About HavenFog 1-Gallon
HavenFog is an intensive whole-room mold treatment — a non-toxic, natural, citrus-based solution for safely treating mold in every nook, cranny, ceiling space, and air duct of your home or office. Formulated specifically for use in hot foggers, the 1-gallon size treats up to 4,000 square feet and is the most economical option for larger homes, whole-house treatment programs, or repeat seasonal treatments.
Because HavenFog is non-toxic, there is no need to remove people, pets, or household items during treatment. In fact, it is best if all household items go through the fogging process — the microscopic citrus droplets reach surfaces and airspaces that manual cleaning and surface sprays miss entirely.
Key Ingredients
HavenFog is formulated with a blend of citrus seed extracts recognized as safe and effective for environmental mold management:
- Grapefruit seed extract — naturally derived antimicrobial concentrate
- Tangerine seed extract — broad-spectrum citrus antimicrobial
- Lemon seed extract — a naturally occurring GRAS-listed citrus compound
- Lime seed extract — complements the citrus terpene complex
These extracts are GRAS-listed (Generally Recognized As Safe) and sourced through CitriSafe, the manufacturer of the Haven™ base formula.
Material Safety
HavenFog has a Material Safety Data Sheet (MSDS) of all zeros — meaning zero harmful chemical ratings across all hazard categories. This makes it the responsible choice for mold treatment in homes with children, pets, plants, and chemically sensitive individuals.
Formulated by a Registered Pharmacist
"The Haven™ product line was formulated to give families and practitioners a safe, effective, non-toxic option for managing environmental mold without the health risks associated with conventional chemical treatments."
— Walter Hayhurst, RPh, Registered Pharmacist and founder of Professional Compounding Centers of America (PCCA), the world's largest network of independent compounding pharmacies
What's Included
- HavenFog™ 1-Gallon Intensive Mold Treatment Solution (treats up to 4,000 sq. ft.)
- For use in any standard hot thermal fogger (fogger sold separately)
Safe and Easy to Use
No need to remove furniture, clothing, or household items. Leave pets and plants in the home. The fog permeates porous materials, ceiling spaces, HVAC registers, and areas that cannot be reached by spray or wipe treatments. After fogging, simply ventilate by opening windows for 15–30 minutes.

Frequently Asked Questions
What is HavenFog made of?
HavenFog is formulated with grapefruit, tangerine, lemon, and lime seed extracts — a citrus terpene complex developed by Walter Hayhurst, RPh. All ingredients are GRAS-listed and non-toxic. The MSDS shows zero harmful chemical ratings across all hazard categories.
How much area does the 1-gallon treat?
One gallon of HavenFog treats up to 4,000 square feet. It is the most economical option for large homes, multi-room treatment programs, or ongoing maintenance fogging. The 1-quart (Mini Kit) treats up to 1,000 sq. ft. for smaller spaces.
Is HavenFog safe to breathe during fogging?
Yes. HavenFog has an MSDS of all zeros, meaning no harmful chemical ratings. The citrus-based formula produces no toxic vapors. Many users remain in the space during fogging without adverse reactions. However, ventilating after treatment by opening windows for 15–30 minutes is recommended standard practice.
Do I need to remove pets and children before fogging?
No removal is necessary. Because HavenFog is non-toxic, pets, plants, and people can remain in the home during treatment. The fog is safe for all household members, including those who are chemically sensitive.
What fogger is compatible with HavenFog?
HavenFog is designed for use in hot thermal foggers, including the HavenFogger available from BioBalance. Standard hot foggers in the 400–1500 watt range are generally compatible. Cold foggers (ULV foggers) are not recommended as they do not produce the fine particle size needed for optimal penetration.
What is the difference between HavenFog 1 gal. and the HavenFog Mini Kit?
The HavenFog Mini Kit includes a 1-quart solution and a fogger, making it a complete starter kit for spaces up to 1,000 sq. ft. The 1-gallon solution is the refill/bulk option — it is solution only (no fogger included) and treats up to 4,000 sq. ft. It is ideal for existing HavenFog users who need a larger volume or lower cost-per-treatment for ongoing maintenance.
How often should I use HavenFog?
Treatment frequency depends on the severity of your mold situation. For significant or widespread mold, an initial intensive treatment followed by quarterly maintenance fogging is common. ImmunoLytics mold test kits can be used before and after treatment to measure spore count reduction and determine whether re-treatment is needed.

This product is awesome. It really worked to reduce my symptoms and my tinnitus improved too. Also, I like that the fog caused no adverse reactions during the fogging process. I was surrounded by dense fog but experienced no issues…I actually enjoyed it! My pets did not seem to mind either- I was expecting them to be scared. I would definitely recommend this product.

I have been using bio balance products for close to 20 years and they have been so effective to treat our homes and create a healthy environment for my entire family. I highly recommend these products and the customer service is excellent.

Wonderful product. Obviously not cheap, but if you can swing it, it does save a lot of money compared to buying the smaller size. Saves even more money compared to someone coming to your house to fog it for you. I’ve paid people more than this to fog my house one time, whereas this 1 gallon bottle lasts me many uses. Treats my basement exactly how I need it to, and it’s easy to use with a fogger. It literally transforms my basement from musty to perfectly clean every time. I have a lot of health issues and keeping the mold and bacteria down in my home with this product has helped me more than I can explain!

Extra fog is great to have with our Bio Balance Haven Fog machine. We fogged our whole house once and are able to keep living in it. If in another year or so more mold appears we can fog again! Don’t believe the nay-sayers online. Fogging mold really works!
