How to Choose the Right MVHR Filter for Your Home

Mechanical Ventilation with Heat Recovery (MVHR) systems are a crucial component of modern, energy-efficient homes. They work by removing stale air and moisture from inside your home while introducing fresh air, which is then heated by the heat recovery unit. MVHR filters play a key role in the efficiency and effectiveness of these systems, so it’s important to choose the right one.

In this post, we’ll look at what MVHR filters are, what types are available, and how to choose the right one for your home.

What are MVHR Filters?

MVHR filters are a crucial part of the MVHR system, working to remove contaminants from the air that is brought into your home. These filters can be either G4 or F7 grade, with the higher grade filters being more efficient at removing pollutants. The filters work by capturing particles such as dust, pet dander, and pollen, before they enter your home.

Types of MVHR Filters

There are two main types of MVHR filters: synthetic and natural. Synthetic filters are made from man-made materials and are designed to last for up to 6 months, while natural filters are made from materials such as cotton and wool and need to be replaced more frequently, usually after 2-3 months.

Synthetic filters are the most commonly used type of MVHR filter, as they are more efficient and have a longer lifespan. They are also more cost-effective, as they can be easily replaced and don’t require frequent maintenance.

Natural filters are a popular choice for those who are concerned about the environment, as they are biodegradable and made from sustainable materials. However, they are not as efficient as synthetic filters and need to be replaced more frequently.

How to Choose the Right MVHR Filter for Your Home

When choosing an MVHR filter for your home, there are several key factors to consider, including:

• Grade: As mentioned above, MVHR filters are available in either G4 or F7 grade, with the higher grade filters being more efficient at removing pollutants. If you have allergies or asthma, it is recommended to choose an F7 grade filter.
• Size: MVHR filters are available in different sizes, so it’s important to choose the right size for your system. If the filter is too small, it won’t work as effectively, while if it’s too large, it will cause unnecessary pressure drop, leading to reduced efficiency.
• Material: As mentioned earlier, there are two main types of MVHR filters, synthetic and natural. Decide which type is best for you based on your budget, environmental concerns, and the efficiency you require.
• Cost: MVHR filters vary in price, so it’s important to choose one that fits within your budget. Keep in mind that although synthetic filters may be more expensive upfront, they are more cost-effective in the long run as they have a longer lifespan and don’t need to be replaced as often.
• Maintenance: Consider how often the filter needs to be replaced, as well as the cost of replacement. Synthetic filters are more cost-effective and require less maintenance, while natural filters are more eco-friendly but need to be replaced more frequently.

Conclusion

MVHR filters play a crucial role in the efficiency and effectiveness of MVHR systems, so it’s important to choose the right one for your home. When choosing an MVHR filter, consider the grade, size, material, cost, and maintenance requirements.
