In-depth Review of Bissell Air400 Purifier:
Here are the top features of the Bissell Air400.
True HEPA Filter with Pre-filter
Bissell Air400 comes with a large True HEPA filter protected by a fabric pre-filter attached by velcro strips. It captures larger airborne pollutants such as hair, pet fur, lint and also extends the lifespan of the main HEPA filter.
The pre-filter is detachable and can be washed with water.
Ideally, a True HEPA filter can effectively remove 99.97% of all airborne particles that are 0.3 microns and larger. Household dust, pollen, mold spores, smoke residue fall under this category. So, if you run it all the time, it will filter all the airborne particles from your room.
This filter can be used for up to six months. The purifier also has an indicator that will tell you when to replace it.
Honeycomb Carbon Filter
Granular activated carbon is a good adsorbent material to control odors. Bissell Air400 comes with a 1-inch thick activated carbon filter to adsorb household odors and VOCs. The honeycomb-structured filter has almost 50,000 activated carbon pellets, which is about 465 grams.
The amount of carbon is sufficient enough to neutralize light to medium household odors.
Room Coverage and CADR
Bissell Air400 is the highest room coverage air purifier from Bissell. The Smoke CADR for this model is 313 cfm, which is suitable for medium to large rooms. With this CADR rating, the purifier can clean up to 470 square feet of rooms five times an hour.
With powerful filtration and the CADR rating, the Bissell Air400 is suitable for cleaning heavy smoke and medium odors.
Aesthetics
Bissell Air400 comes in a metallic grey color, which they called titanium grey. On the front, it has a beautiful display to show real-time air quality status. It comes with a back-to-top air delivery design. You can easily move it using the carry handle.
Particle (PM2.5) Sensor
Bissell Air400 has a built-in particle sensor that counts PM2.5 (2.5 microns in diameter) particles in the air. In auto mode, it adjusts the fan speed automatically based on the sensor reading. The purifier also displays the PM2.5 counts with a colored indicator.
To get accurate readings, you have to clean the particle sensor lens twice a month.
Night Mode
Another useful function is the light sensor. All the onboard lights turn off, and the colored AQI indicator dims when the room goes dark. However, it doesn’t change the fan speeds if it is not set to automatic mode.
