This replacement filter kit is designed specifically for Shark Performance Lift Away models UV850, UV900, and DuoClean upright vacuums, offering a cost-effective alternative to original components like Part #XHF320 and XFFK602UKT. The set includes two HEPA filters and four foam & felt filters, crafted from high-efficiency materials that capture fine dust, allergens, and pet dander without compromising airflow. Each HEPA layer is constructed with dense microfibers to trap particles as small as 0.3 microns, while the foam and felt layers provide pre-filtration for larger debris, extending the life of the main filter. The materials are bonded with a sturdy frame that resists deformation under repeated use, ensuring a snug fit inside the vacuum housing.

The foam inserts are open-cell polyurethane with moderate compression resistance, and the felt layers use thermally bonded polyester fibers for consistent porosity. This combination balances filtration performance with air permeability, allowing the vacuum to maintain strong suction across carpet and hard floors. The outer casing of the filters uses a rigid plastic rim that aligns with the vacuum’s locking mechanism, preventing air leaks and reducing vibration during operation. The manufacturing process involves automated cutting and ultrasonic sealing to minimize loose fibers or frayed edges.

Quality control checks verify dimensional accuracy and seal integrity before packaging. The kit is suitable for households with pets or allergy concerns, as the HEPA component reduces airborne irritants effectively. The foam and felt layers can be rinsed under running water and reused after drying, while the HEPA filters require replacement every few months depending on usage frequency.

This set offers a practical maintenance solution that helps restore vacuum performance without the expense of brand-name replacements. The materials are selected for durability under moderate to heavy use, with the foam maintaining shape after multiple washes. The filters work with the UV850, UV900, and DuoClean models that share the same filter compartment design.

The overall construction emphasizes reliability and consistent output, making it a practical choice for regular household cleaning. The packaging includes clear instructions for installation, though the process is straightforward with no tools required. This kit provides an affordable way to maintain peak suction and air quality between full vacuum service intervals.
