10 Best Air Purifiers 2025 in the UK

The LEVOIT Core Mini air purifier is a compact option designed for small spaces, offering effective air cleaning with its 3-layer HEPA filter. It's particularly suitable for bedrooms or home offices due to its quiet operation at 25 dB and energy efficiency, consuming just 7 watts of power. This means low impact on your electricity bill, making it a cost-effective choice for continuous use. Covering up to 34 square meters per hour, it efficiently tackles dust, pet dander, smoke, and odors, making it ideal for users with allergies or sensitivities.

Integrated aromatherapy is a nice bonus, allowing you to add essential oils for a fragrant atmosphere, though this is more of a lifestyle feature than a necessity. The unit is also free from ozone production, which can be a concern with some air purifiers.

However, with its small size and purification capacity, it may not be the best choice for larger living areas. The need to replace filters every 4 to 6 months could be a recurring expense and hassle, though genuine filters are recommended to maintain performance. While it's suitable for personal spaces, those needing more robust air cleaning for larger rooms might need to look at higher-capacity models.

In terms of ease of use, the Core Mini is straightforward with simple button controls and a filter reset indicator. Its compact design, lightweight body, and user-friendly interface make it a convenient choice for those who want straightforward, efficient air purification without fuss.

The Levoit Smart Wifi Air Purifier Core 300S offers a solid solution for rooms up to 100m², making it suitable for larger bedrooms or living spaces. With a CADR of 240m³/h, it efficiently removes common allergens like pollen, dust, and pet dander. Its 3-stage filtration system includes a HEPA filter that is effective for thorough air purification, and the added smart features like Alexa compatibility and a dedicated app provide convenient control options.

For those concerned about noise, the device runs quietly, especially in its sleep mode, at just 22dB. This makes it ideal for use in bedrooms or other quiet environments. Furthermore, the Core 300S is energy-efficient, thanks to its DC motor, which keeps running costs low even with continuous use.

However, frequent filter replacements every 6-8 months could involve additional costs, although the availability of different filter types allows customization based on specific needs, such as pet allergies or toxin absorption. While its smart capabilities are a highlight, they might be less appealing to users who prefer manual control or lack smart home setups.

The air purifier is relatively compact and lightweight, making it easy to place or move around as needed. Despite these strengths, users with significantly larger spaces might find its room coverage insufficient. For its price and features, it remains a good choice for individuals seeking a balance of performance, quiet operation, and modern convenience in air purification.
