LEVOIT LV600HH vs Venta LW25 Airwasher

As an experiment we used it for a tank full in another room all day with little interference from currents or people walking by with the warm mist. It was much more effective and consistent in this decent sized room and agreed with the hygrometer 90% of the time. However, when I walked by, opened the garage entry door (12 feet away) or did activity behind the unit (reading newspaper, sitting up and down, etc), it did the same inaccurate and fluctuating humidity detection causing the unit to not achieve the desired level. And as mentioned the unit can 360 direct mist, but the left front is where the humidistat is and that's not a good place to direct it

Why do I say this? Because I don't see the humidity levels drop or spike when I'm not using or using the unit. I have a pretty fast reacting hygrometer which detects the changes in 30 minutes max. Does it clean air? For sure it does, simply because the water in the tub gets dirty. But how big of a radius does it really affect? I'm not sure, I have no proof either way

We spent a week coming up with products on amazon, but we never settled on any. On a whim, I purchased this one and got it next day (I'm a Prime member). I had stocked up on distilled water for this little guy prior to it arriving, so we could get it set up and running as soon as it came in. Opening the package I was impressed, the product was very well packaged and came with a buttload of instructions and filters for essential oils (which we wont use)

The area this is trying to service is about 800 sq feet, mostly open concept floor plan. At the highest setting on the coldest days when the heat is cranking this will hold that space at 27% - 32%. On milder days when the heat comes on and off throughout the day I can hold 35% at the middle fan setting. From a noise perspective, it is no louder than an average small fan

The tank is pretty large and holds a good amount of water. Nitpick on the tank: even when it’s closed/sealed well and you pick it up, water tends to splash into the basin and sometimes surrounding the device. Made me nervous to place directly on my wood furniture (it’s on top of a waterproof mat now). All in all, I’m happy with my purchase, just wish the humidity reading was consistently accurate

The advantage is that it doesn't consume wicks. Given the additional cost of the unit, you probably have to run it for about 5 years to make the difference up. It does have a fairly large water capacity for its size, since the 'tank' is integral to the unit, and it's low power (although no better than a wick type). It is also fairly easy to clean, although the plastic disks can't really be serviced since the disk unit can't be disassembled
