Space Saver Large Evaporative Whole House Commercial 6 Gallon Humidifier for Large Rooms 2,700 sq ft. With Digital Controls, Auto Humidistat and Automatic Shut Off

This is a really great unit. works incredibly well and is easy to fill, you don't have to take the top off, just the grille at the front of the unit. It does a great job of monitoring the humidity and it’s easy to set up the fan speed and desired humidity level. Fan speed 1 is quiet, 2 and 3 quite noisy, but you don't need the higher speeds except perhaps when you first set it up as it reaches the desired humidity from very dry air in only a few hours. Our air was at 19% humidity and reached the 45% we set it up for in 3-4 hours…..that was running it at the #2 fan speed, #3 was too noisy for us to tolerate for long. Since then it has maintained the humidity perfectly on fan speed #1. It doesn’t have a big footprint. I am using filtered tap water in it. This is a great unit and I really recommend it. VERY happy with this purchase.

Although I'm satisfied with this unit, it is made with the thinnest possible plastic and feels pretty cheap. It has 3 fan settings, the second of which operates at a frequency that makes the unit shake rattle and is, IMO, completely unusable. That's OK because we use it on the highest setting in a larger house with two HVAC units. We have it in an open staircase area so it circulates and supplements an HVAC mister set up in one unit. It has been unusually cold lately and in our setup, at high speed, this unit can only get its immediate area up to 30%. When it was a little warmer, we could hit 40%. Unfortunately, this makes so much noise on the high setting, that my wife turns it down at night, and it cannot keep up. This unit puts out a lot of water, so it's doing its job, and in fact as it runs all day it has to be refilled before the day is over in our setting. While relatively easy to fill, you have to turn the fan down to the lowest setting or completely off because it will blow water back in your face at the high setting. LOL. The fill opening is behind the grate where air blows out, and is shallow enough that using a bucket to fill means water splashes against the filter and the max fill line. I would rather pour water directly into the basin with a larger opening. We have also slipped and dumped water on the floor, so while acceptable, the fill could be a little better IMO. To sum up, in our setting which is asking it to humidify too large an area, it nevertheless puts out a lot of water per day, but requires the highest setting, which we consider very noisy. The lowest setting is whisper quiet but does not put out enough water for our use. Still, it's easy enough to use, and a pretty good value, hence the rating despite some criticisms.

Wonderful product. Not perfect. Pros: - The reservoir is a good size. - The casters help... they don't move great on carpet, but with the reservoir size, it'd be hard to move it into place without the casters. - It is simple... I've had other humidifiers that were more aesthetically pleasing but which ended up drenching my floors due to over complicated designs. - It puts a good amount of water into the air. Naturally that's going to be based on your space, the airflow, the relative humidity its working against, etc. But for an evaporative humidifier, it does a good job. The cons: - Any setting except for the lowest one is loud. You can talk over the middle setting. The highest setting isn't conducive to conversation. - There are little plastic ridges on the inside of the reservoir that align the wick to form two compartments... There is the large air inflow compartment, then the smaller air outflow compartment. The wick sits in between these two compartments so that the maximum amount of air passes through it... thus increasing the efficiency of the humidifier. But the little plastic ridges that hold the wick in place are unnecessarily small. and as a result, on the highest setting, the air pressure can easily push them out of place. That lets a lot of air escape without passing through the wick. I'm providing some images to show the intended position and the position it can end up in when on the highest setting to demonstrate the air leakage. All in all, I think its a good product. I intend to get a couple bull clips to clip to the top of the wick housing, which should keep it in place.

The humidity in my condo (~1100 sq-ft) goes down to about 12% in the winter, so I need a whole-home humidifier. I used the Aircare D46 last year and it was just OK. Not powerful enough for my whole house, but it got things up in the 30% range which at least wasn't awful. Filling up the containers was annoying though, so I decided to get a larger and more powerful unit that I could fill easily. I ended up settling on this one. I've used it for about 2 weeks, so I now have a good idea of how well it works. First off, filling this thing is so much easier than my last unit. I just take a pitcher filled with tap water, and dump it in. It's that easy and makes me wish I had bought a "top-fill" unit ages ago. As for the speed settings, low (1) is pretty quiet and seems to be able to keep my humidity level at around 37% which is good for my place. I fill the water daily, but I believe it would last about 2 days before going empty on this setting. The 2nd setting is a little useless as it's quite loud, so you may as well use the the setting (3) which is a little louder, but barely and works better. I personally set the humidity to 45%, and it's able to keep up as long as I keep it filled with water. I'd say the full tank lasts about 24hrs on this setting. It does turn off once it hits 45%, but it doesn't turn off very often, so I think 45% is somewhat maxing out it's capabilities for my home. If I set it to 50% it would likely always stay on, and maybe go up to 47%-ish. Anyways, I have it on (3) when I'm not in the same room, and (1) when I am. My humidity level is always between a healthy 35-45% as a result, which I am happy with. Overall my only complain is that it's white and doesn't fit my decor at all. I can live with that as long as it keep working though.

Cet appareil est très efficace et fait exactement le travail qu'il doit faire. Simple d'utilisation. Il a un grand réservoir avec un filtre, une hélice avec un petit moteur et un contrôle électronique. Quoi de plus simple? Décembre 2018 Le 1er appareil a refusé de fonctionner quand je l'ai remis en marche l'automne suivant, 1 mois après la fin de la garantie. C'est le module électronique qui est défectueux et il ne se vend pas séparément. J'ai quand même acheté un 2e appareil parce qu'il a un grand réservoir de trois jours. J'espère qu'il durera plus d'une saison.

Works as advertised. Raised the humidity 10% in two days in my old 1800 sq ft home. Its all plastic so a bit flimsy for the money. It could use a handle for moving it across rugs as it is hard to maneuver between rooms. ( fill it in kitchen ,run it in living room). Has a unnecessary overfill hole that slops water when you fill it to the full mark and try to move it.The fan on 1 or 2 is not to noisy but 3 is to loud to be in the same room for long. The 6 gallon fill is great as with the fan on high I still get a day between fills. Over all if you have rugs it can be a little awkward to move but I would buy it again. Setup is a breeze and I am quite happy with the overall operation of the unit. I'D say a good bang for your buck.

it worked great for about 2 months and now it does not work anymore.

Works great as described ! During the winter when it was really dry like 15% humidity I needed to fill it up everyday, otherwise it can last up to a week. Quiet, multiple settings, easy to fill with a pail in one shot.
