Titon is reminding its ventilation systems customers about the importance of changing the filters in mechanical ventilation with heat recovery (MVHR) units regularly.
Mike Matlin, UK sales manager of Titon's Vent Systems Division, said: "Inadequate ventilation can lead to health problems and cause damp and condensation, which can also lead to mould growth. While Part F of the Building Regulations (England and Wales 2010) has helped improve the design and installation of ventilation systems, filters should not be overlooked, as they play a vital role in maintaining high levels of performance and indoor air quality."
For newbuild properties in particular, Mr Matlin added: "It's important that the filters in MVHR units are checked and cleaned at the time of handover, due to the high levels of dust and contaminants accumulated during construction. On the odd occasion, units may need a new filter before the occupier has even moved in. Where possible, it is also advisable to leave the unit on boost for the first few days of operation, to help with the removal of excessive moisture that may be contained in the new building fabric. Again, at the end of this period, a filter check would make sense."
Titon’s range of HRV Q Plus units come with G3 filters as standard (HRV10 Q Plus units have G4 filters as standard). G4 filters are a slightly higher grade of filter, but add extra resistance, which in turn may make the unit run at an increased level generating slightly more noise and power consumption.
