You may find that your home is heated and cooled perfectly, but still, something doesn’t feel quite right. You might experience a faint, lingering odor no matter how well you clean; you can never dust quite enough, and your allergies seem to never quit even when you retreat indoors.
Even if your home’s HVAC system is in tip-top shape, there could be another reason why you notice less-than-stellar indoor air quality. Despite having a built-in filter, your heating and cooling system cannot completely remove all contaminants from the air it distributes throughout your home. In some climates, this can result in a variety of signs that you need an air purifier.
