BE WARNED

I purchased this to replace the filter on my 04163 unit and although the description (and box) say it is compatible with this unit, it was the wrong size! I still don't know how to order the correct one.

Great pre-filters

These filters are great and are very easy to install. I live in a house that gets dusty quick even without my 2 Australian Shepherds. I even vacuum off (don't know whether Hamiltom Beach would approve though) the pre-filters every week or so. The unit definitely catches a lot of the dog hair that floats through the air after I brush the dogs. I've found that the pre-filter does a pretty good job of catching hair and dust before it even gets to the HEPA filter.

filters

We received the filters in two shipments, which was perfectly fine, as we only needed one box at first. We ordered a double shipment to save on shipping and it is nice to have them on hand when we need them next. These filters are difficult to locate in nearby stores, so this is easy to order through Amazon!
