You use g3 filter media in your mvhr system to help keep the air inside clean and healthy. This filter is better than G2 but not as strong as G4. It works well to catch dust, pollen, and other dirty things. G3 media helps stop outdoor pollution from getting inside your home. It also helps keep the air moving smoothly. When you use g3, you breathe in fewer solid particles and your system works better.

Key Takeaways

  • G3 filter media traps dust, pollen, and big particles. This helps make the air inside cleaner.

  • Change G3 filters every six to twelve months. You may need to change them more often in new homes or dirty places. This keeps the filter working well.

  • G3 filters do not cost much and are simple to take care of. They work well for homes in clean places.

  • G3 filters stop big particles but not tiny dust, smoke, or germs. Use better filters if you want more protection.

  • Put in new filters the right way. This helps your MVHR system work well and last longer.

How Is G3 Filter Media Used in MVHR Systems?

G3 filter media in MVHR (Mechanical Ventilation with Heat Recovery) systems primarily captures larger airborne particles like dust, pollen, and insects. It serves as the first line of defense, protecting the heat exchanger and internal components from contamination while maintaining system efficiency.

What is g3 filter media?

G3 filter media is found in many new air systems. This filter uses PPI 30 material. It is called Coarse 50% by ISO 16890. The main job is to block big particles. You can trust it because it meets strict hygiene rules. It is certified by VDI 6022.

What g3 filters capture

When you use g3 filter media in your MVHR filter, you target some of the most common air pollutants. This media works well for homes and small offices. You can expect it to trap large particles that float in the air. These particles often come from outside or from daily activities inside your home.

Here are some of the main things g3 filters capture:

  • Pollen: If you have allergies, you know how important it is to keep pollen out. G3 filter media helps stop pollen grains from entering your living space.

  • Coarse dust: You find coarse dust in many places, like near roads or construction sites. This filter blocks much of that dust before it gets inside.

  • Automotive emissions: Cars and trucks release particles into the air. G3 filters can catch some of these larger particles, especially those from brake dust and tire wear.

  • Fibers and lint: You might not see them, but fibers from clothes and carpets float in the air. G3 filter media helps trap these, too.

  • Insect parts and plant debris: Sometimes, tiny bits of insects or plants get into the air. This filter can stop many of these from reaching your rooms.

Tip: If you live near busy roads or in an area with lots of plants, you will notice a big difference in air quality when you use a g3 filter.

You can see the types of particles g3 filter media targets in the table below:

Particle Type

Example Sources

Captured by G3?

Bacteria/viruses

People, pets

Limitations of g3 filtration

While g3 filter media does a good job with large particles, it has some limits. You need to know what it cannot do so you can make the best choice for your home.

  • Small particles pass through: G3 filters do not stop fine dust, smoke, or tiny particles from burning candles or cooking. These particles are smaller than 3 microns and can move right through the filter.

  • No protection from bacteria or viruses: If you want to block germs or very small allergens, you need a higher-grade filter.

  • Not for high-pollution areas: If you live in a city with lots of air pollution, g3 may not give you enough protection. You might need a filter with higher filtration efficiency.

  • Limited use for sensitive people: People with asthma or strong allergies may need more advanced filtration to feel safe and comfortable.

Note: G3 filter media works best for basic air cleaning. You can use it for extraction systems or in places where you only need to remove large particles. If you want to protect your health from fine dust or germs, you should look at other options.

You should choose g3 when you want simple, low-cost filtration and do not need to remove very small particles. This filter helps your MVHR system last longer by keeping big debris out. For most homes in clean areas, g3 filter media gives you a good balance between air quality and easy maintenance.

How Does G3 Filter Media Compare to G4 and G2 Filters?

G3 filter media occupies the middle ground in the filtration spectrum, with approximately 80-90% arrestance for particles larger than 10 microns. It offers better filtration efficiency than G2 filters (65-80% arrestance) but less than G4 filters (90%+ arrestance).

Filtration efficiency

When you pick a filter for your mvhr system, you want to know how well it traps particles. Filtration efficiency means what percent of particles the filter can catch. G2, G3, and G4 filters all work differently.

Here is a simple table that shows the differences:

Filter Class

Efficiency Range

G2

65% to 80%

G3

80% to 90%

G4

90% and above

G2 filters catch big particles but let more dust go through. G3 filters are better and trap more medium-sized particles. G4 filters are the best for fine particles and have the highest filtration efficiency. If you want cleaner air, you should pick G3 or G4 filters.

Use cases and pros/cons

You should think about where you live and what you need from your filter. Each filter grade is good for different places.

Filter Grade

Filtration Efficiency

Maintenance Frequency

Suitability

G2

Coarse filter for larger particles

Lower frequency

Basic air quality improvement

G3

Improved efficiency for smaller particles

Moderate frequency

Better for moderate air quality needs

G4

High efficiency for fine particles

Higher frequency

Suitable for high air quality environments

  • G2 filters are good in places with little dust or pollution. You do not need to change them a lot. They cost less but do not stop small particles.

  • G3 filters give you better protection than G2. You do not have to change them as much as G4. They are good for homes in clean or country areas.

  • G4 filters are best if you want the cleanest air. You need to change them more often. They cost more but help in cities or dusty places.

Tip: If you live in the country or want basic protection, G3 filters are a smart pick. For city homes or if you have allergies, G4 filters may be better.

Here is another table to help you choose:

Filter Type

Best Suited Environment

Pros

Cons

G3 Filter

Basic protection, rural or clean environments

Low pressure drop, cheaper

Doesn’t filter finer particles (e.g., fine dust, soot, allergens)

G4 Filter

Standard residential use in moderate air quality environments

Good balance of filtration and airflow, affordable

Still not effective against fine particles (e.g., PM2.5)

You should always pick the filter that fits your needs. Think about your air quality, how often you want to change the filter, and your budget.

Why Should You Choose G3 Filter Media for Your MVHR System?

G3 filter media is an optimal choice for MVHR (Mechanical Ventilation with Heat Recovery) systems because it effectively captures larger airborne particles while maintaining good airflow rates. This basic filtration level removes dust, pollen, and insects, providing adequate air quality for most residential applications without significantly impacting system efficiency.

When to use g3

You pick g3 filter media when you want good air and low cost. This filter is great for homes, offices, and schools. It helps make the air better but is not the strongest filter. If you live in the country or a place with clean air, g3 filter media keeps out big things like dust and pollen. You will not have to spend a lot of money or time on it. Many companies say to use G3 to M5 filters in mechanical ventilation with heat recovery systems. These filters can catch up to 95% of things floating in the air. This helps you have a cleaner and healthier space.

Tip: Use g3 filter media if you only need basic air cleaning. You get good airflow and your system works well.

Factors to consider

When you pick a filter, think about where you live, your money, and how often you want to check your system. G3 filter media gives you good filtering and does not block air too much. You save money on new filters and repairs. This helps your MVHR unit last longer and costs less to run.

  • G3 filters cost less than stronger filters.

  • They are easier to take care of and last longer.

  • Check and change your filters every six to twelve months.

  • If you live where it is dusty or dirty, change them more often.

Always look at what the maker says before you buy a filter. Makers say G3 to M5 filters work for most buildings. These filters are good for places like schools and hospitals.
