RDS develops products that are small, convenient to use, effective and inexpensive.


Microchamber® is an aerosol holding chamber for use with metered-dose inhaler products.

The Microchamber® unit can be attached to a metered-dose inhaler in seconds, and can be easily detached for cleaning and drying. Microchamber® provides a chamber device that is small, convenient, effective, and less expensive than other chamber devices.

Microchamber® performs just as effectively as the larger chamber devices, but retails for 50% less!


Microspacer® is an aerosol spacer device for use with metered-dose inhaler products. It represents a technological breakthrough regarding proper airway disposition of asthma medication. Microspacer® reduces “impactor throat” deposition over 70%, but that is only one factor in the Microspacer® story!

The vestpocket-size Microspacer® extends the mouthpiece of a metered-dose inhaler only one inch, and weighs less than one ounce. The Microspacer® can be attached to a metered-dose inhaler in seconds, and can be easily detached for cleaning and drying. Each Microspacer® is constructed of durable, recyclable plastic, and should last from four to six months before requiring replacement. Microspacer® outperforms the larger spacer devices regarding percentage of respirable dose delivered.

Breathe better. Live healthier. With better results.

I have been very pleased with your product, the Microspacer. It’s small size, low cost and ability to easily clean it have made it a very useful spacer for my patients to employ when delivering inhaled medication.

Atlanta, GA

I must commend you on the Microchamber size compared to the larger volume chamber devices. Due to your products size, it makes it very easy to carry and also convenient to assemble and use. Thank you very much for your time and efforts. You have greatly assisted in improving my quality of life.

Windsor, WI

All my C.O.P.D. patients love using your Microchamber with their inhaler products. They find the product delivers the aerosol medication more effectively.

Portland, OR

I am an asthmatic and I just want to tell you how much I like your Microspacer product. My inhaler product is useless without some sort of spacing device and those bulky chamber devices take up more space in my purse than my cell phone. The Microspacer should be included with every inhaler, so more people can benefit from their portability. I thank my doctor every time I see him for introducing me to your Microspacer.

Westlake Village, CA

Thank you for your Microspacer, without which I would be in great trouble! I can’t use inhalers effectively without it. I have exercise-induced asthma triggered by cold air or pollen. With the Microspacer I know I’m getting the medicine immediately. Thanks again for a product that gives me a lot of peace of mind.

Cambridge, MA

I am an avid user of your product, Microspacer. I have asthma and COPD. I use inhalers frequently and I have found that your product delivers the medication better than anything else.

Bosque Farms, NM

The Microspacer is a wonderful tool. It is so easy for me to carry around in my purse for emergencies. I know my sons are always getting the proper dose with the Microspacer. Even more important, my sons can easily carry them in their backpacks, soccer bags and even jacket pockets. Again, thank you so much.

Potomac, MD

I am an elderly woman that has asthma and C.O.P.D. The Microchamber makes it easier for me to take my inhaler medications and conveniently fits into my purse. Thank you!
