We have 2 boxers, we love them but they shed and can be gassy. I also have allergies that cause me to be miserable. Within 2 hours of plugging in our Winix air purifier not only am I breathing better our house started smelling cleaner. The pet hair and pet dander has been, no joke 80% less. Instead of dusting daily I am down to once a week dusting. Not only do I thank you as my allergies are better but my OCD cleaning thanks you as well lol. This air purifier is a life changer. I plan on buying one for every room in my home!
