Filters for Air Handling Units

✅ High-quality M5 class filters – reliable protection and cleaner indoor air!

The set includes: 2 pcs. M5 class filters
ISO 16890 classification: ePM10 55%

M5 class filters not only protect the air handling unit and ventilation system from larger particles but also effectively capture allergens such as pollen and mold spores.

M5 filters have a lower pressure drop compared to F7 filters, which ensures a longer service life while maintaining efficient filtration of medium-sized particles (PM10).

This set is ideal for residential areas with low pollution and occasional increases in PM10 concentrations.

✅ Filter Maintenance Recommendations

⏳ When to Replace Filters?

  • Filter contamination is monitored by a timer in the control unit. Replacement alerts appear on the display or in the mobile app.
  • ⚠️ A filter alert is just a reminder — your AHU will continue operating normally.
  • The replacement frequency depends on outdoor air quality. If you live near busy roads, gravel paths, construction sites, industrial zones, or farmland, you may need to replace filters 1.5–2× more often.
  • Most manufacturers recommend replacing filters at least twice a year: before and after the heating season.

⚙️ Recommended Filter Replacement Intervals:

Filter TypeSuggested Replacement
Activated carbon (F7-AC)every 3 months
F7–F9every 4–6 months
M5 / G4every 5–8 months

Using a G4 prefilter can extend F7–F9 filter lifespan by 2–3 months.

Return air filters (extract side) may be replaced less frequently than supply air filters (F7, F7/AC).

♻️ Reusable Filter Types

  • Wire-frame filters and filter media pads (cut-to-size materials) can be vacuumed every 2–3 months, up to 2–3 times before replacement — if permitted in your unit's manual.
  • However, panel and pocket filters are strictly single-use. Vacuuming or washing them may damage the filter and reduce efficiency. Fine dust gets trapped in the inner layers and cannot be removed.

⚙️ Step-by-Step Filter Replacement

  1. Check your user manual if replacing filters for the first time.
  2. Turn off the AHU and wait until all fans stop rotating.
  3. Remove the front panel or filter cover.
  4. Take out the old filters.
  5. Vacuum inside the unit if possible and wipe down filter holders with a damp cloth.
  6. Inspect and clean other AHU components if needed — such as rotor belt, heat exchanger, fan blades, etc.
  7. Install new filters carefully:
    • Check airflow direction — arrows on the filters must match the AHU’s airflow.
    • Typically, filters are installed before the heat exchanger; arrows should point inward toward the center.
    • If there are 3 filters and the F7/F8 filter is on the opposite side of the exchanger from G4, its arrow must point away from the exchanger.
    • Incorrect orientation can increase airflow resistance by up to 15%.
  8. If using different filter types (e.g. F7 and G4), install F7 on the outdoor air side and G4 on the extract side. The outdoor air duct is usually insulated; the extract duct is not. Refer to the manual and note whether your unit is left- or right-handed.
  9. After installation, close the cover and restart the unit.
  10. Reset the filter timer using the control device, according to the user manual.

❌ Do Not Use the Unit Without Filters

Running your ventilation unit without filters will clog the heat exchanger and contaminate the entire system. It will also void your warranty.

⏳ Why Timely Filter Replacement Matters

Dirty filters increase airflow resistance, reduce airflow, raise energy consumption, and increase operating noise. Replacing them on time ensures efficiency and extends system life.

⚠️ PFAS chemicals have been used in a wide range of products since the 1940s. During production or use, PFAS can migrate into soil, water, and air. Most of these chemicals are practically non-degradable. Numerous scientific studies indicate that PFAS chemicals may pose risks to human and animal health.

♻️ Major Health Risks:

✔️ Risk✨ Description
✅ Heart DiseasePFAS may increase the risk of heart-related illnesses.
✅ Reproductive DisordersCan affect hormone systems, causing infertility and other reproductive issues.
✅ Neurological EffectsLinked to brain development disorders and cognitive impairments in children.
✅ Increased Cancer RiskEvidence suggests PFAS may raise the risk of certain cancers.
