The Most Common Air Purifier Filters
The most standard air purifier filters are particle sheet units, which are made of millions of very small shards and particles of fiberglass. These shards and particles are randomly shot into the wide frame of the filter, and then in turn when sold, the filter is placed in an air purifier. The question is: how are millions of tiny pieces of fiberglass supposed to stop harmful allergens or airborne particles? It is sort of a coincidence, but not quite.
