Winix C610 Air Purifier for $99.97 at Costco

Costco is offering the Winix C610 air purifier for $99.97, down from the original price of $130. This deal is notable because the price in-store is significantly lower than the online price and the refurbished version is available for $60, though this new model includes a second filter and air quality sensors. The discount is roughly 23%, and considering Costco's easy return policy and genuine filters included, this deal offers good value. The retail price has been reduced by about $30 from the original, making it one of the better deals recently seen for this product, especially when purchasing new with the added filters and sensors.
