## Features

- Designed for Xiaomi 4 Pro – Not for 4, 4 Lite, or 4 Compact: This replacement filter is made for Xiaomi Smart Air Purifier 4 Pro only. The built-in RFID chip detects the new filter and updates the lifespan counter automatically – manual reset is rarely needed. Double-check your model number on the bottom of your purifier before ordering. This is a compatible replacement, not an original Xiaomi part – brand names shown for compatibility reference only.
- Air Purification in 3 Steps – Traps 99.97% of Dust, Smoke, and Bakhour: (1) Nylon pre-filter – catches sand, hair, and large dust before they reach the main filter. (2) H13 True HEPA – removes PM2.5, pollen, and mould spores from the air. (3) Activated carbon – absorbs Bakhour/incense smoke, cooking fumes, shisha odor, and pet smells. Available in Purple (antibacterial coating) and Grey (standard). For homes with babies, elderly, pets, or smokers.
- Built for Dusty Days – Strong Frame, Sealed Fit: 360° cylindrical design pulls air from all directions. Pleated surface increases filter area – steady airflow and extended service life. EVA sealing ring helps prevent unfiltered air from getting through. Flame-retardant ABS frame stands up to sandstorm conditions. Important: Do not wash this filter – vacuum the pre-filter monthly instead.
- Install in Seconds – No Tools, No Complicated Steps: Swap the old filter in under 2 minutes. Unplug, flip the unit, open the bottom cover, rotate the old filter out, and slide the new one in. RFID chip enables automatic recognition – the purifier detects the new filter automatically. If the indicator stays on, reset manually: with the unit plugged in and on standby, press and hold the fan speed button for 8 seconds until you hear two beeps and see "FILTER RESET" on the display. Replace every 6-12 months – sooner during sandstorm season.
- 90-Day Warranty + 24-Hour Support: Every PINREK filter comes with a 90-day warranty against manufacturing defects. Questions about fit or compatibility? Go to Your Orders → select the order → click "Problem with order" → "Contact seller". Our team responds within 24 hours via desertcart's Buyer-Seller Messaging.
