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 TUBING Inline Bacterial Viral Filters are generally attached to the CPAP or BiPAP machine's air outlet; however machines that offer integrated heated tubing require the tubing to be connected directly to the machine. If you want to use an Inline Bacterial Viral Filter with a heated tube 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.
  • HEATED HUMIDIFICATION 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.
  • AUTO-ADJUSTING MACHINES 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.

    I received a damaged box with 3 filters broken. CalledDirect Home Medical and I sent pictures of damaged items. They replaced them within a few days. I started using this filter about a year ago and I am still amazed how dirty it gets even though a have 2 other filers on the cpap machine.

    I've been using this type of filter on my machine for years. I used to use the H1605 version that is clear; but these ones work just the same and are cheaper. Looks good.
