High Quality Small Volume HEPA Filter Air Cleaner Suitable for Room Air Purification

Negative ions in negative ion air purifiers can combine with tiny particles in the air, causing them to settle and purify the air; Meanwhile, negative ions also have certain benefits for human health. Zero noise, low energy consumption: no fan design, no noise generated during operation, and low energy consumption. Due to the complexity of technology, the price of negative ion air purifiers is usually higher.

Physical air purifiers use high-efficiency filtering materials such as HEPA filters, which can effectively remove large and small particles such as dust, pollen, and bacteria from the air. The physical filtration method is mature and stable, and is not prone to secondary pollution. But the filter needs to be cleaned or replaced regularly, which increases the cost of use. Some products may produce significant noise during high-speed operation.
