Blushield C1 Cube + Ultimate Portable Bundle
The C1 and Ultimate Portable Bundle pairs Blushield's Ultimate Series stationary unit with its travel companion, giving continuous EMF protection tuned to Alpha and Beta waveforms for everyday, connected living, at home, at work, or on the move. The C1 anchors your primary space, covering up to 320m². The Ultimate Portable carries that same tuned output with you, in a lightweight aircraft-alloy case that recharges via USB-C (cord not included) for up to 7+ days per charge.
- Complete coverage for everyday, connected living: a stationary Cube for home or work, plus a portable unit for travel
- Both units tuned to the same Alpha and Beta waveforms for consistent, alert, focused energy
- C1 covers up to 320m² via tabletop placement, universal voltage for use in any country
- Ultimate Portable recharges via USB-C for up to 7+ days per charge, light enough for a pocket or bag
- Bundle pricing on two units designed to work together, rather than buying each separately

The evidence
25 people. 12 weeks. Their own homes.
Participants used Blushield in their own homes while a range of health markers were tracked. They recorded improvements across sleep, heart rate variability and cognitive performance, with no adverse events reported. The study was single-arm, with no comparison group (D'Adamo et al., 2024, n=25).
Deeper sleep
Sleep duration increased (P < 0.04), alongside measurable changes in resting heart rate and body temperature.
Improved HRV
Heart rate variability improved (P < 0.04). HRV is a measure of nervous system adaptability and recovery capacity.
Improved cognition
Cognitive performance improved across composite memory, cognitive flexibility, executive function and processing speed (P < 0.02).
Safe
No adverse events were reported, with 100% participant compliance across the 12 weeks.

Sleep has transformed for the whole household. The pyramid looks beautiful on the sideboard too — it doesn't look like tech.
Upgraded from the Cube and the difference in a larger home is noticeable. Worth the investment for whole-home cover.
Plugged it in and forgot about it — exactly what I wanted. Felt calmer within the first week.
