AG Industries

These are the Filters for the the Philips Respironics' Legacy REMstar (Pre M-Series) CPAP + BiPAP Machines, but they are NOT made by Philips Respironics, as they have discontinued these filters now so we have sourced them from AG Industries.

These are compatible Filters for use with the Legacy REMstar (Pre M-Series) CPAP + BiPAP Philips Respironics' Machines.  

There are 2 types of Filters as follows:-

White UltraFine Filters x 6

The UltraFine Filter prevents pollen and other small particles from entering your device, and it is very important to use these, especially if you are susceptible to allergies, asthma and sinus issues etc.

Philips Respironics recommend changing these filters every 30 nights of use, or sooner if they becomes dirty.  Please note that you must not clean these filters - they need to be discarded and replaced. 

To fit them ensure the mesh side of the filter is facing in, towards the machine.   (If you are using the black foam filter this is placed on top of this white one).

6 Filters are supplied.

Foam Filters x 2

Legacy CPAP Foam Filters - Philips Respironics

This is the Grey/Black Foam Filter for the Legacy REMstar (Pre M-Series) CPAP/BiPAP Philips Respironics Machines. It will not fit M-Series or System One Machines.

It is vital for the machine and your own health that, as recommended by Philips Respironics, you clean this dust filter at least every two weeks and completely replace it every six months.

2 Filters are supplied.


These filters are made by AG Industries as Philips Respironics have now discontinued them!

The machines pictured above are for illustration only, to help you identify which machine you are using, as to which filters are required.

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 3 pm 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.   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.

Delivery charges are worked out automatically by weight and you can clearly see the delivery charges before purchase.  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.  


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 Europe, 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 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 Europe do not pay UK VAT charges, so please leave the the 'zero rate eligibility' 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.
