10 Best Air Purifier 2025 in the UK

The LEVOIT Air Purifier Core Mini is a compact and efficient option, particularly well-suited for small spaces like bedrooms or office desks. It boasts a 3-layer HEPA filter that effectively removes a broad range of pollutants, including dust, pet dander, and odors. This feature makes it ideal for allergy sufferers or anyone looking to maintain a cleaner air environment. The purifier covers an area of 34 square meters with its advanced VortexAir 3.0 technology, although it's worth noting that larger rooms might require a more robust model.

A standout aspect is its energy efficiency; at 7 watts, it is Energy Star certified and offers minimal energy consumption, costing approximately 28 pence for a week of continuous use. This is a significant advantage for those mindful of energy bills. Its quiet operation at 25 dB makes it a great choice for nighttime use, ensuring it won’t disturb your sleep.

One unique feature is the built-in aromatherapy option, allowing the use of essential oils to create a pleasant atmosphere in your space. However, this may not appeal to everyone, especially those sensitive to scents. The unit is also designed to be ozone-free, avoiding the production of harmful ozone which is a plus for those health-conscious about air purification.

On the downside, the purifier's coverage may not be sufficient for those seeking to purify larger living areas, and reliance on official Levoit filters might be seen as a drawback due to ongoing replacement costs. Nonetheless, it's user-friendly with simple controls and an indicator for filter replacement, making it easy to maintain and operate. This purifier provides a balanced mix of air cleaning effectiveness, energy efficiency, and added features suitable for smaller spaces.

The Blueair Blue 3610 Air Purifier is a solid choice for medium to large rooms, covering areas between 51m² and 122m². It utilizes HEPASilent technology, combining mechanical and electrostatic filtration to remove a high percentage of airborne pollutants, including pollen, dust, mould, bacteria, and viruses. Its activated carbon filter effectively reduces odors and VOCs, making it suitable for households with pets, smokers, or frequent cooking activities.

One key strength is its ultra-quiet operation at just 23 dB on low fan speed, making it ideal for bedrooms or other quiet spaces. Additionally, the auto mode function adjusts fan speed based on real-time air quality, adding to its user-friendly design. The unit is energy-efficient, consuming only 4W-38W of power, which is less than a typical lightbulb. The washable pre-filter is a practical feature that can help extend the life of the main filter.

However, it's worth noting that the noise level can reach up to 56 dB at higher settings, which might be noticeable in quieter environments. The 3610's straightforward design, with a single-button control and a three-color air quality indicator, simplifies operation but might lack the advanced connectivity features found in some other models. For those seeking an effective, easy-to-use air purifier that excels in quiet performance and allergen removal, the Blueair Blue 3610 is a commendable option.

The LEVOIT Smart Wifi Air Purifier, particularly the Core 300S model, is a strong contender for those looking to improve the air quality in medium to large spaces, such as bedrooms and living rooms, up to 100 square meters. With a CADR of 240 m³/h, it is efficient in circulating and cleaning air, which can be particularly useful for allergy sufferers looking to remove pollen, dust, and pet dander from the environment. The inclusion of a three-stage filtration system—comprising a pre-filter, H13 HEPA filter, and activated carbon filter—enhances its ability to clear airborne particles and odors effectively.

One of its standout features is the real-time air quality monitoring, aided by a laser dust sensor, which can provide users with precise air quality feedback via the smart VeSync app. This function, along with Alexa and Google Assistant compatibility, adds a layer of convenience, making it easy to manage settings hands-free or adjust them remotely. The Core 300S offers a quiet operation, particularly in sleep mode where it operates at just 22 dB, ensuring it doesn’t disturb light sleepers. Energy efficiency is another plus, as it operates with a DC motor that keeps consumption low, even at higher speeds.

For some, the need to replace filters every 6-8 months could be seen as a downside, potentially adding up to the running costs over time, although this is quite common for air purifiers. While it’s equipped to handle larger rooms, its most effective operation is for spaces up to 50 m² when considering two complete air exchanges per hour. This might require users with larger areas to run the purifier for longer periods to maintain optimal air quality.
