FAQ
What room size is best for the Classic Pro CP7i?
To achieve maximum performance we recommend placing your Classic Pro CP7i in a 57 m² room so your air purifier can clean the air at the AHAM recommendation of 4 times every 12.5 minutes. The Classic Pro CP7i will clean a 135 m² in 30 minutes, and 270 m² in 1 hour. (All at top speed).
What pollutants does the Classic Pro CP7i filter out?
Our HEPASilent™ dual filtration technology removes 99.97%¹ of airborne particles down to 0.1 microns, ensuring pollen, cooking odours, smoke, dust, pet dander, mould, chemicals, allergen matter and even tiny particles such as viruses and bacteria², are captured with minimal noise and energy consumption.
What is the warranty for the Classic Pro CP7i?
Register your product to extend the 1 year warranty to a 5-year warranty.
How does HINS technology work?
Our patent-pending HINS technology works throughout the day activating every 10 minutes by shining a visible blue light on the filter for 10 second and then turning off to conserve its lifetime.
This visible protection is uniquely different from other lighting technology in air purifier and is achieved because Photon Pure operates in safer wavelength of 405nm.
How often do I need to change the filters?
Your filter will last up to 1 year thanks to our proprietary RealTrack algorithm that accurately calculates the remaining filter lifetime based on fan speed, usage time and pollution levels.
When it's time to replace the filter, the filter replacement LED on the interface will turn red to remind you. Alternatively, connect to the Blueair app to receive an alert and easily re-order at the touch of a button.
Does toggling between the different PM levels (PM1, PM2.5, PM10) on the display change the specific types of pollutants that are filtered out of the air?
While many Blueair units come equipped with a PM2.5 sensor, some models, including Blue Pure 211i Max, Protect 70i, or Classic Pro CP7i, have advanced sensors that measure PM1, PM2.5, and PM10 levels for more precise air quality monitoring. However, the display on these models can only show one of these three particulate matter (PM) values at a time due to the size of the screen. The display can toggle between PM1, PM2.5, and PM10 readings to track the levels of different pollutants in their environment. Switching between these indicators does not affect the air purifier's performance or target a specific pollutant size to remove from the air. The air purifier continuously works to remove particles down to 0.1 micron from the air regardless of which PM indicator is displayed.
