What Is A Furnace Filter For Dust Control?
A furnace filter for dust control is a filter with a higher MERV rating that can control, capture, and hold a maximum amount of dust.
Pretty much any AC filter will capture some dust, that is basically their main purpose. However, if you are tired of cleaning dust from around your home, then a higher MERV filter is the way to go.
In my opinion as a home inspector, I recommend buying a furnace filter with at least a MERV 11 filter rating for dust control.
What Are A/C Filter MERV Ratings?
MERV stands for Minimum Efficiency Reporting Value and it is a filtration rating created by ASHRAE (American Society of Heating, Refrigeration, And Air Conditioning Engineers).
Basically, the MERV rating specifies how the filter captures particles at its worst. It doesn't take the average of how well the filter performs or picks the highest amount --- MERV measures the lowest performance of the filter.
MERV ratings range all the way from MERV 1 up to as high as MERV 16. Anything above MERV 16 is in the HEPA filter range and isn't used in residential houses.

What Size Are Dust Particles?
Dust is actually a catch-all term for hundreds of different microscopic particles.
Dust particles can have a large size range from 0.5 microns and all the way up to 100 microns. In comparison, a human hair is in the 50-100 micron size range.
Most dust in a typical household is 5 microns or less however.
Sources of Dust
There are many different sources to household dust, and most dust actually comes from the outdoors through open windows, cracks, and human traffic.
One of the biggest sources of exterior dust is on the bottom of our shoes. In addition, there are interior sources of dust like human skin cells, pet dander, and dust mites.
Household dust can also be a repository for heavy metals.
What Are The Hazardous PM2.5 Dust Particles?
PM2.5 stands for particulate matter that is 2.5 microns in size or smaller.
These dangerous particles are small enough to be breathed into the deeper part of our lungs and can even enter our bloodstream. Even though many of these tiny particles dissolve in our bodies, some of them do not, and can cause serious diseases.
An A/C filter with a MERV 11 rating will capture 90 to 98% of the particles in the 1 to 3 micron range.

Why Not A Higher MERV Rating For Dust Control?
A higher MERV rating for your HVAC system is definitely a possibility, but it isn't advisable for most homeowners.
A higher MERV rating will restrict air flow even more and may damage your system.
If you want a higher MERV filter, I would recommend checking with your HVAC manufacturer to see if your system is compatible.
