Proscenic A8 Review Wifi Connected 50W Air Purifier With Air Quality Sensor

Tuesday, October 20, 2020

Air purifiers are fundamentally simple machines that consist of a fan that draws air through a filter to remove particles in the air. The filter component is, probably, the most important, followed by a "close second" air pollutant sensor, which allows the air purifier to monitor the air quality, just like you can with an indoor air quality monitor. 
Both air purifiers and indoor air quality monitors serve a useful purpose since most air purifiers aren't able to monitor carbon monoxide, radon and particulate matter levels. If you are forced to pick one or the other because of your budget, your best bet is getting an air purifier and cut to the chase since it's likely you will need one anyways, after monitoring the indoor air with an air quality monitor.

When choosing an air purifier, you want to keep in mind functional features and size since an air purifier that is too small for the job will take much longer to clean up the air. The Proscenic A8 is a good choice of air purifier because of its 220 cubic meters per hour (m3/h) airflow rate, which means the Proscenic A8 air purifier can circulate room air over 3 times per hour. Proscenic states the A8 purifier can service a room up to 430 ft² (square meters) or 40 m² (square feet).
The best way to calculate whether the A8 purifier will be suitable for your needs is by using the following airflow rate formula, which consists of multiplying the room dimensions by ten. For example, if your room is 3 meters wide, 3 meters long and 3 meters high, the calculation will be as follows (3x3x3) x 10 = 270, which translates to 270m3/h.
The Proscenic A8 air purifier uses a H13 filter, which isn't just a high-efficiency particulate air (HEPA) filter. It also integrates a pre-filter layer, a nano filter layer and an activated carbon filter layer, all of which contribute to improving the air quality. A HEPA filter alone can only remove dust and allergens (i.e. mold), while a carbon filter can filter out cigarette smoke, fumes and other chemicals.
A replacement H13 filter can be bought from amazon, although you could potentially use a third-party alternative if you can find a cylindrical HEPA air filter that fits. The Proscenic H13 air filter measures 18cm tall and has a 9cm diameter. Weighs 222 grams.The user guide states the Proscenic H13 air filter is rated for 2000 hours of operation, while Proscenic also recommends replacing the filter every 3-6 months, which seems a little confusing since the 2000 hour rating actually translates to 84 days. If you were to use the Proscenic A8 air purifier for 1 hour each day, the filter would technically last 2 months and a half (84 days). 
If you were to run the Proscenic A8 air purifier for 3 hours every day, the lifespan of the filter would technically be 28 days. The likely reason for the A8 air purifier 2000-hour rating is because a regular HEPA air filter can last up to 12 months, whereas a pre-filter and carbon filter have to be replaced between 3 and 6 months. 
This means, the Proscenic A8 HEPA filter layer will actually outlast the carbon and pre-filter layers. The problem is you cannot remove the filter layers because they come glued in one piece; hence they cannot be taken apart, which would be great if you could to make the Proscenic A8 running costs a little more efficient.
The Proscenic A8 (H13) filter is capable of filtering lint, pollen, mold, dust-mites, lead dust, pet dander, cooking smells, bacteria and apparently viruses, although it doesn't list which viruses. The Proscenic A8 (H13) filter can only pick up particles that are 0.3 μm (microns) in diameter or larger. Coronaviruses including C O V I D - 19  range from 0.06μm to 0.2μm in size; hence the Proscenic A8 air purifier and any other HEPA air purifiers are not capable of filtering corona viruses. You can read more about this on this article from the National Center for Biotechnology Information (NCBI).
The Proscenic A8 air purifier can be controlled remotely from a Wifi-enabled device; hence you can control the A8 air purifier from a smartphone, which is handy. You have to download the ProscenicHome mobile app (available on Google Play and App Store), which requires signing up for an account. This can be done by using your email or phone number.
If you already own other Proscenic products, you won't need to sign up again so, you can simply login and add the Proscenic A8 air purifier to the app. There is no auto scan feature; hence you have to manually add the Proscenic A8 air purifier from the "Healthy Life" tab and follow the prompts, which clearly guide you through the setup process. 
Once setup is complete, you are presented with the main interface of the application, which has a simple layout with a large image of the A8 purifier and the menu buttons for controlling the air purifier.
The Proscenic A8 app control functions include power on/power off, fan speed, timer, sleep mode, child lock and lights off, which lets you turn off the air purifier's light. The timer can be set from 1 to 10 hours; hence you can have the Proscenic A8 air purifier running for 10 hours before shutting off. You can also schedule day of the week and time you want the air purifier to turn on and turn off. You can also connect to a voice control assistant such as Alexa or Google Home/
The app also features a filter usage time stat that you can view to check the condition of the filter. The filter stat shows remaining runtime (up to 2000 hours) and remaining usage rate (0% to 100%). The A8 air purifier automatically alerts you when the filter needs replacing.
The top section of the Proscenic A8 air purifier features a fan grill cover with aerodynamic fins and a circular control panel with touch sensitive buttons, which make a really loud piercing beep when activated. There is no loud beep when the Proscenic A8 air purifier is in sleep mode, which also dims the control panel light icons. You can manually enable the Timer function from the unit too but, it is limited to only four options: 2 hours, 4 hours, 6 hours or no timer.
The A8 air purifier control panel has a 9.5cm diameter, while the dimensions of the Proscenic A8 air purifier are 41cm tall and a 24cm diameter. Total weight of the unit is 1kg (without the air filter). The Proscenic A8 air purifier comes apart in three main pieces: the housing, filter and bottom lid, which has a twist lock closure. The bottom area of the purifier (back and front) has large hole perforations for air to enter.
There is an led light along the bottom perimeter of the Proscenic A8 that can flash various colors (Green=excellent, yellow=good and red=poor) to indicate the current quality of air. The Proscenic A8 air purifier has four modes: Sleep Mode, Mode 1 (low speed), Mode 2 (high speed) and Auto Mode, which you will find yourself using the most because Auto mode automatically adjusts the filtration speed between low and high, according to the quality of the air. 
Sleep mode is the lowest speed; hence the quietest mode which generates approx. 20dB of noise (whisper noise). Mode 2 is the highest fan speed, which generates around 55dB - about as loud as a regular home conversation (approx. 60dB)
Because of its large size and multi-layered filtration system, the Proscenic A8 does a superb job at cleaning the air from impurities. Ionizers (ionic air purifiers) do a similar job, although not quite as effective as using a physical filtration medium. That said, ionizers use electrically charged ions to remove impurities without the need of filters, making an ionic air purifier more economical.
Being an air filter, the Proscenic A8 requires dusting out periodically to maintain performance. The user guide states the built-in air quality sensor has to be cleaned out every 3 months. However, there is no instructions on where and how to access the air quality sensor, although it is likely to be near the fan motor mechanism. In which case, you could probably use a compressed air can to blow out the dust. You can buy the Proscenic A8 on amazon. Check out the review of the Proscenic 808C humidifier.
