Tommee Tippee Perfect Prep Replacement Filter Pack of 2 sits on our baby feeding shelf, where the ranking comes from what buyers actually said rather than from what the box says. From the seller's own listing: Performing filter for bacterial reduction*: With an ultra-filtration antibacterial membrane. Most standard water filters don’t include an antibacterial filtration membrane. Depending on the amount and size of bottles you use. The performance of other filters deteriorates over time*, ours work like new for up to 3 months**. That is the maker talking, not us, so read it as a claim rather than a finding. Buyers have it at 4.8 out of 5 from 14,353 ratings. We work out below what that is worth against everything else on the shelf.
The typical baby feeding product on our shelf scores 4.7 out of 5, measured across 50 rated products. This one comes in at 4.8. Mid-table, in other words. The stars aren't going to pick a winner here, so it comes down to pack size, cost per unit and the details further down. Weighted for review volume, we place it fifth on this shelf.
That score rests on 14,353 ratings. The median for this shelf is 3,593. A score built on that many opinions is hard to shift and hard to game, which is why we weight review volume rather than ranking on stars alone.
On money, this sits in the top third of a shelf running from £2.28 to £40.95, with the midpoint around £9.66. It costs more than most while rating around the middle, so the extra money needs to be buying something specific: pack size, brand you trust, or a detail below that matters to you.
