Air purifier TOSHIBA CAF-Z123XPL (W) with 2 x 5-layer filters. The main filter collects pet hair and coarse dust. The PET filter removes atmospheric aerosols with a diameter of no more than 2.5 µm, and the carbon filter adsorbs formaldehyde, VOCs, and other pollutants. The next layers include a HEPA filter, which guarantees a dual effect of filtration and adsorption - it effectively removes PM0.1 particles, bacteria, and allergens. The final layer of the PET filter extends the lifespan of the entire filter, allowing it to last longer.
