Is your air purifier not feeling as "fresh" as it used to? In the heart of Dhaka, your air purifier works overtime to battle heavy dust and smog, which means a clogged filter is more than just a nuisance—it’s a health risk. The Xiaomi Smart Air Purifier 4 Lite Filter is your defense system’s core, specifically designed to restore your machine’s factory-fresh performance and keep your indoor air truly "Fortress-Level" clean.

• H13 High-Efficiency HEPA Material: Captures 99.97% of ultra-fine particles, including PM2.5, pollen, and bacteria, which is essential for surviving Dhaka’s peak pollution months.

• 3-Layer Integrated Protection: Combines a primary filter, a high-efficiency filter, and high-quality activated carbon to eliminate both physical particles and unpleasant household odors or VOCs.

• Powerful Odor Absorption: The activated carbon layer works 2x harder to neutralize smells from cooking, pets, or outdoor smog, ensuring your home always smells crisp and clean.

• Smart RFID Tracking: Features a built-in RFID chip that communicates with your Purifier 4 Lite, providing 100% accurate filter life tracking so you never waste money changing it too early or risk health by changing it too late.

• One-Piece Integrated Design: Forget messy replacements; the cylindrical design allows for a 360-degree intake and can be swapped out in seconds, getting your air back to pure status instantly.
