PureGuardian H4810AR Ultrasonic Warm and Cool Mist Humidifier for Bedrooms, Quiet, Filter-Free, 120 Hr, 2 Gal Treated Tank Surface Resists Mold, Pure Guardian Humidifier with Essential Oil Tray

Can't hear it at all all night long and it's right next to my bed. I have it on about 3 or 4 output level. Two gals of distilled water lasts a few nights. I make sure my hands are clean when unscrewing filler cap to cut down on bacteria. I plan on buying more 32% hydrogen peroxide and adding a few drops occasionally to prevent any baddies from forming. Last time I bought some it came in about a quart bottle and also a blue glass bottle with an eydropper. That stuff works great but must be handled with extreme caution. Especially dangerous to the eyes and WILL cause loss of sight if contact with eye is made so be warned. Bleach does the same thing but I hated the smell and my eyes were burning a little the next morning when I only added just a few drops to a gallon. Won't be doing that again but it does prevent baddies from growing in the water. Anyway, this humidifier works fabulously compared to my Homedics two gallon unit. Don't get me wrong it is great too and their customer service is very good too, as they sent me a brand new one after my almost two year old one started leaking out the bottom. It runs much louder than the Pure Guardian but the mist comes out more robust than the Pure Guardian because of how the mist exits the unit. If Pure Guardian didn't have a double exit for the mist it would probably be as robust as the Homedics. Both are easy to fill and clean and each holds two gals but for quiet operation the Guardian wins hands down. I run them both for eight hours a night one on each side. Both have warm mist setting as well as cool. The Homedics makes gurgling sounds all night long so I use earplugs. I'm a light sleeper so that helps me a lot. I can still hear my alarm go off to get up, but they muffle the gurgling and I sleep like a baby. On these hot summer nights I run the air at 77 degrees and the humidifiers add just the right amount of cooling to the air to sleep well. Highly recommend the Pure Guardian as well as the other if you want to combat the dryness air conditioning naturally causes either in summer or especially in winter when the heater really causes dryness of the air. The scented oils don't really kick in much on either for very long and that's probably due to it being so passively introduced on its little "shelf drawer" with a saturated pad. It's too bad the scented oils can't be injected into the mist more positively but that's how these are made. I guess they have other ways of doing that, like a bowl with a light under it or something. When filling reservoir I just flip it upside down on the bed and pour in. Then I snug the filler cap not too tight and grabbing the handle in my right hand, cradle the bottom of full reservoir in left hand while placing it into position. Never have any problems. Read reviews where people complained about it's too heavy. Or the cap didn't screw on right and it spllied all over. Some people just don't have any basic motor skills I suppose. Regardless, this humidifier is worth every penny in my opinion. Looking forward to years if service and never repeat never will I put anything but distilled water through it. Heard too many whine about white dust forming on nearby surfaces I guess from mineral deposits. If you're going to afford the luxury of one of these, you gotta feed it right. Shame there isn't a way to distill your own and save money but if anyone knows please don't hesitate to let me know. Hope this review helps your decision.

I bought this humidifier as a replacement for an old Slant/Fin I'd had for several years. This has warm mist, which was a priority for me, as my old one also did. The biggest difference between the two is the noise-- or rather, the lack of noise of this one. I had gotten used to the Slant/Fin noise, which I considered white noise to sleep by, but this one is so much quieter that I'm amazed that I was ever able to ignore my old unit's noise. I was pleasantly surprised by the efficiency and ease of the humidifier. It does everything I want or need. The only downside, which has been mentioned in other reviews, is that this can be a little difficult to manage when full, not because of the weight (because all models with the same capacity will weigh roughly the same), but because there's only a handle grip on one side, so when it's full, it's a little unbalanced. This is a minor complaint however-- and the humidifier's operating features (which are, after all, intended to add humidity to the air) far outweigh the slight inconvenience of its handle.

I love the option to be able to turn on and off the light as well as increase the flow of humidity and the warm mist option. It is completely silent even when it's at the highest output. It is pretty easy to clean but I also add a little bit of hydrogen peroxide to my water to decrease the possibility of any mold growing inside. I also have had to use a butter knife to scrape off some of the white dust from hard water buildup. We've been running ours almost daily for the last couple of years and it has been great! My only complaint is that the wafer for the essential oils was in a different location so you could actually smell it coming through the water.

We have one in our bedroom to humidify the very dry winter air. It works quite well and I have but one issue: it's very awkward to fill the tank. You have to turn it over, remove the cap, and hold it under a faucet (e.g., tub) to fill it. Then, refit the cap onto the tank (which is now heavy and hard to handle), turn it over (spilling a bit of water) and carry it to the base. I don't want to sit the over-turned tank on the the bottom of the sink or tub because I'm concerned about damaging the nozzle that directs the steam. I knew all this when I bought it, so I can't fault the manufacturer. Otherwise, this is an excellent humidifier once filled.

Let me start with : I have a terrible cold. My husband gave me HIS cold. We bought this humidifier thinking that it would make us feel and breathe better. Wintertime is awful stuck inside your home because of heavy snow outside. This product is sitting in our living room and works beautifully!!! WE CAN BREATHE a lot better . It's easy to read for directions and it has 3 settings for release of humidity from it. We have it on number 2 which is enough for our tiny living room. It is not small and holds a lot of water. We use distilled water in it. My plants inside are even healthier. You won't be sorry by ordering this product. It WORKS and there is no noise at all from it. Thanks for making this product.
