Features and benefits

Why I love MIJIA Air Purifier 5

• The MIJIA Air Purifier 5 is equipped with a circular LCD color screen, providing users with an intuitive and real-time display of current air quality information. This immediate visual feedback allows for proactive management of indoor environments, enabling users to understand and respond to changes in air purity effectively.
• With a Particle CADR (Clean Air Delivery Rate) of up to 400m³/h, this air purifier is highly effective for rooms covering an area of 28-48m². This high CADR ensures that the device can rapidly and efficiently purify the air in medium to large living spaces, delivering clean air to every corner of the home in a short period, comparable to the time it takes to read a bedtime story.
• The device boasts exceptional removal rates for various harmful substances, including a formaldehyde removal rate as high as 98.1% in 1 hour and a TVOC (Total Volatile Organic Compounds) removal rate of 92.8% in 1 hour. Furthermore, it achieves a benzene removal rate of 98.00% and a formaldehyde CADR of 150m³/h (single component loading), making it highly effective in mitigating indoor air pollution from new furniture, paints, and other common household sources.
• For allergy sufferers, the MIJIA Air Purifier 5 offers significant relief with a pollen allergen removal rate as high as 98% in 1 hour and a PM10 coarse particles removal rate of 99.98% in 1 hour. This comprehensive filtration targets common allergens and larger particulate matter like dust and sandstorm particles, ensuring a cleaner, sneeze-free environment, supported by sensitive dust and pollen sensor monitoring.
• Beyond filtration, the purifier incorporates advanced antibacterial and antiviral capabilities, featuring a dual antibacterial and antiviral coating combined with ultraviolet UVC real-time disinfection. This powerful combination achieves a 99.99% antiviral rate for influenza A virus H1N1, a 99.98% antibacterial rate for Escherichia coli, and a 99.99% antibacterial rate for Staphylococcus aureus, effectively disinfecting the air and resisting cross-infection within the home.
• Operating at a low noise level of just 30.1dB(A), the MIJIA Air Purifier 5 ensures that air purification does not disturb sleep or daily activities, making it ideal for bedrooms and quiet living spaces. This quiet operation, combined with the delivery of high-quality air, allows for an undisturbed and healthy indoor environment.
• The integrated negative air ionization function, with an anion density of 1,000,000 pcs/m³, actively eliminates stale air and enhances purification, creating an atmosphere reminiscent of fresh forest air. This feature contributes to a feeling of freshness and vitality within the home.
• Designed for convenience and cost-effectiveness, the device utilizes a long-life filter element that can last between 6 to 12 months. This extended lifespan, attributed to a large-area high-efficiency filter and a substantial volume of high-quality activated carbon, significantly reduces the frequency and cost of filter replacements.
• The MIJIA Air Purifier 5 supports smart control via the Mi Home app, allowing users to activate and manage their air purifier remotely. This feature ensures that users can return to a freshly purified home, enhancing convenience and control over their indoor air quality from anywhere, though it requires setting the app region to «China» for connectivity.
• The purifier features an exquisite design with user-friendly maintenance aspects, including a removable top cover for cleaning and a magnetic door design for easy filter replacement. These thoughtful design choices simplify routine upkeep and ensure the longevity and optimal performance of the device.

Authentic Feedback Analysis:
⭐ 5.0/5 | С***ч: Everything is wonderful, it’s easier to breathe, it’s very quiet and it’s big. Works via Alice. The China region is mandatory.
⭐ 5.0/5 | A***k: Delivery was a bit long — it took about 2 months to deliver to Ukraine, and for about a month after leaving China, the parcel wasn’t tracked at all. Then it was delivered quickly, not delayed at customs, no taxes were charged. Communication with the store is excellent, the seller always responds and helps. It was perfectly packed, a Euro plug adapter is included. To connect via the app, you must select Mainland China in the settings — only for this region everything connected. But as it turned out, our air is clean, the indicator was immediately at 9, then dropped to 2-3. In automatic mode, it is almost silent. Temperature and humidity readings are slightly incorrect, but the error is small. Filter resource is 100%, this seller has original filters, analogues can be bought 2 times cheaper but are not original. Ionization can be disabled. After connecting, an update immediately arrived, but I didn’t notice any difference. Overall, a good and high-quality air purifier, they cost more here.
⭐ 5.0/5 | O***Y: China >>>Spain 31€ Custom Charge extra. So keep that in mind. The seller carefully packed the order+++. The item arrived quickly and intact. Version 5. I RECOMMEND the item and the seller!!!
⭐ 4.0/5 | Б***ч: Fully corresponds to the description. Looks good, works quietly, high performance. I can only check the air filtration quality by the readings of other filters (Philips): it filters the air well. Euro plug adapter included. Reliable transport packaging. I lowered the rating for the lack of information in any language other than Chinese. It worked continuously for 2 months. The filter is good. Control is simple and intuitive. The absence of other languages does not interfere with operation. A future problem: the absolute absence of original filter elements for sale, but a good copy can be found (the main thing is with an RF tag).
⭐ 5.0/5 | AliExpress Shopper: Everything works perfectly, delivered in full complete set and intact. Well packed. The instructions are all in Chinese, but it was easy to figure out. Thanks to the seller.

⭐ 5.0/5 | А***ч: Excellently packed, no complaints about the item.
⭐ 5.0/5 | m***e: The item works perfectly, arrived very quickly, however the EU adapter fails, sparks come out when you move it a little, I will look for another cable with a European output.
⭐ 4.0/5 | AliExpress Shopper: Cheaper than domestic products, but has more functions. Quiet.
⭐ 5.0/5 | AliExpress Shopper: Charging 0-100% takes — 5:20 hours 🌚. Capacity received by the lamp — 5180mAh, declared by the manufacturer 5000mAh.
