Indoor Air Quality in Belleville, NJ

Indoor Air Quality in Belleville

Much of Belleville's housing was built before central cooling was normal and often before ductwork was, so heating and cooling arrived separately and at different times. That is why so many houses here run a boiler for heat and something entirely different for cooling.

About 34% of homes in Belleville were built before 1940 — old enough to have been built with radiators and no ductwork at all; 78% of them heat with natural gas, so furnace and boiler work is the bulk of what comes up here. (US Census ACS 2022)

Ventilation, and the tighter houses that need it

Older leaky houses ventilate themselves, badly and expensively. Newer tight ones do not ventilate at all unless something makes them.

When it matters

A well-sealed newer house, or an older one after serious air-sealing work, can hold onto cooking moisture, VOCs and CO2 to the point where the air feels stale. That is a ventilation problem and no filter solves it.

ERV and HRV

Energy and heat recovery ventilators bring fresh air in and stale air out while transferring most of the heat — and in an ERV, some of the moisture — between the two streams. You get the air change without throwing away what you paid to condition.

Radon is a separate matter

Worth knowing in this state: parts of northern and western New Jersey sit on geology with elevated radon potential, and radon mitigation is its own trade rather than an HVAC add-on. Testing is inexpensive. If you are already thinking about indoor air, test for it.

Filtration: grade and fit, not brand

Filters are rated by MERV, which measures what proportion of particles of a given size they capture. Higher captures more — and higher also resists airflow more, which is where people get into trouble.

The trap with high-MERV filters

Fitting a dense MERV 13 filter to a system designed for a cheap MERV 8 restricts airflow. The furnace overheats and trips its limit switch; the AC coil freezes. People then conclude the system is failing when they have simply choked it. If you want higher filtration, the answer is more filter area — a four- or five-inch media cabinet — not a denser one-inch panel.

Fit matters as much as grade

Air takes the easy path. A high-grade filter with a half-inch gap around the frame filters very little, because the air goes round it. A properly sealed MERV 8 outperforms a loose MERV 13.

Wildfire smoke

Smoke is fine particulate, which is exactly what filtration is good at — and after June 2023 this stopped being theoretical in New Jersey. MERV 13 captures a meaningful share of that size range. Where the system cannot take it, a well-sized portable air cleaner in the room you actually occupy does more than an underperforming central filter.
