Product Description
Don't let the lack of reviews dissuade you. Many of my customers are people who come into our shop rather than ordering online. I have had - I would say - a good 95% positive feedback from people who have had stubborn sinus issues, whether polyps, sinus issues that don't seem to clear after an infection having been treated, etc. You will see at the end Phil's recommendation for using NanoSpray in conjunction with Flonase and Sudafed for sinus infection.
True Story...This Product Is Personal.
For years, Fall and Winter meant one thing for Phil (one of the co-founders of Silver Fern™ Brand): sinus infections — again and again. Every cold turned into something worse and he would constantly be at the doctor’s office getting another round of antibiotics. Rinse, repeat.
Phil tried everything! He tried sprays, rinses, OTC meds, zinc, elderberry and more, but nothing worked. Eventually, even antibiotics stopped helping and he was stuck in a cycle of stronger prescriptions and weaker immunity. Small colds often became big problems.
On top of all of those issues, Phil has always had allergies and year-round congestion. And living in Utah, one of the driest states in the country, made things even worse. So with that background in mind, we decided to get him some help and came up with a couple options. *
Nano Spray and Nano Spray Pro are the Silver Fern™ Brand answer to helping the microbiome of the sinuses.*
Nano Spray
We started with a real need: clear out the buildup in the sinuses and support a healthier nasal microbiome.*
Nano Spray uses frequency-activated nano Ag4O4 (purified silver), not traditional colloidal silver. This form of silver offers multiple strike actions that help disrupt unwanted microbes, even in small amounts.*
What makes Nano Spray different?
- Exits the body within 24 to 72 hours*
- Supports ongoing microbial balance with continual strike actions*
- Manufactured in an FDA-audited facility*
- Silver is GRAS certified*
Other silver products typically are not effective unless used in very high doses and can build up in your body. They also don’t come backed by quality manufacturing and well documented safety studies. Don’t take your chances with anything else, get Silver Fern™ Brand’s Nano Spray today for unmatched sinus microbiome support!*
Nano Spray Pro
Nano Spray Pro takes everything in Nano Spray and levels it up. By adding RiaGev®, xylitol, menthol, and sodium chloride, Nano Spray Pro offers next-level support for those with serious issues.
Here’s what Nano Spray Pro may help with:
- Hydrates dry nasal passages*
- Soothes irritated nasal tissue*
- Supports healthy nasal microbiomes*
- Encourages balanced immune responses in the upper respiratory tract*
- Helps rinse away allergens, airborne irritants, and excess mucus*
- Promotes healthy airflow and easier breathing*
- Provides a refreshing, cooling sensation*
When and How Do You Use Our Nano Sprays?
- Shake well before each use
- Spray 2 times per nostril (4 total) up to 3 times per day
- Slight orange color is normal from ingredients
- Use daily or as needed—especially helpful during travel, dry seasons, or when you're feeling run down*
Formulated for regular, everyday use.


When and How Do You Use Nano Spray?
You can use 2 sprays up to 3 times daily. Children can use 1 spray up to 2 times daily.
For getting rid of a sinus infection, Phil recommends:
"The answer may surprise you because it isn’t all about our products. This is a magical combination that
if you use it for a week or two should help the sinus infection not be an issue anymore.
1) Sudafed. Using a strong dose of Sudafed. Sudafed helps reduce swelling and inflammation that
causes sinus congestion. I use the strong kind of Sudafed (behind the Pharmacist desk that you
have to ask for) twice a day (the 4 to 6-hour type or 1 12-hour capsule) and then at night I use
Benedryl, which also helps provide relief from sinus pressure and nasal congestion.
2) Flonase. Using Flonase will help reduce swelling in the nasal passage. To help with a sinus
infection you need to help clear the nasal passage. I use 2 sprays per nostril morning and night
(4 sprays per day per nostril).
3) Nano Spray. Using Nano Spray helps manage the microbiome of the nasal pathway. I suggest
using Nano Spray at different times of the day than when you take Flonase. The combination of
Nano Spray and Flonase works great. *"
