Meet the benchmark and beat it.
Starting with verified third-party HEPA filtration, we test carbon and PECO to fine tune purification that captures and destroys pollutants.
Patent-pending technology
Third-party HEPA certified
CARB certified
FSA/HSA eligible
Two new air purifiers. Three new colorways.
The next generation of clean air technology is here.
Scientifically better air
PECO-HEPA Advanced
Captures and destroys more pollutants than HEPA-only purifiers.
Adsorption
70% more activated carbon adsorbs gases, VOCs and odors.
Capture
Verified True H14 HEPA filtration captures 99.97% of particles, down to 0.3µm.
Destroy
PECO technology destroys VOCs, viruses and more that HEPA alone can’t handle.
Only Molekule uses photo electrochemical oxidation (PECO) to break down the smallest pollutants at the molecular level.
ALWAYS INNOVATING
Scientifically better, every day.
As air pollution evolves, so do we. We're constantly innovating in filters and app features, so air purification is smarter for everyone.
Smarter features for real life.
Beyond just filtration, we build air purifiers that fit into your life. Colors, smart modes, and more help you elevate your entire environment.
PECO TECHNOLOGY
Destroy what you can’t see.
You can see dust on a shelf—but many pollutants are much harder to spot. PECOAir purifiers sense, detect, and clean the air you’re breathing.
Pollen grains are large and they come inside on clothes, shoes and open windows. They're among the easiest particles for HEPA-grade media to capture, reducing your exposure and allergy triggers.
RELATIVE WIDTHS:
Pollen 10µm
Human hair 70µm
Dander is a particle, 0.5 to 10 microns, and it goes everywhere the pet does. HEPA filtration captures it, while PECO is proven to destroy fel D1, the protein that causes allergic symptoms.
RELATIVE WIDTHS:
Pet dander 8µm
Grain of salt 40µm
Spores drift in the air long before they grow on a wall. HEPA filtration captures large particles while PECO breaks down mycotoxins and other byproducts of mold.
RELATIVE WIDTHS:
Mold spore 5µm
White blood cell 25µm
Airborne bacteria ride on everything from a cough to a shaken rug. HEPA captures these particles, reducing what’s present in your air.
RELATIVE WIDTHS:
Bacteria 2µm
Red blood cell 8µm
PM2.5 is the fine dust from cooking, traffic and wildfire smoke, small enough to stay airborne for hours. HEPA filtration captures 99.97% of particles at 0.3 microns, reducing them in your air.
RELATIVE WIDTHS:
PM2.5 2.5µm
Fine beach sand 90µm
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 molecular level rather than leaving it on a filter.
RELATIVE WIDTHS:
Virion 0.3µm
Respiratory droplets 5–10µm
Proven in the lab
PECOAir+ captures and destroys more pollutants than HEPA-only purifiers.

Testing done in 2026 per AHAM AC-1 in a 28.5m³ chamber by Intertek; an independent, third-party, nationally recognized testing laboratory.
In the lab
99%
reduced in 22 minutes
Smoke is a toxic cocktail of gases, particulate matter, and materials burned by fire.
Effects
Respiratory irritation; eye irritation; headaches; reduced lung function; exacerbation of existing conditions; chest pain; fatigue; stroke
Pollen
2.5–200µm (25µm on average)
Testing done in 2026 per AHAM AC-1 in a 28.5m³ chamber by Intertek; an independent, third-party, nationally recognized testing laboratory.
In the lab
98%
