Carbon monoxide is an odorless, colorless gas that is blamed for hundreds of deaths each year. To prevent carbon monoxide-related deaths, many states have carbon monoxide detector regulations in place.
Typical costs:
Stand-alone carbon monoxide detectors typically cost $20-$50. For example, a First Alert digital plug-in carbon monoxide alarm[1] with a backup battery costs $39. A basic battery-operated unit[2] costs $20.
Some carbon monoxide detectors are combined with smoke detectors. Typically, combined units cost $40-$80. For example, BRK Electronics' Battery Smoke/CO Combo[3] costs about $44 at Drillspot.com and includes a remote control silencer and a programmable voice alarm. First Alert's ONELINK combo smoke alarm and carbon monoxide detector[4] costs $70. It allows wireless linking of multiple detectors in one home, which means when one alarm sounds, all the alarms wirelessly linked will sound.
Carbon monoxide alarms for the hearing impaired frequently include strobe lights and cost more than typical alarms. Alarms for the hearing impaired typically cost $100-$130. For example, Drill Spot[5] , an online hardware store, sells a combo smoke alarm and carbon monoxide detector for $129.
Carbon monoxide detectors come with a variety of different features but typically include a hush button (and sometimes a remote-control silencer), a battery backup for power outages, a low-battery warning light and a multi-year warranty. Digital displays often show the carbon monoxide concentration in parts per million. Less common features include voice alarms and strobe alarms (which help the hearing impaired).
Additional costs:
Many carbon monoxide detectors run on batteries, which can cost $5-$10 to replace. Many experts recommend checking the batteries when the clocks are reset for Daylight Savings Time.
Discounts:
Some retailers offer discounts on bulk purchases of carbon monoxide detectors. For example, Walmart[6] sells six detectors for about $100. First Alert[7] also offers discounts, including a combo pack with both a smoke detector and a separate carbon monoxide detector sells for $30. Home Depot sells a pallet of carbon monoxide detectors (256 units) for $9,977, or about $39 each.
Local fire districts and stations frequently have smoke detector and carbon monoxide detector giveaways. Call the local fire department or check their website for details.
