Pros and cons

Pros

Built-in pump at a sub-$800 price
Marketed as '120 pint' but labelled 55 pints AHAM on the listing
6-year limited warranty per AlorAir

Cons

Same 55-pint AHAM capacity as the cheaper HD55S
MERV-1 filter per AlorAir
Warranty term differs between AlorAir (6 yr) and Sylvane (5 yr)

Our take

The HDi65S is the least expensive way in this group to get a built-in pump with a 6-year warranty. It has the same 55-pint / 1,300 sq ft rating as the HD55S, so buy it for the pump, not for extra capacity.
