PureGuardian 13L Output Per Day Ultrasonic Warm and Cool Mist Humidifier, Large Room, Home, Office, Bedroom, Silver Clean Treated Tank, 3 Speeds, Timer, Auto Shut-Off, Pure Guardian H4810

This is the second humidifier we have by this brand and, unlike others, it is reliable, effective and quiet (not silent, as that's not possible but barely perceptible). It also does a good job of staying clean much longer than others. I've recommended it to family.

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.

This is a nice quiet unit but they don’t tell you that because it is an ultrasonic and not an evaporative humidifier that it reacts with your gas stove flame. If you buy the filter (not included), it fixes the problem. We thought we had a problem with our gas stove as the flames on all the burners turned pink/orange. After calling our gas company, they asked if we recently started using a humidifier, which we did. This type of humidifier releases small mineral particles into the air from the water, which causes the flames to be the less efficient pink/orange rather than the normal blue flame. It is not dangerous but it is less efficient similar to when a pot boils over and the water hits the flame. One YouTube video poster said to use either distilled water (demineralized) or buy the filter. I opted for the filter and within hours, problem solved. This is something that should be noted in the description and instructions so people don’t spend a lot of money on a gas company service call. Other than that it works great on both warm and cool mist.
