The manufacturer-stated coverage is up to 2,520 square feet in 60 minutes. The separate 1,262-square-foot figure is omitted because its cleaning time or air-change standard could not be confirmed.

Coverage and Performance

The purifier is stated to clean up to 2,520 square feet in 60 minutes. Actual performance depends on ceiling height, floor plan, fan speed, filter condition, placement, pollution level, and airflow between rooms.

The supplied data also lists a 1,262-square-foot maximum coverage figure, but its associated cleaning time or air-change rate has not been confirmed. It is therefore not presented as a verified coverage claim.

Three-Stage Filtration

The filtration system is described as having three stages:

1. Fabric Pre-Filter: Captures larger visible particles and can be washed.

2. Particle Filter: Captures fine airborne particles such as dust, pollen, smoke particles, and pet dander.

3. Odor-Reducing Stage: Helps reduce certain household odors and gases addressed by the filter media.

Only the fabric pre-filter is confirmed as washable. Do not wash the main replacement filter unless the instructions supplied with the product expressly state that it is washable.

The number of fabric pre-filters included in the package has not been confirmed.

Smart Features

The purifier supports Wi-Fi, Bluetooth, and the Blueair App. Available app functions may include operating controls, air-quality information, scheduling, and RealTrack filter-life monitoring.

RealTrack estimates remaining filter life using operating conditions such as:

• Fan speed

• Usage time

• Detected pollution levels

Filter life is stated as up to approximately nine months, but actual replacement intervals vary with usage and indoor air conditions. App compatibility, supported Wi-Fi bands, account requirements, and mobile operating-system requirements should be verified before setup.

Frequently Asked Questions

How much space can it clean?

The confirmed manufacturer claim is up to 2,520 square feet in 60 minutes. Actual results depend on room conditions and placement.

What does the 1,262-square-foot figure represent?

The source information does not confirm the cleaning time or air-change standard associated with that figure, so it is not included as a verified coverage rating.

Does it connect to Wi-Fi?

Yes. Wi-Fi, Bluetooth, and Blueair App support are confirmed.

Is the filter washable?

Only the fabric pre-filter is confirmed as washable. The main particle filter should be replaced rather than washed unless its supplied instructions explicitly say otherwise.

How many pre-filters are included?

The exact number and colors of included fabric pre-filters have not been confirmed.

How long does the main filter last?

RealTrack estimates filter life based on actual operation and pollution levels. Filter life may reach approximately nine months, but the replacement interval varies.

Does it remove 99.97% of particles?

The supplied manufacturer claim states removal of at least 99.97% of airborne particles addressed by the filtration system. This percentage does not mean that the purifier removes every contaminant from an entire room.
