Short answer: under $50 a cold brew maker is a vessel and a filter, and that is enough. The National Coffee Association's cold brew recipe is a coarse grind at 1:4 to 1:5, water at room temperature or cooler, and about 12 hours of contact (NCA, cold brew). Nothing in that list requires a motor, a pump or a power cord.
So the decision at this budget is filter material and how easy the thing is to clean, because you will be dealing with a heavy, saturated bed of grounds every time you brew.
What to require in a sub $50 cold brew maker
| What to check | Why it changes the cup | What to require |
|---|---|---|
| Filter material | The NCA describes cloth as absorbing more oils and sediment than metal, less than paper. | Pick for the texture you want, then maintain it |
| Capacity matched to the ratio | At 1:4 to 1:5 the grounds take up real volume. | Room for the grounds plus the water |
| Filter removal | You are lifting out saturated grounds. | A basket or bag that lifts clear in one piece |
| Fridge fit | The NCA has cold brew steeping at room temperature or cooler for about 12 hours. | Fits a shelf with the lid on |
| Cleanability | Coffee oils build up on every surface. | Wide mouth, dishwasher safe parts |
| Seal | An open vessel picks up fridge odors; coffee is hygroscopic (NCA, storage and shelf life). | A lid that actually closes |

The numbers the maker has to hit
The National Coffee Association publishes the recipe this equipment has to execute: a coarse grind, a ratio of 1 gram of coffee to 4 or 5 grams of water, water at room temperature or cooler, and about 12 hours of contact. It also notes steeping times vary widely in practice, from a few minutes to 12 to 18 hours or more overnight (NCA, cold brew).
Filters are the only part that changes the drink
Filter material is the one part of a cold brew maker that changes the drink. The NCA describes cloth filters as absorbing more oils and sediment than a metal filter and less than a paper filter, which is why they often taste smoother. Paper filters can leave a papery taste, so the NCA suggests rinsing any paper filter before brewing. Cloth filters need maintenance: the NCA says to boil them in fresh water for 10 minutes every six to eight weeks (NCA, cold brew).
The mistake buyers make at this budget
Grinding too fine. Cold brew is a coarse grind in the NCA's chart, the same as French press, because the contact time is measured in hours rather than minutes. A fine grind in a 12 hour steep gives you sludge and a heavy, bitter cup, and no filter fixes it.
The NCA gives you a taste diagnosis to work from: coffee that tastes bitter or sour may be ground too fine, which is over-extraction, so the fix is a coarser grind (NCA, drip coffee).
Descaling is the maintenance job people skip. The NCA advises descaling a coffee maker at least every three to six months, and says the right method varies by machine, so follow the manufacturer's instructions (NCA, drip coffee).

FAQ
Do I need a dedicated cold brew maker?
No. The NCA's cold brew method is coarse grounds, room temperature or cooler water at 1:4 to 1:5, and about 12 hours. A dedicated maker mostly saves you the straining step.
What ratio and time does cold brew need?
The NCA publishes 1 gram of coffee to 4 or 5 grams of water, a coarse grind, water at room temperature or cooler, and about 12 hours of contact. It also notes real steeping times range from a few minutes to 12 to 18 hours or more.
Does the filter material change the taste?
Yes. The NCA describes cloth as absorbing more oils and sediment than metal and less than paper, which often makes it taste smoother. It recommends rinsing paper filters before brewing to avoid a papery taste, and boiling cloth filters in fresh water for 10 minutes every six to eight weeks.
