Advanced bedding designed to protect
where it matters most
Tested in the UK's most demanding environments
SleepAngel has been independently evaluated within the UK National Health Service, including a detailed clinical assessment conducted at Barts & The London NHS Trust, one of the country’s leading teaching hospital groups.
The study, led by Dr Arthur Tucker (Queen Mary University of London), examined how standard hospital pillows and SleepAngel pillows performed in real clinical use across cardiac, vascular, and respiratory wards. The findings highlighted a risk that is often overlooked: traditional sewn bedding can become a hidden reservoir for contamination, even when it appears clean on the surface.
Investigators found that many standard pillows showed structural damage, contaminated stitching seams, and in some cases heavy microbial growth inside the pillow core within just weeks of use. Compression of these pillows was shown to create clear pathways for air — and potentially contaminants — to be expelled back into the patient’s breathing zone via stitching holes and vents.
In contrast, none of the SleepAngel pillows tested showed any internal contamination during the evaluation period. Their sealed construction and integrated PneumaPure™ filter prevented moisture, particles, and microorganisms from entering or escaping the interior, while still allowing the pillow to breathe and remain comfortable.
The report concluded that SleepAngel should be regarded as an infection-control device, offering a significant improvement over standard bedding provision and addressing risks that routine laundering and wipe-down cleaning cannot eliminate.
What the study showed:
-
Traditional sewn pillows can absorb moisture and contaminants inside the pillow core, even when the surface appears clean.
-
Wear and damage to stitching seams create pathways for air — and potentially contaminants — to be forced out when the pillow is compressed.
-
In the NHS evaluation, SleepAngel pillows showed no internal contamination during the study period, due to their sealed construction and integrated barrier filter.
Why this matters at home:
-
pillows and mattresses are compressed night after night — during sleep, feeding, and resting — directly in the breathing zone.
-
If the interior of bedding becomes contaminated, air released through seams may carry what you can’t see back toward you or your loved one.
-
SleepAngel’s design addresses this risk by filtering airflow and preventing internal build-up, helping keep the air around you or your loved ones clean and free from harmful microorganisms.
Visualising the SleepAngel difference
Not all bedding is created equal
This side-by-side demonstration shows a difference that’s normally invisible.
When traditional sewn bedding is compressed, air is forced out through thousands of tiny stitching holes — releasing whatever has built up inside the pillow directly into the sleeper’s breathing zone.
Independent testing carried out in major NHS hospitals has shown that many conventional pillows can become internally contaminated within weeks of use.SleepAngel is designed differently.
By eliminating stitching holes and directing airflow through a high-performance filter, particles are contained and cannot be released into the surrounding air. The system works both ways: air leaving the pillow is filtered, and air entering the pillow is filtered too — preventing contaminants from getting inside and stopping internal build-up over time.The result is a consistently cleaner sleep environment and added peace of mind.Because the air released from a pillow is the air you breathe while you sleep.
