    Comments about 3-Speed Digital Ambient Air Cleaner:

    Have had this machine for a few weeks now. The initial unit shipped was damaged (poor packaging) and didn't work at all. Tyler replaced it immediately. The second unit worked fine for about an hour after which the "change filter" light began flashing and could not be reset according to the instructions. The manual was no help at all and only referred me to the Delta customer service 800 number. I did call them and was basically told they had no answer. I continue to use it with the flashing red light but obviously will not be able to tell the condition of the filters without getting on a ladder and inspecting them.

    The unit is very loud but as far as I can tell works fine.

    I think the unit is OK but there are probably better products on the market. I have always been well pleased with Porter/Cable and Delta tools but must admit to being a little disappointed in both the unit and the customer service from Delta.
