The Problem with Paper Filters
Filter collapse lets fine grounds slip into your cup and creates a mess in the basket.
Internal support prevents collapse, keeping your brew clean and consistent.
How It Works
Four simple steps to better coffee
Place Filter
Set a paper filter in your coffee maker's basket
Insert Coffee Cage
Position inside the filter, legs facing down
Add Grounds
Measure your coffee as usual
Brew Clean
Coffee Cage supports the filter throughout brewing
Easy to Clean
Rinse under running water or toss it in the dishwasher—done. A quick swipe with mild soap lifts any oils if needed.
Unlike plastic or silicone retainers that trap odors or degrade over time, Coffee Cage is made from food-safe 304 stainless steel. Dishwasher-safe and built to last a lifetime.

Frequently Asked Questions
Will Coffee Cage affect the taste of my coffee?
No. Coffee Cage is made from food-safe 304 stainless steel and rests inside the paper filter, so it doesn't add any flavors or aromas to your brew.
If you notice a change in taste, it's almost always due to grind size, water quality, or dose—not the insert.
How do I size the legs?
Bend the legs down a little at a time until Coffee Cage sits level inside the basket. Small adjustments go a long way, and you can always bend them back slightly if needed.
Aim for a snug-but-comfortable fit that doesn't rub the basket walls when placed inside the paper filter.
How do I clean it?
Right after brewing, lift Coffee Cage out, tap off any loose grounds, and rinse under warm water. If oils build up over time, a drop of mild dish soap takes care of it quickly.
That's it—easy upkeep for daily use.
Does it change brew time or flow?
Brew time should remain about the same. Coffee Cage supports the paper and keeps pathways open, allowing water to pass freely beneath and around it.
If you notice slower flow, check for an overly fine grind or an overfilled filter—those are the usual culprits.
Is it dishwasher safe?
Yes—completely dishwasher safe. 304 stainless steel isn't affected by typical dishwasher heat or detergents. Top rack is fine; avoid harsh abrasives just to preserve the finish.
Will it rust or leach metals?
No. Coffee Cage is made from food-safe 304 stainless steel, which is corrosion-resistant and non-leaching.
If you ever see light discoloration from mineral deposits, soak briefly in warm water with a splash of vinegar, then rinse.
