The best ionizer-humidifiers and air purifiers

Ionizers, humidifiers, and air purifiers are devices used to improve the quality of the air we breathe, but they work in different ways. In this article, we’ve rounded up the best ionizers, air purifiers, and humidifiers of the year. Let’s start by looking at how they differ:

  • Ionizers are devices that produce negative or positive ions and release them into the air. These ions interact with dust and allergen particles, making them heavier and easier to remove from the air or causing them to settle on surfaces.
  • Air purifiers remove pollutants from the air using filters. These filters can trap particles such as dust, pollen, allergens, and germs, thereby improving the quality of the air we breathe.
  •  Humidifiers are devices that increase the humidity in the air by releasing water or steam. They are used to humidify the air in dry environments or during winter, when heating can make the air dry.

In short, ionizers release ions, humidifiers increase humidity, and air purifiers remove pollutants using filters.

A user review we singled out

"I'm a smoker. It creates a pleasant atmosphere. It also produces a pleasant white noise—just right for sleeping. Even my cat goes and lounges next to it on the sofa, despite being afraid of noises (e.g. the vacuum cleaner)."

Featured user review

"So, this little thing is simply perfect. I have a room where I game, stream and generally spend hours smoking, gaming and eating. Ever since I got it, the whole atmosphere in the room has changed. It takes care of cigarette smoke, dust, everything, and the filter—what can I say? Twist, remove, insert, twist: changing it couldn’t be easier. In Auto mode, it detects things automatically, but I mainly turn it on with Google Home at maximum, where it does its best work. If you have a large room, you’ll appreciate this feature. TOP machine, both for its price and how easy it is to use."

"Great value for money, with Wi-Fi, a good size, and an app.
Very quiet; you can only hear the water moving and the motor very faintly if it’s close to you.

I really like its blue light. You can turn it off.

I say the same about other Xiaomi products: it’s a good buy for the price. If you don’t want the cheapest option, but don’t want the most expensive either, it’s a solid and effective baseline product."
