Philips Respironics

The In-line Bacteria Filter is an additional filter to help allergy sufferers and would also be extra protection for people with infections or lung diseases.  They have a bacterial and viral efficiency of 99.9%.  The filter cleans the air as it leaves a CPAP, BiPAP or Ventilator machine before it enters the hose and mask, and is used along with the machine's built-in inlet filters to provide the cleanest air. 

It is a recommended CPAP supply compatible with almost all machines, and the average time people are using one filter is between 1 and 3 months, but it is easy to see when they need replacing through the clear filter cover as dirt will cause the filter to change from white to grey or black, and it is important to change them when this happens!  Some people will 'feel' when to replace them if their symptoms reappear (such as allergies, nasal congestion, wheeziness etc).

A single Filter can be purchased, or you can buy a Pack of 5, which is more cost-effective and also makes it easier to identify with a new one when to change the one in use by comparing the colour.

The In-line Bacteria Filter cannot be placed between the machine and the hose/tubing connection on machines which come with heated hoses, such as the Resmed's Climate Line Heated Tubing with the S9 and Airsense machines, Fisher & Paykel's Thermostat Heated Hose or the Respironics' own 60-series Heated Tubes.   In this case, the In-line Bacteria Filter could be placed between the hose and the mask, but bear in mind this will add weight at that connection.  However, the Bacteria Filter CAN be used with the Hybernite Heated Hose.

You will need a CPAP Hose Swivel Adapter for use with the Devilbiss Sleep Cube (Intellipap) Machine ONLY if you are using the fitted Heated Humidifier with your machine.


If you are using an APAP machine with automatic pressures which average out lower than 7 cm, please do not purchase these as they 'may' affect the airflow.

If the Bacteria Filter gets accidentally wet, allow the filter to dry before use.

Do not allow the filter to get too dirty before replacing with a new one, as this could affect the airflow.

You have to have these
Saturday, 4 August 2018  | 

I only started using my CPAP in May this year (2018) and was supplied one of these Allergy/Bacteria Filters by Philips with my machine. Although Philips supply the other little pre-filters FOC, for some reason they do not supply these. Since I became a diabetic in 2002, I've found I am susceptible to lots of allergies I never had a problem with before, so these post machine filters are a necessary item. Hope2Sleep are the cheapest on the net and a godsend for people with allergies.

So pleased to hear they're helping you.

Makes a difference

My husband and I both have asthma as well as sleep apnoea, and we got these filters to help our symptoms. Oddly enough, my filter turned grey and needed replacement after a month, while my husband's is still perfectly white! Our only guess is that it is due to his machine being near the bedroom window, so perhaps getting fresher air on the intake than mine does. In any case, neither of us will be without these filters again. Well worth it!

Must have addition

I use these with my Philips system one. I take it everywhere travelling. In one of the locations where I make extended visits, this filter is black after 4 weeks of use proving its effectiveness. I suffer slightly from Athsma as well so consider this filter vital.

The reviews of this product seemed positive and so because i have been suffering from sinus issues i decided to give them a go. I am so glad i did.
The difference in air quality is incredible. So much cleaner, noticeably so, and my sinus became to clear almost immediately.
What i really liked was the air quality, which i can only describe as being "soft". It was so much nicer to be breathing and the air pressure, while being maintained enough to register on my auto CPAP, made it easier to breathe. I really, really like this product and recommend it 100%. It is also great value for money.
Hope 2 Sleep were brilliant as well. Excellent communication during and after the purchase and super quick delivery. I will definitely be a returning customer because of the service and value for money compared to other sites. Very happy

anti bacterial filter
Tuesday, 7 February 2017  | 

Fitted the hose/mask well. Had to turn up the humidifier to prevent dryness which I think is to do with the filter capturing moisture. Filter itself has kept dry and there is reduced noise within the mask. Too early to determine the anti bacterial effect but there is marked improvement in comfort and quality of sleep.

I simply cannot survive CPAP without these filters
Sunday, 17 July 2016  | 

I simply cannot survive CPAP without these filters and I know when they need changing without looking at them because I can feel my allergy symptoms coming back. I just wish I had known about them a long time ago as my struggles with my mask would have been cut down. I highly recommend them for anyone with allergies A****

I consider the filters to be a worthwhile investment
Thursday, 9 June 2016  | 

Having used for one month the CPAP BACTERIAL FILTER (One) - For Allergy Sufferers. Here is my review and findings. I averaged 6.11 hours sleep per night according to the sleepyhead data readings for the period of use, which equates to 226.07 total filter hours. It certainly has reduced the amount of contaminated air that I would have been breathing had I not had the filter installed, which is surprising after only a months usage. I carried out a noise test with a DB meter on my Phillips System One RemStar Auto with A-Flex, with and without the Humidifier attached. In the intial ramp mode I found that with the humidifier attached there was insignificant reduction in the the noise level. With the humidifier detached the filter had the impact of reducing the noise by 3db. Comparison photographs can be seen in the forum at:- In my personal opinion I consider the filters to be a worthwhile investment and depending on the environment could probably be used for a lot longer that this months basic evaluation.
