3-Layer Filter Structure

Xiaomi 4 Pro compatible PURMED filter works with 3-stage structure: pre-filter layer, activated carbon layer and True HEPA layer.

1) Pre-Filter Layer

• It is the first layer to welcome the air.
• Hair, bristles, pet dander, textile fibers, and large dust particles are retained at this stage.
• The goal is to support the filter's lifespan by reducing the unnecessary rapid filling of the HEPA and carbon layers.

2) Activated Carbon Layer

• It helps to reduce odor and some gas molecules.
• Cigarette odor, food/oil odors and various chemical odors are trapped in carbon pores.
• It contributes to refreshing the environment not only in terms of particles but also in terms of odor.

3) True HEPA Layer

• It is a high-efficiency filtration layer that targets fine particles.
• It helps reduce pollen, mold spores, fine dust and similar allergens.
• With its true HEPA structure, it helps to capture micron-level particles.

This triple combination is designed to offer a level of holistic air purification that simple single-layer filters cannot provide.

Lifespan and Replacement Period

As HEPA and carbon filters trap pollutants over time, the pores fill up. From this point on:

• Air passage becomes difficult,
• Even if the device works at the same level, efficiency may decrease,
• The filtration performance and odor reduction effect may be reduced.

As a PURMED technical recommendation, it is recommended to replace the filter, ideally every 8–12 months . This period may be earlier in environments with smoking, heavy dust or pets.

Signs that the time for change is approaching

• Significant weakening of the air outlet,
• A persistent odor in the room,
• Dust/lint accumulation on surfaces faster than normal,
• Visible dirt layer on the filter surface.

It is recommended that you unplug the appliance when making the replacement. Washing the old filter or vacuuming aggressively with a broom not recommended as it may damage the filter structure; The saturated filter should be replaced with a new one.
