The Hifine KQ-31 air purifier filter is engineered as a direct replacement for Xiaomi Mi Mijia air purifier parts, specifically compatible with the 2S and 2 Pro cartridge filters. Constructed from a durable multi-layer material that includes a primary filter net, melt-blown layer, and activated carbon, this filter is designed to capture airborne particles and odors efficiently. Its precise dimensions—200mm outer diameter, 145mm inner diameter, and 290mm height—ensure a seamless fit and optimal airflow within the purifier unit. The product is manufactured in Jiangsu, China, with high-quality standards and supports customization in color and branding through various printing methods such as silk screen, laser, hot stamping, and UV printing, making it suitable for bulk orders and private labeling.
In real-world applications, this filter enhances air quality in diverse environments including cars, hotels, and households by removing contaminants through its advanced filtration layers. The melt-blown material provides fine particle filtration, while the activated carbon layer effectively absorbs odors and volatile organic compounds, ensuring cleaner and fresher air. Its reliability is backed by a 1-year warranty, though no after-sales service is provided, emphasizing its durable build and low-maintenance design. With a package size of 25x25x35 cm per batch and a gross weight of 3.000 kg, it is easy to handle and ship, supporting power sources such as USB, battery, and electric for versatile use. This filter is ideal for businesses seeking OEM/ODM solutions with a minimum order quantity of 100 units, offering a cost-effective and high-performance alternative to original parts.
