10 Best Home Air Purifiers 2025 in the UK

The LEVOIT Air Purifier Core Mini is designed to keep your small spaces like bedrooms and offices fresh and clean. It’s compact and lightweight, making it easy to move around. This purifier is particularly quiet, operating at just 25 decibels, ensuring it won’t disrupt your sleep or work.

Its 3-stage HEPA filtration system effectively tackles common air quality issues such as dust, pet dander, and smoke, covering up to 17 square meters in 30 minutes. You can add a few drops of your favorite essential oils to the aroma pad for a pleasant fragrance while it cleans the air.

Users will appreciate its energy efficiency, with a low power consumption of only 7 watts and certifications like Energy Star, CE, and RoHS. However, it may not be powerful enough for larger rooms or more severe air quality issues. The need to replace filters every 4-6 months adds to maintenance costs, but an indicator light helps remind you when it’s time. This air purifier is best suited for those looking for a simple, quiet, and portable option for smaller rooms.

The LEVOIT Smart Wifi Air Purifier Core 300S is a robust option for home air purification, especially suited for larger spaces up to 100 m². With a Clean Air Delivery Rate (CADR) of 240m³/h, it efficiently circulates the air in the room, making it effective against pollen, allergens, and smoke. Its 3-stage HEPA filtration system includes a pre-filter, H13 HEPA filter, and an activated carbon layer, providing comprehensive air cleaning by trapping dust, pet dander, and odors.

One of its standout features is real-time air quality monitoring through a laser dust sensor, with results displayed on the VeSync app and indicated by color changes on the device. This smart functionality is complemented by voice control compatibility with Alexa and Google Assistant, making it user-friendly for those who prefer hands-free operation. The Core 300S is notably quiet, operating at just 22 dB in sleep mode, which is ideal for nighttime use without disturbing sleep. It also boasts energy efficiency, with a low energy consumption of 23 watts, making it cost-effective to run continuously.

While the purifier offers a range of stylish features and an award-winning design, it may require frequent filter replacements, every 6-8 months, which could add to the long-term maintenance costs. Additionally, while its features are comprehensive for general home use, its performance might not meet the needs of those requiring industrial-level air purification. This air purifier is perfect for allergy sufferers or households with pets, thanks to its specialized filters and ability to remove common household pollutants. However, users should consider the ongoing cost of filter replacements when evaluating its affordability.

The Shark NeverChange5 Air Purifier is designed for large rooms, covering up to 130 square meters, making it a solid choice for spacious areas like living rooms or open-plan spaces. It uses a certified HEPA filter that can trap 99.97% of common allergens such as dust, pollen, and pet dander, helping to improve air quality for allergy sufferers. One standout feature is its long-lasting filter that can last up to 5 years without replacement under typical use, which can save you money and hassle in the long run. The purifier also uses a 4-layer filtering system and includes an anti-odour cartridge that neutralizes smells and releases a fresh scent, enhancing comfort in your home environment.

The Clean Sense IQ technology continuously monitors air quality and adjusts the purifier’s settings automatically, so you don’t have to guess when to increase or decrease the fan speed. It features a quiet operation mode and dimmable LED lights, making it suitable for nighttime use without disturbing your sleep. The device uses about 54 watts, which is relatively low for its coverage size, helping keep energy consumption reasonable.

Despite effectively covering large areas, the highest air change rate applies to smaller spaces (around 28 sqm with 4.8 air changes per hour), which means in very large rooms the air might not be refreshed as quickly as some specialized units. Its size and weight (around 5.7 kg) make it less portable compared to smaller models. Additionally, while it has an LED display and remote control, it lacks smart home integration that some competing models offer. If you need a reliable, low-maintenance air purifier for large spaces with effective allergen and odor control, the Shark NeverChange5 is a user-friendly option balancing strong filtration with quiet and energy-efficient operation.
