Two details make the Optimus even better than the Honeywell. First, the Optimus tanks are flat on top, so they rest stably in the sink as they fill. Second, there is a second handle on the bottom so it's easy to lift out of the sink and carry to the base. It's even quieter than the Honeywell which sounded like a drip coffee pot most of the time. The Optimus is also fairly quiet (NOTE: See update below).
Note: This appears to be a two-tank version of Optimus U-32010 3.0 Gallon Warm Mist Humidifier with Wicking Vapor System.
UPDATE Nov 2011: I just ordered a second one for the upstairs in our house.
UPDATE Dec 2011: After a month with the second unit in the bedroom, I feel I need to make a couple changes:
First, it's hardly silent. In a room where you are moving around, it's not noticeable. In a room where you are trying to sleep, it gurgles away all night. It's not unpleasant but if you are sensitive to sound when you sleep, it may not be a good solution.
Second, if the unit is not perfectly level only one tank will drain. The other will stay full.
One last thought.Read more ›
Also, in case you're wondering what a Wicking Vapor System is, the heating coils are wrapped in a sleeve which sticks into the water reservoir. The sleeve is heated and evaporates the water; minerals are left in the sleeve which is replaceable. You are supposed to check it every time you fill it up and you cannot run it without the sleeve.
My main problem was that I set this up and did not notice that the seal between the white and clear plastic on mine was bad. It leaked all of the water tank onto my carpet floor and it sat there until I noticed and this thing holds a lot of water.
Otherwise, it worked as expected, invisible steam, quiet operation. I can't say if mine being broken is common or not.
I should note that since the heating element sticks into the water basin, that water gets very hot. Also, the tank on the left does not have a sensor to stop operation if it is removed, so I would not recommend this for a child's room.
I have been able to partially clean the sleeve by soaking it in vinegar, but with the amount of mineral build-up that remained after cleaning, it's clear I will eventually need a new sleeve to continue using this humidifier. Based on the amount built up over two weeks, I would estimate one sleeve will last about 4-6 months.
As another reviewer has already pointed out, replacement sleeves are apparently not available. They are listed on Optimus's web site as part number U-30002. I was not able to find any retailers actually selling them online, although amazon does have a product page here: Optimus U-30002 Replacement Warm Mist Humidifier Absorption Sleeve for U32000, U-32010 ad U-32030, 3-Pack.
