Plug-In Smart Carbon Monoxide Detector and Indoor Air Quality Monitor with AA Battery Backup, 2.4GHz Wi-Fi, COPDLQW

Hello. This carbon monoxide alarm conforms to UL 2034 standards. The alarm is designed to sound based on both carbon monoxide concentration and exposure time. At 70 PPM, the alarm will sound after 1 to 4 hours of continuous exposure. At 150 PPM, the alarm will sound after 10 to 50 minutes of continuous exposure. At 400 PPM or greater, the alarm will sound after 4 to 15 minutes of continuous exposure.

Hello. No, it requires a subscription to get more detailed information and recommendations for air quality.

Hello. There are programmable alerts in the app for air quality control but not for low level CO alerts or regular CO alarms. At 70 PPM, the alarm will give a low level alert within 21 minutes of constant exposure and will go off for the full UL standard alarm within 1 to 4 hours of constant exposure. At 150 PPM, the alarm will give a low level alert within 9 minutes of constant exposure and will go off for the full alarm within 10 to 50 minutes of constant exposure. At 400 PPM, the alarm will give a low level alert within 4 minutes of constant exposure and will give the full alarm within 4 to 15 minutes of constant exposure.

This alarm will pick up volatile organic compounds as part of the indoor air quality. Volatile organic compounds (VOCs) are a broad class of chemicals that easily evaporate into the air, and many everyday sources—like cleaners, paints, or even cooking—release them, so a VOC sensor detects the presence and relative concentration of these airborne chemicals. A toxic odor, however, isn’t defined by smell alone; toxicity depends on the specific substance and its concentration, and many dangerous gases have no odor at all while many strong odors are completely harmless. Because a VOC reading only indicates that volatile chemicals are present—not whether any of them are harmful—a VOC sensor cannot determine toxicity, only that something in the air is producing measurable chemical vapors.

Hello. This unit conforms to UL 2034 standards. At 70 parts per million parts of air, PPM, it will go off after 1 to 4 hours of continuous exposure. At 150 PPM, it will go off after 10 to 50 minutes of continuous exposure. At 400 PPM or higher, it will go off after 4 to 15 minutes of continuous exposure. We do have a lower level alarm, the KN-COU-B.

We have had lots of people who have connected this alarm to the Kidde App. Please call us at 1-877-542-5471 when onsite with the alarm we can help you connect the alarm to the app. Please note the unit will not connect to wi-fi when unplugged.

Hello. Thank you for reaching out. If soot entered your basement during the chimney liner installation, it’s understandable to be concerned about air quality. While we can’t provide specific health or safety advice, our air quality and carbon monoxide alarm is designed to help monitor indoor conditions, including Total Volatile Organic Compounds (TVOCs), Carbon Monoxide (CO), Temperature, and Relative Humidity. For general use, we recommend placing the device in the area of concern and allowing it to run for a period of days to gather readings. If the device detects elevated levels, it may be a sign that further ventilation or professional assessment is needed. Please note: This device is intended to support awareness of indoor air conditions, but it should not be used as a substitute for professional air quality testing or safety inspections. Let us know if you have any questions about setup or usage—you can call us at 1-800-880-6788.

Would this pick up wall paint oder issues

Hello. This is not something we have tested ourselves. Vape smoke isn't usually going to create enough carbon monoxide to set off the alarm for carbon monoxide. The alarm might read the vape smoke as a volatile organic chemical and it might raise the total volatile organic chemical amount (TVOC) readings in the app. It might lower the total air quality readings. It won't give off an alarm. This is not a vape smoke alarm detector.
