Clean Air Without Compromise: PFAS-Free Filters for Your Ventilation Unit!

Your home deserves fresh, clean air — every single day. According to hygiene standards, each person needs at least 36 m³/h of filtered outdoor air. Your ventilation unit brings that air in and cleans it — so proper filtration is essential.

✅ No Leaks, Complete Seal

Low-quality filters can leave gaps around the frame or shed fragile glass fibres, allowing unfiltered particles to pass through. CleanFilter’s filters are fully sealed along the edges, ensuring 100% airtightness and reliable performance.

✅ Proven Performance

Only filters tested to ISO 16890 can be trusted to perform as claimed. CleanFilter’s range — tested at Fiatec in Germany — includes:

G3–G4 (Coarse): basic protection against dust and insects
ePM10 (M5–M6): filters pollen and mould spores
ePM2.5 (M6–F7): removes combustion particles
ePM1 (F7–F9): targets smog, pesticide dust, and fine carriers of allergens

✅ Hygienic and PFAS-Free

Filters made with glass fibres may release PFAS — harmful “forever chemicals” — into your indoor air. CleanFilter uses safe synthetic fibres, certified to VDI 6022 to prevent microbial growth and ensure hygienic operation.

✅ Breathe Easy with CleanFilter

Don’t take risks with the air you breathe. Choose filters that are certified, sealed, and PFAS-free.
Trust CleanFilter — for cleaner, healthier indoor air.

Replace Your Filter — Breathe Fresher Air

A clogged or worn-out filter can reduce airflow, increase noise levels, and push up your energy bills. That’s why it’s important to replace your filters on time, following the manufacturer’s recommendations or any alerts from your ventilation system.

But not all filters are created equal. Choosing the right filter class is essential — especially if you live in an area affected by air pollution.

✅ We offer a range of filters to suit every need:

G4 / M5 – Basic Filtration
Ideal for areas with clean outdoor air. These filters offer low airflow resistance and can last up to 6–8 months.
F7 – F9 – Fine Filtration
Recommended for city centres, homes near busy roads, or industrial zones. These filters capture fine dust particles (PM2.5, PM1) and typically last 4–6 months.
Activated Carbon Filters
Perfect for areas with strong odours or high levels of gases like nitrogen dioxide or ozone. Replace every 3–4 months for best results.

⚙️Tip:

If you or your family suffer from pollen allergies, we recommend using at least an M5-class filter.

✅ A Balance Between Clean Air and Efficiency

Higher-grade filters deliver cleaner, healthier air, but may increase energy consumption slightly and require more frequent changes. Choosing the right filter helps you strike the best balance between air quality and system efficiency.

Will It Fit Your Ventilation Unit? Absolutely.

A poorly fitting filter can compromise performance — loose filters may allow unfiltered air to pass through, while overly tight ones can damage the filter frame. That’s why precise sizing is essential for ventilation units.

Thanks to our automated manufacturing process, CleanFilter products are made with less than 1 mm deviation, ensuring a secure and reliable fit every time.

Modern ventilation units are designed to use filters with gaskets — for improved sealing and effortless replacement.

That’s why CleanFilter uses high-quality materials and gaskets sourced from a trusted German supplier, helping ensure compliance with VDI 6022 hygiene standards.

For added convenience, most of our filter models include pull tabs, making removal and replacement quick and easy.

✅ Choose CleanFilter for:

Guaranteed fit
Certified hygienic quality
Hassle-free replacement

Breathe better. Install with confidence. Order your filter today!

✅ We offer filters for every need:

G4 / M5 – Basic Filtration
Ideal if your outdoor air is already clean and you want minimal airflow resistance. Lasts up to 6–8 months.
F7 – F9 – Fine Filtration
Recommended for city centres, busy roads, or industrial areas with higher levels of fine dust (PM2.5, PM1). Typically lasts 4–6 months.
Activated Carbon Filters
Best for heavily polluted areas with odours or high levels of gases such as nitrogen oxides or ozone. Replace every 3–4 months.

⚙️ Tip:

If anyone in your household suffers from pollen allergies, we recommend using at least an M5-class filter.

✅ Cleaner Air vs. Energy Use

Keep in mind: higher filtration delivers cleaner air, but may slightly increase energy use and require more frequent filter changes.
