Silver-Free EDTA Nasal Spray: EDTA and Xylitol, Without the Silver
BioFilm Clear-X
EDTA and Xylitol, Without the Silver
A silver-free EDTA nasal spray is what many people end up searching for after reading about EDTA's biofilm research but deciding — for their own reasons — that colloidal silver isn't for them. BioFilm Clear-X is exactly that product: the same EDTA-and-xylitol foundation as our flagship spray, formulated without silver.

The Choice
Why some people prefer silver-free
Colloidal silver is the most-discussed — and most-debated — ingredient in this category. Some users specifically want it; others prefer to avoid it, whether out of personal caution, practitioner guidance, or simply wanting the fewest ingredients possible. We make both versions so that choice stays with you:
| Ingredient | BioFilm Clear | BioFilm Clear-X |
|---|---|---|
| EDTA | ✓ | ✓ |
| Xylitol | ✓ | ✓ |
| Grapefruit seed extract | ✓ | ✓ |
| Colloidal silver (30 PPM) | ✓ | — |
| Iodine complex | — | ✓ |
| Saline / salt | none | none |
Both are salt-free (no saline), preservative-free, and made in the USA in a cGMP-certified facility.
The Foundation
What EDTA and xylitol are doing in the bottle
EDTA
A chelating agent — it binds metal ions. Independent researchers have studied it for its effect on the structure of biofilms, the protective matrices bacteria build around themselves, including in the nasal passages. A 2026 review in Frontiers in Antibiotics examined EDTA as a broad-spectrum antibiofilm agent working through exactly this mechanism.
Xylitol
A plant-derived sugar alcohol studied for its role in nasal cleansing. It also gives the spray a mild character suited to twice-daily use.
Choosing between Clear and Clear-X
There's no “better” version — the flagship is for people who want silver in the formula; Clear-X is for people who don't. Households commonly keep both. If you're working with a practitioner, show them the ingredient lists and let that guide the choice.

Compare both formulas →Common Questions
Silver-free, answered
Is Clear-X weaker than the flagship?
It's not a strength question — it's an ingredient-preference question. Clear-X keeps the EDTA-xylitol foundation and swaps colloidal silver for an iodine complex.
Why is your silver spray salt-free?
Salt destabilizes colloidal silver — it's why the whole product line is formulated without saline. Clear-X inherits the same salt-free base.
How often can it be used?
It's designed for routine daily nasal hygiene — most users spray once or twice daily.
