Filters allergens!
These filters are great! I live in an area with a lot of cedar pollen. Since getting these filters, my allergy problems have reduced considerably. It's amazing how much nasty crud these things filter out. In a week, mine is black from all of the pollen an

Still Testing Product
No problems so far. The air coming into my mask feels and smells significantly fresher than before. Works much better than the filter on my machine. Mask, machine humidifier, and hose still need to be cleaned at least once a week, but this appears to be a

Great item
I never thought to much about using a filter like this. I thought the standard two filters on my machine would handle any airborne particles. I tried these because I kept waking up with my nose feeling plugged up. After just a few days I could see how muc

I used to have chronic sinus infections no matter how often I disinfected my mask, tubing, and humidifier. Then I tried the inline bacterial/viral filter. Immediate relief. It's been five years now without an infection and I only disinfect my mask once a

Bacterial Viral Filter for CPAP
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 chang

In-Line Bacterial Viral Filter
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 interfe

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

Seems like a good investment
I have horrible allergies and was experiencing sore throats when waking up. This doesnt 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 tim

Cpap filter
Because of this filter I can use my recalled machine while awaiting replacement or repair. I will likely continue to use this filter even after my machine is taken care of.

Excellent Product
I bought my first one to try a few weeks ago not knowing whether or not it would be helpful. To my surprise, the unit did very well in providing additional filtering of the air being inhaled. I did not notice any drastic change in the air flow and do not

Another Barrier to Germs and Viruses
I've added this to my VPAP system to add another germ/bacteria barrier to air tubing I use. I connect it to a short 1 foot tube that I use to connect to mask. Only improvement would be a twist locking mechanism instead of a slide on. But it works great as

Does a great job!
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 brow

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

good Filter
it started off doing very well but later on in the night it restricted the airflow to the point that I had to remove it. I didn't use it long enough on my machine (resmed S9) to tell if it actually stopped the bacteria .I would recommend to others but wit

Added Protection... Well Worth The Price
I never thought about the need for an inline viral filter or the benefit until the recent Ebola virus outbreak and it got me thinking that it might not be a bad idea. Well I cannot speak quantitatively to the results, however, qualitatively, the air that

After reading a positive review on the inline bacterial filter, I ordered it hoping it would help with my chronic stuffy nose when using my CPAP machine. I have to say from the day I began using this filter, I have not had a stuffy nose. It absolutely wor

A healthy add, but bulky
This device is a good idea to keep bacteria and other 'bad things' from getting to your mask, but it does create a lot of back pressure and is relatively bulky and heavy. If you can install it close to the CPAP machine outlet instead of between the hose a

I purchased a few of these as I worry about funny things making their way into my nasal cavity. Really, how clean can you get components? Have not had a problem with these and they do the job. However, you may find a lose in airflow at first. At least it

Fantastic filter...We have been using this filter for sometime now. not only does it work for bacterial viral Filter but it also catches other stuff the CPAP filter lets through. You will be happy you are not breathing what the CPAP let through..JOB well

Wonderful idea!
My filters, the gray and ultra fine white sometimes fall out unnoticed during the night because of the way the Respironics CPAP is made. With this added inline filter I don't have to worry about breathing dust particles because didn't notice that the Syst

No way to tell.
I have way to tell if this filter is traping or eliminating bacteria as I breath through my CPAP. I will say I have only used the filter for a week, and I have not noticed any difference. I realize this is not beneficial to any customers, but it is truthf

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

I haven't been using my CPAP for over a month. Then I decidedto get new equipment including the ones I've ordered from you. I can't tell you how great it feels to wake up refreshed. I feel like I can think instead of waking up in a fog with a bad headache

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

Additional filtering
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 bette
