He says that it functions beautifully and maintains comfortable humidity both upstairs and downstairs – as should be expected from the best whole house humidifier. However, he was not impressed with how loud this unit is and mentioned that there is no easy way to fill the water bottles that come with the unit.

Another user from Phoenix, Arizona was duly impressed with the humidity output for this whole house humidifier but, he suggests buying more than one unit if you live somewhere really hot like Arizona – overall, for the money he paid, he thinks it is an okay value.

Another customer really loves the way this humidifier works but really found it difficult to handle for a couple of reasons: first, the caps on the bottles are difficult to open so she advises not buying it if you have wrist or hand troubles; she also found the bottles to be quite heavy when filled to capacity. She also mentioned having difficulty finding replacement filters for this whole house humidifier.

From another user – the unit is amazing, but only with the original filter. As soon as the original filter wore out, he could not find a decent replacement anywhere and the filters he could find diminished the function of this whole house humidifier considerably.

Other customers have been thrilled with the controls on this humidifier. They love how easy they are to use and they love the auto-off feature as well.

In summary, we think it is safe to say that this whole house humidifier is an amazing unit for actual functionality – it humidifies beautifully, it is easy and convenient for most people to refill and use. People also really like the controls on this unit. Still, there are some common complaints. First, that this whole house humidifier is just noisy – most customers do not recommend using it in bedrooms. Second, there have been lots of problems with replacement filters so you might want to really shop around for a good unit with easier-to-replace filters.

  1. Essick Air Aircare EP9 800 Digital Evaporative Humidifier

essick air evaporative house humidifierThe Essick Air Aircare EP9 800 Humidifier is fairly compact, only measuring 18 x 18 x 27.25 inches. It is a little heavy at 27 pounds so it is a good thing that it does not have to be moved very often. We really like that this humidifier crosses over as a decorative piece as well as a functional one – you can display something like a plant or statue on top just like you can with any other pedestal and, it also has a nifty interchangeable tile arrangement on top so it can be matched to any decor. Another feature that we really like about this whole house humidifier is that it has a wide spout on the front for filling it with water so there is never any need to haul heavy bottles to it.

Again, it is important for maintenance and the life of the machine that you change the filters as often as necessary for your level of use. Also, using a bacteriostatic water treatment of some kind will help prevent mold, mildew, and hard water damage.

Overall, reviews for this whole house humidifier are almost entirely positive, the biggest complaints are that the humidistat and digital displays are not accurate – of course, this problem can be easily handled with external devices as many users have done – and, a very minor complaint that there is a light that is always shining on the unit. One user handled this simply by putting a bit of weather stripping over the light – it did not interfere with the functioning of the humidifier at all but did block the light so it was not disturbing.

One customer shared rave reviews about how beautifully this whole house humidifier blended in with her dark wood furniture and other décor. She was especially tickled that it could be used as a plant stand and that it didn’t stand out as an appliance in the middle of the room.

  1. Essick Air AirCare EP9 500 Digital Evaporative Humidifier

aircare ep9-500 home humidifierThe Essick Air AirCare EP9 500 is a pedestal-style whole house humidifier has the same decorative features as the EP9 800 – the interchangeable tile and the ability to double as a display pedestal – but it is ever so slightly smaller, measuring 17.60 x 17.60 x 27.50 inches. The other difference is that this model does not have an auto-off feature so it’s imperative that you keep an eye on water levels to keep your motor from burning out.

It’s easy-fill front-mounted spout make this one the best whole house humidifiers since it is a no mess, no strain sort of arrangement for filling.

What Have Actual Customers had to Say:

One customer says that she experimented for years with different whole house humidifiers before she found this one. All of the others had problems – mildew, disgusting filters, just not humidifying like they were supposed to. Now, she’s been using this little unit for two years now and could not be happier with it.

Another user says that they have been using theirs for going on three years now and the benefits to their family have been noticeable and amazing.

On the downside though, some customers have expressed the following complaints: One customer hates that you cannot go back and forth on the controls – if you want to take it down a notch or two, you have to cycle through all of the speeds until you get back to the start.

Another user hates that there is not automatic shut-off feature on this unit and, that is understandable since a motor can easily burn out if it runs dry for too long.

Another complaint is that it does not accommodate as large an area as it claims to.

All things considered, this whole house humidifier is a pretty good value. While it does not have all the bells and whistles of its newer cousin, the EP9 800, the perks it lacks (the auto off feature, etc.) are really more inconvenient than they are actually problematic.
