10 Best Quiet Treadmills 2025 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.

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 MERACH Foldable Treadmill is designed for home users who want a quiet and efficient running machine. It features a motor that supports speeds up to 7.5 MPH and a 15% automatic incline, which helps increase workout intensity and calorie burn. The belt is notably wide at 16.5 inches and uses a 5-layer design combined with six shock-absorbing pillars, making it gentle on your joints—important for comfort and injury prevention. The frame is made of alloy steel, providing stability and supporting up to 300 pounds, which means it can handle most adult users easily.

The treadmill folds compactly and uses a hydraulic lever, so it’s easy to store without taking up much space. Rollers and the deck use double-deck technology with silicone shock cushions, contributing to smoother motion and less impact noise. Noise is kept very low, below 40 decibels, making it suitable for use in apartments or during quiet times at home. You also get useful features like heart rate monitoring, an LED display, and even an app to make workouts more engaging.

Assembly is required, which might take some time, and while the machine is quiet, the 105-pound weight means it’s not super lightweight to move frequently without assistance. This treadmill is a solid choice if you want a quiet, foldable machine with good incline options and joint protection, ideal for home workouts where space and noise are concerns.
