What makes AllergenBlock different
- AllergenBlock defense layer neutralizes over 90% of allergen properties such as pollen, dust, and pet dander on the filter surface, helping reduce common irritants in the room.
- Four layers of filtration work together with a carbon layer to reduce light odors and keep air feeling fresh between cleanings.
- Designed for optimal performance with Blue Pure 411i Max and Blue Pure 411a Max purifiers, offering a seamless upgrade path.
The combination of multi layer filtration means the purifier can handle a broad range of common airborne irritants. When used around the clock, you may notice a more consistent sense of air clarity in spaces like bedrooms, living rooms, and home offices.
Two practical benefits you can expect
- Cleaner air contact: AllergenBlock targets pollen, dust, and pet dander on contact, contributing to a calmer indoor environment.
- Odor management: The carbon layer helps reduce light household odors for a more neutral room aroma.
Convenience and replacement are built in
- Compatible with Blue Pure 411i Max and 411a Max purifiers for a straightforward upgrade without extra equipment.
