When I wake up in the morning, my sinuses are not stuffy. Here are some pros and cons of this humidifier.Pros:Warm and Cool settings-This humidifier has a warm setting and a cool setting. Since it is warmer now, I like to use the cool setting.Nice size water tank-The tank can hold 4.2L of water. This will give you 14 hours of use.Soft-Touch Button-You don't have to press hard to turn the humidifier on or off. One touch to turn it on, another touch will start the low humidifying level, another touch will start the high humidifying level, and the last touch turns the machine off. When you turn the machine on, it immediately starts misting.No water warning-The control panel turns red to let you know that the tank is out of water.If the tank is removed from the base or in case of pulling of the tank, the machine will stop working and will have to turned back on to work.This humidifier can be placed in an area of your choice and plugged in. Can be placed on a nightstand, floor, or wherever you choose.Automatic shutoffUnderneath the humidifier, there is a filter, aroma pad, and aroma box. The filter helps to keep the mist clean. The aroma pad can be used for and essential oil of your choice to give your room a nice fragrance.Easy to clean-just wipe down and your doneWide enough nozzle for the mist to come throughWhile on, it is not noisy. It runs quietly as to not disturb you while you sleep.Cons:Kind of bulky to fit on a nightstand. If you don't have a lot of space on your nightstand, so me things may have to be moved in order for the machine to be placed on it.The cap on the water tank did leak water so make sure that the cap is screwed on tightlyOverall, this is a great humidifier for your needs. Would be great to place in a baby's room or any room that you desire. My favorite place to place it is my bedroom so that it helps me sleep and works great at keeping my skin and hair looking great! ### ⭐⭐⭐⭐ Great unit, minor possible defect *by C***L on Reviewed in the United States on March 16, 2017* Good product. I like it a lot. It's very quiet. But you have to keep your eyes open for possible leaks and you should use purified water which seems to work the best for me. I wouldn't use tap water and distilled water doesn't work well for me either. Customer service was good but they were a little aggressive about wanting me to review the item. I don't review items ASAP. Also they initially didn't think the product occasionally leaked until another customer complained. They replaced the unit that leaked and they were friendly and tried to be helpful but I'm still on the lookout for leaks. I think it's a great humidifier and it helps my allergies and is very easy to use, but unfortunately you may have to check the unit every so often to see if it leaks. I use it everyday and I'd still recommend it. ### ⭐⭐ Not worth the price since the warm mist comes outs so heavy.... *by B***S on Reviewed in the United States on March 28, 2017* I think this is fine if you want cool mist, but I purchased this for the warm mist... Unfortunately, the warm mist comes out so strong and heavy that it leaves a massive puddle.... Not worth the price since the warm mist doesn't really work without destroying your wood floors or soaking your rug/carpets....If you just need a cool mist humidifier, you can buy plenty of cheaper ones on Amazon. --- ## 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.ie/products/38683732-4l-warm-or-cool-mist-humidifier-ultrasonic-technology-with-super](https://www.desertcart.ie/products/38683732-4l-warm-or-cool-mist-humidifier-ultrasonic-technology-with-super) --- *Product available on Desertcart Ireland* *Store origin: IE* *Last updated: 2026-05-31*
