This is for [log in to unmask] (Barbara) - "Mom Barb & 6 pack: Hi, I did rceive your personal e-mail to me regarding air cleaners. I wish to extend my thanks to you for your kindness and caring enough to contact me, and I apologize for the lateness of my response. I have attempted to send you my reply by e-mail to above address, but, as Elvis sang in his famous song....."but my letter kept coming back", so after several unsuccessful attempts, ( and seeing it is a Ferret related issue),I am now attempting to contact you. Thanks to your kind and practicle advice, I paused and thought about the air cleaner longer than I normally would have, and because of that, I learned that it also ionizes the air (which means that it creates ozone, which in turn is harmful to a Ferret's lungs!) So, thanks to you and your timely advice, my FurKids will now be safe! Thanks again, and here's wishing you all in your household and your 6 pack, Tons of dooks, Raisins, and Good Thoughts!
