High-quality replacement filter set for Vallox 51 MV, Vallox 51K MV ventilation units (Filter package nr. 32)
The Vallox 51 filterset consists of 3 parts: · Coarse filter 75% (G4) filters incoming air from insects, thick pollen and other dust · ePM1 55% fine filter cleans incoming air from fine dust that is invisible to the eye · Coarse filter 75% (G4) cleans the exhaust air and keeps the heat exchanger clean
FIlters tested by ISO 16890
F7/ePM1 55% filter class efficiency stops fungal spores, some bacteria, virus carriers, ash, cement dust, falling dust, and pollen.
F7/ePM1 filter service life time is 6-8 months, depending on the environment and ventilation regime settings.
The filter frame is made from moisture-proof carton and can be recycled.
An optional active carbon filter set can be ordered for removing unwanted odors and volatile materials.
Certified safety: Filters have passed tests according to REACH for over 250 harmful chemical substances.
Proven efficiency: Performance of filter verified in an independent laboratory according to ISO 16890 standard.
Free from carcinogens: Filters tested for TOF / PFAS particles and confirmed to be completely safe.
Filter material: Modern, synthetic two-layer filtering material which provides less air resistance (and therefore less energy consumption), high filtration efficiency levels (in the form of dust absorption), and a long filter life (involving low pressure drops).
Durable design: Built with a strong frame that resists deformation under challenging conditions. Material is glued to the frame and prevents air leakage.
Competitive pricing: Affordable rates and a large inventory of ready-to-ship filter sets.

WHY CHANGE FILTERS OVER TIME?
The producers recommend that filters be changes at least once or twice a year, at the beginning and end of the heating season. The interval also depends on the location and the intensity of ventilation.
Old and dirty filters lead to a pressure drop in the ventilation system and, as a result, the volume of fresh air inflow decreases, which worsens the indoor climate.
An old, dirty filter can contribute to the spread of mould in the ventilation system. (especially in humid climates), which can be a health hazard.
The new filter has the best air permeability levels and, as a result, savings can be made in electricity costs for the fan unit.
STORAGE AND DISPOSAL:
For long-term storage, keep in a dry place. Used filters can be disposed of with regular household waste.
