Keep your Blueair Blue Pure 411 air purifier performing at its best with this Finest-Filters compatible 2-pack replacement filter set. Designed for reliable filtration and a snug fit, these filters help maintain clean, fresh air in your home, bedroom or office.

Dual-Layer HEPA + Activated Carbon

Each replacement filter features a multi-layer design combining high-efficiency HEPA-style media to trap fine particles, and an activated carbon layer to help reduce common airborne odours from pets, cooking, smoke and volatile organic compounds.
