How Do Air Purifiers Work
How Do Air Purifiers Work
An air purifier is a portable machine used inside the room that cleans the air with a filter. It use an internal fan to suck air into the machine and traps pollutants inside the filters as air passes through it.
The level of air pollutants inside the room are often 3-5 times higher than outdoor levels. The airborne contaminants includes things like dust, pollen, pet dander, mould spores, smoke particles and volatile organic compounds (VOCs) and dust mite feces can act as allergens, triggering allergies in sensitive people, such as asthmatics.
What Does HEPA Mean
High-efficiency particulate air (HEPA), also known as high-efficiency particulate absorbing is an efficiency standard of air filter. Capture from pollen sized down to virus and smoke sized particles.
HEPA filter is constructed of special microfibres in the form of pleated sheet which direct airflow through the filter, then increase the overall filtration surface area. HEPA filters are used in applications that require contamination control, such as the manufacturing of medical devices, nuclear, food and pharmaceutical products, as well as in hospitals, homes and vehicles.
How You Benefit from Our Air Purifiers with HEPA Filter
Compare to a regular filter that only captures large dust particles,
Our Basic 3 Stages Filter
- Pre-Filter: Captures most of the large dust particles, pet dander, hair, PM10 and pollen particles from the air.
- HEPA filter: Filters out the finer particles that escapes from the pre-filter. Traps 99.7% of harmful micron-size particles and 0.3 micron dust allergens and viruses.
- Activated Carbon Filter: Absorbs and deodorizes household odours, lingering smells from cooking, Tabaco smoke, wet pets smell.
A HEPA filter can be used in conjunction with a pre-filter and activated carbon filter to extend the usage life of the more expensive HEPA filter
Other Functions We Used in Our Air Purifiers
- Ultraviolet germicidal: Use short-wavelength ultraviolet (UV-C) light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their DNA, leaving them unable to perform vital cellular functions. It can be used in a variety of applications, such as food, air, and water purification.
- Negative Ions: Diffuse and break down airborne microbes like allergens, bacteria, mould and viruses. Clear the air of pollution and floating contaminants.
- UV + Photocatalyst Filter: Photocatalyst filter reacts with the UV to destroy airborne contaminants and disintegrate harmful substance into harmless substance. Provide a fresh indoor air condition by sterilizing germs and removing odours.
