Great for plants

So happy that I got this! My plants have never thrived so much because it will automatically change based on the needs of the time of day. I love it! And, I can control it while I’m away from home just in case I need to adjust the settings.
I would recommend this to a friend!

Price>value.

I don’t think the value for the money is worth it. It seems to work but at the same time you would expect something this expensive to blow you away, this does not. If you put the fan on high it will burn through the water tank extremely quick.
No, I would not recommend this to a friend.

I May Have Gotten Lucky?

Although there are mixed reviews on this. I have discovered how to use it best. Set your humidity level (not on auto). And set your fan speed on auto. You may set your oscillation or not. Eventually that will bring your humidity level up to what you set. If you set your oscillation on, it will stop oscillating once the humidity level has been reached. Oscillation will resume when humidity attempts to reestablish your humidity setting. Realize that humidity in your room is not uniform (opening and closing of door of windows and moving about in your room affects uniformity. So your humidifier has to play catch-up. Don't expect your oval loop to rotate for oscillation. Only the upright column on each side of the oval loop oscillates! I'm Loving this machine once I figured out the unexplained nuances of operating it. I use "Zero Water" in mine. Hopefully that will reduce any required maintenance.
I would recommend this to a friend!

Not great.

Verified Purchase:Yes
We own four Dyson cordless vacs and I am considering a robo mop/sweep.
The PH4 looks like a sculpture that needs to be on a base.
Adding water to the device is inconvenient and frankly, a pita.
I would not purchase this again when for nearly the same money I could purchase ten HEPA air filtration units.

Product seems to be working OK. However, every time I replace the water tank, it takes 2 or 3 times of positioning it before the needs water error message is cleared.
