Its operating of is based on 3 stages that work together to eliminate most of the impurities found in the indoor air. During the first stage, a pre-filter containing activated charcoal captures large particles like dust and hair, as well as household odors like smoke, food, cleaning products vapors or pet odor. This pre-filter makes sure to retain larger particles before they get to the second stage, which is an HEPA filter that can retain small particles down to 0.3 microns in size. The third stage includes an ionizer that attracts particles like viruses, bacteria, chemical vapors, odors, and harmful gasses. The main concern about ionizers is that they produce ozone, which can be harmful in case it is inhaled, but with it, there is no danger of inhaling ozone as the ionized particles are quickly broken apart so you won’t have time to inhale them.

Although it measures 24 inches in height and 19 in width, it is only 10 inches deep so you can easily fit it in one side of the room and in case you want to move it, you can grab and lift it as it only weighs 15.7 pounds.

    How much noise does it produce on the highest speed setting?

    • When you set it on high, it can produce up to 60 decibels. Thus, it does not present a nuisance regardless of its operating speed. However, we do recommend you set it on low overnight if you keep it in the bedroom or nursery as the noise output is considerably lower, namely 26.6 decibels.
