How to Choose a Countertop Dishwasher Under $300
Tank vs. faucet hookup
Tank models (EUHOMY, Hermitlux, NOVETE, AIRMSEN, COMFEE Mini) let you fill water by hand – ideal for renters and RVs. Six-place models (COMFEE CDC22P1BBB, BLACK+DECKER) connect to the faucet.
Capacity
Tank models hold about 30–40 items (4–5 place settings). For 2–3 people or bigger loads, choose a 6-place model that fits up to 70 pieces.
Size and clearance
Measure the space under your cabinets: tank models are about 18 inches tall, and COMFEE recommends at least 19.6 inches of clearance. Six-place models are about 22 inches wide and 46 pounds.
Noise
EUHOMY lists 40 dB and AIRMSEN 45 dB; most others list 50–62 dB.
Programs and drying
Look for hot-water cycles (162–167°F) for baby items and greasy dishes, and hot air drying with ventilation to prevent odors.
Warranty
Most offer 1 year; AIRMSEN offers 2 years.
