The ranking of the HEPA filter is determined through the size of particulate issue it may possibly seize. The MERV score fees all filters about their system and usefulness.
While we have been not able to measure its efficiency in our testing, we are intrigued from the UV light-weight and ionization characteristics that this air purifier has. The producer claims which the UV gentle can reduce up to ninety nine.nine p.c of viruses, microbes, and mildew.
in which REL (reference exposure amount) refers back high performance liquid chromatography system to the dose at which sizeable harmful health effects will happen in the uncovered group.
five amounts, alter the admirer velocity, alter the air purifier's lights and switch on a youngster lock to stop curious Young children from unintentionally turning off the device. Adjustable Lights
Levoit Main Mini Air Purifier: Although we love this air purifier for modest spaces, it failed to stand up to your Competitiveness inside our latest round of testing.
