Asking the right questions before placing an order can save time, reduce risk, and improve long-term cooperation. As a professional filtered shower head supplier, Leelongs knows what buyers care about most.
To help you evaluate us more efficiently, we have answered the most common pre-order questions below.
Q1: How do you prove the filtration performance of your filtered shower heads?
A: We can provide third-party test data and certification records of filtration performance. our shower filter was tested by SGS for free available chlorine reduction, and the report shows a removal rate above 99.47% throughout the tested service stages. This gives buyers a clear, data-based reference for evaluating actual filtration performance.
Q2: How long does the filter cartridge last?
A: The filter cartridge lifespan is influenced by the local water quality in your market and the type of filter media selected for the product. For example, water with heavier sediment, chlorine, or other impurities may shorten replacement cycles. Because of this, we usually recommend confirming your target market and intended filter material. We have more than 20 filter materials available, such as KDF, calcium sulfite pellets, coconut shell activated carbon, vitamin C pellets, blue antibacterial beads and anti-scale strips. Custom combinations are supported as you require.
Here are recommended products:
| Filtration Option | Customization Points | Corresponding Products |
| 10 / 15 / 20 Stage | Optional filtration stages, positioned as a universal multi-stage filter cartridge solution | LL-SF023 Universal Shower Head Filter Cartridge; LL-SF002 / LL-SF002B |
| 11-layer Composite Filtration | more suitable for a large-capacity standalone shower filter | LL-SF111 Large Capacity Multiple Filter Water Purification Filter |
| 12 Stages Filter | mainly for standalone shower filters or replacement cartridge applications | LL-SF017, LL-SF017K, LL-SF029 |
| 15-Stage Filter | A beauty-focused filtration solution integrated into the shower head designed for women | SH-30025 and its color variants: SH-30025G / GM / N / RG / K |
Q3: What water outlet modes are available?
A: The available spray patterns and water outlet modes depend on the product style you choose. Different models are designed for different user preferences and market needs. When you tell us your target customer group, we can recommend the most suitable filtered shower head style for your project.
- SH-2931(left): Recommended for buyers who want a premium multi-function filtered shower head with 9 spray modes, KDF chlorine filtration, and high-pressure performance. Ideal for customers seeking stronger product differentiation and better user experience.
- SH-2866(right): Recommended as a best-selling practical model with 5 spray modes, multi-layer filtration, and water-saving high-pressure design. A good option for home-use markets, retail, and volume sales.
Q4: Are the materials safe, and what is the main housing material?
A: The answer depends partly on the specific product model, because different styles may use different structural solutions. For our basic shower head housing, we use high-quality ABS made from new raw material, which helps ensure product quality and appearance consistency. There are several designs with stainless steel spray faces, such as SH-1540 and SH-1531. If you have specific market requirements for material compliance or safety, we can discuss the best option based on the product style you select.
Q5: Can the electroplated finish meet durability requirements?
A: Yes. The electroplating layer can be adjusted according to your product requirements, and we can also arrange salt spray testing if needed. Neutral salt spray testing uses standardized accelerated corrosion conditions to classify, compare, inspect, and validate the corrosion resistance of products. There are durations of 24, 48, 72, 96, and 200 hours. In general, the longer the test duration, the higher the required level of corrosion resistance. This is especially important if your market places high value on corrosion resistance, finish durability, or long-term surface appearance.
Q6: How do you ensure consistency between the approved sample and mass production?
A: During mass production, we use the same raw materials as the approved sample, so the bulk goods stay aligned with the sample standard. This helps reduce quality variation and makes the ordering process more predictable for our customers.
Q7: Can you support mandatory certifications and provide testing reports?
A: Yes, we can support product certifications based on your market and compliance requirements. If you need documentation, we can also provide the certification and testing reports. For customers selling into regulated channels, this can help simplify product approval and market entry.
The images provided show that we work with or hold documentation related to SGS, NSF, UPC, IAPMO R&T,WaterSense, CE, REACH, Intertek, Fsc, and lso 9001.

Q8: Do you offer custom packaging for bulk orders?
A: Yes, we support custom packaging, including custom color boxes. We can show you the color box styles we already support, and if you need another packaging format, we can customize that as well. When discussing packaging, we usually need to confirm two things first:
- Do you want us to create the packaging design for you?
- If you already have box artwork or technical drawings, can you send them to us?
Confirming these details early helps us move faster on sampling and production.
Q9: What are the production and shipping timelines?
A: The exact timeline needs to be confirmed based on your project details. Normally, we need to discuss the design confirmation schedule, sampling time, mass production cycle, logistics lead time, and whether split production or partial shipments are possible. We prefer to communicate these milestones clearly in advance, so both sides can plan the order smoothly.
Q10: What should I know about payment terms, after-sales service, and long-term cooperation?
A: These points are best discussed based on your order volume, product requirements, and cooperation model. For payment terms and payment methods, we will confirm the details with you during order negotiation.
For after-sales support, if the defective rate reaches the agreed standard, we can support return or replacement arrangements. Depending on the actual situation, our factory can also provide technical support. For long-term cooperation, we are open to discussing practical issues such as stable pricing, adjustments related to raw material fluctuations, and other commercial terms that help build a lasting partnership.
