Mask Fit Insurance is available for this mask

If you are considering trying this mask for the first time, you can order in confidence using Mask Fit Insurance.

Mask Fit Insurance costs £14.99 for nasal masks and £19.99 for full face masks, and allows you to return this mask for a refund if unsuitable.

You have 28 days from the dispatch date to assess the mask and notify us that you are unhappy with it for any reason. You can return it and have it refunded (we must receive it back within 7 days of being notified).

The fee for the insurance is non-refundable once the mask is opened, as are any outgoing postage costs. The mask itself will be refunded in full.

A pre-paid returns label will be included for customers in the UK. We strongly recommend getting a proof of postage (which is free) as returns not received cannot be refunded. For overseas customers, the return postage will need to be arranged by the customer and this cannot be reimbursed.

CPAP masks purchased without insurance cannot be returned/refunded once opened for hygiene reasons, as explained in our returns policy.

Mask Fit Insurance must be ordered at the same time as the mask in question, and cannot be added retroactively.

Intus Healthcare reserve the right not to honour any orders containing multiple masks purchased with Insurance; please instead choose which mask you feel is most suitable and select the size required as per the sizing gauge (if applicable). Should you subsequently determine a different mask or size is required, you can of course return the first and order the other.

If you need any further information, please use the chat function (if available), or contact us.

How do I know which size of the Airfit N10 is right for me?

How do I keep my Airfit N10 clean on a regular basis?

It is recommended that you regularly wash your Airfit N10 in warm soapy water before and after usage to keep the mask clean. We would advise against using any antibacterial or bleach-based soaps as this can degrade the silicone cushion of the mask.

We also have CPAP mask wipes available for purchase that can be used daily to keep your mask clean, along with CPAP mask liners that will absorb skin oils and provide additional comfort while you use your mask.
