Frequently Asked Questions (FAQ)

Getting Started

1. What does filters4u.com sell?

filters4u.com sells filtration products and media for industrial and paint applications, including pads, rolls, framed filters, and bags/cubes. Product availability varies by size, media type, and lead time.

2. Do I need an account to place an order?

An account may not be required for all purchases, but creating one can help you track orders, reuse shipping addresses, and streamline repeat ordering. If account creation is available, follow the prompts during checkout or via the account page.

3. How do I use the selection interface (EXHAUST/INTAKE, PADS/ROLLS/FRAMED/BAGS & CUBES, Poly/Glass/Channel)?

Use the interface to narrow options:

1. Select airflow zone: EXHAUST or INTAKE.
2. Select form factor: PADS, ROLLS, FRAMED, or BAGS & CUBES.
3. Select media: Poly, Glass, or Channel.

Before ordering, confirm your dimensions, quantity, and any facility requirements (airflow targets, change-out schedule, compliance constraints).

Product Selection

4. What is the difference between intake and exhaust filters?

Intake filters clean incoming air to reduce contamination and help protect finish quality. Exhaust filters capture overspray and particulates leaving the system to protect equipment and help maintain stable airflow. Exact selection depends on booth configuration, coatings used, airflow, and maintenance practices.

5. How do I choose between Pads, Rolls, Framed, and Bags & Cubes?

Selection is typically based on your equipment design and installation method:

• Pads are commonly used where media is placed in a pad format for replacement.
• Rolls are used when continuous media is required and cut-to-length workflows are preferred.
• Framed options are used when a rigid frame is required for fit or handling.
• Bags & Cubes are used when higher dust-holding capacity and 3D media structures are needed.

6. Can you match the filter I’m currently using?

Often yes. The fastest way is to provide:

• Existing part number (if available)
• Dimensions (Length × Width × Depth/Thickness)
• Airflow zone (intake/exhaust) and booth/equipment model
• Photos of labels and the installed location (helpful)

7. Do the counts/badges shown in the UI guarantee availability or lead time?

No. Counts and badges are informational and may not reflect real-time inventory, production capacity, or carrier conditions. Final availability and lead time are confirmed through checkout, quote confirmation, or invoice documentation.

Materials

8. What does “Poly” mean?

“Poly” generally refers to synthetic nonwoven media (commonly polyester-based). It is used across many industrial filtration use cases. Specific performance varies by product line and application conditions.

9. What does “Glass” mean?

“Glass” generally refers to fiberglass-based filtration media. It is used in various industrial filtration use cases. Specific performance varies by product line and application conditions.

10. What is “Channel™” media?

“Channel™” refers to a structured style of filtration media designed to manage loading behavior and airflow characteristics. Availability and recommended use vary by product line. Contact support if you need help confirming applicability.

Sizing & Fit

11. How do I measure filters correctly before ordering?

Measure the actual dimensions required for fit:

• Length and width across the face
• Depth/thickness (including frame depth if framed)

If you see “nominal size” on a label, verify whether the product runs slightly smaller (common in some product standards).

12. Do you offer custom sizes or cut-to-length options?

Custom sizes may be available depending on media type, thickness, and minimum order requirements. Provide the target dimensions, media type, quantity, and any constraints when requesting a quote.

Note: Custom or cut-to-size items may be non-returnable unless defective.

Ordering & Payment

13. Can I request a quote before ordering?

Yes. Quotes are recommended for large orders, recurring supply needs, custom sizing, or multi-location shipping. Provide size, media, quantity, and shipping destination(s).

14. What payment methods are accepted?

Accepted payment methods vary by site configuration and may include card payments and, for approved commercial customers, invoicing or net terms under a separate agreement.

15. Do you charge sales tax? What if I’m tax-exempt?

Sales tax may apply based on shipping destination and applicable law. If you are tax-exempt, contact support with documentation before placing urgent orders.

16. Can I submit purchase orders (POs)?

PO workflows may be available for commercial accounts or via the quote process. Include your PO requirements and billing contact details when requesting a quote.

Shipping & Delivery

17. How long does shipping take?

Transit times depend on stock status, manufacturing lead time (if applicable), carrier schedules, and destination. Estimated timing is communicated during checkout or quote confirmation.

18. Do you ship freight (LTL) for large orders?

Large orders may ship via freight depending on size and weight. If your facility requires liftgate service, appointment delivery, or has receiving restrictions, include those details when ordering or requesting a quote.

19. What should I do if my shipment arrives damaged?

Inspect shipments upon receipt. If there is damage:

1. Take photos of the product, packaging, and labels.
2. Note damage on the delivery receipt when possible.
3. Contact support promptly with your order number and documentation.
