There’s absolutely no reason why any home, apartment, or office building should not have an air purifier. With so many vehicles passing by and a high number of construction projects taking place nearly everywhere, it’s not uncommon to find indoor air quality dropping to near-suffocating levels.

But of course, not any old air purifier can do the trick – the toughest jobs require the toughest air purifier, and the BISSELL 2768A air320 might be able to do the trick. So let’s take a quick look at what this BISSELL-made air purifier is packing to determine whether it’s worth the investment.

3-Stage Filtration

Standard air purifiers come with more than one line of defense to tackle nasty airborne particles from entering our lungs and wreaking havoc. In general, the more filters used, the better the air purifier will be at trapping both large and microscopic particles. The air320 uses a 3-stage filtration system consisting of a fabric pre-filter, an activated carbon filter, and a high-efficiency filter (not True HEPA).

The fabric pre-filter works just as any other pre-filter on the market; it traps the large, visible particles from clogging the high-efficiency filter located behind it. The air320’s pre-filter also doubles as a front cover which, in our opinion, is a nice touch that adds a bit of white to an otherwise pure-black panel.

The activated carbon filter serves to snatch odor particles and VOCs from the air. The freshness of indoor air is only as good as the smell, so the activated carbon filter comes is a must-have for many people.

The final line of defense is the high-efficiency filter that traps up to 99% of particles as small as 0.3 microns in size. Airborne allergens like dander, pollen, and specks of dust have a close-to-zero chance of making it past the unforgiving fine-mesh filter.

The downside of having so many filters is the different replacement times and costs. The pre-filter requires changing every 4 to 6 months, the activated carbon filter every 3 months, and the high-efficiency filter every 2 months. Maintaining flawless airflow in and out of the device can be a pain, but it’s definitely worth it to keep the machine functioning properly.

Built-in Indoor Air Quality Sensor

One thing you may have noticed is that the air320 does not have a timer function. Without it, how is it possible to just set the device up and go? The good thing is that it’s entirely possible to do so, and without the fuss of setting up inflexible timers.

The air320 comes has a built-in indoor air quality sensor that constantly monitors the air quality of a room. If the air quality falls to a certain threshold, the air320 will automatically kick-start to life to flush the air of pesky particles. No timer, no problem!

Automated Fan Speed Adjustment

But that’s not all the air quality sensor can do. The sensor works together with the device’s fan system to determine which fan speed is most appropriate. For unbelievable dirty air, the air320 will select high-speed fan mode to get rid of dust in a timely and effective manner. For less-dirty air, the air purifier will choose a more energy-efficient cleaning mode to get the job done.

1,000-square-foot Cleaning Capacity

The air320 is rated to cover rooms of up to 1,000 square feet. The average kitchen, living room, office unit, and bedroom falls within the 1,000-square-foot capacity of the air320, making it an unbelievable piece to have for a number of different rooms and settings. Since this air purifier automatically selects the appropriate fan speed, you won’t need to worry about overkill or underkill – let the air320 do the calculations and the thinking for you.

Whisper-Quiet on Sleep Mode

One of the most astounding features of the air320 is its automated sleep-mode function. When the sun has gone down, the air320 will automatically switch to quiet mode which drops its noise production to a gentle 37-db buzz. On sleep mode, the LED lights automatically turn off to provide the user with distraction-free air-purifying.

Obnoxiously Loud on High Mode

But on any mode other than sleep mode, the air320 struggles to live up to its “whisper-quiet” title. By no means is the air320 whisper-quiet. After testing this device out, we’ve noticed that the noise production level exceeds the maximum 59-db rating. In fact, on high mode, the air320’s buzzing can drown out regular conversation volume.


After taking a look at what the BISSEL 2768A air320 has to offer, we can conclude that this air purifier is indeed a remarkable tool. It works as marketed by snatching particles – both visible and invisible to the naked eye – out of the air, trapping them in its fine-mesh high-efficiency filter until the end of time.

We absolutely love the convenience that the indoor air quality sensor offers and that it selects the right speed for us, but its noise production is somewhat of a put-off. The good thing is that at nighttime, the air320 will not disrupt a peaceful sleeping environment.
