Product review (4 stars): Plug and play
This replacement filter fit the bill perfectly. It is intended to replace the DA29-00020A/B.
Swapping out was a breeze and it fit just fine.
You'll want to fill a big glass right off the bat. It will cough and spurt for a minute until all the air comes out. Your first glass will also be cloudy as the charcoal dust gets rinsed out.
We'll see how it does over time. At half the price of the OEM filters, though, I have a tough time seeing how you can lose.
The only reason it got 4 vs. 5 stars is it wasn't Prime Eligible and took 3 days total to get here.
