Filter System

Filtration Technology

The Instant uses a multi-stage system anchored by an H13 HEPA filter that captures 99.97% of particles at 0.3 microns , that includes dust, pollen, mold spores, and fine pet dander. An activated carbon filter layer absorbs smoke, cooking odors, and VOCs, while the built-in Plasma Ion Technology releases ions that attach to airborne impurities and neutralize them.

This hybrid approach of physical filtration plus ionization gives it broader coverage against both particulate and gaseous pollutants than HEPA-only competitors in this category.

CADR & Sound

Noise & Performance

At its lowest setting, the unit operates at a remarkably quiet 5 dB , virtually inaudible and well below the 25 dB threshold for whisper-quiet classification. It delivers 5 air changes per hour across its rated 1,940 sq ft coverage area, which is strong for a unit drawing only 50W.

Customer feedback is split on higher speed noise levels, so expect noticeably more fan noise when the auto mode ramps up in response to detected impurities.
