We offer free standard shipping to every province and territory in Canada. No minimum purchase is required, and all orders include tracking for your convenience.
You may return most new, unopened items within 30 days from delivery for a full refund. We'll also pay the return shipping costs if the return is a result of our error (you received an incorrect or defective item, etc.).
You should expect to receive your refund within four weeks of giving your package to the return shipper, however, in many cases you will receive a refund more quickly. This time period includes the transit time for us to receive your return from the shipper (5 to 10 business days), the time it takes us to process your return once we receive it (3 to 5 business days), and the time it takes your bank to process our refund request (5 to 10 business days).
If you need to return an item, simply login to your account, view the order using the "Complete Orders" link under the My Account menu and click the Return Item(s) button. We'll notify you via e-mail of your refund once we've received and processed the returned item.
Deliveries to Canada’s outer and remote regions may experience seasonal delays caused by severe weather or limited carrier availability. We appreciate your patience and recommend allowing additional time for your order to arrive safely.
Compact, lightweight, and built for everyday safety, this 4-in-1 monitor blends carbon monoxide detection with humidity and temperature sensing, plus a built in flashlight. It serves as a versatile environmental companion for travel, home, camping, and more. This is a consumer safety monitor, not a medical device.
The device detects carbon monoxide from 0 to 1000 ppm, humidity from 0 to 100 percent RH, and temperature from 14 F to 131 F. Readings refresh every 3 seconds after startup, so you get a near real time sense of air conditions.
Color coded feedback helps you gauge risk at a glance: green for low, yellow for low-to-moderate, orange for rising levels, red for high. The device starts monitoring in about 35 seconds.
Designed for travel and tight spaces, the detector measures 3.8 x 2.2 x 1.2 inches and weighs 0.35 lb. A 2000 mAh battery powers the device, with USB-C charging that takes about 3 to 4 hours. It offers up to 300 hours of standby time when idle.
One button switches temperature display between Celsius and Fahrenheit. The backlit display provides clear readings in challenging lighting conditions.
Reliable, travel ready CO detector crafted by Lwuey. Use it to stay informed about air conditions wherever you are, when you need it most.
