Holmes H620 Microban Filter

I love my humidifier but I do go through these filters (about two or three each winter). I'm thankful to find them on Amazon cheaper...I was spending much more until I found them here. They do last a while longer if you take them out every week or two and rinse them with water/vinegar.

This product works really well for my sunbeam humidifier. I have had rotten luck trying to find filters where I live. NOBODY carried these! Finally, I ran across these on Amazon and lucked out with free delivery, so I purchased them just in time for winter. They do the job and arrived in a timely fashion as promised. Love it!

The filter arrived in good time. It first appeared too large for the unit, but it squeezed in OK and is working fine.

These fit my humidifier.

Develops a brown color around the edges after a few weeks of use. I guess it's normal???

Haier HDN655E 65-Pint Capacity Electronic Control Dehumidifier

This was a great dehumidifier while it worked. A plumbing leak resulted in water in my normally dry basement so I bought the Haier HDN655E dehumidifier to dry things out after the leak was fixed. It pulled the humidity in my basement down to 45% in a couple of days. After that I ran it on Sundays when I was in the basement working on my hobbies. Unfortunately it died completely after a few weekends of use. Looking around on the internet it appears this unit may have a propensity for blowing an internal fuse when power is cycled and the compressor and blower come on simultaneously.

---

I really liked the electronic controls, the humidity setting and the timed off setting. The humidity readout is in increments of 5%, and tracked very close to a fairly expensive gauge I had nearby on the wall. The negatives: 1) The blower runs continuously when the desired humidity level is obtained, only the compressor stops, 2) Momentary power outages reset the humidity control to a default of 60% (and then the unit runs and runs any you wonder why it can't pull the humidity below 60%).

---

I called Haier support since the unit was still under warranty, but the person who answered the phone was extremely curt and the repair process consisted of sending pieces of the unit back to service center in return for a new unit. It was easier just to return the whole unit to where I bought it.

This dehumidifier does exactly what it is supposed to do, removes H2O from the room. Great in our basement, no more "damp" feeling carpet and no worries the kids are playing in an unsafe enviroment. It is not "whisper quiet" as the Solarus promises, but I like the fact that it has an air output vent on the top that discharges de-humidified, dry, fresh air. Probably why it is a little louder than my old Kenmore dehumidifier. I like the air flow into the room. It is not too loud either. We use it in the laundry room with no door and you can still hear the tv on a low setting. Wouldn't want to sleep in the same room, though.

I have used other brands, namely, Sears (? manufacturer), LG, Goldstar and Whirlpool. HAIER seems to be the best.

You can get it in Wal Mart for about $179. I have bought 2 in the past 2 years, for a large basement in a house in a wooded area. Wal Mart is, however, poor in maintaining an inventory of slow moving items, and it may not be available in all stores at all times.

I purchased the Haier Dehumidifier model HDN655E a year ago.

I started to have problems with the switch that resets the unit after the water tank has been emptied and replaced,

I recently set up a system so I did not have to carry the water upstairs to empty. When I attached the drain hose, per the instuctions, I found that the water did not drain out the hose, it continued to fill the built in water tank. I still have to empty the tank and fight the reset switch.

This was my first unit. I have looked at other dehumidifiers and find others offer better systems to drain the water, the water tanks do not have to be emptied manually.

I would not recommend this unit. The reset switch is getting harder to manually reset, (replacing the water tank won't reset it,) and I don't expect it to work much longer.

The good:

---It does a great job quickly. It is a workhorse.

---I like that you can set the relative humidity setting all the way down to 30 if you want. Other units I have only go down to 50 or constant mode.

---I like that it has a timer for auto shutoff.

---The handle on the bucket makes emptying the water more convenient

--Nice, thin profile.

The bad:

---There are no scheduling for turning on or scheduled change in rel humidity types of options. But, I haven't seen this on any of these types of units. It would be nice to have.

---It pulls air in front and discharges in back. So you can't set it in a corner of the room. Other units have a side air discharge. This is important to think about before buying. Where do you plan on placing it when operating? Tucked away against the wall in the corner of a room? Can't do it.

--Dehumidifiers generate a little heat that they discharge. This comes from the dehumidifying itself.

The ugly

--It is a little noisy. I used to think that I didn't care about this feature. But, it will draw attention if guests are over. Other units I have are much quieter. But, it sounds like a floor fan on high speed, nothing more. So, if you don't care about a high speed fan sound in the room when operating, then this shouldn't matter. But, if you don't want the sound of a floor fan on high speed, then this unit is probably not for you.

I set it up in main room of our house and turn on at night with the 8 hour timer. Works out great. I use quieter units during the day.

I live in humid Florida and have allergies. Dehumidifiers often help with allergies and really do make the house more comfortable. Mold grows above 50% rel humidity. It doesn't below 50% generally. My family used to cough a lot in our house at night before we got dehumidifiers. As soon as I put one in each bedroom, the coughing stopped for everyone. No joke.

Aprilaire / Generalaire 4040 Humidifier Solenoid Valve

I'm an HVAC technician, and have replaced dozens of these. Remember to order an Aprilaire 4004 In-Line Strainer and the correct orifice for your humidifier model when you order this solenoid valve, because it doesn't come with them. If you forget the orifice, don't be surprised when water starts gushing out of the humidifier, because the orifice regulates the amount of water fed to it. The strainer goes in the long end of the solenoid fitting, and the orifice in the short end.

Aprilaire 4231 Yellow Orifice: Aprilaire models 400, 500, 550, 550A, 560, 568 & 600.

#4021 Aprilaire Red Orifice: Aprilaire models 112 & 224.

#4232 Aprilaire Blue Orifice: Aprilaire models 350, 360, 440, 700, 760, 760A & 768.

#4007 Aprilaire White Orifice: Aprilaire models 110 & 220.

About a week ago I noticed that when my furnace was off...my Aprilaire humidifier just kept running. Well, to be more specific, the water flow into the Aprilaire was remaining on. At first I feared the control system in the furnace was failing to send the "close valve" signal. But a bit of investigation uncovered the culprit: the solenoid valve was "leaking"! When the furnace was running, it dutifully sent an "open valve" signal, and the solenoid fired as usual, sending water to the Aprilaire. But when the furnace shut off (and/or the humidity set point had been reached), the signal to "close valve" was properly sent, but the solenoid did not fully close. The water supply decreased, but there was significant leakage passed the seat of the valve, causing the water to run down the drain 24x7.

Option 1 was to call my furnace company and have them come replace it. My guestimate was $100-150 to make that happen. While they are normally worth every penny, in this case I struggled to justify spending that much for so simple a fix. So I started snooping on the web and found this replacement part here on Amazon.

I could not be HAPPIER! It took me all of about 10 minutes (and I am NOT a skilled plumber!) to swap out my old solenoid for this one, wire it up, and give it a try. It works PERFECTLY! Now, to be clear, you will need some tools. An adjustable wrench and screw driver are musts obviously, but what some people may overlook is you may need a copper tubing cutter. When I removed the old one, the old copper fitting would not fit properly in the new solenoid, so I had to cut it off and installed the new fitting that came with this valve. Other than that, installation was a breeze!

Let me clarify a few items that I saw mentioned in other reviews:

First, this solenoid DOES ALREADY have a strainer on the inlet! Do not waste your money buying a new one, as recommended in other reviews and as shown in the "bundle" in the ordering area on Amazon. The filter is built in, and in fact if you bought another, you would be unable to make it fit.

Second, this solenoid DID FIT in the exact mounting holes that the old one used. Maybe I was just lucky, but I saw others say theirs did not fit. Admittedly the tubing routing had to be shifted a bit (this solenoid is not the exact same size as the old one), but the mounting holes lined up perfectly.

Finally, YES you must use a yellow orifice (or whatever color is right for your Aprilaire) to restrict flow on the outlet... BUT before you buy one, take out your old solenoid and see if you ALREADY have one that is in good shape! I wasted a few bucks on a new yellow orifice when in fact the old one was perfectly fine and went right back into service with the new solenoid.

It remains to be seen how long this solenoid will last, but I am VERY happy with this one so far. With about 10 minutes of work I saved myself probably $100 in repair fees and now my water is not running down the drain 24x7!

This company does not ship what is pictured. They ship a cheaper imitation part from China. It will work but does not fit like the original. They should be ashamed of themseves for misleading people with what is described and pictured. I went with this company for all the good reviews and thought that I would get what was pictured to avoid the cheaper imitations. I will complain to Amazon but at least the part does work for now or at least the last 15 minutes as I just installed. I also gave them a 1 star for misrepresentation.

The HVAC company did a winter tuneup on our furance. They mentioned our Aprilaire 550 humidifer wasn't working and quoted $230 to repair it (including a new solonoid). I bought this solenoid and a maintence kit (pad, hose, etc.) on Amazon all for $70 including shipping. Simple 30 minute install and the humidifer is working like new again. You can't go wrong with this product if you have an Aprilaire 550.

I have a history of a recurring problem of the valve malfunctioning every year. The valve manufacturer is some outfit in Wisconsin and they charged almost $100. Sure enough, the valve failed again in one year. So this is the 3rd I have replaced. I will see if it lasts. One thing I notice is that this is heavier and a bit larger than the OEM valve. It is quieter and has a more solid feel to it. It fit the mounting fine on my Aprilair 440, no problems there. They do not give you a new in-line screen or a flow-reduction fitting, but all I did was turn the tap-in valve from my water source lower and that controls the amount of water flowing into the humidifier, so who needs them and why pay another $10? Works great. Its been 3 weeks and so far working fine. I'm hoping...

I did purchase this from Amazon.

[UPDATE]: This is my second heating season (2013) and this valve is still going strong, no problems with the valve or humidifier. As I said above, this valve is built much heavier that the original factory model. I am very pleased.

[UPDATE]: Finished my 2013 heating season, valve still going strong. I have saved $200 on OEM valve replacements. This is a great item.

Essick Air Products MAF2 Replacement Filter

This filter is hard to find, as the other reviewers state. It does not come ring shaped. Rather, it is shipped flat, with a couple of folds. You have to reshape it to fit in the humidifier.

Also, it is a tad small. You cannot form a complete ring with it. That probably reduces the dust reduction factor of the humidifier, which is one of advertised factors in the listing ("virtually eliminates dust").

However, since the original filter that came with the humidifier was a perfect ring of the perfect size, the customer is being short changed with this product. There seems to be no alternative to it, however.

Update: I recently (Mar 24) purchased two MAF-2 Essick Filters at homedepot.com less expensive and exactly the right shape and size. Fit easily into the humidifier just like the original one. So, I would say, get this only if the homedepot one isn't available.

If you want your humidifier filters to last longer, then use filtered water and an additive to the water to prevent bacteria, as well as mineral build up. We use Golden Solution Combination by Vista Solutions. And if you want to pay a much cheaper price for these filters, go to Lowe's and look for IDYLIS Universal filters. They are currently $8.98 each. We have an Essick Moist Air Humidifier model 12010, and these filters fit fine, though they are boxed flat and have to be shaped...

Unfortunately, I can;t get the filter in the local stores any longer. However, this buy was essentially fair priced, and filter works as usual. I like the humidifier, so I like this filter to help me keeping it running.

I've bought several of these, and they work, gradually collecting hard water minerals until they don't work any more, after a couple of weeks (depending on your water). The only complaint is they always smell bad when I first use them, so I break them in in a small closed off room.

I love my Essick Air humidifier, but am seriously displeased with the absurd price for these filters. The margins on something like this must be in the stratosphere. Also, I am beginning to question the design of the humidifier itself. It is impossible, especially given the use of water decontaminant, that the impurities that clog the filter simply materialize like magic in the water. They come from the room atmosphere itself. The degree to which the MA0800 is exposed is unnecessarily high and causes additional impurities to be pulled in by the inspiration of the fan, clogging the filter (which is not high enough to prevent these same impurities from being kicked right back out into the air) to just collect filth faster, leading it to clog and prevent the humidifier to function effectively.

The box indicates that the filter should be changed "once per season." This is nonsense. The first filter clogged to the point of basically rendering the humidifier totally ineffective after only a month. It worked flawlessly again as soon as the filter was replaced, but I'm pretty dismayed at having to order more of these things after such a short time. There is nothing extraordinary about the room I've got this thing in, nor is the water I'm using (purified tap) particularly hard. Within a few months, I will easily spend more on filters than I did on the humidifier itself. Pretty ridiculous and annoying.
