This is the replacement HEPA filter for the Alen BreatheSmart 35i air purifier. It is a medical-grade H13 HEPA element rated to capture 99.9% of particles 0.1 micron or larger, and it comes in three versions: Essential (Pure) for dust, viruses and allergens; Advanced (Fresh), which adds a carbon layer for asthma triggers, chemicals, VOCs and smoke; and Ultimate (Odor), which adds carbon plus a catalyst layer for odor, mold and pet-filled homes. It suits 35i owners who want a genuine fit rather than a trimmed generic pad, and the tiered options let you match filtration to your household instead of paying for carbon you do not need. The main trade-off is that you are locked into Alen's own filter line, and the carbon tiers are the ones worth choosing only if smoke, VOCs or pet odor are real problems in your space.
