Planned to return, but past the return window.Pros:a) beautiful designb) big bucket for water; comes out easily, and is easy to fillCons:a) no way to disable the blue lights, even in sleep mode. resorted to placed cardboard/books in front, which takes away from the beauty of the design.b) very difficult to start: took 5-10 attempts each night, with it often erroring out. went through all of their troubleshooting steps many, many times. would always eventually work, just was a huge pain.c) would error out and stop in the middle of the night in sleep mode. still full of water, just would stop running.Ending up being too much of a pain to run through troubleshooting steps, taking out & replacing, resetting, turning on/off, etc each night that we just stopped using. ### ⭐⭐⭐ Bad Design *by C***S on Reviewed in the United States on May 26, 2019* I've not had it long but I love it. Great design and top fill is awesome. Nice led controls, the programmable humidity sensor is a nice plus. Longevity is my only concern but so far would highly recommend.Update: well it didn't last long. After third refill it leaked the entire gallon on the floor.Returning. ### ⭐⭐⭐⭐⭐ Great purchase! Just a little tip... *by B***A on Reviewed in the United States on July 2, 2019* This humidifier is very neat, the ability to see the humidity level and keep the humidity at whatever percentage you want are very useful features. It’s super easy to fill since you can remove the reservoir. It has a sleep mode, where the light is dimmer and it hasn’t bothered me. The humidifier stopped working efficienctly, because I had been using tap water. just splashed a little bit of vinegar into the water and let it run for a bit and it was good as new. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/125422359-koios-humidifiers-for-bedroom-upgraded-4l-advanced-easy-clean-top](https://www.desertcart.sg/products/125422359-koios-humidifiers-for-bedroom-upgraded-4l-advanced-easy-clean-top) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-10-28*
