Buying advice

When choosing a home air ionizer, consider the room size, filter type (HEPA is best for true particulate removal), and whether you need extra features like UV-C or smart controls. Also factor in ongoing filter replacement costs and noise levels. Ionizers that produce ozone should be used with caution, especially for those with respiratory issues.
