Common questions

Is the HEPA filter washable?

HEPA filters cannot be cleaned after their capacity is exhausted, even if they are washed.

How often should the HEPA filter be replaced in air purifiers?

The time to change air filters is different. This time efficiency is directly related to the filter capacity. Our suggestion is to choose a device whose HEPA filter needs to be replaced every one to two years.

Is the HEPA filter able to remove unpleasant gases and odors?

A HEPA filter is usually effective at removing solid particles in the air, but cannot remove gases and unpleasant odors. To remove unpleasant odors, it is better to use active carbon filters.

Does the HEPA filter perform differently depending on the class?

Yes, different classes of HEPA filters have different criteria for filtration efficiency. For example, class H13 and H14 HEPA filters are more effective at removing smaller particles such as viruses and bacteria than lower classes such as H11 or H12.

Do devices that use a HEPA filter use more energy?

Yes, in general devices that use a HEPA filter require more power, but the difference in energy consumption depends on the technology and design of the device.
