How to Use Your CaptureCards

The TrueClean team

Hi — we're the TrueClean team.

Set Up Your Cards

1

Open the box

CaptureCard box — old and new version

Old box or new box — the same cards inside: 4 sealed pouches, one card in each.

2

Tear one pouch at the notch

Take out the green card.

3

Do not cut the card

The green CaptureCard

The card works closed. If you open it, it stops catching. You open it once — at month 3, to look inside.

4

Place your 4 cards like this

Keep cards 10–20 inches from your head: close enough to lure mites away from you, far enough to stay off your nose. Cover as much of the bed as you can.

Sliding a card under the fitted sheet

Slide each card flat — you will not feel it. More cards? Use 2 per pillow and spread the rest over the bed. Sofas: 1–2. Pet beds: 1.

5

Done. Set a 90-day reminder

Replace each card within 3 months.

  • ✎︎Today, write down how you wake up — nose, sneezes, skin. You will compare at day 90.
  • ↔︎Move each card monthly, so it traps more. A hand's width is enough.

How to See the Dust Mites

Optional. Do this at month 3 — not before. An early cut shows nothing and stops the card.

First, three things to understand:

  • 1A dust mite is 0.3 mm and almost transparent. You cannot see one by eye.
  • 2We added mite food with a dye inside. Mites that feed enough on it become visible — as dark specks.
  • 3Not all mites feed enough to show. Specks need a lot of mites — not every home has that many.
The insert pad with dark specks

What you are looking for: dyed mites on the white pad.

You may see specks. You may see none. Both are normal.

If you see none, the usual reasons:
  • No backlight. The light must shine up through the pad.
  • The room is not dark enough.
  • Zoom under 10x. Use the newest phone in the house.
  • The card was cut before 3 full months.
  • That spot had few mites. Give the next card a new spot.
  • Or your home has few mites. Good news — the card still catches the ones near you.
1

Cut the card open

Cutting the card open

Cut one edge with scissors and pull out the insert — a yellow mesh sheet with a white pad.

2

Light it from below

Insert glowing on a glass over a phone flashlight

Turn on your phone's flashlight and lay the phone on a table, light facing up. Stand a clear glass on the phone. Lay the insert flat on the rim — the light shines up through the glass and the pad.

3

Zoom in from above

Phone at 10x zoom showing pepper-like specks

Make the room dark. Take a second phone — anyone's in the house. Hold it above the pad and zoom to 10x. Move slowly — the specks look like pepper. Only one phone? Rest the insert on a bright laptop or tablet screen and zoom with yours.

Then bin it all and wash your hands.
