Honeywell HEV620 Top Fill Tower vs Honeywell HE360 Fan-Powered

In short: The Honeywell HEV620 Top Fill Tower costs $100 less; the Honeywell HE360 Fan-Powered genuinely holds a larger room (4,434 sq ft against 493 sq ft); they are different mechanisms entirely — evaporative against whole-house; the Honeywell HEV620 Top Fill Tower costs about $16 less a year in wicks and watts.

Pros and cons

Honeywell HEV620 Top Fill Tower

  • The one number on the box that undersells the machine - the output supports roughly 60% more room than Honeywell claims
  • A real digital humidistat, so it stops when the room is where you asked for it
  • Top filling solves the HCM-350's most-cited annoyance
  • Tower footprint takes very little floor area for a 1.7-gallon tank
  • Wick filters at about $17 every one to three months add up faster than the sticker suggests
  • The tall narrow tank is hard to get a hand into for cleaning
  • Owners report the humidistat reading a few points off a separate hygrometer
  • Fan noise at the top setting is noticeable in a quiet bedroom

Honeywell HE360 Fan-Powered

  • Its stated coverage and its output agree to within a couple of percent - the most accurate whole-house claim here
  • Runs when the furnace does not, which is the whole reason to pay more than a bypass unit
  • $60 cheaper than the equivalent Aprilaire 700 at the same capacity
  • Specifically engineered for the modern furnaces that cycle least
  • 130W of its own blower, where a bypass unit costs about 20W of the furnace's
  • The onboard blower is audible near the furnace
  • Same install cost and same forced-air requirement as every unit in this class
  • Honeywell pads are a different part family from Aprilaire's, so a contractor may stock only one
