Design and Build Quality

The PuroAir 400 HEPA 14 air purifier boasts a sleek, modern design that blends seamlessly into any home decor. Its compact size allows it to fit comfortably in various rooms, from bedrooms to living rooms. The build quality is robust, with a sturdy outer casing that feels durable.

The digital display is clear and easy to read, providing real-time information on air quality, filter status, and operational settings.

Filtration System and Efficiency

At the heart of the PuroAir 400 is its HEPA 14 filter, which is one of the highest efficiency particulate air (HEPA) filters available. This filter is capable of capturing 99.995% of particles as small as 0.3 microns, including dust, pollen, smoke, and pet dander. Additionally, the unit incorporates a pre-filter to capture larger particles and an activated carbon filter to remove odors and volatile organic compounds (VOCs).

During testing, the PuroAir 400 effectively reduced airborne particles in a 400 square foot room within a few hours of operation. The air quality sensor is highly sensitive, and the purifier adjusts its fan speed automatically based on real-time air quality readings. This automatic mode ensures optimal performance without constant manual adjustments.

Noise Levels

One of the standout features of the PuroAir 400 is its quiet operation. On the lowest setting, it produces a gentle hum that is barely noticeable, making it ideal for nighttime use in bedrooms. Even at the highest setting, the noise level remains tolerable, akin to white noise, which can be soothing for some users.

Energy Efficiency

The PuroAir 400 is energy-efficient, with an Energy Star rating that ensures it won’t significantly impact your electricity bill. It consumes only about 60 watts on the highest setting, making it an eco-friendly choice for continuous use.

Additional Features

  • Smart Connectivity: The PuroAir 400 supports Wi-Fi connectivity, allowing users to control it via a smartphone app. The app provides additional functionality such as scheduling, monitoring filter life, and receiving air quality notifications.
  • Child Lock: This feature is particularly useful for families with young children, preventing them from changing settings accidentally.
  • Filter Replacement Indicator: The unit alerts you when it’s time to replace the filter, ensuring the air purifier always operates at peak efficiency.


Maintaining the PuroAir 400 is straightforward. The pre-filter requires periodic cleaning to maintain airflow and efficiency. The HEPA and activated carbon filters need replacement every 6-12 months, depending on usage and air quality. The filter replacement process is user-friendly, with clear instructions provided in the manual.
