Floor Vs Ceiling Air Filtration

Air filters do some good right over a source like a lathe or sander.

Floor vs ceiling air filtration.

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. As important as the air cleaner size is how and where you mount it. Unlike the two blueair models above the honeywell hpa300 is designed to sit on either a tabletop or the floor and has a convenient carrying handle. 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.

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 fully furnished room however may be a difficult space to install a floor mounted unit since it may be obstructed. I routinely measure 400 to 600 cfm at the machine dust collector pipe interfaces even the ones furthest from the cyclone. 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.

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. Air barriers are intended to resist the air pressure differences that act on them. The filter efficiency is high the airflow outstanding. 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.

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. 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.
