Heat Treatment Technology

Zip-and-purify technology. Zip it closed and sterilize your bed anytime

Heat is known to be very effective at killing bedbugs. 2 Heat also has the advantage of being non-toxic, and can kill all life stages of the bedbug, including the eggs. Studies show that temperatures above 49ºC (120ºF) will kill bedbugs in less than 1 minute. 2 At the lower temperature of 46ºC, all bedbugs will die in less than 6 minutes. 3 The GoodKnight™ uses convective heat to bring the mattress and bedding to temperatures above 50ºC (122ºF) for at least 20 minutes. The treatment is safe, being no hotter than the clothes dryer and effective, killing all bedbugs within the enclosure.

GoodKnight™ Heat Purification: The above cross-section shows how convective heat is distributed around the mattress and bedding.

Other Pests & Allergens

Mold, bacteria and other pests like dust mites are often a major source of indoor allergens. 4 The GoodKnight™ can play a significant role in reducing many of these contaminants in the sleeping environment by killing them with heat. The target temperature of the GoodKnight™, 50ºC (122ºF) will kill 100% of dust mites in 20 minutes. 5 Heat also helps denature asthma-causing allergens, reduces odors and even removes volatile organic compounds (VOCs). The full GoodKnight™ heat-purification cycle lasts 3hrs, giving the convective heat enough time to penetrate into the fabric and other materials, reaching pests that may be deeper in the fabric. Below is a list of pests and the temperature required to eliminate them using the GoodKnight™.
