As you learned, a HEPA air purifier can be more efficient at removing pollutants from the air because it actually traps the particles inside a physical filter. An ionizer, on the other hand, doesn’t remove the contaminants but causes them to drop out of the air you breathe.
Is an ionizer better than a HEPA filter?
Conclusion. Ionic air purifiers are quiet, cost-efficient, and filter-free. HEPA filters are particularly effective at removing odors as well as the smallest particles of dust and pollutants. Either way, you will enjoy the benefits of cleaner, fresher air.
Are ionizers better than purifiers?
Should you get an air ionizer or an air purifier? Objectively, HEPA air purifiers do a better job of cleaning the air and trapping pollutant particles than ionic air purifiers, so we’d usually recommend an air purifier over an air ionizer, especially if you have allergies.
Do air ionizers work for Covid?
Portable air cleaners and HVAC filters can reduce indoor air pollutants, including viruses, that are airborne. By themselves, portable air cleaners and HVAC filters are not enough to protect people from the virus that causes COVID-19.
What is better than HEPA filters?
ULPA filters trap more and smaller particulate matter than HEPA filters. ULPA filters are 99.999% effective at removing submicron particulate matter of 0.12-micron diameter or larger, while HEPA filters are 99.97% effective for eliminating particulate matter of 0.3-micron diameter or larger.
Is breathing ionized air safe?
The negatively charged ions produced by air ionizers are not harmful and will attract and trap the charged particles including the potentially harmful particles in the air which if untreated could lead to throat irritation or respiratory infections. This will leave the air safer for a healthy environment.
Why is ionized air bad for you?
The most common air ionizer dangers include throat irritation, coughing, chest pain and shortness of breath, as well as an increased risk of respiratory infections. However, these ionizer air purifier side effects only occur if you inhale ozone. … Only ozone generators are a concern.
What is the difference between HEPA filter and air purifier?
Air cleaners filter the air (HEPA air cleaners for instance) while air purifiers sanitize the air by emitting negative ions, ozone, utilizing heat (Airfree air purifiers) or with UV or UVC lamps. Air cleaner strengths: Filters the air and collects dust, especially the larger dust (mostly dead skin) and pet dander.
Do HEPA filters produce ozone?
If you decide to purchase a portable air cleaner, filtering air cleaners with High Efficiency Particulate Air (HEPA) filters are recommended because these do not emit ozone but do remove particulate matter from the air.
Are all air purifiers HEPA?
Generally we test only purifiers with HEPA certification. In the North American definition, “true HEPA” means that a filter removes at least 99.97% of airborne particles of a 0.3-micron diameter in a single pass.
Does a HEPA filter stop COVID-19?
Oct. 11, 2021 — A combination of HEPA filters and UV light was effective in reducing airborne COVID particles from the air of hospitals in the first test of its kind, researchers reported.

How does a HEPA filter work?
HEPA stands for high-efficiency particulate air. A HEPA filter is a type of mechanical air filter; it works by forcing air through a fine mesh that traps harmful particles such as pollen, pet dander, dust mites, and tobacco smoke. You can find HEPA filters in most air purifiers.
Is HEPA filter the best?
HEPA is good at removing larger particulate matter like pet dander, pollen and dust mites. Unfortunately, mold, VOCs, viruses, bacteria, and small particulates under 0.3 micrometers can not be removed safely from the air with an HEPA-based air purifier.
Can I wash a true HEPA filter?
A washable HEPA filter should be cleaned by rinsing it under cold water. You should be careful not to touch the filter material, only allowing it to come in contact with water. Allow the filter to completely dry before reinstalling it.
How do I choose a HEPA filter?
For HEPA, filtration efficiency must be 99.97% and particles retained must be as small as 0.3 micrometers (formerly microns). The phrase “as small as” is important because it means that if all the particles were 0.3 micrometers in size, the filter would still capture and retain 99.97% of them (“filtration efficiency”).
