Refurbished Set (without box) - A18 nano ions PuriPRO® 24-Months Repla

A4S 24-MONTHS REPLACEMENT FILTER PACK
PuriPRO^®3-in-1 Filter
Cool Catalyst Filter	• Produces reactive oxidants to oxidize and eliminate airborne germs and harmful volatile organic compounds (VOCs). This reaction breaks down the contaminants into carbon dioxide and water molecules under normal room temperature environment.
Granular Activated Carbon Filter	• Removes unpleasant odours and chemicals in the air with its highly adsorbent granules. Each granule contains millions of microscopic pores to provide a large surface area capacity to adsorb volatile organic compounds (VOCs), unpleasant odour and airborne chemicals.
99.97% True HEPA Filter	• It is capable of removing up to 99.97% of airborne allergens and germs with a size of 0.3 micrometer in diameter which includes very fine dusts, haze and smoke particulates, pet dander, mold spores, pollen some bacteria and viruses. • Filter Unit Capacity: Suggested Replacement 24 Months (Approx 9,000 hours) ^Based on average excellent indoor air quality, 12 hours a day, 7 days a week usage under normal domestic indoor environment.
Humidifying Filter
Humidifying Filter	• Adopting an evaporation technology, the humidifying filter fitted inside the water tank, absorbs the moisture and releases it into the surrounding air to help improve the relative humidity level. ^*Filter Unit Capacity: Suggested Replacement 12 Months

Pre-Filter

Pre-filter provides the first layer of air filtering system by capturing larger particles to improve the durability and enhance performance of subsequent filters.

Function
• Oxidize and eliminate airborne germs and harmful volatile organic compounds (VOCs).

Cool Catalyst Filter

Cool catalyst filter produces reactive oxidants to oxidize and eliminate airborne germs and harmful volatile organic compounds (VOCs). This reaction breaks down the contaminants into carbon dioxide and water molecules under normal room temperature environment.

Function
• Oxidize and eliminate airborne germs and harmful volatile organic compounds (VOCs).

Granular Activated Carbon Filter

Granular activated carbon removes unpleasant odours and chemicals in the air with its highly adsorbent granules. Each granule contains millions of microscopic pores to provide a large surface area capacity to adsorb volatile organic compounds (VOCs), unpleasant odour and airborne chemicals.

Function
• Adsorb volatile organic compounds (VOCs), unpleasant odour and airborne chemicals.

H13 HEPA Filter Enhanced with Nano Silver Copper Ions

H13 HEPA filter is equipped with 99.97% filtering efficiency against airborne allergens and germs with a size of 0.3 micrometre in diameter. This includes very fine dusts, haze and smoke particulates, pet dander, mold spores, pollen, bacteria and virus. And through the infusion of a synergistic blend of nano silver (Ag+) and copper (Cu2+) ions into the H13 HEPA filter fibres, these nano ions conduct active elimination of the virus and bacteria trapped in the HEPA filter in 60 minutes, assuring only clean filtered air leaves the air purifier. This serves as an additional protection measure against any potential virus/bacteria transmission or secondary pollution.

Function
• Trap up to 99.97% of airborne allergens and germs such as fine dusts, haze and smoke particulates, pet dander, mold spores, pollen, bacteria and viruses. • The nano silver (Ag+) and copper (Cu²+) ions conduct active elimination of virus and bacteria trapped in the HEPA filter via adhesion, penetration, and oxidative damage.

Built-In Ionizer (Semi-Permanent)

Semi-permanent built-in ionizer produces millions of negative ions to promote air purification through the elimination of airborne allergens and germs. Negative ions also help to freshen up the air quality.

Function
• • Eliminate airborne allergens and germs such as pollen, dust mites, petdander, mold spores, bacteria, fungi and virus. • Freshen up the air quality.
