3 best double filter coffee machines in 2026 (3+ compared)

A double filter coffee machine brews two pots at once by sending hot water to two filter baskets that sit above two separate carafes. Cold water from the tank runs through a heating tube, forms bubbles and rises up the riser pipe, just like in a single machine. A divided outlet then sends it to the left and right shower heads.

Designs differ in how the sides share the work. Models with one 1,000 W heater either alternate between the baskets or feed both at a slower rate, so a double brew takes roughly 12–20 minutes. Units with two tanks and two heating elements let you run each side on its own switch.

Each side ends in its own carafe. On the Klarstein KG13-90300 the jugs are insulated, so neither needs a hot plate after brewing. The Hamilton Beach 49980A-CE uses a glass jug on a warming plate and has a larger 1.8 l tank.

A double filter coffee machine needs roughly 35–50 cm of counter width, about twice a single brewer, plus 35–40 cm of height under wall cupboards so you can open the filter lids. Depth is usually 20–30 cm. Leave a few centimetres free at the back and sides for steam, and measure the gap under your cupboards before you order.

Power use is modest. Most double machines draw about 1 kW, no more than a single 10-cup brewer, so any normal kitchen socket copes. A full double brew uses roughly 0.2–0.3 kWh. Thermal carafes, as on the Severin KA 9252, cut further use because no plate stays on after brewing.

Double filter coffee machines commonly cost about £30-£90, while a typical model sells for around £80. Compact models start at about £30 with an 8-cup rating and a 1 l tank, which is enough for two small pots.

Around £80 the Klarstein KG13-90300 adds 10 cups, a 1.25 l tank and thermal carafes. At about £90 the Hamilton Beach 49980A-CE brings the biggest 1.8 l tank and 12 cups, but with a glass jug on a warming plate.

The chart below shows the price distribution of double filter coffee machines.

Before buying a double filter coffee machine, you should check the following points:

• Independent sides: Separate switches let you brew one pot when only a few people want coffee. Machines that always run both sides waste coffee and water on quiet days.
• Carafe type: Thermal jugs keep two pots hot for 2 hours or more without a hot plate. Glass jugs on warming plates are cheaper to replace but turn bitter after half an hour.
• Tank layout: Two tanks let you brew different amounts on each side. A single shared tank of 1–1.8 l is simpler to fill but splits the water between both pots.
• Counter fit: A double machine is about twice as wide as a single brewer. The space above matters too, since the filter lids need room to open.
• Timer: A timer is useful for meetings or breakfast service. Both pots ready at 7:00 without anyone pressing a button is the main time saver.
• Real cup size: Cup ratings of 8–12 usually mean small 125 ml cups. An 8-cup side fills only about four mugs, which matters when you brew for a group.
