FREE: Philips air filter

The listing, Philips air filter has ended.

I didn't even know these existed until I was helping my friend clean out a house they moved into. They didn't want it and it's brand new so I post for you all!
This is a Philips HR 4977 replacement filter. This is for a Philips clean air system model HR 4381 and HR 4383 (that is the info on the outside of the box)
(Inside the box the filter says) Norelco clean air filter model: CAF 5,9 or 53
The box also has a paper that tells how to purchase future replacement filters.
I believe this is a HEPA filter and that is all I know about it I hope the pictures tell you anything else you need to know, but if not I can try to help.
Free shipping and I only ship to Listia verified addresses
Happy bidding
