An air purifier removes or neutralizes contaminants in the air, helping you breathe easier and feel better indoors. Depending on the technology, it can trap particles (like pollen and dust), absorb odors, or even neutralize germs with UV light. A whole house air purifier connects to your HVAC system and treats all the air moving through your home, offering protection in every room—not just one area. Radiant installs air purifiers that target the specific needs of your household, from allergies to indoor odors.
