Most items are warranted by their respective manufacturer for 12 months against defects due to manufacturing flaws. Certain items have a longer or shorter manufacturer’s warranty. Some items are disposable and therefore are not warranted for any period of time. These items include but are not limited to air filters and humidifier pads. We do not warranty any item which has been subjected to improper handling, shipping, neglect, abuse, unauthorized repair, modification or alteration. Warranties do not cover products that have physical damage. All warranties expressed or implied are provided by the “manufacturer” of the item you purchased “not” this website or its owners. Contact us to exchange or repair your item in the warranty period.
