Pure Guardian H4750AR Ultrasonic Cool Mist Humidifier, 120 Hrs. Run Time, 2 Gal. Tank Capacity, 600 Sq. Ft. Coverage, Large Rooms, Quiet, Filter Free, Treated Tank Resists, Essential Oil Tray

I purchased a Pure Guardian Ultrasonic Humidifier in early 2019 because of the winters and dry heat causing my skin to be super dry and my nasal passages to bleed. The one I purchased then was manual and I keep it in the bedroom. Since it worked great, I wanted one for the living room so I didn't need to keep moving the first one I purchased. This Pure Guardian H4750AR Ultrasonic Cool Mist Humidifier is push button and has the cool mist only, which is totally fine. Amazon had the lowest price and I thought I would try it out to see if it was worth it. This definitely is! If you are looking for a larger capacity cool mist humidifier that is ultrasonic (meaning it does not need filters and gives an even mist) then this is a great purchase. I have been using it for almost a week and it runs all day and night. I fill it up and keep it on the highest setting. It is really quiet and as I stated, it is a nice fine mist. The Pure Guardian are definitely great products. The manual states it comes with a 3 year warranty.

This humidifier has been a game changer. It's easy to use, easy to clean, but best of all it is powerful enough to humidify our entire apartment. I refill the tank every other night but keep it running round the clock. As a singer, it has made warming up and maintaining my vocal health so much easier. I didn't realizer how helpful it would be. My boyfriend struggle with painfully dry skin in the winter and it has even helped him!! I did a lot of research before purchasing and I am so happy with my choice!!

I use this device often. It works best with distilled water, or reverse osmosis water, otherwise it creates white dust in the room. I wish there was a better way to adjust low, medium and high output to my preferred preference, not just the setting on the machine.

This humidifier has been running 24/7 for the past two weeks and there have been no issues. I live in Colorado where humidifiers are a necessity in the winter. The reason I gave it 4 stars instead of 5 was because when it’s full it’s heavy and clumsy to flip over and insert. Not impossible to carry, just awkward to lift and flip when it’s full due to the lack of convenient hand holds on the side. If it had a carrying handle on its side I would have given it 5 stars for ease of use.

It doesn't get 5 stars for easy to clean. BUT, NO small humidifier is easy to clean. Keep a toothbrush, a sprayy bottle of vinegar, and a toilet bowl swab, and you can clean any small humidifier. The alternative is to use distilled water, but nobody does that because at the end of the year, you would have spent more on water than on the humidifer. This humidifier works very well. It has great features, and shoots the mist out is several adjustable directions. I highly recommend it.

I really do regret purchasing these. I got two. First of all, they are nice and they are HUGE. My first complaint is the way it was made as far as filling the water. The top part sits on the white part and you have to separate the two and flip it (blue container) upside down and unscrew the cap to fill with water. There WILL be water on the bottom part when you lift up the blue container. It is not "leaking", but it is how it is made. So be careful when taking the container from the base because there WILL be water in the white container. This makes me mad for several different reasons. One, it make it so hard to fill it all the way up and flip it upside down to put back on the base. If you fill it all the way like I do this is heavy to have to flip over to place it back on the base. I have pinched my fingers. Second, the water that lays in the base once removing the top can cause mildew and moldy water. Nobody likes this.. yucky! So, it is probably best to not fill this thing all the way up since you WILL need to clean it often. Preferably after every use. Now, the cleaning part is very hard. I can get my hand and arm into the tank but not all the way through it to scrub it. I would suggest using a baby bottle cleaner wand or something to get in there good. Another thing that makes me mad is the white dust this thing puts off on my furniture. I was reading this CAN be dangerous for your lungs and cause more issues with health. This is a tank you will want to set on something and not the floor or the entire area will be soaked! But whatever you lay it on will have white "dust" after one use. And lastly, the smell the tank puts off? I do not know why it has an odd smell, but it is almost chemical like? I do not know. But someone else who has it will most likely know what I mean. I got this for my toddler because our gas furnace is very drying to me and him. It doesn't bother my husband much, but the child and I get pretty dry. I got these at the end of winter to see if it would help the dry cough my son was getting. It made it worse! I had to stop using this for him. This is upsetting because have you seen the price of these? I got two... Keep in mind there ARE good features about this though. I love, love, love the night light it offers especially for kiddos. I loved the size of it. I loved the mist it puts off as it does create a large mist to reach a good size room! And lastly it is VERY quiet! It does make a water bubble noise every once in awhile as the water slowly gets used up, but not enough to wake you up unless you are a super light sleeper. I did however get a "refill tank" error when I had just filled it and it wouldn't work unless I put the setting on "low". After that day it never did it again (so far). I really do regret buying these and if I still had the boxes of them I WOULD return. To me $89 is to much to just throw away! If you do not mind anything I said about them, by all means give it a try as it could just be (me). But, if you want to try it out, I would suggest not making my mistake and hold onto the box. And normally I do, but I just didn't this time. I had high hopes I guess. Almost forgot: It does have an essential oil tray, however it is in the back. To me this is all wrong. I do not see how this distributes the oil into the air when the mist doesn't even touch it... I smell the oil for a few seconds and after that I do not smell anymore.

Excellent product - easy to use, well designed and attractive - but of course the biggest and most important thing is that it makes a lot of cool mist humidity. The tank size is perfect - large enough to generally run 24 hours, but not too unwieldly to fill. Easy to recommend - you won't be disappointed.

Nice humidifier. It looks pretty with the light on or off. Works well. Love everything about it except filling it. It is a little noisy (water sounds) and it is a terrible design to fill. The top has a rounded metal spin device where the mist comes from so it doesn't sit flat in the tub or sink when you flip it to fill it. There are two little handles to hold upright or while it's flipped upside.
