some organisms feed on what filters catch so it's important to keep an eye on the filter quality to avoid allergic reactions and respiratory difficulties. Depending on what sort of area you live in, you may have to change filters every month.
