Return & Refund Policy

30-day returns on unused, unopened products. Straightforward refunds. Free returns when something arrives damaged or we make a mistake.

This Return & Refund Policy applies to all products purchased from enviromembranes.com, including our retail shop and B2B orders. In short: you have 30 days from delivery to return unused, unopened products in original packaging, and refunds go back to your original payment method within 5–10 business days of us receiving your return.

To start a return, email info@enviromembranes.com with your order number, or call (956) 843-0090.

Return Eligibility

30-Day Return Window

You may return eligible products within 30 days of the delivery date. Returns requested after 30 days cannot be accepted.

Condition Requirements

To qualify for a return, products must be unused, unopened, and in their original manufacturer packaging with all seals intact. Reverse osmosis membranes are precision-manufactured and sealed for preservation — once a membrane's packaging is opened, it cannot be restocked or resold.

Non-Returnable Items

The following are not eligible for return: opened or used products, custom orders, products purchased under special pricing arrangements, and products damaged after delivery due to improper storage or handling.

How to Start a Return

Step 1 — Request Authorization

All returns require prior written authorization. Email us at info@enviromembranes.com with your order number, the product(s) you wish to return, and the reason for the return. You may also call us at (956) 843-0090.

Step 2 — Receive Your RMA Number

If your return qualifies, we will issue a Return Merchandise Authorization (RMA) number along with the return shipping address and packing instructions. Returns shipped without an RMA number cannot be processed and may be refused.

Step 3 — Ship the Product Back

Pack the product securely in its original packaging, write the RMA number clearly on the outside of the box, and ship it to the address provided. We recommend using a trackable, insured shipping method — you are responsible for the product until it reaches us.

Refunds

Refund Method & Timing

Once we receive and inspect your return, we will issue your refund to the original payment method within 5–10 business days. You will receive an email confirmation when your refund has been processed. Depending on your bank or card issuer, it may take additional time for the funds to appear on your statement.

Restocking Fee

A restocking fee of up to 15% of the product price may be deducted from your refund on non-defective returns. The exact fee will be communicated to you when your RMA is issued, before you ship anything back. No restocking fee applies when the return is due to our error or a defective product.

Original Shipping Charges

Original shipping charges are non-refundable, except when the return is due to our error (wrong item shipped) or the product arrived damaged or defective.

Return Shipping Costs

Standard Returns

For standard returns — such as an unneeded product or an ordering mistake on your end — the customer is responsible for return shipping costs. RO membranes are heavy items, so we recommend comparing carrier rates before shipping.

Our Error or Defective Products

If we shipped you the wrong item, or your product arrived damaged or defective, Enviro Membranes covers all return shipping costs. We will provide a prepaid shipping label with your RMA.

Damaged or Defective Items

Report Within 7 Days

If your order arrives damaged in transit or a product is defective, notify us within 7 days of delivery at info@enviromembranes.com. Include your order number and photos of the damaged packaging and product — this lets us process your claim quickly and file with the carrier where applicable.

Free Replacement or Full Refund

For verified transit damage or defects, you choose: a free replacement shipped at no cost to you, or a full refund including original shipping charges. No restocking fee applies.

Warranty Claims

Manufacturer Warranty

Product defects that appear after the 30-day return window may be covered by the manufacturer's warranty. NanoH2O membranes carry manufacturer warranties as specified in the product documentation, and Enviro Membranes passes through all applicable manufacturer warranties. Warranty claims must be submitted in writing within the warranty period — contact us and we will guide you through the process.
