Lowenstein Medical

These are the top of the range Prisma SMARTmax APAP (auto pressures) and SOFTmax CPAP (fixed pressure) machines by Lowenstein Medical, and we are pleased to be an official UK distributor of their high quality range of CPAP machines, masks and accessories, as they are very supportive of our charity.

These are the top of the range Prisma SmartMax APAP (automatic pressures) and Prisma SoftMax CPAP (fixed pressure) machines by Lowenstein Medical (previously known as Weinmann) who are a quality German manufacturer of CPAP, anaesthesia workstations, neonatal ventilators, ICU-ventilators, sleep diagnostics and high quality masks (also available on our website). Lowenstein do have a big range of different CPAP and non-invasive ventilator models and it is these 'max' series which are the white machines in the Prisma line.

For ease of understanding the difference between the machines, the 'SMART' relates to the APAP machines (which means they operate at auto pressures, depending on a patient's need to treat 'automatically' and the 'SOFT' is referring to fixed CPAP pressures which need to be set via monitoring/titration by a sleep consultant or sleep clinician. Both machines look identical with just the different names printed (Prisma Smart or Prisma Soft).


CPAP and APAP Therapy with Fully Integrated Connectivity

Both the Prisma SoftMax (CPAP) and Prisma SmartMax (APAP) have modern, reliable CPAP and/or APAP therapy featuring integrated connectivity with diverse interfaces (SD, PSG, LAN, internal Bluetooth, internal modem), precise event detection and a high level of patient comfort. (The Prisma SoftMax can only be run at fixed CPAP pressures, but the Prisma SmartMax is mainly run on automatic pressures, but has the option to run on fixed CPAP mode as well).

Both machines have integrated Bluetooth for data transmission to the Prisma APP and thus for modern patient self-management which is available for both IOS and Android.

I was happy with the Philips, but only because I had nothing to compare it to. This is so quiet. Autostart is very useful. If switched off for whatever reason, it will shortly automatically start. App is superb and tells you your deep sleep. In my opinion an important statistic, as AHI doesn't tell you if you have has effective sleep. Better features than my friend's SleepStyle.

Replacement for Philips DreamStation Auto CPAP
Wednesday, 9 March 2022  | 

I purchased the Lowenstein PrismaSmart APAP (LPS) to replace the Philips DreamStation (PDS) following the recall of the PDS product. It is not as elegant as the PDS, it is more bulky and triangular rather than the 'clock radio' look of the Philips. Also, the pipe feeds out from the front which just looks ugly. The LPS is much quieter and more responsive than the PDS. I cost me around 100 more. The travel case is not as smart either. So overall, it is a good functional replacement but scores lower on looks. They both use 15mm pipes, so I continue to use the same Philips nasal mask with the LPS which works fine.

Looks are very individual as I personally like the triangular shape 😊 Good that you're on a safe machine now though and hope you're finding it whisper quiet like most people say.

Excellent machine

A very quiet machine. It was recommended and I totally agree.

You're definitely right about it being one of the quietest CPAP machines we've come across.



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 charges that may be added in your own country.

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 which the medical profession treats as a chronic sickness," (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."

We cannot advise on individual cases, but more information can be found on HMRC’s website under notice 701/7 on the following link

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.
