Indoor Air Quality in Newark, NJ

Indoor Air Quality in Newark

Equipment in Newark has to cover a wider range than most of the country asks for — hard winter cold at one end and humid stretches in the eighties and nineties at the other. A system sized for the middle of that range disappoints at both ends of it.

About 23% of homes in Newark were built before 1940 — old enough to have been built with radiators and no ductwork at all; 72% of them heat with natural gas, so furnace and boiler work is the bulk of what comes up here. (US Census ACS 2022)

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.

Humidity: two opposite problems

New Jersey manages to have both, six months apart, and they need different equipment.

Dry winter air

Heated air holds humidity poorly, and the result is static, cracked woodwork, dry sinuses and a house that feels colder than the thermostat says. A whole-home humidifier plumbed into the ductwork addresses it. Aim for 30 to 40% in winter — higher and you get condensation on windows and eventually mold.

Clammy summer air

This is the one people misdiagnose. Air conditioning removes moisture only while it runs, and an oversized system reaches temperature and shuts off before it has dehumidified. The house is cold and damp, and turning the thermostat down makes it worse. A whole-home dehumidifier fixes what a bigger air conditioner would not.

The target range

45 to 55% relative humidity, and never above 60% for long — that is where dust mites and mold become comfortable. A $15 hygrometer settles arguments about this far more cheaply than equipment does.
