What to expect

A realistic timeline.

Everyone's different — here's the honest version of what most people notice, with your 90-day money-back guarantee to find out for yourself.

  1. When it arrives

    Set up in minutes

    No tools, no rewiring. Connect the filter inline, lay your mat, and start on the beginner setting.

  2. Day one

    A quieter connection

    A steadier connection right away — the buzzy feeling many people dislike should be gone, even on the gentlest setting.

  3. Week one

    Dialing it in

    Most people are grounding nightly and dialing in the strength and dosing time that feels best for them.

  4. Month one

    The calm part

    Many people report sleeping more soundly and feeling calmer in the evening. Your 90 days are there to find out.

How PEAK works

A cleaner connection to the earth, in three parts.

  1. 1

    Connect to a ground

    Your mat or sheet links to ground through a PEAK filter — via your included copper rod or a grounded outlet.

  2. 2

    The filter removes the noise

    PEAK suppresses and absorbs stray electrical noise on the line — the part many people find makes indoor grounding feel uncomfortable.

  3. 3

    Quiet, comfortable grounding

    Only a clean, steady connection to the earth remains, so each session feels calm and natural.

Questions

Answers for the healthy skeptic.

What does a PEAK filter actually do?

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.

Will it work with the mat or sheet I already own?

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.

Is it hard to set up?

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.

What if it's not for me?

You're covered by our money-back guarantee — try PEAK at home and if it isn't for you, return it for a refund. See the refund policy for details.
