Mirage Activa™ LT Nasal CPAP Mask with Headgear
Prescription required
Free Returns
Mirage Activa™ LT Nasal Mask Overview
Improvements include the MicroFit dial, new compact ActiveCell technology, new diffusion vent and a dual-wall cushion that now comes in four sizes. The overall design is streamlined to be a smaller, quieter and better performing nasal mask than the original Activa.
MicroFit Dial. The MicroFit dial allows CPAP users to find the right fit using 24 small incremental adjustments. The dual-wall cushion and forehead move in tandem as the dial is turned. This design is intended to address difficultly with "first time" fittings and also helps prevent the need to over-tighten headgear.
Dual-Wall Cushions. ResMed has created the dual-wall cushions in four sizes: Small, Medium, Large, and Large Wide. This cushion is designed to fit the widest range of faces.
Improved Diffusion Vent. The Activa LT also comes with a new diffusion vent that disperses air softly and quieter than before. The exhalation ports are configured in a circular design that greatly reduces the audible sound of exhaled air and redirects the airflow away from your bed partner.
Headgear Quick Clips. The headgear comes with quick clips that allow for fast and convenient removal of the mask without the need to re-adjust.

Fitting Help
SoftGel and ActiveCell Technology are designed to seal without needing to over-tighten the mask headgear to create a secure seal. A looser fitting mask reduces pressure points and prevents red marks
ResMed also provides a printable sizing tool that has cut-outs with sizes for the Mirage Micro, SoftGel and Activa LT Sizing Template.
For more help with fitting, read through ResMed's Softgel User Guide. ResMed's Product Guide also provides helps with fitting and tips to avoid over tightening.
Where do I find the size?
The Mirage Activa LT Nasal CPAP Mask frame has two different sizes: Small and Standard. Only the small size is labeled with a letter and will accept only small size cushions. When examining the front of the mask, the size is printed on either side of the elbow, where the headgear clips attach. The Standard mask frame is not labeled and will work only with cushion sizes: Medium, Large, and Large Wide. The Mirage Activa LT™ cushion is replaceable and comes labeled. When examining the front of the mask, the size is printed on the bottom and left side of the cushion.
Convertable Use with Activa LT
The ConvertAble Series is a new 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. If you would like to purchase the DoubleGel cushion separately, please visit: DoubleGel Cushion for SoftGel Nasal CPAP Mask.
There are two frame sizes between these two 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
ResMed's Convertable Series Brochure illustrates how to change the cushions. ResMed's Patient Brochure speaks to the benefits of convertibility and other features of the SoftGel mask.
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
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.

Help Me Choose - 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.

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.
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!

- Sizing Guides. Many Nasal and Full Face masks have sizing guides available to help determine the size needed. Simply print the sizing guide, cut out if needed, and use a mirror or helper to look at the guide to see if it is a proper fit on the face. Please note, to ensure the guide is the proper size, it should be printed in PDF format at 100% scale, meaning "Fit to Page" may have to be disabled.
- Return Insurance. With every mask we sell, you have the option of purchasing return insurance. Masks are FDA approved medical devices. Once a mask is used, it cannot be resold to another customer. CPAP.com was the first in the industry to offer return insurance to our customers. Return insurance provides 30 days for you to try a mask and return it for any reason for a refund of the price of the mask. If you are trying a mask for the first time, return insurance might be right for you.
We also offer Free Return Insurance on some masks.
