Request a Free Sample

Tell us what you need and our U.S. team will follow up within 1–2 business days. The fastest way to get a useful answer is to send the dimensions of your part — or a photo of the filter you use today. Photos are easiest over WhatsApp or by email.

Samples vs. Bulk Orders

Samples for our three hero product lines (cat litter, trash can & compost bin, and fan filters) are always free and ship from U.S. stock, typically within 3–5 business days. Shipping is not included and is confirmed per request. Bulk/production orders are manufactured and shipped from our factory in Nantong, China, on a normal cross-border timeline — a separate shipment from your sample.
