Filter Types

Air purifiers consist of different types of filters, each designed to target specific pollutants.

The higher the CADR rating, the quicker it removes pollutants.

Its measured in cubic feet per minute (CFM).

We especially loved that the vents are adjustable so you might blast clean air where you need it most.

It successfully neutralized odors and removed the clay dust our cats kicked up from their litter box.

A clear, plastic cover on top adds to its modern look.

Most of the time, we kept it on auto and let it do its thing.

The touchscreens delayed reaction is a little frustrating.

We noticed that we coughed less at night with The Orsani Mod + HEPA Air Purifier around.

The touchscreen interface was easy to use albeit a little laggy.

Once we got past that, the filter itself slid in and out with no problem.
