The steep hills and historic neighborhoods of Dobbs Ferry create a unique environment for household dust. Many homes located near the Old Croton Aqueduct or along the Hudson River are exposed to high levels of seasonal pollen and riverfront sediment.
Due to the age of the housing in the village, original window casings and door frames often have small gaps that let fine outdoor particulates enter the home. If you find yourself cleaning surfaces more often than your neighbors, the combination of our local geography and older home construction is likely the main reason. In that case, we recommend calling your local Dobbs Ferry HVAC team at A. Borrelli Mechanical to help improve your indoor air quality.
1. Your HVAC Filter is Cheap
Standard fiberglass filters often let the fine dust common in Westchester slip right through. For 2026, we recommend upgrading to a MERV 13-rated filter. While a UV light system is excellent for killing bacteria and viruses, it should be paired with a high-quality pleated filter to physically capture the dust particles before they settle on your furniture.
2. Your HVAC Filter is Old
Your HVAC filter should be changed every 90 days, especially after a long summer of use. If you start to see dust collecting more than usual, think about when the last time you replaced your filter was.
3. Your Carpet Needs to be Cleaned
Dust settles also settles into places you don’t see, like your carpet. Try to vacuum one or twice a week in order to avoid kicking dust back into the air to settle elsewhere.
4. Your Windows and Doors are Open
It’s finally cool enough to keep the windows open and let the fall breeze come in. But keep in mind that with the air also comes outdoor allergens. Pollen and dust can get blown into your home, causing dust to accumulate more quickly.
5. You Have Leaky Air ducts
If you start to see dust piling up after you run your HVAC system, it could be a sign you have leaky air ducts. If your HVAC pipes and ducts aren’t properly sealed, particles can reverse back into the air and leave excess dust in your home.
6. Your Humidity Level is Off
Just like humid air can create a home for mold, dry air is the perfect breeding ground for dust. Finding an equilibrium in your home’s humidity level is essential to not only your health, but your HVAC system’s as well.
In Dobbs Ferry, managing humidity is a year-round battle. During the winter, the air in our older homes becomes extremely dry, allowing dust to remain airborne longer. In the summer, the humidity from the river can cause dust to stick to surfaces and ductwork, leading to mold concerns. Maintaining a consistent 40-50 percent humidity level is the most effective way to keep dust from becoming a constant nuisance.
7. You Need an Air Purifier
An air purifier’s job is to remove dust and particles from the air that eventually settle into layers on your surfaces. This is particularly useful for people with allergies and asthma.
As of 2026, many Dobbs Ferry homeowners are installing smart indoor air quality (IAQ) monitors. These devices provide real-time data on particulate matter levels. This is particularly helpful in the Rivertowns, where humidity fluctuates wildly. When these sensors detect a spike in dust or pollen, they can signal your HVAC system to automatically increase filtration cycles. This proactive approach keeps your air clean without you having to manually adjust settings every time the wind picks up off the Hudson.
