Great machine you can feel the difference quickly unfortunately, in my house I can’t use it on position four as it seems to very much a deal with the electrical circuits in our house and things, rattle and beeping complain but at three it does very very well glad we bought it.
Bought my x5 start of the pandemic. June 2020. Used it in my practice throughout. Was a great comfort. When my wife got Covid we set it up outside her room. As she became symptomatic the particulate readings climbed. Was good to know it was catching the changes. Was a great indicator when I was getting sick or clients were. Used during fire season helped keep out home air quality manageable. I’d get two more if I could.
This is our second Airdog X5. I suffer from allergies and this air purifier helps me tremendously. Coughing is my indicator and if the purifier is not running I cough continuously. Our other air purifier lasted about 6 years but it made it obvious how needed it was when it quit. I went two months without one and then I knew I needed to order another one. Back to living a healthier life with our new Airdog X5!
