Understanding G4 Pre-Filters in our Air Scrubbers

Indoor air quality has become a growing concern in Kenya, especially in urban areas like Nairobi, Mombasa, and Kisumu. Whether it is due to construction dust, smoke, or allergens, clean air is essential for good health. That is why we offer high-quality air scrubbers for rent across Kenya. One key component that enhances the performance of our machines is the G4 pre-filter. This article will guide you through understanding G4 pre-filters in our air scrubbers, their function, and why they matter.

What Is a G4 Pre-Filter?

A G4 pre-filter is a type of filter used in air scrubbers to trap large particles such as dust, hair, and pollen before they reach the main HEPA or carbon filter. The term “G4” refers to its classification based on the European EN779 standard, which measures how well a filter captures particles.

Key characteristics of G4 pre-filters include:

• High dust-holding capacity
• Low air resistance for energy efficiency
• Made from synthetic or fiberglass media
• Reusable in some cases after cleaning

G4 filters can capture particles as small as 10 microns, making them excellent for general-purpose air cleaning in both homes and work sites.

Why Are G4 Pre-Filters Important?

When renting an air scrubber, most people focus only on the main HEPA filter. However, the G4 pre-filter plays an equally vital role. It acts as the first line of defense, removing larger contaminants before they clog the more expensive and sensitive HEPA filters.

Here’s why they matter:

1. Extended lifespan of HEPA filters
   By trapping larger particles early, G4 pre-filters help preserve the performance of HEPA filters, reducing replacement frequency.
2. Improved airflow
   Clean pre-filters keep the air scrubber running smoothly, maintaining optimal airflow and performance.
3. Lower maintenance costs
   Replacing a G4 pre-filter is more affordable than replacing a clogged HEPA filter.
4. Enhanced indoor air quality
   With fewer pollutants circulating in the room, you get cleaner, fresher air.

How Our Air Scrubbers Use G4 Pre-Filters

Understanding G4 pre-filters in our air scrubbers helps you appreciate how we prioritize clean air in every rental unit. Every scrubber we rent out is fitted with a pre-installed G4 filter. These filters are inspected, cleaned, or replaced after every rental to ensure top-notch performance.

Our air scrubbers are used in many scenarios:

• Construction and renovation sites
  Dust and debris from sanding, painting, or demolition are quickly captured.
• Allergy control at home
  For families dealing with allergies or asthma, the G4 filter is effective in trapping triggers like pollen and pet dander.
• Flood or fire restoration
  During post-disaster cleaning, air scrubbers with G4 pre-filters help control harmful particles.
• Offices and commercial spaces
  Regular air purification improves worker comfort and reduces the spread of airborne irritants.

Benefits for Kenyan Homes and Businesses

In Kenya, where air pollution levels vary widely, especially during the dry season, our air scrubbers provide a timely solution. Understanding G4 pre-filters in our air scrubbers means knowing how they directly benefit your home or business.

For homeowners, these filters can help manage:

• Dust from unpaved roads
• Smoke from outdoor cooking or burning trash
• Pollen from flowering plants

For businesses, particularly in construction, hospitality, and healthcare, G4 pre-filters contribute to:

• Healthier work environments
• Better compliance with indoor air quality standards
• Reduced sick days and improved productivity

How Often Should G4 Pre-Filters Be Changed?

This depends on the environment and how long the air scrubber is used. In dusty areas or active work sites, the G4 pre-filter may need cleaning or replacement every week. In cleaner environments, it can last longer. When you rent from us, we take care of the filter maintenance, so you never have to worry.

We recommend checking the pre-filter regularly if you’re renting long-term. If you notice:

• Reduced airflow
• Strange odors
• Visible dirt buildup

Then it is time to clean or replace the G4 filter.
