This is the S.Box Heated Humidifier which attaches to the S.Box CPAP Machine by removing the side cover. It will not work with any other manufacturer's CPAP machine. 

CPAP and Ventilation Humidifiers are very helpful, and often a necessity, when people suffer from a dry mouth and nose, nasal irritation and allergies etc, and the heated humidity helps address these problems and can make a huge difference to patients therapy by eliminating the discomfort the cold air can cause.

The S.Box Heated Humidifier for when dry mouth and/or nose is experienced, and humidifiers also help with sinus issues, nasal drip, nose bleeds and cracked lips.

The S.Box Heated Humid Control+ enables humidification without condensation, taking into account the ambient temperature as well as the average flow rate.

The Humidifier has 10 adjustable settings to increase or decrease the amount of humidification needed, which varies from season to season.

The Humidifier attaches to the S.Box by removing the side end piece from the CPAP and the Humidifier Chamber is easy to fill with water and clean. 

There is also an optional Heated Hose with ATC (Adaptive Thermo Control).

Heated Humidifier and Heated Hose


  • When the Humidifier Chamber is new it can be stiff to open with the hands, but will easily open with the use of a pen or similar (see the video below). 
  • Any unused water should be discarded every morning, as it is a perfect breeding ground for germs and bacteria and mould can form. The humidifier should also be rinsed out daily and at least once a week given a deeper wash.
  • Distilled Water is better to use as there will be no build up of minerals and limescale in the humidifier chamber which will need more thorough cleaning, but it is difficult to find in the UK and expensive. However, if the water is safe to drink then it is safe to use in the humidifier. (It just means that using tap or mineral water will require more rigorous cleaning of the humidifier chamber).
  • NEVER use Deionised Water in the humidifier as it is unsafe for respiratory equipment.
  • NEVER place anything except water inside the humidifier, such as menthol crystals or aromatherapy oil etc, which will damage the humidifier and the machine, and is not medically safe.

We try our best to ship all orders received by us Monday-Friday on the same working day if received before 12 noon, and more often than not orders processed before 3pm will be despatched the same day whenever possible.  Weekend or UK bank holiday orders are sent out the next working day.  An automated email is sent when products have been despatched so please check your spam box and add us to your safe senders list.  Also, if you do not receive an email confirmation, please check that you have typed the correct email address in your account.

All orders are sent via 1st class mail within the UK.  Masks and some other more expensive products are always sent via 'signed for' insured delivery and cannot be left in 'safe' places, but there is the option for an alternative shipping address when processing the orders. 

Delivery charges are worked out automatically by weight and you can clearly see the delivery charges before making a payment.  On the rare occasion delivery charges are miscalculated by the website, a refund will be sent, as it is not our policy to make money on postage charges and neither do we add the cost of delivery into the price and offer so-called  'free delivery' like some sites and Ebay pressurise sellers to do! 

Wherever possible with larger parcels, we try to re-use boxes to keep shipping costs down and protect the environment.

If a product is out of stock and the order contains multiple items, the 'in stock' items will be sent immediately and further items will follow upon arrival with no further postage charges incurred.  

Important for International Orders

We can ship most products internationally, but all prices are in UK British Pounds and if paying by debit or credit card the bank will automatically convert to the current conversation rate.  Likewise, if you choose the Paypal option, they will convert into your currency for you as payment is made.  

International orders are sent via tracked Airmail, and whilst we're happy to ship internationally, we cannot be held responsible for any delays at Customs at your end, or charges that may be added in your own country, such as customs fees and import tax on delivery, which are determined by your country’s import laws and are beyond our control. Therefore, it is the customer’s responsibility to pay these charges, and certain courier companies will not be able to deliver the goods to you without pre-payment of any charges. From our experience, it appears to be randomised as to which parcels incur extra charges, but please know that all accompanying paperwork is filled in correctly when shipping and there is nothing more we can do, as much as we'd like to.

If you purchase from us out of the UK or you move to another country after purchasing products, please be aware that the warranty for CPAP machines, masks and parts from the manufacturers are under warranty  with the manufacturer based in the UK, so you will be responsible for sending the product back to us and will need to pay postage to get the product back to you after exchange or repair, as the manufacturer will not pay for shipping in any country outside of the UK.


Masks, CPAP machines and and most other products are exempt from a refund or exchange unless faulty due to health and hygiene issues - as stated in our 'Terms and Conditions', and in particular due to the risk of cross contamination as they cannot be re-sold. The Consumer Contracts Regulations 28.(3)(a) confirms exemption as follows:-  "exemption in the case of a contract for the supply of sealed goods which are not suitable for return due to health protection or hygiene reasons, if they become unsealed after delivery."

Unopened (sealed) products in their original packing can be returned within 14 days for a refund of the product cost, but the purchaser is to pay the return postage, and we would advise retaining proof of postage. This excludes any faulty goods, for which postage will be reimbursed.  A full refund for the price of the product will be issued when received by us, less the original postage charges when the order was sent to you.



Most of the products we sell are eligible for Zero Rated VAT in the UK, and in order to qualify, you should meet the criteria for the following HMRC VAT Declaration:-

  1. You or the person you are purchasing on behalf of have "a condition that the medical profession treats as a chronic sickness, that is a long term health condition" (sleep apnoea and sleep disordered breathing, which require therapy, are such conditions).
  2. "The goods or services are for the personal or domestic use of the customer."

Please note, you do not need to be registered as disabled or in receipt of any other benefits in order to be eligible for VAT relief - you only need to meet the criteria of the above 2 points.

We cannot advise on individual cases, but more information can be found on HMRC’s website under notice 701/7 on the following link  https://www.gov.uk/government/publications/vat-notice-7017-vat-reliefs-for-disabled-people

If you are not eligible for Zero Rated VAT then please make sure that the VAT Relief box in unticked so that VAT is applied to the order.

If you are purchasing on behalf of someone else who meets the above criteria, you must provide their name and address, and you will be prompted of this during the checkout process.

Customers living outside of the UK do not pay UK VAT charges, so please leave the the VAT Relief box ticked.  However, we cannot be held responsible for any additional costs incurred when the products reach your own country.

If you are purchasing with the intention of re-selling any products, you are liable to pay VAT on all products so you must untick the 'zero rate eligibility' box which will add VAT to your order.

Any products that our not eligible for zero rate VAT, will not display the VAT Declaration, and VAT will be added at checkout.
