6 Best air purifiers with pre-filter technology

Categories
Pre-filters capture large particles before air reaches main filter, extending filter life Pre-filter technology in air purifiers serves as the first line of defense against airborne contaminants. This initial filtration stage captures larger particles such as dust, hair, and pet dander before the air reaches the main filter. By trapping these larger pollutants, pre-filters significantly extend the life of the primary filtration system, improving overall efficiency and reducing maintenance costs. Additionally, pre-filters are often washable or easily replaceable, making them a cost-effective component in air purification systems.
