Product Details
PECOAir+ is more than an air purifier. It is a complete environmental monitor for spaces up to 875 sq ft. Equipped with an advanced sensor suite that includes more sensors than PECOAir or any previous Molekule purifiers, it features particulate matter, humidity, temperature, dual TVOC sensors and True CO2 monitoring, giving you a complete understanding of the air you’re breathing.
Those readings feed the Molekule app's Environmental Intelligence, which shows how favorable the room's conditions are for viruses or mold. PECO-HEPA Advanced filters capture particulate matter and destroy bacteria, viruses, mold, and VOCs at the molecular level.
Designed with multiple smart modes, PECOAir+ features two Auto Protect functions that automatically adjust to air conditions, Sleep mode that lowers fan speeds and dims light; and Deep Clean mode that powers the fan to its highest setting for clearing pollutant spikes quickly. Built with a brushless Nidec fan system, PECOAir+ is the quietest Molekule air purifier to date.

Features
Know your air like never before
PECOAir+ is more than just an air purifier—it contains cutting-edge sensors that monitor your environment to give you clarity, comfort, and cleaner air.
-
-
Choose your mode
Auto Protect adjusts to pollutant spikes. Sleep mode dims lights and lowers the fan. Deep Clean combats air quality events.
-
Sleep soundly
A brushless Nidec motor powers the NearSilent™ fan system for continuous air purification at a fraction of the noise of previous Molekule purifiers.
-
Environmental Intelligence
Only PECOAir+ connects to the Molekule app’s Environmental Intelligence, measuring PM2.5, relative humidity, and CO2 so you when a room's conditions favor mold growth or viral transmission.
Next-generation filtration
PECO-HEPA Advanced is the result of 30 years of research and development dedicated to creating cleaner indoor air.
-
Activated carbon
High-grade activated carbon adsorbs VOCs and odors that are byproducts from cooking, cleaning chemicals, and paint.
-
Third-party certified HEPA filtration
99.97% HEPA Efficiency at 0.1-0.3 microns, reducing pollen, pet dander, and particulate matter in your home. Measured to capture of ultra-fine particles as small as 2.5 nanometers.
-
PECO technology
Photo electrochemical oxidation (PECO)—a proprietary, light-activated nanocatalyst, destroys VOCs, viral matter and bacteria too small for conventional HEPA filters to affect.

Activated Carbon
High-grade activated carbon adsorbs VOCs and odors that are byproducts from cooking, cleaning chemicals, and paint.
-
Reduces VOCs
Reduces gases and vapors from VOCs like toluene and formaldehyde through a combination of adsorption and destruction of molecular bonds.
-
Destroys Microbes
HEPA filtration captures components that carry microbes like viruses, bacteria, and mold. PECO destroys microbes at a molecular level.

The PECOAir+ difference
More air with less noise
An environmental health monitor
NearSilent™ fan system
10dBA quieter than Air Pro at high speed.
Viral & Mold conditions
Closely monitor conditions that could lead to mold growth or viral transmission within 875 sq ft.
Beyond pollutants
True CO2, temperature, and relative humidity sensors let you gauge how your air is affecting your comfort.
WHAT’S IN YOUR AIR?
Capture and destroy what you can’t see
Pollen
Pollen is one of the largest particles in your air, 10 to 100 microns. True 99.97% H14 HEPA filtration captures particles down to 0.3 microns, reducing pollen in your air.
Pet Dander
Pet dander measures 0.5 to 10 microns. True 99.97% H14 HEPA filtration captures particles down to 0.3 microns, reducing pet dander in your air.
Mold
Mold spores measure 2 to 10 microns. HEPA filtration captures them, and PECO (photo electrochemical oxidation) is proven to destroy mold rather than leaving it on a filter.
Bacteria
Bacteria measure 0.5 to 5 microns. HEPA filtration captures them, and PECO (photo electrochemical oxidation) is proven to destroy bacteria rather than leaving them on a filter.
Particulate Matter
Particulate matter measures 0.1 to 2.5 microns. True 99.97% H14 HEPA filtration captures particles down to 0.3 microns, reducing particulate matter in your air.
Viruses
Viruses like influenza, COVID-19, and RSV travel on droplets and dust. Some are smaller than what filters can trap. HEPA filtration captures what carries viral matter, and PECO destroys it at the molecular level rather than leaving it on a filter.

Proven in the lab
PECOAir+ captures and destroys more pollutants than HEPA-only purifiers.

Acetylacetone
Tested per GBT18801-2022 standard in a 30m³ chamber.
In the lab
82%
reduced in 60 minutes
Acetylacetone is a solvent used in manufacturing that off-gases VOCs into the air at room temperature.
Common sources
Off-gassing from paints, wood stains, adhesives, and electronics
Volatile organic compounds
VOCs: Gases, chemicals, and toxins in your air Not everything can be captured: VOCs.
Volatile organic compounds are gases, not particles. They come off fresh paint, new furniture, adhesives, cleaning products and nail polish, and at about a nanometer across they pass through a HEPA filter untouched.
PECOAir+ treats VOCs in two stages:
- 01High grade activated carbon adsorbs gases on their way in.
- 02PECO destroys the remaining gases as they pass through, breaking molecular bonds through oxidation.
