The Dyson AM10 was the humidifier that put a UV light in the water tank and called it hygiene. People loved the idea. Then Dyson moved on, and the AM10 started disappearing from shelves.
Short answer: if a store still sells you an AM10, check the warranty and parts first. If not, there are better ways to spend the money. Our search found no current Amazon listing for the AM10, so the picks below are products that are actually for sale.

What the AM10 was
The AM10 was an ultrasonic humidifier and fan with a 3-liter tank. Dyson says its Ultraviolet Cleanse technology exposes every drop of water to UV-C light in a 3-minute cycle and kills 99.9 percent of bacteria in the tank. It also had a built-in humidistat and was advertised for rooms of around 400 sq ft.
A UV light cleans bacteria in the tank water. It does nothing about the white mineral dust that ultrasonic units can send into the air, so the water you use still matters.
Is the UV light worth paying for?
A clean tank matters. Dirty humidifiers can send microbes into the air, and the EPA says to empty, dry and refill portable tanks daily. A UV step helps, but it does not replace cleaning. Think of it as a bonus. Distilled water and regular cleaning do more for most homes.
What to buy instead
A simple, long-run humidifier: Pure Enrichment HUME Sense
At $119.99, the HUME Sense is a top-fill humidifier with a 2-gallon tank, warm and cool mist, an auto humidity sensor and a 5-year warranty. It also has an antibacterial tank and a UV light, according to the listing. See our HUME Sense review.
A Dyson combo: Purifier Humidify+Cool PH03
If the Dyson badge is the point, the PH03 combines purifying, humidifying and cooling for $499.99. Amazon shows a 3.3-star rating from 54 buyers, which is lower than many cheaper units, so read recent reviews first. See also our Dyson PH2 review.
| Model | Type | Best for | Price |
|---|---|---|---|
| Pure Enrichment HUME Sense | Top-fill, warm and cool mist | Bedrooms and nurseries | ~$119.99 |
| Dyson PH03 | Purifier, humidifier and fan | Buyers who want one premium unit | ~$499.99 |
Prices checked October 2026 and change often.
Keeping any humidifier clean
- Empty the tank and refill with fresh water daily.
- Clean every third day, following the manual.
- Use distilled water in ultrasonic models to cut mineral dust.
- Keep humidity below 50 percent.

Where humidifiers are heading
Expect UV-C and antimicrobial claims to show up on cheaper models. Some will be useful and some will be marketing. A 99.9 percent claim only means something if the test says what was tested, how long, and in what water.
The other thing to expect is more combination units, and more gaps between a brand’s reputation and its reviews. When a premium unit has a lower rating than a budget one, believe the rating.
Dyson AM10 vs the options today
| Feature | Dyson AM10 (older) | HUME Sense | Dyson PH03 |
|---|---|---|---|
| Humidifies | Yes, ultrasonic | Yes, warm or cool | Yes |
| Purifies air | No | No | Yes (HEPA H13 sealed) |
| Tank | 3 L | 2 gal | See listing |
| UV in tank | Yes | Yes (per listing) | UV cleanse tech varies by model |
| Price | Not for sale on Amazon | $119.99 | $499.99 |
The surprising line is the UV light: the $120 HUME Sense lists one too. The old premium for UV has mostly gone.
If you already own an AM10
- Keep cleaning the tank on schedule. UV does not remove scale.
- Use distilled water to cut mineral dust.
- Ask Dyson support about replacement parts and filters.
- Watch for the humidity target: keep it at or below 50 percent.
What to check when buying any humidifier
- Tank size and how many days it runs.
- Whether it has a humidity sensor so it shuts off on its own.
- Whether the tank opens wide enough to clean by hand.
- Warranty length and parts availability.
- Recent Amazon reviews, not just the star average.
Warm mist, cool mist or evaporative?
Cool mist ultrasonic units are quiet and cheap to run but can leave mineral dust. Evaporative units trap minerals in a wick and are a good fit for hard water. Warm mist boils the water, so it is cleaner at the source but uses more power and adds a burn risk. Our filterless humidifier picks cover the cool-mist side, and the 15 best humidifiers list covers more options.
What happens next: expect more models to add UV or antimicrobial features and to advertise them loudly. Do not be surprised if a few claims fall apart under independent tests.
