Care information

  • Before cleaning: Turn the CD600 off, unplug it, and allow the unit to cool before removing the tank or wick filter. Keep water away from the controls and electrical connections.
  • Water and tank care: Empty and rinse the tank regularly. If the humidifier will not be used, empty the remaining water and allow the tank and accessible surfaces to dry.
  • Filter Dry: After use, run the 60-minute Filter Dry cycle to help dry the evaporative wick between uses and reduce lingering dampness.
  • Electrolysis Self-Clean: Add at least 2 L of clean tap water and run the 30-minute self-clean cycle. Discard the water and rinse the wick afterward.
  • Wick filter care: Inspect the rayon/PET evaporative filter regularly. Replace it when it is worn, develops a persistent odor, or output drops despite a full tank. Use a compatible CD600 replacement filter.
  • TrueRoom Sensor: Place the separate humidity sensor in the room area you want to measure, away from direct airflow, heat, sunlight, and splashing. Do not submerge the sensor.
  • Cleaning products: Use clean water and only the cleaning method described in the CD600 instructions. Do not use corrosive chemicals, abrasive materials, or solvents on the tank, wick, sensor, or housing.
  • Humidity setting: Use Auto Mode with a comfortable target humidity and monitor the room so surfaces do not become damp. Keep the surrounding area clear of water-sensitive materials.

Description

CD600 Smart Evaporative Humidifier — Mist-Free, No White Dust

The Powerscale CD600 is a smart evaporative humidifier designed to add moisture to indoor air without producing visible mist or white dust. Unlike ultrasonic humidifiers, evaporative technology draws dry air through a wet filter and releases naturally humidified air without dispersing mineral residue into the room.

The included TrueRoom Sensor measures humidity from a separate location in the room and sends the current reading to the humidifier, helping the CD600 adjust its operation according to the humidity where you actually place the sensor.

Key Features

SEPARATE TRUEROOM SENSOR—MEASURE HUMIDITY WHERE IT MATTERS: Place the factory-paired sensor near your bed, desk or living area. Unlike humidifier-side sensing, Auto Mode can respond to conditions where you actually spend time.

HIGH-OUTPUT HUMIDITY FOR LARGE ROOMS: Delivers up to 700 mL/h and covers up to 700 sq ft. The 6L top-fill tank means more time between refills for bedrooms, living areas and other larger spaces.

MIST-FREE EVAPORATIVE HUMIDIFICATION: Air passes through a water-saturated wick to add invisible moisture without a visible plume. Unlike ultrasonic humidifiers, the CD600 does not create a mineral mist, helping reduce residue on nearby surfaces.

ELEVATED WICK—DRIER BETWEEN USES: The wick remains physically lifted clear of the reservoir instead of sitting in stored water. After use, run the 60-minute Filter Dry cycle to help dry the wick and reduce prolonged dampness.

ELECTROLYSIS SELF-CLEAN CYCLE: Add at least 2 L of clean tap water and start the 30-minute cycle. Electrolyzed water circulates through the internal waterway and wick to support routine cleaning. Discard the water and rinse the wick afterward.

QUIET SLEEP MODE & SMART CONTROL: Operates as low as 25 dB(A) in Sleep Mode for nighttime use. Choose Auto, Normal or Turbo, set 30%–80% target humidity, and manage timers or schedules from the touchscreen or SmartLife app.

1-YEAR LIMITED WARRANTY & REPLACEMENT FILTERS: The CD600 is backed by a 1-year limited warranty and Powerscale customer support for setup, operation and troubleshooting. Replacement wick filters are available separately for ongoing care.

Why Choose Evaporative Humidification?

No white dust
Evaporative humidifiers do not disperse dissolved minerals into the air as visible white residue.

No visible mist
Moisture is released through natural evaporation, helping avoid wet surfaces around the humidifier.

Humidity-based automatic control
The CD600 uses readings from the external TrueRoom Sensor to adjust operation according to the selected target humidity.

No mineral-filled aerosol
Evaporative humidification does not create the fine mineral-containing droplets commonly associated with ultrasonic mist.

Great Features and Convenient Humidity Control

jc1384 · United States

Amazon Vine — Free product provided for review

I received this humidifier through Amazon Vine and really like the features it offers. The 6-liter tank is a nice size, especially for larger rooms, and the top-fill design makes adding water much easier than dealing with a tank that needs to be flipped upside down.

One feature that really stands out is the separate humidity sensor. I like the idea of measuring humidity away from the unit itself, which should give a better picture of the conditions throughout the room. The automatic humidity control is also convenient because you don't have to constantly adjust the settings yourself.

The Wi-Fi connectivity is another nice touch, allowing you to manage the humidifier without having to walk over to it every time. I also appreciate the evaporative design, which avoids the visible mist associated with ultrasonic humidifiers.

Overall, this is a well-equipped humidifier with some thoughtful features. The large tank, external humidity sensor, and smart controls make it an attractive option for keeping indoor air comfortable, particularly during the colder months when the heat tends to dry everything out.

Sensor by my desk during the day, bedside at night

Renée · United States

I use this in my apartment and keep the humidifier near my sofa. During the day, I place the separate sensor near my desk, and at night, I move it to my bedside table. I like that I can only moving the small sensor instead of moving the whole humidifier.

I selected Auto Mode directly on the humidifier without installing the app. I honestly do not like installing new apps on my phone lol. I set the targeted humidity to 55% on the touchscreen. The sensor stayed connected in both locations, about 10 feet and 25 feet from the humidifier. The longest distance I tested between the sensor and the humidifier is around 40 feet and I’m glad that it still worked! I like that Auto Mode responds to the humidity where I’ve placed the sensor, whether I’m studying or sleeping.

Perfect for large, open concept room

XMICHIGO · United States

Great humidifier for open spaces! We placed this humidifier in our chill-out area, which flows right into a large seating space.

And I was able to place the humidity sensor all the way across the living room on my kitchen island while keeping the humidifier base tucked away (about 30 feet away). I set it at 60% in Auto Mode and it adjusts the moisture perfectly.

It features a large water tank and user-friendly maintenance options. Unlike my old humidifier, this one leaves absolutely no wet mist or chalky residue on my electronics.

Cool features, no fog

Jessica Leigh · United States

Actually very impressed with this humidifier as it does not fog the room up and works like an extra little cooler too. It keeps moisture in my daughters room without being too excessive or foggy. Easy to refill and has a cool app you can download to control from you phone with child lock settings--which if you have a toddler is super helpful!

Great humidifier option

Optimus Prime · United States

Amazon Vine — Free product provided for review

We live in an older house and often have issues with temperature and humidity control. Not only that but this has been incredibly useful when someone in the household is sick to control coughing and a sore throat, especially at night. When it comes to usage luckily the instructions are very clear and easy to understand. It's makes it easy to get the machine up and running. The machine puts out quite a bit of moisture without any real visible misting. I also like that the room doesn't feel excessively damp, and there's no clear wet or moist spots around the humidifier. It is also very quiet so can be used in a room without disrupting conversation. I haven't had to take anything apart yet luckily for cleaning since it has an auto cleaning cycle. Overall this is an expensive machine. But I think at $199 it is a good value for the money, especially for those with dry homes or who wake up with scratchy throats or constant coughing.

Smart and Powerful Humidifier for Large Rooms

costco · United States

Amazon Vine — Free product provided for review

This Powerscale humidifier is a great option for adding moisture to larger rooms and living spaces. The 6-liter top-fill tank is convenient to refill, while the 700 mL/h output provides plenty of humidifying power for spaces up to 700 square feet. I like the separate humidity sensor because it allows for more precise monitoring of the room’s moisture level. The Wi-Fi app control is also convenient for adjusting settings without having to walk over to the unit. Features like the 60-minute filter dry cycle and electrolysis self-cleaning make routine maintenance easier as well. Overall, it’s a feature-packed humidifier with plenty of capacity and smart controls for everyday use.

No mist, just moisture

Unik · United States

Amazon Vine — Free product provided for review

This humidifier comes as one piece, but it breaks down into four main parts. The larger outer piece is the top cover, which is what you see in the product photos, and it sits over the water tank inside. You need to make sure you support the bottom when moving the unit because the tank is not snapped to the cover. Nothing actually locks the top cover and tank together.

Inside the cover is the bottom tank, which is made of two pieces, and the blue filter sits in the middle. The filter needs to be cleaned every 2 to 4 weeks using the self-cleaning mode. The filter only lasts around 3 to 6 months, with replacement every 3 months being most ideal. The filter is double-wall lined on the inside and outside.

The instructions are thorough and very helpful, with clear demonstration illustrations. You can connect the unit to a phone app through Wi-Fi and control it from your phone, since there is no remote included.

You can fill the tank from the outside while the cover is still on. You would only need to take the unit apart initially to access the room-temperature sensor inside. The tank holds up to 1.8 gallons of water. Purified water is recommended instead of tap water. There is a water-level indicator on the screen, so you can see how much water is left without having to access the water tank at the bottom. It is not recommended to use essential oils in this humidifier.

The room-temperature sensor is a separate device that connects with the humidifier by Bluetooth. The unit responds to that reading, so it is best to keep the temperature sensor in the same room as the humidifier. It uses three AAA batteries, which are included.

The cord is USB-C. The unit is about 18½ inches tall and 9½ inches wide. It is medium weight and does not feel like cheap lightweight plastic. It can cover up to around 700 square feet.

Overall, this is a major upgrade from using an oil diffuser that claims it can double as a humidifier. Although you can’t use essential pils with this device you won’t get that wet mist since this machine does not produce one. Because there is no mist, I can run my air purifier at the same time. It adds moisture without making your room feel damp or leaving water residue around your space.

The machine is not completely silent, but the noise level is similar to my Alen air purifier on low. If you live in an apartment or use central air, which can be extremely drying, this is a must. I do not wake up with a sore throat like I did with smaller devices that released too much wetness on my nightstand and made me sick in the winter.

Works fine

Amazon Customer · United States

Amazon Vine — Free product provided for review

I have been using this humidifier for a while now; it features a large water tank, and the top-fill design makes adding water incredibly convenient. It operates quietly and effectively maintains a comfortable indoor environment, especially when the air is dry. Thanks to the Wi-Fi-enabled mobile app, I can check humidity levels and adjust settings at any time without having to get up. The filter drying and automatic cleaning functions are also very practical; however, the app's user experience leaves room for improvement, and the unit itself is somewhat bulky compared to standard humidifiers.

Feature-Packed Humidifier That’s Designed for Larger Rooms

J&E · United States

Amazon Vine — Free product provided for review

This Powerscale humidifier feels like a significant step up from the small tabletop models I’ve used before. The 6-liter top-fill tank holds plenty of water, and the 700 mL/h output gives it enough capacity for a bedroom, living room, or other larger space without needing constant refills. The separate humidity sensor is one of the features I appreciate most. Instead of measuring humidity only right next to the machine, the sensor can give a better idea of the conditions elsewhere in the room. The Wi-Fi app control is also genuinely convenient for checking or adjusting the humidifier without walking over to it. I also like the thought that went into maintenance. The elevated wick, electrolysis self-cleaning function, and 60-minute filter-dry cycle address some of the less enjoyable parts of owning a humidifier. Anything that helps keep the inside cleaner and prevents the filter from simply sitting wet after use is a welcome addition. For someone who wants more than a basic on/off humidifier, this has an impressive combination of capacity, output, smart controls, and maintenance features. It feels designed for regular use rather than something you’ll get tired of constantly refilling and cleaning. Five stars.

Lots of Useful Features but the Price Is Pretty High

Johnny N. · United States

Amazon Vine — Free product provided for review

This humidifier has a lot going for it if you want something more advanced than the basic fill it and forget it models. The large tank, top fill design, app controls, quiet sleep mode, and separate humidity sensor all make it easier to use in a larger room. The filter drying and cleaning functions are also nice because humidifiers can get gross surprisingly fast if they stay wet all the time.

The main downside is the price, especially when you also have to think about replacement filters later. The separate sensor is a good idea, but it may need to stay closer to the humidifier than expected to keep a reliable connection. Overall, it is a very capable humidifier with some thoughtful features, but at this price it feels like it should almost refill itself too.

The Ultimate Whole-House Humidifier – Intelligent Sensing and Zero White Dust!

Gorr · United States

Amazon Vine — Free product provided for review

The Powerscale CD600 Evaporative Humidifier is a masterclass in smart home climate control. If you are tired of humidifiers that only measure the air right next to the machine, or ultrasonic models that coat your furniture in white mineral dust, this advanced unit is the perfect upgrade for larger spaces. Features a factory-paired remote sensor you can place exactly where you sit or sleep. Auto Mode adjusts based on the humidity where you actually spend time, not just right next to the tank. Pumps out up to 700 mL/h of moisture, easily covering up to 700 sq ft. The extra-large 6L top-fill tank cuts down on refills, making it perfect for sprawling living areas or master bedrooms. Uses a water-saturated wick to release invisible, natural moisture. Because it isn't ultrasonic, it creates zero mineral mist, completely protecting your furniture and electronics from white residue. The wick sits physically lifted above the water reservoir when not in use. A built-in 60-minute Filter Dry cycle quickly bakes out prolonged dampness to keep the system pristine. Features a 30-minute self-cleaning cycle that uses electrolyzed tap water to flush the internal waterways and wick, taking the headache out of routine maintenance. Operates at a near-silent 25 dB(A) in Sleep Mode. You can easily adjust target humidity (30%–80%) or set automated schedules via the touchscreen or the SmartLife app. It is an incredibly well-thought-out, high-capacity humidifier that delivers clean, smart, and hassle-free moisture exactly where you need it.

Easy to use and packed with useful features

Rickydelivers · United States

I have used a few humidifiers over the years, and this one feels much more thought out than the basic models I am used to. The 6 liter tank is a really nice size, and I especially like the top fill design because I can add water without having to flip over a heavy tank and make a mess. The separate humidity sensor is another feature I appreciate because I can place it across the room and get a better idea of the actual humidity instead of only measuring right next to the machine. The app is easy to use and makes it convenient to adjust the settings without getting up. I also really like the filter drying and self cleaning features because humidifiers can get gross quickly if they stay damp all the time. It runs quietly, puts out plenty of moisture for a larger room, and so far has been easy to maintain. This is one of the more convenient and user friendly humidifiers I have used.

The best humidifier I have owned

Faith S. · United States

Amazon Vine — Free product provided for review

With winter approaching, I wanted to share my thoughts on the new smart humidifier I recently purchased. It has greatly simplified things and will definitely improve our indoor air quality this season.

A few key features that make it stand out include:

- Smart Controls: It features a built-in humidity sensor and allows you to set a specific target humidity level. - Safety & Maintenance: The unit automatically shuts off when empty and includes a filter-drying setting for use after cleaning. - User-Friendly: It is easy to fill, and the included instructions are very straightforward to follow.

I highly recommend it if you are looking for a reliable humidifier for the winter.

Really nice humidifier, works great

Amazon Customer · United States

Amazon Vine — Free product provided for review

I like how much control this Powerscale CD600 gives me compared with the simpler humidifiers I have used, and I find the 6 liter top fill tank particularly convenient because I can add water without carrying the entire unit to a sink. I appreciate the separate humidity sensor because I can position it away from the humidifier and get information from another part of my room instead of relying entirely on a sensor sitting beside the moisture source. I find the evaporative design appealing because I do not see a visible plume of mist settling around nearby surfaces, while the rated 700 mL per hour output gives me plenty of capacity for my larger living spaces. I especially like the WiFi app control because I can check settings and make adjustments from my phone without walking over to the unit every time. The elevated wick design is thoughtful, and I appreciate having the 60 minute filter drying function after operation because it gives me a dedicated way to dry the filter rather than simply leaving everything damp inside the unit. I also like having the electrolysis self cleaning feature as part of the maintenance routine, although I still perform the regular cleaning and filter care recommended for the humidifier rather than treating it as completely maintenance free. The controls are easy for me to understand, the tank opening provides convenient access for refilling, and the overall design looks clean enough that I do not mind keeping it visible in my living area. Overall, I am pleased with the large 6 liter capacity, strong evaporative output, remote humidity sensing, convenient top filling, app controls, filter drying function, and thoughtful maintenance features, and I find the CD600 particularly well suited to my larger rooms.

Smart Humidifier with Lots of Convenient Features

Rose ♥ · United States

Amazon Vine — Free product provided for review

This is a really nice humidifier if you want something a little more advanced than a basic unit. The 6L tank is a great size for everyday use, and I really like the top-fill design because it makes refilling much easier. Not having to wrestle with an awkward tank is a small thing that makes a big difference when you're using a humidifier regularly.

The separate humidity sensor is another feature I really like because it gives the unit a better way to monitor the humidity in the room rather than simply running without any feedback. The Wi-Fi app control is also convenient, especially if you want to check or adjust the humidifier without getting up to do it manually.

I also appreciate the features aimed at keeping the unit maintained. The filter-dry cycle and self-cleaning function are nice additions because humidifiers require regular upkeep, and anything that makes that process easier is a win in my book.

With coverage advertised for up to 700 square feet, this is a good option for a bedroom, living area, office, or other larger room where you want to maintain a more comfortable humidity level.

Overall: A feature-packed humidifier with a large 6L tank, convenient top-fill design, humidity sensor, app control, and helpful maintenance features. It's a great option if you want more control and convenience than you'd get from a basic humidifier.

Very user friendly, Efficient, easy to clean

hstrick · United States

Amazon Vine — Free product provided for review

First things first, when looking for a humidifier, I always look for one that is easily cleaned. When you have constant moisture, mold and mildew tend to be an issue. This humidifier is extremely easy to clean, take apart and dry out. They sacrifice a bit of ease of use to make this so, but it is worth it. You have to carry this from the bottom as it slides on and off with no latch or securable device. that being said, all the large pices are removable, and the smaller piece they have addressed by their self clean function and their dry out function. Both are super AWESOME, and really shows they put some thought in developing this. The humidity sensor is nice, but it is only battery powered, which just makes one more item in my house that I need batteries for. Alas, if you want modularity, it has to be battery powered. The app is pretty easy to use, the controls are easy to use, and pretty much everything with this is easy to use. Funny enough, they use a usb C power plug, which is quite convenient. All in all, super ease of use, good quality product with great humidity output without being super obnoxious. well priced as well

Good value and quality

Nicky N. · United States

Amazon Vine — Free product provided for review

I’ve been running this 6L evaporative humidifier in our open living area for a week now. It’s been working well without any of the white dust or wet-floor mess that old ultrasonic models left behind. The separate humidity sensor actually keeps the room right at my set level. It easily handles our 700 sq ft space, even with the heat on. I’m love the top-fill tank feature so I can just carry it straight from the sink, no flipping or spilling. The elevated wick design seems to make evaporation faster and more efficient. The 60-minute filter dry cycle is a lifesaver because it stops musty smells before they start. The self-cleaning electrolysis feature gives me real peace of mind that I’m not misting bacteria into the air. Wi-Fi app control means I can tweak settings from the couch or turn it on before I get home, which feels ridiculously convenient. It’s quiet, and easy to maintain. This is a nice investment for the long term.
