In-depth Review of Blueair HealthProtect 7470i Air Purifier:
Blueair is an award-winning technology company that designs and manufactures air purifiers. As a well-respected brand, Blueair air purifiers use mechanical and electrostatic filtration.
This helps to trap and remove the large, medium, and small particles as small as 0.1 microns. This is why Blueair air purifiers are ideal for asthma and allergy sufferers.
Here are the top features of the Blueair HealthProtect 7470i Air Purifier.
2-in-1 Particle plus Carbon Filter
Blueair HealthProtect 7470i comes with a thick 2-in-1 particle plus carbon filter as the main filter. The filter comes in a booklet-shaped design, which increases the filter surface area and needs less housing. The signature Blueair HEPASilent technology also produces less noise because of the less dense media filter.
The HEPASilent combines electrostatic and mechanical filtration technologies. Basically, the purifier passes an electrical charge through the filter. This electrically charges the airborne pollutants, which in turn get trapped between the fibers.
The filter removes 99.97% of airborne pollutants as small as 0.1 microns. It traps pollutants such as microplastics, bacteria, viruses, smoke residue, pet dander, and other tiny particulates. The filter has a thick odor filter based on coconut shell activated carbon to neutralize medium to strong odors and VOCs.
The filter has a maximum lifetime of 1 year. By replacing the filter, you ensure the delivery of clean air in your home and remove germs in the air.
Normally, the filters of the air purifiers collect microorganisms along with other contaminants, which are odor-causing bacteria, molds, and viruses. Over time, the odor starts to come out of the filter.
To solve this problem, Blueair HealthProtect has Germshield protection. It stops any secondary pollution from the filter. Even it activates automatically when the purifier detects high levels of pollutions.
The Germshield technology deactivates 99% of those microorganisms trapped in the filter, ensuring no growth of bacteria and mold. So, you will enjoy fresh air day after day out of it.
Download the Blueair app and unlock the smart features of the HealthProtect 7470i Air Purifier. An example is the Clean Air ETA. This feature countdowns until the air is clean thanks to air quality sensors.
Another smart feature you’ll love is the Welcome home function. When activated, it automatically sets the purifier on standby or working based on your geolocation. This feature is convenient, especially when you are in rush.
The main filter has a built-in RFID chip, that tracks the usage of the filter in real-time. It monitors the filter usage based on actual filter loading and room pollution levels. This will let you know when to replace the filters by sending reminders to the app.
On your app, you’ll view useful data such as particle concentration (PM1, PM2.5, PM10), VOC levels, humidity, and temperature. The app also allows you to change the purifier’s settings remotely. You can change settings such as night mode, auto mode, and more on your tablet or smartphone.
You ought to know that the purifier is Amazon Alexa and Google Assistant-enabled. As such, you can use voice commands to control the unit. This is beneficial in that you can change the settings from the comfort of your couch.
Besides the remote control feature with the smart app, the HealthProtect 7470i also has a premium touch control panel with an elegant interface. You can check the air quality metrics, filter status, and change the settings.
Room Coverage and Noise
The HealthProtect 7470i Air Purifier has a CADR of 270 cfm for Smoke, 280 cfm for Pollen, and 275 cfm for Dust. As such, it’s perfect for a medium-sized room. It can clean up to 400 square feet, where you will get 5 air changes in an hour when on the high fan speed setting. Check out more room size recommendations from below.
To deliver clean air to every corner of the room, the HealthProtect 7470i Air Purifier has patented SpiralAir technology. Designed for omnidirectional airflow, the outlets circulate more clean air in all directions. More clean air in the room improves sleep quality (bedroom) and productivity (kitchen or living room).
When running at the lowest speed, the purifier is quieter than a whisper. The purifier’s sound level at this speed is 22 dB, while that of rustling leaves is 20 dB. Since the purifier’s sound level is quieter than a whisper, it’ll not interrupt your sleep.
The purifier’s sound level is 45 dB at the highest fan speed. This is slightly higher than a refrigerator humming (40 dB) but lower than a quiet office (50 dB). At this speed, the purifier will trap and remove germs from all corners of the room and circulate more air.
In Auto mode, the purifier will automatically increase the fan speed if sensors detect a rise in airborne pollutants. By running the purifier at high speed, it removes and even kills more germs. Once the air is clean, the purifier will return to a slower speed. To enable Auto mode, tap the “Auto” button.
