Your Post began with:
"I want something that I can use tap water in, hence, the non-ultrasonic".
It is simple common sense...
we have minerals in our tap water. If you have a method of dispersing the water
into the air, either the minerals go with it or stay behind.
If your humidifier turns the water to steam using heat, the minerals are trapped behind,
as the temperature it runs at does not disperse the minerals into the air. You then have to "clean" the mineral build-up from the humidifier. It is messy and takes some work.
If your humidifier turns the water into "artificial steam" like the Ultra-Sonics do,
vibrating the water into fine particles and dispersing them with an internal fan into the air,
then the minerals go with the water, and create that fine dust! Again, messy!
Or, if using a spray system, this too will not separate the minerals, but carry them into and
onto your plants. Again, creates some work. You either have to clean your plants,
OR
"clean" the water before it gets to your humidification system !
Really, the choice is yours. Some plants tolerate some minerals better than others,
and you can sometimes flush the pots and plants off with fresh water. When the plant absorbs moisture, it may take some minerals too, but any not absorbed, or any water that has a chance to evaporate at the surface of the potting medium, will leave and build
mineral deposits. This can be seen as a crusty looking crud on the surface of potting media.
I think everyone will be able to recommend a humidifier that they like (or one they don't),
but you will have to decide how you will want your "system" to handle dealing with the minerals.
I myself use both "systems" and it is a hassle lugging rain water, but it is free and it works good! I put in rain barrels years ago, and they work nice. Distilled water gets expensive and a Reverse-Osmosis costs a bit in start up for a system.
Oh, the things we do to provide "Shang-ra-La" for our plants!
But as you know, it is worth it, and besides,
their lives depend on it!
