10 Best Quiet Treadmills 2026 in the United States

The NordicTrack T Series 10 treadmill is a solid choice for anyone looking for a quiet, space-saving treadmill with smart workout options. It features a 3.6 horsepower motor that can handle speeds up to 12 MPH, making it suitable for walking, jogging, and running. The 20-inch wide and 60-inch long deck provides a comfortable running area, while the aluminum frame supports up to 325 pounds and feels sturdy without being overly heavy. One of the highlights is its foldable design, which makes it easy to store in smaller spaces, and the assisted lowering mechanism helps avoid sudden drops.

This treadmill offers a 0-12% incline range to add workout variety and helps engage more muscles. The SelectFlex cushioning lets you adjust the deck’s firmness, which can reduce impact on your joints and contribute to quieter operation. While specific noise reduction features aren’t detailed, the combination of a well-built frame, decent rollers, and cushioning generally helps keep noise at a manageable level for home use.

The 10-inch tilting touchscreen integrates with iFIT, providing access to thousands of workouts and smart features like automatic speed and incline adjustments. However, many of these advanced features require a paid membership, which is something to keep in mind. Bluetooth heart rate monitoring support is a plus for tracking fitness more closely. Some users might find the treadmill a bit heavy to move frequently despite the foldable design, and the motor, while sufficient for most home users, isn’t the quietest on the market when running at top speeds. Assembly is required, which could be challenging for some. The NordicTrack T Series 10 treadmill performs well as a quiet treadmill for home fitness enthusiasts who want smart workout integration and space-saving design. It balances comfort, performance, and technology, though advanced features come at an extra cost and it may produce moderate noise during intense sessions.

The NordicTrack T Series 5 treadmill is designed for those looking to enjoy their workouts with minimal noise disruption. It boasts a high-quality motor with a speed range of up to 10 miles per hour, making it suitable for both walking and running. The KeyFlex cushioning adds comfort by reducing impact, ensuring a pleasant experience for users during exercise. The incline mechanism allows for a 0-10% incline, which is beneficial for simulating outdoor terrain and targeting different muscle groups.

One of its standout features is the iFIT technology, offering personalized coaching and heart-rate monitoring. This can enhance your workouts significantly, adapting to your fitness level automatically. The 5-inch LCD display is handy for tracking your progress, although it might feel a bit small for some users, especially when compared to larger models.

In terms of noise reduction, this treadmill performs well, making it a great option for apartments or shared living spaces. However, potential buyers should be aware that assembly is required, which might be a hurdle for some. The machine is relatively heavy at 130 pounds, so moving it around could be a challenge without assistance. While the T Series 5 has a robust design and good performance, its weight and the need for assembly are factors to consider. It could be a perfect fit for fitness enthusiasts who appreciate the combination of technology and comfort but might not be ideal for those seeking a lightweight, ready-to-use option.

The THERUN Treadmill offers a smooth and quiet workout experience thanks to its upgraded 3.0 HP brushless motor, which runs with less friction and noise compared to standard motors. It operates at under 20 decibels, making it suitable for home use without disturbing others. The treadmill includes a 12% auto incline feature to simulate uphill running, helping you burn more calories efficiently. The running area is spacious (47.2" by 17") with a double-deck design and shock-absorbing pads that reduce stress on your joints, supporting users up to 300 pounds.

Its foldable frame is compact and easy to store, saving about two-thirds of the space compared to regular treadmills. The hydraulic system helps safely unfold it in seconds without effort. The LED display shows all essential workout stats and heart rate sensors add convenience. On the downside, its top speed is 8.7 MPH, which is fine for walking and moderate running but might not satisfy serious runners seeking higher speeds. The warranty is 1 year, which is average but shorter than some premium models.

This treadmill is a solid choice if you value quiet operation, space-saving design, and incline training at home, though it may be less ideal for very intense running or long-term heavy use without extended warranty coverage.
