In-depth Review on Bissell air400:

True HEPA Filtration: Bissell air400 comes with a large true HEPA filter. A thin sponge-like pre-filter attached to the HEPA filter. It captures more significant pollutants like hair, pet fur, lint and also extends the lifespan of the primary HEPA filter.

The pre-filter is washable with water.

Theoretically, the HEPA filter is capable of capturing particles that are sized down to 0.3 microns with 99.97% efficiency. So, it will remove pollen, household dust, mold spores, pet dander, and smoke particles from the air. Bissell suggests changing the filter every six months. Though the filter life depends on your usage and the air quality, however, the air purifier has filter life indicators for both HEPA and Carbon filter.

Honeycomb Carbon Filter: Bissell air 400 featured a large and 1-inch thick activated carbon filter to absorb household odors and VOCs. The honeycomb-structured filter filled with 50,000 carbon pellets, which weigh nearly 465 grams. The amount of carbon substance is sufficient to remove household odors efficiently.

Room Coverage and CADR: Bissell advertised the unit is capable of cleaning a room of 400 square feet with 3 air changes per hour. From this data we can calculate the airflow rate in cfm (cubic feet minute) with the formula: CADR = (3 ACH x 400 sq ft x 8 ft ceiling)/60 minute = 160 cfm.

The airflow rate of 160 CFM is pretty good enough for a medium-sized room. Check out our room size recommendations to select Bissell air400.

Noise Level: On the highest fan speed, its noise level is about 64 dB, which is very loud, but on the low fan speed, it drops to 30 dB that is very quiet. The refrigerator sound level is around 40 dB. So, for overnight running, it won’t bother you by noise. It uses a brushless DC motor, and they claim 20000 hrs of runtime.

Particle Sensor (PM2.5): Bissell air 400 has a built-in particle sensor and displays the air quality with a color indicator and also shows PM 2.5 count. The automatic mode, which they called CirQulate system, runs based on the particle sensor.

In auto mode, it adjusts the fan speed depending on the sensor value like every other air purifier. You have to clean the sensor every two weeks to run it smoothly.

Control: Its super easy to control, has three modes of operation: max, auto, and silent. Also, you can set the fan speed manually: low, mid, and high. It features a preset timer of 1, 4, and 8 hours.

Night Mode: The white lights on the control panel and the front display turned off based on the ambient light condition. The color indicator goes dim. However, it doesn’t change the mode of operation; you have to adjust it manually.

Certifications, Warranty: AHAM does not verify the CADR. However, it is EnergyStar certified. Bissell air400 comes with a 2-year limited warranty.
