Common MVHR Questions

What is the purpose of MVHR filters?

MVHR filters are designed to clean the incoming and outgoing air in your ventilation system, ensuring that fresh air entering your home is free from pollutants, dust, pollen, and other harmful particles.

They also protect the internal components of the MVHR system by preventing dirt buildup, which can affect its performance and efficiency. Additionally, they help maintain indoor air quality by filtering out contaminants that could affect health, especially for allergy sufferers.

How often should I change MVHR filters?

MVHR filters should typically be replaced every 3 to 6 months, depending on the manufacturer’s recommendations and the air quality in your area.

Homes in urban or polluted areas may need more frequent changes, while rural homes with cleaner air can often go longer between replacements. Regularly checking the filters for dust buildup and adhering to the replacement schedule ensures optimal system performance and protects indoor air quality.

What types of MVHR filters are available?

There are several types of MVHR filters, each with different levels of filtration:

How do I know when my MVHR filters need replacing?

Most MVHR systems will have a filter change indicator, either on the control panel or through an app, which alerts you when it’s time to replace the filters. Additionally, if you notice reduced airflow, increased dust in the home, or unusual system noises, it may be a sign that the filters are clogged and need changing.

Regular visual inspections can also help you monitor the condition of the filters.

Can I clean and reuse MVHR filters?

Some MVHR filters can be gently vacuumed but this is not a long-term solution.

Over time filters will lose effectiveness, and fine filters like G4 (Dust Destroyers) and up should always be replaced rather than cleaned.

Is other maintenance required for the MVHR System or Unit?

Yes – Dust, Debris, and grease build up happens on the filters and in other key areas of the system as well including the two motors, heat exchanger, ducting, and air valves.  

A comprehensive service annually is recommended to keep the system running effectively, lengthen the life of the unit and maintain manufacturer warranties.
