AIRCARE 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

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.

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.

We have a cabinet-style AirCare humidifier that's been in use for almost a decade on our second floor and while it works well, with the temperatures dropping so much and with the heat being on non-stop it was getting defeated -- low 30's for humidity when we have it targeting closer to 50. Even with it at F2 (F1-F3 with F1 being low) it just couldn't crack mid-30's. Our downstairs was at a whopping 24% humidity and our house hates it -- seams appearing in the hardwood, drywall getting micro-cracks (plus SO MUCH static which the cats just love...). We got this delivered before the supposed big storm of 2026 and got it quickly assembled and filled. It comes with wheels which is perfect because I could roll it over to the kitchen sink to fill it vs. having to fill buckets, which is what I do for our cabinet model. There is some trick to aligning the filter correctly: it's pretty obvious that it needs to go into specific slots on the bottom of the humidifier but it ALSO needs to go BEHIND the slots on the sides, otherwise the filter will fall forward once the fan is on. This is covered in pictures in others' reviews but it's an important note that I missed at first (and was wondering why the humidity wasn't picking up much). Unlike our cabinet fan, the fan on this unit is sucking air in vs. ejecting it -- so make sure you don't have anything loose around the top or it will get ingested. The air is forced over/through the wick/filter and ejected through the front grill. Fan speeds: This unit, too, has three fan speeds; low is barely audible and you can hardly tell its on. Medium is loud but has a timbre that is grating to me and gave me a headache. High (what we set it on most of the time) is probably technically louder than medium but it's a low-pitch sound so is less disturbing. Again, our downstairs is ~20% humidity right now so I'm going for maximum effect over noise control. Blinking 20: I saw another post comment that their unit was broken -- this means that the humidity being registered is below 20%. Ours did this when I had the filter installed incorrectly and the humidity wouldn't go up. We opened an exterior door which caused the humidity to spike down and were then greeted with this. If your unit is blinking 20, either it's really dry where it's located or the humidistat is kicked (or being blocked). For anyone who hadn't owned a large humidifier before, these are not marvels of engineering -- they feel very flimsy and cheap; this is a feature not a bug. The containment unit is just there to hold water so the fans can blow air over the wicks/filters and get that water out to the space. If you're having to refill it regularly, it's working -- you may just have a very large space or one that's very dry. Remember that when you apply humidity, EVERYTHING that's porous will absorb the moisture BEFORE the air is able to hold onto it. If you are starting from scratch (low %) it will take DAYS to holistically improve (or you can buy multiples but these are expensive). Our first floor is at a solid 30% after 24 hours of running on high and our second floor, because less is being taken by the first floor, its in the lower 40's which is really our goal since this is where all the bedrooms are (plus the static). It does exactly what it is built for exactly the way it's supposed to so four stars; make sure you read and follow the instructions!

This has 3 fan speed levels. When it on level one, the noise level is super quiet. But level two is a different story. That noise level change is the only down side to this humidifier. The built in humidistat helps hold the humidity level. I need to fill about every 3 or so days but, the humidity hasn't been super low outside yet. Make sure the get some anti mold liquid. The filter that come in the unit molded pretty quickly. Not fault of the unit but, it will happen. **Update** The unit went into what's called control lock after 2 months. I followed online instruction and can't get the error to clear and the unit finally stopped working. Since I was outside the Amazon return window, I reached out to the seller who quickly offered me the number of the manufacturer to call so they could help me trouble shoot and possibly send replacement parts. Or, they offered a replacement unit, which I am taking them up on. I was impressed with the speed the seller reached out and hopefully, I have not received the new unit yet, solved the problem because I liked the unit when it work. We'll see if the problem was a fluke or poorly manufactured humidifier.

Update 12/2020: So a new problem appeared and is signaling that this is about to die. The display started showing CF and F alternating. The water is at a minimal level and when you lift off the top, the fan "should" stop as a safety. I lifted it and it's a good thing I had a good grip otherwise if my hand slipped it's would've been in the fan. Lawsuit waiting to happen. Upon more inspections, it turns out the switch no longer works and likely any other sensor so I'm giving it another month or 2 before it completely craps out. UPDATE 1/20/2020: So that didn't last too long. It was great when it worked and it kinda still is but waiting for the shoe to drop. I stopped it to refill the water and all of a sudden, F2 is making a large humming noise. F1 and F3 speed are still quiet...yet F2 produces a loud hum. How does that happen?! Anyways, I already tossed the box so I'm not happy about lugging this loose thing through a Khol's to return it. How embarassing! Besides that, I have to wait until I feel up to it since I am still sick. Wonderful! Back to searching for a humidifier, while Aircare makes units that cover a large area, I am not willing to spend another $110 nor $350 to risk another return. Original: My house has issues in the winter. The thermostat is downstairs and the heat rises to the vaulted ceilings upstairs. Colder days, the temp can be 10 degrees different than upstairs. Which also means the heat dries out the air big time. I tried stronger smaller units per room and that can't keep up. I worry about getting a whole house installed because of mold issues in the ducts and besides, the HVAC unit is in the attic and I am dredding regular service fees, another expensive filter to change, more attached units to possibly fail, also (this is a biggie!) constantly dragging out the ladder and climbing in and out of that access for regular maintenance. Hell no, if I can avoid it! Before calling HVAC and having a unit installed, I decided to give something like this a last shot. I read in articles that humidifying the air can help also retain the heat instead of that quick dissipating dry heat. So I got a weather station with 3 remotes that had hygrometers. The station was mounted next to the thermostat downstairs and one remote in each room upstairs, the unit was setup by the stairs so humid air can split between upstairs and downstairs in a 2300sq ft home. Here's what I found: Before: (outside avg 22 F, thermostat set to try holding at 68 degrees +/-1) - on the days that the heat struggled to keep up Thermostat temp was at 68-69, humidity was at 20% - Master w/ vaulted ceiling 76F, 9% - Guest - no vault 74F, 12% - Kid's room w/ vaulted 76% 10% Their noses bled frequently, first thing in the morning and sometimes later in the evening AFTER being on 1 full day at Fan 1 and some 30 min shifts F2 when noise is not an issue: (avg outside 24F, humidity 22%) - main room with thermostat 68-69F humidity up to 32% steady - Master BR at 71F and 22% give or take (no help from smaller room humidifier given) - Guest room 70F and 25% (no extra help given) - Kids room 70F and 23% (no help given) I can say, yes it did help. I can say yes, the theory of humidifying the air helps retain the balance out the heat. I am certain because last night I forgot to refill the water and it must've stopped, we were all dry again. It does come with casters that you put on if you want - just don't push it in hard because the tub is somewhat thin. Cleaning is easy to a point. It does have 4 raised points and some structural oddities that would need a q-tip or toothbrush to Lightly scrub out. Thats why I put 3 stars for that. My negatives: - I do agree with other readers, the reservoir is flimsier than I am comfortable with so I only put a few gallons at most. I would freak if 6 gallons spilled all over the hardwood floors so I am mainly concerned with that. This is the only reason why I would return this. - The fan can be loud. You expect some kind of noise level so be reasonable with the expectation. F1 - low is quiet enough. In a silent room, it is no louder than any large room humidifier. F2 and F3 - that's louder for sure. Comparable to one of those large room fans - the large reservoir probably help amplify it a little. Not a deal breaker IMO - just set it to F1 once you're at a maintenance point. I guess I will still look around to see, for now I will try it. If I don't see anything better then I guess I roll the dice with this one. If I see something just as powerful and sturdier, then I'm returning this. Again, the sturdiness of the tub is my biggest concern. Fill it quarter to half and I think it's ok. I'd be worried with a full tank.

What a great improvement on my well-used 12-year-old evaporative humidifier, which was bulky and had two water tanks, totaling in about 3 gallons I think. Placing them into the humidifier after refilling them became too backbreaking as I’ve aged, so it was time to get another. It still works so I’m giving it to a young family. This new humidifier is pretty light when empty and was very easy to set up; I just turned it on its side on my countertop to insert the wheels, and then set it on the floor. Another thing that drew me to this model is the large water tank that is so easy for me to fill. I just roll it over to my kitchen sink and pull out the nozzle, which is just long enough to reach the edge. If you have a hand-held shower nozzle, that would work too. As long as you are careful not to overfill — because it looks like it could hold a lot more water — all is good. Otherwise you will have water everywhere. Also, with a larger water capacity, I won’t have to watch it so closely. The buttons to control the unit annd level of desired humidity are easy to understand. Just reference the guide that came with it if you need help. I find that 40% or 45% is all I need, but you may want a different level. One more thing for people who are still deciding on the type of larger humidifier to get. Cold or warm mist humidifiers probably are better for smaller spaces or for places with lots of plants requiring more moisture in the air. Silly me — I accidentally bought a cold mist humidifier and within a few hours the surrounding area was just too moist (ok, there was a puddle) while the rest of my apartment didn’t register a difference. I returned it and bought the one I’m reviewing now. It’s an evaporative humidifier which has no visible moisture in the air when it’s running. It almost makes you wonder if it’s working, in fact, but if you have a humidity sensor you’ll see the humidity rise fairly quickly. When the unit senses the desired humidity level, it will turn off, then back on when the humidity drops a little. Typically, evaporative humidifiers have a filter that needs replacing about once a month. I hope this helps.

The first floor of my house is about 700 sq ft. Three of the rooms are open for good air flow. Two rooms are separated from the rest by door openings, restricting the air flow. Here are my results with the AirCare 6-gallon Space Saver humidifier in this environment, placing it at one end of the larger open space. THE GOOD. I recommend this humidifier (with reservations) for these two primary reasons: (1) It works. The humidity in my house is 16% in the winter. This humidifier can raise the humidity in the room where it's placed to 55% if I run it about 8 hours a day. I choose to not run it longer than that. (2) Energy consumption. This evaporative humidifier uses a lot less electricity than the Vicks warm mist humidifier I had previously, which was only effective in one small room with the door closed. (3) Customer service is good---quick and responsive. THE BAD (1) Noise. There are three fan speeds. F1, F2, and F3. F1 is very quiet, but won't put out a lot of moisture. F3 is fairly loud but it doesn't make that weird noise; it's just the sound of loud rushing air, which is OK if I'm in another room. I wouldn't want to be sitting in the room with the fan on F3. F2 is the problem: it makes a loud, uneven BUP BUP BUP BUP sound that I personally find intolerable even when I'm in another room. The frequency of the F2 sound is precisely calibrated to drill a hole in my brain. There are ways the manufacturer could overcome this, and it's disappointing they haven't done so given the number of complaints about this in the reviews. I contacted the company about the fan noise. They responded immediately and offered me a replacement fan, no questions asked. This tells me that they get this complaint frequently. The new fan they sent me had the identical problem even though the company told me they test all replacement fans before they send them out. This indicates that the noise problem is in the design and materials of the unit. Can the noise problem be overcome? To a certain extent, yes. When I first got the humidifier I ran it on F3 for two or three days until the walls and furniture absorbed enough mositure than the humidity level could be maintained more easily. Now I run it on F3 for the first hour in the morning and then I reduce it to F1 for the rest of the day. In other words, I never use F2. That's a big drawback because F2 is arguably the most desirable speed, balancing reasonable moisture output with tolerable noise level---IF all you were hearing would be the sound of rushing air, but it's not. There is very little difference in power consumption between F2 and F3, so if you could run it on F2 you should be able to get quite a bit more moisture output for quite a bit less noise, but the latter is not the case. I asked Rufus, "Why does the fan make so much noise on second speed?" Rufus answered: "The loud noise on speed 2 (medium setting) of the AIRCARE Space Saver Humidifier is a common issue. Multiple customers report this exact problem - speeds 1 and 3 run normally, but speed 2 produces a distinct loud humming or buzzing noise. Common causes include: Motor speed resonance - Speed 2 operates at a frequency that causes vibration in the housing. Fan alignment issues - The fan unit can become slightly misaligned, causing buzzing. Normal design characteristic - Some customers report this is typical behavior for this speed setting. Quick fixes customers have found: Gently tap around the housing sides to realign the fan unit. Place something with slight weight on top to reduce rattles. Use speeds 1 or 3 instead, which are quieter." (2) Coverage. I said that the humid rises to 55% in the room where the unit is placed. In the other rooms it gets to about 28%. Of course, you will have better results if you run it on high all day. My results simply show that the results are better close to the unit. For me, 28% is acceptable compared to 16%. (3) Difficulty filling. The design of the fill opening is poor. It's about 4 inches back to front and the same width as the front of the unit. I'd like to fill it with a 2.5-gallon bucket to reduce trips back and forth to the kitchen, but there is a significant risk of spilling water with a bucket that size and such a narrow opening. So I use a much smaller juice pitcher, which requires many trips from the kitchen each day. I don't want to move the unit on its casters over the wood floor to the kitchen, and once it's full, 6 gallons of water weighs 50 lbs---not easy to move a long distance back to the living room, with increased risk of damaging wood floors. (4) Cost of wicks. Natural Breeze makes a washable, reusable wick, but that's expensive too. There are instructions online for making your own wicks using reusable material available online and cutting it to size. (5) Difficulty and cost of maintenance (avoiding mold). Again, there are DIY medthods and subtances (e.g., vinegar) for cleaning the unit to avoid the expensive antibacterial additives. MY TAKE ON THIS UNIT. Buy this humidifier if you want something that's going to add several gallons of water to your house each day and you don't care about the noise, ease of filling, cost of wicks and antibacterials, or weekly cleaning. It does what it's supposed to do---just not conveniently. I considered returning it but I was desperate to relieve the dry air in my house so I kept it. If they fixed the F2 fan speed noise problem I would give this 4 stars, because problems like cleaning are common to all humidifiers. Redesigning the fill space would raise it to 5 stars.

I bought this in Feb. and it worked really well for our needs during dry winter months. Pros: Holds alot of water so less refilling. Rollers makes it easy to take thru rooms. Using a separate humidifier gauge the unit got the humidity where we need it and shut off when that was reached mostly. Easy set up. Easy to wipe out and keep clean. Cons: It is loud, o.k. on low setting however anything higher is way too loud to be in the same room with. The rack that holds filter is flimsy and a couple tabs broke off when I changed the filter. The filters are not cheap. When preparing to put it away is big and bulky to pour water out and filter takes forever to dry out. It is to have an Auto Dry out feature that never came on. The "humidity sensor" built onto the back on the cord isn't in a good place to me being behind the unit and only about 6" away from unit. PROBLEM: In April the digital display that you set for humidity control started flashing F 26 degrees. Never changed and so I started having to turn it on and off by using the gauge I had separatly. No idea why it changed in this way. Before just storing it away I called the Customer Service number and the lady asked me a few questions to test the humidistat and sensor. After a few steps she said I would receive a new unit as this is defective. VERY easy to deal with. I will update this review once the replacement comes as she said and I know what they want me to do with this defective one. I will either get Return Shipping labels or will not have to return it. So all in all if this is replaced and the new one works fine I would DEFINATELY recommend this unit for purchase. Mainly using Prime Shipping b/c it is very large. UPDATE: 4 days after contacting Cus.Service I received an entire new unit....so tho the unit was defective the Cus.Ser. was excellent, didn't even hassle about a Warranty card unsent. SO I WOULD RECOMMEND THIS UNIT AND SELLER!!

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.

Good Item very practical for all.

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