The Association of Home Appliance Manufacturers suggests considering the room size when selecting an air purifier to ensure it effectively circulates air throughout the space.

4. Maintenance and Filter Replacement:
   Maintenance and filter replacement specify the frequency and cost of replacing filters. Budget air purifiers often require filter changes every 3 to 6 months. It’s essential to factor in this cost when considering overall value. Research by the National Institute of Environmental Health Sciences indicates that neglecting filter maintenance can decrease an air purifier’s efficiency dramatically.

5. Additional Features:
   Additional features may include ionizers which charge particles in the air, causing them to stick to surfaces rather than remaining airborne. However, ionizers can produce ozone, which might be harmful in high concentrations. The EPA advises that ionizers should be used cautiously, as ozone can affect respiratory health.

By assessing these attributes, consumers can choose a suitable air purifier that aligns with their specific air quality needs while remaining within a budget.
