Hello,

I am interested in your air filter products and would like to ask for more details. I run a small online thrifting store from my home, and I want to improve the air quality in the room where I store and prepare clothes, so that there is less dust and the items stay fresh for customers.

Could you please recommend which type of air filter is suitable for a small room in a house, and let me know the approximate price, size options, and how often the filter should be changed? If you have any brochures or product information, I would be grateful if you could share them.

Thank you very much for your assistance
