Filthguard, air filter that traps PM 2.5 and various airborne micro-organisms, can be used with all air-conditioners.

Living a healthy life begins with the pure air. Indoor air pollution can be worse than outdoor up to 2-5 times. The pollutants, allergens, pathogens and viruses may slip through normal air conditioning filter. Causing the air that has a lot of pollution becomes the air that is closest to us.

PM2.5, a dust particle with diameter of 2.5 microns, small enough to remain floating in the air and may easily get inside your lungs. The PM2.5 and other forms of small particles, such as, fog, smoke, bacteria and dust mites may cause allergic reaction or stronger attack of Asthma. Long term exposure to these particles may lead to a heart disease and deterioration of lung function.

Instead of having to spend a lot of money buying a high quality and expensive air-purifier, you can alternatively choose to transform your air-conditioner at home to perform the tasks, producing a safe quality clean air, just as effectively as a high quality air-purifier, simply by installing De Hygienique’s “Filthguard” air cleaning filter which is compatible and can be used with all air-conditioning system, by means to reinforce the filtering performance and ability of the air-conditioner.

Filthguard is made from PTFE fiber, commonly used for HEPA (High efficiency particulate air) filtering, with an electrostatic behaviour that makes it capable of trapping tiny particles that cannot be seen with normal eyes, such as, bacteria, virus, PM2.5, and allergens, the main cause of various respiratory illness, i.e. Asthma.

ได้รับการแนะนำมาจากเพื่อนอีกที หลังจากใช้มาซักระยะ ไม่อยากเชื่อสายตาตัวเอง ตอนที่ถอดแผ่นกรองออกมาทำความสะอาด จากแผ่นกรองสีขาวกลายเป็นสีเทาเข้มๆ ฝุ่นระเอียดเกาะที่แผ่นกรองแน่นมากค่ะ
ใช้อยู่ เดือนนึงเปลี่ยนที จะเห็นชัดว่า ฝุ่นเยอะมาก ผมว่าควรใช้นะ ฝุ่นจะเข้าแอร์น้อยลงมากๆ
สำหรับผม ถ้าจะล้างแอร์ที งานช้ามากๆ เพราะบ้านที่อยู่ตอนนี้ออกแบบและสร้างตามใจ หลายๆอย่างไม่ถูกหลักนัก โดยเฉพาะจุดติดแอร์ ผมว่าแผ่นกรองตัวนี้ตอบโจทย์ได้ดี

Our customers asked us these questions most of the time 🙂

For maximum efficiency, we recommend to change filters every month. Filthguard filters are designed and tested under a variety of operating conditions. However, there are some reasons that you may need to change filters more often such as the construction in progress, while polishing furniture or walling, and have pets. Therefore, the filter should be changed regularly.

Filthguard is designed to allows the air to flow smoothly and consistently without affecting the cooling system. But if the filter has been used for longer than the recommended age, air flow may begin to be limited, which may cause the cooling system to malfunction.

One roll of up to 15×96 inches that can be used with all brands air conditioner just cut the filter to be the size of the original air filter.
