Discount Essick Air 4D7 300 Whole-House Console-Style Evaporative

Customer Ratings:

It appears that the first guy to review this humidifier didn't bother to read the directions. He said there is no way to tell if the unit needs to be refilled. That is completely incorrect. The digital readout will indicate the level of humidity in the air but if one of the bottles is empty an "F" displays on the left or right to tell you that the bottle on that side needs to be filled. This unit definitely does the job but it is quite flimsy and it is very noisy. I find it hard to justify the $180 price based on build quality but it does do the job.

This humidifier does an amazing job. It raises the humidity in our entire home(split level)to a comfortable level where the winter skin-crawling sensation stops and the static-electricity in our hair and clothes goes away. Bemis/Essick stands behind their product better than any company I've encountered. Our motor froze-up and they replaced it at no charge even though it was out of warranty. They had no legal obligation to do so, but did it anyway because they had received a bad bunch of motors. They apparently value their customers and reputation.

We didn't buy this through Amazon, but I need to review it where I can. We have had to replace the power head three times dut to malfunctions, and the third time took about four months and only did we get it after complaining to the BBB!

Overall the unit does provide humidity and it is noisy on the high fan settings, but for this level of humididty to cover this volume what would you expect.

Problems with the third head now are that it doesn't notify when the tanks are out, so we have to just check it daily, but I'm not going to go through the H*** I just went through to get a new head.

The intake filters are a joke as they restrict the air flow so much, a lot goes around the filter as it has no positive seal to the unit (really, it just sits on the side).

Now, the stoppers on the tanks wont seal properly so unless I carry the tanks upright I'll dribble water all over the place (deal with Essick NO!). I'll just have to make sure that if we turn off the unit to pull the tanks.

I seriously wish there was a unit that oculd put out this much humidity and not have the issues...

Honest reviews on Essick Air 4D7 300 Whole-House Console-Style Evaporative

I agree with another review that said it is not worth the $180 price tag! This unit is very flimsy. And noisy? Gadz, if it's in the same room with you, and set on the lowest fan speed, the noise from it will drive you up the wall! On the higher speeds...I think standing next to a moving freight train would not be so loud. The old "water wheel" humidifiers were much quiter, and did a much better job of getting humidity into the air. The "clean air" filter on the back of the unit is USELESS! There is a large gap between the filter and the back of the unit.

Just like water, and electricity, moving air will also take THE PATH OF LEAST RESISTANCE. In this case air is sucked more easily through the GAP than through the filter, rendering the filter useless! GREAT ENGINEERING...what were they thinking! I put the filter in the unit, traced it with a Sharpie marker, removed it and added foam weather stripping to the back of the unit to close off that gap.

UPDATE 1/21/2012. I found that the micro switch for the left tank was sticking so when the left bottle was empty the indictor to fill the bottle would not come on. This switch also has to work so that if both tanks go empty the unit will not run.

I called customer servise at Essick-Air, told the woman who answered what the problem was, and asked if they could just send me the switch and I would fix it myself. The way she talked to me was VERY RUDE! She told me I would have to return the entire unit to Amazon, and have them order me a replacement. I guess it is much better to inconvenience the buyer than it would be just to send out a 50 cent switch! Essick-Air is one company that I will never purchase from again, and I would not recomend their products to anyone!!

UPDATE 1/29/2012 Overall this humidifier does NOT do the job! It is used in an area of about 900 sq.ft. and it will NOT bring the humidity up to a comfortable level. It runs constantly. This unit has been in the same spot since I received it, and today I found my carpeting soaking wet!! It emptied the water all over the floor. This thing is a total piece of JUNK! Essick Air is poor engineering, poor quality, poor customer service, and way overpriced for the junk that it is.

bought this item because of las vegas nv dry weather. the unit is supposed to humidify the whole home. with the blower on full speed to do that you would have to hide the unit in the garage and duct the air in because it is so loud. even at speed 1 (it has 9 speeds)it is louder than the floor stand fan i use to help it circulate the humidity. on occasion one refill bottle will empty and it doen't switch over to the other bottle and completely dries out the wick and the humidity drops dramatically. the caps that release the water from the bottles to the wick have a tendency to leak when you refill them so you have to be quick when putting them back into the unit or you will get water dripping on anything in their path which includes the control panel. when working properly it does a good job, but boy the manufacture does need better quality control.
