How to Properly Clean These “HEPA Filters” and Improve Your Indoor Air Quickly

By Cesar Collado

I often get asked what are the most important things patients can do to feel better sooner.  Surprisingly, this question is easy to respond to and it is simple to execute.

First, as an example, when you have a wound, you keep it clean and covered to prevent infection and to help it heal.  When it comes to mold, our sinuses need protection from continuous exposure to mold spores in our air and also need care to heal from infection too. Today, I will present the two helpful ways to clear your sinuses and your home of mold spores. More specifically, in my opinion, these offer the “Best Bang for the Buck” when it comes to feeling better.

Clearing the Sinuses of Mold

Since mold spores are constantly assaulting the body through inhalation, the body does not have a chance to fully clear all mold-infected mucous and employ its metabolism process to eliminate the antigen. Ironically, because our immune system recognizes the mold as an invader, it then kicks in as our natural first responder and causes infection with mucous production, which then aids the mold in reproducing at alarming rates inside our sinuses.

Consider a HEPA filter in your home or air conditioner:  Air passes through the filter, which traps the mold and mycotoxin particles so that conditioned (“or clean”) air is circulated in your home.  In the end, the contaminated filter must be removed and carefully discarded immediately, since it is filled with contaminants.

Our sinuses, and to a lesser degree, our lungs, serve that same filtering purpose.  We breathe in 10,000 liters of air a day. Our sinuses serve as the “HEPA” filter for all pollutants including bacteria, mold, and viruses.  Mold and other allergens and pollutants are inhaled where the Mucosa produces a mucus that moisturizes the inside of the nose. This mucus membrane or layer protects the nose from pollutants, micro-organisms, dust and dirt.

Tiny hair cells called cilia move the layer of mucus slowly backward into the throat, where it is swallowed and later destroyed by stomach acid. Unfortunately, since the filter mechanism in your sinuses cannot be replaced, the pollutants can remain and reproduce into large fungal colonies in the sinuses while feeding on mucous production.

Nasal Rinsing

Rinsing the sinuses with saline wash containing Citridrops Dietary Supplement can help us get well and avoid unnecessary illness and pharmaceutical medicines.

I believe that daily nasal rinsing is the single most important step for any mold sufferer to aid the body’s healing process.  While Citridrops Nasal Spray is used to maintain clear sinuses from mold, full nasal rinsing physically removes the mold and other toxic debris, so that it cannot irritate the sinus in the first place. Saline irrigation augments mucociliary flow, liquefies tenacious mucus, soothes irritated tissue, augments repair processes, reduces forceful nose blowing, and improves olfaction.  Removing mucous and any infected material are critical to helping the sinuses manage swelling and irritation.

Going back centuries, neti-pots have been used for this process.  Unfortunately, neti-pots are a less than perfect delivery mechanism and become contaminated after each use.  The angle by which the neti-pot is used often pushes the discharge into the ear. In addition, proper cleaning and disinfecting is a challenging task. Using distilled, sterile or previously boiled and cooled water over ordinary tap water is advised. A small amount of baking soda is sometimes employed as a buffering agent to neutralize the pH of the irrigating solution.

The Nasopure Nasal Wash System is specially designed to produce better results with less discomfort. The patented design of the bottle allows for control of the water pressure and flow without the twisting or bending that creates the “drowning sensation” experienced with neti-pots and other bottles.  The Nasopure buffered salt packets create an optimal isotonic or hypotonic natural solution to alleviate the burning sensation.  The Nasopure bottle focuses the flow to the bottom of the sinuses creating a vacuum effect to remove debris. I appreciate the application of physics to human physiology that makes Nasopure easy to use , even for children.

Proper rinsing of the sinuses more than once a day clears the specific mold spores and accumulation of infected mucous that continues to irritate the immune system and prevent the body’s natural healing processes. Adding Citridrops Dietary Supplement to the saline solution further helps to maintain mold free sinuses. Ease, effectiveness, and comfort allows for consistency.

Cold Fogging

The second method to provide relief involves cold fogging with EC3 Mold Solution Concentrate diluted per package instructions throughout your entire home.  This is very efficient and cost effective.  By fogging everything, you are drastically reducing the fungal load in the air, carpets, floors, and surfaces that may otherwise be places for mold accumulation.  It takes several days under optimal conditions for mold to repopulate to problematic levels. When an area is fogged, it provides fresher air to breath and limits mold inhalation.  This allows the body to heal. Any moisture from fogging beads up on surfaces and evaporates, rather than penetrating and leaving items wet. I do caution you to realize that regular fogging is only a “band aid” solution to your mold issues, though, if you do not find the source of the moisture that is causing the mold in the first place.

The SANI+TIZER cold fogger that is sold by MicroBalance is the first cold fogger specifically designed for disinfection purposes.  It aerosolizes liquid particles from 5-50 microns.

Simply fog everywhere while carrying the SANI+TIZER fogger

Mold spores are roughly 3-40 microns in size.  This means the fog particles can attach to mold and dust particles in the air as well as forming a microscopic coating on surfaces where EC3 Mold Solution Concentrate can be effective and prevent mold growth.  One bottle of EC3 Mold Solution Concentrate with one gallon of distilled water will fill the fogger tank and will last for numerous passes through an entire home.  I have fogged a 4000 sq ft home as many as 6 times before purchasing EC3 Mold Solution Concentrate again. This process is very efficient and eliminates odors caused by bacteria and mold extremely well.

We recently did a mold experiment for where we tested 4 homes for mold in several places using Immunolytics mold test plates that were sent to the Lab for analysis.  Surprisingly, the two homes that regularly fog came back surprisingly clean, even though 2 weeks had passed since the last fogging.


These two procedures do take the shotgun approach to mold in your home and sinuses.  It is a less complex solution than most physician prescribed solutions; however, it is elegant in its simplicity.  Patients who choose this path are often satisfied with the quick results in feeling better until they can address the mold more clinically in both their homes and bodies.

Blasting the home and sinuses to remove mold prevents has a profound effect on healing, because even though the relief is temporary, the body can finally begin repairing itself.

The fogger does come at an expense; however, patients have yet to tell me that it wasn’t a great investment. When considering the impact mold has had on their work and personal lives, purchasing mold fogging products and equipment and a nasal rinse system provides more relief than most of the other healthcare dollars spent.  These products are all-natural, non-toxic, safe, and effective.

A less expensive option does exist:  You can purchase a gallon pump sprayer from the garden section of the hardware store for approximately $10.  It can be used to mist your home with the EC3 Mold Solution Concentrate in the same manner that you would do with the fogger.  It is less efficient than fogging and special care is required to avoid leaving belongings damp.  (A fine mist will accumulate on surfaces.) To that end, the spray does not have the full benefit of an aerosol mist at sizes small enough to attach to particles in the air or to reach corners and crevices.

I encourage anyone who tries this to comment on how they feel.

    We had our home remediated but still use the fogger to keep it safe. I have two cats and would never leave animals in the house while fogging. My husband fogs with a mask on then leaves. We stay out for a few hours. Yes a hassle but worth it. I try to plan it around my cats vet visit so we’re gone.

    Citrus oils are not safe for cats, hope you make a formula that is. Fogger is quite expensive.

      Greapefruit seed extract is used to treat infections with cats and dogs. Since the percentage is so minimal, fogging is safe for animals and people.

      You are correct the the fogger is expensive. Still, the article focused on “bang for the buck”. There is no comparison on patient testimonials regarding the most effective product and use in feeling much better, quicker. Many consider it one of the best healthcare investments made. The good news is that the fogger uses the mold solution very efficiently. One bottle can last months.

      I believe you can use your HSA to purchase with a note from your doctor to justify.
