A whole-home dehumidifier doesn't fix a particulate problem. An air purifier doesn't fix a humidity problem. The right indoor air quality solution depends on what your home actually has going on, and the only way to know that is to measure. Tru72 walks the home, takes readings room by room, and matches equipment to data, not to a generic "allergy package" or a wildfire-season upsell.
Pet dander, dust mite waste, pollen, wildfire smoke, road dust. Solution: higher-MERV whole-home filtration sized to your blower, plus envelope sealing if outdoor air is leaking in. Measured by PM2.5/PM10 counts.
Mold spores from a damp basement, dust mites thriving above 55% RH, condensation issues. Solution: whole-home dehumidification, basement and crawl-space sealing, vapor management. A filter alone won't move the needle.
Tight modern homes accumulate CO2 and VOCs because they don't breathe. Solution: a controlled fresh-air ventilation system (ERV or HRV) that brings filtered outside air in without losing heating efficiency. Measured by CO2 readings above 1000 ppm.
A Tru72 technician takes readings room by room. Humidity, particulates, VOCs, CO2. The recommendation matches the data, not a generic "allergy package."
A 4 to 6-inch media cabinet installed in the return plenum, much higher-performing than a 1-inch filter slot, and longer-lasting (6 to 12 months between changes). Filtration efficiency increases dramatically once you have the right MERV rating; we measure static pressure first to make sure your blower can support it.
For homes that lived through 2020 and 2023 smoke events and want a permanent solution. Combines high-grade particulate filtration with activated-carbon stages for smoke-specific VOCs and gas-phase contaminants. Integrates with envelope and ventilation strategy.
Pacific Northwest summers and shoulder seasons can keep indoor humidity in the 55 to 65% range, which promotes mold, dust mites, and that "muggy" feel even when the temperature is fine. A whole-home dehumidifier lets you keep the thermostat higher (saving energy) while feeling cooler, and meaningfully reduces biological IAQ issues.
Less common in the PNW than in colder, drier climates, but useful in tightly sealed newer homes where winter humidity drops below 30%. Bypass humidifiers are simpler and cheaper; steam humidifiers give precise control. We measure first.
UV-C light sterilizes biological contamination on the evaporator coil and in the air stream. Coil-mounted UV is a strong value, especially during system replacement: it keeps the coil cleaner, which protects long-term efficiency. In-stream UV (designed to disinfect the air as it passes through) has more variable real-world effectiveness; we'll discuss when it makes sense.
Newer tight homes don't breathe. CO2, VOCs, cooking emissions, and humidity accumulate. ERVs and HRVs bring filtered outside air in while recovering heat (HRV) or heat + moisture (ERV) from the exhaust. You ventilate without paying the energy penalty. Critical for modern construction and any home with consistently high indoor CO2.
If the measurements don't justify a piece of equipment, the recommendation doesn't include it. The honest answer is the one you can trust.
2020 and 2023 made wildfire smoke a permanent Portland-area concern, not a once-a-decade emergency. A real solution combines three things, in this order: filtration that can handle smoke-grade particulates, an envelope that stops smoke from leaking in around windows and doors, and controlled fresh-air ventilation that lets you breathe filtered outside air when AQI allows.
Tru72 handles the filtration and ventilation directly. We coordinate with envelope specialists when sealing work is part of the recommendation. The goal is that by the time the next smoke event arrives, you've already moved on with your day.
A Tru72 technician walks the home, takes readings room by room, and hands you an itemized written recommendation that matches the data. If the data says you don't need a piece of equipment, the recommendation says so. The honest answer is the one you can trust.
Clean. Quality. Comfort.
