The Bottom Line

Levoit is a giant in the industry, and the 300S is excellent if you need smart home integration. However, for personal use or smaller rooms, it feels a bit oversized and the price point is higher than necessary for basic needs.

  • NanoCloud evaporative technology (no white dust)
  • Spreads 99% less bacteria

The Bottom Line

Philips offers a robust machine that uses evaporative tech rather than ultrasonic mist. While hygienic, the high upfront cost and the need to constantly buy replacement filters make it a costly investment compared to the maintenance-free Clairu.

  • Boils water to kill bacteria
  • Compatible with VapoPad for scent
  • Warm mist is soothing for congestion

The Bottom Line

A classic choice for when you have a cold, but not great for everyday use. The energy consumption is high, and the boiling water mechanism presents a safety hazard for children and pets that ultrasonic models avoid.

How Clairu Humidifier Earned Our Confidence

Clairu Humidifier real-world testing

1. Clairu Humidifier

Price: £59.99

The Clairu Humidifier uses ultrasonic technology to deliver a whisper-quiet mist that won’t disturb your sleep or work. Its compact and portable design fits easily on desks, bedside tables, or shelves, so you can place it almost anywhere. Adjustable mist levels let you choose between low and high output to suit your room size and humidity needs, giving you full control. The device features built-in LED mood lighting with multiple colours, creating a relaxing atmosphere.

Powered by USB, it connects to laptops, power banks, or standard adapters, making it highly portable. The water tank is easy to fill and clean, and the auto-shutoff feature ensures safety by turning the device off when water runs out, giving you peace of mind. Overall, the Clairu is an excellent choice for anyone seeking an effective and versatile humidifier without spending a fortune.

2. Levoit Classic 300S Smart Humidifier

Price: £69.99 | Score: 8.8

This smart humidifier offers app control and voice assistant compatibility, ideal for tech-savvy users who want to manage their home environment from their phone. It delivers consistent mist output and features a larger tank capacity suitable for bigger rooms, meaning less frequent refilling. However, it is slightly noisier and more expensive than the Clairu.

3. Philips Series 2000 Air Humidifier

Price: £129.99 | Score: 8.2

The Philips Series 2000 provides warm mist humidification with advanced air quality sensors. This means it not only humidifies but also helps you monitor your air quality. It is highly effective but comes with a premium price and a bulkier design. It’s ideal for users who want both air purification and humidity control, offering dual benefits.

4. Vicks Warm Mist Humidifier

Price: £44.99 | Score: 7.6

A budget-friendly warm mist option that helps relieve cold symptoms, making it a great choice when you’re feeling under the weather. It is simple to use but lacks advanced features and runs louder than ultrasonic models, so it might not be ideal for quiet spaces.

5. Russell Hobbs 2-in-1 Humidifier

Price: £34.99 | Score: 7.1

This unit combines humidifier and diffuser functions in a compact design, so you get two benefits in one small device. While affordable, its performance and mist output are limited compared to higher-end options, making it best for smaller spaces or occasional use.

Humidifier Buying Mistakes That Cost You More

Clean your humidifier regularly to prevent mould and bacteria.

Imagine breathing air filled with invisible nasties. To avoid this, clean your humidifier at least once a week. This simple step stops mould and bacteria from building up inside, ensuring the mist you breathe is clean and healthy.

Use distilled or filtered water to reduce mineral deposits.

Have you noticed white dust settling around your humidifier? That’s from tap water minerals. Using distilled or filtered water reduces these deposits and prevents ‘white dust,’ which means your humidifier works better and lasts longer.

Avoid over-humidifying rooms to prevent mould growth.

While dry air is uncomfortable, too much moisture can cause problems like mould growth and dust mites. Keep your home’s humidity between 30-50% to stay comfortable and healthy, so you find the right balance.

❓ Frequently Asked Questions

How often should I clean my humidifier? +
Clean your humidifier at least once a week to prevent bacteria and mould growth, ensuring the air you breathe stays fresh. Some models may need more frequent cleaning depending on usage.
Can I use tap water in my humidifier? +
You can use tap water, but it often causes mineral buildup and ‘white dust’ around your home. Using distilled or filtered water improves performance and extends your humidifier’s life, meaning less cleaning and a healthier environment.
Is ultrasonic technology better than warm mist? +
Ultrasonic humidifiers are generally quieter and use less energy, making them great for bedrooms. Warm mist models can reduce bacteria and may feel more comforting during cold seasons. Choose based on your personal preference and health needs.
Will a humidifier help with dry skin and sinuses? +
Yes! Humidifiers add needed moisture to the air, which can significantly relieve dry skin and irritated nasal passages. This means you’ll feel more comfortable, especially in heated indoor environments that tend to dry you out.
