Benefits & FAQ

Indoor grounding connects you to your home's wiring, bringing you the benefits of grounding, but also any stray electrical noise riding on it. The PEAK filter sits inline and removes up to 95% of that noise, so only a clean, steady connection to the earth reaches your mat. Read the science.

Many people report sleeping more soundly, feeling calmer in the evening, and feeling less achy and more rested. Everyone's different — grounding research is young, and we frame benefits as what research has explored and what users report, never a guaranteed outcome. Browse the research library.

Often it's the electrical noise (“dirty electricity”) on your home's ground line, not the grounding itself. Filtering that noise is exactly why PEAK exists — and the Pro's 12-hour dosing timer lets you ease in gradually to get acclimated.

Yes. PEAK filters use standard snap connectors, so they work with virtually all grounding mats, sheets, and pillowcases — including ones you bought elsewhere. Still want to be sure it works with your setup? Contact us! We'll be happy to help.

No tools, no rewiring. Snap the filter inline to your equipment or get setup with our bundle and you'll be grounding better in minutes. See the step-by-step setup guide.

Same filter expertise in every tier, but a few key differences: Basic is always-on. Pro adds the 12-hour dosing timer for controlled sessions. Extreme is our strongest and most robust filter — dual-stage low + high frequency filtering plus the timer and the beginner-to-advanced strength dial. Take the 60-second quiz to find your fit.

Yes, however each PEAK filter is engineered for ideally one person, so the filtering strength and Schumann frequencies may be degraded if extending or splitting the output. Grounding as a pair? Add a bundle for each person — 5% off any 2+ bundles (10% off 3+) is applied automatically at checkout.

Both work. The outlet uses your home's existing ground wiring; the included copper rod gives you a dedicated, direct earth connection which is usually a cleaner ground. Also handy for ungrounded outlets, apartments, or anyone who prefers a separate path.

No. They're fully passive — nothing to charge, nothing to plug into a powered socket. The filter simply sits inline between your ground connection and your mat.
