The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less.

Overview
The Chemex CM-1C uses the same borosilicate glass construction as the rest of the Chemex line but is scaled down to 0.44 liters, just enough for one large mug of coffee. It accepts a reusable filter and works via manual pour-over, meaning you add hot water yourself over ground coffee at whatever pace suits your technique.
At $41.95, it costs more than many plastic or ceramic single-cup drippers, but the clear borosilicate glass delivers a premium look and resists thermal shock better than ordinary glass. The brewer measures 4.9 x 9.8 x 0.9 inches, which is a notably narrow profile for countertop storage.
With 2,900 reviews at 4.7 stars, it carries solid buyer confidence for a niche personal-sized product. It is not smart-home compatible and requires no electricity, keeping the brewing experience entirely hands-on.

What buyers say
4.7 stars across 2,900 reviews is a strong result for a $41.95 single-cup brewer. Buyer feedback in this category consistently rewards quality materials and consistent brew quality over feature count. Chemex buyers in this size range tend to know what they want and are satisfied when they get it.
It holds 0.44 liters, which is approximately 15 oz or one standard large mug of coffee per brew.
Does the CM-1C come with paper filters?
It uses a reusable filter. Chemex-branded paper filters are sold separately and are compatible if you prefer the paper-filtered cup profile.
Is borosilicate glass worth the price on the CM-1C?
Borosilicate glass handles temperature swings better than standard glass and is less prone to cracking from hot water. For a brewer you use daily, that durability matters at the price.
