The Ultimate Guide to Maintaining Your Electrostatic Air Filtration Unit

Electrostatic filtration units such as the MistBuster are highly effective at capturing airborne contaminants, making them essential for clean air environments. However, to maintain peak efficiency, these units require regular maintenance. Without proper care, dirt and debris buildup can cause grounding issues and disrupt filtration. In this blog, we’ll walk you through everything you need to know about maintaining and cleaning your unit, ensuring it runs efficiently for years to come.

Why Regular Maintenance is Essential

Like any filtration system, electrostatic units accumulate particles over time. If not cleaned regularly, the collection cells become coated with dirt, reducing their effectiveness. This can lead to several issues, including:

Reduced airflow and filtration efficiency
Increased energy consumption
Potential damage to components due to grounding issues

To avoid these problems, clean your collection cells at least four times a year. Additionally, always check the indicator light—if it’s blinking or off, the unit
requires servicing.

For facilities handling large-scale cleaning, consider using an onsite or offsite service program for professional-grade maintenance.

Safety First: Handling Electrostatic Cells

Before you begin cleaning, establish a routine maintenance schedule and prioritize safety measures. Electrostatic cells contain delicate plates and wires, which can be sharp and should be handled with care.

Safety Tips:

Wear protective gear, including safety goggles and gloves.
Avoid skin contact with alkaline detergents, which can cause irritation or
burns.
Follow proper shutdown procedures before handling components.

By following these precautions, you can ensure a safe and efficient cleaning
process.

Step-by-Step Cleaning Process

Proper cleaning ensures your filtration unit remains in top condition. Follow these steps for optimal maintenance:

1. Power down and discharge the air filtration unit

Turn off and unplug the unit.
Wait 10 seconds to allow residual charge to dissipate.

Press the test button to fully discharge the system.

2. Ground the cells

Use an insulated screwdriver to ground the cells and discharge any
remaining electricity.
A small spark may occur—this is normal and indicates successful
grounding.

3. Remove the components

Carefully take out the collection cells and mesh filters.
Handle all components gently to prevent damage.

4. Option 1: Soaking method

Prepare a cleaning solution using an approved MistBuster, TriMist or SmogHog detergent mixed with 140°F water.
Submerge the collection cells for one hour.
Rinse thoroughly with water at a maximum pressure of 60 psi.

5. Alternative: Parts washer

If using a parts washer, ensure the cleaning fluid is aluminum safe.
Use a maximum pressure of 60 psi to avoid damaging delicate
components.

6. Inspect the components

Check the wires and plates for any remaining debris or damage.
If buildup is still present, remove it carefully to ensure continued
efficiency.

7. Clean the cabinet interior

Apply a degreaser to contact points within the unit to remove residue.
If you notice charred or damaged parts, replace them immediately.

Choosing the Right Cleaning Solution

For the best results, always use a MILD DEGREASING DETERGENT. This specialized detergent is designed to clean electrostatic filtration units effectively without harming their components. Using unapproved cleaning solutions may lead to:

Corrosion or damage to the collection cells
Reduced filtration efficiency
Shortened lifespan of the unit

By sticking to the recommended detergent, you can maximize the durability and performance of your filtration system.

Final Thoughts

Regular maintenance is the key to ensuring your electrostatic filtration unit operates efficiently. By following a consistent cleaning schedule, using the right safety precautions, and choosing approved cleaning solutions, you can prevent costly repairs and extend the lifespan of your unit.

Whether you clean your unit in-house or opt for an offsite service program, proper maintenance will help keep your air filtration system in peak working condition.
