Common Air Purifier Service Questions

While a whole-house air purification system is more expensive than a portable or room-sized air purifier, they have very different expectations to live up to. Room-level purifiers are available for well under $100, while whole-house units can cost up to several thousand. For individuals in the home with conditions that warrant the use of an air purifier, balancing needs against budget is necessary to determine if the extra cost of a whole-home system is worth it.

If you have a lot of dust in your home, an air purifier can help draw dust, pet dander, and pollen out of the air and trap it in a filter. Air purifiers are especially nice if you have allergies or lots of pets as air purifiers that use a HEPA filter can reduce allergens by up to 99.7%.

Yes, professionals use specialized treatments to remove smoke odors and improve indoor air quality.

While an air purifier can trap mold spores and stop them from spreading around your home, it’s not the most effective solution for tackling the problem. Mold is caused by excess moisture and humidity, so there’s a good chance you have an issue somewhere else in your HVAC system that needs to be addressed.

Air purifiers are meant to kill airborne mold, along with pollen and dirt. Air purifiers are a good option if you have allergies and need a whole-home solution, whereas dehumidifiers are best for naturally damp areas (like a bathroom). Consider getting an indoor air quality test to determine if an air purifier is right for you.
