The noise level is quite low for the amount of air I move.
On the lowest setting, I can hear the 400S if I listen for it.
The noise levels are good and it does not distract or drown out the television. However, the highest speed will drown out conversations.
87% appreciated the filter efficiency
The air purifier is good at filtering cooking smoke and some bacteria and viruses.
After using the air purifier for almost three months, the app indicated that my filter efficiency is at 69%.
After using the air purifier, my filter life is at 97%, which I believe is very good.
The air purifier has a filter that can trap airborne particles less than 0.3 microns and 99.9% or more of airborne particles 0.1 microns in size. Additionally, the High-Efficiency Activated Carbon Filter captures smoke, odors, and VOCs, and contains 10x more carbon than competing brands.
82% liked its energy efficiency
The air purifier has smart sensors that automatically change the fan speed based on the amount of filtration/size of particle detected.
The purifier has an auto mode that adjusts its power to meet the environment's needs.
Using fan level 3 or 4 clears the air more quickly and then it can be lowered to fan level 1 or 2 to maintain air quality.
The fan speed increases automatically when the air quality is poor. It's not excessively noisy and reduces soon as the sensor detects the air quality improving.
It took me 8 minutes to reduce the indoor PM2.5 concentration from 35 to 7.
Our air purifiers are energy efficient and we have let them run for 95% of the time without any noticeable spike in our electrical bill.

The purifier only covers up to 400ft, although it was supposed to cover the entire house.
88% found the air purification effective
I love the air purifier because it's important to have one due to the toxins, dust, dirt, and chemicals present in the air around my shouse in the country surrounded by farm fields.
The air purifier can capture 99.98% of airborne particles, eliminate odors, and remove pet hair (depending on the filter model).
After using the air purifier for 24 hours, I experienced a significant improvement in air quality. My head and nose cleared up and my breathing felt cleaner.
I noticed that the air was cleaner to smell and breathe. This indicates that the air purifier was successful in eliminating odors.
The air purifier successfully eliminated odors, making the air cleaner and easier to breathe.
If the purifier removes the smell of my neighbor's laundry soap, I will love it and buy a diffuser for my eucalyptus baths.
