With viral and bacterial filtration efficiencies of over 99.99% the Hudson 1605 Universal Inline CPAP Filter comes complete with holders as shown. Hudson's filter technology helps stop the viruses and bacteria that often plague sleep therapy users creating a clean, sterile environment for a healthy night's sleep.

Inline Bacterial Viral Filters are a great option for sleep therapy users who are prone to sickness or allergies. They actively clean the air as it leaves your CPAP or BiPAP machine, working in conjunction with the machine's built in filters, to provide exceptionally clean air throughout the night.

These Universal Inline Bacterial Viral Filters are naturally hydrophobic so they allow maximum filtration with a minimum loss of air flow. Each unit is sonically sealed so there are no chemical adhesives or unwanted material residue. Universal Inline BV Filters are easy to install and should not require re-calibration on most CPAP machines. Simply attach the filter to your machine between the air outlet and your standard CPAP tubing. After that, turn on your machine and experience a steady flow of clean, pure, good tasting air.

USAGE: Inline Bacterial Viral filters are disposable and should be replaced whenever the white filter material begins to look dirty. These filters will last on average 4-6 weeks before needing to be replaced, however your filters may last for a longer or shorter amount of time depending on environmental conditions.

HEATED HUMIDIFICATION NOTES: Some users find that using in-line Bacterial Viral filters can reduce pressure and therapy effectiveness in humidified CPAP machines. If you experience reduced pressure when using an Inline Bacterial Viral Filter with a humidifier, remove the filter and allow it to dry out completely before re-installing on your system or discontinue use of the Inline Bacterial Viral filter completely.

HEATED TUBING NOTES: Inline Bacterial Viral Filters are generally attached to the CPAP or BiPAP machine's air outlet; however machines that offer integrated heated tubing (i.e. PR SystemOne 60 Series Machines, S9 Machines, AirSense 10 Machines, ICON Machines, etc.) require the tubing to be connected directly to the machine. If you want to use an Inline Bacterial Viral Filter with one of the machines listed above consider attaching the BV Filter at the end of the heated tubing closest to the mask. If that is too bulky for you a FeatherWeight connector tube can be added to move the BV Filter further away from the mask attachment.

AUTO-ADJUSTING MACHINE NOTES: Use of Inline Bacterial Viral Filters may adversely effect auto sensing on Auto-CPAP systems especially at pressures below 7 CM H2O. If your average treatment pressure is below 7 CM H2O Inline Bacterial Viral Filters are not recommended.

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 Done

Wonderful idea!
Written By: CB, MA 10/12/2016
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 System One filters came out. Whoever thought of this: GREAT idea and many THANKS!

Great item
Written By: Russ, Southern California 9/23/2016
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 much these filters were helping. The white filter was turning brown from all the dust it was picking up and I was sleeping better. I will never go without using these filters! I've stocked up on them. I change the filter when they start to look to dirty, about once a month unless I'm traveling, then a little more often. I buy them when they are on sale, so it costs less than $2 a month to breathe fresh air.
