These are replacement H13 HEPA filters for the Alen BreatheSmart 35i air purifier, sold in a five-pack. H13 is medical-grade filtration, so the media captures fine particles down to 0.3 microns at high efficiency, the same class Alen uses across its purifier line. The five-pack suits owners who run the 35i continuously and want spares on hand instead of buying one filter at a time. Alen offers several filter variants tuned to different environments, so check that the pack matches the variant you want.
