The GoodKnight 420/ 425 Pollen Foam Filters are used with the GoodKnight models that were manufactured by Puritan Bennett.
The filters can be used with the following models:
GoodKnight 420G
GoodKnight 420S
GoodKnight 420SP
GoodKnight 420E
GoodKnight 425
The filters are recommended to be replaced every 3 months, but to be cleaned every month! When using with a ultra fine filter, place the ultra fine filter in first and then the foam filter.
I was happy to be able to buy just the cushion for the mask, although I did feel it was very expensive at $75. It seems to have increased to more than double in the past year. However, it was shipped promptly and received within three days and there were no shipping charges. I hope we will continue to be able to buy parts for the mask and hope they will not increase anymore in price. It is cheaper to buy a complete mask, but if you have a few masks on hand that only need one or two parts it does not make sense to throw them out.

Appreciation
Reflecting on my angst of purchasing products from a non Canadian company I decided to Google CPAP products. To my delight I located CPAPClinic.ca I telephoned and chatted with a young lady, Julie Benson. Directions were provided from my abode in Mount Forest Ontario and I arranged a rendezvous on a Saturday. The warm and professional greeting was obviously a sign the young ladies enjoy what they are doing. After a few moments with Ms. Benson, my queries centered on some technical data and she invited Ms. Santos to provide the information. I was quite impressed with Ms. Santos professionalism, knowledge and recommendations. I did not feel pressured or rushed. I have the items I ordered and will place all future orders through this company. Both of these ladies are excellent ambassadors for CPAP Clinic and they are jewels as front line personnel for this organization. Robert Plamondon Mount Forest Ontario
