Air Innovations MH419 vs LEVOIT LV600HH

Don't plan on filling this humidifier at the faucet. If you take the water tank off, you can't flip it over in order to prevent drips as you carry it..

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 mist outlet points towards the front and cannot be aimed in any other direction. I like the large capacity of this humidifier. I only have to fill it once every 24 hours when I put it on high. It’s not quite the most powerful humidifier that I own—I have another one that puts 1 gallon of water into the air in just 12 hours

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

I've got a smaller cool mist humidifier that never caused either of these problems. I got this because it's top fill and holds more water. One gallon vs half a gallon. So unless you've got soft water or want to pay for distilled water, don't buy this

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
