Hello JK Green Products team,

My name is Alex. I run a small online vintage clothing and secondhand shop, and I use air conditioners and air filtration quite a lot at home and in my storage space, so I’ve started to pay more attention to air filters.

I’d like to ask for some advice

Which JK Green air filters are suitable for homes, small offices, or small storage areas, and how often should they be replaced to stay safe and cost‑effective?

Are there any simple signs to know its time to change the filter, even if it hasn’t reached the recommended replacement period yet?

If I want to reduce dust, musty smells, and help keep stored vintage clothing from developing unpleasant odors, which type or model of filter would you recommend?

If you have product information links, user guides, or care instructions, I’d really appreciate it. This would help me choose the right filters, protect my equipment, and maintain cleaner air for both my living space and my vintage clothing inventory. Thank you very much.
