Ion generators, activated carbon, absorbents, chemicals, catalysts, etc. And clean the air to the designed level before it enters
Other filters for further purification. Air purification equipment with pre-filters is used in buildings, vehicles and public areas
And industry. The technical and user-defined requirements for air pre-filters are diverse, so there are no standardized regulations regarding performance and effectiveness. Many commercial options of air pre-filters are available for air filtration units in homes, workplaces, hospitals, hotels, transportation vehicles, and personal respirators.
The pre-filter is usually a reasonably priced or washable filter, and it is used in some air purifiers to maximize the performance of the main filter
Lifespan. We suggest purchasing an air purifier with a pre-filter, as they can save you money in the long run. They are not essential, but they can extend the lifespan of your main filter, which means your air will be cleaner and last longer.
Pre-filters are usually made of cheap and disposable materials, or (more commonly) they are made of more durable and washable materials. Generally, pre-filters have a long service life because they need to be cleaned rather than discarded. This is different from most air filters on the market, including HEPA filters.
