    Deep pockets maximize filtering surface area with minimal airflow resistance. These filters catch common allergens such as dander, mold spores, and pollen. High-efficiency filters balance filtration efficiency and airflow, making them more cost-effective than higher-rated filters.

    Purify the air in your most sensitive environments. Since ULPA filters remove 99.999% of particles, they're used in semiconductor, pharmaceutical, and aerospace facilities. Constructed with fibers more densely woven than HEPA filters, they catch 10 times more particles. However, they need to be changed more often because they collect contaminants more quickly.
