no more sinus infections
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! By obxseadoo, North Carolina
In Line filter.
This filter fits on the machine and then to the hose. I have only used one but, that was enought to show me that a lot of things that were too small to see until they deposited on the filter. It showed me I was breathing in very super fine dust and dirt. It showed up on the filter. I keep my house super clean but, even then that still was not enought to keep things from being sucked up through this filter. It was stopped at that filter. I sleep longer and get better sleep than I have in a long time. I feel that it is because I am breathing better and cleaner air at night now. By Linda Strong, Schoolcraft
In-Line Bacterial Viral Filters for CPAP/BiPAP
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. By Cheryl, Chicago
A Very Worthwhile Product
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! By John, Baltimore
These filters attach to the hose and hose nozzle, and are very effective in reducing contaminants, no change in pressure By annonomous, New Haven
They are a great value and exactly as appeared in picture on website. By Neal Miller, Atlanta
No problem with this product
Not sure if it helps yet By Linda A, St. Louis
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. By Rich, Collierville
In line filter
Don't know what to say seems catch what gets by regular filter. I would recommend using one. By Scott S., Lancaster CA
in line viral filters
works great I like the fresher air compared to no filter I use consistently now By Dutchman 54, greensboro
In-Line Bacterial Filter
Seems to work very well, and it's reasonably priced. By Bill, Attleboro
Inline Bacterial Filters
Filter works Great By Garry M., Harrisonville
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.
By SJH, Minneapolis
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 By JY, PDX
cpap inline filter
Works as advertised. It does decrease the flow some but not enough to take away from the value of having it in place. By Blackeagle, Virginia Beach
Bacterial Viral Filters
I ordered five more filters because it has curtailed my sneezing and allergic reaction. By Gary, Aiea
Works like a Charm
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. By John, Texas
Very Happy Customer
Package arrived on time and in good condition. Filters are good. Service is wonderful and the price is good. What more do you want. By Barry, Sun City, AZ
In-Line Bacterial Viral Filters
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. By Susan, CA
Time will tell
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. By clear12, Homestead, Fl
great product By Susan, University Place
In line Viral Filter for CPAP
I had never tried one of these before and didn't know if air flow would be diminished or not. No problem works great. By Tom P, Gridley,IL
I guess it works fine - but no good for users with moist air
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. By Eddie, Prescott AZ
In-Line Bacterial Viral Filters
Love the filter!! Amazing how fast it got dirty. I'm getting ready to buy several more to have on hand. By Kathye, Garden Valley, CA
In line bacterial Viral Filter
Definitely cur down the air flow pressure, so could not use. By RPC, FL
A Fix for Humidified Systems
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. By Fred E, Lake Orion
In-Line Bacterial Viral Filters
Just wanting to make clean and safe. By Jetmanpro, Texas
In-line Viral Filter
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. By Mike, Carlsbad, Ca
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. By L Peterson, Clinton, Arkansas
This little gadget is awesome
I love this little gadget. The air smells more pure and there is less moisture. I consider this a must-have. By mitch, San Francisco
no more sinus infections
these r great they last a few months n u wont wake up w glogged up sinues By BigC, illinois
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. By S. Bryant, Sebring Fl.
Bacterial Viral Filter for CPAP/BiPAP
Seems to work very well, Need a little more time to find out for sure By tom d, Indiana
Filters are terrific!
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 By Dr Gilda, Londonderry, NH
CPAP BACTERIAL FILTER
Excellent product. I felt better the first day after using it. By Ken W, San Diego, CA
They seemed like a good idea....
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. By Paul D, California
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. By MarcÚlio,
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! By D. Lee, South Carolina
great product and service By claude, slc
Great Peace of Mind
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. By John, Nottringham
Sucking Air Through a Straw
Bought these to help with some allergies and it occluded the air so badly is was like sucking air through a straw. By Jo, Denver Co
Retains high amounts of moisture
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. By Larry A, Virginia
Restricts flow of air.
I decided after a few nights to remove the filter. Needed more air flow. By Skip T, 25443
It's good to use. However, its very easy to have condensation in the cold night and make breath very difficult. By Yen-Chywan L,
Not so sure
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. By kadyar, Marshall, TX
good job By J.C., Dayton, Ohio 45410
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. By David, Jackson, TN
No More Flu
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. By Matthew, Fort Worth
Extra to make sure air flow is safe. By Larry , Maricopa
Product does what is advertised to do
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. By Victor R F, Florida
Ordering my product was easy online. The discounts were applied automatically and the site was user friendly. My purchase was delivered on time. By Juan B., Daly City, CA
better than expected By h24trapman,
great product great price
works great, easy to install. After a few days you start to see the dust etc.. that it traps. Love it By mike V, Texas
Great company-great product!
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. By Barry, Sun City, AZ
Just what I ordered
I believe I am happier with my c pap since adding this filter. By Harold , DeWitt, Ia
