The answer to 'air filter vs' is that air filters and air purifiers serve different purposes in your home's HVAC system. Air filters are designed to trap dust, dirt, and other large particles to keep your system running efficiently, while air purifiers use advanced technology to remove smaller airborne contaminants like allergens, germs, and odors. The choice between the two depends on your specific needs and indoor air quality goals.
Air filters are a necessary component of any HVAC system, as they protect the equipment from damage and maintain airflow. They come in a variety of sizes, materials, and efficiency ratings to match your system. In general, higher MERV-rated filters capture more particles but may restrict airflow more, so it's important to choose the right balance for your home. Air purifiers, on the other hand, use technologies like HEPA filtration, activated carbon, or UV light to actively clean the air, making them a good option for those with allergies, asthma, or other indoor air quality concerns.
