10 Best Air Purifiers

The Levoit Core 300 air purifier is a solid choice for medium to large rooms up to 80 square metres, making it suitable for most bedrooms, living rooms, or home offices. Its Clean Air Delivery Rate (CADR) of 187 m³ per hour means it can refresh the air effectively—either once an hour for larger spaces or twice an hour for smaller ones, ensuring better air quality. It uses a three-stage filtration system including a true HEPA filter, activated carbon, and a pre-filter, which together remove 99.97% of common indoor pollutants like dust, pollen, pet hair, mould spores, and odors. This makes it especially helpful if you have allergies or pets. Four different filter options are available to target specific needs like toxins or bacteria, adding versatility.

Noise levels are impressively low thanks to QuietKEAP technology, with just 24 decibels in sleep mode, so it won’t disturb your rest. However, it is corded and not wireless, so placement depends on proximity to a power socket. Energy consumption is moderate, typical for devices of this type. Maintenance involves replacing the filters every 6 to 8 months, which is straightforward but an ongoing cost to consider. The unit also has convenient features like a timer, multiple fan speeds, and a filter replacement indicator. One plus is that it does not produce ozone, which some air purifiers do and which can be harmful.

Its size and performance suit bedroom or home use well, though it may be less ideal if you need a portable or very quiet device for smaller spaces. The Levoit Core 300 is a reliable, easy-to-use purifier that performs well in removing allergens and improving indoor air quality for typical UK homes.

The Levoit Vital 100S is designed to clean the air in medium to large rooms, covering up to 1120 square feet with a strong CADR of 243 m³/h. This allows it to refresh the air in a smaller room (224 sq ft) up to 5 times an hour, effectively managing allergens, dust, pet hair, and smoke. Its three-stage filter system includes a washable pre-filter that extends the life of the main HEPA and activated carbon filters, which remove 99.97% of tiny particles and neutralize odors. This setup helps save money over time since the HEPA and carbon filters only need to be replaced roughly every 8 to 12 months.

In terms of noise, it performs excellently with a quiet sleep mode at 23 decibels, making it suitable for bedrooms without disturbing rest. The energy consumption is modest at 32 watts, keeping electricity costs low. Smart features include an accurate air quality sensor with color feedback, app control via VeSync, and voice commands through Alexa or Google Assistant, providing convenient remote management. The unique Pet Mode enhances cleaning efficiency for homes with animals by focusing on pet hair and larger particles. Some advanced features like Pet Mode require app use, which may be less appealing for those preferring simple manual controls.

This purifier is an excellent choice for allergy sufferers, pet owners, and anyone seeking a low-noise, smart air purifier with efficient coverage and easy maintenance.

The LEVOIT Core 400S Air Purifier is designed for large rooms up to 83m² and is equipped with a high CADR of 400m³/h, making it efficient in cleaning air quickly. It features a 3-stage HEPA filter, which is excellent for capturing dust, pollen, pet dander, and other tiny particles, making it ideal for allergy sufferers. The 360° air intake design ensures that it purifies the air evenly in a room, and the PM2.5 air quality sensor helps the unit automatically adjust its settings based on the detected air quality, which is very convenient.

The noise level is impressively low at 24 dB in sleep mode, ensuring it won't disturb your rest. It is also energy-efficient with a wattage of 38, which should keep running costs down. Additionally, the smart features such as Alexa compatibility and the VeSync app provide user-friendly control from anywhere. Maintenance is straightforward with a filter replacement recommended every 12 months, and the product comes with a two-year warranty for added peace of mind.

However, some users might find the initial cost and the size (27.4 x 27.4 x 51.9 cm) a bit bulky. Also, while the smart features are a plus, they might be overwhelming for someone who prefers a more straightforward, manual operation. Despite these minor drawbacks, the LEVOIT Core 400S is a robust choice for anyone looking to improve their home’s air quality effectively.
