With viral and bacterial filtration efficiencies of over 99.99+% each Universal Inline Bacterial Viral Filter for CPAP/BiPAP Therapy comes complete with holders as shown! Hudson's filter technology helps stop the viruses and bacteria that often plague CPAP/BiPAP users creating a clean, sterile environment for airflow.
The Inline Bacterial Viral Filter is easy to install and should not require re-calibration on most CPAP machines including those from Respironics, ResMed, Fisher & Paykel, Puritan Bennett, and DeVilbiss. Simply attach it to your machine between the air outlet and your standard CPAP/BiPAP tubing. After that, turn on your machine and experience a steady flow of clean, pure, good tasting air.
The Inline Bacterial Viral Filter's naturally hydrophobic filter allows maximum filtration with a minimum loss of air flow.
Usage Information: Bacterial Viral filters last on average 4-6 weeks however your filters may last longer or shorter. In general BV filters should be changed whenever the filter material looks dirty.
Usage Notes: Some users find that using In-Line Bacterial Viral Filters can reduce pressure and therapy effectiveness in humidified CPAP/BiPAP machines. Use of Inline Bacterial Viral filters may adversely effect auto sensing on Auto-CPAP machines especially at low pressures (below 7cm).
Very easy to hook up in line and priced right. Makes me feel safer when using my cpap Written by wfvaii-55961, 2018-12-02
I have severe allergies to various environmental dusts and dust mites. Too much was getting by the filter on my CPAP. The In-Line Bacterial Viral Filter is a great solution. I place it on the end of the hose coming from my CPAP machine. It doe not interfere with my sleep. I just change it monthly when I change my CPAP filter. Written by davezinnc, 2018-11-18
I sleep much better and longer. I wake feeling better than before. Sinuses don’t feel irritated nor stuffy. Written by dena62145, 2018-10-27
I have horrible allergies and was experiencing sore throats when waking up. This doesn’t happen very often while using the in-line filter. Only downfall I find as a side sleeper is the filter is bulky and the hard plastic container has clunked me a few times. Also holds a lot of water/condensation within the plastic case.

I have always had a good experience with every facet of my order Written by jimrussellkcle, 2018-09-10
Excellent product. I feel very safe using it Written by MYCIN17, 2018-08-17
This product is not the same quality as others I have purchased. Written by alohacg, 2018-08-10
I can tell the difference in air quality when using this filter. At home, I usually change it every month. However, when I'm traveling, sometimes I find myself in environments with poorer air quality. I recently went to Nicaragua and my filter turned brown and had to be replaced after only 10 days! Written by daoki-304, 2018-05-11
This product is not talked about by the regular supply people. Found this by accident, tried it and have noticed drastic changes in my response to allergens and don't have the throat problems in the morning. will definitely be remaining a customer/user of this product. Will recommend to anyone that uses the therapy. Written by wbh2012, 2018-04-03
For a number of years now, I've been using the In-line bacterial viral filter in addition to the regular filters and I think it works fine. Written by ssgsaf, 2018-03-29
Very pleased with the product and fast delivery! Written by yaritzabarreto, 2018-02-15

I am so happy that I found these filters! I am anxious to be how much they reduce the stuffy head my husband gets. Written by biggs4, 2018-01-15
Happy to have these. Should have got them long ago but never knew about these! Written by mdav911, 2017-12-04
Fast delivery and great price Written by martyschalk, 2017-11-20
Buy them in multiples. I change mine every 10 days Written by CINNDREW, 2017-11-15
Great product... Great price....fast free shipping... What's not to like? Written by SNOWCAT1211, 2017-11-07
I ordered this for my husband’s cpap machine. His old filter was quite dirty and I didn’t realize how dirty until I received this one. I was reading that these should be changed on a more regular basis. We will from now on. Very satisfied with the buying process as well. Written by jr314421, 2017-11-05
Great idea. I put it between heated hose and hose to mask. It has a smell when mask is first used but goes away after first few minutes. Written by djvalentine123, 2017-11-05
Nice and clean experience Written by PearlAquaVole, 2017-10-26
It catches a lot of dust at and dirt that would otherwise had breathed in. Written by wpresley464, 2017-10-26
These filters remove a lot more from the air stream than the little filter in the machine. I have not noticed any change in the pressure of the air, so win-win. Written by beckare, 2017-10-22
I could tell a difference after one night. Written by chermdane, 2017-10-17
Fulfilling the order was no problem. The filter appears to work, however, I've found no guidance as to how often the filter needs to be replaced. In other words, what signs do you need to look for that indicate that you are ready for a new filter. I changed the filter when the discoloration was obvious (on the tank side, not the hose side)...but I can only wonder if the filter should be changed more often or not. It would be nice if the retailer and/or the manufacturer would provide some guidance in this area. If there were clear guidance, I would give this product 5 stars! Written by a4j2425, 2017-10-05
These filters have created more problems than solved. Cause a moisture backup, a constant gurgling sound and restricts flow. So our take on this is while they are relatively inexpensive they just don't do what we hoped they would Written by nicktcasper, 2017-09-27
No problems . Seems to wrk fine with my ResMed AirSence 10. Written by revadakin, 2017-08-13
Good experience. Catches a lot of dirt and bacteria that would otherwise gone into the breathing mask. Written by bridgecreekimages, 2017-08-04
Took me awhile to figure out where to attach it using a heated hose. I just put it on the mask hose. I hope it truly helps with bacteria. Written by PaleGoldenrodCobra, 2017-04-20
Performs as expected. I will reorder. Would recommend to friends. Order from cpap exchange was delivered much faster than i expected. Written by TitaniumYellowMouse, 2017-04-05
Works exactly as described, and great customer service! I will definitely shop at cpapXchange.com again. I wish I didn't have to write 20 words about it though. Written by paul_oreilly, 2017-02-20
I believe I am happier with my c pap since adding this filter. Written by Harold , 2016-12-28
I've been getting the bacterial filters from CPAP EXCHANGE for over four years (plus other items). The company is wonderful to deal with and their products always arrive in time and in excellent condition. I HIGHLY recommend this company to anyone who needs cpap products. Written by Barry, 2016-12-21
works great, easy to install. After a few days you start to see the dust etc.. that it traps. Love it Written by mike V, 2016-12-19
better than expected Written by h24trapman, 2016-12-16
Ordering my product was easy online. The discounts were applied automatically and the site was user friendly. My purchase was delivered on time. Written by Juan B., 2016-11-07
Filter works well, although it appears to bring down the airflow a little. I therefore changed my settings by one point to compensate for that loss. Written by Victor R F, 2016-09-27
Extra to make sure air flow is safe. Written by Larry , 2016-09-15
These inexpensive virus filters are the best and have kept me from getting a cold or the flu for a couple of years now. I used to get sick quite often till I started using these filters. They turn black after a month or so from catching all the junk that would go into your lungs without it. Easy to install between bipap outlet and hose, no tools needed. Highly recommended. Written by Matthew, 2016-08-07
I searched on internet for a filter, and found this one and at been the best thing I could have done. Before getting the In-line Bacterial Viral Filter, my wife would get a virus infection once a month. I'm glad to say she has virus free for the past month. Wish her doctor or cpac supplier had told us there was this filter. Written by David, 2016-08-04
good job Written by J.C., 2016-07-18
The first night the filter worked fine with ResMed Auto with Humidifier. The second night I felt like I could not breath. There was also a lot of condisation in the hose and nasal pillow. I had to take the filter off the machine. I would like to try the filter again and see if it works better. Written by kadyar, 2016-02-27
It's good to use. However, its very easy to have condensation in the cold night and make breath very difficult. Written by Yen-Chywan L, 2015-12-09
I decided after a few nights to remove the filter. Needed more air flow. Written by Skip T, 2015-11-20
These filters retain so much moisture from the humidifier that by morning, the filters are soaked and the oblong filter chamber is filled with condensate. The wet filters can develop mold and mildew bacteria trading one contaminant for another. I think the filters interfere with the auto humidification systems in my Auto-CPAP machine. Written by Larry A, 2015-09-21
Bought these to help with some allergies and it occluded the air so badly is was like sucking air through a straw. Written by Jo, 2015-07-31
These filters greatly increase the cleanliness of the air being delivered to you. They do not affect machine pressure settings or other functions. They seem to last for several months. I've been using these filters for many years and highly recommend them. Written by John, 2015-07-14
great product and service Written by claude, 2015-07-03
I was practically unable to use my machine because of allergies. The first night I used this I slept wonderfully and have had no problems since! Wonderful Product and answer to my problems! Written by D. Lee, 2015-05-29
I use a CPAP ResMed S9 Auto and this filter I could see how much dirt is in the air we breathe, as the filter gets dirty in a few days. How do I use also a Eson mask, I noticed that the diffuser mask has become much cleaner time. I installed the filter on the outlet air humidifier H5 and the trachea connected to it, so I consego the air that goes into the hose reaches my nose clean and free of impurities. When I use the CPAP without this filter immediately notice an irritation and a feeling that the air I'm breathing is dusty. It is an excellent product and very important for my health. Written by Marcélio, 2015-05-26
To have an extra fine filter in the line seemed to a be good idea until I tried them. They partially defeat the A-Flex operation of the cpap machine. When I exhale there is still a incoming pressure to fight. Without the filter there is no back pressure to fight. Written by Paul D, 2015-04-07
Excellent product. I felt better the first day after using it. Written by Ken W, 2015-03-30
These little in-line filters trap everything that the foam filter misses. Great for allergy sufferers. Also, if you do aroma therapy, a tiny drop of essential oil goes a long way. I buy these 10 at a time and just love them Written by Dr Gilda, 2015-02-04
Seems to work very well, Need a little more time to find out for sure Written by tom d, 2014-12-22
Everyone should try these on your CPAP/BIPAP (if you setting is above 7cmH2O). You will be suprised how much dust it removes. Outstanding product. Written by S. Bryant, 2014-12-15
these r great they last a few months n u wont wake up w glogged up sinues Written by BigC, 2014-12-13
I love this little gadget. The air smells more pure and there is less moisture. I consider this a must-have. Written by mitch, 2014-11-06
This filter installed on the outlet of my CPAP picks up anything that gets past the regular CPAP filters. After a week of use, I can see some discoloration on the filter inlet side and after three weeks the need for a new filter is obvious. Sleep is better & I don't have that stuffed up/mini cold feeling any more. Written by L Peterson, 2014-08-05
I use one filter per week. At the end of a week the filter has noticeably darkened from the material it has caught that has gotten past the machine's filter. I recommend it to all cpap users. Written by Mike, 2014-08-01
Just wanting to make clean and safe. Written by Jetmanpro, 2014-07-10
Yes, it is true that the filter will not work with humidified systems - if the filter is placed directly on the air output. Do not do that. Instead place the filter upstream between your hose and your mask. Then it will work just fine. Written by Fred E, 2014-05-26
Definitely cur down the air flow pressure, so could not use. Written by RPC, 2014-04-04
Love the filter!! Amazing how fast it got dirty. I'm getting ready to buy several more to have on hand. Written by Kathye, 2014-01-05
Delivered fast, especially during the Holiday week! It works as advertized. However, after using it for a few minutes, I realized that the moist air would not get through it so had to remove from hose. Written by Eddie, 2013-12-29
I had never tried one of these before and didn't know if air flow would be diminished or not. No problem works great. Written by Tom P, 2013-12-25
great product Written by Susan, 2013-12-22
I have the knowledge that I can have the air I breathe filtered threw this system and lessing the affects that will cause me to suffer threw the night without it and only time will tell of the difference it will make, I am happy to make that selection. Written by clear12, 2013-12-14
These are the greatest filters ever. My machine has a filter on it but I didn't know how much dust and dirt was seeping past that filter until I used this as well. This one makes me feel double secure as to what I'm inhaling. Written by Susan, 2013-10-18
Package arrived on time and in good condition. Filters are good. Service is wonderful and the price is good. What more do you want. Written by Barry, 2013-07-23
This filter fits in line from the CPAP outlet to the hose and does a good job trapping anything that might get by the intake filter or even any loose parts or dust from the CPAP machine itself. I will continue to use these filters on my wife's CPAP. The order was prompt and packaging was well done as well. Written by John, 2013-06-29
I ordered five more filters because it has curtailed my sneezing and allergic reaction. Written by Gary, 2013-04-14
Works as advertised. It does decrease the flow some but not enough to take away from the value of having it in place. Written by Blackeagle, 2013-03-18
In the past I had 3 occasions where I got a sneezing and runny nose with my CPAP. Have not had one since I installed the viral filter, which my CPAP maker does not offer Written by JY, 2013-02-28
I installed this filter in an attempt to eliminate/reduce my recurring sinus infections, even though I replaced my humidifier water daily and thoroughly cleaned all CPAP parts weekly. No infection issues for nine months since filter installation and a bonus is the filter stops humidifier mist from accumulating in my hose and mask. CPAPXCHANGE provided me with much information on what to expect with the installation of the filter since I was unnecessarily concerned. Written by SJH, 2013-02-10
Filter works Great Written by Garry M., 2013-01-20
Seems to work very well, and it's reasonably priced. Written by Bill, 2012-12-18
works great I like the fresher air compared to no filter I use consistently now Written by Dutchman 54, 2012-12-15
Don't know what to say seems catch what gets by regular filter. I would recommend using one. Written by Scott S., 2012-12-02
Filter works fine however the unintended consequence is that is causes moisture to collect in the hose and severly restricts air flow to the mask. Used it 2 nights in a row and could not continue. Written by Rich, 2012-10-18
Not sure if it helps yet Written by Linda A, 2012-08-16
They are a great value and exactly as appeared in picture on website. Written by Neal Miller, 2012-06-08
These filters attach to the hose and hose nozzle, and are very effective in reducing contaminants, no change in pressure Written by annonomous, 2012-03-23
These filters are an extra measure of protection against bacterial infection. This item does not seem to affect the function of my APAP machine. Highly recommended! Written by John, 2012-03-13
I had tried one of these as a trial purchased from a local veterinarian - they use them on their anesthesia machines. I cannot believe how gray these get after a couple months' use. I use a really good air cleaner in my home but these just add another layer of protection against all the things you can't even see. Very inexpensive, easy ta attach & a good price. Written by Cheryl, 2012-03-04
these have stopped my occasional sinus infections Even though I clean the mask, tubing and parts I started getting sinus infection that required expense trip to dr and antibiotics. This filter has eliminated those for the last 6 months. An inexpensive solution to a repeat and expensive not to mention miserable problem. Highly Recommend these! Written by obxseadoo, 2012-02-01
