What are electronic air filters?
Electronic air filters use electrical charges to attract and deposit allergens and irritants. If the device contains collecting plates, the particles are captured within the system; otherwise, they stick to room surfaces and have to be cleared away. A disadvantage of these units is that almost all of them create small amounts of ozone. Ozone irritates airways, causing temporary bronchospasm in those with asthma, and nasal congestion in those with hay fever or rhinitis.
