The Proscenic Air Purifier A9 isn’t the sexiest gadget I’ve ever reviewed, but sometimes you don’t need sexy, you just need it to work.

There are certain gadgets you interact with every day.

I interact with my Amazon Alexa a dozen times per day.

There are other gadgets you set up once and let them do their thing.

Your Wi-Fi router is an example of a device you want to just set up and let it do its job.

The Proscenic A9 ($219) falls in the latter camp.

What is it?

The A9 is a very good-looking air purifier designed to clean the air in a space up to 968 square feet.

The purifier is basically a fan in an enclosure that draws air in through holes in the sides, through a filter and out the top. It also has some advanced circuitry to continually test the air and display the air quality.

It ships with an H113 True HEPA filter that is designed to last 6 to 12 months.

The HEPA filter has four stages of filtration:

  • A preliminary filter for hair, dander and large particles.
  • The Sliver Ion Sterilization filter to kill bacteria.
  • An H13 High-Efficiency HEPA filter that turns residual ozone into fresh air.
  • A Granular Activated Carbon filter to collect dust and other harmful substances.

The A9 has a display that shows the PM 2.5 particle level in the air. According to the EPA, PM 2.5 describes fine inhalable particles, with diameters that are generally 2.5 micrometers and smaller.

The display also shows a colored bar to indicate the quality level:

  • Green means the level is from 0 to 50, considered good quality.
  • Yellow means the level is from 51 to 100, or moderate quality.
  • Orange means the level is from 101 to 150, which is unhealthy quality for sensitive people.
  • Red means the level is over 150 and the quality is unhealthy for everyone.

When I powered on the A9, the reading was eight. After a few minutes, it settled between one and three.

Setup

The A9 is almost ready to use when you take the unit out of the box, but the filter ships inside the unit in a plastic bag that needs to be removed. You pull open the filter cover (it uses magnets) and take the filter out of its plastic bag and put it right back in.

The cylindrical filter is closed on one end and open on the other. The closed end goes toward the floor.

Then you just plug it in and press the power button.

The A9 will start up in Automatic mode, which means it will read the particulate level in your room and change the fan speed to what it thinks is best to get the level down to a good range.

The fan has four speeds, but honestly, I don’t see a need to use any mode other than automatic.

You might need to change the fan speeds if your home is very dusty or smoky.

There is a row of buttons above the display along the top edge that control power, fan speed/auto mode, a timer for up to eight hours and a child lock switch.

App

You can download the free Proscenic app and connect the A9 to Wi-Fi.

You’ll have to set up a free account in the Proscenic app.

Once configured, you can use the app to control the A9 when you’re away from home.

If you have Alexa devices in your home, you can use the app to link the purifier to Alexa for voice control.

I mentioned earlier that my first inclination was to leave the A9 on automatic mode and leave it alone, but in the app I found a way to schedule a mode called sleep, which slows the motor to a whisper and turns off the display. You can set sleep to turn on or off daily as you like.

How well does it work?

I have to say, the air quality in my bedroom is good, but I already had a purifier in there running constantly.

I turned it off to test the A9.

My purifier does not have a display to show me the air quality, although it does have an app that shows me whether the air quality is good.

I like the A9′s large display of real-time air quality, but it is bright. You’ll want to turn the display off or turn on sleep mode if you have it in your bedroom.

The fan is very quiet at level 1, with increasing noise through levels 2 through 4.

The sound at level 4 is a bit too loud for sleeping unless you really like white noise.

Since I’ve turned on the A9, the PM 2.5 reading in my bedroom has stayed under 5 and spends most of the time at 1 or 2.

Conclusion

I certainly noticed the air quality difference by putting an air purifier in my home. Scientists say it’s unlikely that air purifiers can help with coronaviruses because the particles are so small, but the pandemic has still raised our awareness about the quality of the air in our homes.

The Proscenic A9 is a stylish and very quiet model that filters your home’s air in four ways.

People who suffer from allergies already know the benefits of air filtration, and I can’t help but think any home can benefit from an air purifier, especially if you have pets or a smoker in the house.

In our house, we suffer from allergies, and when we have a purifier running, either ours or the A9, we can definitely tell the difference in our heads and lungs.

Just be sure to change the filter regularly.

Pros: Excellent filtration, easy to set up and use, app for remote control.

Cons: Replacement filters are expensive.

Bottom line: You’ll feel the difference in your lungs. The Proscenic A9 is a powerful air purifier.
