I live in Brooklyn and am currently quarantined to my bedroom with no airflow throughout the apartment so I want to make sure I’m breathing healthy air. I have really bad allergies right now this time of year which cause me to cough a ton. My cough started to go away after the first day of use and by the 3rd day of continuous use, I am no longer coughing! I wish I got this years ago! I’m no longer out of breath from coughing all the time. This will save me money on Botox from all the wrinkles that will form from coughing so it’s worth paying for this air purifier. Also, this air purifier is extremely quiet!
