The Best Air Purifier on the Market: Molekule is a premium air purifier designed for large rooms up to 600 sq. ft. Photo Electrochemical Oxidation (PECO) is a new way of filtering air that goes beyond HEPA filters. It captures and destroys airborne pollutants like allergens, bacteria, mold, viruses, and volatile organic compounds (VOCs). The Molekule Air Purifier has received mixed reviews, with some praising its effectiveness and design, while others question its performance compared to other air purifiers. In this article, we will explore the features, performance, and value of the Molekule Air Purifier to help you decide if it’s the right choice for your needs.

Features and Design

The Molekule Air Purifier boasts a sleek, modern design with an anodized aluminum body and a vegan leather handle for easy portability. It Features a touch-screen interface and can be controlled remotely using a smartphone app. The device offers three fan speeds and an Auto Protect mode that adjusts fan speed based on real-time air quality.

The main selling point of the Molekule Air Purifier is its PECO filtration technology, which combines the power of HEPA’s 99.97% small particle capture efficiency with PECO’s ability to destroy contaminants. This technology is said to be more effective than traditional HEPA filters, as it can destroy particles 1,000 times smaller than the standard set for HEPA filters.


The Molekule Air Purifier has been tested and shown to reduce levels of different airborne contaminants, including dust, mold, bacteria, and viruses. However, some independent tests and reviews have questioned its performance compared to other air purifiers. For example, Consumer Reports ranked Molekule 45th out of 48 air purification devices, and Wirecutter called it the “worst purifier we’ve ever tested”.

Despite these mixed reviews, many users have reported improvements in air quality and allergy symptoms after using the Molekule Air Purifier. It’s worth noting that individual experiences may vary, and the effectiveness of the device may depend on factors such as room size, pollutant levels, and usage habits.


The Molekule Air Purifier is priced higher than many other air purifiers on the market, which may be a concern for some potential buyers. However, its unique PECO filtration technology, sleek design, and smart Features may justify the higher price for those who value these aspects. Additionally, the device comes with a 2-year limited warranty and a 30-day in-home trial period with free return shipping, offering some peace of mind for potential buyers.


The Molekule Air Purifier offers a unique approach to air purification with its PECO filtration technology and modern design. While its performance has been questioned in some independent tests, many users have reported improvements in air quality and allergy symptoms. If you’re looking for a premium air purifier with innovative technology and a sleek design, the Molekule Air Purifier may be worth considering. However, it’s essential to weigh the higher price against your specific needs and preferences before making a decision.


How does Molekule’s air purifier work differently than other air purifiers on the market?

Molekule uses PECO (Photo Electrochemical Oxidation) technology, which is a patented system that destroys pollutants at the molecular level. This is unlike other filters that only capture pollutants and don’t remove them from the air. PECO technology works by creating an electrochemical reaction that breaks down pollutants into harmless molecules like water and carbon dioxide.

Is Molekule’s air purifier effective in removing viruses from the air?

Yes, Molekule’s air purifier has been third-party tested and proven to destroy airborne viruses, including H1N1 flu virus, MS2 bacteriophage virus, and others. It also eliminates VOCs (volatile organic compounds), allergens, mold spores, bacteria and other harmful particles.

How often do I need to replace Molekule’s pre-filter or PECO filter?

The pre-filter needs to be replaced every three months while the PECO filter should be changed every six months or when it reaches its maximum capacity of 12 months of use based on eight hours of daily usage. The app will notify users when it’s time for replacement so you can stay healthy with clean indoor purified air all year round!
