Constant dust usually means duct leaks pulling from attics and wall cavities, a filter bypassing air, or returns drawing from dirty spaces. The HVAC system moves the home's entire air volume many times daily, so small leaks become big dust. Testing traces the source instead of blaming housekeeping.
MERV 8 through 11 fits most residential systems, filtering meaningfully without choking airflow. MERV 13 captures finer particles and needs a system designed for the pressure it adds. Filter thickness matters as much as the rating, and the one inch question has its own article.
Portable HEPA units genuinely clean the room they sit in, and marketing oversells everything past that. Whole home filtration at the air handler treats every room through the ductwork instead. Match the tool to the problem: one bedroom, portable wins. The whole house, the system wins.
Winter condensation means indoor moisture meeting cold glass, and the fix runs two directions. Excess humidity from cooking, showers, and crowded living wants ventilation. Single pane glass wants storm windows or upgrades. Persistent dripping breeds mold on sills, which moves this from cosmetic to worth solving.
Stale air on arrival means the house is not exchanging air while closed up, and tight Boston renovations make it common. Ventilation is the cure: bath fans that vent outdoors, kitchen exhaust used, and mechanical fresh air where the house needs it. The ERV question has a full article.
