Genuine Xiaomi Replacement Filter Pro

Keep your Xiaomi Smart Air Purifier 4 Lite operating efficiently with the Xiaomi Smart Air Purifier 4 Lite Filter Pro. This all-in-one replacement filter is specifically designed for the Xiaomi Smart Air Purifier 4 Lite and combines multiple filtration technologies in a single filter unit.

Multi-Layer Filtration

The Filter Pro combines a primary filter, anti-bacterial coating, Xiaomi High Efficiency Filter and activated carbon filter to provide comprehensive filtration. These layers work together to capture larger particles, fine airborne particles and household odours.

High-Efficiency Particle Filtration

Xiaomi’s High Efficiency Filter uses electrostatic and mechanical filtration technologies. Xiaomi states that the filter media achieves 99.97% filtration efficiency for particles measuring 0.3μm, based on its specified testing conditions.

Helps Capture Dust, PM2.5 & Pollen

The filtration layer is designed to capture common airborne particles including dust, PM2.5, pollen, pet dander and smoke, helping the purifier deliver cleaner air output.

Anti-Bacterial Coating

The Filter Pro features an anti-bacterial coating designed to help inhibit bacteria and mould growth on the filter surface. Xiaomi reports protection rates of 99.98% against E. coli and 99.99% against S. aureus under its specified testing conditions.

Anti-Mould Protection

The anti-bacterial coating also carries a Grade 0 anti-mould rating according to Xiaomi’s cited testing. This helps maintain the filter surface during regular use.

Activated Carbon Odour Filtration

The integrated high-quality activated carbon layer helps adsorb household odours and certain airborne pollutants. It is designed to help reduce common smells such as pet odours, cooking fumes and cigarette smoke.

Long-Lasting Filter

Xiaomi recommends replacing the Filter Pro approximately every 6–12 months, depending on usage and environmental conditions. The Xiaomi Home app can also monitor filter usage and provide replacement reminders.

Easy Filter Replacement

Replacing the filter is designed to be straightforward. Switch off and unplug the purifier, open the upper compartment, remove the old filter and install the new Filter Pro. After installation, the purifier’s filter indicator can be reset according to Xiaomi’s instructions.

Designed Exclusively for the Xiaomi Smart Air Purifier 4 Lite

The Filter Pro is specifically compatible with the Xiaomi Smart Air Purifier 4 Lite. Xiaomi states that the 4 Lite filter is unique and is not interchangeable with older Xiaomi purifier models.

Purple Filter Design

The Filter Pro has a distinctive purple finish and measures approximately 175mm in external diameter and 310mm in height.

Ideal for Regular Air Purifier Maintenance

Replacing an exhausted filter helps maintain the intended filtration performance of your Xiaomi Smart Air Purifier 4 Lite. Keep a replacement available so your purifier can continue providing everyday air purification without unnecessary interruption.
