It has a three-stage filtration system that includes a true HEPA filter to capture even the smallest airborne contaminants in rooms up to approximately 400 square feet.
It also has a built-in precision laser sensor that accurately monitors particles in the room and automatically adjusts fan speeds as needed. The purifier is incredibly quiet, working at only 24 dB, which makes it ideal for bedrooms. The Oransi mod has a decibel range of 19-45 dB while the MA-112 has a decibel range of 21-48 dB. The A3 has a noise range of 19-52 dB and Levoit LV-H134 covers up to 710 square feet with a CADR of 312 CFM and generates noise in the 18-45 dB range. Pure 211+ has 350 CFM CADR and generates noise in the 22-45 dB range while Coway 1512 has 360 m2 coverage area with 20-54 dB noise range.

After taking a baseline measurement, we let the air purifier work at the maximum setting for 1 hour and take another measurement of the air quality in the room to compare it with the reference measurement. Many air purifiers offer convenience features that improve usability but don't affect air purification performance. The Core 300 produces lower airflow than the Mighty at 135 CADR compared to the Mighty 240 and is not suitable for living room-sized spaces where the Mighty excels. It is best to buy an air purifier for each room or move a single purifier with you if you want to clean the air in both living room and bedroom. Choosing an air purifier with more coverage area than your exact room size will allow you to use it in lower consumption mode or increase the number of clean air changes per hour. That's enough to remove up to 99.97% of common airborne pollutants in 540 square feet, which is ideal for family room, master bedroom or large office.
The Core 400S has all essential features you want in an air purifier, namely a HEPA filter, CADR certifications from Association of Appliance Manufacturers and noise range of 19-46 dB. It is advisable to “oversize” your air purifier so that you can run it in slower and quieter settings while still cleaning the air in your room effectively. But make sure to keep windows and doors closed so that your unit does not clean the air outside or other parts of your house. In conclusion, Coway AP-1512HH Mighty is an effective, efficient and affordable air purifier while Levoit LV-H134 offers intelligent capabilities like Levoit app which allows you to monitor air quality in real time, view filter life and set schedules.
