First up is a Whisper Second Nature filter. It takes large whisper cartridges. I am unsure of the size of the filter. I can send pictures upon request via e-mail.
Second up for Trade is a Biowheel 150. All parts are included.
I am going to throw in the filter cartridges for each of them. I won't use them and they don't need to go to waste.
Make me an offer
