Molekule Air Purifiers: Best Innovative Technology

Price: $919.

Molekule Air Purifiers are distinctive for their PECO technology, which decomposes airborne particles and pollutants with UV-based reaction unlike the activated carbon filters that merely entrap air contaminants. Nevertheless, both experts and customers have given different reviews on its usefulness to improve indoor air quality. It was not as effective in getting rid of particulate pollution when compared with the Levoit Core 300’s HEPA filter, particularly smoke levels were found difficult to control by Molekules.

On the downside is a high cost – $919. Followed by an additional replacement filter charge at every 6 months’ end worth $90 makes it pricier than some other best available purifying systems in the market. Even though its price tag could make you hesitate, if having cleaner indoor air holds paramount importance, then Molekule offers powerful products owing to advanced technology.

Pros and Cons

Price: $919.


  • Proprietary PECO filtration technology eradicates pollutants
