It features the patented 360-degree airflow technology for proper air absorption and circulation so that regardless of its position in the room, it performs equally good. Its efficiency is further enhanced by the fact that there are 3 fan modes provided so that you tailor its performance to your needs at any given moment. Perhaps the most important aspect of an air filter is the AHAM certification, which is strongly connected to the CADR that determines its performance. The higher the number, the higher the efficiency, and for this system, the 250 score for smoke, dust, and pollen removal speaks for itself, ensuring it can handle areas up to 390 sq. ft. without much effort.

As for noise, you must know that this device is rather noisy, so if you have a problem with that, you will have to think about it thoroughly. On the highest speed, it makes an annoying noise that can be disturbing, but it minimizes as you choose a lower speed. There is a major drawback regarding its energy consumption, which is the lack of an Energy Star rating that would have placed it among the more energy-efficient systems in its niche. This doesn’t mean that it will become the highest consumer in your house, but combined with the lack of an auto shut off feature or a standby feature, it could reach 200 watts at the high speed.

The true HEPA filter helps it eliminate almost 100% of the impurities existing in the air, including small-size particles, which benefits people who are affected by allergies and asthma, as well as small children who are prone to respiratory diseases. Among the features it includes are:

  • The carbon activated pre-filter makes it even more efficient as it increases the range of pollutants it retains
  • Extra filter protects the HEPA filter from getting filled with lint and fur, so it will last longer. Moreover, you can simply vacuum it to keep it clean rather than having to replace it
  • The high CMF proves the efficiency and reliability and make it a great aid in keeping a clean and safe house


It measures 18” by 18” by 19” and it weighs 21 pounds, so make sure that you have sufficient space for it. It’s a portable device but doesn’t come with rolling casters, so you will have to lift it when you need to move it in another room. It’s a round-shaped device and it is available in a white solid plastic finish with the control knobs and a handle located on the top. It is built using the SurroundSeal Technology that helps minimize air leaks in the construction and ensures that the air passes through the filter in order to have all the impurities retained.

Convenience features

Using it is very easy since it doesn’t come with a variety of features, limiting the operating to filtering the air on numerous speeds. There are no additional options like a standby mode or an auto mode and all you have to do is rotate the knob to the desired speed. Additional convenience features are:

  • Intelli-Check electronic filter indicator announces when routine filter replacement is due
  • Choose from 3 speeds to customize the air purifying process depending on room size and the level that feels most comfortable for you
  • Having a changeable filter makes it more cumbersome than other models that come with a permanent filter

Warranty and support

It comes with a 5-year limited warranty that offers peace of mind by assuring you that your device will be repaired or replaced free of charge. This filter can be vacuum from time to time and it’s recommended that you change it once every 3 years. Moreover, the manufacturer provides customer support via email and phone and a wide range of filters and accessories at the best prices.
