Mini/Mini+ Replacement PECO Filter

All Molekule air purifiers are equipped with advanced filtration systems that combine Molekule’s patented PECO technology with a True HEPA filter, achieving a 99.97% particle-capture efficiency rate. This is further enhanced by a layer of carbon filtration that reduces odours and toxic gases. The unique PECO technology actively destroys pollutants that traditional HEPA filters might miss. When organic particles interact with the specially coated fibres in the filter, LED light triggers the production of hydroxyl radicals, which oxidise and break down organic matter at a molecular level. This process inactivates harmful pathogens and transforms volatile organic compounds (VOCs), allergens like dust mites, airborne mould spores, pet dander, pollen, and viruses (such as H1N1 and SARS-CoV-2) into harmless gases like carbon dioxide and water vapour. This comprehensive filtration approach is particularly beneficial for individuals with asthma or allergies. As FDA-cleared and CARB-certified devices, Molekule air purifiers guarantee exceptional quality and performance for creating a healthier indoor environment.

Molekule was founded in 2014 to address the harmful effects of indoor air pollution through advanced science. Aeroclean, established a year later, set out to make everyday environments safer by improving the air we breathe. In 2023, the two companies merged as MKUL, Inc., combining their expertise to deliver innovative air purification solutions. Their FDA-cleared technology uses HEPA, carbon, and light activation to capture and destroy airborne pollutants. Together, they remain committed to providing clean air solutions for businesses, homes, and any space where you and your loved ones live and breathe.

Over time, large particles can build up and the PECO layer degrades over time as the filter in your purifier fights organic pollutants. It is recommend to replace the filter in the Molekule Air Mini and Mini+ every 6 months when the Filter Status is pulsing orange or red on the top of the device or if the filter status in the mobile app says it needs replacing.

With the base on a steady surface, twist the device shell counterclockwise and lift it to open.

Lift the used PECO-Filter off the device base and discard.

Remove the new PECO-Filter from the packaging and place it onto the base with the small hole face down, as indicated on PECO-Filter.

Place the device shell back onto the base and twist it clockwise to click it into place. Good work.
