Canada, Eh!!
Doh!!

Just bought 3 from Lowes.ca last week. Cost bit less because of $10 coupon and the combo alarms they sell are photoelectric... since already have some ionization smoke alarms figure good to have a mix.

But only 7 years vs Coscto 10 years.

Got 3 similar ones from Lowes for $32.49/each and installed them all last weekend. Great deal if you need these.

So which are better? Ionization or Photoelectric?

The sale is over but they were these ones

They are not the same as the Costco ones which are ionization and mine are photoelectric.

"One is a “fast flame” fire, the other is for smoldering fires. ... In tests, ionization alarms will typically respond about 30 to 90 seconds faster to “fast-flame” fires than photoelectric smoke alarms. However, in smoldering fires, ionization alarms respond an average of 15 to 50 minutes slower than photoelectric alarms."

15-50 min? I hope that's supposed to be seconds.

OP should put this in thread title. I thought this was a great deal like the Lowes one until you pointed out that it's not the same model.

@Matrix_dot_ca

I would assume that it is recommend that at least on sleeping level you have one of each type (photoelectric & ionization)?

This may sound like a stupid question, but these mount on the ceiling? Isn't it likely that by the time Carbon Monoxide gets that high in your house, you're already dead?

That's why I prefer the plug in ones that you can use on a plug close to the floor. You will wake up once you breathe in smoke , you won't with carbon monoxide.
