Reviews of HONEYWELL/ENVIRACAIRE HAC-504 Replacement Filter Pad

Is there anywhere to buy the old filters without the blue wrapping.

I have used Honeywell Humidifiers for many years and never had the smell / mold problem you do with these filters, they are downright unhealthy.

I tried to rate these zero stars they are that bad but the system would not let me.

Please go back to the old filters

Bought a bunch of these replacement filters (10, I believe) for my Honeywell 2000 series humidifier.

This "enviracaire" blue wrapping was a new thing for me. HONEYWELL/ENVIRACAIRE HAC-504 Replacement Filter Pad Never seen it before, but figured what the heck, maybe it's new technology & will improve the filter's capability.

WRONG!!

My experience has been just the opposite. 1) It doesn't last as long, working only 2-4 weeks before it's efficacy diminishes, whereas the 'older' filters with the plastic/wire mesh would easily last 3-4 months, sometimes longer depending on use. 2) Using the old filters, I would often take them out after some heavy use, clean them, and descale them before continuing to use them. Only after months of use & hard build-up would they lose their efffectiveness & need to be changed. With these "enviracaire" filters the build up isn't heavy at all, it maybe something else (see #5 below), they just lose their effectiveness very quickly.

3) I've been using humidifiers for nearly 9 years. I have a wine cellar & walk-in humidor, and for those of you who partake in those hobbies, you know how important it is to maintain proper storage conditions. So you might say that, yes, I do have experience in the use of humidifiers and environmental control. 4) I bought my last batch of (these) replacement filters from KAZ. When I began using the filters & encountering problems I contacted kaz to complain. Well, the customer service person who contacted me proceeded to tell me how it must be MY HUMIDIFIER that's not working properly as the filters work fine in hers! RIGHT!!!!! Does she use hers as extensively as I use mine?! I've been using the current humidifier(s) for three years with no prior problems to this!!!

5) Now here's the worse part, IMO. WHAT'S WITH THE FILMY/MOLDY STUFF THAT BUILDS UP?! When I began using these "enviracaire" filters, I began seeing a filmy, moldy build up in my humidifier's water system. Even after I thoroughly clean the filter housing & install a new filter, at about the 2-4 week mark (when the filter's efficacy starts to diminidsh), the unit gets this filmy/moldy build-up in the filter housing compartment and in the water (but it doesn't get into the tank). Whether I use a few drops of a bacteriostatic or descaling in the water tank or not doesn't make a difference. Never seen that before, never seen it with the older filter types!! This filmy stuff may be the reason for the decreased function of the filetr, at least that's what I suspect.

So! Should you buy this filer?

You decide. Personally, I think that the manufacturer needs to know about these problems and take care of them.

As for me, I'm trying desperately to find the older style filters that had a wire-like/plastic outer mesh. Honeywell HAC504 Replacement Humidifier Filter They seemed to work just fine!!

I've noticed a bad smell when I use these filters after only a few days use. The old ones without the blue air purifier didn't smell like this. I will not use these again even if I have to buy a new humidifier when I can't find the old HAC-504 filters.

This replacement filter suddenly began to emit a really foul odor. I soaked it for ten minutes as per the instructions but when I put it back in, the odor came back and my eyes started to burn. I realized I had to throw the thing out, which means I have no humidifier while the air is now very humid. Meanwhile I had to open the windows, with the temperature about 10 degrees outside, to get rid of the pungent odor and the sensation in my eyes still not gone, several hours later. They need to re-do this filter, it is a Zero.

Best Evaporative Humidifier Stainless Steel 15 Gallon Deals

Customer Ratings:

In my quest to replace the fake woodgrain 1970s-vintage Sears whole house humidifier that we've used for years, I first purchased an EssickAir (Bemis) TD6-710. The unit had all the looks, size, and features we wanted a really slick machine. The only problem was that it was severely design-flawed.

There is nothing on the market as sleek-looking as that unit. It's sad that it is so flawed. The hardware store was gracious to take it back used and unboxed, and they decided to return all 3 units they still had back to the manufacturer.

Wal-Mart had the Boston Innovative Products EH-01-342 for $109, so we picked one up. This unit doesn't have the electronic humidity meters, out-of-water indicator, or super-easy refill of the EssickAir, but it is solidly built and so far does not overflow the water basin like the EssickAir. There are 2 two-gallon containers in it for water. Each has a handle for ease of carrying. Getting them out involves removal of a pop-out screen in the back of the unit, so you don't have the convenience of frontfill. The 3-speed evaporator fan in typically noisy, even on the lowest setting. Cold air blows out the front of the unit, making placement of it in the room a concern of comfort. The unit is taller but narrower that those boxy larger units, making it a little less invasive. Time will tell how it fits into our home. I may update this in a few weeks with further experience.

2-1-07 Update

After using this machine for a little while, one thing I cannot understand. Why doesn't it have an out-of-water indicator? It seems crazy that you have to attune your ear to the mild grating noise that indicates a water refill is necessary. Why put the water pump through all that excessive wear? Another thing that can be annoying is the short cycle time. I don't know how the humidity sensor is set up, but the unit turns on for a few minutes, turns off for a few minutes, turns on for a few minutes... why not design a delay in the timing so that it wouldn't be so jarring with all this cycling? I'm thinking now that a 3-star rating is more appropriate, although it still beats most of the competition that I have tried.

We purchased this humidifier at WalMart when they were clearanced last year and got them out of the attic for this winter. First of all I don't understand how it can be called a "15 gallon" humidifier when it really only holds 4 gallons can anyone explain this? Also, we have also had problems with knowing when to refill it until the humidifier starts making a funny noise (and this surely isn't good on the machine to constantly let it run out of water). Also, we have had a funny substance running out of the machine almost from the beginning of use, and today while wiping up the "junk" I noticed that it is green now. ???? Anyway the reason I rated it a '2' is because it is nice looking and does run 'fairly' quietly when it is full of water. Overall, our family has been very disappointed in this humidifier.

I'm a new mom and I can pay for anything that good for my baby.

I bought the Germ Guardian H1000 Ultrasonic Table Top Humidifier month ago.

Love the design, not too heavy to refill the water.

However, after been using it about a month, one day, the red light came up at front, so it's time to refill the water.

I picked the blue toppart up then the blue light inside went off and I smelled something burning inside of it. I thought it was ok to use it without the blue light.

But NO !!!!!, right after fill the water and put it back. It's not working any more.

Maybe I got the defect one, but I wouldn't recommend anyone to buy it.

I would stick with other bulky humidifier which is a lot safer.

I first saw the Germ Guardian H1000 on the desktop of a co-worker. I searched the web for it and found the best price at Amazon. I originally bought it for work, but set it up on my nightstand to test it out and liked so much it never made it to the office. (I may have to get a second one for work.) It's compact size and efficiency are real selling points. I even used it in a recent production I was in, taking it to and from the theater every night. Most of the other performers in the cast wanted to know all about it and were also impressed. I highly-recommend it.

I was very disappointed with this product. Initially, it appeared to be exactly what I was looking for. A small, attractive, filterless humidifier for a baby nursery that had natural antimicrobial properties.

Prior to purchasing, I read a number of online reviews. Like most products, there were mixed results, but overall the impressions seemed positive. I had read a review by Paul here who claimed that the product didn't work. I assumed his review was hyperbole. Turns out Paul was right. It just plain doesn't work.

We ran this humidifier in our baby's nursery for 16 hours straight (refilling so the tank was never empty). In 16 hours, the humidity went from 33% to 34% !?!? It just plain doesn't work.

Now, I should also state some obvious stuff. We used the product in what should have been an appropriate environment. The room is very small 9'x9' and the door was closed to eliminate loss of humidity. Also, my experience can not be explained away as a single faulty unit. I had ordered two (another for the master bedroom), so we retested with a second model with identical results. Both produced a visible mist immediately above the unit, so they were 'working'.

This product has great features in theory. I was excited by the nano silver technology which in theory should make for a clean and low maintenance experience.

I returned this product and purchased a well known brand. While it didn't have all the flashy features of this Germ Guardian, it just plain works. I installed it 10 minutes ago and the room humidity has climbed more than 5%.

Bottom line. This product doesn't work. If you plan to purchase it despite these warnings, make sure you keep your receipt for the return.

This is a tiny humidifier! I bought it for my son as he suffers from bloody noses at night. We live in Arizona and it is very dry. We have the full size Germ Guardian on our side of the house and we like it but I thought the lights would bother the boys at night. So we ordered this. It puts out a small amount of steam and only lasts about 12 hours in our very dry house. But it seems to be enough for my boys. The unit does get warm and doesn't turn itself off when empty. It has a light inside which makes the unit glow a very pretty blue which is a great night light.

I've been using the Germ Guardian H1000 in a small bedroom (approx 150 sf). It doesn't really seem to work! I've measured the humidify before and after and it really doesn't seem to change significantly. It's small, quiet and cute but what's supposed to be most important is how well it works. And it doesn't.

I was first very impressed by the reviews I read and liked that this humidifier is so small.

However, it is surprising to me that no one has mentioned the missing research yet when it comes to the nano particles that not only clean the air this humidifier blows out but also may be a health concern!

"A 2005 study in Environmental Science & Technology showed that zinc oxide nanoparticles were toxic to human lung cells in lab tests even at low concentrations. Other studies have shown that tiny silver particles (15 nanometers) killed liver and brain cells from rats. "They are more chemically reactive and more bioactive," Illuminato says, because of their size, which allows them to easily penetrate organs and cells. "Products should be at least labeled so consumers can choose whether they want to be part of this experiment.""

.

There is not a lot of information out there for consumers to really understand the possible impact of nano particles in the air (and in food and clothes), and in the meantime, this technology is being used like x-rays in shoe stores at the turn of the century!

As much as I wanted to like this humidifer, I also don't want to be part of a study in 10 years....good luck to everyone else!

We were in the market for a humidifier for the winter months due to sore throats/dry throats at night. So we purchased this unit. I've read reviews on other products and most of them did not give a clear enough why it was either bad nor good. So we figured might as well give this product a whirl being the price was right and we could return it at the local Target store.

To our surprise this unit works as intended albeit the unusually loud fan (even on the lowest setting). But to us the white noise it generates is actually welcomed in our bedroom. It's not any louder than my custom gaming computer fans that i leave on running at night. This product is used in our room which measures 17ftx17ft. The air humidity at night is just right now. For the first time in the winter months me and the wifey got good sleep!! we both woke up with no sore throats or dry sinuses!

So in short review here are the PRO's and CON's

PRO's : Works as advertised. capable of humidifying a room of 17ft x 17ft with ease. Water tank holds a good amount of water. Run time on it is 16hrs filled. Easy to fill tank. Easy to clean. Comes with 2 extra filters.

CON's : Slightly loud fan (if you like white noise at night) then this would be a plus :) Would be nicer if it had one more lower level for the fan speed for the people that complain about the slight noise.

This product is worth the price! would recommend it to anyone looking into a Humidifier for a bedroom or a living room.

This humidifier is essentially 3 pieces: the reservoir, the actual "unit" with the fan, and the base. A paper filter sits inside the actual "unit" with the dial, and sucks up water from the base. The fan blows on the wet filter and voila: humidifier.

The fan itself is fairly noisy much like a desk fan. You have the option to select low or high on the fan, and select a month from another dial which is completely useless.

The worst part about this unit is the fact that the filter lasts for about a week before it starts reeking. It is like your kitchen sponge, the stagnant water in the unit and the wet filter is a breeding ground for bacteria. You get 2 filters, but you'll go through them very quickly.

I purchased this last year and it worked fine once I figured it out. At first it would shut off after the first of the two tanks emptied. I thought it was broke. However, the trick is that it needs to be leveled out just right such that second tank can kick in after the first tank is empty. This took some experimenting with shims under the left side front wheel. It's an interesting design. The two tanks are offset such that the right side tank always empties first. But, if the unit is not leveled correctly the second tank will never drain. Actually, even if this is the case it will still "work", you'll just find you are constantly filling the first tank.

OK, first a few basic physics things you should realize about humidifiers.

1) They move lots of air.

2) They handle lots of water.

Given the above, they are going to get dusty and want to grow mold and mildew.

That is just the way it is and ALL humidifiers of this type (cool air) will

have these issues. The heat type have their own separate set of problems,

not addressed here as this is not that type of unit.

This means two things:

1) They need complete cleaning regularly

2) They need new "filters" (actually moisture wicks) regularly

So this unit does work and gets the room it is in reasonably moist.

The unit is able to raise the humidity by about 5-20 percent. 20 close to the unit,

5 further away. It is way too noisy on the high setting, quite nice on the low setting,

OK on the middle setting as long as you do not need to be in that room for a long time.

I have found that after about 2-4 weeks the filters will need to be replaced so factor that

into your cost.

A big tissue is that as with way too many products, this (and I suspect most alternatives)

have lots of nooks and crevices and crannies that are a total pain to clean very well. If you

want to get this unit really clean, plan to take it outdoors, use a high pressure hose on the

non-electrical parts, and partially disassemble the fan housings (thereby involving electrical

parts so be sure you know what you are doing). A complete clean can take 45 minutes to an hour

of work but you will not get it clean without the effort. Also plan to do this every 2-4 weeks.

Bottom line, works OK but is a pain to maintain. OTOH, I doubt the alternatives are much eaiser

just a fact of life with humidifiers.

Update: I have stopped using this on reccomendation of my pulmunologist. He says that this type

can spew fungus into the air. In addition, after checking the humidity in an adjacent room with

it running and then again after not using it for two weeks (similar weather, BTW), there was only

about 4-5 percent difference in humidity. I strongly suspect that if you want good whole house you will

need a unit built into your house's HVAC system.

Another customer had a bad experience with this humidifier, but mine has been great. I got it online and it arrived in good shape and works well, with no problems for the last three years.

I got it to keep my acoustic guitars properly humidified in winter and it does the trick nicely. Set the humidity at 35%, fan on low and it works well keeping the whole downstairs of our 1900 sq foot old farm house properly humidified. My wife says it makes the house more comfortable in winter.

My only issue is that when the filter gets old (2 to 3 months), it grow bacteria, smells like a fish tank and blows that stink all over the room it's in. (I haven't tried the antibacterial water treatment.) So you will need a supply of replacement filters onhand.

It also needs to be refilled about every 24 to 30 hours when the humidity is especially low and the unit runs alot. It's a bit of a chore adding water, but it's worth it.

It needs to be pretty level or else you will get an error message, which is a bit of an issue in our old house where the room it is in (music room) has slanting floors.

On the upside it does not produce the powdery film on everything that you get with a misting humidfier if you have hard water.

Honest reviews on Essick Air HD1407 Whole-House Humidifier, Black/Honey Oak

We purchased this humidifier to use year round (we moved to Nevada) and have used it daily for the last 6 months. The 2 tanks are fairly easy to carry, and are easy to fill. This system is much easier than bringing the entire unit to the sink. For the setting and the lack of humidity in the desert I need to fill them every day. We have had to change out the filters twice so far, and as long as you are gentle with installing them, there are no issues putting the new ones in. (we have very hard water, which does deposit minerals on the filters requiring replacement) The fins of the filters are glued on one side so that they flex to fit the holder.

The actual humidifier has 3 fan speeds and is quite accurate in measuring the humidity output. If you place the unit at a central location, or near an air intake for your HVAC system, it does do the entire house up to 2000 square feet. It can be cumbersome to clean out the interior of the unit which holds the 2 tanks (there is a left and right tank), and there seems to be no easy way to clean off the fan blades.

The molded plastic used in this unit is by far the lowest quality I've seen on any home appliance sold in the United States. Much of it is precisely the same consistency you find in the 25-cent plastic toys that come out of gumball machines at the laundromat. No, I'm not exaggerating.

The very weakest plastic in the unit is the flexible housing for the filters. Ours arrived with one, the left, twisted out of shape. The filters themselves, banging around the unit during shipping, had broken "glazing" -the little plastic strips holding them together.

The moving parts controlling the emptying sequence for the tanks are also made of abysmally poor quality plastic, which is why it failed almost immediately. Although my floor is perfectly level, the right tank (my right, when facing the unit) fails to empty unless I literally jack the unit up a couple of inches.

The design of the machine is excellent. It's a very efficient evaporative array. Properly manufactured with metal framing -or at least a decent quality polymer -it would function reliably for many years. Alas, there's absolutely nothing like that available in the American marketplace, and we have only ourselves to blame. It's the product of an ugly business model that not only erodes the quality of the consumer goods we buy, but steadily impoverishes the US by ensuring that most of our productive assets and consumer expenditure flow overseas, often to nations inherently hostile to our own interests.

The marketing literature for this unit says it is "assembled in the US with imported components". In other words, all the value-added takes place in some Chinese factory, where disenfranchised laborers earn $120 a month working 60-hour weeks with no benefits, using energy and other resources subsidised by the Chinese govt. What little production takes places in the US is low-pay, low-skill and unlikely to make any substantive contribution to economic prosperity. The company itself is at the mercy of the giant big-box retailers (and now, Amazon) that channel our sovereign wealth abroad, with only a few senior managers earning a middle class-wage, while the CEO and CFO earn millions.

It's an embarrassment. Think about this the next time your congressman champions "free trade".

Honeywell/Kaz Home Environme De-Mineralize Cartridge Dc Humidifier Review

This filter, works very well with the humidifier we have, but the instructions are not clear on everything you need to do to make it work well. It has to be soaked for 15mn and then thoroughly rinsed so that it works properly. If you do not rinse it,the humidifier shoots a not very pleasant yellowish mist that fills up the environment. Other than that, it has been a very good product.

If you have a humidifier, it would be unwise to pass up using a demineralization cartridge. It saves you the headache of nasty gunk and mold that builds up in your humidifier. I agree wholehearted with other reviewers about the benefits of using this cartridge.

For the first one that I used, it lasted me about 25 or so days (or in short, I noticed little in the way of gunk buildup during that duration of time) before I felt the need to change the cartridge. My second one lasted about the same amount of time as well.

I have to point out, it is very important that you soak the cartridge thoroughly before adding it to your humidifier. For me, after taking it out of the package, I soaked it in a bowl of cold water for about 15 20 minutes before taking it out for use and so far I've had no problems whatsoever.

If you want to save yourself some headaches, I strongly recommend using this product in conjunction with your humidifier.
