Sub-Zero Air Purification Cartridge-7042798

Arrived broken - this is not activated charcoal...these are clear, broken shards. Clearly this broken glass and may contain mercury per warning label on the box.

The 648 PRO G does not use an air freshener.

Easy to install. I change both filters out once a year. Hopefully that’s correct!

Delivered on time. Easy to install

Works fine in my sub zero fridge. Easy install. Don’t listen to those people who complain about noise when the shake it or dust. That’s the carbon particles mo moving around inside, and sometimes creates dust on the outside, although I didn’t find any dust on mine

I’m very disappointed with my purchase with this seller. This is not a cheap cartridge, I paid almost $70 for it. And this seller sent us a used one, such a disgrace to Subzero brand!

Open seal, box opened, dirty filter, glass in box. Paid full price for a new cartridge, got a dirty, used one. Contains mercury & it’s got particles inside the box!!! Dishonest business practice! Do NOT buy!!!!! Go through the manufacturer directly.

When we got our SubZero and filter replacement time rolled around, we got a filter that said it was comperable to original SubZero filter. Well, my husband looked at the original and compared it to the CHEAP one. He immediately sent it back. Yes, they may be pricey but worth the investment especially since we invested in a high end frig! No regrets AND it may affect your warranty if not using the proper filter.

Filter was dirty with some fine grit, and there was a rattling sound from inside the filter. Small clear plastic pieces were falling out. This is garbage.

Product broken and used. The packaging was torn and obviously previously open. The item is half price at authorized dealers. I dont recommend this product.
