Hi guys just wanna some opinion which air purifier should I get for my house. I'm staying in 900 sq ft apartment and I have 2 cats. Im thinking to get either SHARP or COWAY. Any recommendation on which model should I get? (If possible with the model code or name).Im planning to put the unit in the living room to eliminates the 'pet' odour. Hope to hear from you guys soon.Thanks in advance
