Product Description

With the power to humidify an entire 2,700-square-foot house, this model’s bulk is quite economical. Plus, a special air-flow system lets you stow it out of the way in a corner or against a wall. Using an evaporative system and unheated, natural, evaporated water, this humidifier requires less energy than warm mist or steam units. You also won’t have to deal with white dust, spray, or mist on furniture or floors. Other benefits of the evaporative system include: relief from symptoms of dry skin, itchy eyes, chapped lips, and scratchy throat; it prevents plants and furniture from becoming overly dry; reduced static electricity protects computers and electronics. In addition, this humidifier has a high-performance wick that traps mineral deposits, and a two-stage filter to reduce pollen, dust, smoke, and other odor-causing particles from the air. Two water bottles hold and disperse up to 13 gallons of water per day, for up to 24 hours, at 30 percent humidity before needing refilling. The bottles remove and refill easily and neatly in the sink via an included hose. The digital humidistat makes it easy to set preferred humidity by just pressing a few buttons. The humidistat also automatically turns itself on and off to maintain a set humidity level, displaying both current and desired humidity levels, at all times, on the LCD. In addition, this humidifier’s fan offers variable speeds, including a quieter nighttime setting. This humidifier measures 28 by 13-3/4 by 22 inches with casters attached below, allowing easy transport from room to room. Bemis covers this unit under a one-year limited warranty. --Cristina Vaamonde

Bemis Digital control humidifier

Reviewer: Stephen T. Haer,
This machine is quiet and works very well. It keeps the humidity level in my house at 55% at a fairly low fan level.
It does the Job.

I have used it all this winter and it did the trick. My wife was suffering from nose bleeds and cracked skin before we bought this and now she is fine. It holds enough water to only need changed about every other day. The lights that tell you when the resivour needs changed can be seen from across the room. I run mine at the lowest fan speed and it is like it isn't there when the TV is on. With the room quiet you know its there but it isn't annoying. I was dissapointed with the airfilter. It looks like one on a furnace and is loosley attached to the back. It's deffinitly not HEPA quality if thats what your looking for.

Tropical is not a word that comes to mind when thinking about Boston in the winter (although, with the magic of global warming, it may not be so far off...). One thing that has been very difficult for us the past few years has been the dryness of the winter months with the associated dry nose, throat and eyes. We bought a Venta Airwasher and, I must confess, this is largely a waste of money. It's well-intentioned, but just didn't really add much moisture to the air. At the same time, the Venta was very expensive to buy and expensive to operate needing lots of additive. As one reviewer put it: "Holy mother of G*d! $439 and for what?!"

That about sums up our experience with the Venta...

So, as per usual I spent days and days reading about humidifiers and learning that, basically, they all have craptacular aspects, but a few emerged as really promising. One of them was the Vornado, which a friend has and enjoys. We really liked the design and the technology of this unit, but found that for a little bit more, we could pull trigger on the Bemis 4D7 800 Digital Evaporative Humidifier w/ AirCare® Filter. The main differences we could see were that the Bemis had a bigger capacity for taking care of our whole house basically in the same way as the Vornado, and with a few added features:

* Disperse up to 13 gallons of water per day over 2700 square feet of space.
* Holds up to 5.5 gallons of water.
* Continuously variable fan speed setting with quiet night-time setting.
* Digital Control Panel
* Automatic humidistat maintains optimum humidity level.
* Removable power pack simplifies cleaning.
* Concealed control panel maintains the clean, smooth lines of the unit.

So, I hooked it up and put it in our foyer and it seems to be doing a good job. It's a nice machine, pretty clean lines and goes well with the house. It is BIG, however, and it's like having a radiator in that room now, but the space was sort of dead anyways, so it's no great loss. One key thing, however, is that, just like the Vornado, it makes the GLUG GLUG GLUG sound from time to time, which is taking some getting used to...

In my search, NO humidifier is perfect--they all have a number of flaws. This unit seems to be among the best in that it does a good job adding humidity to the air (but not over-doing it as some complain with warm-mist humidifiers) and is fairly easy to clean. In sum, this is an excellent humidifier that is well-made and does its job admirably. Recommended.

Replacing our old, non-digital Bemis model with this one

We had a Bemis humidifier (12 gal) that just died after working well enough for NINE winter seasons. As best I can tell, this Essick 4D7-800 is the same model (apparently Essick took over the Bemis products years ago), but with added digital controls. In my online research for a new "whole-house" humidifier yesterday, I found more complaints than praise for ALL brands and models. So, I just ordered this unit, with fingers crossed, in hopes I can get 9 years out of this one, too. Yes, our old unit was cheaply made and the blowing air was moderately loud on high, but it did ok for our 4300 sq. ft home. (We also have a humdifiying unit on our entire heating system, but still need a boost from that!) We ran it pretty nonstop for about 4-5 months a year, only cleaned it once after each season, and changed the wick (~$17) once a year. We refilled the large, heavy plastic bottles once a day and added a small cap of generic bacteriostat treatment to about every other bottle refill. The appearance of the unit itself is not as bad as the fake plastic wood look, and pretty unobtrusive in our foyer.

This humidifier is a beast! It's about the size of a TV set. However, it's on casters, so you can easily roll it out of the way.

When you get the fan really rolling, it moves some serious air. I'm not convinced it's evaporating as much volume of water as claimed, though, because the tanks sometimes last for days before needing a refill. Also, the "empty" indicator is very low-tech. It has already failed and we need to check the tanks periodically.

But the bottom line is, our house was unbearable dry and now it's better. I can't argue with the price of the unit or the amount of electricity it uses. Overall, I prefer this wick/fan system over our old humidifier, which took lots of juice and shut off every time the heating element needed scraping to remove crusted-on minerals.
