An ion purifier is a good low-cost solution for general air cleaning, especially if viruses and VOCs are a problem. However, for those with respiratory problems or conditions, a HEPA purifier will provide maximum effectiveness. The first and main difference between ionic air purifiers and HEPA air purifiers is the technology used to clean indoor air. Any filter that seeks to comply with the HEPA standard must remove at least 99.97% of particles with a diameter of 0.3 micrometers.
Although ionic air purifiers are usually standalone units, some manufacturers have also started to include air ionizers as part of standard air purifiers with a HEPA filter. So, if you're still leaning toward an ionic air purifier, it's better to opt for one with a built-in HEPA filter than a standalone unit. While HEPA purifiers trap contaminants in their filters and effectively remove them from the air, ionic air purifiers simply cause them to adhere to various surfaces in the room, such as walls, floors, curtains, tables, and even people. If you're wondering if HEPA filters will let more particles through as they get dirty, don't worry. The main filter used is the High Efficiency Particulate Protection (HEPA) filter, from which the air purifier derives its name.
Common standards require a HEPA air filter to remove at least 99.97% of particles whose diameter is greater than or equal to 0.3 μm from the air that passes through it. They also do not allow particles to pass through them: HEPA filters are capable of capturing 99.97% of particles with a diameter of 0.3 microns. HEPA purifiers do not present these health problems, but they require timely replacement of filters to ensure efficient operation, increasing their overall cost. Both ionic air purifiers and standard air purifiers with HEPA filters have advantages and disadvantages.
In fact, a HEPA filter traps pollutants from the air, but it can lose its effectiveness once it becomes clogged with debris. HEPA air purifiers with carbon help filter out the smallest contaminants, as well as fumes, smoke, and other odors. HEPA filters can be more expensive, although there are benefits to operating them that can offset those costs, depending on your budget and needs. HEPA filters are particularly effective at eliminating odors, as well as the smallest particles of dust and contaminants.
The maintenance costs of passive air purifiers include the periodic replacement of HEPA and active carbon filters, while active air purifiers usually do not entail any maintenance costs other than regular service. A HEPA air purifier uses a fan to suck in ambient air and pass it through a series of air filters.
