LG PuriCare™ 360º Alpha Pet Air Purifier.

A.1:   The Single model (AS65GDBY0) is better suited for smaller spaces, with a recommended coverage area of 61.2㎡ (about 660 sq ft).

The Double model (AS10GDBY0) is better suited for larger spaces, with a recommended coverage area of 104.0㎡ (about 1,120 sq ft).

A.2: For a bedroom, study room, or smaller condo living area, the Single model is usually the more practical choice.
For a larger living room, open-plan space, or bigger family area, the Double model makes more sense because it has higher airflow performance, with CADR 810 CMH versus 478 CMH on the Single.  

A.3: Yes. Both models include Pet Care / Pet Mode, which is designed to help deal with pet hair and pet odour more effectively in daily home use.  

A.4: Yes. Both models come with Allergy Care, Multi-Filtration System, and BAF certification for reducing allergy-causing substances via a dust filter. 

They also combine UVnano and Ionizer as part of their air-care setup. 

A.5: Both models share the same listed noise range of 53 / 26 dB (High / Low). 

For most homes, that makes them suitable for everyday use in spaces where a quieter low-speed setting is preferred.  

A.6: Yes. Both models support LG ThinQ, so you can turn on the air purifier remotely and manage it more conveniently from your phone.
