Overview

Refresh the air in living spaces with the Pulluty 2 Pack 45i replacement filters, designed for the Alen Breathesmart Flex Bh400 45i purifiers. This kit brings a complete, ready-to-install filtration system that aligns with the B4-Fresh line, helping maintain a clean-feeling environment without complicated upkeep. Expect crisper air, more comfortable breaths, and fewer distractions from common indoor scents as you go about daily routines.

Each package delivers two full filter units plus six extra pre-filters, providing a practical supply for ongoing use. The filtration stack combines a Pre-Filter, an H13 True HEPA filter, and an Activated Carbon filter to address a broad range of air particulates and odors that can accumulate in homes, offices, and shared spaces.

What’s inside

• Two 3-stage filtration units (Pre-Filter + H13 True HEPA + Activated Carbon) for sustained air purification.
• Six extra replaceable Pre-Filters to extend replacement intervals between full filter changes.
• Compatibility with Alen BreatheSmart Flex Bh400 45i models (Part # B4-Fresh / FL40-Silver-Carbon).

How it works

The combination of stages targets a broad spectrum of air contaminants. The H13 True HEPA layer captures particles as small as 0.3 microns, while the activated carbon layer helps reduce odors and some aromatic compounds. This triad works together to support a sense of freshness in spaces like living rooms, bedrooms, or home offices—especially in homes with pets, cooking activities, or everyday dust.

• Pre-Filter traps larger dust, hair, and fibers to keep the main filter performing at its best.
• H13 True HEPA filter delivers high-efficiency particle capture for cleaner air.
• Activated Carbon reduces odors and improves overall room fragrance without masking them.

Use cases and practicality

Ideal for pet owners, apartment dwellers, and busy households where air quality matters. Whether you’re unwinding after a long day or creating a comfortable workspace, this filtration setup supports a lighter, more breathable atmosphere without making promises about outcomes.

Regular replacement helps maintain consistent performance. The packaging notes a straightforward, tool-free installation so you can swap components quickly during a break in your routine, without specialized equipment.

Maintenance and service

For best results, replace the True HEPA filter every 9–12 months and the Pre-filter every 3 months, depending on usage and air quality. The kit’s design emphasizes ease, with a simple, tool-free replacement process and clear guidance for timing replacements.

• Change the True HEPA filter on a 9–12 month cycle for sustained performance.
• Swap pre-filters every 3 months to keep the main filter effective.
• Contact Support if you encounter any installation questions or concerns about fitment.
