Yesido Ec39 Smart Air Purifier Pm2.5 Hepa Filter Digital Display Aromatherapy Assisted Air Purifier

Hello, there is 1 filter in the box, but there is no spare filter. The replacement filter needs to be researched and found online in general, as only one comes in the box, the replacement filter is not available in our store. If you use the filter inside at home, it will last for a long time, but if you plan to use it in a very dusty environment, it may last for a maximum of 3 to 6 months, but if you are going to use it at home, you can easily use it for more than 1 year, sir.
