About HavenFog 1-Quart
HavenFog is an intensive, whole-room mold treatment designed to reach the nooks and crannies that surface sprays miss — ceiling corners, wall cavities, HVAC ducts, and furniture undersides. One quart of HavenFog solution treats up to 1,000 square feet when used in a hot fogger, dispersing a fine citrus-extract mist that neutralises airborne and surface mold without harsh chemicals or residues.
HavenFog is non-toxic, safe around pets, plants, and children, and is formulated specifically for households with chemically sensitive occupants. It is a safe and effective mold treatment choice for people with chemical sensitivities — backed by an MSDS of all zeros for harmful chemicals.
Key Ingredients
HavenFog is built on a citrus seed extract base developed by CitriSafe, BioBalance's sister company and the manufacturer of the Haven™ formula. The active compounds include:
- Grapefruit seed extract — broad-spectrum antimicrobial; disrupts mold cell membranes on contact
- Tangerine seed extract — enhances surface penetration and dispersal
- Lemon seed extract — citrus-derived antifungal and antimicrobial support
- Lime seed extract — reinforces citrus terpene activity across a wide range of mold species
The naturally occurring terpenes within these citrus seed extracts are classified as Generally Recognized as Safe (GRAS) by the FDA. These ingredients leave no toxic residue, require no PPE, and produce no harmful off-gassing.
What's Included
- HavenFog™ 1-quart (32 oz.) Intensive Mold Treatment solution
Note: A hot fogger is required to use this product. If you need a complete kit with a fogger and mold test plates included, see the HavenFog Mini Kit.
Material Safety
HavenFog has a Material Safety Data Sheet (MSDS) of all zeros for harmful chemicals — meaning no reportable hazardous substances, no toxic residues, and no dangerous off-gassing. It is one of the few mold treatment products on the market with this distinction, and it is the standard we hold every Haven™ product to.
People and pets should not remain in the treatment area for extended periods during fogging. It is best to leave the fog undisturbed for 24 hours after fogging is finished. Re-entry after 12 hours is acceptable. Ventilate the treated areas when people or pets return.

Frequently Asked Questions
What is HavenFog 1-Quart and how does it differ from the HavenFog Mini Kit?
HavenFog 1-Quart is the fogging solution only — it does not include a fogger. It is ideal for customers who already own a compatible hot fogger and want to purchase refill solution. The HavenFog Mini Kit includes the solution, a hot fogger, and mold test plates in one package.
What are the active ingredients in HavenFog?
HavenFog contains grapefruit seed extract, tangerine seed extract, lemon seed extract, and lime seed extract — all citrus-derived compounds. These citrus seed extracts are all classified as GRAS (Generally Recognized as Safe) by the FDA. The formula is non-toxic, fragrance-free, and leaves no harmful residue.
When can people and pets return after fogging?
People and pets should not remain in the treatment area for extended periods during fogging. It is best to leave the fog undisturbed for 24 hours after fogging is finished. Re-entry after 12 hours is acceptable. Ventilate the treated areas when people or pets return. Begin small particle cleanup 24 hours after fogging is finished, even if people or pets return after 12 hours. Cleanup time depends on the area to be cleaned and the thoroughness of the process.
How much area does one quart of HavenFog treat?
One quart (32 oz.) of HavenFog treats up to 1,000 square feet per treatment cycle. For larger spaces, see the HavenFog 1-Gallon (4,000 sq. ft.) or the HavenFog Kit which includes the 1-Gallon solution and fogger.
Do I need a special fogger for HavenFog?
HavenFog requires a hot (thermal) fogger — not an ultrasonic or cold fogger. A hot fogger atomises the solution into a fine, penetrating mist that reaches hidden areas. The HavenFog Mini Kit and HavenFog Kit both include a compatible hot fogger.
How often should I fog my home for mold treatment?
HavenFog is intended as a one-time treatment. Additional treatment may be needed if a significant mold problem has not yet been remediated or after another water event. Use HavenMist for continued maintenance.
Is HavenFog safe for people with chemical sensitivities?
Yes. HavenFog was formulated with chemically sensitive households in mind. The citrus seed extract formula carries an MSDS of all zeros for harmful chemicals, produces no toxic vapors, and leaves no chemical residue. As with any product, individuals with known citrus allergies should consult their physician before use. For mold-related health concerns, we recommend working with an integrative physician or contacting Fight Mold Exposure for guidance.
