Indoor Air Quality Services in Boulder, CO

Indoor air can be affected by wildfire smoke, pollen, outdoor dust, pet dander, dry winter air, cooking particles, fireplaces, cleaning products, remodeling dust, moisture, limited ventilation, and particles circulating through the HVAC system.

The specific causes vary from home to home, which is why an evaluation should begin with the problem the homeowner is noticing.

An appropriately selected whole-home air cleaner or high-efficiency HVAC filter can help reduce some fine smoke particles circulating indoors. It cannot prevent all smoke from entering or remove every gas associated with wildfire smoke.

During smoke events, homeowners should also keep windows closed, reduce outdoor-air intake when appropriate, use compatible high-efficiency filtration, and replace dirty filters more frequently.

MERV 13 filtration is commonly recommended for capturing smaller airborne particles when the HVAC system can support it. However, not every blower, filter cabinet, or duct system can safely handle the same level of resistance.

A professional should determine the highest-efficiency filter your system can accommodate without reducing airflow or damaging performance.

A whole-home system treats air moving through the HVAC system and can provide broader coverage. A portable purifier treats the room where it is placed and may provide strong localized filtration.

Some households use both: whole-home filtration for general circulation and a portable HEPA purifier in a bedroom or designated clean-air room.

Frequent dust can be related to outdoor air entering the home, an ineffective or poorly fitted HVAC filter, leaky ductwork, pets, carpet and fabrics, renovation activity, open windows, or particles being stirred up faster than they are removed.

Installing a more expensive filter without identifying the source may not solve the problem.

A whole-home humidifier may be helpful when winter air becomes excessively dry and causes discomfort, static electricity, or concerns about wood materials.

The system must be adjusted carefully because too much humidity can create window condensation or moisture problems during cold weather.

A dehumidifier may be worth evaluating if a basement, bathroom, crawlspace, laundry area, or other room consistently feels damp or smells musty.

Before installing equipment, homeowners should rule out plumbing leaks, drainage issues, roof leaks, foundation moisture, and other water sources.

Both systems exchange stale indoor air for outdoor air while recovering energy from the outgoing airstream.

An HRV primarily transfers heat. An ERV transfers heat and also exchanges some moisture. The right choice depends on the home, climate, existing HVAC equipment, occupancy, and humidity needs.

They can be helpful for tighter, remodeled, or energy-efficient homes that need controlled fresh-air ventilation. They may also help homes that feel stale when windows stay closed.

Because they bring outdoor air inside, the installation should include appropriate filtration, controls, maintenance, and an operating plan for poor outdoor air quality.

It depends on the equipment, filtration, outdoor smoke level, and manufacturer controls. Because an HRV or ERV intentionally brings in outdoor air, normal operation may need to be reduced or adjusted during heavy smoke.

A homeowner should understand how to change the operating mode and maintain the intake filter before smoke season.

No. A whole-house fan brings large amounts of outdoor air into the living space through open windows. It should not be used when wildfire smoke, poor air quality, heavy pollen, excessive heat, or outdoor dust would be pulled inside.

Use it only when outdoor temperature and air quality are favorable.

An attic fan exhausts air from the attic and does not directly pull outdoor air through the living space.

A whole-house fan pulls outdoor air through open windows, moves it through occupied rooms, and exhausts it through the attic. The two systems serve different purposes.

An attic fan does not filter or purify the air inside occupied rooms. Its primary purpose is to ventilate the attic and reduce excessive attic heat or moisture under appropriate conditions.

It may indirectly support comfort, but it should not be presented as a substitute for indoor air filtration or whole-home ventilation.

Some air cleaners use activated carbon or similar media to reduce certain odors and gases. Particle filters alone are primarily designed to capture dust, pollen, smoke particles, and other airborne solids.

The effectiveness depends on the source of the odor, the amount of carbon media, airflow, and how frequently the filter is replaced.

No. Standard HVAC filters and whole-home air purifiers are not radon-mitigation systems.

Radon must be measured with an appropriate test. Elevated levels generally require a dedicated radon-mitigation strategy from a qualified provider.

Many residential filters are checked every one to three months, but the actual schedule depends on the filter, HVAC runtime, pets, household dust, construction activity, and outdoor air quality.

Filters may need replacement more frequently during wildfire smoke events or when they become visibly dirty and airflow begins to decline.
