Q: Will there be mineral deposit buildup ?
submitted by DJohn49 - 1 year ago
A: Any ultrasonic humidifier will leave mist if you use tap water. If it emits mist, its going to leave dust.
submitted byBert_Winters - 9 months ago
A: We recommend using distilled water for best results. As another alternative, purified or filtered water will be slightly better than tap water. However, if using tap water, please be mindful that the unit may need to be cleaned more often due to mineral buildup.

Q: it states no filter is needed in description, is this accurate?
submitted by DM - 7 months ago
A: There is a water filter sponge located in the tank of the humidifier. This installed filter is optional and helps catch minerals from hard water. Please note that as substances in the water oxidize, it is normal to observe some discoloration.
The filter can last up to a month, depending on the quality of the water and the frequency of use. You can soak the filter in distilled white vinegar and then rinse it under warm water to clean it, or you can opt to leave it out altogether.

Q: How do you clean it?
submitted by R - 8 months ago
A: Kindly refer to the back of your manual for detailed cleaning instructions! As a suggested alternative to distilled white vinegar, you may also use:
3% hydrogen peroxide, diluted with water (1:1 ratio)
1 teaspoon of liquid chlorine bleach to 1 gallon of water
For your convenience, we have listed the deep cleaning / descaling / disinfecting process below:
1. Fill the tank with 3 US cups / 710 mL of distilled white vinegar or alternative cleaning solution.
2. Replace the tank cover and swish the solution around the tank.
3. Place the tank on the base and soak for 15–20 minutes. The solution will drain into the base chamber and loosen scale (mineral buildup) in the tank and in the base chamber (including the transducer and float).
4. Carefully dump the solution from the tank and base, ensuring liquid does not flow into the air outlet.
5. If needed, use a soft cloth, the included cleaning brush, or a dish brush to remove scale from all parts
6. Thoroughly rinse all components of the humidifier (carefully avoiding the air outlet and power cord).
7. Pat base and tank dry, and allow to air dry for a day or two.
We hope this helps!

Q: Is this product meant to sit on the floor or can it be put on a nightstand?
submitted by E F - 9 months ago
A: The OasisMist 450S can be placed on a nightstand or a similar elevated surface. It's designed to be versatile and works well in various locations, as long as it's on a stable, flat surface. Ensure there's sufficient clearance around it to allow for proper airflow and mist distribution. Avoid placing it directly on the floor, especially if the floor is carpeted, as this could affect its performance.

Cannot control the humidity lever. It sits at 95% on auto and manual mode
1 reply from Etekcity-Cosori-Levoit team - 5 months ago
We appreciate you sharing your experience with us. To fix this issue, please dry the sensor (behind the aroma drawer) with a hairdryer, or put the humidifier in a well-ventilated place for a few days to get it dried. Also, please swivel the nozzle to point away from the built-in humidity sensor. Otherwise, the falling mist may result in higher humidity levels. If the issue persists, please contact our support team directly at support@levoit.com. We are here to help!

These products are truly disappointing; they caused more damage than benefit. Mist settles everywhere, even inside office printers and other equipment. White dust accumulates especially on furniture, chairs, printers, computers, phones, phone lines—basically everything you can think of. It’s incredibly frustrating. I had to clean all the printers, equipment, and furniture, and ended up injuring my leg in the process. I really don’t understand why manufacturers continue to make products like this.

Thank you for sharing your feedback, John. Depending on the water quality and frequency of use, it is normal to see some "white dust" output, as this is typical for most ultrasonic humidifiers. To help reduce white dust, we recommend regular cleaning as detailed in the manual and using distilled water for best results. As another alternative, purified or filtered water will be slightly better than tap water. We would like to hear more details about your experience so we can better assist you. Please email our support team at support@levoit.com. We are here to help!

please save your money
I purchased this humidifier back in November amd absolutely loved it for the first 3 months.. I have kept up with the maintenance, also descaling and cleaning it weekly. it worked like a dream. however, it started leaking at the base. I was laying down last night and heard a dripping sound next to my bed and sure enough there was a puddle under my humidifier. it was at the base and quickly created a mess in a matter of minutes. right next to the power strip none the less. this was my first Levoit purchase and unfortunately will probably be the last due to how severe the outcome of the leak could have been if I were actually asleep and did not hear the dripping.

Helps with congestion!
I bought this for my 3 year old who is battling an awful cold with heavy congestion. My son had a way better sleep after the first use (used the cold mist). I love that there is a side compartment to add essential oils and the app is a great way to schedule on/off hours.

Love it
I love this humidifier so far. the first one I bought had mold and looked used, so I returned it. When I asked the employee for another they said they were out, but I found them in the store anyway🙄. It works great so far. I was debating the Bluetooth option at first but its a game changer, especially if you have a little one at home. You can control everything on the app even turning it on and off, plus the light options are really cool. Cleaning it and filling it are super easy. Also the modern look of it looks great in a room compared to others in the market.

This is a great humidifier
Over the years, this is by far the best humidifier that I’ve had, and I’ve gone through a lot of humidifiers from many different companies. Everything worked right out of a box no problems connecting through Bluetooth to my phone. I love the fact that you could set the humidity and just leave it. I would highly recommend this one, especially if you get a lot of sinus infections, and if you have allergies. I live in New England and this winter has been really bad and I fill the tank up and it runs all night and only uses about a half of tank. The thing that I love most about it really is that it’s so easy to clean unlike a lot of the other machines that I’ve had would give six stars if I could

Unit leaks
I tried to write a question/comment on this unit and the website wouldn’t accept it. Here is my concern… Our unit leaked all over after the first night. It was leaking down the side of the unit, even though it was turned off. I purchased 2 units, one for each child’s room, but I don’t want this to happen again and possibly cause an electrical fire/electrocution. I had asked if this was a common issue but wasn’t able to post the question so wasn’t able to troubleshoot. I don’t think it’s worth the risk.l in my opinion.

Leaks within two months
We LOVED it until one of the humidifiers leaked during the night. It's a problem with the humidifier (not user error) since it leaks from two areas in the bottom of the base. The pool of water ruined our dresser, which is the biggest problem. Most things are made cheaply now, but I wish I listened to the other reviews and saved my furniture by paying more for a more durable product.
