Indoor Air Quality Questions, Answered
What is the best way to improve indoor air quality?
Start by reducing pollution sources, addressing moisture, and improving ventilation where appropriate. Filtration can help capture particles. The right combination depends on what is causing the concern.
What is the difference between an air purifier and an air filter?
An HVAC filter captures particles in air passing through it. “Air purifier” is a broader product term that can refer to different treatment technologies. Compare the specific device’s purpose, performance information, and maintenance needs.
Why is my house so dusty even after cleaning?
Dust can come from fabrics, pets, outdoor air, and everyday activity. Filter fit, housekeeping, and duct or building leaks may also be worth reviewing. A home assessment can help narrow down the next steps.
Will an air purifier fix a musty smell?
A musty odor deserves a closer look for moisture and its source. Air treatment alone does not fix leaks or damp materials. Tell our team where you notice the odor and when it returns.
Which MERV filter is right for my HVAC system?
Use an efficient filter that your equipment and filter housing can accommodate. Higher MERV ratings capture smaller particles more effectively, but compatibility and airflow should be checked before upgrading.
Is a home energy audit the same as indoor air quality testing?
No. A home energy audit looks at comfort and building conditions; it is not a substitute for specialized pollutant sampling or laboratory testing. Let us know if you have a specific testing concern so we can discuss the appropriate next step.
How much do indoor air quality improvements cost?
Cost depends on the equipment, installation requirements, and underlying issues. We’ll explain recommended improvements and pricing before you choose the work you want completed.
