The Ultra Fine disposable filter is made specifically by Philips Respironics for the all new Dreamstation! Coming in a pack of six filters, you'll have plenty to go on for a while without having to constantly buy them. The Dreamstation filter is disposable so you just replace it when it is time to do so. Being housed in a light blue frame the filters main job is to block any dust particle from getting into the machine. For added protection this filter can be used with the reusable filter to further prolong the overall life of each disposable filter.
This six pack of disposable Respironics CPAP filters do not include the reusable filter as that is a separate purchase which can be purchased on the Reusable Filter page(add link to that filter here) It is also recommended to replace the filter after 30 days of continuous use or earlier should there be an ambient amount of greying or browning noticed on the filter during regular weekly checkups. These cannot be washed and reused therefore to ensure zero compromise in Sleep therapy please replace them as needed.
