Because it doesn't belong to a big travel company I want to make sure that my safety hasn't been compromised with any leaky boilers!!! I read a few horror stories a few years ago about people being poisoned in holiday villas so I always take a carbon monoxide alarm away with me and this is the best that I have found so far.Why? Because this is a simple plug-in, but a fully functional alarm.Many have to be wired in, but this is going to be so convenient.This is an absolute must if you use coal fires or calor gas fires at home because something as simple as a blocked chimney can fill your room with dangerous fumes that you can't smell, but can kill you. My neighbour lost her sister due to a leaky calor gas fire and I've never forgotten that, so I can sit at this an absolute must when I use mine.A good buy. Every Home Should Have One. ### ⭐⭐⭐⭐⭐ Good, Minimalistic Detector *by R***R on 27 August 2022* Most of the other carbon monoxide detectors I have used had screens which displayed CO levels. This detector has no display and only 1 LED that changes colour. This along with the white finish gives it a very minimalistic look.The detector is also quite good quality and comes with the 2 AA batteries that are required to operate it. I have mine sitting on a shelf in my kitchen so I didn't need to mount it anywhere, this meant that I was all set up and ready to go within a few minutes.If you are looking for a simple, neat CO detector, this is a great choice. ### ⭐⭐⭐⭐ Compact Carbon Monoxide detector *by G***0 on 2 September 2022* Having a rental property we are obliged to provide CO detectors to keep our tenants safe. We have a sealed 10 year unit near the boiler in one of the bedrooms but decided that another unit in the living area would be a good idea, even if not legally necessary.Being quite compact this unit is very good for this purpose as it isn't too obtrusive. It is easy to fit, just needing a couple of small screws and plugs (provided) to attach it a wall. It is worth mentioning here though that you should check out the recommendations for installation, as it would be easy to put it in an area where it wouldn't necessarily detect a build up of CO until it was too late.There are two downsides to this unit though, one is the price, which at the time of writing is £24.99 there are similar units available at lower prices, the second is the batteries, they are AAs and will need replacing well before the 10 year life of the detector has been reached, although at least there is a low battery warning alarm. Personally I prefer those with sealed 10 year batteries, especially as they can be bought for less than the price of this one. ## Frequently Bought Together - HEIMAN Carbon Monoxide Alarm Detector EN 50291 Certified, CO Alarm Detector, Battery Powered, 10 Year Sensor, (720ES) - Smartwares smoke detector - Optical sensor - Test button - 85 dB - 10.044.62 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/455526871-heiman-carbon-monoxide-alarm-detector-en-50291-certified-co-alarm](https://www.desertcart.tn/products/455526871-heiman-carbon-monoxide-alarm-detector-en-50291-certified-co-alarm) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-25*
