✅ 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 Type | Suggested Replacement |
|---|---|
| Activated carbon (F7-AC) | every 3 months |
| F7–F9 | every 4–6 months |
| M5 / G4 | every 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
- Check your user manual if replacing filters for the first time.
- Turn off the AHU and wait until all fans stop rotating.
- Remove the front panel or filter cover.
- Take out the old filters.
- Vacuum inside the unit if possible and wipe down filter holders with a damp cloth.
- Inspect and clean other AHU components if needed — such as rotor belt, heat exchanger, fan blades, etc.
- 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%.
- 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.
- After installation, close the cover and restart the unit.
- 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 Disease | PFAS may increase the risk of heart-related illnesses. |
| ✅ Reproductive Disorders | Can affect hormone systems, causing infertility and other reproductive issues. |
| ✅ Neurological Effects | Linked to brain development disorders and cognitive impairments in children. |
| ✅ Increased Cancer Risk | Evidence suggests PFAS may raise the risk of certain cancers. |
