For Reference: Discontinued July 2018


Heat Moisture Exchange humidification has been used for decades in hospitals and labs; and now HME Humidifier Filters are available for users at home and when traveling as well! When using your CPAP or BiPAP the HME Filter captures heat and moisture from the air as you exhale. It then returns heat and moisture to the breathing circuit with each inhalation creating a comfortable, effective and convenient humidified breathing system.

For years CPAP users have been prone to increased allergies and sickness due to impurities in sleep therapy air. These HME Filters include a built in Bacterial Viral Filter layer, that works in conjunction with your machine's built in filters, to actively clean the air you breathe to provide exceptionally clean therapy air.

These inline HME/BV Filters are easy to install and should not require re-calibration on most CPAP machines. Simply attach the filter between your mask and your standard CPAP or BiPAP tubing. After that, turn on your machine and experience a steady flow of clean, fresh, humidified sleep therapy air.

USAGE: To install a Heat Moisture Exchanger / Bacterial Viral Filter for therapeutic use, connect the large diameter end of the HME/BV Filter to your mask and the smaller diameter end to your CPAP tube. Be sure both connections are full seated and secure. Your HME/BV Filter is now ready for use.

REPLACEMENT: Heat Moisture Exchanger / Bacterial Viral Filters are disposable and should be replaced whenever the white filter material begins to look dirty or humidification levels begin to drop -- usually about once a week with proper storage and nightly use. When not in use HME/BV Filters should be stored a sealed plastic bag (i.e. a ZipLock). The HME will immediately begin to collect moisture and humidity when exposed to air.

AUTO-ADJUSTING MACHINE NOTES: Use of Inline HME/BV 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 HME/BV Filters are not recommended.

  • Works GREAT

    I have been using for over a year, they are great. The quantity price reduction is also a plus.

  • It works!

    The ideal with my iDevilbiss Intellipap is the humidifier and distilled water for humidification.Travelling, especially to a foreign contry poses 2 problems: 1. The humidifier effectively doubles the size of the unit, space that could be used for other items in my carry-on. 2. The need for distilled water. Using the HME obviates both of these problems, However the "plumbing" needs to be modified so that the HME is close to the mask!

  • Working well for 7 days

    I've used one of these for the last 7 days and I'm happy with the result. It has been very humid where I live though, so that may affect it.

  • Filter functions as promised.

    I ordered these filters before winter for my adult son during his sailboat buying process as he was worried about how much power his cpap would draw during a weekend outing - especially on an overcast day when there was little solar power to charge the inverter/generator. They recently had a weekend boat outing and he could not find these filters but he did find that the complete cpap drained power within 5 hours. This weekend was a work on boat/sleep on boat weekend. He'd found the Universal Inline HME so this was their maiden voyage. And this is what he had to say: "They work! I had to use two rubberbands to keep the hose attached tightly to the filter...which then attached tightly to the machine. In the morning my mouth and throat did not feel dry. And I noticed no difference in the cpap performance without the actual humidifier attached. Not sure how the filters work but they do. The cpap without the humidifier uses very little power. The Goal Zero had more then 4/5th battery life after 8 hours of sleep!" I did downgrade the filters for the need of the rubberbands but they get *****+ for performance and power saving. I returned to order more of these filters from Direct Home Medical and a bag of rubberbands wherever. Thank you for a fine product.

  • No Flow

    This filter reduced my flow to about 20%. I had to remove it immediately.

  • Great for a travel cpap

    These work really well if you are using a travel cpap, I don't have to worry about buying distilled water. I really like the extra filter when staying in hotel rooms.

  • Extremeley Pleased

    This was bought for a 48 day adventure we are taking that has not started yet. Although, the In-line filter fit well and I do not see a reason they should not work well.

  • Great little gadgets when you want/need humidity

    I was very reluctant to try these out, as I am the Poster Child for wicked headaches when I run out of water in my CPAP humidifier during the night. Serious, 2 day headaches. I make it a point to not run out of water. I bought the Z1 Travel unit and since it has no humidifier, I decided to take a chance on the HME unit. Holy smokes, it works! Use it with your regular mask and the adaptor to make it fit onto your mask is included. I could quit using the humidifier on my "big" machine, but won't...the cost of these guys makes it best (for me) to travel with them only. Love, love, love the ability to not have to go find a jug of distilled water whenever/wherever I travel. From the Headache Poster Child, take it from me, the HME creates or provides (I'm not sure which) enough moisture to get through the night without a morning headache. SO great to travel with!!!

  • Couldn't handle the pressure.

    This filter in the the way that it is installed on the cpap with the hepa filter on top of the blue sponge and the direction of air coming up from under the blue heading toward the white filter then int the mask, causes the white filter to come part from the blue when cpap machine is set at high level (I.e. Mine is set at 14) making the filter un-useable.

  • Super Travel Alternative to Dragging a Water Heater Tank Around

    I have a "portable" APAP that is approaching the size of a brief case. I travel a fair amount and purchased a more compact Trancend device to use on trips. I skipped the water heater attachment to use this in-line solution. It has been working great for me. Try it, you'll like it.

  • Costs less, works the same

    These lower priced HMEs became available since my last purchase of HMEs, so I thought I'd try them. They work exactly the same as the other ones and will save me money. I'll be using them from now on.

  • Humidification

    I saw these advertised and thought I'd try them. I have been using the inline bacterial filters ever since I had a nasty respiratory infection last year I just couldn't kick. I have not had an infection since, not even a cold. My APAP machine is very noisy especially with the humidifier. I tried this filter with the humidifier disconnected and it worked fine with a little less noise. I also bought these to use with my portable Transcend which doesn't have a humidifier

  • Portable Humidifier

    This great little device works great in a camping situation. It did keep me from being dried out in the morning on a camping trip where I was running my CPAP off of a battery, so I could not use my usual humidifier.
