Many people report good results with HEPA air purifiers, which are effective at removing particles like dust and pollen. In terms of eco-friendliness, look for devices with Energy Star ratings to ensure efficiency. Additionally, houseplants can be great for air quality, but they tend to work slower and cover less area than mechanical purifiers. Combining both methods might give you the best of both worlds—clean air and a lovely, natural atmosphere at home. Have you tried any local plant varieties that are particularly effective indoors?
