Product type: Filters for Air Handling Units

The set includes G3 filter material pads made of high-quality PPI 30 filtering material. Classification according to ISO 16890: Coarse 50%.

G3 filters are designed to protect the air handling unit and ventilation system from contamination by larger particles like dust, bugs, and puff.

The filtering efficiency of the G3 filter:

Coarse particles: >50% (dust, pollen)
PM10 particles: <10% (mold spores, animal dander)
PM2.5 particles: - (combustion particles)
PM1 particles: - (solid smog particles, virus carriers)

Filter construction:

Type: filtering material sheets.
Filtering material: high-quality thick PPI 30.
Filtering material corresponds to hygienic requirements (resistant to microorganisms' growth). Certified according to VDI 6022 standard (Germany).

Advantages with other filters

Premium-class synthetic material made in Germany. Stronger and resistant to damage. PPI 30 filters have longer durability and can be washed.
Filters made in the EU and tested according to ISO16890.

Replacement period: The replacement period depends on outdoor air contamination. Wash filters 3-4 times. Replace after 4 the cleaning.

Additional information:

Packing: filters are packed in plastic film suitable for long-term storage.
Warranty: 2-year storage warranty if kept in proper condition and package.
Storage conditions: internal premises, RH<60%, low dustiness.
Made in the EU.

The filter is high quality for analog, perfectly suited to your air handling unit.

✅ 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.

♻️ Main Products Containing PFAS:

♻️ CleanFilter Solution

✔️ Healthier indoor air. PFAS chemicals do not enter the air or spread throughout your rooms.
✔️ Complies with the latest standards. Our filters meet current safety requirements and forthcoming regulations regarding PFAS materials.
