Indoor Air Quality — Albany & the Mid-Willamette Valley
Measure the air, then match the equipment.
A whole-home dehumidifier doesn't fix a particulate problem. An air purifier doesn't fix a humidity problem. The right answer depends on what your home actually has going on, so a technician walks the house, takes readings room by room, and matches equipment to data instead of to a generic "allergy package" or a wildfire-season upsell.

Three problems that look the same.
"My allergies are bad" can mean any of them. The data tells you which one you have.
Particulate-driven
Pet dander, dust mite waste, pollen, wildfire smoke, road dust. Measured by PM2.5 and PM10 counts. The answer is higher-MERV whole-home filtration sized to your blower, plus envelope sealing if outdoor air is leaking in.
Humidity-driven
Mold spores from a damp basement, dust mites thriving above 55% relative humidity, condensation. The answer is whole-home dehumidification, basement and crawl-space sealing, vapor management. A filter alone won't move the needle.
Stagnation-driven
Tight modern homes accumulate CO2 and VOCs because they don't breathe. Measured by CO2 readings above 1,000 ppm. The answer is controlled fresh-air ventilation that brings filtered outside air in without losing heating efficiency.
Tell us what you're noticing.
Each of these points at a different reading.
Allergies are worse indoors than out.
Points at particulates: dander, dust mite waste, pollen leaking in around the envelope.
The basement smells musty.
Points at humidity. Mold and dust mites thrive once relative humidity sits above 55%.
The house feels muggy even when it's cool.
PNW summers and shoulder seasons hold indoor humidity in the 55 to 65% range.
Smoke season means closing up the house.
Outdoor AQI goes hazardous and a home without proper filtration ends up nearly as bad inside.
Winter brings static shocks and cracked floors.
Points the other way: winter humidity below 30% in a tightly sealed newer home.
The air feels stale by evening.
Points at ventilation. CO2, cooking VOCs and moisture accumulate in a house that doesn't breathe.
Equipment chosen by your data, not by a bundle.
A technician takes readings room by room — humidity, particulates, VOCs, CO2 — and if the measurements don't justify a piece of equipment, the recommendation doesn't include it.
Six categories. Matched to the measurement.
Each one solves a specific problem the assessment surfaces. Nothing here goes in on a hunch.
Whole-home media air cleaners.
A 4 to 6-inch media cabinet in the return plenum, MERV-13 to MERV-16, sized to your blower's static pressure capacity. It outperforms a 1-inch filter slot by a wide margin and runs 6 to 12 months between changes. We measure static pressure first to confirm the blower can support the rating.
What it means: Right when the PM2.5 baseline is elevated, when allergies track dust, dander or pollen, or when you want wildfire smoke covered.
HEPA-grade smoke filtration.
High-MERV or HEPA-grade media with activated-carbon stages for smoke-specific VOCs and gas-phase contaminants, for homes that lived through the 2020 and 2023 smoke events and want a permanent answer. It ties into the envelope and ventilation strategy rather than standing alone.
What it means: Right for any Albany-area home that wants smoke season covered before it arrives.
Whole-home dehumidifiers.
Integrated with the HVAC return, pulling excess moisture out of the whole house. Pacific Northwest summers and shoulder seasons hold indoor humidity in the 55 to 65% range, which promotes mold and dust mites and makes a house feel muggy at a perfectly reasonable temperature. Drier air lets you hold the thermostat higher and still feel cooler.
What it means: Right when indoor humidity runs consistently over 55%, when the basement smells musty, or where there's mold history.
Whole-home humidifiers.
Bypass or steam style, integrated with the HVAC supply. Less common here than in colder, drier climates, but useful in tightly sealed newer homes where winter humidity drops below 30%. Bypass units are simpler and cheaper; steam gives precise control.
What it means: Right when winter humidity reads under 30%, with static electricity, dry sinuses or cracked wood floors.
UV-C light systems.
Coil-mounted UV sterilizes biological contamination on the evaporator coil, which keeps the coil clean and protects long-term efficiency — strong value during a system replacement. In-stream UV, meant to disinfect air as it passes, has more variable real-world effectiveness, and we'll say so.
What it means: Right during a system replacement, with recurring coil contamination, or in a high-humidity environment.
Fresh-air ventilation (ERV/HRV).
Energy-recovery or heat-recovery ventilators tied into the HVAC return. They bring filtered outside air in while recovering heat (HRV) or heat and moisture (ERV) from the exhaust air, so you ventilate without paying the energy penalty.
What it means: Right when indoor CO2 runs above 1,000 ppm, in newer construction, with cooking VOC concerns, or at high occupancy.
Two ways to recommend air quality equipment. One reads the data.
The other reads your symptom.
| What is being compared | Typical recommendation | Tru72 recommendation |
|---|---|---|
| The diagnosis | "You said allergies, so here's a purifier." The verbal complaint drives the recommendation whether the real problem is humidity or ventilation. | Symptoms verified by measurement. Humidity, particulate counts, VOC and CO2 readings taken in your home, and the actual driver surfaces in the data. |
| Filter selection | A high-MERV filter installed with no static-pressure check. It starves the blower, airflow drops, the system runs hot and the equipment pays for it. | MERV matched to blower capacity. If the blower can't support the rating you want, we discuss a blower upgrade or a larger filter cabinet before the filter goes in. |
| The package | A bundle sold to every customer: UV light plus purifier plus humidifier on every install, needed or not. | Each piece justified by its measurement. If humidity is fine you don't get sold a dehumidifier; if CO2 is normal you don't get sold an ERV. |
| Wildfire smoke | Treated as a one-time crisis. You call during a smoke event, get a temporary fix, and the problem returns next year. | Treated as a recurring PNW condition. Permanent filtration sized for smoke events, with envelope and ventilation strategy included, so smoke season becomes just a season. |
| Who picks | The rep. The recommendation skews toward whatever carries margin this month. | The data. No quota, no commission target, and the quote is itemized so you see what each piece costs. |
The wildfire smoke stack, in order.
2020 and 2023 made smoke a permanent Albany-area condition rather than a once-a-decade emergency. Tru72 installs the filtration and the ventilation directly and coordinates with envelope specialists when sealing is part of the recommendation.
Filtration
High-MERV or HEPA-grade media with carbon stages for smoke VOCs, sized to your blower.
Envelope
Find and seal the leaks that let outside air in: door sweeps, window weatherstripping, attic and crawl-space penetrations.
Fresh-air ventilation
An ERV or HRV with a smart controller that closes the intake when outdoor AQI passes your threshold.

Common questions about indoor air quality.
Plain answers from a diagnostic-first crew.
What is indoor air quality, and why does it matter in Albany?
Indoor air quality refers to the air your HVAC system circulates through your home: temperature, humidity, particulate level, allergens, VOCs, and outside contaminants that make their way in. It matters in Albany for three specific reasons. First, wildfire smoke events in summer regularly push outdoor air-quality index into hazardous range, and homes without proper filtration end up nearly as bad inside. Second, Pacific Northwest winters are humid; many homes have moisture issues that promote mold and mildew. Third, allergens (pollen, pet dander, dust) accumulate in ductwork and on coils over time. The right IAQ equipment depends on which of these you actually have.
How does Tru72 figure out what my home actually needs?
Measurement first. A Tru72 technician measures humidity room by room, baseline particulate counts (PM2.5, PM10), VOC and CO2 readings where indicated, and inspects the existing ductwork and equipment for contamination sources. The diagnostic surfaces which problem you actually have. A whole-home dehumidifier does not fix a particulate problem. A purifier does not fix a humidity problem. We match the recommendation to the measurement, not to a generic "allergy package."
What can I do about wildfire smoke?
A permanent solution combines three things: a high-MERV or HEPA-grade whole-home media filter sized to your blower, a sealed building envelope (no smoke leaking around windows and doors), and a controlled fresh-air ventilation system that lets you pull air in through filtered intake only when outdoor AQI is acceptable. Tru72 installs the filtration and ventilation; tightening the envelope is sometimes part of the recommendation depending on your home.
Do I need a whole-home dehumidifier?
Maybe. Pacific Northwest homes vary widely on indoor humidity, and the answer depends on the actual readings. Homes with humidity consistently above 55 to 60% (especially basements, crawl spaces, and shoulder-season conditions) benefit meaningfully from dehumidification: better comfort at lower thermostat settings, less mold risk, and reduced dust mite activity. We measure before we recommend.
Are UV-C lights worth it?
For most Albany-area homes, a coil-mounted UV-C system is a worthwhile addition during a system replacement. It keeps the evaporator coil sanitized, which protects long-term efficiency and reduces biological contamination in the air stream. Air-stream UV (designed to sanitize air as it passes through the system) has more variable effectiveness; we'll discuss when it makes sense and when it doesn't.
What about fresh-air ventilation (ERV/HRV)?
Modern, well-sealed homes can have CO2 buildup, VOC accumulation, and stale air without active ventilation. ERVs (Energy Recovery Ventilators) and HRVs (Heat Recovery Ventilators) bring in filtered outside air while recovering heat or moisture from the exhaust air, so you ventilate without losing your heating or cooling efficiency. For newer Albany homes and any home where indoor CO2 measures consistently above 1000 ppm, ERV/HRV is a strong recommendation.
Will an air purifier really help my allergies?
If your allergies are particulate-driven (pet dander, dust mite waste, pollen leaks), a properly sized whole-home media filter in the MERV-13 range or higher will measurably reduce indoor exposure. If your allergies are humidity-driven (mold spores from a damp basement, dust mites thriving in high humidity), a dehumidifier and air sealing are the real answers and a purifier alone won't move the needle. The measurement tells you which one you have.
Can I add IAQ equipment to my existing HVAC system?
Almost always, yes. Whole-home media filters, UV-C systems, fresh-air intakes, and dehumidifiers integrate into existing ductwork. The exception is when the blower in the existing system can't handle the additional static pressure of higher-MERV filtration; we measure static pressure before recommending a high-restriction filter to avoid starving the system.
Measure the air before you spend on the equipment.
A 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.
