The Acer Acerpure Cool C2 2-in-1 Smart Air Purifier & Circulator (model AC551-50W) is the first air purifier I’ve had the opportunity to review from Acer.
While Acer may not be widely known for air purifiers, they have been expanding into various niches, including e-bikes and even a desk bike similar to the Flexispot Sit2Go.
The Acerpure I’m reviewing today stands out as an excellent air purifier due to its solid performance and affordable price point. However, there is a concern about the availability of HEPA filters in the UK.

### Unboxing / Design
The unboxing process is simple, with the main unit, HEPA filter, and power cord included in the package. The filter is easy to install, and the device is ready to use within minutes of unboxing.
The HEPA filter comes pre-fitted into the air purifier, but you will need to remove the plastic packaging.
### Acerpure Life App
The Acerpure Life app, available for both iOS and Android, offers a user-friendly interface for controlling and monitoring the device. Users can adjust purifier and circulator settings, view real-time air quality data, and receive filter replacement reminders.
I encountered some connectivity issues when trying to connect the Acerpure to my network. It took a few attempts before successfully connecting, which may have been due to my network setup.
The app’s interface is intuitive and responsive, making remote navigation and control of the device seamless. The ability to monitor air quality data and receive filter replacement reminders is particularly helpful for maintaining optimal performance.
### Air Purifier Performance
The Acerpure 2-in-1 is designed to handle spaces up to 45 m² with its 4-in-1 HEPA filter system capturing particles as small as 0.3 microns. During testing, the purifier effectively maintained indoor air quality, showcasing:
#### Filtration Efficiency
The HEPA Plus+ filter captures particles like dust, pollen, and pet dander, while the activated carbon filter removes odors and VOCs.
#### CADR
With a CADR of 307 m³/h, the Acerpure 2-in-1 efficiently circulates and purifies the air within the specified coverage area. It significantly reduces airborne contaminants within an hour of operation.
I used the Acerpure in my office for a couple of weeks and found its performance to be satisfactory. The air purifier outperformed my Dyson Pure Cool Tower Fan but fell slightly behind the Xiaomi Smart Air Purifier 4 in terms of air quality improvement.
### Air Circulator Performance
The air circulation feature, though beneficial, is limited by the small fan size, resulting in higher noise levels compared to pedestal fans. However, the air circulator boasts multiple speed settings and an airflow distance of up to 12 meters for comprehensive coverage.
### Noise Levels
The Acerpure 2-in-1 operates quietly at 25dB on its lowest setting, making it suitable for bedrooms and offices. Even at the highest setting, the noise level of 56dB remains manageable. The fan noise is minimal when the air quality is good but can become louder when higher particulate matter levels are detected.
### Replaceable HEPA Filters
The HEPA filter has an approximate lifespan of 3000 hours, equivalent to around 125 days of continuous use or 375 days of 8-hour daily use. Replacement filters are available on Amazon for £55, but high shipping costs may deter some buyers. Filter availability varies by region, with better access in Asian markets.
For context, the Blueair Blue Max 3250i HEPA filter costs just £35.
### Price and Alternative Options
The Acerpure Cool 2-in-1 is competitively priced on Amazon and Appliances Direct, offering an affordable option compared to its competitors like the Xiaomi Smart Air Purifier 4 Pro and Blueair Blue Max 3250i.
### Verdict
The Acerpure 2-in-1 Air Circulator and Purifier (AC551-50W) is a value-for-money device that effectively combines air purification and circulation functions. Its performance is on par with higher-priced models, making it a compelling choice for many users.
However, potential buyers in the UK should consider the availability and cost of replacement HEPA filters before making a purchase decision. The Acerpure 2-in-1 is a strong recommendation where filter accessibility and affordability are not major concerns.
The decision between the Acerpure 2-in-1 and alternatives like the Blueair Blue Max 3250i will depend on the importance of the air circulator function and willingness to invest in more expensive replacement filters.
