         | 
         | > ...In general, we prefer evaporative humidifiers because we
         | find them less messy and less likely to over-humidify a space;
         | however, you will need to replace the wicking filter on a semi-
         | regular basis, and the fans might not be the best option for
         | people who have pets or particularly dusty homes. The best one
         | for you will be whichever one you're actually willing to deal
         | with and maintain.

       | 
       | Last year, I noticed that ultrasonic humidifiers were now very
       | popular and cheap on Amazon, and got one. The review sites

       | 
       | I started with distilled water, and it worked great - the
       | wick/filter stayed in pristine shape for the 3 weeks I did so.
       | However, buying distilled water was about twice as expensive as
       | changing the filter every two weeks: $0.99/gal at 1-2 gal/day vs
       | a $6.99 Walmart-brand filter. I haven't looked around to see if I
       | can find cheaper reverse-osmosis water.
       | 
       | I have not had to clean the fan yet, but that does seem
       | difficult.
       | 
       | My biggest issue is the fan noise. The machine only works _well_
       | when set to the highest speed, but the fan is quite loud at that
       | setting. I have the machine a few feet away from my bed, and High
       | makes it hard to sleep. Medium /Low are no problem, so I just
       | leave it on all the time on Medium.
       | 
       | Refills are only an issue if you carry the tank by the handle. I
       | only use the handle to take it out of/put it into the unit, and
       | carry it upside-down in my arm when taking it to the bathroom to

       | * Maintenance is a new water panel yearly (about $20) and some

       | 
       | * You need smart controls or to regularly adjust a manual

         | Agreed. Recently bought a handheld vacuum cleaner. Wirecutter

         | (very cumbersome, heavy, short battery duration, not that easy

         | local store instead. The random one was $50 (instead of
         | $250-400 for the Dyson), has same or better suction, way easier
         | to use and the battery lasts about 50-100% longer per charge
         | (7-10 min instead of 4-5 min for the Dyson).
         |

       | Cool Mist humidifiers are just hard IMO.
       | 
       | 1. Warm Mist humidifiers work by boiling water. This has the
       | downside of... well... boiling hot water hanging around the area.
       | But otherwise, these are the simplest and are only ~$20 or $30.
       | 
       | 2. Cool Mist humidifiers try to get around the boiling water
       | issue. Since they humidify at room-temperatures, they're a lot
       | more efficient... but now bacteria / mold is growing constantly.
       | You can somewhat fix that with chemicals / filters / whatever,
       | but now those filters need to be cleaned, or those chemicals need
       | to be replaced on the regular.
       | 
       | In both circumstances: minerals in the water will harden into
       | 'slag'. More so in warm-mist humidifiers actually (because
       | boiling water separates water from minerals very naturally).
       | Cool-mist humidifiers often carry the slag into the air, forming
       | "white dust" all over your furniture.
       | 
       | The slag dissolves with vinegar in ~20 minutes or so (unless its
       | been building up for a while). But its never an easy job to
       | clean.
       | 
       | I prefer my warm-mist humidifier. Centralize the slag into one
       | spot and clean it with vinegar every few weeks. Better than
       | dusting off all my furniture in the room.

       | As someone living on the east coast and having a very sensitive
       | nose, I have tried different humidifiers and sadly no humidifiers
       | have been perfect. There are three main types of humidifiers:
       | 
       | 1. Warm mist humidifiers boil water and generate steam which
       | humidifies the air. But, they are a burn hazard and consume a lot
       | of energy.
       | 
       | 2. Cool mist (non ultrasonic) work like miniature swamp coolers.
       | They are essentially fans which draw air through a wet paper
       | wick. The Honeywell mentioned in the article is of this type. The
       | fan is however very underpowered and it doesn't work well in
       | anything bigger than a small bedroom. Vornado makes a version
       | with a much more powerful fan which works very well in large
       | rooms, but their tanks are finicky and prone to breaking and
       | leaking. The wick absorbs minerals in the water and will
       | eventually have to be replaced.
       | 
       | 3. Ultrasonic humidifiers: A vibrating diaphragm will aerosolize
       | water. Unless you use distilled water, minerals in the water will
       | turn into dust and reduce air quality.
       | 
       | I happen to like the non ultrasonic cool mist ones because they
       | use less energy than the warm mist ones and replacing crusty
       | wicks is cheaper than using distilled water in ultrasonic ones.
       | The problem is everything currently on the market has issues. Any
       | company making incremental improvements to existing cool mist
       | humidifiers will probably get a lot of eager buyers.

       | I got one because in Arizona, the water quality's terrible, but
       | the air is _bone-dry_ to the point it turns your skin to
       | sandpaper. The hard water means that vaporizing humidifiers fill
       | the air with white dust that coats _everything_ , because they
       | vaporize the minerals. Evaporative humidifiers don't; the
       | minerals all end up in the filter. And, while an evaporative
       | humidifier has no trouble going through a full tank of water
       | overnight on the lowest settings in AZ, it phsyically can't
       | oversaturate the air like a sauna in the way that a vaporizing
       | humidifier does.
       | 
       | The air in the north east just doesn't get dry enough (maybe in
       | winter, but then you don't have the AC fighting your humidifier),
       | and if boiling a pot of water is what the author's looking for,
       | an evaporative humidifier just doesn't do that.
