Air vs Magnetic Rowing Machine: Concept2 RowErg vs Merach Q1S
An air rower uses a fan, so resistance rises the harder you pull. A magnetic rower uses magnets at set levels and is close to silent. We compare the reference air rower, the Concept2 RowErg, with our top budget magnetic pick, the Merach Q1S — very different machines at very different prices.
Specifications come from the Amazon listings; owner feedback is summarised from Amazon customer reviews, checked October 2026. We have not tested either machine ourselves.
Concept2
Choose the air rower for serious training and accurate data
Concept2 RowErg · 9.1/10 LiftEvidence editorial score
- Fan resistance with an adjustable damper and the PM5 monitor, whose pace and watts compare directly with other Concept2 rowers.
- Rated to 500 lb, splits in two for storage, and carries 13,079 Amazon ratings with exceptional feedback.
- Trade-offs: fan noise at hard efforts, a 9 × 4 ft space requirement and a premium price band.
Merach
Choose the magnetic rower for quiet, budget-friendly cardio
Merach Q1S · 7.2/10 LiftEvidence editorial score
- 16 magnetic levels that owners describe as very quiet — one says inaudible from the next room.
- A smaller 65 × 19.3 in footprint, a 350 lb rating and the Merach and Kinomap apps, in our budget price band.
- Trade-offs: several owners say the resistance could be stronger, the LCD data is basic, and the listing gives a 1-year warranty.
Resistance and training
Air resistance has no fixed ceiling, which suits hard intervals and race-pace work. Magnetic resistance is set by level, which suits steady cardio; on the Q1S some owners find the top levels light. Our rowing machine buying guide explains the resistance types.
Noise, space and data
We rate the Q1S excellent for quietness and the Concept2 moderate. The Concept2 needs about 9 × 4 ft; the Q1S lists 65 × 19.3 in. For data the Concept2 is the standard — we rate it excellent, the Q1S moderate.
Overall score
Overall we score the Concept2 9.1 and the Q1S 7.2. The Concept2 leads on performance, build and data; the Q1S matches it for value and beats it for practicality.
