We do not just sell filters — we help you use the right one
Filtration is a category where choosing wrong costs far more than paying more. We run selection, supply, technical support and after-sales as one chain so procurement stops being a gamble.
Four steps, no back-and-forth
Requirement
Send a part number, machine model or photo of the old part; we verify dimensions, connection and seal.
Same daySelection & quote
We return matching numbers, alternatives, unit and volume pricing, with lead times.
1 business dayPick & dispatch
Stock ships same day; transferred items take 2–5 working days. Nominated carriers and export clearance supported.
Same day – 5 daysFollow-up
We check back after one service interval to confirm pressure drop, life and seal condition, and adjust if needed.

Ordering, lead time and warranty
01 What is the minimum order quantity? Can I mix part numbers?
One piece is enough for standard part numbers, and you can mix part numbers in a single order. Volume pricing applies from 50 pieces of one number, or above a single-order threshold. Fleets and resellers can work on an annual framework agreement with monthly settlement.
02 What is the lead time? Do you hold stock?
More than 3,000 fast-moving part numbers are held in stock and ship the same day if the order is confirmed before 16:00 on a working day. Non-stock numbers typically take 2–5 working days from the factory; custom items take 7–15 working days. Tell us at order time if it is urgent and we will prioritise it, with express or air freight if needed.
03 What if there is a quality problem? Is there a warranty?
The full FILTERSUN range carries product liability insurance from CPIC and a three-guarantee quality commitment. If a genuine manufacturing defect is confirmed we replace or refund it and cover freight both ways. Keep the original packaging and batch label — it makes claims and traceability much faster.
04 Can you export? Do you provide customs documents and English packaging?
Yes. We work on FOB, CIF and DDP terms, provide commercial invoices, packing lists and certificates of origin, and can supply neutral or English-language packaging. We settle in RMB, USD and other currencies and have shipped to more than 70 countries and regions.
05 Can you make custom or non-standard filters?
Yes. Send a drawing, a sample or the key dimensions — outside diameter, inside diameter, height, connection type, micron rating, media and working temperature. Standard custom builds take 7–15 working days; tooling required for moulded parts is quoted separately. Small batches are welcome.
06 Can I get a sample or a small trial order?
Yes. Common numbers can be supplied singly as samples. Before a bulk order we recommend trialling one or two machines over a full service interval and checking restriction, pressure drop, media strength and seal condition. We are confident in the product and welcome that kind of verification.
