Compared to the other ceiling hanging air filtration systems on our list the jet is not much bigger when it comes to overall dimensions.
Floor vs ceiling air filtration.
The filter efficiency is high the airflow outstanding.
If you are building your own or if the air cleaner you are purchasing rates only the fan figure you will lose about 25 40 for filtering losses.
The floor mounted mitsubishi electric units installed by the diamond contractors at carefree air conditioning heating feature quiet operation and air filtration systems to improve indoor air quality.

A purifier with a hepa high efficiency particulate air filter is designed to remove at least 99 97 percent of dust pollen mold and bacteria plus all airborne particles 0 3 microns or larger.
Air barriers are intended to resist the air pressure differences that act on them.
In order for a ceiling mount filter no matter the size to filter 99 9 of the dust it would have to be discriminate meaning it rejects already filtered air and do it so quickly that no dust had a chance to settle.
In addition i have a ceiling mounted shop dust filtration system moving air at over 900 cfm and capturing a claimed 99 of particles down to 5 microns in size.
Professionals tend to recommend a return duct filter more often than a supply duct filter but some believe no vent filter is the best scenario for any hvac system because of increased air resistance.
Measuring up at just 14 x 32 x 26 inches it s roughly the same size as its competitors but packs a little more weight at 57 pounds.
Air filters do some good right over a source like a lathe or sander.
I routinely measure 400 to 600 cfm at the machine dust collector pipe interfaces even the ones furthest from the cyclone.
Rigid materials such as gypsum board exterior sheathing materials like plywood or osb and supported flexible barriers are typically effective air barrier systems if joints and seams are sealed.
As important as the air cleaner size is how and where you mount it.
