About this product
The Vicks VH845 Warm Mist Humidifier helps you breathe easier and sleep better by releasing up to 99% bacteria-free warm mist into the air. Designed for rooms up to 37 square meters, it creates a more comfortable environment with a large water tank that provides hours of soothing moisture. You can choose between two mist output settings - high for when you need extra humidity or low for gentle, consistent comfort. The visible water level lets you see exactly when it needs refilling, and the auto shut-off kicks in when the tank empties, giving you peace of mind.
It fits neatly on a bedside table or dresser without taking up too much space. The variable speed control means you're always in charge of your comfort level, whilst the warm mist technology helps tackle dry air that can affect breathing and sleep quality. It's compatible with VapoPads (two included) for added soothing vapours when you need them. The long cord gives you flexibility with placement, and with quiet operation, it runs without disrupting your rest. Backed by a 2-year manufacturer's guarantee, it's reliable moisture control that's there when you need it most.

A great help.
I bought this while suffering the after effects of pneumonia, it was hanging on, my chest felt congested my nose blocked, after 3days of running this day and night my chest was a lot clearer. I dropped down to night time use only, it certainly helped get a restful night. The warm vapour soothes the Airways, it is quiet so doesn't disturb you.Easy to use and clean. Highly recommended. JUST USE PLAIN WATER IF YOU HAVE CATS OR DOGS.

Toddler essential
We brought this to help woth my toddlers nighttime cough and our own nursery germs... and it really did help us all! Would absolutely reccomend this product and used it with the pods and without. Just make sure you move it away from a wall as the water vapour will sit on your walls, no harm done though!

Great product
I bought this Vicks Warm Mist Humidifier recently and have been happy with it so far. It was easy to set up and started producing warm mist quite quickly. I mainly use it at night and noticed the air in the room feels less dry, especially when dealing with a cough or blocked nose. It runs quietly enough that it doesn’t disturb sleep, and the tank size lasts a decent amount of time before needing a refill. Cleaning is fairly straightforward too. The only small downside is that it takes up a bit more space than I expected, but overall it does the job well and feels like a useful addition during colder months.

Helps a congested person breath and sleep.
Definitely produces steam and does help with breathing if you are congested. If anything it produces too much steam compared to their previous warm humidifier! It is quiet and the vapour inserts are subtle (I don't like string smells!) so OK.

Primitive
Doesn't seem to have any feedback: just boils water up the wall until it is dripping wet.

Worst quality
Worst quality of product. Water holding tank got cracked during working/operating on the second day of use and started water leaking from the cracks.
Aish, 35 - 44
An average item
The device generates a decent amount of steam. However, I found the small pads to be useless. Even when I inserted two of them into the humidifier, there was no trace of their scent in the air. After using the device just once, I thoroughly cleaned it. To my dismay, I discovered that most of it was covered in a brownish buildup. Unfortunately, I'm unable to include photos with this review.

Hello and thank you for your question! One of the great features of the Vicks VH845 Warm Mist Humidifier is that it is filter-free, so you won't need to worry about the cost or hassle of regular filter changes. Because it boils the water to produce steam, it simply requires regular cleaning (descaling) to remove mineral buildup, especially if you live in a hard water area.

Hello Maz, thank you for your question. Generally, the Vicks VH845 Warm Mist Humidifier is safe to use in a room with a pet, provided it is placed on a stable, elevated surface out of the dog's reach to prevent any risk of tipping or contact with the warm steam. However, because Chihuahuas have sensitive respiratory systems, we recommend using only plain water and avoiding the use of VapoPads or essential oils. If you have further concerns, your local veterinarian is always the best resource for advice tailored to your pet's health.

Hello and thank you for your interest in our product! The Vicks VH845 Warm Mist Humidifier can absolutely be used on its own to provide soothing warm mist without VapoPads. The VapoPads are an optional accessory that can be added if you’d like a menthol or other scented vapour, but they are not required for the humidifier to function. Many people choose to run the unit with plain water only, especially when looking for simple moisture relief from congestion. Later on, when desired, the VapoPads can be used to add extra comfort for coughs and colds. If any additional information is required, please do not hesitate to approach us at Vicks_WICK_Support@helenoftroy.eu
We wish you and your wife comfort and wellbeing during this special time.

Hello Elron, thank you for your question. We believe you may have meant to ask whether the Vicks VH845 produces a visible mist rather than “most.” Yes, the VH845 Warm Mist Humidifier does release a clearly visible warm mist when operating. This mist helps to add moisture to the air, supporting comfort during dry seasons and easing symptoms such as congestion or dryness. The mist is safe, soothing, and you’ll notice it rising from the unit during use. Regular cleaning and maintenance will ensure the mist remains fresh and effective.

Thanks for using Q&A.
Hi! Thank you for your question. You can use tap water, but the result may vary due to the region you live in and the local tap water.
We recommend cleaning your humidifier once a week or once a month.
Here are some steps to stop bacteria and scale forming in your humidifier.
Take out the water tank and slowly pour 0.5 litres of undiluted, distilled white vinegar into the reservoir on the water tray.
Pour vinegar over the blue locking latch.
Only pour vinegar into the deep reservoir.
Note: Pour slowly to allow the vinegar to flow from the reservoir into the heating chamber.
Leave for 20 minutes to loosen any scale on the heating element.
Steps for removing scale from the water tank:
Pour in more vinegar, replace the cap and swish to coat the inside.
Wipe away any scale with a damp cloth.
Remove the mist chimney by sliding the blue latch and lifting it towards the front.
Remove the heating element cover by lifting it off the round part.
Open the round opening and pull the cover away from the chimney.
Wet the brush with vinegar from the water tray.
Scrub the surface of the heating element.
Cover the reservoir and heating chamber to remove mineral deposits.
We hope you find this information useful.

You can, and I do, use essential oils with this. You cant put the oils directly in the water tank, but there is a blue inhalant tray over the steam outlet which is specifically for things like essential oils.
Good day,
Thank you for bringing this to our attention. We sincerely apologize for any misunderstandings caused.
The Vicks VH845 Warm Mist Humidifier is specifically designed for use with Vicks VapoPads only. We do not recommend adding essential oils, medications, or inhalant liquids directly into the water tank, as this could damage the humidifier and its components, as well as void the warranty.
However, if you’d like to enjoy the benefits of essential oils, you can use Vicks VapoPads, which are pre-saturated with essential oils. To use, simply open the scent pad door on the humidifier, insert up to two pads, and close the door. Additionally, the device features an Inhalant Cup where you can place essential oils for safe use.
We have attached the user manual below for your reference, which provides further details.
