1 of these filters = a new machine
June 6, 2017
It seems there may be multiple suppliers for this filter. I have bought this filter 3(?) times and the first one was great. The second one seemed to acquire a burning smell after a few months, so i replaced it. The new one I received continued to emit a burning smell. It began to frighten me so bad I contacted GermGuardian and they sent me a new machine under warranty.
Since the filter was almost brand new, I kept it (at the advisement of GermGuardian support) The burning smell remained even in the new GermGuardian. The filter that came with the machine does NOT emit this smell. (I kept the old GermGuardian and the results between the two filters are consistent - no burning smell in the old machine when paired with the NEW filter)
Would give 1 star but I received a new GermGuardian as a result...I'll look for new Carbon Filters and HEPA filters going forward for BOTH my GermGuardians
