A:AnswerThe AC5300B, only has 3 fan speeds and the UV light option. The AC5350W offers 5 fan speeds, UV light and Timer option. They both take the same replacement parts and cover the same area.
A:AnswerLeave it running constantly to continuously clean the air and let the ultraviolet light kill viruses. These things can stand to run for years and years. Why would you want your air only half as clean?
A:AnswerThe pre-filter can be rinsed, but not the HEPA filter itself. The ones I buy come with more pre-filters than filters, so there's really no need to rinse them out.
A:AnswerHad the same problem, eventually figured out that holding the timer button and either uv or speed button down at the same time for a few seconds got it working but not permanently fixed. Have to play around with the buttons each time.
