Refunds and Returns

Last updated 14 September 2026. This page describes how this shop works in plain English. It is not legal advice.

Faulty, damaged or not as described

If something we sell you arrives faulty, damaged or not as described, we put it right: a repair, a replacement or a refund, and we pay the return shipping. That is our promise, and it sits alongside your rights under the consumer protection and warranty laws of your state, which vary from state to state and which nothing on this page limits.

Email theteam@co2monitor.store with your order number and a short description of the problem. If something arrived broken, a photograph of the item and the packaging helps us take it up with the carrier, but it is not a condition of putting it right.

Changed your mind? Our own 15 day policy

There is no general federal right to cancel an online purchase in the United States, and we would rather be straight about that than imply a right you do not have. The FTC's Cooling-Off Rule gives three days to cancel certain sales made at your home or at a temporary location; it does not cover orders placed online. Some states have their own rules for particular kinds of sale, and where one applies to you it applies whatever this page says.

What we do offer, as our own policy, is 15 days from the date of purchase to change your mind. Email us within those 15 days, send the goods back unused, in their original packaging and with your order confirmation, and we refund what you paid for them less a $29 packing and handling fee per order. You pay the return shipping, and the goods go back to the warehouse they were sent from. This applies to a better price found elsewhere, a change of mind, something that does not suit, something no longer needed, or the wrong item ordered.

Face masks and face shields are worn against the face, so we can only take those back unopened and unused.

We cannot accept returns of items bought from a third party retailer.

Cancelling an order

Any order can be cancelled until it is dispatched. Most orders are packed within 24 hours, so tell us within 12 hours if you can. A cancellation after payment carries a 12.5% service and processing fee. Once packing and shipping has started the order can no longer be cancelled, and the returns policy above applies instead.

If we cannot ship on time

If we cannot ship your order within the time we have told you, we let you know before that time runs out and give you the choice of waiting or cancelling for a prompt, full refund. A cancellation in that situation carries no fee.

Damaged in transit

If a parcel arrives damaged, email us with your order number and a photograph of the packaging and the item. We arrange a replacement or a refund and we cover the return shipping.

Missing items or the wrong thing sent

Tell us and we fix it. If the parcel never arrives, arrives with parts missing, or contains something you did not order, that is ours to resolve and it costs you nothing.

How to return something

Email theteam@co2monitor.store with your order number and what you would like to do. We reply with the return address and confirm who pays the shipping in your case. Please contact us before sending anything back, so it reaches the right warehouse and is credited to your order.

We process refunds within 24 to 48 hours of the goods arriving back. Card issuers and PayPal usually take a few further business days to show the money on your statement. Refunds go to the payment method you used, or can be held as credit against a future order if you would rather.

If we cannot agree

Email theteam@co2monitor.store with your order number and the word "complaint" in the subject, and a person will look at it again from the start. If we still cannot resolve it, you can take a claim to the small claims court in your state, or contact your state attorney general's consumer protection office. Nothing on this page affects your rights under the consumer protection and warranty laws of your state or under the Federal Trade Commission Act.
