Monoxide detector 7 year shut down?

Hello, can you help me find a brand of monoxide detector that doesn't shut down in 7 years? I'd like a plug in one. They cost 30-50 dollars and then before you know it the things not good anymore. I had 2 battery ones, now the last one is chirping its replacement signal. I am not trying to be cheap with safety...I just think its another gimmick to get consumers to spend. Thank you.

Generally speaking most brands have detector failure within 5 - 8 years or so. They just get all gummed up with what's in the air in our homes. If you smoke in the house or have pets or a poorly maintained forced air system, failure can occur sooner. Good practice & required by some insurance companies is replacement within that 5 - 8 year period. Sorry to burst your bubble on something that last's forever as no one has invented a self cleaning detector yet.

It's not dust or dirt, the chemical sensor in the CO detector wears out. This is not like a smoke detector which can be vacuumed. This is one reason I use separate smoke and CO detectors.

Kidde has just released a 10 year co detector. This is an industry first. Ul requires that your co alarms at the end of life which had been 7 years and now will be ten years.

Btw, it is a good idea to vacuum your smokes but regardless nfpa recommends your replace them after 10 years regardless.

I just had to replace one that failed after 3 years.

It was a Kiddee plug in model.

Should return it under warranty. The date code is on the unit

I have it sitting on a shelf and am waiting to do it.

Time is the limiting factor on most things I do.
