Are you trying to decide between an ionizer and an air purifier? Both are great options for improving the air quality in your home, but they have different strengths and weaknesses. Ionizers are a great alternative to air purifiers for those who don't suffer from allergies or asthma, as they are better at removing smaller molecules such as bacteria and viruses. Unlike air purifiers, ionizers don't require you to change the filter, making them easier to maintain. Ionizers can purify a larger area than HEPA air purifiers and can remove smaller particles from the air. However, they don't remove particles from circulation, instead charging them to attach to something else.
This means that you need to regularly dust or vacuum your home in order to remove particles that have fallen to the floor. On the other hand, air purifiers use filters to capture particles from the air, which need to be changed regularly. If the presence of ozone is a problem for you, then an air purifier may be a better option. Ultimately, it depends on your individual needs and preferences. If you're looking for a device that is easy to maintain and can remove smaller particles from the air, then an ionizer may be the right choice for you.
However, if you're looking for something that can capture larger particles and reduce ozone levels, then an air purifier may be a better option.
