Dreo Macro Max S
Provides Quality
& Affordable Air
Purification
By Nicholas Boever
WITH INTEREST and
demand in air quality having
drastically evolved over a few
short years, the capabilities
of air purifiers have grown
in kind, especially as smart
home devices rise in popularity
and integration with
wellness products widens.
This has led to companies
pushing to create high-performance,
standalone
devices that can easily be
integrated into mainstream
smart home systems (i.e.
Amazon Alexa or Google
Home), and that's the backdrop
for my receiving the
Dreo Macro Max S Smart
True HEPA Air Purifier.
The Macro Max S
incorporates three-stage
filtration and a H13 True
HEPA Electrostatic filter.
Features & Setup
According to Dreo, the
$219 Macro Max S uses a
three-stage active filtration
alongside a H13 True
HEPA Electrostatic filter
- the " electrostatic " part
just makes it so dust and
other, smaller particles cling
together, becoming larger
so the filter can catch them.
With HEPA still being the
gold standard in air filtration,
the Macro Max S has a
strong base.
Using this setup, Dreo
claims the Macro Max S can
process a 423-square-foot
room in about 12.5 minutes
(smaller rooms require
shorter times).
Built into this air purifier
is also a highly advanced
air quality monitor that
measures particulate matter
(PM2.5). While limited
in comparison to what
encompasses a true read of
air quality, it does address
one of the biggest culprits of

The Dreo Macro Max S operates at ultra-quiet 24dB.
poor air quality in a home.
The device uses the monitor
to regulate the fan power
on Auto Mode. Baseline, the
purifier is said to operate at
24dB. For reference, an average
conversation is about
60dB. Dreo also states that
in Auto Mode, the average
cost of running the purifier
comes to about $4 per
month at a rate of 13.7 cents
per kilowatt hour (kWh).
Via the app, users can set
timers for the Macro Max S,
view filter life (though this
can also be viewed on the
device itself) and integrate
with Alexa and Google
Home. Device connections
occur over Wi-Fi 2.4G, and
once connected, the device
can be monitored and
controlled from everywhere
there is Wi-Fi.
The app also includes
air quality history reports
that update about every 15
minutes or so and operates
in 15-minute intervals with
histories lasting up to 30
days in the app.
The setup was simple.
From unboxing to getting
everything up and running,
the process took less than
5 minutes. All that was
required was to download
the Dreo app (available on
Android/iOS) to link the
device to the Wi-Fi network
and integrate with Alexa
and Google Home. The only
other hurdle is removing the
plastic covering on the filter.
Users can then control
fan speed and set display
options: PM2.5 levels or a
vaguer air quality rating that
operates on a percentage
system with 100% being the
best quality air. For both
readings, the display will also
change the colors of an LED
tower based on air quality,
moving from Blue (Best), to
