✅ High-quality air filters – perfect indoor air quality!

1 pc. supply air filter F7. ISO 16890 classification: F7: ePM1 70%.

F7 class filters effectively capture fine particles such as solid smog particles, ensuring clean indoor air even in heavily polluted areas.

✅ Key benefits:

✅ Captures solid smog particles (PM2.5 and PM1)
✅ Captures all pollen particles, improving indoor air quality
✅ Ensures clean and healthy air in your indoor spaces
✅ Ideal for areas with heavy pollution: city centers, busy streets, industrial zones, and solid fuel heating districts

Why CleanFilter is the Best Choice for Your MVHR?

✅ Premium German Sandler AG Filter Material	Durable, safe, and highly efficient synthetic fibers
✅ Certified by Independent Labs	Verified performance by FIATEC, Germany — trusted quality
✅ Reliable Moisture-Resistant Frame	Built to last even in the most humid environments
✅ 100% Airtight Seal	Ensures no unfiltered air bypasses the filter
✅ Designed to Fit Your MVHR Perfectly	Compatible with equipment dimensions — no damage, full protection

✅ Filtration efficiency (F7):

Particle type	Efficiency	Examples
Coarse >10 µm	✅ >99%	Dust, pollen
PM10	✅ >93%	Mold spores, animal dander
PM2.5	✅ >80%	Combustion particles
PM1	✅ >70%	Solid smog particles, virus-carrying droplets (e.g., sneeze, cough)

⚙️ Filter construction:

⚙️ Type: MPL (deep pleat) – extra-large filtration surface
⚙️ Filtering material: premium 3-ply synthetic fiber (SANDLER AG)
⚙️ Moisture-resistant frame: cardboard or synthetic (depends on filter), works even at 100% RH; adapts to filter holders ensuring airtightness without damaging AHU construction
⚙️ Filtering material meets hygienic standards; resistant to microbial growth; certified according to VDI 6022 (Germany)

✅ Advantages compared to other filters:

✅ Moisture-resistant frame, suitable for European climates
✅ Airtight construction – filtering material firmly glued to the frame preventing particle leakage
✅ Adapts perfectly to ventilation unit construction without damage (especially EPP casings)

✅ 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.
