This technology is safe and nontoxic to anyone in your environment, and without the worry of re-admittance into your environment. Lastly, the PECO technology is the technology used in the Molekule air purification system.
What are the two disadvantages of HEPA filters?
Cons: HEPA filters however cannot trap other pollutants such as gases, fumes, chemicals and odors. Can be costly when replacing filters. Replacing filters can become costly depending how many times you change the filter. Shape and compactness of the unit depends on what type of air purifier you have.
What is the highest HEPA filter rating?
H13-H14 HEPA are within the highest tier of HEPA air filtration and are considered medical-grade. “A HEPA grade of H13 can remove 99.95% of all particles in the air measuring 0.2 microns in diameter, while a HEPA grade H14 removes 99.995%,” says Nagl.
