Integrated Technology Helps Active Sleepers Get Better Sleep
Thanks to ActiveCell Technology, restless sleepers have the freedom of movement during sleep without compromising their mask seal as frequently. The bubble–style membrane surrounding the dual–wall cushion expands and contracts to accommodate changing pressures and permit various sleeping positions throughout the night.
New and Improved Air Vent and Headgear Clips Reduce Noise and Offer Convenience
With a new diffusion vent designed to disperse air more softly and quietly than ever before, the Activa LT has exhalation ports configured in a circular design that reduce the audible sound of exhaled air and redirect the airflow away from you and your partner.
What’s Included:
- Mask
- Cushion (in preferred size)
- Headgear Clips
The ConvertAble Series is a ResMed concept that allows cushions to interchange with other masks. The SoftGel frame and Activa LT frames are identical in size. The ActivaCell or DoubleGel cushion will work with either mask.
There are two frame sizes between the SoftGel and Activa LT masks. The size small is the only system that cannot change mask sizes. We recommend the following conversion equivalent chart:
- Small Activa LT and Small SoftGel masks only accept Small size cushions
- Size Medium/Large/Large Wide Masks will fit either DoubleCell or ActiveCell cushion in any size other than Small
The Mirage SoftGel is built around the Activa LT frame, If you would like to purchase the DoubleGel cushion separately, please visit: DoubleGel Cushion for SoftGel Nasal CPAP Mask.
Activa to Activa LT
If you are currently using the Original Activa Mask or Ultra Mirage II Nasal and want to purchase the Activa LT, we recommend the following conversion equivalent:
- Standard Activa size Standard = Activa LT size Medium
- Standard Activa size Shallow = Activa LT size Large-Wide
- Standard Activa size Large = Activa LT size Large
Activa LT Sizing
For help with selecting the proper size cushion, use ResMed's Activa LT Sizing Guide.
Inlet Air Tube
The Mirage Activa LT no longer uses the 10 inch Inlet air tube that extends your hose away from the mask. The Inlet tube for the Original Activa Nasal CPAP Mask can be found here: Inlet Tube with Swivel Assembly
Headgear
This package DOES NOT include Headgear. Headgear can be purchased separately or along with the fitpack Headgear for the Mirage Activa™ LT; Mirage Activa LT Nasal CPAP Mask with Headgear.
Headgear for the Mirage Activa LT comes packaged with the ResMed Medium/Standard Size 16117. If you are referencing ResMed's Component Card from their website you will be ordering a headgear and clips different from the style that came with your Activa LT. ResMed Headgear 60114 Standard will work with the Activa LT, but the mask clips, part number 60115, that come with this headgear are incorrect. Please order these ResMed Headgear Clips (16569) to work with your Activa LT.
General Product Advisory
- Activa LT cushions and clips are compatible with the Original Activa Frame, but are not EXACT replacements
- The Activa LT frame is slightly smaller than the Original Activa mask frame; do not mix and match cushion clips
- Activa LT cushions work in conjunction with other Activa LT improvements; We recommend using the entire Activa LT mask
Any mask will work with any machine, with one important exception. The ResMed AirMini is only compatible with certain ResMed CPAP masks. Compatible masks for the AirMini are as follows:
- ResMed AirFit™ N20 Nasal Mask
- ResMed AirFit™ F20 Full Face
- ResMed AirTouch™ F20 Full Face
- ResMed AirFit™ P10 Nasal Pillow
When considering another CPAP, APAP or BiPAP machine from ResMed or any other manufacturer, mask compatibility extends to all brands. The AirMini uses non-standard tubing to connect the machine to the mask, and is the primary reason why other masks won't work with the AirMini. Despite this issue, many of our customers consider the AirMini to be an excellent machine.

Masks should be washed daily with warm water and gentle soap or baby shampoo. Let the mask air dry. Never use antibacterial soap as it will break down the silicone of the mask cushion. Avoid soaps that include lotion which can coat the mask and cause it to lose its seal. A safe cleaner is the Control III Disinfectant CPAP Cleaning Solution. Remember, going to bed with a clean face will improve your seal and protect the lifespan of your mask. 
The best time to clean your mask is in the morning after use. This removes the oils left behind from your skin which can reduce the lifespan of your mask. We recommend using Mask Wipes to make daily morning cleaning easy. The mask wipes are made from materials that will not break down your mask.
For customers who want to completely disinfect their mask and accessories, there's an even better option than wipes. The Lumin Mask and Accessories Cleaner uses powerful UV light to disinfect, killing almost all bacteria almost instantly. It's not a cleaner and doesn't scrub or wash anything, but for simple disinfecting the Lumin works great!
Here are some other cleaning products to help with keeping your mask fresh:
Citrus II CPAP Mask Spray Cleaner
Control III Disinfectant CPAP Cleaning Solution - Home Care Kit
In our experience, most mask cushions begin to deteriorate after about six months of use. The cushion eventually becomes too soft to hold a seal. The headgear straps lose elasticity and must be tightened more and more to get the same quality seal.
We strongly suggest replacing cushions and pillows as soon as they start to soften. Air leaks may reduce the effectiveness of CPAP therapy and headgear that is too tight may cause facial sores at pressure points. In most cases, replacement headgear is available if it is stretched out or the Velcro worn out.
To see what parts of your mask are replaceable refer to our Replacement Part Finder. Just search for your mask to see all of the replaceable parts.

The ordering and shipment was convenient and easy. Shipment took longer than expected, but wasn’t too bad. Product is... WONDERFUL! This nasal assembly kit fit perfectly and is very comfortable. One of the best comfort and less stress on the areas around my nose. Love ?? it! more...
This is an excellent product the folks were so helpful when I called. Delivery was faster than expected!
Looks like they tweeked the upper part of the mask so it doesn't have to be adjusted constantly. Works... for me. I've used this particular mask for many years. That's why I keep ordering it. more...
I like this mask better than any other one I have tried. My sleep doctor's office no longer carries... it but, I found it still here on CPAP.com more...
cpap.com price, delivery & service is fantastic. ResMed Customer Service leaves alot to be desired. I was a... longtime multi-yr user of ResMed masks and machines. When they decided to stop production of this mask, I tried to contact them to determine which of their newer designs might work for me. Trying to find a phone number, a web-link, or an e-mail address for ResMed Customer Service Department is virtually impossible. When I finally was successful in reaching someone, I was told, "We really didn't have a recommendation of which new models you should try. We don't have time to give out recommendations to everyone who calls in." Guess if they don't care about helping a longtime loyal customer, I'll go to their competitors for my supplies and machines in the future. Now I discover: ResMed's business model appears to be built around shady business practices. They keep making numerous products obsolete to increase consumer replacement prices, and they just had to pay a 35.7 million dollar Federal fine for illegal kick-backs to doctors & fitters. As ResMed loses their business, May their Company Rest In Peace. Heaven only knows if their loyal customers will. more...
The information on order was not correct. Things were ordered that I didn't put on my order. There is still... a number in my art that I did not put there. more...
I have used this model of mask for years, I always get excellent service and fast shipment when I renew... my needed items. more...
I have used this mask for years and highly recommended this product. It is light and very comfortable... to wear. more...
I bought this mask a couple of days ago and the night I used it I was impressed with how... it did not have any air leaks. When I first started with my CPAP machine i would always lay on my back. Now I sometimes end up laying on my sides and that is where the old mask would start to leak and wake up my wife. With this mask if I turn to the side or if I put my chin down to my neck it does not leak, and I have the full therapy the machine is at its peak. Still no leaks. I am sure as the mask gets more use it will breakdown but so far this is the one for me. more...
High quality products
It only took about 3 days to get my product and then I love that it can be put on... a notification system when it's time to replace. Always have great service from this company and prices are reasonable as well more...
I recently switched to this mask after using the Mirage Active for years. It has a smaller cushion and no... forehead support (which never touched my forehead while wearing). It's comfortable and feels less confining. more...
