At what cost

Honeywell Evaporative Cool Moisture Humidifier comes with 3 color options (Black, White, White and clear) and is priced differently. Expect to pay 73 to a high 106 dollars for a brand new model. No matter which color version you choose, you will get the same water tank size, same humidity adjustment, same warranty period, and same moisture output. The high wick filter replacement cost is something you need to be aware of. On monthly replacement, the filter's cost will easily match a brand new model. Not a cheap model to maintain.
Where can you buy a Honeywell HEV685W or HEV685B Humidifier? Amazon of course. It has the most color options, the best price, free shipping, and the best bundled deal. Honeywell website is also a good place to go with guarantee stock availability and competitive pricing. Both Amazon and Honeywell site has plenty of wicking filters stocked up but pricing vary depending on the package. You can try other online retailers like Walmart, Best Buy, Home Depot but options are very limited.

Other variants

Bigger, better, and bulky as you can tell with the caster wheels inclusion. Slightly more expensive with fewer color options.

Smaller, lighter but with a bigger 4-gallon water capacity. If you don't need the best humidifying coverage, this model will do just fine.


  • Wide large room coverage with 24 hours of continuous operation (low setting).
  • Adjustable humidistat automatically turns on and off to maintain set humidity levels
  • Easy to refill and emptying dual break-resistant water tank with carrying handle.
  • Easy to clean design with a large surface and wide tank opening.
  • Antimicrobial protect pre-filter that removes white dust and inhibits 99.99% of mold and bacteria growth.
  • 3-year manufacturer warranty.


  • Not the"prettiest" humidifier in the market with its large air vents the old-fashion dial knob controls.
  • No digital display, no precise humidity adjustment.
  • Replacing the protec wicking filter can be very costly if you intend to replace it monthly.
