Replacement  Air Filter For Therapure Envion TPP440 TPP540 TPP640 Air Purifier Filter

HEPA cartridge technology with two layers of filtration:

HEPA-Type Cartridge Layer: this layer of the cartridge utilizes HEPA (High Efficiency Particulate Air) like technology to capture smaller particles such as bacteria, viruses, pollen and dust. While its filtration efficiency is slightly lower than a true HEPA cartridge, it still provides decent air purification and has a long lifespan.

UVC Lamp Cartridge Layer: This layer of the cartridge has a built-in ultraviolet (UVC) lamp that destroys bacteria, viruses, and other harmful substances in the air.The UVC lamp destroys the DNA structure of these microorganisms and prevents them from reproducing and spreading, thus purifying the air effectively.

The life span of the cartridge depends on the usage environment and air quality. It is recommended to replace the cartridge every 3 to 6 months depending on the actual situation to ensure continuous and effective air purification. To replace the cartridge, simply open the back cover or top cover of the purifier, remove the old cartridge and place the new cartridge in the appropriate position. Regular cleaning and maintenance of the purifier is recommended to maintain its optimal performance.
