Which Small Air Purifier Can Filter VOCs?
Small air purifiers that can filter out volatile organic compounds (VOCs) typically require one or a combination of two core filtration technologies:
1. Activated Carbon Filter
• Working principle: Activated carbon has a porous structure and can capture and remove VOCs in the air through adsorption, such as formaldehyde, benzene and other chemical pollutants.
• Applicable scenarios: Suitable for use in newly renovated rooms or environments with chemical odors.
2. • Photocatalytic Oxidation (PCO)
• Working principle: Using ultraviolet light (UV) and titanium dioxide catalyst to interact, VOCs are oxidized and decomposed into harmless carbon dioxide and water.
• Advantages: No need to frequently replace filters, can continuously decompose pollutants.
Recommended small air purifier types:
1. Portable purifiers with activated carbon:
o Suitable for use in the bedroom, desk or car.
o Such as: Blueair Blue Pure series, LEVOIT Core Mini.
2. Composite purifier with photocatalysis and activated carbon:
o Combining multiple technologies, it can efficiently decompose and remove VOCs.
o Such as: Dyson Pure Cool series, IQAir Atem series.
3. Purifiers using PECO technology (photoelectrochemical oxidation):
o More efficient than traditional photocatalytic technology.
o Representative brand: Molekule Air Mini.
Things to note when purchasing:
1. The clean air output (CADR) of the purifier: Choose a CADR value that is suitable for the size of the room.
2. Filter replacement frequency and cost: Activated carbon filters need to be replaced regularly, so understand their maintenance costs.
3. Noise and power consumption: Choose a device with a low noise design for easy daily use.
