So why is it important to change your filters?

Filters remove from the air such particles as smoke, dust, dirt and pollen etc from entering the property.  The need to check filters is very important as over time the filters will clog up with particles, which results in less air getting through to the ventilation system.  This can impact on air flow rates, that could result in the system generating noise as the ventilation system tries to work harder to achieve its initial airflow requirement.

Remember, it’s important to change your filters at least every 12 months.  Titon recommends that you do this more frequently if you live in an urban area where there is a build up of external air pollution.

Titon has a filter reminder service that is ideal to assist a homeowner in replacing filters, use the link below to register and Titon will remind you when you need to change them!
