I also upgraded from a Whisper 60. I purchased a AC
110 on 06/15/2005. After 2 weeks of running it started making a loud noise. You could feel the vibration in the motor unit if you put your had on it. Also if you took the filter apart and just ran the motor off of the filter you could still hear it. I took the filter back to PetSmart and the guy at PetSmart said they had 2 others come back that week with the same problem. I got an exchange with no problem and this one does seem to be quieter than the other AC
. I contacted Hagen about the AC
problem and they sent me a reply that they have had very little issues with this filtration system but if I would send them the motor they would replace it.
I would recommend taken the filter back for replacement. I really like the AC
filter system but I couldnt stand the noise from it. If this one starts doing the same thing I will have to make another choice on a filter system. I guess it would be a canister type next. I'm not really into the bio-wheel thing.
