#2. Hottest FAQs on Air Purifiers

You are invited to keep going this FAQ list! Your insights would indeed help others to make a smart purchase decision.

Q1. Can the Filter Just Be Washed and Reused?

How to clean air purifier HEPA filter?

Most of HEPA filters are not washable and used. You can use a DRY cloth to clean the appearance of the HEPA filter. Don't use the water to clean it which would damage the filter.

For the best air cleaning efficiency, it is advised to use a replacement HEPA filter, since new ones are always more qualified in removing the airborne particles than old ones.

Those so-called washable and reused HEPA filters are not effective to clean the air. Thus, for your personal health, always get a new HEPA filter.

Q2. How Often Do You Have to Change the Air Purifier Filters?

The frequency of changing air purifier filters depends on the volume of the dust, fume, and other airborne particles.

If there are a lot of dusts in your room, you may have to change the filter every 1 or 2 months.

If there is only a few fumes or smoke in your room, you just need to change the filter every 4 or 6 months.

Generally speaking, for the best air purifying efficiency, Purivortex experts suggest that you change the air purifier every 3-6 months.
