As you learned, a HEPA air purifier can be more efficient at removing air contaminants because it actually traps particles inside a physical filter. An ionizer, on the other hand, doesn't remove contaminants, but instead causes them to come out of the air you breathe. To improve air cleaning performance, HEPA air filters are the best technology. They remove most airborne contaminants, as well as the most dangerous particles.
In addition, HEPA filters become more efficient over time. Which means they eliminate more with use. While it's beneficial from a cost standpoint, it loses a lot in performance compared to a HEPA filter. While ionic air purifiers cost less to operate in the long term, their performance is terrible compared to a HEPA air purifier.
Ionizers don't have filters because they emit electrically charged particles to remove contaminants from the air. The main difference between an ionic air purifier and a HEPA air purifier is that electrostatic collector plates can be washed and reused as they become dirty. A HEPA air purifier works by drawing air into the device through a dense physical filter that traps air contaminants, such as dust, allergens, mold spores, bacteria, and smoke. In the case of air purifiers, HEPA filters trap particles inside a filter, so it needs to be replaced regularly.
Ozone air purification is sold only as a commercial air purifier, as the state of California does not allow them to be sold to consumers. Any filter seeking to comply with the HEPA standard must remove at least 99.97% of particles with a diameter of 0.3 micrometers. If you're wondering if HEPA filters will let more particles through as they get dirty, don't worry. In fact, the larger room size than an air purifier with a HEPA filter can effectively purify that we've seen for sale It is 1560 square meters.
We see this frequently in automotive air purifiers and it's not what you'd expect from an air purification system. Ionizers don't use filters at all, and ionic air purifiers have metal collector rods or plates that can be cleaned with a cloth. As you can see, the main advantage of a HEPA air purifier over an ionizer is that the HEPA unit traps contaminants present in the air and prevents them from re-entering the air you breathe. The main difference between air purifiers and ionizers is the way each device removes contaminants from the air.
If you're looking for an air purifier for your home, you might be confused by the different types: ionic and HEPA air purifiers are the most common.
