Review: Excellent Product - Don’t Forget The Spout! - EXTREMELY IMPORTANT! When you unpack the box, there is a small package with a spout cap and brush. These are both critical pieces. Do not be tempted to use this machine without the spout - if you do, everything around the machine will become drenched quickly. I couldn’t be happier with this humidifier. The tank is big enough that it lasts through the night, even on the upper power levels of the dial. Out of the box, it’s very easy to set up. I cannot stress enough the importance of the spout cap though. It comes in a small packet and I assumed it was either an enhancement or possibly to be used for storage. Nope! If you turn it on without the spout, you will be enchanted by the massive puffs of lovely humidity coming out and think that’s all you need. But the fact is that huge clouds like that are heavy - too heavy to float away from the machine. They settle and condense immediately and very quickly, you’ll have a pool of water; not only on the surface you’ve set the machine on but it will soak whatever fabric might be nearby. The spout not only prevents this, it’s remarkably effective at directing the mist and pushing it further away from the machine and higher into the air. The provided brush is marginally useful for cleaning the rubber inside parts. But be sure to do this, especially if (like me) you choose to ignore the warning not to use essential oils or other non-water liquids. About adding oils: The oils WILL erode the plastic tank and fan mechanisms or even clog the wet wicking filter. There is product called Vicks Vaposteam that seems to be more effective and safer. My research shows that it’s less damaging to a humidifier because it has a high alcohol content so it evaporates and doesn’t clog as much. Edited to add: “Doesn’t clog as much” means it still clogs it. The oils WILL gunk and clog up the parts, sooner than later. I learned this very literally 3 minutes after posting this review. I looked over at my adorable little humidifier lovingly and noticed the bright red placemat I’d set it on was…maroon. Lifted it up and discovered it was saturated. Not because of a defect in the product, but a defect in the user. I’ve been adding nasal passage clearing oils to help with a cold and didn’t clean it out before adding more to the next water refill. Sure enough, because it’s a cold mist humidifier, the oils sank to the bottom and solidified near the drain. Backed the whole thing up. It took boiling water and a toothbrush to scoop the goop. About cleaning: Especially if you add an oil but even if you do not, debris and gunk will collect at the bottom of the tank by the rubber parts and wiping them away doesn’t get everything out. Oil will attract even more gunk and can very easily create molds and bacteria’s which, if you don’t clean out, will spew into the air with your mist. This really has been a great product and value - I plan on ordering a couple more for the holidays.
Review: Effective and Reliable — Just a Bit Tricky to Refill - I bought the AquaOasis Cool Mist Humidifier (2.2L) about two to three years ago, and I’ve been using it ever since. It’s been extremely reliable and powerful. The mist output is strong, and it easily runs for 8–10 hours depending on the humidity level setting. While it doesn’t automatically adjust based on room humidity, the adjustable knob works great — it lets you control exactly how much mist you want. It does an excellent job of maintaining comfortable humidity levels even in larger rooms. The only downside is the refilling process. You have to lift the top portion, unscrew the cap at the bottom, flip it over to fill with water, and then reassemble it — which can be a little inconvenient. Because of that, we usually refill it just once a day. Overall, though, it’s a durable, effective, and quiet humidifier that’s served us well for years. Highly recommended if you’re looking for steady performance and great mist output!

### ⭐⭐⭐⭐ How do I use the warranty?
*by A***R on January 17, 2026*

Good unit. Quiet. How do I activate the warranty as ours stopped running despite multiple cleanings? Amazon ad says to contact the seller (Amazon) or see the manufacturer’s website, but there is nothing on that website. I have the warranty confirmation. I’m feeling like the warranty is not real.
